1.Chance favors only the prepared mind.

When meditating over a disease, I never think of finding a remedy for it, but, instead, a means of preventing it.

上面是pasteur说过的话

Fully aware of the presence of microorganisms in nature, Pasteur undertook several experiments designed to address the question of where these “germs” came from. Were they spontaneously produced in substances themselves, or were they introduced into substances from the environment? Pasteur concluded that the latter was always the case. His findings resulted in a fierce debate with the French biologist Félix Pouchet—and later with the noted English bacteriologist Henry Bastion—who maintained that under appropriate conditions instances of spontaneous generation could be found. These debates, which lasted well into the 1870s, although a commission of the Académie des Sciences officially accepted Pasteur’s results in 1864, gave great impetus to improving experimental techniques in microbiology.

2.Mendel’s Laws, principles of hereditary transmission of physical characteristics. They were formulated in 1865 by the Augustinian monk Gregor Johann Mendel. Experimenting with seven contrasting characteristics of pure-breeding garden peas, Mendel discovered that by crossing tall and dwarf parents, for example, he got hybrid offspring that resembled the tall parent rather than being a medium-height blend. To explain this he conceived of hereditary units, now called genes, which often expressed dominant or recessive characteristics. Formulating his first principle (the law of segregation), Mendel stated that genes normally occur in pairs in the ordinary body cells, but segregate in the formation of sex cells (eggs or sperm), each member of the pair becoming part of the separate sex cell. When egg and sperm unite, forming a gene pair, the dominant gene (tallness) masks the recessive gene (shortness).

To corroborate the existence of such hereditary units, Mendel went on to interbreed the first generation of hybrid tall peas and found that the second generation turned out in a ratio of three tall to each short offspring. He then correctly conceived that the genes paired into AA, Aa, and aa (“A” representing dominant and “a” representing recessive). Continuing the breeding experiments, he found that the self-pollinated AA bred true to produce pure tall plants, that the aa plant produced pure dwarf plants, and that the Aa, or hybrid, tall plants produced the same three-to-one ratio of offspring. From this Mendel could see that hereditary units did not blend, as his predecessors believed, but remained unchanged from one generation to another. He thus formulated his second principle (the law of independent assortment), in which the expression of a gene for any single characteristic is usually not influenced by the expression of another characteristic. Mendel's laws became the theoretical basis for modern genetics and heredity.

3.If I have seen further it is by standing on the shoulders of giants.

5.Fleming conducted outstanding research in bacteriology, chemotherapy, and immunology. In 1922 he discovered lysozyme, an antiseptic found in tears, body secretions, albumen, and certain fish plants. His discovery of penicillin came about accidentally in 1928 in the course of research on influenza. His observation that the mold contaminating one of his culture plates had destroyed the bacteria laid the basis for the development of penicillin therapy

6.X rays were discovered accidentally in 1895 by the German physicist Wilhelm Conrad Roentgen while he was studying cathode rays in a high-voltage, gaseous-discharge tube. Despite the fact that the tube was encased in a black cardboard box, Roentgen noticed that a barium-platinocyanide screen, inadvertently lying nearby, emitted fluorescent light whenever the tube was in operation. After conducting further experiments, he determined that the fluorescence was caused by invisible radiation of a more penetrating nature than ultraviolet rays He named the invisible radiation “X ray” because of its unknown nature. Subsequently, X rays were known also as Roentgen rays in his honor.

7.Curie, Marie (1867-1934), Polish-born French chemist who, with her husband Pierre Curie, was an early investigator of radioactivity. Radioactivity is the spontaneous decay of certain elements into other elements and energy. The Curies shared the 1903 Nobel Prize in physics with French physicist Antoine Henri Becquerel for fundamental research on radioactivity. Marie Curie went on to study the chemistry and medical applications of radium. She was awarded the 1911 Nobel Prize in chemistry in recognition of her work in discovering radium and polonium and in isolating radium
