Via Machines Like Us I came across this demonstration by Audi of a car that will, by itself and without a driver, find a parking space in a parking garage and park itself and then return to you at the entrance when you call it. [Read more…]
I like to periodically clean up the spaces around me because I hate clutter but we all know people who seem to be minor or major hoarders, reluctant to give or throw away things that they have not used in years, are unlikely to ever use, or are even totally useless to them. They seem to not even be bothered by being surrounded by piles of stuff or to even notice it. [Read more…]
One sometimes hears that humans use only about 10% of our brains. Some have suggested that this means that if only we could learn how to harness our brains fully, we could be geniuses. Others have used it to argue, somewhat desperately, that this limited utilization is the reason for god’s ineffability, because in the unused portions lies the ability to understand how god works and what his plan for us is.

When I attended a K-12 school in Sri Lanka, we had eight class periods that started at 8:30 am and ended at 3:05 pm. Within the day, there was a 15-minute recess from 10:30-10:45am and one hour for lunch from 12:05-1:05pm.

Most people know that the winter solstice December 21 corresponds to the shortest day of the year in the northern hemisphere. But some go further and think that this date also corresponds to the time of latest sunrise and earliest sunset. That is not true. The earliest sunset occurs around December 8 and the latest sunrise around January 4. [Read more…]
As I reported earlier, a whole lot of people including me, fell ill over the holiday break with what was very likely a norovirus infection. Carl Zimmer has just written a fascinating article on the remarkable family of noroviruses, based on an paper published in a recent issue of The Journal of Infectious Diseases by Aron Hall of the Centers for Disease Control. Zimmer writes: [Read more…]
Well I am back blogging, refreshed after nice holiday break spent at home. We had both daughters and their significant others with us and since this happens so rarely now that they are grown and have their own lives and careers, I took advantage of the opportunity to just hang out with them.

I heard this report on NPR four days ago about a project to take photos of Mount Everest that exactly match those taken over the last century to see what changes have occurred, especially the extent to which the glaciers have receded. [Read more…]
