He then applied for the Ecole Normale Sup Rievre in Paris. There he would study under Dumas, Balard and Biot. His first work was done on crystals. Pasteur refused to accept Mitscherlich dictum about crystals. He was convinced that two compounds that had the same chemical compound but reacted to the rotation of light differently could be identical. The internal structure of the two compounds must be different and this was showed in crystal form. When examining the paratartrate crystals he found they were almost identical, but not quite. They were mirror images. He then separated the left and right crystals with a microscope and dissecting needle. After completion he had two piles, one from the left side and one from the right side. He then showed that in solution one form rotated to the left and the other to the right. This proved that organic molecules with the sam
