The results provided during the early and mid 1900s such as the Schrödinger equation and Heisenberg uncertainty principle enable virtually everything chemistry related today. The fields of pharmaceutical chemistry and polymer science(plastics especially) would still be in their infancy if not for the work on quantum mechanics

Max Karl Ernst Ludwig Planck Max Karl Ernst Ludwig Planck was a German theoretical physicist who was born on April 23rd‚ 1858 in Kiel‚ Holstein. His parents‚ Johann Julius Wilhelm Planck and Emma Patzig‚ baptized him with the name of Karl Ernst Ludwig Marx Planck‚ but some ten years later he was signed with the primary name of Max. During his early childhood‚ around the age of 6‚ Prussia and Austrian troops marched into Kiel in the Second Schleswig War in 1864. A short three years later‚ the Planck

Think about what educational system was like in the early 1900’s. Now think about the educational system today. The educational system has changed substantially since the introduction of public education in the mid to late 1800’s to the modern day educational system that many of us are aware of today. Back in the old days schools used to be equipped with slide rulers‚ chalkboards‚ and typewriters. Now modern day schools are equipped with electronic calculators‚ smartboards‚ and computers. However

In ancient China‚ many different rulers tried to unify and rule the country using a variety of methods – Confucianism‚ Daoism‚ and Legalism to name a few. Each philosophy had its own set of rules of how people should act both in public and privately. The overall goal of each philosophy was to set a standard of acceptable living that would ensure harmony and success for the society. However‚ each was different and thus had different results. The best way for the people of China to succeed in a harmonious

happens‚ physically‚ when someone makes a measurement. Suppose you’ve flipped a coin at t1 and haven’t looked at the result yet; it’s apparently in a superposition2 of Heads and Tails.3 You’ll look at the result at t2. Here’s what an analogue of the Schrödinger equation would say about what happens: t1: The coin is in a superposition: a combination of 50%-Heads and 50%-Tails. Then … t2: You are in a superposition: a combination of 50%-observing-Heads and 50%-observing-Tails. Of course‚ no one

Discovery of DNA Erwin Chargaff: Chargaff was an Austrian biochemist‚ he was best known for “Chargaff’s Rules” which lead to the discovery of DNA’s double helix structure. He immigrated to New York and secured a position as a research associate in the biochemistry department at Columbia University. Became a full-fledged professor in 1952. He used chromatographic techniques in his research. It was in the U.S.‚ 1950’s where he was able to make the crucial elements‚ in which lead to the formation

required the development of quantum mechanics in the 1920s. Even in its preliminary state‚ the model is good enough for many calculations in astronomy‚ chemistry‚ and other fields‚ saving the trouble of performing often-complex calculations with the Schrödinger equation. This conceptual and mathematical simplicity keeps the Bohr model relevant. Despite a century of work‚ atomic physics is not a quiet field. Researchers continue to probe the structure of atoms‚ especially in their more extreme and exotic

Mental disorders are categorized as “…insanity‚ a source of shame‚ or a lack of self-discipline…” (Erwin‚ Huang & Lin 2002 pp. 623).
