Aurora๐
No matter how strange it may sound, but it is the Sun that is the main "culprit" of the aurora.
High-speed solar wind particles collide with atoms in the Earth's upper atmosphere. The effect is observed at high latitudes.
And the color depends on which particle and at what h...
ะฐ Prism)
Do you remember that white in physics is the sum of all colors? And black is the complete absence of color. A prism, due to its structure, refracts a white beam inside itself and gives a color spectrum at the output.

I am very depressed after finishing my master's degree.
I broke the usual pattern that on September 1st I have to go to study for the 18th year.
And I'm sitting in some kind of emotional hole, I don't understand what to do and how, until I go to PhD.

Forse of friction
The force of friction is the simplest school topic known to everyone. Everything seems to be clear, nothing so unusual. But it's actually a very interesting and important thing.
If it weren't for friction, you wouldn't be able to walk, sit, wear clothes, hold hands w...

Oh my goodness, as long I waited such background. Just white walls behind me, nothing more

There is such a concept in cosmology - the observable Universe.
It is the part of the Universe we are theoretically able to study, see, feel, touch and all that๐
But also along with this concept there is one more thing - the metagalaxy
This is tha...

The rings of the planets are dust, gas and icings rotating at high speed.
All gas planets of the solar system have rings (Jupiter, Saturn, Uranus, Neptune). It is also supposed that the Earth also had rings, but not for long.
The most common hypothesis for the formation o...

Nebula
What is a nebula?
This is the remnant of matter after the death of a star - a supernova explosion. Part of the particles is carried away at great speed from the place of the explosion, while the rest remains. And yes, nebulae are not colored. It's just an image that w...

Physics of sunset ๐
I watched such a beautiful sunset in Moscow yesterday. Every time I admire like a child.
True, from the point of view of physics, this beautiful phenomenon sounds quite simple and unattractive)
Sunset is a refracted visible light from the Sun in a certain way. At dif...

What if I'm lying to you? Maybe I'm not a physicist at all?)
Physics for tonight?)
The light from the stars that you see in the starry sky has only now reached the Earth. Most likely all these stars have long been dead. This happens because the light from these stars travels a huge distance + the Universe is expanding all the time.
And it tur...
