Hope you get this on time, I made a trip to Madrid, Spain and had my bag stolen from me with my passport, cash and credit cards in it. Unfortunately for me, I've made contact with my bank but they are not providing a fast solution. I need you to lend me some money to sort my self out of this predicament, I will pay back as soon as I return.
Western Union transfer is the best option to send money to me. Let me know if you need my details(Full names/location) to make the transfer. You can reach me via email or the hotel's desk phone +34962463149.
I await your response....

I know nothing about Mr Higgs or his whereabouts but I do recognise a
significance test when I see one.
Or do I?
The BBC explains recent developments at
http://www.bbc.co.uk/news/science-environment-16116230
which includes
- *· "Particle physics has an accepted definition for a
"discovery": a five-sigma level of certainty*
- *· The number of standard deviations, or sigmas, is a measure
of how unlikely it is that an experimental result is simply down to chance
rather than a real effect*
- *· Similarly, tossing a coin and getting a number of heads in
a row may just be chance, rather than a sign of a "loaded" coin*
- *· The "three sigma" level represents about the same
likelihood of tossing more than eight heads in a row*
- *· Five sigma, on the other hand, would correspond to tossing
more than 20 in a row*
- *· Unlikely results can occur if several experiments are being
carried out at once - equivalent to several people flipping coins at the
same time*
- *· With independent confirmation by other experiments,
five-sigma findings become accepted discoveries"*
*
*
Can anyone tell me whether this is really a fair summary of how physicists
work?
