Death, Sex & Evolution

Dr. John Long

IN THIS RIVETING STORY about his remarkable discoveries from the Gogo fossil site in the Kimberly district of Western Australia, the Australian paleontologist John Long, now Vice President of Research and Collections at the Natural History Museum of L.A. County, takes us beyond just reconstructing animal morphology and into the realm of restoring ancient behavior. Long drills down deep on how we know what we know about the past, what the boundaries of knowledge are with respect to studying fossils, and how exceptional fossils contribute to reshaping our perspectives on evolution. Dr. Long, the author of the classic books The Rise of the Fishes and Swimming in Stone, compares the Hollywood view of evolution versus the scientific visage of natural history. As well, Dr. Long will explore how complex ideas in science — such as global climate change — are easily dismissed by skeptics (e.g., global warming skeptics) because the basic level of scientific literacy to begin to understand the problem involves a high level of either multidisciplinary knowledge or a high level of trust in science and how it works.

Adventures Among the Ants:
A Global Safari with a Cast of Trillions

Mark Moffett (photo by Frank J. Sulloway)

INTREPID INTERNATIONAL EXPLORER, biologist, and National Geographic photographer Mark W. Moffett, “the Indiana Jones of entomology,” takes us around the globe on a strange and colorful journey in search of the hidden world of ants. In tales from Nigeria, Indonesia, the Amazon, Australia, California, and elsewhere, Moffett recounts his entomological exploits and provides fascinating details on how ants live and how they dominate their ecosystems through strikingly human behaviors, yet at a different scale and a faster tempo. Moffett’s spectacular close-up photographs shrink us down to size, so that we can observe ants in familiar roles; warriors, builders, big-game hunters, and slave owners. We find them creating marketplaces and assembly lines and dealing with issues we think of as uniquely human — including hygiene, recycling, and warfare.

How the Economy Works:
Confidence, Crashes & Self-Fulfilling Prophecies

How the Economy Works (cover)

“OF ALL THE ECONOMIC BUBBLES that have been pricked,” the editors of The Economist recently observed, “few have burst more spectacularly than the reputation of economics itself.” Indeed, the financial crisis that crested in 2008 destroyed the credibility of the economic thinking that had guided policymakers for a generation. But what will take its place?

In this lecture based on his new book, How the Economy Works, one of our leading economists, the UCLA professor Roger Farmer, provides a jargon-free exploration of the current crisis, offering a powerful argument for how economics must change to get us out of it. Farmer traces the swings between classical and Keynesian economics since the early 20th century, gracefully explaining the elements of both theories. During the Great Depression, Keynes challenged the longstanding idea that an economy was a self-correcting mechanism; but his school gave way to a resurgence of classical economics in the 1970s — a rise that ended with the current crisis. Rather than simply allowing the pendulum to swing back, Farmer writes, we must synthesize the two. The goal, he says, is to correct the excesses of a free-market economy without stifling entrepreneurship and instituting central planning.

On Fact & Fraud:
Cautionary Tales from the Front Lines of Science

On Fact and Fraud (cover)

FRAUD IN SCIENCE is not as easy to identify as one might think. When accusations of scientific misconduct occur, truth can often be elusive, and the cause of a scientist’s ethical misstep isn’t always clear. In his lecture based on his new book, On Fact and Fraud, Caltech physicist David Goodstein looks at actual cases in which fraud was committed or alleged, explaining what constitutes scientific misconduct and what doesn’t, and outlines some ethical foundations needed to discern and avoid fraud wherever it may arise. As Caltech Vice Provost he was responsible for investigating all allegations of scientific misconduct, so he has much experience in this matter. Cases include those of Robert A. Millikan, whose historic measurement of the electron’s charge has been maligned by accusations of fraud; Martin Fleischmann and Stanley Pons and their “discovery” of cold fusion; Victor Ninov and the supposed discovery of element 118; Jan Hendrik Schön from Bell Labs and his work in semiconductors; and J. Georg Bednorz and Karl Müller’s discovery of high-temperature superconductivity, a seemingly impossible accomplishment that turned out to be real. Along the way Goodstein offers valuable insights into how modern science is practiced.

The Drunkard’s Walk:
How Randomness Rules Our Lives

The Drunkards Walk (cover)

A DRUNKARD’S WALK is a type of random statistical distribution with important applications in scientific studies ranging from biology to astronomy. Mlodinow, a visiting lecturer at Caltech and coauthor with Stephen Hawking of A Briefer History of Time, takes us on a walk through the hills and valleys of randomness and how it directs our lives more than we realize. Mlodinow introduces important historical figures such as Bernoulli, Laplace and Pascal, and defines such tricky concepts as regression to the mean and the law of large numbers, which should help readers as they navigate the daily deluge of election polls and new studies on how to live to 100.

