Assume you’re an astronaut flying to Mars sometime in the near future. When you finally arrive (after a trip of anywhere from 150 to 300 days), where will you stay? Someone is working on that. Suppose a robot with a 3D printer went first, gathered local materials, and printed the Martian base’s infrastructure before any
Why trust Science? This has become a pertinent question, especially in the current political climate. Science has a role in so many aspects of our lives, from our jobs to our health to our environment. Yet, despite being able to time solar eclipses down to the second, there seems to be more distrust of what
Talk about weird science –– can plants learn? Or at the very least, can they remember? Try a simple experiment. Place a plant in an enclosed box with two holes in the top to admit light. Open one hole for a specific period of time, long enough for the plant to grow toward it (plants
It came as a shock to me to hear that all rainbows are not the usual kaleidoscope of colors. There are different kinds of rainbows, including some that are almost all red. They are rare, but they can be found. Basically, red rainbows happen when the sun is on the horizon. When the sun
On September 20, 1848, the American Association for the Advancement of Science was founded in Philadelphia. (http://www.aaas.org/) Its purpose was to “procure for the labors of scientific men increased facilities and a wider usefulness.” This was actually a new concept, the term “scientist” having been used in England for the first time in 1833. Of course,
Here’s an interesting entry from The Writer’s Almanac of July 20, 2015 — “It was on this day 140 years ago, in 1875, that the largest recorded swarm of locusts in American history descended upon the Great Plains. It was a swarm about 1,800 miles long, 110 miles wide, from Canada down to Texas. North
Yesterday I received an email from The Planetary Society about Asteroid Day. Beginning at the beginning, The Planetary Society is an organization for people interested in anything involving space — “We create. We educate. We advocate.” One of their latest activities has been to support the LightSail experiment — using the solar wind for
Earlier I had written about the dangerous chemical dihydrogen monoxide, which is actually a hoax to embarrass people about their ignorance of science — dihydrogen monoxide is the chemical name for water. (Do you remember from high school chemistry that di is two and mono is one? Thus two hydrogen atoms and one oxygen atom
Time magazine is reporting that according to a recent Microsoft study, our average attention spans are now down to about eight seconds. This actually puts us as less attentive than goldfish, whose attention spans average about nine seconds. Time reports that Canadian researchers surveyed 2,000 participants and studied the brain activity of 112 others using
I know there are some people who simply don’t trust science. And there are times when mistrust is warranted. Remember cold fusion? Of course, there have also been outlandish-sounding theories that have turned out to be correct, like continental drift. That’s why there is the scientific method and research needs to be replicated multiple times
