Low Frequency Radio Transmission for long distance.

IME they're used only where the impedance level is the same between measurements, e.g. with wave propagation and so on. The BSTJ article I posted says that by international agreement the neper was defined as a power ratio of e**2.

At least in the high energy physics they were lucky. Originally they used fermi (1e-13m) abbreviated as fm. The correct SI unit is femtometer which also is fm. :-)

The US doesn't have that problem: bil == 10^9 and tril == 10^12.

Or suffice it to say, unimaginably large, and a thousand times larger still.

But femtometer is a different size, 1e-15 meter. How was that a good thing?

Teamsters on the $1 bill, AFSCME on the $100. What bill do we put Soros on?

For 2016, it looks like Donald

That's horrible of Donald to finance his own campaign, obviously hoping to buy influence with himself.

Well, I was thinking of campaign contributors, not PACs and lobbying. It would be awkward to put a face on the on the currency representing the AMA etc. Europe had the same problem deciding what to put on their new euro notes and selected mythical bridges as something nobody would be likely to protest. Some details will need to be worked out on selecting photos.

Well, my view from above is that Trump could not convince either party or any major contributors to take him seriously. His candidacy was generally taken as a joke until he managed to attract the attention of people who probably have never bothered to vote, or traditionally vote Democrat. That got the attention of the Republicans, who were stuck with a motley collection of candidates, none of which had any chance of actually winning.

That's important because the election is really about convincing the self-disenfranchised, illiterate, uneducated, clueless, uniformed, and lazy members of the GUM (great unwashed masses) to drag themselves to the polls and vote. Past history has shown that various political, social, ethnic, and employment groups tend to vote for the same parties every election. My guess(tm) is that about 90% of those that actually vote are quite predictable and split rather evenly between the major parties. So, why should the parties waste any time and money on this 90% when the election is determined[1] by the unpredictable remaining 10%? What Trump has done it get the attention of a fairly large portion of this 10%, which makes him the only one among the prospective Republican candidates with a chance of winning.

[1] The election is not determined by the popular vote, but rather by the vote of the electoral college. Untangling the mess requires some knowledge of which states require their delegates to all vote for one candidate, split the vote according to the popular vote, run amuck with delegates voting as they see fit, or various combinations and permutations. In some cases, the money does not go to convincing the voters, but rather to convince specific delegates who often have a personal agenda.

Hmmm... Looks like the campaign contributions are now rolling in for Trump:

Also, he didn't donate the money to his own campaign. It's a "loan".

I'm pretty sure the fermi has always been 1E-15 m, i.e. roughly the diameter of a proton. In one of their occasonal sensible moves, the BIPM preserved the abbreviation by choosing "femto" as the prefix for

1e-15. (It's from the Danish word for "fifteen".

He doesn't. He "loans" himself the money and gets it back. His idea of a "charitable contribution" for tax deduction purposes is giving someone a pass for a round of golf at one of his golf courses. Aside from that he has the record for being one of the least contributing rich men in America... EVER.

It does not get any more lame than Donald Trump.

I think it was originally defined as 1E-13 _centimetres_, which may be the source of the confusion. Physics used to be mostly done in cgs units. (I st ill use cgs Gaussian units for EM hand calculations--it's easy to convert t o SI afterwards.)

What charitable causes do you donate to?

My little company donates to a bunch of causes, about 10% of our annual profit.

When was the last time a presidential elector voted for a candidate other than the one they were selected to vote for? You seem to be confusing the presidential election with the party selection of candidates.

48 states are winner take all. Two are by congressional district, with the two representing Senators being by state-wide popular vote.

It's not common, since they're chosen from politicians of the winning political party. It does happen, though. Mostly as some foolish sort of protest vote (temper tantrum).

the only SI currency units I'm aware of in common use are

"cents" = $centi "megabucks" = $M with "kilobucks" in uncommon usage.
