comment Solar stills with Wine
@namehere that's a good question I would hope an actual chemist or chemical engineer would calculate for me, but I'll think about it...

comment Scientists observe the laws of the physics but, Where do they come from?
For the record, I don't think this is a bad question per se, nor that scientists shouldn't give it some thought now and again. It's just that, for better or for worse, physics proper decoupled from metaphysics 250 years ago, and this question certainly belongs in the latter category. Have a look at Philosophy.

comment Aftermath of Plasma Arc
Are you thinking of chemical changes (i.e. formation of molecules, as opposed to nuclear transformations), for instance as occurred in the Miller–Urey experiment?

comment Perceiving travel speeds from different view points
@gj255 I worded that confusingly. I mean that even scenery passing by at a full 200 km/h doesn't look to be moving so fast.

comment Best Research Documentation Habit for Computational Physics Research
I'm weakly in favor of this being on-topic as far as the coding/documentation angle is concerned (we allow computational stuff already), especially if the focus is on physics-specific techniques. If this is off-topic, IMO it should be because it solicits opinions. Perhaps we can take this to meta?

comment Why do we use time-dependent regions in this derivation?
This might not be needed to answer the question, but what are $\mathbf{b}$ and $\mathbf{S}$ here?
