It’s almost December 25th, and while some people are celebrating certain holidays (Dies Natalis Solis Invicti!), one thing I like to do is take a little time to recognize one of the greatest contributors to modern science: Sir Isaac Newton. Newton was born on December 25th, 1642 (according to the old-style Julian calendar)…
I totally stole this image from Skeptico 🙂
Isaac Newton was an English physicist and mathematician. The son of a yeoman, he was raised by his grandmother. He was educated at Cambridge University (1661-1665), where he discovered the work of Rene Descartes. His experiments passing sunlight through a prism led to the discovery of the heterogeneous, corpuscular nature of white light and laid the foundation of physical optics. He built the first reflecting telescope in 1668 and became a professor of mathematics at Cambridge in 1669. He worked out the fundamentals of calculus, though his work went unpublished for more than 30 years. His most famous publication, The Principia Mathematica (1687), describes his works on the laws of motion (now named for Newton), orbital dynamics, tidal theory, and the theory of universal gravitation, and is regarded as the seminal work of modern science. He was elected president of the Royal Society of London in 1703 and became the first scientist ever to be knighted in 1705. During his career he engaged in heated arguments with several of his colleagues, including Robert Hooke (with whom he argued over authorship of the inverse-square relation of gravity) and Gottfried Leibniz (over the authorship of calculus).
Of course, while Newton was certainly no saint (he had a reputation for being kind of a nasty guy, especially to his academic opponents, and he also dabbled in alchemy, Biblical numerology, divination, the occult and many other things we’d consider quite woo-ish today), we can see from his accomplishments listed above just why he is regarded as one of the greatest scientists of all time, and it is for those contributions to humanity that we remember him.
So this December 25th, take some time to raise a glass, and perhaps admire a falling apple, to toast Isaac Newton and his legacy. Cheers! 🙂

You know, there are days when I think I’ve seen it all. I think to myself: “there are some things which are just too stupid, crazy, and/or ‘out-there’ that nobody will attempt to believe & defend.” And then something like this crosses my email inbox: an actual conference, titled “Galileo Was Wrong: The Church Was Right”, which attempts to seriously argue for… get this… geocentrism. You know, geocentrism – the idea that the Earth is the center of the universe. You know, geocentrism – the notion which has become, and deservedly so, synonymous with the Dark Ages & all manner of backward and nonsensical thinking. You know, geocentrism – the completely defunct idea which even the modern Catholic Church itself has admitted as having no merit whatsoever! Yeah, that geocentrism…
Actually, before I facepalm myself into a state of blissful unconsciousness over the incredible level of stupidity embodied by this conference, allow me to seriously address the entire question of geocentricity. I wish to do so because of two reasons: 1) if these pseudoscientists are holding a conference, they are attempting to get more media attention and must thus be countered; and 2) it seems that a whopping 18% of people in the United States actually believe the Earth is the center of the universe (which is far too many)! So here goes…
First off, I’m going to hit just a few major points in this post. If you want a much more thorough treatment of this topic, go see Phil Plait’s post over at Bad Astronomy; and if you are interested in reading more about the history of geocentric models of the universe, I suggest you check out Wikipedia as a starter.
Now, let me begin by saying that if you don’t have any education at all in the topic of Earth & space science, astronomy, physics, and what-have-you that I can understand an almost blind acceptance of geocentrism for one simple reason: it certainly appears that everything in the sky moves around the Earth. Look in the sky and you’ll see the Sun, Moon, planets, stars, etc all moving – from your frame of reference – around the Earth.
Of course, a little more thought, along with a deeper analysis of astronomical data, will show that the geocentrism as mentioned by these “Galileo Was Wrong” goofballs is totally bogus…

When I was at The Amazing Meeting 7 in Las Vegas recently, I participated in the first TAM Talent Show. My skit focused upon a favorite physics demonstration and gave me an excellent opportunity to teach some skepticism: the Bed of Nails. Having performed this demonstration about 40-50 times throughout my teaching career, I decided it was time to take things to the big stage 🙂
The demonstration is simple, and dangerous – IT SHOULD NOT BE ATTEMPTED WITHOUT PROPER SUPERVISION!!! In it, I lay down upon a bed of nails, have a second bed of nails placed atop my stomach & chest, have a concrete cinder block placed atop that, and – last but not least – have an assistant break the block with a 10-lb sledgehammer! Here’s some slow motion footage of the demo at the TAM Talent Show…
Moments later, I got up off the bed of nails with no damage at all – pretty impressive stuff! Here’s a photo of my chest seconds after the demo…
The bed of nails has a history of woo – there are some in the martial arts community who claim that their chi or “life force” protects them from injury. Others, such as gurus in India, claim that the only reason they are uninjured is because of the specific type of meditation they perform. But a simple application of Occam’s Razor is all that is necessary to explain what’s going on here – and it doesn’t have anything to do with chi, mysticism, or anything supernatural.
