Growth psychology – laughter isn’t acquired but innate
Growth psychology – laughter isn’t acquired but innate – British scientists have proved
that laughter is not something acquired, but innate. With the help of ultrasound was recorded
children in the uteri. The first facial movements have been observed in the second trimester,
and all elements detecting a laugh approx. 30 weeks. It was thus negated one of the existing
theory of psychological development.
Moonless development – Earth without Moon
Moonless development – Earth without Moon – Simulations 4 billion years of
development of the Earth without the presence of the Moon. Were performed in the
Research Center of NASA in Moffett Field, California by Jack Lisauer. In the developed model,
the maximum angle at which leaned to the axis of the Earth, turned out to be much smaller
than assumed earlier studies. The conclusions of the study were: Earth would be the Earth,
even without his extremely large satellite.
Stars turnover – Speed of stars rotation
Stars turnover – Speed of stars rotation – The Sun rotates at the equator at a speed of 2 km / s.
Astronomers have discovered that the star of the Tarantula Nebula – VFTS102,
rotates at a record speed of 600 km/s.
First birds – Victims of dinosaurs
First birds – Victims of dinosaurs – Paleontologist Jingmal O’Connor made in China discovery,
that the first birds were victims of representatives of the dinosaurs.
– “125 million years ago, dinosaur Microraptor Gui hunted and devoured entirely
representative of primitive birds from the group Enantiornithines.
The find confirms our belief that the dromerosaurs lived on the trees.“
Molecules from space – Primary gas created shortly after Big Bang
Molecules from space – Primary gas created shortly after Big Bang – Has been confirmed the
hypothesis about the origin of molecules from space. The researchers were able to discover
the so-called. Primary gas, which was created shortly after the Big Bang, it consists of hydrogen
and its heavier isotope deuterium. This finding confirms that in the Big Bang were created only the
lightest chemical elements, hydrogen and helium. Heavier elements appeared only after 100 Mln years.
Brussels tunnel – Experiment with photocatalysis
Brussels tunnel – Experiment with photocatalysis – In 09.2011. European experts began their
experiment in the Brussels tunnel, through which passes every day 25 thousand. cars.
100 meter length of building was covered with cement with titanium dioxide TiO2,
which is the source of a chemical process called photocatalysis, acts as a catalyst driven by
solar radiation (UV).
Cave lions – Cause of their extinction was narrow nutrition specialization
Cave lions – Cause of their extinction was narrow nutrition specialization – With accurate analysis
of the bones of extinct Cave lions that the cause of their extinction was narrow nutrition specialization.
Research collagen have shown that these animals mainly liked to the reindeer that consume lichens.
With the change in climate 19 thousand. years ago, this type of lichens disappeared from Europe,
which began dying reindeer. Cave lions also not able to adapt to new conditions,
and consequently became extinct.
Dinosaurs nest – Paleontological discovery in Mongolia
Dinosaurs nest – paleontological discovery in Mongolia – Paleontologists have discovered
in Mongolia population of 70 million years old dinosaur nest kind of Protoceratops Andrewsi.
It was in the 15 newly hatched young. This discovery proves that immature individuals
were in the nest after hatching and died not only as food for others.
But also because to external conditions.
Isaac Newton – English physicist and mathematician
Isaac Newton – Died 20.03.1727 (born in 1643), English physicist and mathematician.
Developed the law of universal gravity and other laws of mechanics. He formulated the
principle of conservation of momentum and angular momentum. He created the calculus
of variations. 10. 12. 1684 – His work “De Motu Corporum” about the concept of gravity
and its effect on the orbits of the planets, referring to Kepler’s laws, was read to the
Royal Society by Edmund Halley.
Christian Doppler – Austrian physicist and mathematician
Christian Doppler – Died 17.03.1853 (born in 1803), Austrian physicist and mathematician.
Discoverer of the phenomenon of the impact of approaching and receding source of sound waves,
or light on its frequency.
