Quantum Theory

Normally I am quite sceptical concerning hybrid and new technologies for communication and prefer the classical set-up with people in front of me I can interact with. But this was surely a very good example to the contrary. I would have never thought that it is in fact possible, even fun to have a good colloquium via internet. (It’s possible to have one, but whether it is good is another question. This one I found was good.) I have done that once previously and found it very tedious, because there was always the odd glitch. Now it worked perfectly well.
