The Laser beam was invented on this day, 46 years ago.

Google is paying homage to this fact by changing its home-page.

It's very important in astronomy, it can be used to measure very long distances.

What an age.

Scientist 1: How far away is that? (points indiscriminately into the night sky)
Scientist 2: Ohhh I dunno...
Scientist 3: Wait, I know! We'll use a laser!
Scientist 1&2: *gasp* (while scientist 3 points laser pointer at sky)
Scientist 1: But I can't see the wee red dot?
Scientist 2: Yeah, THATS how far away it is.
Scientist 2&3 exchange a smug knowing glance.
Scientist 1: Morons...

Thanks, EvotingMachine, the printing one is perhaps the most well-known app for laser after eye surgery.

They use it to find hidden decay, eliminates the need for suturing in soft tissue operations, for root canal work and sculpting gums.

Personally - I owe my current (if tenous) employment to the Laser - We design and manufacture Lasers which etch and cut up silicon wafers.

www.xsil.com

Mad things alright - even tho I have to go every six months and get my eyes tested as Im exposed to lasers on a daily basis and there has been been this black dot following me around for the last 6 months Very Happy
