How did Google get its name?
After almost calling google ‘backrub’, Larry Page's (co-founder of google) friend, Sean, suggested googolplex, the number googol to the power of ten (one with 100 zeros).
How ever Larry settled with the shorter term, googol. Sean, not realising googol was spelt with an ‘ol’ and not ‘le’ searched to see if the domain “google.com” was available.
Larry liked the name google and stuck with the new made up word which we all know of today.

Why do ceiling fans get dusty?
The latter is the case for ceiling fans.
As the blades rotate, they experience frictional forces as they `rub' against the air; this knocks electrons around, causing the blades to build up a net charge.
The charged dust particles then stick to the charged areas of the blades.

Why is 1921 an important year for mountain climbers?
Because it was in that year that Dalai Lama gave permission for Everest to be climbed for the first time.
This first expedition was mainly to discover if a route to summit could be found from the Tibetan side.
However, though many dreamed of standing on the rooftop of the world, they were all doomed to failure.
In 1922, seven sherpas died in an attempt by the British expedition led by George Mallory to reach the summit. In 1924, a third expedition managed to reach 8572 meter, but two members of the team, Mallory and Irvine, disappeared into the mist and were never seen again!
Mount Everest continued to lure climbers after climbers, but it was only in 1953 that it was finally conquered.