Natural Experiments of History

Jared Diamond

SOME CENTRAL QUESTIONS in the natural and social sciences can’t be answered by controlled laboratory experiments, often considered to be the hallmark of the scientific method. This impossibility holds for any science concerned with the past. In addition, many manipulative experiments, while possible, would be considered immoral or illegal. One has to devise other methods of observing, describing, and explaining the world. Jared Diamond, author of the Pulitzer-prize winning Guns, Germs, and Steel and the bestselling work in environmental history Collapse, here reveals for the first time his methodology in the applied use of natural experiments and the comparative method. In this lecture based on his new edited volume, Natural Experiments of History, Diamond presents eight comparative studies drawn from history, archaeology, economics, economic history, geography, and political science. The studies cover a spectrum of approaches, ranging from a non-quantitative narrative style to quantitative statistical analyses. The studies range from a simple two-way comparison of Haiti and the Dominican Republic, which share the island of Hispaniola, to comparisons of 81 Pacific islands and 233 areas of India. The societies discussed are contemporary ones, literate societies of recent centuries, and non-literate past societies.

2012 and Counting

A NASA Scientist Answers the Top 20 Questions About 2012

PUBLIC CONCERN ABOUT DOOMSDAY IN December 2012 has blossomed into a major new presence on the Internet. This fear has begun to invade cable TV and Hollywood, and it is rapidly spreading internationally. The hoax originally concerned a return of the fictitious planet Nibiru in 2012, but it received a big boost when conspiracy theory websites began to link it to the end of the Mayan calendar long count at the winter solstice (December 21) of 2012. Over the past year, many unrelated groups have joined the doomsday chorus, including Nostradamus advocates, a wide variety of eschatological Christian, Native American, and spiritualist sects, and those who fear comet and asteroid impacts or violent solar storms. At the time of this writing there are more than 175 books listed on Amazon.com dealing with the 2012 doomsday. The most popular topics are the Mayan calendar and spiritual predictions that the disaster in 2012 will usher in a new age of happiness and spiritual growth. Quite a few authors are cashing in with manuals on how to survive 2012.

As this hoax spreads, many more doomsday scenarios are being suggested, mostly unrelated to Nibiru. These include a reversal of the Earth’s magnetic field, severe solar storms associated with the 11-year solar cycle (which may peak in 2012), a reversal of Earth’s rotation axis, a 90- degree flip of the rotation axis, bombardment by large comets or asteroids, bombardment by gamma rays, or various unspecified lethal rays coming from the center of the Milky Way Galaxy or the “dark rift” seen in a nearby galactic spiral arm. A major theme has become celestial alignments: supposedly the Sun will align with the galactic center (or maybe with the Milky Way Dark Rift) on December 21, 2012, subjecting us to mysterious and potentially deadly forces.

Unlike most pseudoscience stories, there seems to be no factual core on which the Nibiru- 2012 hoax has been constructed. This is different from, for example, the claims of aliens and a crashed UFO at Roswell, New Mexico. The alien stories are a fabrication, but the core fact is that an instrumented balloon did crash in Roswell on July 7, 1947. There is no similar factual core to Nibiru—just dubious “predictions” from psychics, or the Mayans, or Nostradamus. The rest is pure fiction.

I answer questions from the public submitted online to a NASA website, and over the past two years the Nibiru-2012 doomsday has become the dominant topic people ask about. Many are curious about things they have seen on the Internet or TV, but many are also angry about supposed government cover-ups. As one wrote “Why are you lying about Nibiru? Everyone knows it is coming.” Others are genuinely frightened that the world will end just three years from now. My frustration in answering questions piecemeal motivates this “Twenty Questions” format to organize the facts and shine a skeptical light on this accumulation of myths and hoaxes.

1. What is the origin of the prediction that the world will end in December 2012?

The story started with claims that Nibiru, a supposed planet discovered by the Sumerians, is headed toward Earth. Zecharia Sitchin, who writes fiction about the ancient Mesopotamian civilization of Sumer, claimed in several books (e.g., The Twelfth Planet, published in 1976) that he has found and translated Sumerian documents that identify the planet Nibiru, orbiting the Sun every 3600 years. These Sumerian fables include stories of “ancient astronauts” visiting Earth from a civilization of aliens called the Anunnaki. Then Nancy Lieder, a self-declared psychic who claims she is channeling aliens, wrote on her website Zetatalk that the inhabitants of a fictional planet around the star Zeta Reticuli warned her that the Earth was in danger from Planet X or Nibiru. This catastrophe was initially predicted for May 2003, but when nothing happened the doomsday date was recalculated (a standard procedure for doomsdayers) and moved forward to December 2012. Only recently have these two fables been linked to the end of the Mayan long-count at the winter solstice in 2012—hence the predicted doomsday date of December 21, 2012.

