comment When does a pot not spill?
Sharp edges could be part of the answer. I also see different shapes and angles. Moreover it seemed to me an elliptic container drips less from the flatter side. What about the material? And why the fancy shapes of teapots openings?

If you have questions about details just ask. After you have poured the liquid there are often drops dripping. Some cans do that. Some don't.

OK, thanks. I see :)

@Jerry: No, I rather do theory than experiments and I'm glad there are people who do experiments for us. I'm just wondering why that ivory tower of research. If you obviously don't know an answer - get over it and don't get mad. If you can't take a critical view, just don't answer.

But does any of these discoveries rely on more than basic understanding? (see comment to Arnolds answer) Do you need calculations which a more "quantum-mechanical" than quasi-classic simple theories?

I mean QM calculations in particular. Do you need DFT and it's cousins to develop a transistor? Of course, some basic understanding is important, but in the end most devices are found by experimental trial and error?! Theory often lags behind and hardly ever reaches full agreement with experiments? So what's the point of theory from the practical point of view if it's cheaper to do an experiment rather than occupy a server-cluster for a year and still be wrong?

comment Evidence that “space exists rather than just particles”
That tone sounds like religion not like science. Your personal opinion is surely not enough for an answer. And stating one example where you need space isn't an answer either as it's rather about pointing out why there is no way to avoid that. I asked a question looking for concrete mathematics disproving the particle picture. As mentioned discrete space-time is some intermediate case.

Hmm, it's not really the same. In a way it means "being discrete in terms of particles", but I doubt discrete space-time means only particles are space points?!
