RE: Defining time with atomic fountains

in #steemstem7 years ago (edited)

woaw, a brief history of time according to @lemouth AND an honourable mention omg i'm not worthy.

In other words, a leap second has to be inserted once every 300 million years!
so i guess i can rest easy in my lifetime on the part of measurement however (here i go again) from my obnoxious point of view this is still time as on observation through the change in systems (over time ... its paradoxical like that somewhat) where time is not an actual existing force that pushes or pulls or physically alters anything at all. It is defined (with great precision as i now understand) in order to be able to describe the changes in these systems. Where for instance i read about how a clock will behave differently the further away it gets from the core of the planet (the gravitational pull so to speak) and people write about that as if time itself slows down but, and as you describe here is that not simply the mechanics altering at atomic or sub-atomic level due to the change in gravitational pull ? it's fascinatings matter, well time actually i'll never get enough of this, thank you so much for taking the time (eh, it seems to be unavoidable, i see) to write this, but i think i will read the part on atomic physics 2 or 3 times more now

i see i'm not the only one with philosophical issues on the matter either here, but it's great to have debate isn't it

( im sure you must have read about it btw :: https://steemit.com/rudyardcatling/@rudyardcatling/link-to-bbc-stephen-hawking-ballot-opens-for-westminster-abbey-service , to be enterred between newton and darwin, that should make for great conversations during the witching hours there , shame i can't go )

thanks again for taking the time to explain it from your point of view in understandable language!!!!!

tsk, i wanted to give a 100% vote actually but i suppose that doesn't really matter much, fabulous work as always !

Thanks for the nice comment!

No it is not. Time is defined from something and that's it.

To answer the rest of the comment, time is a relative quantity and not an absolute one. For instance, as soon as gravitational effects matter, one needs to account for general relativity corrections. For the same reason we need to measure time very precisely in fact: this will allow us to test general relativity to a very high level of precision. See here for an experiment connected to this :).
