Pariah Posted March 11, 2022 Report Share Posted March 11, 2022 I had a course in my master's program that was titled Modern Physics, eg, special relativity and quantum mechanics. The quantum mechanics part wasn't too big a deal, since I had taken it as an undergraduate and have been teaching the very basics of it for years (atomic structure, specifically). Relativity, on the other hand, was a little harder to wrap my head around. It was no less so because the professor chose to teach it with matrices rather than differentials. I literally hadn't done anything with matrices since the Bush administration. The first one. Quote Link to comment Share on other sites More sharing options...
Cancer Posted March 11, 2022 Report Share Posted March 11, 2022 In the last few days I've had to introduce the vector cross product in my mechanics class, and only 2 of the 40-minus students in that class have had any linear algebra. This makes the conventional 3-by-3 determinant form for computing the cross product ... problematical. Quote Link to comment Share on other sites More sharing options...
Cancer Posted March 23, 2022 Report Share Posted March 23, 2022 Yesterday morning there was a large possum in the yard. Possum and Fluff Butt were not entirely sure what to do about each other; the possum was taller at the shoulder than Fluff Butt. I brought the cat in.

death tribble Posted March 28, 2022 Report Share Posted March 28, 2022 Regarding Will Smith striking Chris Rock, this has been coming. Not particularly from Mr Smith or to Chris Rock but someone snapping and striking someone at a ceremony like this. I'm only surprised that has not happened before with the American penchant for Roasts as popularised by Dean Martin. Quote Link to comment Share on other sites More sharing options...
Cancer Posted March 30, 2022 Report Share Posted March 30, 2022 I have decided that I am going to ignore that incident and never learn anything about it, as a direct expression of how little I care about show-biz personalities and the horses--t they can get away with because they are famous and charismatic.

Cancer Posted April 3, 2022 Report Share Posted April 3, 2022 Something I don't think I've passed along here is that Fluff Butt drools when he purrs, especially when he purrs in response to being petted. I'm not used to drooly cats, but I have one. Quote Link to comment Share on other sites More sharing options...

Cancer Posted April 6, 2022 Report Share Posted April 6, 2022 The site where the following was originally "published" is now gone. It's just about twenty years exactly since that posting, and it seems like time to hang this out there again. For reference, "DDR" = "Deutsche Demokratische Republik", what the old East German government called itself. Spoiler Sometime in probably 1963 or 1964, not that long after the Berlin Wall went up, there inevitably came a time when the DDR started letting people out, people who were of no real value to the state. But the DDR might possibly gain some propaganda points if they released them to the West for at least a while, and more still if they could be got off the public dole. If the story related to me is accurate, the first was a little girl. She had been orphaned, and was being released to go live with her grandparents in the West. The details of the release were somewhat delicate. An unmarked civilian car was to be driven by an American civilian through Checkpoint Charlie to a specific place inside the Soviet Sector. The girl was to be let in the car, and the car was to drive back through. Sounds simple enough, but since this was the first time this kind of thing was to happen, there was substantial doubt about the mission. Even if the driver was completely above board -- that is, completely without attachments to the US Government, including all its intelligence operations -- it could not be guaranteed that he wouldn't be seized as a spy and imprisoned on trumped-up charges. That kind of thing supposedly had happened before, depending on whose side of the Cold War propaganda you believed. If the driver was imprisoned, execution was considered very unlikely, but it couldn't be ruled out, either. So, the driver had to be a civilian. He had to be completely without ties to US federal agencies in any capacity (because the Soviet and East German intelligence agencies were pretty good, and it had to be assumed that any cover, no matter how good, would be penetrated). And for safety (state safety, not his personal safety, of course) he had to be someone who really wasn't at all important to the strategic situation. In short, he couldn't know anything, and as far as the US was concerned, well, if he was seized and tortured, it would be too bad but it wouldn't really matter. The word is "expendable". The man selected was on the bottom rung of the American Red Cross office in Berlin. His only government papers were his passport and his discharge from the US Army Air Force about a dozen years previous. (He'd been drafted, like most young men of his age, and had been lucky enough to serve his duty during that narrow interval between the end of World War II and the beginning of the Korean War.) He'd been with the Red Cross for four or five years, and in Berlin since August 1962. As it happened, the release went off without a hitch. Approach the gate at the scheduled time, present papers, get waved through, drive in, stop, girl gets in, turn around, approach the checkpoint, get waved through again, back out to the American Sector and safety. Just a little extra wear and tear on the nerves leading up to the event, both for him and his wife; he wasn't a stupid man, and it's easy to draw conclusions about what your government and your office boss think about your value when you draw that assignment. He never did tell his children about it, since at the time (the oldest of them was seven or eight) there was nothing they could do but worry, and by the time they were able to understand he had other things to talk about. His sons didn't learn about it for nearly forty years, and even then it was from his widow. Goodbye, Dad. Pariah, Old Man and L.

Cancer Posted April 18, 2022 Report Share Posted April 18, 2022 OTOH, around midday we went to lunch at the waterfront, and watched otters saunter down the dock between the boats. If we read the signs right, the otters' den is under, or at least adjacent to, the building in which we ate. Also saw deer, a raccoon in the back yard, and an eagle in a tree not far from Point Wilson. Quote Link to comment Share on other sites More sharing options...

Cancer Posted April 19, 2022 Report Share Posted April 19, 2022 Aaaaaand ... Lost last weekend as father-in-law fell and broke his femur on Thursday morning, resulting in a hospital trip, compounded by a mishandling when they had to catheterize him, resulting in blood clots somewhere that make peeing much more of an adventure than it should be. He's still in the hospital. Hopefully will go home late today. Then ... I arrive on campus this morning about 0800 my time and there is much noise and chaos. Seems there was a (mistaken?) fire alarm and water got into all the Physics Department offices and labs. Damage is still being assessed, and they have all the windows and doors open to aid the drying-out process, so it is butt cold in there. I had office hours starting at 9, so I left a sign on my office door and set up in the library (where I've had half a dozen customers). I'll head down in half an hour or so and see what's happened to my stuff. I realized that there is a gaming application to all these experiences. I have come to the conclusion that the usual interpretation of buying multiple levels of Unluck is incorrect. Much of the time nothing happens, and it looks like free points. However, at intervals you have episodes where multiple independent misfortunes strike nearly simultaneously, so you must contend with a collection of bad stuff all at the same time. In my younger days my expression of this was the succinct "Badness comes in waves," because yes, it does. That this could be translated in a game mechanic is a novel thought, brought on by thinking about how I'm going to be kept out of gaming lunch this week.
