The Malcolm Gladwell problem

Malcolm Gladwell has made a good career out of taking a few research findings, buttressing them with a few stories from here and there, and creating sweeping, plausible, and appealingly counter-intuitive theories about human behavior, while ignoring anything that disagrees with his thesis. As someone once said, the facts agree with Gladwell’s theories except when they don’t but you’ll have to find those on your own. [Read more…]

The NFL is like the tobacco industry

Last evening I watched the PBS Frontline program League of Denial that I wrote about yesterday. (You can watch the program here.) It showed how playing football can cause traumatic brain injury that can occur from the normal give and take of playing football, even without any concussions. Autopsies of players as young as 18 have shown them having a particular form of brain damage called chronic trauma encephalopathy (CTE). [Read more…]

Let the physics Nobel arguments begin!

As expected, this year’s Nobel prize in physics, announced today, was awarded for the discovery of the Higgs boson. The prize was awarded to two people, Francois Englert and Peter Higgs. As I said in one of my series of posts on the Higgs boson, the award of the prize was bound to raise hackles because five theorists had some claim to the discovery (there were six but Robert Brout died in 2011), as well the experimental groups that found the particle last year, not to mention CERN, the laboratory where the experiment was done.

Scientists call for boycott of NASA conference

It turns out that in March this year, congressman Frank Wolf, chair of the House of Representatives Appropriations Committee initiated a bill that incredibly was allowed to become a law that prohibited Chinese nationals, even those who are already in the US and working at US universities and other institutions, from even setting foot in a NASA building. The reason given was the risk of espionage. [Read more…]

The importance of large animals

We know how the extinction of the dinosaurs completely changed the balance in nature and led to the emergence of large mammals.

But they are not the only large animals to play such a significant role. In this clip from Ted Radio Hour, George explains how returning wolves to Yellowstone National Park in 1995 after a 70-year absence affected so many aspects of the ecology there, transforming it. [Read more…]

New solar cell efficiency record

Although I am a strong supporter of solar energy, I had not been following developments in that area so I was pleasantly surprised at this news report that a new solar cell had broken a new efficiency record with 44.7%. What this means is that 44.7% of the light from the sun, from ultraviolet through to the infrared part of the spectrum, is converted into electrical energy. [Read more…]
