Burning carbon-based substances like oil, gas, and especially coal, produces billions of tons of extra carbon dioxide each year. Methane gas from cows and pigs and other animals on our large farms ends up in the atmosphere as well, trapping more of the sun's energy as heat.

There's nothing I believe in more strongly than getting young people interested in science and engineering, for a better tomorrow, for all humankind.

Evolution is the fundamental idea in all of life science, in all of biology. The key to our being here now is time, 4.54 billion (Earth) years of time. Nuclear fission wasn't discovered until long after Charles Darwin and Alfred Russell Wallace published their original books and papers, for example. Our ability to measure atomic masses wasn't developed until long after their deaths. These features of nature enabled us to reckon the age of the Earth and compare it with speciation rates here.

Talk about science with everyone you meet. Especially talk about climate change. It needs to become a part of our everyday conversation (the way it is everywhere else in the world).

Apparently there is redundancy in memory: You store the same memory in different parts of your brain for accessing at different speeds. That speed would depend on the frequency of use and the importance of the knowledge.

Anybody who grew up with the space program is a fan of science fiction.

Tax dollars intended for science education must not be used to teach creationism as any sort of real explanation of nature, because any observation or process of inference about our origin and the nature of the universe disproves creationism in every respect.
