Your 2021 UNESCO map seems pretty similar to the one I posted, just a tad more colourful. It certainly bears out all my comments. I fail to see the relevence of any of this to any part of this thread. Please stay on (your own) topic.

My apologies to Olorin I see I have called you Mitko by mistake. Mitko is another member posting a thread about an entirely different subject.

Your summary of standard relativity physics started well. But you then introduced circular arguments a couple of times. If time is merely a human notion then the concept of life span is equally meaningless, voiding your conclusion. Once again if you reject time then you must also reject frequency as a form of time, voiding your alternative proposal.

But I like your smile so excuse accepted.

The term 'Carbohydrates' is strictly (c.H2O)2 in Chemistry. However this creates carbohydrate 'units' which form the basis or backbone of many bio-molecules. These are therefore part pure carbohydrate, part something else. Sugars and so forth are pure carbohydrates, but the bio-molecules are not. So the preparers of the food are giving you the % in terms of bio-molecules and in terms of those parts which are pure carbohydrate.

Therein lies the twist in the tale. which way does current flow in a complete circuit?

I was not arguing with your call for evidence. I was commenting on your attribution of Mitko's words to my poor self.

I think I said there are two electrical sign conventions and one magnetic - which makes 3 in all. Since I posted my reply within a few minutes of Mitko posting his OP, I am disappointed he has not responded.

That is an unevidenced claim. You need evidence for that. I somehow don't think you meant this.

Actually the plus and minus conventions are more subtle than you perhaps imagine. There are actually two binary ( +/- ) sign conventions involved in electricity which have opposing sense, and yet another if magnetic effects are also included. The net result of this opposition of sense is that whichever way round you choose there will always be this difficulty.

Yes, of course I do. My long memory also recalls the row over the US 'the need to know' agreement. And I notice that they are cooperating not with their staunchest ally, but another party. Well done the Koreans.

Perhaps you should consider receiving some geological instruction rather than offering personal insults to others. Here is a map of the Pacific 'mid ocean ridge system.' I have marked some of the movements with green arrows. I have paid particular attention to some of the movements you have scoffed at. 1) The ocean ridge between Australia and Antartica is pushing Australia towards Asia in general and indonesia in particular. This shows up as the dashed subduction zone between Australia and Indonesia. 2) The eastern end of the ridge system does indeed generate the Gulf of California and run into it, where mexican California is being separated from mainland North America. 3) A branch runs into the Red Sea, again separating Africa from Asia. 4) The separation of Australia and Antarctica is continud westwards so also separating Africa and Antarctica. This is pushing Africa northwards into Europe, closing the Mediteranean, not opening it. 5) These are current (today's) movements. Some of the plate movements are rotational or transform or both. 6) All the subduction zones are in the right place but some are not current, but historic, so some mountain chains are currently active volcanically, others have show past volcanicity.

Thanks for that information. It just shows what an enormous waste of of public money the UK is making in buying at least two new but hopelessly outdated fission reactiors from the French. We never should have abandoned ZETA.

Thanks, I really hope your got something out of this because I didn't mention particles once. Yes I did say effects. I am using general English words for your benefit. A quantum effect in a system occurs when some quantity (usually but not always some form of energy) can only occur in certain specific values and not in any other value, even nearby that are only say 0.001% different. These values are called (energy) states. This means that when the system changes energy it can only change by the differences between allowable energy states. Such quantities are said to be quantised for the system. Another quantised quantity is electric charge. None of the rest of your musings have any relevence to anything I said.

In another thread you said $100s on book.s I'm sorry to tell you that you wasted your money. Which book did you read that in ? [math]\frac{3}{4}is\;a\;proper\;fraction[/math] [math]\frac{4}{3}is\;an\;improper\;fraction[/math]

Sensei's notation does not conform to the nuclear reaction notation I was taught. For instance [math]{}_7^{14}N + {}_0^1n \to {}_6^{14}C + {}_1^1H[/math] Where the upper number refers to the mass number and the lower to the +ve charge number (so reckoned -ve for negative charges) I also agee about the short half lives, carbon-14 has short one in terms of billions of years at just over 5 and a half thousand years.

Thank you both again for your contributions. I agree there are interesting connections to computing. This was in part prompted by my family having a large jigsaw map of the world to work on at lockdown Christmas time. Another part of the family had a personalised jigsaw made from a closeup photograph of their family dogs on a grey sofa. Darth Vader black has nothing on fine hair/fur on a grey featureless sofa background. But in invoking the scientific method I was also considering human ingenuity as compared to something a monkey could do, given time. Since neither of you are english, you may not be familiar with the english expression "Brute force and ignorance" as some method 'any fool (or monkey) could employ'.

Thank's for the replies. The method appears to be try every combination until correct fit is achieved. Can brute force and ignorance be called 'scientific' ?

So can you apply the scientific method to jigsaws and if so, how ?

You ned to use somehing like Pilkington Optiview glass https://www.pilkington.com/en/global/products/product-categories/special-applications/pilkington-optiview-range/pilkington-optiview-protect

Mmm disappointing response to my question -- you might have learned something. I wasn't aware that Bolzano wrote any engineering textbook - This thread is supposedly about engineering texts.

The equation, as written, has zero net charge ( 0 + 0 = 0 ) on the left hand side but + 1 positive charge in the right hand side ( 0 + 1 = +1 )

Please check your second equation. The (electric) charges don't balance.

Are you ? But +1 anyway. I repeat my observation that this is just a wind up. isaac, I've rumbled your game. So [game] - on The game being [Insert your favourite reptile] - on My favourite reptile is [Komodo drag] - on or perhaps [Pyth] -on Your move I believe.

Sure, hope Ghideon's help works out for you. He (or Sensei) should be able to log into your router remotely from the internet. I used to do this all the time to mine. But keep sensitive information to private messages.