2. The Sumerians were the first great civilization, and they made many accurate astronomical predictions, including the existence of the planets Uranus, Neptune and Pluto. So why should we not believe their predictions about Nibiru?

Nibiru is a name from Babylonian astrology sometimes associated with the god Marduk. Nibiru appears as a minor character in the Babylonian creation poem Enuma Elish as recorded in the library of Assurbanipal, King of Assyria (668–627 BCE). Sumer flourished much earlier, from about the 23rd century to the 17th century BCE. The claims that Nibiru is a planet and was known to the Sumerians are contradicted by scholars who (unlike Zecharia Sitchin) study and translate the written records of ancient Mesopotamia. Sumer was indeed a great civilization, important for the development of agriculture, water management, urban life, and especially writing. However, they left few astronomical records and they most certainly did not know about Uranus, Neptune or Pluto. They also had no understanding that the planets orbited the Sun, an idea that first developed in ancient Greece two millennia after the end of Sumer. Claims that Sumerians had a sophisticated astronomy, or that they even had a god named Nibiru, are the product of Sitchin’s imagination.

3. How can you deny the existence of Nibiru when NASA discovered it in 1983 and the story appeared in leading newspapers? At that time you called it Planet X, and later it was named Xena or Eris.

IRAS (the NASA Infrared Astronomy Satellite, which carried out a sky survey for 10 months in 1983) discovered many infrared sources, but none of them was Nibiru or Planet X or any other objects in the outer solar system. Briefly, IRAS cataloged 350,000 infrared sources, and initially many of these sources were unidentified (which was the point, of course, of making such a survey). All of these observations have been followed up by subsequent studies with more powerful instruments both on the ground and in space. The rumor about a “tenth planet” erupted in 1984 after a scientific paper was published in Astrophysical Journal Letters titled “Unidentified point sources in the IRAS minisurvey,” which discussed several infrared sources with “no counterparts.” But these “mystery objects” were subsequently found to be distant galaxies (except one, which was a wisp of “infrared cirrus”), as published in 1987. No IRAS source has ever turned out to be a planet. A good discussion of this whole issue is to be found on Phil Plait’s website. The bottom line is that Nibiru is a myth, with no basis in fact. To an astronomer, persistent claims about a planet that is “nearby” but “invisible” are just plain silly.

4. Maybe we should be asking about Planet X or Eris, not Nibiru. Why does NASA keep secret the orbit of Eris?

“Planet X” is an oxymoron when applied to a real object. The generic term has been used by astronomers over the past century for a possible or suspected object. Once the object is found, it is given a real name, as was done with Pluto and Eris, both of which were once referred to as Planet X. If a new object turns out to be not real, or not a planet, then you won’t hear about it again. If it is real, it is no longer called Planet X. Eris is one of several dwarf planets recently found by astronomers in the outer solar system, all of them on normal orbits that will never bring them near Earth. Like Pluto, Eris is smaller than our Moon. It is very far away, and its orbit never brings it closer than about 4 billion miles. There is no secret about Eris or its orbit, as you can easily verify by googling it or looking it up in Wikipedia.

5. Do you deny that NASA built a South Pole Telescope (SPT) to track Nibiru? Why else would they build a telescope at the South Pole?

There is a telescope at the South Pole, but it was not built by NASA and it is not used to study Nibiru. The South Pole Telescope is supported by the National Science Foundation, and it is a radio telescope, not an optical instrument. It cannot take visible light images or photos. You can look it up on Wikipedia. The Antarctic is a great place for astronomical infrared and short-wave-radio observations, and it also has the advantage that objects can be observed continuously without the interference of the day-night cycle. I should add that it is impossible to imagine a way in which an object can be seen only from the South Pole. Even if it were due south of the Earth, it could be seen from the entire southern hemisphere.

6. There are many photos and videos of Nibiru on the Internet. Isn’t that proof that it exists?

The great majority of the photos and videos on the Internet are of some feature near the Sun (apparently supporting the claim that Nibiru has been hiding behind the Sun for the past several years). These are actually false images of the Sun caused by internal reflections in the lens, often called lens flare. You can identify them easily by the fact that they appear diametrically opposite the real solar image, as if reflected across the center of the image. This is especially obvious in videos, where as the camera moves, the false image dances about always exactly opposite the real image. Similar lens flare is a source of many UFO photos taken at night with strong light sources such as streetlights in the frame. I am surprised that more people don’t recognize this common photo artifact. I am also amazed that these photos showing something nearly as large and bright as the Sun (a “second sun”) are accepted together with claims made on some of the same websites that Nibiru is too faint to be seen or photographed except with large telescopes.

