  1. Not sure what you mean.Our brains have no choice but to extrapolate from past data to create a "virtual present" and a likely future. Our brain processes are not instant and that is how we and every entity ,a;live or non-sentient live. It is "freedom within boundaries" . As the expression goes ,time is what stops everything happening at the same time.(or words to that effect) edit "“Time is what prevents everything from happening at once.” John Archibald Wheeler https://www.goodreads.com/author/quotes/30075.John_Archibald_Wheeler
  2. As the "time slices" of the brain become theoretically smaller (approach zero) the amount of energy required to process data approaches infinity (=impossibility)Our brains can observe the world for the very reason that we cannot do that(grasp the "present")
  3. We all make mistakes and hopefully learn from those mistakes. We cannot know everything and have to apply our resources to those things that we can most accurately know and which are likely to be most beneficial or of most consequence. If something is unclear to us we can investigate further and it may become clearer.
  4. This Smotrich guy? https://www.google.com/amp/s/www.aljazeera.com/amp/news/2023/12/31/israeli-minister-reiterates-calls-for-palestinians-to-leave-gaza Not the Defence Minister-the Finance Minister and excluded from the War Cabinet from my cursory knowledge.
  5. Think you are reading too much in to it. Myself otoh bought one of Cleese's books *(and I might buy just one or two books a decade) and was unable to "read into it" more than the first 10 or so pages ,so earnest it seemed to me. Well my concentration/absorption levels have dipped the last good few years (I felt the same about Hemingway who I also thought would be an interesting read) * Life and How to Survive It https://www.thriftbooks.com/w/life-and-how-to-survive-it_john-cleese_robin-skynner/637920/#edition=2384136&idiq=15047948
  6. Some strange brew going down in this thread,man https://www.youtube.com/watch?v=hftgytmgQgE "A witch of trouble in electric blue" yes ,blue crockery does it for me.
  7. That is because it is (apparently) only of very incremental interest to the consumer of the beverage whereas the cultural significance of the drinking of the tea is far more important. There is also the humour involved in the Boston Tea Party where the English and the Americans are free to have a good laugh at each other if they want to. You kicked us out of your country using the "tea issue" at the outset but we are the ones who (in our minds at least) actually know how to use the stuff. Any coincidence that the phrase "a storm in a teacup" is still fairly widely used? The Japanese also hold tea in high estime(not so sure about other countries) Don't see what "pushback" you mean. I am sure it may well make a difference in the taste but ,personally speaking I have never added sugar to tomatoes even though it is well known that it makes it taste better and is often recommended in recipes.....
  8. But tea (-making)is a social occasion ,a ritual of sorts I always felt. Do you offer up warmed up old tea to your friends and visitors?
  9. Are you quite sure there is no Muscovite Mica in the building blocks? Salt can be an insidious menace that builds up and crosses boundaries over time https://www.thejournal.ie/mica-explainer-5467214-Jun2021/
  10. I have heard some of the sugar cubes imported via Canada may have been predoped with a sodium substitute.
  11. Be careful not to get culturally expropriated.Don't put on a checked shirt and camera for the tasting session.
  12. Back in the 60's our school teacher told us not to overstew tea because ,after a few days it contains arsenic! I already mentioned this school teacher to @TheVat. in a previous, completely unrelated thread. He had been held in a prisoner of war camp (shot down in a bombing sortie) in Germany ,which might explain how he came to have such apparently arcane knowledge.
  13. I must have gone 60 years without going near a tea bag for various reasons but have adapted to the habit as some of the new flavours available in green teas only come with bags. I can't say I notice any taste from them and I don't know about nano particles -I throw the bags ,along with the coffee filters into the "donkey bucket" and have always supposed they are made from something compostable. The coffee filters,especially are the thing they go after first. Otherwise cabbage leaves are popular ,but I don't stand and watch-they never touch the grapefruit halves or ,obviously lemons. I seem to remember the French hadn't a clue about making or serving tea and we used to be given a cup of warm water with a tea bag either in or beside the cup when we went into a cafe back then. They probably pitied us for needing it in the first place.
  14. "Britain’s media has reacted with fury and bewilderment after a US scientist claimed the perfect cup of tea is made with a pinch of added salt" https://edition.cnn.com/2024/01/24/travel/britain-us-scientist-tea-debate-intl/index.html Apparently a soupçon of salt takes away the supposed bitterness of the drink of tea. I can't see that catching on but then I myself drink very ,very weak green tea (obviously no milk -also no sugar) I was never aware that bitterness was a problem with ordinary black tea but perhaps there is to some.
  15. Thanks. Is it possible for two particles to collide without new sub particles being created ? Does "particle dodgems" or "particle pinball" exist in practice? Can one particle influence the trajectory of another without the fireworks? (do their waves just superimpose in a continuous way?)
