myelination seems to increase with practice, suggesting that the insulation and repetitive use of our neurons play an important role in the development of expertise. (This is what's known as muscle memory.)

The past and future are equally real. This isn't completely accepted,
but it should be. Intuitively we think that the "now" is real, while
the past is fixed and in the books, and the future hasn't yet
occurred. But physics teaches us something remarkable: every event in
the past and future is implicit in the current moment. This is hard to
see in our everyday lives, since we're nowhere close to knowing
everything about the universe at any moment, nor will we ever be — but
the equations don't lie. As Einstein put it, "It appears therefore
more natural to think of physical reality as a four dimensional
existence, instead of, as hitherto, the evolution of a three
dimensional existence."
