)) Mort, the Wolf, is basically hinting that you can use this prosthetic to play on a computer and navigate Heroes of Might and Magic. To do this, you need to give it a command to control the computer mouse (press buttons with the prosthetic).
Is that clear?

My face literally hurts from all the facepalming.

To do this, you need to give him a command to control the computer mouse (press buttons with the prosthesis).

That's just nonsense.

I understand that there are several modes, but to have a special mode for controlling the mouse is just absurd.

But you were clearly told in English that there is such a mode.
And what, people who install such a prosthetic don't need to use a computer?

What is the point of these modes? They are unnecessary; we need to improve the character creation system.

Make it.

I don’t work there, so what am I supposed to do?

Then don’t do it.

Menty, you promised to update the topic!

Okay, I'll update it.

Scientists have created a nanomaterial 10,000 times thinner than a sheet of paper and placed 10 million transistors on it.

I initially thought of graphene; there are certain similarities, although it's not quite the same. I'll write about one of the most interesting experiments of recent times, namely the Higgs boson. First, the theory. The vast majority of sources say that the Higgs field is responsible for mass, and so on, like a billiard table covered in glue. As far as I know, this is only weakly correlated with reality. I'll quote a source that I liked from this point of view:

HIGGS FIELD -- in quantum field theory, a hypothetical scalar field that interacts with gauge fields without violating the gauge symmetry of the field equations: proposed by P. Higgs (UK) in 1964. It is assumed that in the main (lowest) energy state, which corresponds to the physical vacuum, the average value of the Higgs field is different from zero, which leads to spontaneous breaking of the gauge symmetry of the physical states of the described system (see SPONTANEOUS SYMMETRY BREAKING). In this case, particles corresponding to gauge fields can acquire mass. Interaction with the vacuum Higgs field can also serve as a mechanism for the emergence of mass for leptons and quarks.

The part in bold is very important. By particles corresponding to gauge fields*, we mean bosons. One of them, which corresponds to the electromagnetic field, is well known from school -- it is the photon. This particle has no mass and moves at a constant speed. However, the other bosons, namely gluons, as well as Z0, W+ and W- bosons, have mass and cannot move at the speed of light. The situation is especially interesting with the last three bosons, it is not easy to explain where their mass comes from without introducing the Higgs boson. Even worse, one of them (I don't remember the details now, I can't find them on the Internet) interacts differently with different electron spins, and another does not interact with one electron spin at all. All this "magic" is explained by introducing a new gauge field -- the Higgs field, and the boson that corresponds to this field. It was assumed that our world is asymmetric with respect to this field, which led to the indicated properties of bosons. Don't even ask how, I didn't understand, you need to study the subject specifically and read books. Although you can draw an analogy: if we lived, for example, in a constant magnetic field, then we would constantly be surprised why moving electrons tend to curl up in a certain radius. In my understanding, something similar exists here, although at the same time it is something completely different. By the way, this is briefly written here (first paragraph): http://www.sciencemag.org/content/338/6114/1569.full Now about the experiment itself. In general, you can read about it in the same link. For the lazy, I will clarify that the circumference of the LHC (Large Hadron Collider) is 27 km. Particles in it rotate simultaneously clockwise and counterclockwise in the form of beams, and protons were chosen as particles. The Higgs boson can be produced in at least four ways: The description can be found here: http://elementy.ru/LHC/LHC/tasks/higgs/production_decay As far as I understand, all these processes were tested in the LHC in one way or another. With a certain probability, they all occur during the collision of protons, and then it's just a matter of properly tuning the detector to detect one or another reaction. When the experiment was just beginning, the main question was whether the protons had enough energy to produce the Higgs boson, because people had only a rough idea of its mass. The collision energy of particles in the center-of-mass system at the LHC was 7 TeV, and then it was increased to eight, which ensured the ability to detect a particle with a mass of up to 1 TeV -- a clearly good result! The heaviest discovered particle (the top quark) with a mass of 173 GeV is easily detected on this device, as are all other particles. As a result, the mass of the Higgs after measurements was found to be around 125 GeV. Not a little, but the capabilities of the LHC were more than sufficient. In the previous link, you can also see graphs corresponding to the decay of the Higgs boson. They are important, because what to do with the Higgs boson itself after its birth is completely unclear. The algorithm is to wait for it to decay (and it will take a very, very short time, namely 3·10^(–21) seconds) into two other particles, you will probably have to wait a little for them too, and then we will already fix some electrons or photons (photons can be direct products of the decay of the Higgs boson, from this point of view they are especially convenient). This is how (schematically) the decay of the Higgs boson into a pair of Z bosons looks like: The Z boson, in turn, will decay into a pair of electrons (green lines in the figure), and the second such boson into muons (red lines). This scheme was studied in the CMS channel. In general, there are several channels at the LHC, including the one mentioned. Statistics on them were collected on this site: http://elementy.ru/LHC/LHC_results/higgs_study I recommend taking a look, there are several decay schemes of the Higgs boson, as well as statistical errors, there are several beautiful pictures related to this. By the way, some of the pictures are funny. Here is this one, for example: Here you can see that two points out of eleven, even taking into account the theoretical errors on them, do not want to correspond to the average value. But, as they say, if the point does not fall on the curve, then it's worse for the point. I hope this modest material is useful here ;)

Dude, why are you making things so complicated?

Just write that the Higgs boson exists, and that's it.

Well, everyone already knows that, but maybe some new information will appear here.

It turned out to be very funny.

Add to favorites, I've always dreamed of an oscilloscope animation, and this exceeds all expectations, it's a real art form, very beautiful!
