If we assume that Santa Claus is a folkloric element, symbolizing not a generalized, collective image of some kind, benevolent uncle who comes once a year, but rather a natural phenomenon inherent in our world de facto – let's say, like the change of day and night – then it would be permissible to consider his actions in the same way as an ordinary energy process. In this case, the synthesis of gifts for 91.8 million children, given the input data in the form of a Lego construction set (about 1 kg), can be analyzed.
Let's consider the process of obtaining matter from energy.
Data for analysis: the famous E=mc2. The time allotted for synthesis is also known – 31 hours, i.e., 31*60*60=111600 seconds.
So, 91800000*1000*111600=10244880000000000. This is the energy in Joules required for the synthesis of the specified amount of matter. Considering that the Sun emits 6279527953568350 Joules to the Earth in the same amount of time, it turns out that the annual energy deficit is 3965352046431650 Joules. Considering that the Christmas tradition has been around for about 2000 years, we can confidently say that we would have frozen a long time ago...

KostyaN, I didn't immediately understand the meaning. :) But I liked it: it's like a haiku!
On the contrary, we should be glad that he is silent: we had some fun – and that's enough!
Let's move away from the arguing and talk about something pleasant. After the recent appearance of Slonysh in the thread, I remembered: we have girls reading this, so let's express ourselves more culturally and restrainedly!;)
By the way, speaking of girls. I once came across an article that I liked, and I want to share it with you. But first, guess: who is this beauty in the pictures - a photo model, a mannequin, an actress, a singer, a TV presenter?
Whoever knows, don't give it away!;) (I think some of you definitely know, because you are interested in the same field in which she has excelled).

New Year's was here, I didn't have time.
I'll reply soon, don't worry.

Spare our sinful souls!

I'm not the one claiming that a bubble cannot form – it's modern, generally accepted physics that makes this claim.

the message doesn't fit :)
I wrote 20 pages in Word
so, I guess I don't need to write it

There is no contradiction, Ariputra. The pressure inside the bubble is only slightly higher than atmospheric pressure, just enough to overcome the atmospheric pressure itself, the pressure of the liquid column, the surface tension, and a little more so that the bubble can expand. That's all (and if you still insist that the pressure inside the bubble is 10^8 Pascals, then take a pot of boiling water. Bubbles form at the bottom, the very same ones, with the very same pressure. Let's say their total area, which they occupy at the bottom, is about one decimeter square. That is, the force acting on the bottom is 10^6 N, which is the same as placing 100 tons in the pot. Why doesn't the bottom of the pot fly out from such a force?). Any schoolchild knows this, and doctors certainly couldn't say that this is not explained. What modern physics has not really explained are some elements of macrophysics (more precisely, there are hypotheses, but not all of them can be experimentally verified at the moment, for example, wormholes), and also the transition from quantum physics to macrophysics is not entirely clear in some places.

The forum's technical capabilities couldn't accommodate your thought.
