“There are several categories of scientists in the world; those of second or third rank do their best but never get very far. Then there is the first rank, those who make important discoveries, fundamental to scientific progress. But then there are the geniuses, like Galilei and Newton. Majorana was one of these.” -Enrico Fermi…

“If you’re puzzled by what dark energy is, you’re in good company.” -Saul Perlmutter We normally assume that the fundamental constants of the Universe are actually constant, but they don’t have to be that way. They could vary in space, in time, or with the energy density of the Universe, in principle. Before believing in…

“Oh Beautiful for smoggy skies, insecticided grain, For strip-mined mountain’s majesty above the asphalt plain. America, America, man sheds his waste on thee, And hides the pines with billboard signs, from sea to oily sea.” -George Carlin When you think of helium, you very likely think of balloons, birthday parties, and blimps. But this inert,…

“At least six lamp posts were snapped off while I watched. A few minutes later, I saw a side girder bulge out. But, though the bridge was bucking up at an angle of 45 degrees, I thought she would be able to fight it out. But, that wasn’t to be.” -Bert Farquharson If you’ve only ever…

“I don’t always bet the same way I talk. Good advice is one thing, but smart gambling is quite another.” -Hunter S. Thompson Did you know the world’s first wearable computer was built all the way back in the 1960s, was worn on your feet… and was used to help gamblers cheat at roulette? Physicists…

“My discovery that black holes emit radiation raised serious problems of consistency with the rest of physics. I have now resolved these problems, but the answer turned out to be not what I expected.” -Stephen Hawking One of the most puzzling things about Black Holes is that if you wait around long enough, they’ll evaporate…

“It was quite the most incredible event that has ever happened to me in my life. It was almost as incredible as if you fired a 15-inch shell at a piece of tissue paper and it came back and hit you.” -Ernest Rutherford Nuclear physics has, for decades now, been regarded less as a window…

“Logic takes care of itself; all we have to do is to look and see how it does it.” -Ludwig Wittgenstein There are a great many events that occurred to give rise to the world, the Universe, and you. Everything from the Big Bang to the existence of the laws of physics to the cosmic…

“…an understanding of the infinite tree of universes seems to be needed in order to make statistical predictions about the properties of our own universe, which is assumed to be a typical “branch” on the tree.” -Alan Guth The Big Bang is commonly regarded as the start of it all, but that’s only the birth…

“When we have found how the nucleus of atoms is built up we shall have found the greatest secret of all — except life.” -Ernest Rutherford What does the future of astrophysics look like? Have we already made all of the fundamental discoveries we’re going to make? Is the rest just categorization of objects, identification…
