9-year-old Carissa Yip is probably better at chess than you. She is certainly better than me and already better than 93 percent of the 51,000 plus players registered with the U.S. Chess Federation.…

"Those among us who are anthropologically inclined tend to view a can or bottle of soda as an instantly recognizable symbol of everything that is wrong with Western civilization as we know it" is the…

I've long said that energy is the biggest issue we face in the 21st century - with energy, I can solve the problems of food and water and that helps solve poverty too. I can even turn lead into gold.…

It would be great to study Mars "on location". You could do as much in a day or two, as our rovers could do in years. But there's a conundrum to face. Humans are host to hundreds of trillions of…

After reading another article by Alex Berezow ["The Arrogance of a Well-Fed Society"] insisting that there is absolutely no problem with human population growth, I couldn't help but be struck by the…

If there are fewer than 50% females in physics, that is a call to action, argues virtually ... everyone in academia. We need greater outreach for girls, we need to change classes to appeal to them,…

Voyager 1, launched in 1977, has now traveled further from Earth than any previous launched object - 11 billion miles and counting. It is on the edge of our solar system and about to enter deep…

For the first time, astronomers have measured the true colour of a planet in orbit around another star, and it is cobalt blue. This blue however, is probably the colour of a continuous rain of liquid…

In 1953, the lightbulb went on for Watson and Crick, who first published the famous double helix 3-D structure of DNA. Structural biology soon became a hot field. Using high intensity X-ray beams,…

This is a draft article I wrote for wikipedia. about the legal issues and requirements for public debate for return of a sample to a Mars Sample Return Receiving Facility. It is background…

About once a week I use some specialized chemistry and physics to blow up cars for movies.  Here's a little video revealing how that works, that I shot while creating a scene for Rooster Teeth..…
