  1. But also note that it is people who view themselves as powerless and their actions as relatively insignificant that are prone to take the least responsibility for the consequences of those actions. When you get a great deal of people who are reacting to their lack of power and acting irresponsibly, the effects can be greater than when the strongest-willed individuals pursue their goals with everything they can muster. Generosity and kindness are sometimes performed to garner the social power that comes with gratitude and respect. This is not to say that these attributes are always de
  2. First off, hello to those who remember me from when I used to participate in the forum regularly. I was reading the book, Hitler's Scientists, by John Cornwell and another book was cited (can't remember the name of that one, sorry) that credited Heisenberg with the ethical feat of preventing Nuclear weapons from being developed by the Nazis first. This sounds as if Heisenberg was being lauded for obfuscation. Do you think this is a valid interpretation of the role Heisenberg played in the practical development of nuclear technologies?
  3. Ok, then subtract my posturing from the content of my posts and see how much of what I say is substantive vs. how much is oriented toward defending against personal criticisms not substantively oriented. I think you'll find that my orientation is primarily substantive and only becomes personal where personal attacks were initiated by someone else. I'm not claiming to be perfect but I strive to avoid interpersonal bickering because I've had enough bad experiences with it to actively avoid it. This doesn't mean I want to let people walk all over me either.
  4. Subtract your belligerence from your posts and what is left? You may be very good at expressing mathematical physical concepts but the rest of what you say is really just posturing and bullying. Are you familiar with the psychology of authoritarian personality?
  5. Um, my point was that technological progress has deprived people in cold climates of the natural function of manual labor to generate body heat. I don't know what feeling guilty and building windmills has to do with it. Waste-heat generating factories evolved into a culture of waste-heat supported relaxation, even as the factories were being automated or exported. Still the culture/demand for warmth continues, only now there is less association between heat and labor. So heat has become a product instead of a by-product of industry. I think you could say that warmer climates have also bec
  6. I'm not saying anything about the relationship between mass and weight except that weight represents the force of a mass due to gravity, i.e. the same object with the same mass weighs less on the moon than on Earth although it has the same mass because the acceleration of gravity is different.

    That's a good point. That's what turned me from being a Bush critic to a Bush-supporter. I don't know if this effect is as common-sensical as simply distancing oneself from what popular opinion deems hated. It is popular to support a popularly recognized underdog but unpopular to support a person deemed a popular enemy (that is my impression anyway). It obfuscates a lot to avoid calling hate "hate." I think I am reasonably neutral when evaluating the media treatment of public figures. When I see snickering in the chastizing of Sarah Palin, it is not because I love her and want her t
  8. I have heard various reasons given and I don't know which are speculation or not. Regardless, I don't see any reason why an individual should be punished, let alone crucified, for expression. On thing that is clear is that the crowd requested Pontius Pilate execute Jesus because they said their laws didn't allow it. That is blasphemy of Holy Spirit. If you sincerely believe in a law, you don't seek someone else to break it for you because you're not allowed to.
  9. Yes, I've been chastised enough times by Swansont for thinking classical mechanics into quantum matters. However, the electrons are still attracted to the nucleus by electrostatic force, which means that moving them away from the nucleus requires counter-force, right? It just so happens that the amount of energy/work required to get them to move is specific to their quantum conditions, right? But isn't a potential difference a force impetus in the same sense as mass and distance create a gravitational force impetus? My whole point with this was to address questioning as to how
  10. What causes the spark? The light is emitted when electrons are excited and de-excited to release the energy as photons, right? So what was the force that had to be overcome to excite the electrons? Their electrostatic attraction to the nucleus, right? So isn't the electrostatic force holding the electrons to the nucleus the force that resists the current? Isn't the reason conductors conduct easily that their conduction-band electrons have to overcome relatively little electrostatic attraction to change levels? Yes, I agree with this. Weight is like electromotive force, if I underst
  11. You've called me ignorant and told me to read a physics book enough times now. Now could you please restrict your criticism to substantive aspects of my posts instead of your general impression of me (whether you call that ad hom or not)? If you don't have the ability or patience to read the content of a post I write, that doesn't automatically mean you should start ranting about how you're a physicist and I'm not. If you do read the content and you have critical insight about why something I said is wrong, I'm happy to learn from your insight. The insults get old, though.
  12. Thank you for your book suggestions. I don't think they have those at the public library I use but I'll keep my eyes open for similar titles. "Intensity" may not be your term of preference but it is English and commonly understood. I am more concerned with the content of what is said than the style of saying it. Writing style aesthetics is not physics, btw. "Magnitude" is a term I'm familiar with but I don't know what it refers to empirically. It sounds abstract. "Charge density" sounds less abstract but what does it refer to exactly? In a conductor, there are conduction band electrons
  13. Why not then? Gravity is the force with which the object pushes down. As long as it is pushing down, it has the potential to move in that direction whether it is actually moving or not. So its potential energy can only be measured within a frame of motion that you apply BUT its actual potential to move is present in the force it is exerting, which is empirically observable/measurable as weight. Energy is the capacity to do work, right? Isn't force a capacity to do work as long as it is consistent over the distance of work to be done? I see your point about the existence of pote
  14. For the record, I would not claim to be above reading any physics book. I read them often, in fact, along with other sources and I read posts on this forum with great interest as well. My weak point is mathematical language like "scalar fields," which I sometimes google to try to understand but often I find what was expressed in terms of expensive mathematical language could have been expressed in simpler empirical terms once I do understand. No matter, I do try to learn more by reading posts with unfamiliar language and decoding it slowly and painfully sometimes. Other times, I remind mys
  15. What empirical references does this post contain? Conduction-band electrons in a conductor transmit waves of pressure. When they reach an insulator, they attempt to transmit their energy through the medium. This could cause the shielding of a wire to melt, air to spark, etc. A heavy enough truck parked on a weak enough bridge will also cause the bridge to collapse to allow the truck to continue expressing its potential as kinetic motion of falling. What word describes the strength of charge intensity besides voltage then? My understanding is that the behavior of electricity in condu
