I learnt today that the LHC and associated complex uses 220-300 MW of energy. Such a large amount of energy that the energy suppliers have various conditions about it being used, such as a 22 day winter shutdown and for most of its usage to be in spring and summer, when overall energy demand is lower.
I learned today that the word stereotype comes from a loom that makes copies of something thats allready woven, and that it makes a noise as the shuttle zooms by as it weaves, the noise it makes is ""kleesh kleesh kleesh" and that is where the word cliché" originates.
So interesting that the french and english word for the same thing comes from the same machine
It's not something that has any bearing on anyone else, but I recently (a few months or so ago) learned I'm left handed. I guess I had a grandmother that decided I shouldn't be so that's why I do everything with my right.
The documentary probably failed to state the evaporation time for the smallest black holes in the region of 10-40 seconds, not enough time for anything to happen in, that to create a black hole such as that in our currently accepted modal of physics requires far more energy than the LHC provides and finally, that particles with way more energy (cosmic rays) have been detected and are not forming black holes and are not doing anything else bad.
Getting back on topic, I should probably find something else I learnt today... Oh I learnt that P = NP is a conjecture that could be proven if you could make an efficient sudoku solver that works on arbitrarily sized sudoku grids.
Edit: (sources) You'll have to take my word on the second one. I saw it on a lecture given Avi Widgerson on P = NP? (which is on Youtube and is excellent). He doesn't cite a source, he just says that sudoku puzzles are NP-Complete.
As for the first, you can just read about the physics yourself if you don't believe me.
