Others gave also valid answers, but here is one more: the experiments that are designed for testing a certain model or measure a certain property are, especially the beginning, as simple as possible (and as complicated as necessary) in order to eliminate as many error sources as possible. Also ther factors, such as duration, are also taken into account. In this case flyid dynamics was developed using water and air, because these were the relevant materials for our applications, are easily accessible, cheap etc. But then you end up with a physical theory that is *expected * to be valid for many different materials (based on the assumptions made), but has only been actually validated on only a handful of them. As the theory or model gets tested on more systems the boundaries of the feasibility of the experiment are stretched. Unless an experiment invalidates your theory, there is no reason to believe that the theory will not be valid for even more extreme cases, but you don't really *know* that. So here we are, after 100 years, waiting for that drop to fall. We are not exactly biting our nails in fear that laminar viscous flow theory will be invalidated (I would suppose the first few droplets took care of that) but why not gather more data while there is still pitch in the funnel?

Nope. I got something similar some time ago. It would not budge. I had to put it aside for a few hours for the bttery to die.

From the data in the report that the GP posted it does not seem that there is a negative effect of DRLs. They are either effective or irrelevant. Which makes sense: DRLs in sunlight do not blind you, they are just barely noticeable.

Hopefully, this year is about to end, soon.

The prices are a fractional multiple of a dollar, you see. So... Dollar Store!

Fortran's niche is scientific applications. Support for vectors, matrices, even imaginary numbers included in the standard library. Address-passing by default. Readily parallelizable using OpenMP and MPI with lots of constructs for using loops optimally. Sure you can use libraries to do all this in C/C++, too. But we are talking about convenience here.

Interesting that you mention chemical engineering. In some countries, like Germany, that are, often unwillingly, currently in the process of de-industrialization, Chemical Engineering does not look very promising. Production is in China and the engineering is moving to India. I would recommend to a yound chemical engineer to go into biotech: fermenter technology and the like. Foodstuffs and pharma are the two things that the "west" will keep producing and they both are fermenter-heavy. All other commodities are in Asia now. MSE is also promising, since new technologies are based on new materials, but I think that you can enter this are much more efficiently from Materials Science than Chemical Engineering.

Cool, I didn't know that, thanks!

We have only begun taking samples from "comets and asteroids". A sample or two are NOT representative of what's going on in the enormous universe.

Celibacy is what unites us.

Indeed. Would it also work if they were dressed as a chicken? Or a dog?

I was thinking about something more along the style of Flavor Flav.

All of them, of course.

There are a few used CRT monitors on eBay and AliExpress.

I often enjoy discourses where articulated, well-aimed, and thorough arguments are exchanged between the debating participants. But I also can't help but marvel at the spartan unambiguity of points like yours, especially when fired at point-blank range.