  16. That example occurred to me after I had asked the question. So the particles collide and as a result new particles result. Do they accelerate away from the region where the "parent" particle was? Or do they travel like a photon ,either at zero velocity or at c? If the latter then they don't accelerate and the acceleration as in "particle accelerator " is a classical process. That is why I put it in quotes.As "comparable" as possible ,I suppose. Are there any situations where a quantum system undergoes anything like what a classical system does when it is subject to accelerating forces? I think you are saying there aren't? Is it possible to treat a quantum particle (system?) classically? Does that introduce error?
  17. Are there examples of how acceleration is treated in quantum theory? If a classical system is accelerated I have a picture of a wave traveling through the system like if you were to pull a string or push a rod. What happens in "comparable" situations when the systems are quantum? Does "acceleration" mean anything under those circumstances?
  18. What is that supposed to mean ? Are "you" in a third frame of reference or in A's or B's?
  19. In which frame of reference?
  20. A cricket commentary as reported on a facebook account(the late Brian Johnson) "Sometimes, unintended humour can be the best. The late Brian Johnson was a star performer when on Test Match Special. He once remarked innocently, ‘the batsman’s Holding, the bowler’s Willey.’ When he realised his statement was hardly appropriate he had a fit of giggles. It still makes me smile. Not what he said, but his reaction to it" There was all this too (gaelic games commentaries of old) Legendary witty GAA commentator Mícheál O'Muircheartaigh is an active 93. Thanks to Ferghal McCarthy for these live gems. -Sean Óg Ó hAilpín: his father’s from Fermanagh, his mother’s from Fiji. Neither a hurling stronghold. -Anthony Lynch, the Cork corner-back, will be the last person to let you down – his people are undertakers. -The stopwatch has stopped. It’s up to God and the referee now. The referee is Pat Horan. God is God. - Brian Dooher is down injured. And while he is, I’ll tell ye a little story: I was in Times Square in New York last week, and I was missing the Championship back home. So I approached a newsstand and I said, “I suppose ye wouldn’t have The Kerryman, would ye?” To which, the Egyptian behind the counter turned to me and he said, “Do you want the North Kerry edition, or the South Kerry edition?” He had both – so I bought both. And Dooher is back on his feet… Colin Corkery on the 45 lets go with the right boot. It's over the bar. This man shouldn’t be playing football. He’s made an almost Lazarus-like recovery from a heart condition. Lazarus was a great man but he couldn’t kick points like Colin Corkery. Teddy McCarthy to Mick McCarthy, no relation, Mick McCarthy back to Teddy McCarthy, still no relation. I saw a few Sligo people at Mass in Gardiner Street this morning and the omens seem to be good for them. The priest was wearing the same colours as the Sligo jersey! 40 yards out on the Hogan Stand side of the field, Ciarán Whelan goes on a rampage… it’s a goal! So much for religion. He grabs the sliothar, he’s on the 50! He’s on the 40! He’s on the 30… he’s on the ground! Pat Fox out to the forty and grabs the sliothar. I bought a dog from his father last week. Fox turns and sprints for goal… the dog ran a great race last Tuesday in Limerick… Fox, to the 21, fires a shot – it goes to the left and wide… and the dog lost as well. In the first half, they played with the wind. In the second half, they played with the ball. 1-5 to 0-8… well, from Lapland to the Antarctic, that’s level scores in any man’s language. Pat Fox has it on his hurl and is motoring well now, but here comes Joe Rabbitte hot on his tail… I’ve seen it all now, a Rabbitte chasing a Fox around Croke Park. Here’s another I recall; " Jimmy Barry Murphy. Jimmy Barry Murphy. One of the ten. The ten who have won All Ireland Hurling and Football Senior Medals. He will be spoken of till the end of time”. Teddy looks at the ball, the ball looks at Teddy… Mike Houlihan for Limerick. He had his jaw broken by a kick from a bullock two months ago. He’s back now. ‘Twas some bullock that broke Mike Houlihan’s jaw!
  21. Looking at it physically ,the light from P's nose recedes from him at c .He follows ,whilst outside the EH at <c You say he "catches up" with it .Is that because the light from his erstwhile nose radiates in all directions and so he "catches up" or "falls into" that part of the light that is not receding directly away from him but with a component back towards him?(which is red shifted?) If there was just one photon receding directly along his "line of site" he wouldn't even see it red shifted?
  22. Very far from understanding this but can I ask ,if the up and down coordinates that apply outside the EH are replaced with future and past inside the EH what are the future and past coordinates that applied outside the EH replaced with inside the EH? Are there any spatial coordinates that apply inside the EH and can they be visualized? They wouldn't be flattened on the EH itself ,would they? (that's a wild ,desperate guess)
  23. This seems a silly question ,but if two objects follow each other through the event horizon of a very large BH ,does the second object see the first object as it passes the EH? Even if the two are very close together... Alternatively would a Pinocchio lose the sight of the end of his nose first as he passes the threshold?
