  1. Y’all woke libs! Kill DEI! Trump 24! Bumper sticker simplicity better than policy point precision in elections

  2. I will be super clear: If it helps Kamala win WINVAZ PAGAMI (my mnemonic for the essential swing states), I would be all in for a rabid hyena named Beelzebub who digs up the corpse of Mister Rogers and buggers it on national television.

  3. I'd be more interested in how you say you "harvest" a wattless current, 90deg out of phase with voltage, onto a different circuit and make it do work.

  4. I wonder how that would go... "At least Trump does it himself and doesn't leave it to subordinates!"

  5. +1 In my opinion History is a subject that shoud be explored when the 'student' is read, not some collection of vaguely related facts and figures rammed down a child's throat for an examination. Having spent my working life addressing the questions 'what do I need to know or figure ?' in order to get this answer or that result I am finding in retirement the pleasure of exploring the questions ' How did we get there and what insights can be gained from this knowledge?' I think that these insights may well be more valuable to pass on that say the details of the aerodynamics of biplanes, which knowledge in near obsolete these days.

  6. Ok, I've finally come to understand that my repeated assertion that the falling observer in Schwarzschild and Lemaître coordinates needs to resynchronize his clocks was incorrect. Let's approach the problem from the other side. So, the falling observer does not need to resynchronize his clocks for the speed of light to remain isotropic. This means that the light cone actually tilts as one moves through a gravitational field. Only the coordinate system that accounts for this tilting in the necessary proportions is a physical coordinate system. The key point to understand is that if we accelerate but do not need to resynchronize our clocks, it means that the light cone tilts. In special relativity, it's the opposite: when we accelerate, the light cone does not tilt, and it is necessary for the moving observer to resynchronize their clocks to maintain the isotropy of the speed of light.

  7. Indeed. When one looks at the history of Rome, it evolves from a monarchy to a republic and then mutates into dictatorship. Ring any bells.........?

  8. That's good. I'm becoming more interested in history as well. I never used to like it at school. I've sort of realized that we need to know where things came from in order to know where things are going.

  9. Well he has his ambitions too: He's getting good grades at St. Andrew's, in between mountaineering expeditions in the Highlands. I think he just wants to do things on his terms and carve out his own arena of expertise - very much as I did when I was his age (my mother read English so both my parents were on the arts side) The nice thing is that as I get older I become more interested in history, so I can ask him about things, which makes for a degree of academic mutual respect.

  10. Yes I sometimes have pangs of guilt wondering I put him off the sciences in some way. Both of his parents were on the STEM side, his late mother having been a graduate of the École Nationale des Ponts et Chausées (though really a mathematician at heart - she later did a PhD at MIT on waves). He took physics as part of his International Baccalaureate and did OK, but dropped chemistry after GCSE. From him I learned something interesting: chemistry is in some ways harder to grasp at the school level than physics (so long as a bit of algebra doesn't faze you) or biology. It has the abstraction of physics, but there is also a lot of "stuff" to just learn: the Periodic Table and the behaviour of all these different elements and compounds, not much of which seems to relate to tangible things. At least with physics you can calculate the trajectory of a cannonball, or understand the motion of the planets. Anyway I think he wanted to plough his own furrow and he has always been interested in the ancient world. As a matter of fact both my father and his father were historians.

  11. Based on some new information I think you're right. New polling data shows her gaining in some swing states but not Pennsylvania, however she is due to attend a campaign rally in Philadelphia and is expected to attend with her VP pick who will be announced there. Why announce in philly if you're not going to pick Shapiro? Would be like visiting the Catholic part of Glasgow and saying you're a Rangers supporter. Dead on arrival! No way she'd be stupid enough to kick a swing state in the teeth like that.

  12. More generally known as the principle of cussedness: these are laws by which nature opposes an attempt to change to the system.

  14. The examples are in the implications. Mass is seen as talent while energy is seen as tendencies that lead to impact, the conversion is represented by the constant c and represents the efficiency of converting talent to impact. You can say why must it be in physics, and the answer is that it does not have to be but I chose it to be so that it may be more digestible, though it seems that I made it less digestible. Look. I am not claiming to have something to publish in some journal. I understand the limitations. I wish that I learned to play the piano so I could just make up random nice-sounding sequences and not need the rigor of dozens of pages. As it turns out I did not learn the piano but I still have a creative mind that will not stop reasoning so I share the frameworks that I think of. You can say it does not have rigor and I agree but I am hoping for more of a discussion, not offense thrown at me.

  15. Firstly, he isn't going to reply. But you've put a lot words into your effort and I've got a short attention span; so if you want an answer, would you be so kind as to summarise your main point, and we'll go from there. 🙂
