In the lab frame youngs slits are easy to understand once you associate a de Brogle wavelength to the particle. I wonder if anyone has a manner to visualise/understand youngs slit interference in the frame of the particle i.e. one where its wavelength is infinte.

There is a probable upper limit in temperature to the usefullness of a superconductor. All the known high Tc's are type II, that is in the presence of a magnetic field, external or produced by the passage of a current, the field is quantized into vortex lines. These lines feel the Lorentz...

mach and the flat potential If by "mass" you mean "proper mass" then that'd remain invariant. If you mean "relativistic mass" then it'd change as determined by an external observer. This was interpreted by Einstein to be a confirmation of Mach's Principle. Pete This statement interests...

Inside a shell of matter I would experience a flat gravitational potential and hence no gravitational force. Is there any experiment I can do, short of leaving the shell, that could allow me to determine the existence of the potential? For example would my extra potential energy show up...

Anyone tried to imagine a world with negative mass? A mixed world of normal mass and negative mass does not seem so bad in the sense that a negative mass moon would surprisingly still orbit the earth! Might be problems in making atoms though...

Inertia has always bothered me in the sense of the actual mechanism behind this resistance to acceleration-why? I believe Mach had some idea that the gravitational attraction of the rest of the universe was behind it but did he manage to prove anything? Certianly Einsteins equivalence principle...