One widely reported telescopic photo shows two views of an expanding gas cloud far beyond the solar system, which is not moving; you can see this from the fact that the stars are the same in both pictures. A sharp-eyed reader on my website identified these photos as a gas shell around the star V838 Mon. Wikipedia has a nice write-up and a beautiful photo of it from the Hubble. Another high school student was initially impressed by posted images of a red blob that were said to be of Nibiru. Then he worked out in his Photoshop class how to make just such pictures starting from scratch. One video posted in summer 2008 on YouTube shows a guy standing in his kitchen claiming that one of the objects discovered by NASA’s x-ray telescope is Nibiru. What is his evidence? That since this false-color x-ray image released by NASA is blue, this must really be a nearby planet with an ocean. This would be hilarious if it were not used to frighten people.

7. Can you explain the fact that the area at (5h 53m 27s, -6 10′ 58″) has been blackened out in Google Sky and Microsoft Telescope? People suggest that these have been blackened out because those are the co-ordinates where Nibiru is located at present.

Several people have asked me about this blank rectangle in Orion in Google Sky, which is a presentation of images from the Sloan Digital Survey. This can’t be a “hiding place” for Nibiru, since it is a part of the sky that could be seen from almost everywhere on the Earth in the winter of 2007–08 when much of the talk about Nibiru began. Plus, that would contradict the claims that Nibiru was hiding behind the Sun or that it could be seen only from the southern hemisphere. But I too was curious about this blank rectangle, so I asked a friend who is a senior scientist at Google. He replied that he “found out that the missing data is due to a processing error in the image stitching program we use to display the Sloan survey images. The team assures me that in the next run through, this will be fixed!”

8. If the government knew about Nibiru, wouldn’t they keep it a secret to avoid panic? Isn’t it the government’s job to keep the population at ease?

There are many objectives of government, but they do not include keeping the population at ease. My experience is that sometimes parts of the government do just the opposite, as in the frequent references to various terrorist threats or warnings about driving accidents on long holiday weekends, which are no more dangerous than any other time. There is a long history of associating bad things with political opponents (older readers will remember the “missile gap” in the 1960 election, younger ones will note the many current references to who is or is not keeping the U.S. safe from terrorists). Further, social scientists have pointed out that many of our concepts of public panic are the product of Hollywood, while in the real world people have a good record of helping each other in a time of danger. I think everyone also recognizes that keeping bad news secret usually backfires, making the issue even worse when the facts finally come out. And in the case of Nibiru, these facts would come out very soon indeed.

Even if it wanted to, however, the government could not keep Nibiru a secret. If Nibiru were real, it would be tracked by thousands of astronomers, amateurs as well as professionals. These astronomers are spread all over the world. I know the astronomy community, and these scientists would not keep a secret even if ordered to. You just can’t hide a planet on its way into the inner solar system!

9. Why does the Mayan calendar say the world will end in 2012? I have heard that they have been pretty accurate in the past with other planetary predictions. How can you be sure you know more than they did?

Calendars exist for keeping track of the passage of time, not for predicting the future. The Mayan astronomers were clever, and they developed a very complex calendar. Ancient calendars are interesting to historians, but of course they cannot match the ability we have today to keep track of time, or the precision of the calendars currently in use. The main point, however, is that calendars, whether contemporary or ancient, cannot predict the future of our planet or warn of things to happen on a specific date such as 2012.

I note that my desk calendar ends much sooner, on December 31, 2009, but I do not interpret this as a prediction of Armageddon. It is just the beginning of a new year.

10. What is the polar shift theory? Is it true that the Earth’s crust does a 180-degree rotation around the core in a matter of days if not hours? Does this have something to do with our solar system dipping beneath the galactic equator?

A reversal in the rotation of Earth is impossible. It has never happened and never will. There are slow movements of the continents (for example Antarctica was near the equator hundreds of millions of years ago), but that is irrelevant to claims of reversal of the rotational poles. However, many of the disaster websites pull a bait-and-switch to fool people. They claim a relationship between the rotation and the magnetic field of Earth, which does change irregularly with a magnetic reversal taking place, on average, every 400,000 years. As far as we know, such a magnetic reversal does not cause any harm to life on Earth. A magnetic reversal is very unlikely to happen in the next few millennia, anyway. But the 2012ers falsely claim that a magnetic reversal is coming soon (in 2012 of course) and that this is the same as, or will trigger, a reversal of Earth’s rotational poles. The bottom line is this: (a) rotation direction and magnetic polarity are not related; (b) there is no reason to expect a reversal of magnetic polarity any time soon, or to anticipate any bad effects on life when it does eventually happen; (c) a sudden shift in the rotational pole with disastrous consequences is impossible. Also, none of this has anything to do with the galactic equator or any of the other nonsense about alignments that appears on many of the doomsday websites.

11. When most of the planets align in 2012 and planet Earth is in the center of the Milky Way, what will the effects of this be on planet Earth? Could it cause a pole shift, and if so what could we expect?

