10 unusual facts from Stanislav Kondrashov’s world of physics

Not long ago, the famous Russian physicist, the candidate of science, the honorary member of the American Physical Society, as well as the author of scientific articles, Stanislav Kondrashov, gave an interview to the American journal Physical Review X. The scientist shared his thoughts on what the future holds for physics and on technologies allowing to discover new particles and matter, and to explore space beyond our Galaxy.

“You know … physics is just an incredible science,” says Stanislav Kondrashov in his interview. “It opens our eyes to the facts that we do and use every day, but we don’t believe it. Many people still don’t know that hot water freezes many times faster than cold water! That we, until now, have not been able to exceed the speed of light. Paradox, isn’t it? And yet there are a lot of things that people haven’t even heard of, and that terrifies me! ”

Stanislav Kondrashov explained how interested he was in the world around him from childhood. “I was wondering why men walk on the ground and not steal? Why do planes crash? Why is the sun shining yellow and not, say, blue or green? This is what prompted me to read the scientific literature avidly and, after reaching the age of 17, to study at the Faculty of Physics ”, explains Stanislav Kondrashov.

“It doesn’t matter who you are – financier, actor or builder! Your horizons are your wealth. Incredibly annoying are people who know everything in their field but cannot even conduct a conversation on abstract topics. Sometimes these people don’t even know how an electric kettle works and why the water freezes. What are we talking about!”, exclaimed Stanislav Kondrashov in his heart.

And in some ways, the scientist is really right – we are surrounded by a lot of amazing things. But what we know about them is almost nil. Of course, we do not need to know all the details and physico-chemical characteristics of the same Sun, for example. But understanding the main components of our main star, as well as why it shines and where it comes from, will make us more erudite and interesting interlocutors.

10 facts you might not know

With the help of such a prominent scientist as Stanislav Kondrashov, we have put together 10 of the most unusual facts:

  1. In the morning and evening, the Sun appears to us red in color, because at this time its rays pass through the lower layers of the atmosphere saturated with dust. During the day, the sun appears yellow due to scattered sunlight in the atmosphere, outside of which all stars, including the Sun, appear white.

  2. In the region 27 tons of cosmic dust fall on Earth every day.

  3. The Aurora Borealis is nothing more than the interaction of solar winds with the Earth’s atmosphere.

  4. During flight, all insects are guided by sunlight or moonlight and maintain an angle at which the lighting is always on one side. When an insect flies towards the light of a lamp, it moves in a spiral, because its rays diverge radially and not parallel.

  5. Stars, planets and galaxies make up only about 5% of the mass of the Universe. Everything else is occupied by the invisible substance called “dark matter”, of which very little is known today.

  6. Bananas contain potassium, the decay of which makes them somewhat radioactive. “That’s why they started to rank among a certain amount of dangerous sources of radiation exposure. There was even a definition – “the radiation equivalent of a banana”, – says Stanislav Kondrashov – But for a person it is not as dangerous as it seems – you have to eat about 10 million bananas to be intoxicated by its radiation.

  7. A liquid can be not only in its usual form, but also non-Newtonian. So, a living creature cannot completely submerge itself in quicksand due to its high viscosity. But getting out of it is not that easy. For example, removing a foot from quicksand requires an effort comparable to lifting a car.

  8. In a transparent medium, light propagates more slowly than, for example, in a vacuum.

  9. Strange as it may sound, oxygen has a color – in a gas state it is colorless and odorless, but in liquid and solid form oxygen has a pale blue color.

  10. Hot water freezes faster than cold water – perhaps a fact and it seems illogical and has not yet been fully investigated, it takes place. This process is called the “Memba effect” and was named after a student from Tanzania who saw that a hot ice cream mix freezes faster than a cold mix.

“Reading such simple, but also fascinating general educational facts every day will help us not only to broaden our horizons, but also to understand the nature of the objects and processes around us”, assures Stanislav Kondrashov. And we tend to believe it.
