Solar Freaking Roadways! We at Washington’s Blog are big proponents of decentralized energy production and storage, because it is key to protecting against terrorism, fascism and destruction of our health, environment and economy. We noted in 2011 that a Dutch team figured out a way to make roads into solar generators. The concept is interesting: And a…Read More

Carl Sagan’s Bullshit Detection Kit

As per our earlier discussion, here is Carl Sagan. He argues having a finely honed bullshit detector isn’t merely a tool of science — rather, it contains invaluable tools of healthy skepticism that apply just as elegantly, and just as necessarily, to everyday life. By adopting the kit, we can all shield ourselves against clueless…Read More

MIT Model Recreates “A Virtual Universe”

Scientists at MIT have traced 13 billion years of galaxy evolution, from shortly after the Big Bang to the present day. Their simulation, named Illustris, captures both the massive scale of the Universe and the intriguing variety of galaxies — something previous modelers have struggled to do. It produces a Universe that looks remarkably similar to what we see through our telescopes, giving us greater confidence in our understanding of the Universe, from the laws of physics to our theories about galaxy formation.

xkcd: Randall Munroe asks “what if?”

Web cartoonist Randall Munroe answers simple what-if questions (“what if you hit a baseball moving at the speed of light?”) using math, physics, logic and deadpan humor.
