Photoreceptor cells
The human eye contains three types of photosensitive receptors called cones.
One type of cone is most sensitive to short-wavelength light (blue and violet), another to medium wavelengths (green and yellow), and a third to long wavelengths (orange and red).
Green lies in the zone where cones are most active, making it pleasing to the eye and easy to distinguish.
Physics of morning golden lights
Rayleigh scattering is a phenomenon in which short-wavelength light particles, such as blue and violet, scatter more intensely in all directions.
In comparison to short-wavelength light, long-wavelength particles like red and orange scatter less.
Therefore, during the evening or morning light, when the sun's rays pass through a thicker layer of the atmosphere, it can acquire a golden hue due to this uneven scattering.
What is it - antiHe?
Antihelium is like helium, only in reverse. Just like there is a proton and an antiproton. An antihelium atom is a particle with antiprotons and antineutrons. There are quite a lot of antiprotons in space, they are easy to generate, but antihelium is not easy to obtain. To do this, you need to collect 2 antiprotons and 2 antineutrons together and force them to form a particle :) at high cosmic speeds this is almost unrealistic.

Antihelium
Antigelium can be direct evidence of the existence of objects of macroscopic antimatter in the cosmos. And even in our galaxy. This summer, the AMS-02 experiment provided data on the detection of an antigelium particle as part of cosmic rays. It's a big sign for physicists to reconsider the baryonic asymmetry of the universe. But as is usually the case in physics, we need to wait a few more years and confirm this data. We need to get more antihelium events to be sure.
I'll go into more detail about all of this in my next post)

The mirror is a perfectly smooth and even surface.
Therefore, it doesn't absorb, but reflects light. Reflection doesn't come from the glass, but from the amalgam layer. It doesn't transmit rays through itself, but refracts them. The refracted beam exits through the glass back and enters the retina of the eye.

At one time I didn’t like yellow at all, and then I realized that it really suits me :)
In recent years, even physicists have begun to use machine learning. This saves time and resources.
