Grand Dukes

Posted by on

It seems to me Grozny was in the same period Demidov: Absolutely, yes. I'm sure there were times I even think on a conscious level with him, when he realized he had reached the top, and asked himself: is happy whether he actually reached if he happiness, while at the king of all of Russia? After all, he was actually the very first king. Prior to this were Grand Dukes. He was the first king of Russia. L.

Pavel: That is the pinnacle of all desires. Demidov: Yes, certainly. And is there footage talking about the fact that he seemed in question. Hoary already quite an old man I have a very interesting make-up: wrinkled face, a lot of wrinkles and even the scabs were, in fact it is known that he was ill. It is not known why he died. There is a version that he was poisoned, there's a version that he died from the disease, because they found mercury in his body.

It is believed that mercury could poison him. And in another version, in those days were treated with mercury. And there are shots where you can see by his eyes that he does not know what will happen, and does not know whether it was all that he did. L. Pavel: He lost his purpose in life, make sense? Demidov: I do not want to disassemble it because you want the audience to look yourself and do something about it thought. Do not feel like they are now directed to any particular party.

Earth Life

What is studying biology. You are beginning to study the basic biology (from the Greek words "bios" – the life and "logos" – the doctrine). Biology – the science of life, of living organisms that inhabit the Earth. Living organisms on our planet is very varied. That – and the people and animals, and plants, fungi and bacteria.

Scientists there are more than 3.5 million species of living organisms. They live on land, water, air. Scope of life is a special shell of the Earth – the biosphere (from the Greek words "bios" and "sphere" – a ball). The biosphere includes the lower atmosphere, water bodies, soil, the upper layer of the lithosphere. Biosphere area of distribution of life Biology studies the structure and vitality living organisms, their diversity, the laws of historical and individual development. All living organisms are closely related to each other and with the habitat. Living organisms affect the environment, and their existence depends on conditions of this environment. Section of Biology, who studies the relationship of organisms among themselves and with their environment is called ecology (from the Greek word oikos – a house, apartment, home – and "logos").

Vector Time

Posted by on

Let us recall the most basic concepts of speed, which teach in school, namely that speed – is a vector quantity. Those who remember that this vector is well known that the vector has a direction, moreover, the vector may not always be unidirectional. If time is inextricably linked with the speed that time – it's too vector quantity. And this is, in turn, suggests that it is tied to the direction of the velocity vector, that time can not be unidirectional, and this is quite easy to verify in practice. Take, for example, any movie. Until then, until we begin to view it, it does not speed, and hence the time it stopped. One may recall that a similar, we have already encountered when in the article "Speed" crossed the border the speed of light: no moving object in the form of material particles, so the movement of time is also absent. Including film, we turn and his time, and we can even adjust the speed of time.

And if we can turn in a movie clock? Without problems, but under one condition: we should have a movie player, remote control, so – and time. Without it, the movie with a given rate will move in one direction only. Does this example of an analogy with human life? Yes, the most direct. We move through life movie called "Destiny" in one direction and the one given velocity. Can a person change the speed and direction? Of course, can – this is the so-called time machine.

Flying Stunts and Aerobatics

Posted by on

Anyone who has ever been to an air show knows the mesmerizing effect aerobatics can have on an audience. It is always a thrill just to see a jet plane flying at enormously fast speeds, but to see such planes fly in tight formations, or in crazy patterns, or upside down, or straight down and then suddenly pull up at what seems like the last possible moment before crashing into the ground, makes for an exciting experience indeed.

There are five maneuvers which compose the foundation of aerobatic stunts. Those are horizontal and vertical lines; loops; rolls; spins; and hammerheads. Some of the types of tricks which can be done by combining these maneuvers are called the Cuban Eight; Half Cuban Eight; Reverse Half Cuban Eight; Chandelle;  the Stall Turn, or Hammerhead; Immelmann which is also called the ‘roll-off-the-top, or the split five.

One maneuver that is a real crowd pleaser is called Pugachev’s Cobra. In this stunt the airplane’s nose is suddenly pulled up. The plane then pitches up to about a 90-120 degree angle of attack. After that the nose falls back down to the horizontal, and the plane flies away in the direction it was first heading.
