Bangalore: Some scientists are born to experiment on new things with an aim to invent, while a few become surprising victims of accidental experiments landing on life changing discoveries that gain them accolades. Here are top five popular accidents in the history of man-kind that led to the discovery of notable scientific inventories.

#5 Pace-Maker

Accident causer: Wilson Greatbatch

An Assistant professor’s device tampering lead to one of the greatest technological invention in surgical field- pace-maker for the human heart. Wilson Greatbatch was working on a device that could record fast heartbeats. While designing the circuit for his experiment, Wilson reached for the tool box and instead of pulling out a 10,000-ohm resistor, he accidently picked out the 1-megaohm variety. This caused the circuit to act differently. Instead of recording fast heartbeats, the circuit pulsed for exactly 1.8 milliseconds and paused for 1 second; a dead imitation of a human pulse range. Greatbatch immediately started working on the new circuit and developed the first ever pace-maker that proved to save millions of lives.
