So, who am I, anyway? I suppose a perusal of the links below will have to do for now. I'm an autodidact for the most part; so take everything I say with a grain of salt ;).

I like seeing diagrams for both physics and mathematical topics; it often helps clarify text that otherwise would have to resort to tortuous verbiage along the lines of "now, imagine that there's a rod connecting A and B, rotate it through the 4th dimension...". If you have an article that you think could use a diagram, let me know on my talk page.

$x^{2}+y^{2}=z^{2}$

Quotes

"The human astronaut is not able to look for the Great Wall on Earth. He's not able to philosophize on the meaning of life. He's focused on his job in front of him, which is not tripping over the television cable." "Buzz" Aldrin, Science News, 1994

"Sometimes we sit and read other people's interpretations of our lyrics and think, 'Hey, that's pretty good.' If we liked it, we would keep our mouths shut and just accept the credit as if it was what we meant all along." John Lennon

"Voice or no voice, the people can always be brought to the bidding of the leaders. That is easy. All you have to do is tell them they are being attacked, and denounce the pacifists for lack of patriotism, and exposing the country to greater danger." Herman Goering

"I believe in an open mind, but not so open that your brains fall out." Arthur Hays Sulzberger, publisher of The New York Times from 1935 to 1961

"Every month, including September 2001, the U.S. highway death toll exceeds fatalities in the WTC, Pentagon, and four downed airliners combined. Just like the New York City firefighters and restaurant workers, last September's auto crash victims each had families, friends, critical job responsibilities, and valued positions in their churches and communities. Their surviving children, also, were left without one parent, with shattered lives, and much poorer than the 9/11 victims' families, who were showered with 1.5 million dollars, per fatality, from the federal government alone. The 9/11 victims died from malicious terrorism, arguably compounded by poor intelligence, sloppy airport security, and other failed procedures we imagined were protecting us. While few of September's auto deaths resulted from malice, neither were they "natural" deaths: most also resulted from individual, corporate, and societal choices about road safety engineering, enforcement of driving-while-drunk laws, safe car design, and so on." Clark R. Chapman and Alan W. Harris, "A Skeptical Look at September 11th; How We Can Defeat Terrorism by Reacting to It More Rationally", Skeptical Inquirer

"Spiritualists have sometimes seen scientific explanations of NDE's as dull and reductionist. However, the exploration of the mind-brain interface is one of the most exciting adventures which humans have ever undertaken. The real reductionism lies in attempts to draw a mystical shroud over the NDE, and to belittle the substantial evidence in favour of an scientific explanation."
