Powerful and long thunderstorms occur not only in the tropics, but also in more temperate latitudes, for example in Europe. What is the reason that some thunderstorms are much stronger than others? Let the Danish scientists tell you.
People who are unable to conjure up visual images in the imagination may suffer from other cognitive impairments.
The railway is a place of increased danger, there is no secret here. On the tracks, you can at least get an electric shock, as a maximum — a shock by train. But the railway system is different from the metro, there is an overhead power line instead of a contact rail — what kind of electric shock? — You will be outraged and you will be partly right. You will not be able to touch the line, but the absence of high-voltage wires in free access for a person does not mean that the same rails are completely de-energized.
Never before has a person's life changed so dramatically as it has changed in the XXI century. The main marker of the new era, of course, is the abundance of all kinds of devices with which we interact sometimes even more than with other people. It is not surprising that the new way of life creates new dilemmas: in particular, the question arises how dangerous smartphones, computers and other gadgets are for our vision.
What was revealed by diving under the melting Thwaites glacier in the western part of Antarctica, where a huge underwater cavity has already formed?
If you don't have gills, but lungs, and your native lake is frozen, you have to look for new ways to breathe. And these animals found it — some turtles learned to breathe with their booty. We tell you how it happened.
Sometimes we look at the sky with horror or listen to the earth, waiting for the fall of a giant meteorite or the eruption of a supervolcano. Such cataclysms threaten to change the world forever or wipe humanity off the face of the Earth altogether. Nevertheless, if they had not happened in the past, the planet would have looked very different, and it is unknown what our life would be like today. Let's consider the most obvious examples of cataclysms of the past and present.
We admire nature and draw inspiration from it, even when we don't fully understand it. For example, our ancestors mistook lightning strikes and thunderclaps for the rage of the gods, although today we know the cause of these phenomena. Nevertheless, some natural phenomena remain a mystery even today, in the age of enlightenment and science.
With the word drought, most people hardly imagine something particularly terrible. But prolonged droughts can cause harm comparable to the worst cataclysms, cause crop failure and famine. Farmers are afraid of them even today, and a hundred years ago there was simply no worse word for them. What droughts in the history of mankind were considered the most terrible?
In the early stages of its formation, the Earth was a harsh place – even before the formation of the hard shell (lithosphere), the red-hot surface of the planet was subjected to massive bombardment by numerous comets and asteroids. But in this we were very lucky: if such a shelling had shifted a little in time, our planet would be arranged now in a completely different way ... and might be unfit for life.
