Holiday Physics Card, 2016

Just put them in the mail on December 24...It was a fun year of thinking, whether the idea is right...

Trying to be a semi-pro amateur physicist (yes I accept special relativity is right!). I _had_ my own effort to unify gravity with other forces in Nature. It ran into quite a number of technically... Read More »

Another year, another card inspired by what I am thinking about in physics.




Inside the card it reads...

Time is not space,

[note: this blog, as written is insufficient. I will need to provide an action to clarify the nature of the proposal.]


Classical gravity is not good enough.  As a first step, one must think about groups since that is the foundation of the Standard Model of physics.

I have decided to rescind this proposal.  Stars in a galaxy travel at one velocity, light at the speed c.  There is only one velocity involved in applying the product rule to the definition of a force as a change in momentum.  Note that is not a trivial application of the product rule either.  Newton's second law is invariant under Galilean transformation.  The dm/dt dR/dt is not invariant.

The Problem with Velocity Profiles


My 20+ year tradition of a physics inspired holiday card continues.  My friends like them, even if they are not understood :-)
