It’s Geek Week On YouTube!

Posted by Dan Satterfield

In honor of geek week on YouTube, and (so that you do not have to wade through all the crazy NASA, HAARP, and Chemtrail crazies) I thought I might post a selected number of really cool videos. Number one on the hit parade is Veritasium’s six-minute fantastic explanation of how a transistor works!

Am I the only one who finds it amazing that a political world-view can cause someone whose never taken a college physics class to tell nearly every expert on atmospheric physics they are wrong?? Fortunately the brain somehow blocks the realization of how ridiculous they seem to everyone who is not living in their bubble. Am reading a fantastic book on the psychology of this right now and highly recommend it.

Just to be clear, EVERY claim that Lutz makes in the video below is factually incorrect. No one has forecasted the Florida Keys to go underwater in this century, and Earth is not cooling (It’s warming faster than ever). Oh, and almost all of the forecasts of the science community have been too conservative. Arctic Sea ice of course is the worst case; it’s going away much faster than predicted a decade ago. This clip reminds me of the old saying that you are entitled to your own opinion, but not your own facts.

Tyson is at his best when he makes you think about something that perhaps you had never even realized before. In 1000 AD the scientific center of the Universe was Baghdad. Tyson explains why it’s not been in 900 years.

The video below is not showing you satellite imagery. It’s a model that spins up clouds and storms by telling it how much radiation we are getting from the sun! A great example of how sophisticated numerical weather and climate prediction is now using supercomputers.

Last but not least:
