"What Politicians Do to Our Kids" from "DavidHogg111"




David Hogg made a great 23-minute live video of how he and a friend set up a “die in” early this morning at a Publix store in south Florida. 

The best name for this video is “What Politicians Do to Our Kids” (which is actually a shorter video on another tweet).


The demonstrations worked.  Publix has suspended contributions to an NRA-backed politician in Florida, Adam Putnam.

Nassim Taleb would say such politicians don't have their own "skin in the game". 

So maybe Hogg is now the NRA’s worst nightmare.  He is quick-witted and articulate and can outmaneuver right-wing zealots who fall for his honeypot.
  
In Oklahoma City today, a mentally ill man shot three people in a restaurant, but two “good Samaritans” killed the suspect and prevented a cranage.  Is this a “good guy with a gun” scenario?

There was an incident in a middle school in Indiana today, and a science teacher was the hero.

"Why Do We Boil Lobsters Alive?" Even at home!




Tech Insider asks “Why Do We Boil Lobsters Alive?” Ask a cooking school. 


Turns out it is because a dangerous bacteria that is hard to remove with cooking grows quickly after the lobster’s death.

But can lobsters feel pain?  They are arthropods.  Like insects.

Switzerland and New Zealand have outlawed the practice.

I can remember a friend who moonlighted at the Giant in the early 1970s, and one time when I went to meet him there he was tending to the lobsters  (In DADT III book chapter 2).
  
Yorgos Lanthmos (“The Lobster”) would approve.

"Could You Land on Jupiter?"



Could You Land on Jupiter?” (or “What Would Happen if Humans Tried to Land on Jupiter? (4-1/2 min) , from Tech Insider, gives us an almost definitive animated look at what the rapidly increasingly dense layers of Jupiter’s atmosphere look like a fictitious astronaut passes through them.


The pressures and particularly temperatures get hotter than the surface of the Sun. 


Eventually you get to a layer of metallic hydrogen (rather like mercury) where you bobble up and down.  The illustration of what you might “see” is indeed interesting.

Patreon has a similar video “What Would Happen If You Fell into Saturn?” (8 min).  Saturn, while smaller, still probably has the metallic hydrogen layer, and everything dissolves in it.

This is not the same video about Jupiter's internals as Joe Scott's on Sept. 24, 17.

"What Will It Take to Stay Healthy in Space? Practical Artificial Gravity": short


“What Will It Take to Stay Healthy in Space?: Practical Artificial Gravity” (with Fraser Cain).


Cain takes up the O’Neill Cylinder, but also looks at the idea of smaller centrifuges for astronauts to spend time in.

Differential gravity, where you feel more gravity in your feet than head, causes nausea.
Astronaut Scott Kelly could not walk or function very well for several hours after he got off the space station when it landed.  Exercise alone would not do the trick.

What happens when you stand still inside an O’Neill Cyclinder habitat and drop an object?  What happens if you try to play baseball?

The film says you need at least 20% Earth’s gravity on a moon to function well.
  
Titan’s gravity is only 14% of Earth’s, because it is not very dense.  For Mars it is 38%.

"Two Faces": German short film looks at "unit cohesion" of a soccer team with a gay player



Two Faces” (“Zwei Gesichten”), 2014, directed by Christian Slater, is a 22-minute short about a soccer player coming out as gay, eventually to his team.


Jonathan (David Bruckner) has been dating Hannah, who is being to suspect because of his inattentiveness.  Pretty soon the team starts to wonder, and some intolerance breaks out toward the end.

There is some reassurance during the closing credits.Yet, 2014 sounds rather late for this to be an issue in Germany. 

In the middle of the film, the coach talks about unit cohesion for the team, playing as one man.  Sound familiar?

"The Celluloid Closet": When did Hollywood get comfortable with homosexuality?


I do barely recall seeing the 1995 documentary “The Celluloid Closet” (Sony Pictures Classics), by Rob Epstein and Jeffrey Friedman, about LGBT actors (actresses) and gay characters in cinema (right off the bat, the 1993 film “Philadelphia” about AUDS comes to mind).The movie came out (pun) about the time I started working on my first book. 


The closet door was getting pretty transparent by the time Clinton took office, which could have helped push the debate on gays in the military.  “Serving in Silence” and “Coming Out Under Fire” and “Any Mother’s Son”.


“Cat on a Hot Tin Roof” and “Suddenly Last Summer” get excerpted, as well as the love-in at the end of “Spartacus”.
 
The complete film can be rented on YouTube for $2.99.
  
The two directors recently did an award winning short about a hospice, “End Game”.

"Faking Gravity in a Spaceship": Let's start learning how artificial g's really work



Faking Gravity in a Spaceship” (4 minutes) is a typical YouTube video showing how artificial gravity would work for inhabitants of a rotating space station.
  

Asa you climb a ladder you feel “lighter”(until you reach the center, where you feel nothing).  As you run faster you may feel “heavier”.
  
What I wanted to see is what happens if you drop something. It would seem to more horizontally, I think/  What happens when you pour coffee for dinner?
  
The video does mention the Coriolis effect.
