⏹ Humboldt, Friedrich Heinrich Alexander, Baron von
Friedrich Heinrich Humboldt Alexander Baron von

German naturalist and traveler (1769-1859)
Humboldt received his education in «Frankfurt on the Oder» and in Berlin and Gettingen, and at the Mining University in Freiburg. Humboldt made a trip to South America.
It took five years, during which he collected observations and information and came out with results that together greatly enriched scientific knowledge.
Humboldt made a similar trip to Central Asia years later.
Humboldt founded the science of physical geography · He is the first to draw isotherms on maps.
Humboldt brought from South America a sample of the "guano" sediment.
So I knew the fertilizing importance of these sediments. Humboldt's studies included the nature of tropical storms, geomagnetism, and volcanic regions. In his famous book titled: Kosmos in 1846, he tried to give a physical picture of the universe.

This book comes as conclusive evidence of the capacity and talents of the scientist Humboldt.

⏹ Huygens, Christian (Huygens)
Christiaan (Huyghens) Huygens,

Dutch mathematician and physicist (1629-1695)
Huygens received his education in Leiden and Breda, then he turned to scientific research, and succeeded in that clearly, so he was chosen as a Fellow of the Royal Society Huygens studied the properties of the compound pendulum and was the first to use it as a regulator in wall clocks, as he used it to determine the earth's gravitational wheel. Huygens was the first to prove that the ring that surrounds Saturn is complete (see Maxwell, James Clark) and measured the inclination of the plane of Saturn in relation to the ecliptic plane. He was the first to draw Mars and the first to describe the nebula of the constellation Orion (Orion), and he discovered a satellite of Saturn called Iapetus.
Huygens designed an eye lens that reduces the effect of spherical aberration, as he developed in 1678.

The wave theory of light, but it did not receive widespread support for its inability to explain optical polarization, although it explained double refraction in an acceptable way. This theory was opposed to Newton's theory from 1642 to 1727 known as corpuscular theory • The dispute remained between the supporters of these two theories until they united in what is called wave-mechanics. Huygens introduced the use of a new type of air pump equipped with a plate and a semi-conical bowl. · Huygens wrote a number of books around which his work revolved, including his achievements in: Systema Saturnium appeared in 1659, and the wall clock dancer in 1673, atorium Horologium Oscill.

⏹ Hoyle, Fred Hoyle, Fred

English astronomer and mathematician (1915-).
Hoyle received his education in Cambridge, then worked as a lecturer there, then as a professor of astronomy - he wrote a book explaining his views on astronomy and the universe, entitled: The Nature of the Universe in 1952
This was a simple book. Then he wrote a book entitled Frontiers of Astronomy in 1955.
Narlikar Hoyle partnered with the Indian scientist Narlikar
In developing a comprehensive theory of attraction that includes Einstein's theory about the field and the particle as a special case.
Hoyle was elected a member of the British Royal Society.

⏹ Hertz, Gustav Hertz, Gustav

German physicist (1887 - )
He is the nephew of the famous scientist Heinrich Hertz, the discoverer of electromagnetic waves (electro-magnetic) predicted by Maxwell.
Gustav Herz was educated in Göttingen, Munich and Breden. Then he worked as a professor of physics in Halle, then in Berlin, and after World War II in Leipzig.
Hertz shared the Nobel Prize in Physics with Frank as a result of his research on the effects of electrons on atoms.
He was also awarded the Stalin Prize in recognition of his scientific efforts.
