What do you know about narcissism?š
Sometimes I like photos I take so much that I set them as a wallpaper to admire my work :)
I have said many times that for me it is art

ISS New Yearšš
I told you about the number of sunsets on the ISS. So, they celebrate the New Year 16 times as well:)
Although it is not a full-fledged celebration with fireworks, the crew can decorate the station with small garlands, souvenirs, or even an artificial Christmas tree, which is compact and lightweight to save space and minimize launch weight.
The astronauts gather together for a festive meal, and sometimes special dishes delivered from Earth are prepared for the occasion. For example, in the Russian segment of the ISS, there might be traditional dishes like Olivier salad(Russian salad) or canned stew.
They usually celebrate the holiday according to UTC time.
During the holidays, the crew is given a bit more free time, although critical tasks, such as station management and monitoring its systems, continue uninterrupted.

Could life exist beyond the Solar System?
I had a podcast yesterday and we talked about physics ofc and also about life...
In the Universe, according to the latest estimates, there are between 100 and 200 billion galaxies. At such a scale, it would be strange if Earth were the only place where life exists.
But the problem life elsewhere, we cannot verify it.
Why?
The answer lies in the laws of physics, specifically in the Special Theory of Relativity (STR). No information can travel faster than the speed of light (about 300,000 km/s). Even the stars closest to us are located at distances measured in light-years.
The light from the closest star to us, Proxima Centauri, takes 4.2 years to reach Earth.
The planet Proxima b, orbiting Proxima Centauri, is the closest potentially habitable exoplanet to Earth.
If life does exist somewhere out there, any signal from it must travel vast distances. But even if such a signal exists, we may simply fail to catch it, life at its source could vanish before the signal reaches Earth.
Thus, due to the limitations imposed by the speed of light, we live in "cosmic solitude": not because life doesn't exist, but because we cannot exchange information with it.
Sleep peacefully...if you dare...
So, youāre all comfy in your bed on Earth, while astronauts are up there suffering....
They canāt just lie down in a bed and sleep. Instead, they sleep in a special sleeping bag thatās strapped to the wall, ceiling, or floor (not that those concepts really exist in space). Total space lunatics... Honestly, Iād crap myself if someone just floated past me while I was trying to sleep.
And, obviously, you canāt just rest your head on a pillow either.
Oh, and letās not forgetāthey donāt see just one sunrise and sunset like we do. They see about 16 because the ISS orbits Earth every 1.5 hours. Every 45 minutes, they hit the boundary between light and dark, called the terminator (and yes, "the machines rose from the ashes...").
On Earth, the transition between light and dark shows up as sunrise and sunset, smoothed out by the atmosphere. In space, though, the boundary is super sharp.
Good luck sleeping with thatāthereās light shining in your face all the damn time.

Why I started to make such photos?
These are my first attempts at taking photos in underwear. Im 22 years old here. I didnt like my body then. I thought that I looked normal only in clothes. And I avoided any photos like that in every possible way.
I remember how embarrassed I was to show this to my friends.
I thought that they would look and decide that I was ugly. I was terribly embarrassed. But Im made in such a way that if it is hard for me, embarrassing and painful, I will still do what I want. I will try and feel these feelings. I wanted to see myself beautiful.
And not just see, but feel...
And you know, I think I succeeded.
I have a huge wealth here for myself first of all and Im very glad that you are also here with me. It's not about me specifically - what I am, but about the fact that the human body is beautiful. All the imperfections and peculiarities.
Some physics about headphones
From a physics point of view, sound is a mechanical wave that makes air particles vibrate and sends those vibrations to your ear.
Headphones, especially the ones you put inside your ears, concentrate sound energy on a very small area. Vibrations are created.
These vibrations pass through the fluid in the cochlea of your ear, where hair cells pick them up and turn them into signals for your brain.
If the sound is too loud, the wave has too much energy. This overloads the hair cells. With frequent or long exposure, they lose their elasticity. These cells donāt regenerate, so it causes permanent hearing loss.
The physics is simple: a wave thatās too powerful destroys sensitive structures because of the extra sound pressure and energy.
