Question for computer security experts

In his interview with John Oliver, Edward Snowden said something that many computer-savvy people are aware of and that is that modern computers can sweep through the entire set of possibilities of eight-character passwords in less than a second and that is how hackers break into systems. He suggested that rather than using complicated and hard to remember combinations of characters, we need to think in terms of long phrases that are easy for each user to remember but are unlikely to be found in any written form anywhere.

Explaining science and public policy using interpretive dance

John Bohannon, a microbiologist and science writer, and Black Label Movement (a Minneapolis dance company), argue that using interpretive dance would be much more effective than using PowerPoint in communicating things to the public. In this demonstration, they use dance to give the viewer a pretty good sense of how photons can be used to cool atoms down to almost absolute zero and transform it into a superfluid.

Amazing endurance feat

I came across a fascinating story about a tiny bird that puts human endurance records to shame. It was a about a small songbird called the blackpoll warbler that every autumn makes a non-stop flight from Vermont to Puerto Rico, a distance of 1between 1,400-1,700 miles that takes it three days to complete. This is a a pretty amazing feat for a bird that weighs just 12 grams.

The lead-violent crime connection and Kevin Drum

Kevin Drum has done some excellent writing about the case for a causal relationship between the amount of lead in our environment and violent crime, bringing to greater public awareness research done by Rick Nevin and others. I wrote about his article for Mother Jones on this topic last year and he now has a follow-up article looking at more research by Nevin, a leading proponent of the lead-violent crime linkage, that extends that argument to rural areas, saying that rural crime skyrocketed in the late 1800s because lead paint wasn’t readily available before 1880.

Who is the mysterious Egg Man? And how does he do it?

There is a very strange news story emerging from a Cleveland suburb near where I live. Since March 2014, someone has been throwing eggs at the front of a house occupied by an 85-year old man. This was not some isolated random prank by a child or a by a disgruntled trick-or-treater who decided to get their revenge long after Halloween. This has been a sustained attack of more than 100 eggs. These eggs were projectiles launched from a distance and hitting the house with remarkable accuracy.

The disadvantages of being a purely rational person

Scientists and atheists are among groups of people who value rational thinking, the former because being rational and logical in one’s thinking is essential if one is to be able to navigate one’s way through the complexities of trying to understand the workings of nature, the latter because taking a rational approach to life would make the absurdities of religious beliefs and the behaviors they generate more manifest. But of course, none of us can be purely rational beings in every aspect of our lives. The emotional centers of our brains respond to stimuli in ways that can overpower the centers that govern rational and logical thinking, as all of us can testify from personal experience when we have done soothing impulsive and stupid.
