The premise is straight forward: A physicist from 100 years in the future grants a serious Q&A with physicists of today by issuing tickets whereby the questioners had to choose to attend one of three consecutive one hour sessions, A, B, or C. The physicist from the future tells everyone that he...
An interesting aside to the question: what if space did stop expanding suddenly? What would be the effect on visible objects like galaxies and black holes?
My takeaway is that an accomplished physicist and mathematician presented a detailed scientific theory and over the next thirty years of discovery and greater understanding, his peers showed the theory to be wrong. I see this as an example of the scientific method, progress, and the bravery of...
In 1994 Frank J. Tipler wrote a book titled: "The Physics of Immortality" which appeared to suggest that physics and religion could be united. Absent religious or anti-religious prisms, if the universe were found to be closed (I know, it's not), is Tipler's physics worthy of serious consideration?
I would like to subscribe to a general science periodical (emphasis on physics would not go amiss) other than Scientific American that would explain new scientific discoveries and ideas in popular terms. A hard copy magazine best but digital okay too. Please, no defense of Scientific American...
The effect of the southern hemisphere does effect the Coriolis force when the water moves but laying the sweatpants into the drum with the leg opening opposite the way we did in the northern hemisphere will result in the same effect. It’s the tangential force on the leg opening which, we know...
Pocket mystery solved. The pockets in the sweatpants are left inside as in normal use before putting inside the washing machine. The pockets are turned inside out in the washer--not the dryer. Given that the pocket material is thinner than the pants material it must be that hydraulic forces...
Tom, Only the pockets on my sweatpants and lounging pants turn inside-out. I will try two experiments: 1. I will turn the pockets inside-out first, as you suggested. 2. I will turn the whole sweatpants inside-out. I'll let you know how the experiments turn out. As an aside, the pocket material...
Right up there with Dark Matter is the observation that the pockets in my sweatpants turn inside out in the dryer. My go-to guy is ChatGBT and he said: "The pocket openings getting caught on the drum edges will not directly cause them to turn inside out. Instead, the pocket linings can get...
Awhile back there was a discussion about the following scenario: an astronaut sets free into space outside his window a round magnet so it just sits there a distance away ensuring the spaceship has no effect on the experiment. Then he wafts out gently a large pail of tiny iron filings and dust...
It occurs to me that AI would be unable to think something that is easily explained mathematically could still seem spooky and deserving of more thought--something maybe not quite right. I don't know if this is a weakness in humans or in AI.
Quite right, Ibix. I'm afraid I've expressed myself poorly. I, and we all, trust the mathematical models accepted by the community. My now elusive point was, and is, that I have an admittedly primitive emotional feeling about it over which I have no control to feel--but total control to ignore...
"So your concern is that you can grok it piecemeal but cannot grok it in fullness. Yes, at some point we all have to "shut up and calculate".
Yes, well said. If we are honest we must all end up at that point in our education though for most here it will be a bit further along than than the...
