Who are the first inventors of microscope which was used to view the cell? A Dutch father-son team named Hans and Zacharias Janssen invented the first so-called compound microscope in the late 16th century when they discovered that, if they put a lens at the top and bottom of a tube and...
The existence of possibly explosive forces in the nuclei of atoms had been known ever since the structure of atoms was discovered by Rutherford. An atom consists of a tiny core called the "nucleus" with attendant electrons circling round it. The hydrogen atom, which is the simplest and ...
which, when it is pure, sets up a chain reaction which spreads like fire, though with enormously greater rapidity. it is this substance which was used in making the atom bomb. the political background of the atomic scientists' work was the determination to defeat the nazis. it was held--...
the heavy hydrogen isotopes Deuterium and Tritium,whichrequire less energy to fuse. The easiest fusion reaction to initiate involves the combination of one Deuterium and one Tritium atom to produce one atom of Helium-4, one free neutron, and 17.6 Mega-electron-volts of energy. The next-easiest...
Is it you or the forth entity like your belonging group or big brother? If you ask me there is no question it is you but unfortunately for large population it is not that simple.To me if an individual has an atom of autonomy to use free will we all have God like powers to make de...

Perhaps no other school could have done as much for Pauling as Caltech did. Without question, he knew this was the place where he belonged, and where he discovered his life’s work. All that had come before was kid stuff, the grunt work of math by rote and the endless repetition of ...
one of the darlings of science and a man with colossal physical and mathematical intuition, even tried to tackle this problem multiple times throughout his career to no avail. This is a man who, at the time, probably understood the inner workings of the atom better than anyone else on Eart...
[In this figure]A collection of “antique” microscope dated to the early development of microscopy. (A) Anton von Leeuwenhoek’s microscope was a simple glass magnifier with only one convex lens. He discovered many microorganisms, such as Paramecium, using this simple microscope. (B) Janssen ...
By the beginning of the 19th century, about 47 elements had been discovered, providing enough data for chemists to begin to see patterns. John Newlands had published his Law of Octaves in 1865. The Law of Octaves hadtwo elementsin one box and did not allowspace for undiscovered elements, s...