There is no planet alignment in 2012 or any other time in the next several decades. As to the Earth being in the center of the Milky Way, I don’t know what this phrase means. If they are referring to the Milky Way Galaxy, we are some 30,000 light years from the center of this spiral galaxy. We circle the galactic center in a period of 225–250 million years, always keeping approximately the same distance. Concerning a pole shift, I also don’t know what this means. If it means some sudden change in the position of the pole (that is, the rotation axis of the Earth), then that is impossible, as noted above. What many websites do discuss is the alignment of the Earth and Sun with the center of the Milky Way in the constellation of Sagittarius. This happens every December, with no bad consequences, and there is no reason to expect 2012 to be different from any other year.

12. When the Sun and the Earth line up on the galactic plane at the same time with the black hole being in the center couldn’t that cause something to happen, due to the fact that the black hole has such a strong gravitational pull?

There is a supermassive black hole at the center of our galaxy, and like any concentration of mass it exerts gravitational force on the rest of the galaxy. However, the galactic center is very far away, approximately 30,000 light years, so it has negligible effects on our solar system and Earth. There are no special forces from the galactic plane or the galactic center. The only important force that acts on the Earth is the gravitation of the Sun and Moon. As far as the influence of the galactic plane, there is nothing special about this location. The last time the Earth was in the galactic plane was several million years ago. Claims that we are about to cross the galactic plane are untrue.

13. I am scared about the fact that the Earth will enter the Dark Rift in the Milky Way. What will this do? Will the Earth be swallowed up?

The “dark rift” is a popular name for the broad and diffuse dust clouds in the inner arm of the Milky Way Galaxy, which block our view of the galactic center. The entire “galactic alignment” scare is ridiculous. Late in December the Sun is always approximately in the direction of the center of the Galaxy as seen from the Earth, but so what? Apparently the scaremongers have decided to use these meaningless phrases about “alignments” and the “dark rift” and “photon belt” precisely because they are not understood by the public. As far as the safety of the Earth is concerned, the important threats are from global warming and loss of biological diversity, and perhaps someday from collision with an asteroid or comet, not the pseudoscientific claims about 2012.

14. I have heard that the Earth’s magnetic field will flip in 2012 just when the strongest level of solar storms in history is predicted to take place. Will this kill us or destroy our civilization?

Near solar maximum (which happens approximately every 11 years), there are many more solar flares and coronal mass ejections than near solar minimum. Flares and mass ejections are no danger for humans or other life on Earth. They could endanger astronauts in deep space or on the Moon, and this is something that NASA must learn to deal with, but it is not a problem for us. Large outbursts can interrupt radio transmissions, cause bright displays of the aurora (Northern and Southern Lights), and damage the electronics of some satellites in space. Today many satellites are designed to deal with this possibility, for example by switching off some of their more delicate circuits and going into a “safe” mode for a few hours. In extreme cases solar activity can also disrupt electrical transmissions on the ground, possibly leading to electrical blackouts, but this is rare.

The last solar maximum occurred in 2001, so the next one was predicted for around 2012, 11 years later. However, the most recent solar minimum was unusual, with a period of a couple of years with almost no sunspots or other indications of solar activity, so scientists now guess that the next maximum will be delayed, perhaps to 2013. However, the details of the solar cycle remain basically unpredictable.

It is true that the Earth’s magnetic field protects us by creating a large region in space, called the Earth’s magnetosphere, within which most of the material ejected from the Sun is captured or deflected, but there is no reason to expect a reversal of magnetic polarity any time soon. These magnetic reversals happen, on average, only once in 400,000 years.

15. I am confused about a report on the Fox News website that in 2012 a “Powerful Solar Storm Could Shut Down U.S. for Months.” They referred to a report from the National Academy of Sciences that was commissioned and paid for by NASA. If nothing is going to happen as a result of the event in 2012, why would NASA allow such nonsense to be reported?

NASA is pleased with the National Research Council report on heliophysics. As noted, this report includes a worst-case analysis of what could happen today if there were a repetition of the biggest solar storm ever recorded (in 1859). The problem is the way such information can be used out of context. There is no reason to expect such a large solar storm in the near future, certainly not in 2012 specifically. The reference to “the event in 2012” illustrates this problem. There is no prediction of an “event in 2012.” We don’t even know if the next solar maximum will take place in that year. The whole 2012 disaster scenario is a hoax, fueled by ads for the Hollywood science-fiction disaster film 2012. I can only hope that most people are able to distinguish Hollywood film plots from reality.

16. All my school friends are telling me that we are all going to die in the year 2012 due to a meteor hitting Earth. Is this true?

