This section is about hoaxes, quackery and examples of non-critical thinking.

The email started with a list of recipients that was longer, and arguably more impressive, than the holy lineage at the start of the New Testament: dozens of people from Harvard and HarperCollins and The Wall Street Journal. This was a highbrow crowd. Then it got down to business. I was invited by a lawyer named Pearlas Sanborn to participate in a Microsoft/AOL/Intel email beta test designed to help Internet Explorer maintain its dominance in the marketplace. But first they needed more testers. "When you forward this email to friends, Microsoft can and will track it (if you are a Microsoft Windows user) for a two-week time period. For every person that you forward this email to, Microsoft will pay you $245, for every person that you sent it to that forwards it on, Microsoft will pay you $243, and for every third person that receives it, you will be paid $241."

Robots have been making significant inroads into our culture over the last few years. They're roaming on and around distant planets, building cars, vacuuming the rug and even serving as surrogate pets. But it may surprise you to learn that sophisticated androids have been walking the earth since at least the late 1800s - achieving feats that still haven't been equalled in the 21st century. (One prototype actually took part in World War One.) The History of Robots in the Victorian Era follows the careers of these early automatons, and at the same time, tests the limits of human credibility.

Launched in July 2000 to tell the amazing story of "Boilerplate" (history's first mechanical soldier created in 1893), the website has since expanded to include three other milestones of robotic engineering - The Electric Man (1885), The Steam Man (1865), and the Automatic Man (exact date unknown). And while these Victorian marvels might have benefited from some more imaginative names, their exploits (from Antarctic exploration and circumnavigation to foiling train robberies) would put Honda's new robot ASIMO to shame. One can only imagine why so few of us know about these extraordinary machines today.

Unless, of course, it's because they never existed.

"When the philosophers of the eighteenth century made religion out to be an enormous error conceived by priests, at least they were able to explain its persistence by the interest the sacerdotal caste had in deceiving the masses. But if the peoples themselves have been the artisans of these systems of erroneous ideas, at the same time that they were their dupes, how has this extraordinary hoax been able to perpetuate itself throughout the course of history?"
—Emile Durkheim

The National Aeronautics and Space Administration is investing close to a million dollars in an obscure Russian scientist's antigravity machine, although it has failed every test and would violate the most fundamental laws of nature. The Patent and Trademark Office recently issued Patent 6,362,718 for a physically impossible motionless electromagnetic generator, which is supposed to snatch free energy from a vacuum. And major power companies have sunk tens of millions of dollars into a scheme to produce energy by putting hydrogen atoms into a state below their ground state, a feat equivalent to mounting an expedition to explore the region south of the South Pole.

Zeitgeist Films, distributor of the documentary Derrida, currently in limited release in select cities across the country, poses the following rhetorical question on its promotional website: What if you could watch Socrates, on film, rehearsing his Socratic dialogues? The insinuation, of course, is that Jacques Derrida, the contemporary French thinker sometimes called the "father of deconstruction" deserves to be mentioned in the same breath as the ancient Greek thinker sometimes called the "father of philosophy." This is true only insofar as a firecracker and a hydrogen bomb both go pop. Otherwise, the comparison is ludicrous.

In college, one of my closest pals earned his doctorate in philosophy while I somehow managed to avoid taking a single course in that subject. An amazing feat, especially when one considers that my university stint had a longer run than the musical "Cats."

But the slighting was no mere oversight. I simply had no desire to engage in heady rationalizations or investigations into the causes and laws underlying reality. Do too much of that? You risk sapping all the fun and sense of mystery from life. Some things, I explained to myself, are best left unexplained.

It's a philosophy I adhere to to this day.

BBC News Online's science editor, Dr David Whitehouse, himself a Moon author, explains why he thinks Nasa should have gone ahead with its controversial book idea on the lunar landings.

We all laughed when Alan Sokal wrote a deliberately silly
paper entitled "Transgressing the Boundaries: Towards a
Transformative Hermeneutics of Quantum Gravity", and managed
to get it accepted by a refereed journal of social and cultural
