A similar thought (about 1^x) had occurred to me, but I wasn't aware that it was common practice (in some field, at least).

Do you have a reference?

I recently implemented something somewhat similar, but from the perspective of set membership.

I therefore needed to include a complement operation, so that I could do full Boolean analysis of interval membership.

Your intervals are all closed sets, consequently the complements are open intervals. I chose not to distinguish between open and closed intervals, since for my practical purposes whether the end points are members of the set is unimportant.

Of course, with inexact arithmetic, the question of whether the set is open of closed probably not well-defined.

I can't make an intelligent contribution, but I found it an interesting read, and thank you for posting it.

X makes its money selling advertising. France is the obvious place to have an office selling advertising to a large European French-speaking audience.

I would guess that is intended for a daily cycle, perhaps using air source heat pumps at times of day when the air temperatures are higher and electricity prices are lower, then using it as required.

As it works on phase change (e.g. think of melting ice) heat is added (or removed) without changing the temperature of the store (which, I guess, might be hotter or colder than where the heat is extracted or used).

Presumably he is regarded as more sensible than some other candidates that might have appealed to the President.

I was hoping that someone would be able to point me to some practical technical advance enabled by discoveries or measurements at CERN (or similar establishments).

It seems plausible to me that better understanding of the properties the subatomic particles might enable some previously unexploited technology (e.g. in quantum computing or sensing).

As someone who supports pure science research, I would be interested to understand if any of the discoveries of CERN (and related projects) in the last 50 years (say) have proved to have practical application.

(Specifically, "discoveries", not technology developed in support of the research)

I sometimes run my MATLAB code under Octave (generally needs some minor tweaks to catch up with a few new features) and while I don't hit bugs, I find it is much slower.

I think the MATLAB JIT compiler is probably difficult to match.

Is that "No, I never open sourced anything"? Or, "No, I have open sourced things, but never regretted it"?

An interesting game, if you can come up with enough good questions. (At least it isn't telling me which digits are right, but in the wrong place).

With a target of 20% accuracy, it won't make much difference, but I think that symmetrical error bounds are appropriate in this case - the factor by which the answer is wrong. so 2 times too big, is as good as 2 times too small.
