I found this video by Minute Physics on YouTube the other day. It gives a nice and clear explanation of the Higgs boson. So if you are still confused about what all the fuss was about on Wednesday, I recommend that you watch this short video:
To the bafflement of scientists, a cylinder of metal sitting in a closely-guarded strongbox that is the global benchmark for the kilogram is changing mass.
The enigma doesn’t affect anyone who wants to buy 500-milligramme tablets of aspirin, half a kilo of carrots or a 50,000-tonne cruise ship.
But it poses a hefty theoretical challenge to physicists, and complicates the work of labs which need ultra-precise, always-standard measurement.
Since 1889, the kilogram has been internationally defined in accordance with a piece of metal kept at the International Bureau of Weights and Measures(known by its French acronym of BIPM), in the Paris suburb of Sevres. Continue Reading
