Merry Newtonmass!

Posted by mattusmaximus on December 23, 2011

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  He worked out the fundamentals of calculus, though his work went unpublished for more than 30 years.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! :)

Bill O’Reilly Doubles Down on the Stupid: “How’d the Moon Get There?”

Posted by mattusmaximus on February 2, 2011

Recently, I’ve posted about how Fox News personality Bill O’Reilly displayed a great deal of scientific ignorance when he tried to argue that God exists because “we cannot explain the tides”.  Of course, scientists do know how the tides work (as astrophysicist Neil deGrasse Tyson states: it’s gravity from the Moon, duh); but rather than admit his error, Bill O’Reilly has decided to double down on the stupid.  Just watch this…

Once again, O’Reilly makes the all-too-common argument from ignorance, specifically the god-of-the-gaps argument. Of course, we actually do have scientific answers to many of the questions brought up by Mr. O’Reilly.  Let us examine some of his statements/claims… Read the rest of this entry »

Bill O’Reilly’s “Tides = God” Argument is Demolished by Neil deGrasse Tyson

Posted by mattusmaximus on January 29, 2011

As a humorous follow-up to my recent post called God, Gravity, and the Anti-Science Lunacy of Bill O’Reilly, I just wanted to share a hilarious clip from The Colbert Report with you.  In it, Colbert does a marvelous job of, in his satirical way, calling Bill O’Reilly to the carpet on his god-of-the-gaps argument when he says:

Now, like all great theologies, Bill’s can be boiled down to one sentence: “There must be a God, because I don’t know how things work!”

In addition, Stephen Colbert is surprised when astrophysicist Neil deGrasse Tyson drops by for a visit and explains why the tides actually work :)

God, Gravity, and the Anti-Science Lunacy of Bill O’Reilly

Posted by mattusmaximus on January 7, 2011

Oh man.  As a high school & college physics professor, I have to say that I’ve heard some pretty bad arguments regarding physics in my day, but I think this one is worth a mention: Fox News celebrity Bill O’Reilly displays his gross ignorance of basic physics by… well, by ignoring gravity.

Bill O’Reilly on Science: You Can’t Explain the Tides

Apparently, Bill O’Reilly has never heard of the moon. In a debate Tuesday with Dave Silverman, head of the American Atheist group behind this, the Fox host tried to prove the existence of God by citing the unknowable mysteries of the tides. “I’ll tell you why [religion is] not a scam, in my opinion,” he told Silverman. “Tide goes in, tide goes out. Never a miscommunication. You can’t explain that. You can’t explain why the tide goes in.” …

Yup, he’s ignoring gravity and replacing it with God.  Just watch the video for yourself (the relevant part begins at the 1:40 mark)…

Wow… just, wow.  Apprently, Mr. O’Reilly has never studied the universal law of gravitation (which is standard in any high school physics class) which explains quite clearly – without any mention of God, Zeus, Thor, or Santa Claus – where tidal forces come from.  Essentially, tides in Earth’s oceans exist because one side of our planet is closer to the Moon (or the Sun, both exert tides) than the other.  Thus, the side closer to the Moon (Sun) is pulled slightly more than the side further away from the Moon, resulting in the tidal bulges which lead to the rising and falling of the oceans.  This article on Wikipedia (ever heard of Google, Mr. O’Reilly?) and graphic can help illustrate the point I’m making:

Graphic of tidal forces; the gravity field is generated by a body to the right. The top picture shows the gravitational forces; the bottom shows their residual once the field of the sphere is subtracted; this is the tidal force. Source: Wikipedia

Essentially, O’Reilly is making a stunningly stupid argument from ignorance (in this case known as the god-of-the-gaps) by saying that just because he doesn’t know how the tides work, then that must mean that his version of God is real.  Of course, it might be interesting to ask Mr. O’Reilly’s feelings on the matter after he’s had a lesson in basic physics – would he then conclude that the tides are evidence against the existence of God?  That precarious position is precisely why serious theologians & philosophers do not engage in arguing from ignorance.

Such ham-fisted arguments are also why natural science separated itself from supernatural causes back in the 19th century as natural philosophy transitioned into what we now call modern science.  It seems that O’Reilly is still stuck in the 1800s.

In closing, despite my atheism, if Mr. O’Reilly or anyone wants to believe in God, that’s fine by me I suppose, just so long as they don’t piss all over science in the process.
