Couplings are useful things, and they’re the next up in our series on mechanisms. Couplings like the one that failed on me have a few general uses. First and foremost, they do exactly what the ...

When repairing a section of pipe in an existing run, don’t try to cement (solvent-weld) all the new couplings. Most drain ...

Eight years later, the pair spin-orbit interaction (or spin-orbit coupling) was made explicit by Gregory Breit in 1928 and then found in Dirac's special relativistic quantum mechanics. This ...

Now a spin-orbit coupling that had previously been neglected is found to possibly be strong enough to give rise to an unconventional type of superconductivity in certain materials. The study by ...
