Pace Maker1959
John Hopps a Canadian inventor created
the first cardiac Pacemaker. He found out
a heart slows and stops due to cooling ,
and it could be started by mechanical or
electrical means.A Pacemaker works by electronically
monitor your heartbeats and when your
heart goes out of beat it sends a small
electrical shock to throw it back in
normal beats.

Micochip1959
Also Known as a Integrated Circuit, It was a thin substrate of semiconductor material used for holding information.
To create it two competing companies owned by Jack Kilby and Robert Novce had to work together and made a company worth over 1 TRILLION dollars and more every day.

A few things the laser was used for back then was, Laser lighting - Displays for advertising and entertainment, And Laser skin care - Hair removal, acne treatment and other dermatological uses.
