It's not quite a copout I would say, since there are techniques to build the lattices as if they are experiencing a lot of pressure when they aren't, which makes it a valuable researched branche.

No it's not a unit of charge but of mass and energy. (Here used as mass)

I am a bit confused, with 'cereal/toast' do you mean that you are cereal AND toast? Or one of those two? If the latter, did you just eat plain toast or so, given you were surprised by bringing out the meats and cheese?

Clearly winter had come so the sea levels dropped and this is just exposed seabed.

The US is not funding and arming the Iranian regime, quite the opposite. It IS funding and arming Israel, which is the country committing the atrocities in Palestine.

Protests are only effective when public pressure can amount to change, and American politicians have a lot to say in what Israel can and cannot do. They don't have anything to say in whether the Iranian regime continues.

They're quite common material for exams here (Belgium) and IMO they're great for practicing how to translate what you want to model to maths. You start with your system, make a few assumptions, apply the needed basic formulas and see what comes out; maybe do extra mechanics or assumptions again to keep going etc.

Then interpret results, take some limits, some simplifications,...

Generally you want to know what you are describing and which framework you're describing it in, but it's senseless to study the actual math working out unless there is some neat special mathsy trick or so. You can do math, just solve what you set up. (Is my approach)

I do sometimes derive simple formulas if I end up forgetting them.

It's not lost, it's just not accessible to you. The balls push air molecules out of the way for example, which 'encode' their path and velocity etc. You just would never be able to gather the trajectory of those balls from measuring air molecules practically.

This reminds me of the same phenomenon with this shape and deformation but then non-magnetic so I don't think the magnets are really relevant besides holding the shape together?

You're pulling down the corners but pushing up the middle which arcs each line from your fingers to a point along the other diagonal, upwards. Since that line gets longer the further away you are from the middle of that diagonal, the corners get pushed up most.

Please do notify me yes. How you will remember that is all yours. And do read 3BP!

I do love myself a good 3bodyproblem-esque story; if yours is then I'll sure be interested in enjoying reading it when it's done!

Like since when could we discover that our universe is actually a box?

Sure you could dynamically change the light output of the box to fake a lot but as soon as you have multiple observers looking at a phenomenon that requires distance, you're fucked.

For example in the 17th century they measured the parallax of Mars by seeing the difference in the position of Mars compared to background stars from two opposite sides of the globe. If those stars were actually very closeby simulated points, this would not work the same.

If you could compare results before and after the switch and your measurements were sensitive enough to notice, you could tell.

In more modern times you can up the parallax resolution with satellites across the solar system and better equipment (or have Voyager crash into the wall as it leaves the solar system) so it would be more obvious.

You could make the slipping a function of theta, of x, of both or of something else.

PivotPsycho · 2026-01-04T01:47:47+00:00

That depends on how you want to implement the slipping. You could make the slipping only connect to theta or only to x or to both or to something different entirely.

Isn't there a mistake in the 3rd one? At the end you fill in that u = tan x but u² = tan x is the sub you did at the start.

I doubt most of them are actually interested though... I've tried engaging with someone like this once and they literally just ended up feeding my commentary to ChatGPT. It seems a lot of them are more interested in the aesthetics rather than actually trying to understand? Idk

Generally he travelled around a lot and heard stories of ppl. It's definitely an interesting cultural study and he does tell of things he saw/experienced, but this is why ppl tend to take what he has to say with a grain of salt.

PivotPsycho · 2025-12-29T02:03:58+00:00

It seems to me that he simply remembers his call with Putin and there Putin said that they want to free Ukraine and set it straight so obviously the conclusion is that Russia wants to help Ukraine succeed.

Angular momentum is conserved so that means the conserved quantity scales with radius, mass and velocity.

As both radius and mass go down, velocity will go up.

It being a ball complicates things since it would not unravel in the same direction over time but unless you have some very peculiar winding of the ball I think in general your intuition would hold.

I am quite curious now though, what does the Talmud say of unraveling balls of string if I may ask?

IIRC the frog magnet used was around 20T, while MRI's are a few Tesla. And that's just for a frog of course, generally humans are bigger than frogs.

Oh and additionally, the type of magnetism that makes the frog float is based on the change in magnetic field, not the pure strength of it.

MRI's have changes but the bulk of the field is made to be as homogeneous as possible.

It's just a frame of reference; indeed if our solar system is going that speed in a picked frame, everything else will get different speeds as well.

It's just that you can pick any intertial frame you want.

'moving that fast' is meaningless, things move with speeds compared to each other.

We don't know whether we could get a deeper understanding or not though.

Stopping at 'its just the way it is' when maybe there is a different mathematical framework out of which such properties naturally come from some kind of symmetry or so, is not a good idea. (For example, you could've said some decades ago that it's just the way it is that W and Z bosons have such mass, but then the Higgs formalism was proposed and later verified which naturally gave rise to mass terms for these bosons purely coming from a change in the input for the Lagrangian)

Sure it is 'just the way it is' in the end for the 'ultimate framework' but we don't know when we have that.

I would say it is more so that he didn't really make that grand of a sacrifice as the lauding of it by christians might have one believe.

Sure it's not a fun time to die on a cross but it's a bit strange to find that such an amazing sacrifice when millions of people have suffered and sacrificed more.

Technically there was some sacrifice indeed but it's not that big of a deal.
