Delta

Copyright © 2009 Ernest Bloom.

Delta, Δ, at least in chemistry,
Most often refers to heat, to introducing
Increasing thermodynamic chaos, usually at
Very high temperatures. But lower case delta,
δ, signifies change; that's all: smooth,
Continuous change from one state to
Another. We know intuitively about the
Three dimensions of space, and we infer
One dimension of time; melt them together,
Minkowski advises, into conceptually useful
Four-dimensional spacetime. Now objects
In motion in spacetime experience
Continuous changes in position (s) in
Unit time (t), or in other words, velocity (v) is
δs/δt. And when velocity itself changes over
Time, objects experience acceleration (a), or
δv/δt. Interestingly, our good friend Albert
Conceived how gravity is only a kind of
Acceleration arising from the curvature
Of spacetime.

There's something very funny about
Acceleration.
