“Our external environment no longer seems to have any firm boundaries, any limits, or any positive cues about when to stop consuming anything. I mean, there is a reason that people get fat — it’s easy and cheap to get high-calorie, tasty food.” –Bob Harper There are plenty of good things we can all do to get…

“If everything was perfect, you would never learn and you would never grow.” –Beyoncé As human beings, we may be far from perfect. Even our mathematical celebrations, like Pi Day, are mere approximations. But there are a few mathematical quantities out there that really are perfect. And today, June 28th, I’d like to share with you…

“So here we have π squared, which an engineer would call ‘10.’” –Frank King This March 14th, stump your friends with these amazing facts about the world’s favorite transcendental number! I’ve written about Pi Day twice before here on Scienceblogs, but for this year’s festivities, I’ve assembled a collection of my favorite facts about everyone’s…

“There is not enough love and goodness in the world to permit giving any of it away to imaginary beings.” -Friedrich Nietzsche You know that the square root of -1 is “i”, an imaginary number. But did you know any of these? For classical (Newtonian) mechanics, as well as electromagnetism, it’s sufficient to use real mathematics…

“There are three hundred and sixty-four days when you might get un-birthday presents, and only one for birthday presents, you know.” -Lewis Carroll It’s the end of the week once again, and so it’s time for yet another Ask Ethan column! This week, I was asked a wonderful math question by Keith H., who wanted to know: Among…

“By denying scientific principles, one can maintain any paradox.” –Galileo Galilei Day and night. It seems like the simplest, most natural thing about our world, that the Sun illuminates one half of the Earth at a time. While the Earth spins on its axis, orbiting the Sun, roughly half of our lives are spent bathed…

“There are some things we do much better than computers, but since most of chess is tactically based they do many things better than humans. And this imbalance remains. I no longer have any issues. It’s a bit like asking an astronomer, does he mind that a telescope does all the work?” –Vishy Anand It…

“Arithmetic! Algebra! Geometry! Grandiose trinity! Luminous triangle! Whoever has not known you is without sense!” –Comte de Lautréamont When you think about it, it’s amazing that our physical Universe makes sense at all. The fact that we can observe what’s happening, determine the laws that govern it, and predict what will happen under the same…

“If a ‘religion’ is defined to be a system of ideas that contains unprovable statements, then Gödel taught us that mathematics is not only a religion, it is the only religion that can prove itself to be one.” –John Barrow Image is from the front cover of the most important medieval picture bible to survive.…
