I created Starry Night with Ted Leckie years ago. Now we do OS X document management applications. Try Fresh.

comment If two ultra-relativistic billiard balls just miss, will they still form a black hole?
Re:'relax to spherically symmetric Schwarzschild' will actually look like quite the explosion. The black hole will last all of 1e-10 seconds or so as it evaporates. That's 1kg of energy released in a short time. Don't stand too close!

comment What are the practical applications of quantum foundations?
I like the Mayan story. Its easier to use people who lived a long time ago as 'dummies' than the smart scientists of today. New, 'better' theories will always have a hard time replicating known results, as the amount of work on the accepted theories is large. If the staggering amount of work on accepted theories today is taken into account, its obvious we will need a bombshell experimental result to get anywhere. That's why physics is stuck.

comment Are there any QM effects where charged particles are not intimately involved?
Thanks. (I did mean electric charge). I cannot think/find any examples either. What I am getting at is that perhaps QM is more entangled with electric charge than the theory lets on.

That's a nice shape. You can see the air changing the parabola in the correct manner.

revised Do photons interact only with single partles or can a single photon be absorbed by 2 or more particles simultaneously?
added sentence to relate to the title of the question.

The Stern-Gerlach experiment is a case in point - its all about magnetism and charged particles. The fact that you measure a QM effect on a charged particle is not a surprise. The weak and strong interactions also always involve charged particles.

comment Distance travelled in spaceship Newton vs Einstein
I was kind of pointing out how you don't have to enlist other observers at all. Most SR examples use two observers, the aged one one left behind vs the traveller. But you actually get farther with SR for the same proper time and fuel usage as you would with Newtonian mechanics. Put another way - the limiting speed 'gamma' factor is more than compensated for by the time dilation.
