At the end of last week in Ulyanovsk has started an interesting project Simple science. Its initiator is the teacher of UVAU HA Leonid Podymov.

— The main purpose of my lectures is to educate. I would like to tell Ulyanovsk on the latest and most interesting achievements in modern science into simple language so that it is clear even to the unprepared listener, — says the organizer of the “Simple science”.

Leonid physicist by education, so the project is focused mainly on natural Sciences. In particular, the first lecture was devoted to astronomy — or rather, cosmic distances and scale.

— Many people know that, for example, our Solar system is big. But it is actually an ordinary person is unlikely to adequately represent these scales and distances — simply because it is not something to compare. I tried using a few simple techniques to bring clarity in such comparisons, says the teacher.

So, during the speech he invited the audience to spend with him a few thought experiments.

— Let’s imagine that our planet has shrunk to the size of a standard basketball ball whose radius 12.2 centimeters. If we reduce all other razmery accordance with a given scale, we get the following illustrative figures: the Sun will be a ball with radius 13 meters. Continue reading

100 year spaceship

Humanity seems to have stayed in their home Solar system

In Houston there was a scientific conference on the most ambitious project of the century.

“Transition to transformation”

Humanity seems to have stayed in their home Solar system. Of his burning desire to go to other stars, scientists said at a scientific conference, held in October in Houston (Texas, USA). Experts discussed the most grandiose project of the century – “Centennial spaceship” (“100-Year Starship”, or 100YSS ).

– Despite all the technological advances of humans, in the field of space exploration we’re on the level of cave people, – assured the leader of 100YSS Mae Jamison. All we did was hang a station in earth orbit, where just sometimes come to live people. And also sent a robot to Mars, which only publishes Pictures in Instagram and writes in Twitter. The main task of space exploration in the long term should be the creation of colonies, which can live people. Continue reading

Long space flights

Russian scientists in collaboration with foreign partners have classified the threats to the health of astronauts during long expeditions, including during the flight to Mars, said “Interfax-AVN” on Monday, the Deputy Director of the Institute of biomedical problems Russian Academy of Sciences Valery Bogomolov.

“Three years ago, with our international partners, we determined the risk matrix and the degree of our knowledge about these risks, the degree of protection. This list is big enough, it about 15 positions,” said Vladimir Bogomolov, commenting on sending to the ISS first annual expedition consisting of Russian Mikhail Kornienko and American astronaut Scott Kelly.

The annual flight of the astronauts arranged, in particular, in order to prepare future long interplanetary flights.

According to the scientist, it is not only about physiological parameters, for example, about the influence of space flight on the cardiovascular system, the motor area or sensory abilities.

“Takes into account such factors as the adequacy of medical supplies on Board the spacecraft for the relief of disease,” – said V. Bogomolov.

He recalled that the flight, e.g. to Mars and back will take more than 500 days. Continue reading
