who was the person to write the first cell theory?
831982
Well.. cells were first discovered by a man by the name Robert Hooke in 1663. He made the first microscope and saw MANY types of cells. Then two or three individuals formed the cell theory into three man parts.\n\nOne was Matthias Schleiden...another...Theodor Schwann .\n\nThe three basic parts to the cell theory are:\n1. Cells are the basic unit of all living things.\n2. Every living thing has one or morecells.\n3. All cells come from other cells.\n\nGlad to help\n\n~LG23~

Using his handcrafted microscopes he was the first to observe and describe single celled organisms, which he originally referred to as animalcules, and which we now refer to as microorganisms. He was also the first to record microscopic observations of muscle fibers, bacteria, spermatozoa and blood flow in capillaries (small blood vessels).

Fact of the Day: The big bang theory was proposed by a Father Georges-Henri Lemaître (July 17, 1894 – June 20, 1966) was a Belgian Roman Catholic priest and astronomer. \n\nI'm an engineer and as such I believe in creation through design :)

einstein. he just sat in his chair and thought of theories. he did experiments in his mind

Louis Pasteur . He \n\ndiscovered that the purpose of cell division was reproduction. Also learned that living cells are dynamic. They use and produce energy and materials. Fermentative ability of microorganisms demonstrated between 1857 and 1876 by Pasteur - the father of biotechnology.

Two things:\nMarcello Malpighi describes in De cerebro how the nervous system consists of bundles of fibers connected to the brain by the spinal cord.\nRobert Hooke's Micrographia, with illustrations of objects viewed through a microscope, appears. The book greatly influences both scientists and educated laypeople. In it, Hooke describes cells (viewed in sections of cork) for the first time.

1- Albert Eienstien ( His work in explaining the electrophotonic cell based on quantum mechanics)...note: this is not his greatest work, the theory of relativity is more important but it was not understandable by other scientists that time.\n\n2- Maxwell ( His work in establish the Electromagnetic Theory ).\n\n3- NIELS BOHR (for his services in the investigation of the structure of atoms and of the radiation emanating from them)\n\n4- WERNER HEISENBERG (for the creation of quantum mechanics, the application of which has, inter alia, led to the discovery of the allotropic forms of hydrogen)\n\n5-  WOLFGANG PAULI (for the discovery of the Exclusion Principle, also called the Pauli Principle)

The father of modern microbiology, Anton Van Leeuwenhoek created the first simple microscope ( single lensed ) and Robert Hooke created the compund microscope ( Light microscope )

The nucleolus suborganelle was originally discovered in eels by the Italian scientist Felice Fontana in 1774. He was able to see the large, darkly stained nucleolus under a simple light microscope. However, its function wasn't discovered until two centuries later.

Evolution is a theory developed by Charles Darwin to explain the creation of life. \n\nHe believed that man originated from a single-celled organism that combined with another single-celled organism to create the first dual-celled organism.

English physician and physicist who established the principle of interference of light and thus resurrected the century-old wave theory of light. He was also an Egyptologist who helped decipher the Rosetta Stone (see photograph).\n\nIn 1799 Young set up a medical practice in London. His primary interest was in sense perception, and, while still a medical student, he had discovered the way in which the lens of the eye changes shape to focus on objects at differing distances. He discovered the cause of astigmatism in 1801, the same year he turned to the study of light.\n\nBy allowing light to pass through two closely set pinholes onto a screen, Young found that the light beams spread apart and overlapped, and, in the area of overlap, bands of bright light alternated with bands of darkness. With this demonstration of the interference of light, Young definitely established the wave nature of light. He used his new wave theory of light to explain the colours of thin films (such as soap bubbles), and, relating colour to wavelength, he calculated the approximate wavelengths of the seven colours recognized by Newton. In 1817 he proposed that light waves were transverse (vibrating at right angles to the direction of travel), rather than longitudinal (vibrating in the direction of travel) as had long been assumed, and thus explained polarization, the alignment of light waves to vibrate in the same plane.\n\nYoung's work was disparaged by most English scientists: any opposition to a theory of Newton's was unthinkable. It was only with the work of the French physicists Augustin J. Fresnel and François Arago that Young's wave theory finally achieved acceptance in Europe.\n\nYoung also studied the problem of colour perception and proposed that there is no need for a separate mechanism in the eye for every colour, it being sufficient to have three—one each for blue, green, and red. Developed later by the German physicist Hermann L.F. von Helmholtz, this theory is known as the Young–Helmholtz three-colour theory.\n\nHaving become interested in Egyptology, Young began studying the texts of the Rosetta Stone in 1814. After obtaining additional hieroglyphic writings from other sources, he succeeded in providing a nearly accurate translation within a few years and thus contributed heavily to deciphering the ancient Egyptian language.\n\nYoung also did work on measuring the size of molecules, surface tension in liquids, and on elasticity. He was the first to give the word energy its scientific significance, and Young's modulus, a constant in the mathematical equation describing elasticity, was named in his honour.

Corpuscular theory- that light is made up of particles.  Although some ancient Greek philosophers postulated that light was made up of particles, this hypothesis is most strongly associated with Isaac Newton.\n\nWave theory- that light is a wave phenomenon.  Again, many people are associated with this idea, but the first to put it on a solid mathematical footing is Christian Huygens.  Maxwell did not discover the wave theory of light so much as explain it.  He linked light with electromagnetism, by showing that electromagnetic theory predicted the existence of waves with the properties exhibited by light waves.\n\nQuantum theory of light- that light is "quantized", that is, it only comes in certain discrete amounts, and that these quanta, called photons, obey certain probabilistic laws.  This theory has it's origins in the work of Planck, who showed that energy in certain situations was quantized, and Einstein, who applied this energy quantization to light to explain the photoelectric effect.

You seem to have answered your own question there. Nobody knows exactly how the first living cell formed, of course, but it is generaly thorized to have begun with self-replicating molecules (RNA&DNA, like you said, though, belive RNA is belived to be the more ancient). These molecules reacting in a dense enough solution with the nesesary ingridients and enough energy thrown itno the mix, and hey persto -Life!

The theorem (that every real integer can be written as the sum of four squares) was first stated (or enunciated) by Diophatus, the "father of algebra", around 1,800 years ago.  It may have been solved by Pierre de Fermet in 1638, but the first known, published proof was that of Joseph Lagrange in 1770.