The Earth has always been subject to impacts by comets and asteroids (as has the Moon, as you can see because it has no atmosphere to erode the impact craters), although big hits are very rare. The last big impact was 65 million years ago, and that led to the extinction of the dinosaurs. Today NASA astronomers are carrying out the Spaceguard Survey to find any large near-Earth asteroids long before they hit. We have already determined that there are no threatening asteroids as large as the one that killed the dinosaurs. All this work is done openly with the discoveries posted every day on the NASA NEO Program Office website, so anyone can see that nothing is predicted to hit in 2012.

17. If Nibiru is a hoax, why doesn’t NASA issue a denial? How can you permit these stories to circulate and frighten people? Why doesn’t the U.S. government do something about it!

If you go to the NASA home page, nasa.gov, you will see many stories that expose the Nibiru-2012 hoax. Try searching nasa.com under “Nibiru” or “2012”. There is not much more that NASA can do. These hoaxes have nothing to do with NASA and are not based on NASA data, so we as an agency are not directly involved. But scientists, both within NASA and outside, recognize that this hoax with its effort to frighten people is a distraction from more important scientific concerns, such as global warming and loss of biological diversity. We live in a country where there is freedom of speech, and that includes the freedom to lie. We should be glad there are no censors. But if we will use common sense we can recognize the lies. As we approach 2012, the lies will be come even more obvious.

18. Can you prove to me that Nibiru is a hoax? There are so many reports that something terrible will happen in 2012. I need proof because the government and NASA are keeping so much from us.

Such questions should be put to the doomsday advocates to prove that what they are saying is true, not to NASA to prove it is false. If someone claimed on the Internet that there were 50-foot tall purple elephants walking through Cleveland, would anyone expect NASA to prove this wrong? The burden of proof falls on those who make wild claims. Remember the often-quoted comment from Carl Sagan that extraordinary claims require extraordinary evidence.

However, I think that astronomers have reached the point where we can offer extremely strong arguments that Nibiru does not exist. A large planet (or a brown dwarf) in our solar system would have been known to astronomers for many years, both indirectly from its gravitational perturbations on other objects and by direct detection in the infrared. The NASA Infrared Astronomy Satellite (IRAS) carried out the first allsky survey in 1983, and several subsequent surveys would also have seen Nibiru if it were there. Further, if a large mass passed through the inner solar system every 3600 years, we would see its disruptive effects on the orbits of the inner planets, and we don’t.

But don’t take my word for it. Just use common sense. Have you seen Nibiru? In 2008 many websites said it would be visible to the naked eye in spring 2009. If a large planet or brown dwarf were headed for the inner solar system in 2012, it would already be tracked by thousands of astronomers, both professional and amateur, all over the world. Do you know any amateur astronomers who are watching it? Have you seen any photos or discussion of it in the big popular astronomy magazines such as Astronomy or Sky & Telescope? Just think about it. No one could hide something like Nibiru if it existed.

19. What about the scary ads for the new film 2012? They tell us to look at these Internet sites to verify the doomsday threat.

The pseudoscientific claims about Nibiru and a doomsday in 2012, together with distrust of the government, are being amplified by publicity for the new film from Columbia Pictures titled 2012, to be released in November 2009. The film’s trailer, appearing in theaters and on their website, shows a tidal wave breaking over the Himalayas, with the following words: “How would the governments of our planet prepare 6 billion people for the end of the world? [long pause] They wouldn’t. [long pause] Find out the Truth. Google search 2012.”

The film publicity includes a faux scientific website for “The Institute for Human Continuity”, which is entirely fictitious. According to this website, the IHC is dedicated to scientific research and public preparedness. Its mission is the survival of humanity. The website explains that the Institute was founded in 1978 by international leaders of government, business, and science. They say that in 2004, IHC scientists confirmed with 94% certainty that the world would be destroyed in 2012. This website encourages people to register for a lottery to select those who will be saved; a colleague submitted the name of her cat, which was accepted. According to Wikipedia, creating this sort of fake website is a new advertising technique called “Viral Marketing,” by analogy with computer viruses.

20. Is it possible that the influx of questions you describe is part of some kind of campaign for a book or movie, in the hopes that the volume of denials is taken as more “evidence” that there is a conspiracy?

I ask myself the same questions every day, as the volume of mail I receive about Nibiru (along with various alignments and pole shifts) keeps increasing—now more than 20 per week. Clearly there is money to be made from people’s fear about an approaching doomsday. Many websites are selling books and tapes about Nibiru or even “survival kits.” It is all very sad, given the many real issues such as global warming and the financial collapse on which our attentions should be focused. In the final chapter of a new astronomy book (The Hunt for Planet X) Govert Shilling writes: “There is plenty to do for the debunkers—the archaeologists and astronomers who take a long and skeptical look at the tidal wave of Nibiru nonsense and explain with scientific precision what is wrong with this cosmic fairy-tale. They will have their work cut out in the next few years. And on December 22, 2012 there will be a new pseudoscientific cock-and-bull story making the rounds and the whole circus will start all over again, because no matter how many new celestial bodies are found in our solar system, there will always be a need for a mysterious Planet X.”

