We will look at a very easy experiment that provides lots of information ... Again, it is not always that simple. We need to understand the different meanings of “strength” or engineering stress. Let ...

How it's very beautiful ... That's certainly physics, but it's a kind of physics that is not yet testable. It does not make predictions that have anything to do with experiments that can be ...

At very small scales, we know the universe is made ... Goudsmit and Uhlenbeck's spinning electron proposal caused an uproar in the physics establishment. At this time, physics was shaped by ...

None of this is magic, of course. Rather, as optics aficionado [Les Wright] explains, non-linear optics is all about physics. Big physics, too, like the kind that made the National Ignition ...
