Strongest acid – Fluoroantimonic acid
Strongest acid – Fluoroantimonic acid – Actually, it is a super acid that is a mixture of hydrofluoric acid (HF) and antimony pentafluoride (SbF5). It is a thousand trillion times stronger than concentrated sulfuric acid. Even short-term contact with the skin can result in serious injuries or death – just like inhaling its vapors. Fluoroantimonic acid is stored in special containers.
Our planet composition – What is inside the Earth?
Our planet composition – Crust, mantle and core. In this abbreviated way one could characterize three layers of Earth, which were created at the beginning of its existence.
- Lithosphere – Top layer of Earth, which is in direct interaction with other terrestrial spheres, such as the hydrosphere, atmosphere and biosphere.
- Crust – It consists of the oceanic and earth’s crust. The thickness of the earth’s reaches up to 70 kilometers. The oceanic is thinner and its thickness varies between five and ten kilometers.
- Conrad’s discontinuity – Horizontal surface of the discontinuity in the earth’s crust that forms the transition between the upper and lower layers. Its depth varies in different types of crust from 5 to 30 km.
- Mohorovićic’s discontinuity – A layer that geologically defines the passage of the earth’s crust and upper mantle. Occurs in 20-90 kilometers deep under continents, and 10-20 kilometers under the oceans.
- Earth’s mantle – Layer consisting of upper and lower mantle. The upper reaches the depth of 90 kilometers. The lower one is assigned a depth of 650 km to the Earth’s core, and therefore approximately 2,900 km.
- Repetti’s discontinuity – The area between the upper and the lower mantle.
- Gutenberg’s discontinuity – Part of the Earth’s envelope, which is assigned at depth of 2,900 kilometers. Below it is the core of the Earth.
- Core – Geosphere, located in the center of the Earth. It starts at depth of 2,900 kilometers below the surface and covers approximately 31% of the Earth’s mass, with iron and nickel being the largest part of it. The core is twice as heavy as the Earth’s mantle and consists of a semi-internal inner core, which, among other things, creates the Earth’s magnetic field.
Andre-Marie Ampere – Thoughtful and versatile scientist
Andre-Marie Ampere – (1775 – 1836) – The ancestor of electrodynamics did not go to primary school, his father taught him alone. Ampere sent his first scientific work to the Lyon Academy of Sciences (Academie de Lyon) at the age of 13! A quiet life and urgent studies were interrupted when his father was guillotined in 1793 for the Jacobin dictatorship. Eighteen-year-old Ampere has suffered this trauma. After the period of mourning, he returned to science and spiritual work. He was interested in mathematics and physics as well as in philosophy, botany, chemistry, as well as Latin, Italian and Greek.
Son Jean-Jacques Ampere (1800 – 1864) after his father’s death finished his work. Which was to classify the sciences –
Sketches from the philosophy of science, or an analytic representation of the general classification of all human knowledge
But his greatest merit is description of magnetism and subsequent establishment of the theory of electromagnetic phenomena as the basis of electrodynamics. He also created the first magnetic coil, which became the basis for the later telegraph.
At the age of 22, he began to teach mathematics in Lyon and later became a professor of chemistry and physics. For nineteen years he taught at the Polytechnique in Paris. During his lifetime he belonged to many scientific societies and he was also appreciated abroad. Unfortunately, his financial situation did not reflect merit. He often lacked money for experiments, which delayed his work.
He spent most of his life traveling, while on one of them in Marseilles, on June 10, 1836, he died. On the gravestone, according to his wishes, engraved: Tandem felix – Finally happy.
Oldest pictogram – Presentation of concept
Oldest pictogram – Presentation of concept with image – Archaeologists in Gobekli Tepe
in Turkey have found the oldest pictogram, the representation of the concept with the image.
On one of the obelisks they discovered the drawing of a human head in the wing of the vulture
and the headless human body under the stele. Around the body are birds and scorpions.
According to experts, this is a pictorial representation of a particular event. The drawing comes
from 12 thousands years.
Probably the scene is related to funeral rituals. At that time, people buried dead in open graves,
where they left them to devour predators and scavengers.
The locals believed that the soul of the deceased would then go to heaven. Imagery about
the funeral habits of the then Gobekli Tepe inhabitants, archaeologists gain first of all from
the findings of the oldest temple complex that served as a religious center for a larger region.
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.“
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).
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.
Albert Einstein – In 14. 03. 1879. Was born German – Jewish physicist Albert Einstein,
creator the theory of relativity, which apparently seems to be devoid of applications.
However, it is a device which, without this theory would not work – a GPS receiver.
In 1921. He won the Nobel Prize for his explanation of the photoelectric effect and
contribution to the development of theoretical physics. From the age of four he played
the violin. Elsa, his wife recalled:
“As a little girl I fell in love Albert, because so beautifully played Mozart on the violin. […] “
