  1. tzx9633 liked Chestermiller's post in the thread Flow in anistropic soil.

    kx/kz = 2, not 1/2. And the original horizontal distance scale before change of variables was 7.6 m. So the new horizontal distance...

  2. DrClaude replied to the thread 2 degree of freedom system modelisation.

    Doesn't the picture show 3 degrees of freedom? From the point of view of particle 1, does it matter if it is being pulled by the spring...

  3. zonde replied to the thread B Entanglement, what is it?.

    Before attempting to solve the problem yourself you can try to look how others tried to do that. There are some references at the end of...

  5. CalcNerd liked kimbyd's post in the thread B Does gravitational wave change the speed of light?.

    Because you're using different notions of "speed" in each case. The speed of light is a local speed. It's how fast the photon is...

  6. CalcNerd liked berkeman's post in the thread Physics Career advice to become a Fusion Engineer.

    Welcome to the PF. :smile: I'm not sure I can help much, but when you read the biographies of the scientists working on ITER and the...

  7. CalcNerd liked ZapperZ's post in the thread Physics Career advice to become a Fusion Engineer.

    There is no such thing as "fusion engineering" exactly. There is, however, nuclear engineering, which does encompass fusion and fission...

  8. CalcNerd liked Vanadium 50's post in the thread Physics Career advice to become a Fusion Engineer.

    Canadian citizens are not eligible to join ITER. ITER's public schedule has them running d-t in 2035. There is no way a successor will...

    There are no momentum detectors in laboratories. Instead what experimentalists do is use some sort of momentum splitter or filter and...

    But isn't Everett's theory more deterministic? ah, so that really implies that there is a link. A problem indeed

    Sorry, no such device exists, batteries don't create energy, they store it.

    Why does NO3^(2-) get reduced instead of H+ in Cu+HNO3

    doesn't make sense, h+ just has a really nice positive charge which is begging electrons but electrons go to the NO3(^2-) instead? why?
