Tidbits from New Scientist

From the Feedback column:

Why does NASA show the movie Armageddon as part of its management training programmes? We’re talking about the thriller in which Bruce Willis saves the Earth by nuking an asteroid the size of Texas into dust just moments before it wipes out the home planet. If your first thought was that they’re training NASA managers to put the proper PR spin on any doomsday asteroid, the door to the paranoid ward is on your right.

In reality, the screenings are just a game for NASA’s space geeks: who can find the highest number of impossible things in the movie? The record, Feedback is told, stands at 168.


Did you ever wonder what gives the tangy taste to salt-and-vinegar flavoured potato chips? It’s sodium acetate, Feedback learns in a press release from the American Chemical Society, which cheerily informs us that the same compound “is the key to a new waterproof coating for protecting concrete from water damage”.

It seems that sodium acetate seeps into the pores in concrete, where it hardens and forms crystals when exposed to water, blocking the entry of additional water. By preventing further water absorption, the new coating “can be expected to increase the service life of the concrete”, the release goes on, leaving us wondering about the service life of our stomachs.
