The difference between an implicit and NPT simulation is way to high. What could be the explanation?

We perform MD simulations with Amber on a protein dimer in different circumstances. In implicit solvent on 350 K the dimer dissociates after 2 ns, while in water box, NPT run it is still stable...

Physics: Why do we describe light by referring to its wavelength, but microwaves and radar pulses by referring to their frequency?

In physics, the description of the properties of light generally refers to its wavelength (nm), while in the range of microwaves and radio waves we refer to the frequency of a signal (e.g. kHz or...
