Cancer Posted December 21, 2020 Report Share Posted December 21, 2020 You could set up a lab to measure it. Otherwise set up a simple model where you can estimate it. I've never seen one cracked open to see what's inside. Pariah 1 Quote Link to comment Share on other sites More sharing options...

The moment of inertia of the fidget spinner will depend heavily on the design and mass, of course. We wound up with about two dozen different types during the height of the craze.

Pariah Posted December 23, 2020 Author Report Share Posted December 23, 2020 Yeah, nothing is more of a dead giveaway to academic dishonesty than identical wrong answers. 16 hours ago, archer said: @Cancer West Point adopted remote learning following spring break during the last academic year due to the coronavirus pandemic.

Pariah Posted December 26, 2020 Author Report Share Posted December 26, 2020 I've just had the most brilliant (if evil) flash of inspiration. When the day arrives that I finally have more money than I know what to do with, I'm going to hire private investigators to follow up on the lives of former students who have been particular PITAs. When the children of those former students turn 6 or 7 years old, they will be getting an anonymous birthday gift from me: A drum kit. Thus will I have my revenge. Ternaugh, tkdguy and Logan D.

Tangentially along the same lines: My old family doctor closed her practice back in May, and I finally got around to getting a new one; the intake appointment was the morning of 12/31. We worked out during the appointment that he took my pre-med physics course from me back in Winter of 2007 or 2008. We shall see if he feels the need to extract revenge.

Pariah Posted January 13, 2021 Author Report Share Posted January 13, 2021 I gave some of my students an assignment to research the causes, effects, and solutions to the Salt Lake valley's annual inversion problem. In reading the responses, one group jokingly suggested as a solution "Blow up the mountains so we get better air flow". And I found myself thinking, "Yes, go on...." Logan D.

Cancer Posted January 14, 2021 Report Share Posted January 14, 2021 Back around 1990 there was an idiot of a mathematician somewhere who suggested that cyclic orbit or obliquity or something changes of the Earth were partly to blame for the climate change effects we were seeing (that's not that far-fetched, but I don't think that's a leading factor), and that the Moon caused those (true, at least some of them), and he suggested we blow up the Moon and get rid of it. That around the time I was getting to know future in-laws, and in one of those conversations my step-father-in-law-to-be mentioned this guy and asked what I thought of his idea. My response was, "What's he want to do with the f***ing pieces?" tkdguy 1 Quote Link to comment Share on other sites More sharing options...

Since the majority of the wealth of the world is in the northern hemisphere, it would make sense that's where most of the sales would be Then in a few years, he could come up with some brilliant solution to solve the Earth being too "top-heavy".