If you want to harm your ears less, use over-ear headphones. They create less pressure and reduce the load.
Itās like using a knife. It can cut anything because it presses on a small spot. But if you try something larger, itās harder to do.
Happy bc I got the histogram:) (Maybe it's still wrong ofcš)
Why exactly by 10 billion times?
(Continuation of the previous post about energy levels)
This is really non-trivial. Iāll try to explain it as simply as possible.
Each energy level covers different sources. First, the planet, then the star, and then the galaxy.
So, here it is.
The energy of the Earth is about 10Ā¹ā¶ watts, and the energy of the Sun is about 10Ā²ā¶ watts. You might wonder, "Where do these numbers come from?"
Well, this has been calculated by smart people long before me (you can double-check the calculation for a star if you're interested. Or I can show it next time). It takes into account mass, luminosity, and other factors.
So what do we do?
That's right, we divide one by the other.
And when we divide, we subtract the exponents (a rule of mathematics):
26-16=10
And is exactly 10 billion. :)
The exact same thing applies to the galactic level:
Here it's 10Ā³ā· (since a galaxy contains about 100 billion stars).
Exactly the same:
37-26=11
Well, it's slightly more than 10, of course, but it's approximately 10 :)
Kardashev Scale Levels for civilizations
The Kardashev Scale is like a rating system for civilizations, but instead of stars for a hotel, it's all about how well you can use energy. This idea was proposed in 1964 by Soviet astronomer Nikolai Kardashev. He believed that by knowing how much energy a civilization uses, we could understand how advanced it is.
1. Type I Civilization (Planetary)
These civilizations are like super-eco tech enthusiasts. They use all the energy their planet has: solar, wind, ocean, geothermal energyā¦ basically, they use everything they can.
Example: We are almost at this level, but right now, weāre more like a civilization still trying to crawl out of the cave and survive on coal. Weāre somewhere around level 0.73 on the extended scale: itās like almost leveling up, but not quite there yet.
2. Type II Civilization (Stellar)
Now things get magical. These civilizations can literally build their home around a star. They use all the energy of their star. To do this, they build things like Dyson spheres (think of a gigantic solar battery the size of a planetary system).
The energy at this level is orders of magnitude greater than Type I. Well, what else would you do if you want not just to collect energy, but transform your whole star system? You could totally think about colonizing planets and even traveling between them.
3. Type III Civilization (Galactic)
Imagine a civilization that controls an entire galaxy....They harness energy from billions of stars, black holes, and other cosmic sources.
These guys arenāt just living in the galaxy, they control its energy, and they could probably live forever. This civilization could become something like a superintelligence that understands and manages the whole universe
Whatās Next?
Some scientists have come up with even cooler levels for ultra-advanced civilizations. Who says the limit is just the galaxy?
4. Type IV Civilization (Universal)
These guys donāt just stick to one galaxy - they use all the energy in the entire Universe.
Heat, microwave radiation, gravitational waves - for them, these are just new energy sources. Who knows what kind of technologies they could have. The energy of the Universe is not the limit.
5. Type V Civilization (Multiversal)
Oh yeah, this is the ultimate level. These civilizations not only use the energy of their Universe, they can travel between universes in a hypothetical multiverse. Imagine, you could create your own universe and use its resources. Somewhere in these realms, thereās probably super tasty cosmic food and entertainment we canāt even dream of.
Crazy....
How Does It Work?
Each new level requires 10 billion times more energy than the previous one. If you want to reach Type III, youāll have to go through such a process that youāll need an ocean of energy
What catches cosmic rays?
AMS-02 experiment is installed on the ISS and is part of the CERN experiments. Why?
Good question. I don't know really haha:)
But the experiment control room is at the CERN base.
I had some photos somewhere... I'll find them and show you...
I was there, well, you can't go inside.
Otherwise, anyone will come, stick some shit in there and screw everything up. And America will be in shock...(It's USA's experiment mostly).
Well..ok!
