Deep Space October 24, 2014 MAGIC Either Harrison Ford is in on the trick or David Blaine is God. Ninety seconds. You do not want to miss this. NOT MAGIC According to this — and a letter signed by 70 scientists — a lot of the games being sold as “fitness programs for your brain,” like Luminosity, are not effective. Digital snake oil. Which is good news for me, because long-time readers know I’m an investor in Posit Science, whose brain fitness program has been shown in peer-reviewed studies to work well. MORE MAGIC Thanks to Tom Stolze for the link to this brief look into the outer reaches of space. It is one of those things I can’t begin to comprehend. To say that Earth is a speck of dust in the greater scheme of things is all but infinitely to overstate our physical presence — and makes our tiny space ship, and the nanosecond of geological time it has hosted us, all the more miraculous. What a responsibility to our forebears and offspring not to muck it up. Please vote! And have a great weekend.
