Daylight Saving Time is Upon Us


Daylight Saving Time is upon us tonight - Sunday, March 12th, 2017 at 2am.  Don't forget to turn your "non-smart" clocks forward an hour.

I like to remind myself with, the following which helps me remember which direction to turn the clocks to.

"Spring" forward into action, and "Fall" back to sleep.

Why Fundamental Forces Are Difficult To Explain



Richard Feynman was asked Why Magnets Repel Each Other?  His answer sums up why it is so difficult to explain physics.  It requires accepting other answers as truth, or you rabbit hole down an endless path of why questions.  We take for granted that when your hand pushes against a chair it moves.  But your physical hand never actually touches the chair.  The electrical forces repel the chair at a minuscule level.  The magnetic force is very similar to the electrical forces.  The iron atoms of a magnet are all lined up so the magnetic forces are amplified to where they cross a greater distance.