AMS-02 works as a kind of sieve for the particles that pass through it. First, they get into a strong magnetic field, which bends their trajectory. This bend immediately gives scientists a hint about the charge and mass of the particle. There, using a school formula, you can figure it out:)
After that, the particle passes through several layers of different detectors. Each layer records its own: direction of movement, speed and energy of the particle. It's like a filter, where the particle leaves "traces" by which you can understand what exactly flew by - an ordinary proton or a rare antiproton, or something else.
The collected data allows us to study cosmic rays. Their composition and the composition of the stars from which these particles arrived. Or, more precisely, supernovae. Although there are now disputes about what are the sources of cosmic rays, haha:)
But if something rare occurs that goes "beyond the standard model" of the composition of cosmic rays - that's already interesting. Antihelium as example. It's almost impossible for it to form secondary in flux, so it must have come from somewhere, like antisupernovas or etc. we really don't know yet
But it's interesting....
I also added some pics from CERN and AMS-02 websites
The structure of AMS-02 sooo complicated, really. But you can see the magnet:)
Cosmic Rays: The Universe's Largest Collider
When we think of colliders, we immediately imagine installations like the Large Hadron Collider, where particles are accelerated to enormous speeds. Particles collide, creating conditions close to those that existed during the Big Bang. But did you know that we have a natural collider that has been operating in space for billions of years? These are cosmic rays.
The Large Hadron Collider accelerates protons to energies of about 6.5 teraelectronvolts (TeV). One TeV is about the energy of a flying mosquito, but the collider packs it into a single particle, which is smaller than an atom. This is a very high density. However, space has created its own "accelerator" with much more impressive capabilities.
Cosmic rays are particles accelerated to energies of the order of 10Ā²ā° electron volts (EV), which is almost 10 million times greater than the possible energies in our terrestrial colliders.
A very fast mosquito... damn it...
When these particles collide with molecules in the upper layers of the Earth's atmosphere, they create a cascade of new particles, similar to what happens in colliders(2d pic). Only here the energy of collisions can reach values that humanity is not yet able to reproduce artificially. By the way, I'm not even sure that this is possible on Earth. It would have to be a very large installation.
In fact, space offers us experiments of a scale and power that are impossible to recreate on Earth, turning cosmic rays into our natural "collider of the Universe". But catching them is not very easy. I'll tell you about this next time!

What if we put your fat ass in space?
If we talk about space, then before our eyes there are images where astronauts and objects seem to float in the air.
But what happens to mass in space?
On Earth, we feel our weight (mass) due to gravity, which pulls us to the center of the planet. According to the formula
mass * acceleration of gravityā mass*10
(yes, on the scales your fat ass is weight, not mass).
In zero gravity, objects don't press on anything and nothing presses on them.
But this doesn't mean that mass disappears. That is, pushing your fat ass is still necessary, it's just that now you can't lean on anything. The difference is that we dont feel gravity, but only see how everything around us "floats". Even your ass will float, yes.
more simple:
you still have to push a mass ~5kg if you have weight 50 kg on the Earth. You should give it acceleration, etc., although it is not so difficult. There is no need to "fight" with the attraction to the Earth.
Watching information about grants I sent to myself in telegramš¤”(no code haha)
post of angeršŗ
I would like to be a little angry, actually. I post pieces of my code on threads. In photos. I show my progress. + I also always accompany it with my photo. Because I like it that way. I think it dilutes the boring code and the author is visible. At first, I was accused of my breasts and body. That, supposedly, why would I post code and my boobs, ass, etc.? Why? I always wanted to answer suck my d*ck(clitoris).
NOW. The situation is completely the oppositeš¤”š¤”
Im accused, not for the first time, that the code is allegedly not mine. Seriously? Do you think that someone from CERN or somewhere there is so stupid that they would write such an amateurish code? I write this nonsense myself :)
I have particle physics education, yes. But I didn't study everything fully, I had courses but it's not enough for good work with it.
This is evident from the mistakes and the style of my comments. And from the way I explain the histograms and other things.
I don't know what's going on in the heads of people who are looking for some kind of catch in the fact that a beautiful girl can also program. Or learn to do so. Stereotypes are very bad.
Think... brothers...
your poor student is so busy lately that she doesn't even have the strength to post(