SOME CENTRAL QUESTIONS in the natural and social sciences can’t be answered by controlled laboratory experiments, often considered to be the hallmark of the scientific method. This impossibility holds for any science concerned with the past. In addition, many manipulative experiments, while possible, would be considered immoral or illegal. One has to devise other methods of observing, describing, and explaining the world.

Come early for our $5–$10 book sale! (remainders / duplicates / review books).

JARED DIAMOND, author of the Pulitzer-prize winning Guns, Germs, and Steel and the bestselling work in environmental history Collapse, here reveals for the first time his methodology in the applied use of natural experiments and the comparative method. In this lecture based on his new edited volume, Natural Experiments of History, Diamond presents eight comparative studies drawn from history, archaeology, economics, economic history, geography, and political science.

Why Do Women Have Sex? Here’s Why. 

by Victoria Bekiempis

ROMANTIC CRADLING AND ROUGH HAIR PULLING. Power trips and jealous fits. Bouquets and, occasionally, belts. Sometimes, even, unbridled religious ecstasy. As teens, we giddily whisper at sleepovers about it. It’s the subject of exaggerated locker room play-by-plays, as well as sloshed, sloppily narrated barroom tales. It’s in the infamous Porky’s movies as well as in urban legends about a mythic aphrodisiac called the Spanish fly.

book cover

The subject of women’s sexual motivations — in plain speak, our turn-ons and turn-offs — isn’t entirely original. The new book, Why Women Have Sex, authored by University of Texas psychologists Cindy M. Meston and David M. Buss, is nevertheless distinct. That’s because their oeuevre is a serious, albeit accessible, discussion of a subject that has been largely ignored by academia. The book effectively explores the little-studied relationship between psychology, physiology and evolutionary pressures on female sexuality.

What spurred the project was a prior, published study by the authors in which women had identified 237 different reasons why they had sex. The basis of this book thus draws on some 1000 women and several years of study to go beyond the running explanations of female sexuality: pleasure and reproduction. To achieve this, Meston and Buss created an anonymous Internet questionnaire. Participating women answered questions about their sexual penchants and proclivities. This data became the basis of the book. These word-for-word accounts, in fact, comprise a large — and very entertaining — chunk of the book. They give a raw, organic edge to a subject that merits it, along with a sense of humanity to something that is primordially enmeshed in our existential experience. This is a subject that could easily — and inappropriately — be stripped and sterilized in conventional, academic writing. This is because there are behaviors that when described from an unbiased third-person perspective can seem to generate a reaction of “nobody’s really like that — I’ve never heard of anyone doing that.” Without first-person accounts of unexpected sexual M.O.s, it seems, some data might be hard to believe.

For example, one woman’s description of confidence-building sex — when a woman engages in sex for an ego boost, really — conveyed a behavior that might be otherwise difficult to describe (or thought of as being the stuff of silver screen femmes fatales, perhaps). She writes: “I had sex with a couple of guys because I felt sorry for them. These guys were virgins and I felt bad that they had never had sex before.…I felt power over them, like they were weaklings under me and I was in control.” Another participant’s recounting of a difficult-to-explain motivation — pity sex — is also in this category of seemingly (but not really) unusual motivations: “I hate letting people down, or hurting people, when I think that I can avoid it…I ended up dating him just to make him feel better about himself, and because I felt like I had led him on, so I ‘owed him.””

Granted, a lot of the explanations are obvious, expected, and quotidian for any chick who’s ever read an issue of Cosmopolitan. Heck, they probably even make sense to the Maxim-reading, Y-chromosome crowd. We have sex, the authors write, for the usual reasons: Love. Attractiveness. Duty. Money. Boredom. Revenge. Even coercion.

We have sex because we don’t want to be the last chick in our social circles to “loose” our virginity and be thought of as frigid and unloving. We have sex to get rid of headaches, to placate nagging partners. And dammit, we have sex out of a sense of curiosity. Sometimes, we want to see if that studly next door neighbor’s reputation holds water. Sometimes, even, we want to see if ethnicity plays a role in lovemaking!

But Meston and Buss also identified the unexpected. Some women, er, get it on to get close to god (really, no joke!). As one participant wrote: “It was a dream come true, being with this incredible man. I was able to lose myself and see God, where the edges of the dream-world and the real world met.”

What fascinated me, both as a woman and a reader, was the authors’ argument that a lot of our sexual motivations stem from evolutionary pressures. This drive doesn’t just include hardwiring toward making babies, they posit. Rather, natural selection has programmed women to keen into, and pursue, men with certain traits. For example, what’s that indiscernible scent that drives us women up the wall? That’s the smell of genes signifying immunological compatibility. What is it about those washboard abs and tall bod that turns us on so much? A man with both probably won’t be out-contended in physical competitions with other men. And the latter more generally implies good health and thus a good genetic pick for mating and offspring.

