Absolutely. Those sirens need to be quieter. They are really annoying.

And larger conic tornadoes often furcate into a Devil's dance of tornadoes at the tip. Whenever the sirens go off I have a movie of those in my head. I am not sure that all the spawn co-rotate but my guess is yes. Perhaps I can find an example.

I would think that any afficionado of mathematics would be fascinated by the questions represented by Bertrand Russell and his Paradox. Does this not require some sure knowledge of groups and their foibles? (I am not a mathematics person)

I think you likely need to be more carefull in your definition of "absorbance". One cannot necessarilly conflate "scattering" with "absorbance". I do not know what your particular calculations provide.

I disagree. A much easier, cheaper, and more accessable model is the discharge of a capacitor. Volts is easier to measure than REM, and the invocation of something as exotic as radioactivity to this bedrock notion is counterproductive. Other examples abound.

I am pleased that the interaction was useful for you. It is the most one can expect! Good luck.

That is my first encounter with this term. I will endeavor to use it daily.

There are a host of atomic behaviors that do not comport with classical mechanics. This was seen to be a problem at the time, and most of them were illuminated by quantum mechanics, although for some the solution seemed as daunting as the problem.

If this really bothers you, may I suggest that you take up a more idiosyncratic pursuit. Perhaps painting or sculpture. Each work product has value because of its uniqueness: it will be redolent with individuality not easilly matched by artificial art (unless perhaps you somehow emulate Bob...

Different type of fallout from the Manhatten project. Lots of human mental capital in one location. "What do you mean the timing must be microseconds?" Just another day at the office for those folks.......

This is very counterintuitive ! Has no one noticed this previously ? What if the drop falls onto a liquid surface ? Gobsmacked, I am.

. Cerainly an excellent choice. Mike, Congrats. I reaelly hope you enjoy the task..

This reminds of the photographic work of the Lumiere brothers called autochrome I think. They made a custom shadowmask for each color. Diufficult but impressive work.

You need to pull equally on any "scale" to keep it in place while in use. and in general it is very useful to understand how a spring works. I don't think the two are equally necessary here. This post headed for the weeds faster than I would have deemed possible. I was just saying K. I...

Perhaps but who cares. For the purposes of this problem a scale is a black box with a hook and a calibrated readout of the static force on that hook. It could be filled with microprocessors and elves and it wouyld not be relevant to the question. Have humams here (and everywhere!) lost...
