We would think you were talking out of your arse. So I wouldn't tell us that, if I were you. 😉

Yes, it certainly looks as if "the Musk has slipped", as it were, and he has come out as the far-right cheerleader some of us were beginning to suspect. He is actually trolling the prime minister of a major western democracy, calling him "Two-Tier Starmer", a reference to a baseless claim circulating on the far-right, that British police show favouritism ("two-tier policing") towards ethnic minority protests. And, since Musk's own posts on X are given special prominence, he is spreading far-right tropes across the entire global ecosystem of X. Why would an American businessman - with zero knowledge of UK politics, but aware he is stirring up more trouble - do that sort of thing?

Newton was not "working with photonics". What you are writing is techy-sounding word salad. I think you may need medical treatment.

OK thanks. So I need to check every so often to make sure I know the one in operation. What about the other question: the reason my various devices seem to have individual public IP addresses, even though they are all fed by the same WiFi router? I had perhaps naïvely imagined the router would have a single address and that it would take care of sending the right data to the right device if several are connected. Is that not how it works?

This is all over the place. If you want anyone to take the trouble to read it, for God’s sake break it down by topic and post one topic at a time. Your comments about climate didn’t seem to make much sense and so the rest I have not bothered with, as it seems to be rambling. Not surprising, perhaps, if you are 88, but it won’t help to get you a hearing. By the way, if you are 88, you were born in 1936 so must have been 32 when you graduated in 1968. That’s pretty old for a 1st degree. Why did you take it so late?

Interesting. Do you know what causes it to change?

I was trying to find out my IP address, as a question to put to scammers calling me to tell me there is something wrong with my computer (heh heh, that should fox them). However I am now confused. I read there is a public, or external IP address, which seems to identify the WiFi router for the house and then individual, internal IP addresses for the various devices (laptop, tablet, phone) that communicate with the router. So far so good. I've found the internal address on my laptop, but when I look up the external one using whatismyipaddress.com , I get different answers for the laptop (Mac) and the tablet (iPad). Furthermore, the answer I got today for the iPad doesn't seem to be the same as when I tried this a couple of days ago, though it could just be my poor memory. At all events, from what I have read I would have expected the public, external IP address to be the same for everything using the same router. Is this not the case? And should this external address be permanent, or does it change when you reconnect each time or something?

Most decent pasta (i.e. made from durum wheat) needs 8-10mins in boiling water (up to 12min for some types, depending on the shape and thickness). Normally you use plenty of water, and a rolling boil, to avoid the pasta sticking to itself. Some people add a spoon of olive oil to the water but I never bother -just give it a stir once or twice in case any of it is starting to stick together. But I suppose if you heat from cold it starts to cook earlier, so you need less time once it starts to boil. I imagine the issue with that method, though, will be that the rate of heating until it boils, and therefore the cooking time, will vary, depending on how much pasta you cook, how much water you put in, the size of the pan, the heat of the hob etc. So you may find it hard to get the same results reliably unless you are always keeping all those variables fixed: same amount of pasta, same pan, same amount of water, same gas ring. Whereas if you wait until you have boiling water first, and then add the pasta, you can time it reliably as the cooking rate will be constant - water at 100C. I'd also have thought you might have an issue with it sticking if you heat from cold, as there will be no agitation until it boils. In summary, it may work for you but I'm not tempted to try. Being in the UK, I have an electric kettle to boil the water first, so I do that, tip it in, add the pasta and salt - and check my watch.

Commendable sentiments, Sheriff, but personally I don't think we should reward spammers, however congenial their politics.🙂

Intriguing, how does that work? What is this expansion from the smaller vessel? Water doesn't expand, surely? Is it not something to do with evaporation?

The Orange One is not a member here. Is there some point you want to discuss?

I came to the conclusion this person was a waste of space a long while ago and put him on Ignore to save annoyance. I recommend it.

Thanks. And here it is, for anyone interested: https://patents.google.com/patent/US11309735B1/en?oq=US+11309735+B1

Would you be willing to share the patent number and country in which it was granted? I’d be interested to read the description of the invention and the claims.

Who is "we" and what do you want to discuss? Or is this just spam?

Is Shapiro a real Likudnik, then? He can be Jewish and generally pro-Israel, yet still disavow the current Israeli government's Gaza policy, I'd have thought.

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.

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.........?

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.

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.

This comes across as just woo, though: the kind of “sciency”-sounding nonsense you get from people like Deepak Chopra. To say you use concepts from physics to “bridge the frameworks” sounds fairly meaningless and it is hard to see how it can be a sensible use of physics. Doing this, apparently without much grasp of what these physics concepts actually mean, will confuse your readers and make you look a fraud, even if your actual ideas have merit. What frameworks are you talking about and how does something from physics bridge them? Give an example.

Splendid. 👍 I know some people are a bit sniffy about using Wiki, but I find it’s often not bad for quite a lot of physical science, and it is pretty comprehensive. As for the half reaction of oxidising agents like dichromate and permanganate, I don’t think those are something you can expect to work out just by looking at the molecule, or ion, rather: I think you just have to know it, or look it up. These two are pretty common so it might be worth memorising them, including the number of electrons they gain. But whether you are expected to do this or not will depend on the course you are following.

You need to explain what this is. At the moment it is just a list, without any explanation. It has no content. Is it the layout of a proposed book? Or what?

IRECAP seems to be an obscure journal published by an outfit called “Praise Worthy [sic] Prize”, about which I found some amusing comments: https://sites.massey.ac.nz/library/2013/01/23/good-guys-bad-guys-and-open-access-journals/

Yes, but the claim I am challenging is not a "detail". It is the core of your idea. If you want to change the meaning of "complexity" to something so far removed from most people's understanding, you need to have a solid argument, otherwise the whole idea collapses.