This entertaining — and primal — description of human attraction, however, lends itself to what might be two flaws of the book, one epistemic and one practical. On the one hand, Why Women Have Sex delves so specifically into our sexual motivations that it’s almost like a lesson in excess reductionism. Of course there’s a chemical and molecular basis to human sexuality, as there is for a vast range of other human behaviors. Is describing post-breakup blues in terms of sudden, rapid hormone drops more accurate or important than describing it with the typical monikers of heartbreak? How it feels to be dumped doesn’t seem to be aptly conveyed in an endochronological context, no matter how fascinating a description of the exact molecular and biochemical pathways might be.

Maybe this is just a tension between folk psychology and scientific psychology, and the sense of something being lost in translation. For example, let’s say a girl has a crush on a tall boy. Yes, it could be argued that the attraction is actually the primal being in her, jonesin’ for a fit mate — tallness a proxy for good genes, biological fitness, etc. When it comes down to it, though, this just doesn’t gel. Maybe I’m a hopeless romantic, but the biological fitness explanation doesn’t fully capture the terror of butterflies in that girl’s stomach or the dizzy, exhilarated whirr of eye contact with said boy. As much as her interest might ignite the reproduction-inclined flames, there seems to be a large amount of conscious decision and personal discretion involved as well.

Why Sex is Fun?

I’m a very rational woman, and I rarely let emotion get involved in problem solving. The extreme, scientific description of love and romance and attraction, however, rather unscientifically neglects a key characteristic identified by thousands of scholars familiar with the topic, from Plato and Shakespeare to Freud and Marilyn French. So much of this subject seems to deal with the ephemeral, the unknown, that sense of “je ne sais quoi.” When so much love is mixed, sometimes mired, with this gray, when difficulties definitely outweigh any evolutionary ‘pro’ toward pursuing a relationship (as we’ve all seen), I must wonder: Is it a rule that we go for evolution-favored traits, or more so, something that happens often but is not necessarily a law? Of course, that could be the irreparable sap in me talking.

As well, the breadth of Why Women Have Sex is so general and so extensive that I’m left wondering whether it says anything meaningful about women’s sexuality. When confronted with such a vast array of explanations and data, I’m not really sure what to make of it. Yes, the authors answer the “why women have sex” question to a certain degree, but I was left wanting an overarching “meta-why?” if one exists. And if such a “meta-why?” does not exist, I’d like to know “why not?”

These quibbles aside, however, Why Women Have Sex makes for a great survey of female sexuality. It works. I often felt that I was reading a rather entertaining textbook for an introductory course on human sexuality. And, it should be said, that the focus of the book wasn’t the more ephemeral aspects of attraction and lust isn’t problematic to the authors’ aim. It would be unfair to criticize the book for focusing on an aspect of female life that science has greatly ignored when that’s kind of the point.

From an entertainment standpoint, too, the book succeeds. On more than one occasion, in fact, I called up my friends to read them whole paragraphs. That there might be an evolutionary explanation behind the allure of tall, dark and handsome men is perfect for a telephonic gabfest (intellectual girl talk, if you will.) As a woman and a reader, I think the book did a solid job of exploring the whys of female sexual motivations.

In the world of Bigfoot, good evidence is hard to come by. Anecdotes and blurry photos keep the documentaries coming, but most skeptics agree that a body or a living specimen are needed to confirm the existence of a large North American mystery mammal.

But what of alleged Bigfoot footprints? One expert claims that at least some track castings contain proof of an actual unknown ape. That expert is retired law enforcement agent Jimmy Chilcutt — and he’s agreed to come talk with the skeptics on MonsterTalk.

36 Arguments for the Existence of God: A Work of Fiction

Dr. Rebecca Newberger Goldstein

IN THIS REVEALING TALK based on her compelling new novel, the award-winning writer and MacArthur “Genius” Fellow Rebecca Goldstein (Ph.D. in philosophy from Princeton and author of The Mind-Body Problem, Properties of Light, and studies of Kurt Gödel and Baruch Spinoza), shows that the tension between belief and skepticism cannot be understood through rational argument alone. It also must be explored from the point of view of individual people caught in the raptures and torments of religious experience in all their variety. 36 Arguments for the Existence of God plunges into the great debate of our day: the clash between faith and reason. World events are being shaped by fervent believers at home and abroad, while a new atheism is asserting itself in the public sphere. On purely intellectual grounds the skeptics would seem to have everything on their side. Yet people refuse to accept their seemingly irrefutable arguments and continue to embrace faith in God as their source of meaning, purpose, and comfort. Why? Goldstein gives us her answer through fiction and philosophy.
