  1. A good example if one were to plot the probability function for the quantum uncertainty principle. One wouldn't get a bunch of wavy sinusoidal lines. It would look more like a probability cloud around a vacuum potential baseline One of the most common mistakes is people trying to draw a particle wavefunction is to draw a symmetric sinusoidal waveform. That looks nothing like what a detector would show for a particles wavefunction. Another highly inaccurate visual representation is spacetime drawings. They are never accurate. Hence pictures are useless they are never accurate. Accuracy comes from making plots of test results. Not random drawings.

  2. At the risk of being thought racist, I would NOT trust a video from the Indian subcontinent showing somebody putting a screwdriver into an electric socket. When I was in Dubai we were constantly stopping people from that part of the world from doing dangerous things with electricity. Their safety culture around it seemed non-existent. You can safely send sparks between people if you have a van de Graaf generator, but don’t even think of doing anything involving mains electricity.

  3. They don't if anything a physicist would take one look and completely ignore it. Just as I did. So am I sounds like a good time to close the thread

  4. Many Englishmen get through a litre or more of tea each day, of course. But not in one go.

  5. Time is relative to the frame of reference of the observer, being affected by speed and position in a gravitational field. Aging is a more nebulous concept. As Phi notes, it’s probably a biology issue, so you should specify which concept you wish to discuss. Aging does not affect time. Time affects aging.

  6. That's because French dinners are social occasions. They don't eat that much, generally. In fact, one benefit of that style is that there is plenty of time for one's system to react and send a signal when you have had enough. (My late wife was French, so I have some experience of family gatherings.) I understand that one factor in obesity can be the bad habit of wolfing down food very quickly, as it takes time for the body to react to the amount of food consumed and send a "full" signal. So if one eats fast, one runs the risk of overeating. A slow succession of small courses, in which ones chooses how much of each to take, is far better from that point of view. I doubt that anyone in France (apart, perhaps from Obelix, who is no role model) would drink a whole litre of milk in a few minutes. It would be thought rather barbarous, I suspect. The French are a lot slimmer than the Americans - or the British.

  7. Remember those five diagrams....if not the explanation...I hope they will defend themselves for a long time to come...they are easier to visualize,when writing pages and pages of mathematics becomes hectic...let's have the spirit of making science accessible and universal to the crackpots,laymen and strawmen and to the majority without degrees in physics.

  8. It is seems I don't know what to say...what am doing is not some kind of a movy or a video...look at this.... Am NOT wrong...you refuting those diagrams you ARE dead wrong...that single diagram....its just a wonderful summary...of how many physics mathematical formulars? Just count. You want to make me think am hallucinating...am not ... simplicity make science accessible to the masses just like a simple formular E=mc^2.

  9. If that is the notion...good luck while you try to look for answers about issues of the Universe like baryogenesis...hope you won't take forever.

  10. The red marks/ticks won't change what is the reality....17 February 1600 Giordano Bruno burnt for going against the establishment of his time.... always happen when people forget history,and become overconfident of themselves that they can not stomach challenges... nothing new.

  11. I was going to let this, less than gracious concession, go; but then your friend gave it a lil green 1, and I'm WTF. The implication seems to be, I'll say this to placate the fool; who asks questions I can't answer... So my question to your like happy friend is, what's up with that/please explain yourself?
