Dec 22, 2011 - It takes a lot more than just being gifted to teach. There are many 'gifted' people who can't explain all those amazing things that they do. Gifted people might not necessarily be able to get their point across.

Oct 24, 2011 - Yes, I probably should have had a "second"!! Interesting about the satellites accounting for the result; to be honest, I thought the most likely outcome would be that a flaw would be found somewhere in the experimental procedure...

joshmdmd Says:

Oct 23, 2011 - Thats not the correct way to use the word 'first'.. you needed to have a 'second' lodged somewhere in there. Neutrinos still don't travel faster than light. The satellites used to measure the speed of the neutrinos moved in the time period and this was not accounted for in the experiment. This total motion of the satellites accounts for the neutrinos speed to actually be less than the speed of light.
