Does Einstein's famous equation really matter to us in our day-to-day life?

Answer 1

About as much as who is president matters. That is to say, not much at all, directly, but quite a bit indirectly. Without E=MC^2 there could be no nuclear bombs. And depending on who is president, we may or may not go to war and possibly use those nuclear bombs. (That is just an example that is easy to understand and not a political statement.)

Answer 2

The mathematical expression of the fundamental relationship between matter and energy is pretty dog-goned important in some very practical ways.

It's kind of neat, isn't it, to think that everything you are -- your very body and everything in your environment -- can be thought of in terms of unexpended energy.

It's also kind of neat to think that every bit of energy -- every sunbeam, every tiny bit of heat from your fireplace -- can be thought of as being not essentially different, really, than the sleepy dog who's taking a nap in a sunny spot, or in front of the fireplace. Rather, the sunbeam and the heat from the fire (on one hand) are just different expressions of the same thing that takes shape in the form of the sleepy dog. Energy equals mass...

The energy from the sun gives our planet life. It warms the planet. It triggers the process of photosynthesis whereby we get oxygen. It stirs the atmosphere, giving us refreshing rain. In an essential way, you and I are nothing more -- and nothing less -- than sunlight that's being expressed in a slightly different way.

That is the true significance of Einstein's famous equation.

Answer 3

The sun (as for any star) produces its light through a fusion reaction where light nuclei fuse to create heavier nuclei. For example (hydrogen fusing to form helium). In that process some mass is converted into energy by an amount predicted by E=mc^2. Without that nuclear reaction the sun would produce no light and we wouldn't exist. I would say that matters a lot.

Answer 4

ya a lot
life is a physics everythings around u are realted with physics
and physics are based on Einstein's famous equation

Answer 5

Yes, it does in many ways not just in nuclear activities but observing it scientist can predict the supernovae and also the destructive strength of a comet, take if a comet weighs 1 gram and it travels the speed of light then it's total energy will be 3x10^5
square, how cool was that?

Answer 6

Of course..

in all nuclear reactors is applied

And in the concorde trips to measure the time dilatation

Answer 7

yes it helps us to calculate the energy relesed in a nuclear reaction

Answer 8

Everything is relative!
