One Hundred Interesting Mathematical Calculations, Number 7 One Hundred Interesting Mathematical Calculations, Number 7: Julius Caesar's Last Breath What's the chance that the breath you just inhaled contains at least one air molecule that was in Julius Caesar's last breath--the one in which he said (according to Shakespeare) " Et tu Brute ? Then die Caesar"? Assume that the more than two thousand years that have passed have been enough time for all the molecules in Caesar's last breath to mix evenly in the atmosphere, and that only a trivial amount of the molecules have leaked out into the oceans or the ground. Assume further that there are about 10 44 molecules of air, and about 2 x 10 22 molecules in each breath--yours or Caesar's. That gives a chance of 2 x 10 22 /10 44 = 2x 10 -22 that any one particular molecule you breathe in came from Caesar's last breath. [1-2x10 -22 ] [2x10^22] How to evaluate this?

"Quantum Physics, Consciousness, Creativity, and Healing" with Amit Goswami (part 1 of 3) | IONS Library
Visionary: Amit Goswami Part 1 | Part 2 | Part 3 In this 3-part audio presentation, Dr. Goswami provides a lucid explanation of three fundamental principals of quantum physics, laying the groundwork for a mind-expanding look at how they relate to consciousness, creativity, and healing. With clear definitions he contrasts the quantum principals with traditional scientific beliefs, and then provides examples from research and human experience to demonstrate their veracity. The building blocks to this comprehension are straightforward: Everything is comprised of waves of possibility at the subatomic level. In Part 1 Dr. Download as mp3 Publication Date: Length:

The threads on the jeans then will very effectively both fix any tiny bends in the blades that inevitably happen and will also sharpen the blades on your shaver cartidge. 2) How to make your teeth whiter Baking soda makes a good teeth whitener. 1.

World's funniest joke
The "world's funniest joke" is a term used by Richard Wiseman of the University of Hertfordshire in 2002 to summarize one of the results of his research. For his experiment, named LaughLab, he created a website where people could rate and submit jokes.[1] Purposes of the research included discovering the joke that had the widest appeal and understanding among different cultures, demographics and countries.[citation needed] The History Channel eventually hosted a special on the subject.[citation needed] The jokes The winning joke, which was later found to be based on a 1951 Goon Show sketch by Spike Milligan,[2] was submitted by Gurpal Gosal of Manchester: Two hunters are out in the woods when one of them collapses.
