“To be loyal to myself is to allow myself to grow and change, and challenge who I am and what I think. The only thing I am for sure is unsure, and this means I’m growing, and not stagnant or shrinking.” ‐Jarod Kintz But for the Universe, although it’s constantly changing, growing in a gravitational sense…

There are a few questions that have perplexed humans for all of recorded history, ranging from the nature of matter to the origin of the Universe to whether there are limits to what is knowable in principle about all there is. One of the great questions that people have wondered about since ancient times — that…

Every once in a while, a scientist comes along who leaves an impression on the field so strong that all of the subsequent work on uses their results as a starting point, as a foundation. Einstein did that with relativity; Dirac did that with relativistic quantum mechanics; even Newton did that with mechanics. But what about…

“The atoms come into my brain, dance a dance, and then go out — there are always new atoms, but always doing the same dance, remembering what the dance was yesterday.” -Richard Feynman It took 13.8 billion years of cosmic evolution, billions of years of biological evolution and astronomical numbers of events unfolding exactly as they have…

“By allowing the positive ions to pass through an electric field and thus giving them a certain velocity, it is possible to distinguish them from the neutral, stationary atoms.” -Johannes Stark One of the simplest tenets of electromagnetism — the second of the fundamental forces ever discovered — is that charged particles are accelerated parallel to electric…

“Concentrate all your thoughts upon the work at hand. The sun’s rays do not burn until brought to a focus.” -Alexander Graham Bell The Sun, contrary to what you might normally think about it, isn’t a constant, uniform source of radiation. It has an active surface, replete with temperature variations, sunspots, and occasionally a large…

“Art has a double face, of expression and illusion, just like science has a double face: the reality of error and the phantom of truth.” -Publilius Syrus Out in the depths of space, objects range from the incredibly small and low mass to the huge and super-heavy, shrinking down again for the most ultra-massive objects…

“Trust yourself. Create the kind of self that you will be happy to live with all your life. Make the most of yourself by fanning the tiny, inner sparks of possibility into flames of achievement.” -Golda Meir If you’ve never seen the glorious, athletic spectacle that is Sasuke (Ninja Warrior), you are missing out on…

The Two Faces of the Moon (Synopsis)

“When you’re finally up at the moon looking back on earth, all those differences and nationalistic traits are pretty well going to blend, and you’re going to get a concept that maybe this really is one world and why the hell can’t we learn to live together like decent people.” -Frank Borman, Apollo 8 You’ve…

“What we observe is not nature itself, but nature exposed to our method of questioning.” -Werner Heisenberg You might think there are few sacred quantities when it comes to matter: properties that are so fundamentally inherent that even the weirdness of quantum mechanics can’t touch them. But the quantum nature of the Universe will have none…
