“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…

“There is a fifth dimension, beyond that which is known to man. It is a dimension as vast as space and as timeless as infinity. It is the middle ground between light and shadow, between science and superstition.” -Rod Serling If we take a look at a two-dimensional surface, it’s pretty apparent that we’re pretty…

“I do have a blurred memory of sitting on the stairs and trying over and over again to tie one of my shoelaces, but that is all that comes back to me of school itself.” -Roald Dahl Most of us learn to tie our shoes when we’re very young, go through life tying it through…

“I would like nuclear fusion to become a practical power source. It would provide an inexhaustible supply of energy, without pollution or global warming.” -Stephen Hawking Climate science is a hotly debated area, with many disputing the robustness and ethical motivations of the scientists in the field. But even if you throw everything we know…

“There is a fine line between censorship and good taste and moral responsibility.” -Stephen Spielberg Another week full of amazing science stories has gone by here at Starts With A Bang, and there are some fun and fantastic announcements! We welcomed a new contributor, Jess Shanahan, to our ranks; I found out that Forbes has…
