Quantum gravity and gauge neural network
Non-linearity is expected in anything related to gravity off the low-field approximation, ever since 1915. Much more unexpected is "counterdicing of time." Before trying to get a full grasp of it, what about a rough grasp of it first? So let's start with a simple question: What is "counterdicing of time"?

I can't make heads or tails of any of this.

Carrots in the Freezer
Quick freezing/slow defrosting... Keys to yummier food. As I understand, it's a question of texture. I wonder how significant all this is nutritionally. I've read that, after a while, pretty much every macromolecule that you take in is broken down into monomers. The gastric juices are mostly hydrogen chloride, very acidic. Somehow, your metabolic system is not "interested" in having carrot cellular tissue, but the amino acids it's made of, and such.

Very interesting. Thanks a lot, @StringJunky.

Carrots in the Freezer
Thanks a lot for the answers, @studiot and @iNow. Thanks also to you, @dimreepr. I would like to know whether it's in the proteins or the polisaccharides, though. As well as loss in nutritional value. I should think it doesn't make that much of a difference nutritionally though, as pretty much everything "poli-" (protein or otherwise) hydrolyses in the gastric juices, and is broken into monomers.

All of them? Blanch them first not matter which? Potatoes, carrots, cabbage...

Does the expansion of space mean anything for the movement of matter in space?
Easy come, easy go.

I agree too. @Prof Reza Sanaye has an interesting way of saying things that are absolutely spot-on, and then trying to clarify by sending what to me looks like impenetrable clouds of philosophical fog.

Carrots in the Freezer
I've observed that carrots don't keep well in the freezer if you just put them there. They deteriorate considerably in texture, suggesting to me that some denaturation is going on. After googling for it, I've found that it's recommended that you "blanch" them first, which amounts to washing them, removing differently coloured spots, cutting them in dices or slices, and boiling them shortly. Does anybody know the molecular basis for this? Can any general rules be applied for vegetables depending on the content in starch, carotenoids, etc.?

Possible Nobel Prizewinning Discovery
It was a long way away from Sidney, last time I took a look at the maps, @beecee. Continental drift is not nearly as quick as it takes.

Hiatus
As a Mahayana Buddhist would say: Great faith, great doubt, great determination. May you find your Buddha nature, my dear friend, whether be it Theravada or Mahayana way, or any other honest and sincere way, it's a worth pursuit. Best luck.

Can I say that Time is Linear?
Where do these words come from? Sorry, I'm lost.

Einstein's Simplicity
This is the more trustworthy version, I think: https://www.goodreads.com/quotes/271951-you-do-not-really-understand-something-unless-you-can-explain My grandma --my father's mum-- always beat me at chess --before I learnt some strategy with my brother, but by then she'd already passed away--, so I guess I'm not fully qualified to qualify anything here. If that's what Einstein really said, and he was right, maybe it just means we cannot ultimately understand anything.

Why are professors such assholes?
Professors are neither less nice nor more than the average person, in my experience. They're far busier than the average person though. Paperwork, teaching, exams, research, other academic duties... Work tends to spill over out of hours. Two days without getting an answer is not enough to judge a person as "an asshole" IMHO.

Can I say that Time is Linear?
My problem with this question is "linear in what?" "Linear" implies a relationship between two variables...

Heisenberg's uncertainty principle for dummies?
You're absolutely right, @MigL. It was @studiot's fellow Englishman, P.A.M.D. Those are equivalent, and the HUP can be proven by Dirac's formalism too. https://en.wikipedia.org/wiki/Transformation_theory_(quantum_mechanics)
-
Heisenberg's uncertainty principle for dummies?
The eyes of the beholder can be a chunk of iron at room temperature. Any system that interacts with the quantum system under observation and makes it decohere in the particular variables under consideration. Beholding is not that special. I basically agree with everything else that's been said about the difference between HUP and the observer effect.

I'd heard about ESPN, though. I'm not a complete ignorant. 🤣

The Spirit Of Science Forums
Take comfort in this: If Euclid himself were to come back to life and tried to give some of his views on modern theories on these forums, without thinking with any care what science has been up to for the last \( 2.2 \times 10^3\) years, his ideas would be probably dismissed just as quickly as yours have. And rightly so.

The Spirit Of Science
Dear @PrimalMinister, I'll tell you of the cautionary tale of Enrico Fermi. In the mid 1930s he submitted a paper to Nature. It was flatly rejected. Today we know it contains the essence of beta decay at first order. Of course, it miserably fails at every other order you may wish to push the theory through. Today we know why: Essentially because he missed the need for massive Z's and W's in weak interactions. He didn't get discouraged though. He pushed forward because he thought he had had a good idea. And he managed to get it published somewhere else.* Mind you, 1) He didn't try to explain everything 2) He wasn't discouraged 3) He didn't spend a moment of his valuable time in criticising Nature's editors and referees --to the best of my knowledge Why aren't you a bit more like Fermi? * E Fermi, Attempt at a Theory of \( \beta \)-rays, Il Nuovo Cimento, Vol.11, p.1, 1934; Zeitschrift fur Physik, Vol.88, p.161, 1934. (My red emphasis.)

How many quarks in a proton?
It's two up and one down. https://en.wikipedia.org/wiki/Proton Plus gluons dancing around telling the quarks and each other to change colour, plus a number of virtual quark-antiquark and gluon states. That soup is what Lisa Randall refers to as "the sea".

Do you understand the articles on arXiv?
Those are scientific communications that serve many different purposes. You have pre-prints (highly technical papers that are sent for consideration before they've gone through the peer-review system), lectures notes (of different degree of pedagogical approach), letters, books... There are filters (not everybody can "publish" there). And whether you can read it like most people read the newspaper highly depends on your level of knowledge as well as on what particular paper you read).
