CNN: Aerial view of Mexico Beach, FL after Hurricane Michael



The most grave damage from Hurricane Michael was at Mexico Beach, a bit East of Panama City, FL


There’s another video made as the hurricane passed.

Again, I’m lucky enough to have lived in relatively lower risk areas from floods, hurricanes, tornadoes, and wildfires.

But somebody has to live there.

But should public policy encourage people to live “on the beach” and do nothing about climate change? Trump, again.  However, some new construction on pilings did survive 155 mph winds sustained.  That is possible if you spend enough money on metal construction.
  
This hurricane maintained wind strength on land, into GA and S.C., much longer than most do.

Why in physics, "weaklessness" might not be such a good thing for existence



Why the Weak Nuclear Force Ruins Everything” on Sci-Show. This is a little different from most posts on this blog.  It's only a hypothetical risk. 


Of the four major forces, the weak nuclear force is the only one to violate spin symmetry laws and to treat anti-matter and matter differently.

Some physicists have proposed some alternate universes might be “weakless” – which would mean no radioactivity and no decay of elements, and no nuclear weapons.

That means no North Korea’s.  But it might also mean that since matter and anti-matter would cancel out, there would be no universe at all.

So in physics, ideological equality, however correct politically, isn’t always what you want.
