GOD I want people to understand this.

This guy was more than a great phycicist he was a great human being - if it were possible to choose ones father I would not hesitate to choose this man.

yeah, string theory hasn't been tested, so they would have no reason to do that.

oh right, modern physics usually deals with microscopic phenomena which classical physics can't deal with. but when you develop a modern (micro) model, it has to produce to classical result if you expand its parameters. that's why i didn't say the GOAL of modern physics was to give the classical result, but that the check mark is given to modern models if they can produce the classical answer if it's expanded.

I believe you mean aspires.. conspires usually implies malicious intent..

the goal of modern physics isn't get it to match previous classical results: modern physics produces the "right" answers. read the introduction to feynman's lectures on physics, it should be on google somewhere

[Kevin Erazo]

right, that's why i said we gained a deeper understanding of the phenomena. And btw, the test of "modern" physics is that it conspires to produce the "classical" results. If any new physics contradicts previous results, it's discarded.

[totaljking12]

calculations remained unaffected but our understanding of what's really happening was totally changed.. in that sense classical physics was totally effected and it is why we separate the two 'physics' into classical and modern

[Kevin Erazo]

actually most of classical physics remained unaffected by relativity which is only relevant at high speeds. Einstein contribution was to create a more fundamental framework to work on, but as he worked he had to make sure his equations conformed to the established classical physics. So he didn't overthrow the consensus, rather he went deeper and allowed us to find out more.

...And as soon as that consensus is reached, a guy like Einstein comes along and proves that "consensus on truth" wrong.
