Is Climate Change Just A Lot Of Hot Air?
Perhaps you amateur climate scientists could pay attention to the what the scientists say that study this issue. The consequences are serious. The effects are starting now. There are many positive feedback loops. We are driving the climate to a state it has not been in for the past several million years. (Oh, and that 'atomic bomb per second' is about 280kt/s these days.)
The Newsroom's Take On Global Warming-Fact Checked
The well-funded campaign to cast doubt on climate change science has very little imagination. They simply accuse scientists of what they do - distorting data for financial gain to please some powerful interests. The fossil fuel industry does this every day. The expanding global community of scientists, in many disciplines, with ~100,000 research projects, does not. The effects of climate change are already being felt. For example, tens of thousands are dying in Bangladesh from increased flooding and storms. The difference now is that leaders in Bangladesh, and people around the world, are blaming this on the history of greenhouse gas emissions - dominated by the US. (China is a new contributor, most of the historical emissions have come from the US.) Bangladesh is now expecting numbers of climate refugees in the 10s of millions in coming decades. Around the world, the refugee crisis could easily exceed that of the 50M during WWII. And they will know who to blame.

It can be different. Look at the prison system in scandinavian countries.

Doodling in Math Class: Triangle Party
I was lucky enough to be shown this kind of playing with math when I was young, and it sustained me through careers in science and engineering. From what I hear about current education, all the fun stuff has been pushed out of the classrooms today by 'teach the basics' fanatics.
Spiral Galaxies - Sixty Symbols
Here is a nice simulation of a spiral galaxy with the stars going through the spiral density wave..

Richard Feynman - My Favourite Scientist
Thanks to VideoSift users over the years, that video tag "Richard Feynman" brings up dozens of examples of Feynman's stories and interviews. I had not heard his 'hungry philosophers' one before.. :-)
How a Train Stays on a Track (not as simple as you thought)
Richard Feynman has many wonderful explanations and stories. I recommend:
"Classic Feynman" (a combined and expanded version of "Surely You're Joking, Mr. Feynman!" and "What Do You Care What Other People Think?")
http://www.amazon.com/Classic-Feynman-Adventures-Curious-Character/dp/0393061329/
For the real physicists out there, there is the book "Genius" which combines biographical info with descriptions of his theories and nobel prize winning work.
