Science is conjointly fun when it goes ‘bang’

How many people know, Marasinghe said, that understanding Einstein's theory of relativity is what acknowledges the global positioning system to work?

The theory explains that for an object that's traveling very fast — say, a satellite traveling at 18,000 mph relative to the Earth's surface — span flows slower. Because GPS receivers triangulate their location along Earth by timing the signals from the satellites, it's critical that they adjust for tiny changes in the flow of period.

So, e=mc2 eventually led to a helpful not much gadget that says “turn left this day."

“By the time students get to high school level, in a ritual, they are programmed to think science should be hard including not something they want to follow," Marasinghe said.

They're easier to reach when they're younger, he said.
