⏹ Lebedev, Peter Nikolaevich
Lebedev, Peter Nikolajevich

Russian physicist (1866 - 1912)
Lebedev was taught by Kundt in Strasbourg and then worked as a professor of physics in Moscow.
Use a Crookes device to bedev
To measure the radiations to prove that light has pressure on objects, and he also explained that the pressure of light on reflective surfaces is double the value it would reach if it fell on light-absorbing surfaces.

⏹ Lichtenberg: Georg Christoph

German physicist and satirist (1742-1799)
Lichtenberg is best known for his experimental studies in physics, especially in the field of electricity. He discovered the shapes known as the Lichtenberg Figures, which arise from the discharge of the accident on the surface of
An insulating plate like glass when one of its surfaces is connected to the ground and the other surface has an electrode at a high voltage. The shapes differ according to the polarity of the electromagnet, and they are either stellar or branched, and in the form of circles whose diameters can be measured to roughly know the voltage on the plate. In addition to his research in physics, he wrote satirical critical literary writings.

⏹ Levell, Sir Alfred Charles Bernard
Lovell, Sir Alfred Charles Bernard

British astronomer (1913 - )
He studied Physics in Bristol and then worked as an assistant lecturer in Manchester. He also worked on the Board of the Telecommunications Research Corporation. He also worked at the experimental station at Godrel Bank and in Cheshire, and was a major official in setting up a radio astronomical telescope with a diameter of two hundred and fifty feet, which was completed in 1957.
After that, he held the position of Professor of Radio Astronomy in Manchester, and he was chosen as a Fellow of the Royal Society, and he was awarded the title of Knight.
He has many important specialized astronomical researches.
In addition to that, he has simplified scientific writings addressed to the educated reader, which he used to publish in newspapers and magazines. Among his simplified works is the book: The Individual and the Universe.

Clanche, George
, Leclanché Georges

French chemist (1839 - 1882)
Clanche would not have become famous as a chemist had it not been for his invention of the electric column that bears his name, which is an electric cell that mainly contains zinc (zinc), ammonium chloride and manganese dioxide. It is considered a complex chemical cell.

Lecles, Charles de: (Lecles, Clausius)

Lecluse, Charles de
(Clusius Lescluse, Lat.)

French botanist and traveler (1524-1609)
Claus (Clausius) was famous for his many trips to study plants, and he is credited with introducing the potato to Europe. It is noteworthy that this work is also attributed to Cardan. The potato plant was mentioned in a book drawn up by Cleese in 1588, and the name Cleese is given to a type of tree, Clusia.

Lennard, Philip Vaughn
Lenard, Philip Von

German physicist (1862 - 1947)
Learn to Nard in Heidelberg at the hands of the world. the famous Bunsen; Then he became a professor of physics there.
He was awarded the Nobel Prize for Physics in 1905.
Lnard is famous for his research on cathode rays and has written several books in this field and on relativity and other related topics. He accuses Lennard of being enthusiastic about Nazism.

Lnard-Jones, Sir John Edward
Jones, Edward Lennard Sir John

English chemist and physicist (1894- )
He studied for Nard-Jones in Manchester and Cambridge, then held a number of educational chairs in physics and mathematics in Bristol, then worked as a professor of theoretical chemistry in Cambridge. He worked for the British government as a “first scientist” during the war.
The studies of Nard-Jones included surface chemistry, coal chemistry (carbon), liquid structure, and interatomic forces.
