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.

CME – Coronal mass ejection – Eruptions on the Sun

CME – Coronal mass ejection – Every second the Sun emits around two million tons of particulate matter – or at least that’s usually the case. In the atmosphere, however, sometimes there are enormous eruptions from the corona (Coronal Mass Eruptions, CME). These types of hurricanes are among the most spectacular phenomena in our part universe . In the process, the Sun loses much more weight than usual. The speed of winds reaches even 10 million / h. CME is a cloud of gas built of electrically charged particles (physicists call it plasma gas). Plasma hurricanes can reach Earth and call the so-called geomagnetic storms that affect electronic devices, causing short circuits and equipment damage.

It is impossible to predict how dangerous it can be for satellites. The Internet and computer-controlled objects, such as nuclear power plants. The last really strong solar storm took place in the telegraph age, i.e. long before the appearance of PCs. Although astronomers are constantly observing the behavior of the Sun, they can anticipate it only slightly ahead of time. This means that in the future we will have at least 24 hours to disable all sensitive systems (even those in nuclear power plants) and secure computers. But geomagnetic storms are not the only problem facing us by the most important star …

Technological metals – Term introduced in 2007

Technological metals – A concept that is relatively new, in contrast to the actual use of metals in science and industry. The date in 2007 was introduced by American chemist and physicist Jack Lifton. Since then, it is often used in industry. Generally, you can say that the tech. metals are basically precious metals and those that are necessary for the production of hi-tech devices and engineering systems. This category includes:

  • commercial production of miniature electronic devices
  • advanced military systems
  • generating electricity using alternative sources, for example solar panels or wind turbines
  • electricity storage using batteries and cells.

There are of course a lot of other uses of these elements. Almost all technological metals are a by-product of the treatment of basic metals (except for precious and lithium).

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. […] “
