☯When was the first vaccine developed?

First vaccines. Edward Jenner invented a method to protect against smallpox in 1796. The method involved taking material from a blister of someone infected with cowpox and inoculating it into another person's skin; this was called arm-to-arm inoculation.

☯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.

☸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.
