Battery life decreases during in the cold.
Some studies suggest 20-40% reduction, although in modern batteries this is only temporary. This is due the the atoms (or ions in the case of batteries) randomly moving at a slower pace. We must thus impart them with more energy to make them move. A representation is trying to get something over a hill. We need to impart force to get them is, and after the crest of the hill they can “travel” the rest themselves. Thus the crest represents a threshold which must …
Some very exciting news via NewScientist that the first particle of dark matter has been discovered. We’ll know on the 18th Dec - when a paper will be published in Nature, whether or not it’s the one speculated will have to wait………..
A couple of favourites from college and friends working in Science (apologies in advance!)
2 Hydrogen atoms walk into a bar. 1 stops and says:
“Oh no, I’ve lost my electron!”
“Are you sure?”
“Yes, I’m positive.”
A bacterium walks into a bar, and heads towards the barman.
Barman: “Oi, no bacteria allowed in here.”
Bacterium: “It’s OK, I’m Staph!”
Interesting to see the LHC is back up and running in Switzerland. There was furore last time it was started, unfortunately it was put out of use for a number of months due to an accident. Having just smashed to particles together for the first time yesterday, there seems to be less opinion around the place. We’ll put it down tot he economy and the public sector strike!
