“Whether humans are responsible for the bulk of climate change is going to be left to the scientists, but it’s all of our responsibility to leave this planet in better shape for the future generations than we found it.” -Mike Huckabee It only makes sense that scientists should debate and argue over the findings in…

“Time travel used to be thought of as just science fiction, but Einstein’s general theory of relativity allows for the possibility that we could warp space-time so much that you could go off in a rocket and return before you set out.” -Stephen Hawking As always, there’s been a new fantastic week of articles here at…

“One of the great things about music is that it has the capability of time travel – you smell a certain smell in the room and it takes you back to your childhood. I feel like music is able to do that, and it happens to me all the time.” -M. Ward Have you ever…

“The experiments that we will do with the LHC [Large Hadron Collider] have been done billions of times by cosmic rays hitting the earth. … They’re being done continuously by cosmic rays hitting our astronomical bodies, like the moon, the sun, like Jupiter and so on and so forth. And the earth’s still here, the…

“I was always amused when overtaking one of these great monsters [a tortoise], as it was quietly pacing along, to see how suddenly, the instant I passed, it would draw in its head and legs, and uttering a deep hiss fall to the ground with a heavy sound, as if struck dead. I frequently got…

“It appears, from all that precedes, reasonably certain that if there be any relative motion between the earth and the luminiferous ether, it must be small; quite small enough entirely to refute Fresnel’s explanation of aberration.” -Albert A. Michelson In the 1880s, it was clear that something was wrong with Newton’s formulation of the Universe.…

“In recent years several new particles have been discovered which are currently assumed to be “elementary,” that is, essentially structureless. The probability that all such particles should be really elementary becomes less and less as their number increases. It is by no means certain that nucleons, mesons, electrons, neutrinos are all elementary particles.” -Enrico Fermi…

“We must regard it rather as an accident that the Earth (and presumably the whole solar system) contains a preponderance of negative electrons and positive protons. It is quite possible that for some of the stars it is the other way about.” -Paul Dirac You might think that the proton, made up of three spin=1/2…

“You couldn’t be here if stars hadn’t exploded, because the elements – the carbon, nitrogen, oxygen, iron, all the things that matter for evolution and for life – weren’t created at the beginning of time. They were created in the nuclear furnaces of stars, and the only way for them to get into your body…

“Entropy shakes its angry fist at you for being clever enough to organize the world.” -Brandon Sanderson The universe was born hot, dense, expanding, full of matter, antimatter and radiation… and in a low-entropy state. If entropy is a measure of disorder, though, that sure does sound like an awfully high-entropy state, not a low-entropy…
