I choose to portray myself as an anonymous entity because I believe that it prevents any distractions from the arguments I make, the concepts I debunk, and the ideas I propagate. All you need to know about me is that I support the progression of the human race to help build a better world.I enact this by assisting in the propagation of good ideas, and the destruction of bad ones.

The history of film in one scene

"This film is looking a little too Japanese."

"It’s set in Heian era Japan."

"So what are you trying to say?"

"That black people haven’t been invented yet?"

"This film is looking a little too white."

"It’s set in prehistoric France during the time of the Cro-Magnons."

"So what are you trying to say?"

"This film is looking a little too Latin."

"It’s set in Tenochtitlan."

"So what are you trying to say?"

Suppose you had a single hydrogen atom and at a particular instant plotted the position of its electron. Soon afterwards, you do the same thing, and find that it is in a new position. You have no idea how it got from the first place to the second. You keep on doing this over and over again, and gradually build up a sort of 3D map of the places that the electron is likely to be found.
The Heisenberg Uncertainty Principle  says - loosely - that you can’t know with certainty both where an electron is and where it’s going next. That makes it impossible to plot an orbit for an electron around a nucleus, but we have a mathematical function that describes the wave-like behavior of either one electron or a pair of electrons in an atom. This function can be used to calculate the probability of finding any electron of an atom in any specific region around the atom’s nucleus.
In the hydrogen case, the electron can be found anywhere within a spherical space surrounding the nucleus. Such a region of space is called an orbital. Orbits and orbitals sound similar, but they have quite different meanings. It is essential that you understand the difference between them. You can think of an orbital as being the region of space in which the electron lives. The GIF animation shows the probability densities for the electron of a hydrogen atom in different quantum states. These orbitals form an orthonormal basis for the wave function of the electron. These shapes are intended to describe the angular forms of regions in space where the electrons occupying the orbital are likely to be found.

Higher Dimensions from String Theory

String Theory predicts the existence of more than the 3 space dimensions and 1 time dimension we are all familiar with. According to string theory, there are additional dimensions that we are unfamiliar with because they are curled up into tiny complicated shapes that can only be seen on tiny scales. If we could shrink to this tiny, Planck-sized scale we could see that at every 3D point in space, we can also explore 6 additional dimensions. This animation shows a Calabi-Yau surface which is a projection of these higher dimensions into the more familiar dimensions we are aware of.

Brian Greene’s book, The Elegant Universe, was made into a documentary and has a chapter that does a good job of explaining this concept. The Elegant Universe [documentary]
