Day 219 - An Evening with Neil deGrasse Tyson

May 12, 2011
A view from beyond Saturn, showing an eclipse of the Sun.
Near Earth Objects (NEO) = Killer Asteroids
-Asteroid size of the Rose Bowl scheduled to hit earth on April 13th 2036 
(It's a Friday)
-Named for Egyptian god of darkness – Apophis
-1 in 10 chance of hitting us (Wikipedia doesn't buy this number.  I'm not sure who to believe: A world-renowned Astrophysicist, or a guy living in a basement.)
-Impact would cavetate (sp?) the ocean creating a tsunami, ocean fills the whole, force of water filling hole creates splash, which creates another tsunami.  This sequence would happen 40 times.
-Can predict this down to the minute
-Russia invited Tyson to help tow Apophis.  But NASA didn't.
-Little Prince (French Children's Story).  In the story, the Prince hails from Asteroid B612, which is now a group dedicated to deflecting asteroids.

Dark Matter and Dark Energy
“We are dumb stupid about Dark Matter and Dark Energy”
Universe expanding which contradicts gravity = Dark Energy
Multiverse – Just like the Jet Li movie “The One”
Dark Matter might be ordinary matter in an adjacent universe

Pluto
Our moon is 5 times the mass of Pluto.  This is one reason why Pluto sucks as a planet.  Tyson explained he received a huge negative backlash from his push to declassify Pluto as a planet.  A kid wrote him this letter:
"Why can't Pluto be a planet?  If it's small doesn't mean that it doesn't have to be a planet anymore.  Some people like Pluto.  If it doesn't exist then they don't have a favorite planet.  Please write back, but not in cursive because I can't read in cursive."

Influence of Islam
W quote “Our God is the God who named the stars”
Two thirds of stars have Arabic names
Why?  Islamic Golden Age from 800 – 1100
Hamid al – ghazali interprets the Quran for people.  Claims math is the devil.
3/609 nobel prizes given to muslims between 1900-2010

And he's funny:
The French don’t even have a word for entrepreneur.
Black Hole – first ever color image

Bad Physics:
Holiday Inn offers bed heaters (people) who are fully clothed, thus fully insulated, thus do not transfer heat.

Math ignorance:
“I’ve changed my views 360 degrees on that issue”
(Maybe this was a clever way of saying you have not changed your mind?)
“Half the schools are below average”
(That's how averages usually work)
“80% of crash survivors studied the locations of the exit doors before takeoff”
(100% of victims could have studied the locations of exit doors)
Thanks, Neil!!
