I don't kneed at all these days.I just incorporate all the flour,let it rise and then turn it out into the tin to rise before putting it in oven. Not as good as from a good baker's but easy enough and perfect (normally) when fresh.

Buy one ,get the other half price https://www.bbc.com/news/world-us-canada-65047436

They are locking him up today They are throwing away the keys I wonder who it will be tomorrow You or me I wish.

Imagining a repeat performance of his glory days back in Russia under the golden shower?

It has taken me over 40 years to add garlic on top of onion.I am still working out if it is any good.

Must have been the Deep State.

There are some ingredients that are fairly disgusting but blend in ok like asa foetida (devil's dung) and fish sauce which they say can be used in meat dishes but I cannot bring myself to test. When I got fed doing the grape harvests I noticed it was common practice to finish (or begin) the soup by adding with a bit of wine in the bowl.

Combined tastes probably don't "add up" so the taste of that chemical may get altered by the other flavours in the sauce or food. I drink coffee with my hot milk in the morning and never notice how fresh the filtered coffee I use is.It can be up to 2 days old and I wouldn't notice the difference.

I have just come across the name of Karl Pearson and am interested because he is said to have been influential on Einstein. His book ,The Grammar of Science, seemingly written at the end of the 19th century is a window into intellectual thinking then ( I have barely begun it) https://www.google.ie/books/edition/The_Grammar_of_Science/k1c_AQAAIAAJ?hl=en&gbpv=1&printsec=frontcover I am extremely put off by his "devout racism" however(which I have not encountered so far in the book and may not feature) Is anyone familiar with him at all? I think he was pretty well considered as a scientist and ,so far has quite a bit of opinion regarding the value of teaching science and especially the scientific method which he thought should be inculcated throughout society although I suspect he may have been thinking of the "better classes". https://www.historyofdatascience.com/karl-pearson-creator-of-correlation/

Yes,thanks.I think that explanatory visualization was around at the time when the first gravitational waves were detected some years ago. @swansont explained you needed a "dumbbell" shape to produce the waves,I think and @joigus said that you only got g-wave emissions in extraordinary large systems comparable to the big bang although he did mention the gravitomagnetic phenomena that I think are yet to be detected experimentally. I have read a few comments elsewhere about the possibility of engineering micro black holes but it is just the odd comment I have seen and I think we may see cheap fusion power before they get around to marketing diy g-wave kits</sarc>

Sure it enters into the equation.I tend to agree that value judgments are learned and relate to the context. But some of the context can be an appreciation of the work involved in making a product and a respect for the lives lived making and developing it. Not everyone will share the final assessment but ,in @exchemist 'a example most did ,presumably because the product was close to what was aimed for and passed enough criteria for all or most (in his opinion) to agree that it had distinguishing features. Distinguishing features often equates to an increase in monetary value and if people have spare cash it is not unreasonable to expect they will use it. I have (my partner ,not I) 3 bottles of wine that have sat in a room in our house for the past 40 years and are now apparently worth around 1000 each at auction. I keep them flat and out of the light and have no idea or real interest if they would taste good or not. You can't taste them without ruining them unless you know what you are doing and so they just sit there as it is too much trouble to ferry them to an auction house in London. We had a wine grower who stayed with us some 15 years ago and he told us that if you have a bottle of "good" wine that has spoiled it is possible to recover the quality of the wine by using it in cooking. The lost flavour returns.No idea if it is true but he sounded like a professional.

@swansont please ignore this. I think I understand that point now(ie there is a gravitational effect but not necessarily or in any likelihood any gravitational waves)

Perhaps irrelevant but did Einstein state this or did he perhaps just state that they were indistinguishable with the qualification coming some time later? (I have heard that General Relativity has advanced a lot since his time ,even as his predictions still to this day keep getting shown to be correct as in gravity wave detection and hopefully gravitons one day)

Why is it called the equivalence principle if gravity and acceleration are not equivalent? Is there some other equivalence ,or some aspect of the relationship btw the two phenomena that is being referred to? Is it possibly the equivalence btw the acceleration caused by gravity and the inertia involved in accelerating mass?

That is true (apologies ) Is gravity a synonym for spacetime curvature? Suppose a system was accelerated at one point rather than uniformly ,would that create tidal forces? Suppose Einstein's sealed box was accelerated at the one point would that cause the box to break up in the same way as tidal forces would break it up or strain it?

So ,if there are very small accelerations in a system which do not produce gravitational waves do they have any gravitational effect at all ? I understand that in the frame of the accelerated objects acceleration is indistinguishable from gravity - but (as per @joigus) this is not a frame independent effect. So can I take it that there are no gravity related effects from any accelerated motion,specifically that there is no effect on the gravity field?

I did a couple of seasons of the vendanges many years ago . Maybe that is when I heard it said that the best wines tended to be sold abroad. Could that be why I found it easy to get Merlot wine over here or was it perhaps just a case of a lazy description? I only really drink wine when someone stays and leaves a half bottle behind and I cannot bring myself (or even conceive of) throwing it out. My partner doesn't drink it at all and just holds the same glass until the end of the evening or until she can spirit it away.

Does "Einstein's sealed room" cause gravitational waves if the acceleration is strong enough? I had thought all acceleration produced gravitational radiation but you said a while back in this thread this was not the case and a "change in the quadrupole moment was required" Could you explain a little further about that? (or would it be easyish for me to look that up on google?)

Thanks again.

The truth is such a slippery and faceted customer. Even your crooked psychopathic and fabulist ex pres knew to call his propaganda outfit "truth social".

Thanks.

Well spacetime curvature is just a model isn't it?Can't an accelerated frame of reference show spacetime as curved also? (Stop me if I am talking rubbish -I normally am)

Does acceleration cause spacetime curvature?(it seems to cause gravitational radiation and doesn't the equivalence theory say that scceleration is indistinguishable from gravity except for tidal forces?)
