Defending Al Franken?

There are two accusations against the comedian/senator: first that he forcibly kissed the woman against her will, and second, that he groped her while she was sleeping and was photographed doing it. The trouble with the first accusation is that his accuser admits that she agreed to be in a skit in which he tried to kiss her, and further, that she agreed, however reluctantly, to rehearse the kiss. This is a gigantic hole in her story of being kissed against her will. Her problem was that she just didn't like the kiss. When you sign up for an acting gig, rehearsal is a an expected consequence, and the time to protest is before, not after. She also reports that she angrily pushed him away. That's not an appropriate way to react to a scene not going exactly the way you expected, and Franken was understandably offended, maybe as much as she was.

The second charge, groping, or simulated groping, is more serious, especially because it was photographed. Franken's revenge was nasty, offensive, and in bad taste. On the other hand, it does not seem like he actually touched her, and how much groping could you do through a flak vest anyway - that's armor that can stop a 9 mm bullet even without the ceramic inserts she was likely wearing.

She suffered a humiliating insult, but if he didn't actually touch her, it wasn't sexual assault. And she admits that she agreed to the kiss.

This does not excuse Franken, but it would seem to suggest a significant difference from many other offenses we have heard about. Of course if this sort of thing was a pattern of behavior rather than a one-off, the arithmetic changes.

Baruk Khazâd!

Oddly enough, the word axes is reputed to be the only word in English which is the plural of three different English words: ax, axe, and axis. Though I think that it's a stretch to consider ax and axe as different words. Ax and Axis both trace back to Proto-Indo-European words that sounded similar and had their modern meanings, but I'm not sure if they were related.

So far as I know, the dwarvish 'Baruk' (Axes) is not related to the Hebrew 'Baruch', בָּרוּךְ, (blessed), which is related to the semitic word knee.

Roy Moore

Moore has denied the allegations against him, and his supporters have attacked his accusers. How about lie detector test all around? I don't have that much faith in them, but willingness to take one is often a good indicator.

Louis C. K.

I've never watched his shows or otherwise been a fan, so the very credible sounding accusations against him didn't surprise and dismay me in the same way learning about Bill Cosby did. It seems that Louis C. K. is connected with practically everybody in comedy, as friend, former writer, or mentor. Is it really possible that none of these people had a clue what was going on? The rumors have been out there for some time, and the victims apparently were telling friends, colleagues, and others long before they were interviewed by the New York Times.

I think that Jon Stewart, Jerry Seinfeld, Aziz Ansari and practically every night time host you ever heard of have some explaining to do. So far nearly all of them have kept their silence or been evasive or worse. Louis C. K. was Stephen Colbert's first boss in comedy and so far has been practically the only male to speak out at all.

A lot of these creeps are going to escape without any legal consequences, but at least they deserve public condemnation and being kicked off the airways.

Finally: A Good Election Night for Progressives

Big wins in Virginia, New Jersey, Maine, and locally, here in Las Cruces. Even the overwhelmingly victorious Republican congressional winner in Utah is a moderate replacing a right-winger.

AI Going to Take Your Job?

Kevin Drum opined that real AI is going to take everyone's job, but he thinks real AI is still decades away.

Like objects in your mirror, AI that can do your job is closer than most people believe. It may well be that AI with a general intelligence exceeding humans is a few decades away, but the fact is that most jobs in today's world don't really demand that much general intelligence. What they do require is some specialized intelligence, and we already have AI that has proven very good at that sort of thing. Your cab driver, your radiologist, your check out clerk don't actually need to appreciate Shakespeare or the NFL to do their jobs, they just need some knowledge in a specialized area.

I think that it's underappreciated that the big thing holding back robots today is not intelligence but sensors and actuators. Humans, and for that matter, ants, are equipped with rich suites of each. Progress in making small sensors has been very rapid, although the specialized intelligence required to interpret the data is still limited. Actuators are a bigger problem, especially the kinds of versatile and precise actuators that can be as rugged and precise as human fingers, arms, and legs. The capability of muscles to maintain themselves is hard to replicate.

Professional Courtesy

Rand Paul, Senator and opthamologist, purportedly was assaulted by a neighbor, also a physician, in their gated community in Bowling Green Kentucky.

The alleged assailant is said to be a pain specialist.

The Hertzsprung-Russell Diagram

If you were to understand only one thing about stellar structure and evolution, it ought to be the Hertzsprung-Russell diagram. It's a simple idea - a plot of the absolute luminosity (brightness) of stars against their surface temperature (often captured via their color, as measured by their relative brightness in two bands, the blue (B) minus the visual (V).) Below is a version, from the Wikipedia link, due to Richard Powell.

The most obvious feature of this diagram is the non-random distribution of the stars, with most of them being concentrated near a slightly curved line from lower right (low luminosity versus red color and low temperature) to upper left (high luminosity versus blue color and high temperature). This line is the main sequence, and consists of stars burning hydrogen in their cores, which is how they spend most of their lives. There is also a more diffuse blob of stars to the right of the main sequence, consisting of bright and cooler stars inhabiting the various types of giant categories. These have moved off the main sequence and are no longer burning hydrogen in their cores, and as their category names imply, are much larger than main sequence stars. Finally, there is another curve in the lower left of faint, hot stars, the white dwarfs, which are remains of stars having exhausted their nuclear fuel, and which have the mass of small main sequence stars but a million times less volume.

Note the vast range of luminosity among the hydrogen burning stars, from only one ten-thousandth of the Sun's luminosity to 100,000 times as bright, or nine orders of magnitude. The brightest stars are burning up their hydrogen a billion times as fast as the dimmest.

Making Fun of Fat People

A Pulitzer Prize winning columnist got in trouble for commenting on Huckleberry Sanders' weight. As a fat person, I suppose I should resent that. I mean there are lots of good reasons to knock her, like her incessant lying, slander, and ridiculous non-sequiturs. Should we really need to go after her fake eyelashes?

On the other hand, if we can't make fun of a person's appearance, what are editorial cartoonists to do? And Stephen Colbert's show might have to go to a half-hour format.

I'm probably insensitive and spoiled because my acquaintances seem to be polite enough to not knock my appearance to my face.

Football

Another former pro football star, now in declining mental health, has promised to donate his brain to research on CTE. His son was also a victim of football, a quadrapelegic as a result of a neck injury. They, like many other critics, believe that youth football, especially for younger players, should be banned.

Meanwhile, as every season, very serious football injuries continue to pile up.

One straightforward rule change could probably drastically change injury rates - ban unlimited substitution. Because of unlimited substitution, line positions in football are now dominated by 330 lb. behemoths who are so strong that they routinely injure others and themselves with size and strength. Current rules mean that they play in 12 second bursts for a small fraction of the clock time. If players had to play most of the game, offense and defense, with much shorter breaks, linemen would quickly get 60-70 lb (or more) lighter.
