Marie Curie Marie Curie Marie Curie was born in Warsaw on November 7, 1867. She was actually born to the name Marja Sklodowska. When she was 24, she went to Paris where she changed her name to Marie and started school in Sorbonne. In 1893, she received her degree in physics. When she needed a lab to experiment in, a Professor Kovalski said that there might be space in the School of Physics and Chemistry. He also said that Pierre Curie, a scientist there might be able to help her. She had heard o

marijuna Marijuana, the crude drug made from the leaves and flowering tops of the cannabis sativa plant, contains hundreds of active chemicals. Of the 421 chemicals identified in the plant, 70 are cannabinoids (chemicals found only in the marijuana plant and nowhere else in nature). Cannabinoids are stored in the fat parts of cell membranes for long periods of time and interfere with normal cell functioning. Since the 70 annabinoids are fat-soluble, they build up or accumulate in body tissue. Th
MPD Multiple Personality Disorder (MPD) or Dissociative Identity Disorder (DID) was first acknowledged in the 1700\'s but was not understood so therefore it was forgotten. Many cases show up in medical records through the years, but in 1905, Dr. Morton Prince wrote a book about MPD that is a foundation for the disease. A few years after it was published Sigmund Freud dismissed the affliction and this dropped it from being discussed at any credible mental health meetings. Since then the disorder

nanotechnology Computers reproduce information at almost no cost. A push is well underway to invent devices that manufacture at almost no cost, by treating atoms discretely, like computers treat bits of information. This would allow automatic construction of consumer goods without traditional labor, like a Xerox machine produces unlimited copies without a human retyping the original information. Electronics is fueled by miniaturization. Working smaller has led to the tools capable of manipulatin
Neil Armstrong Neil Armstrong When Neil Armstrong was two years old he loved going to the Airport to watch the planes take off and land. He got so excited just watching. When he was five years old he pretended that he was hovering over his bed. He wanted to fly! He loved airplanes and at six years old he had his first airplane ride. He was so smart in school that they moved him from second grade into third grade because he was reading at a fifth grade level. Every airplane book he got his hands
Nernst bio Walther Hurmann Nernst was born in Briesen, West Prussia, on June 25, 1864. His father, Gustav Nernst, was a district judge. He spent his early school years at Graudentz, and subsequently went to the Universities of Zurich, Berlin and Graz, studyin physics and mathermatics, before proceeding to Wurzburg, where he graduated in 1887 with a thesis on electromotive forces produced by magnetism in heated metal plates. He joined Willhelm Ostwald at Leipzig University, where van\'t Hoff and
nitroglycerine Nitroglycerin (C3H5N3O9) Nitroglycerin is one of the most sensitive explosives ever to be commercially produced. It is a very dense liquid, and is sensitive to heat, impact, and many organic materials. Although it is not water soluble, it will dissolve in 4 parts of pure ethyl alcohol. Heat of Combustion: 1580 cal/g Products of Explosion: Carbon Dioxide, Water, Nitrogen, Oxygen Human Toxicity: Highly toxic vasodilator, avoid skin contact! Although it is possible to make it safely,

ozone depletion The Earth’s ozone layer shields all life on the planet from the sun’s harmful radiation and is extremely important to all life on the planet, but we as a human race are now faced with a very important question. This question is, “Is the Earth’s ozone layer really depleting, and if it is, is it really a threat?” There is evidence that less protection from ultraviolet rays will, over time, lead to increased amounts skin cancer, cataract, and even crop damage. With cooperation with

Pasteur PASTEUR, Louis (1822-95). The French chemist Louis Pasteur devoted his life to solving practical problems of industry, agriculture, and medicine. His discoveries have saved countless lives and created new wealth for the world. Among his discoveries are the pasteurization process and ways of preventing silkworm diseases, anthrax, chicken cholera, and rabies. Pasteur sought no profits from his discoveries, and he supported his family on his professor\'s salary or on a modest government all

Schizophrenia and its causes Introduction In the search to find out what schizophrenia is and its causes, researchers have now determined that schizophrenia is a neurological or physical brain disorder as opposed to earlier diagnosis as mental disorder. These questions have plagued everyone who has had contact with someone with schizophrenia, from the public to the medical profession alike. It is now clear that schizophrenia is caused by a brain defect. People with schizophrenia show a number of
Sensroy Evaluation Sensory analysis is the measurement of consumer responses to sensory stimuli. It is used in grading, consumer preferences, quality assurance, shelf life testing, product development and research. The food industry probably has the greatest number of sensory analysts ranging from specialist wine, beer, and tea tasters to researchers investigating how consumers perceive flavors and textures. Sensory analysts also work in the cosmetics, toiletries and household care products indu

A lot of the talk circulating these days is focused on self well-being.

His attempts to identify a grand unification theory that unites everything we know about the physical world and science far exceeds any realm of thinking that has ever graced this earth.

Stereochemistry Considerations Stereochemistry Considerations What would you think if I gave you a drug and said this is going to help you but I want you to know ahead of time that 50% of the dose is not affected, in fact the drug is 50% not pure. The idea of that would make you feel you want another drug. The reality of that is that a large # of drugs we give are 50% impure and the reason is b/c so many drugs we give are racemic mixtures, a 50:50 mixture of enantiomers. Most drugs that demonstr

television depiction of family life Changes in the Family Ross T. Crooks October 22, 2000 Over the past 50 years, the traditional structure of the family has evolved tremendously. The role of each member has changed in many ways. This creates an entirely different chemistry within the family. In the 1950’s, the traditional family was composed of a father, mother, and the children that they created within the marriage. The father was usually the disciplinarian and financial provider for the famil

the ocean and its priperties The oceans are said to be the “source of life.” The enormous, blue, calm oceans are the signatures of the planet earth. They cover nearly three-fourths of the surface of the earth. This is equal to 71 percent of the earth’s entire surface or about 361 million sq km (140 million sq mi). Its average depth is 5000 m (16,000 ft), and its total volume is about 1,347,000,000 cu km (322,300,000 cu mi). This includes the Atlantic, Pacific, and Indian oceans. These oceans are

Maybe that is why, as a whole, we have such a difficult time discerning between the two, or rather, why we fail to see clearly the true meaning that l
Thomas Edison1 Thomas Alva Edison Thomas Alva Edison was one of the greatest inventors. He was a smart man. Thomas invented many things such as the light bulb and phonograph. Without the light bulb we would still be using candles and lanterns like they did many years ago. Although Thomas was deaf he worked hard and never gave up. Thomas Alva Edison was born on February 11, 1847 in Milan, Ohio. He had many family members. He had a father named Samuel Odgen Edison and a mother named Nancy Elliott

Jazz in New York and Chicago During the 1920s New York and Chicago During the 1920\'s The 1920\'s was a huge decade for the phenomena known as Jazz. Due to the closing of the seaport in New Orleans, musicians were forced to travel up the Mississippi to find work. Two of the cities most affected by this move were Chicago and New York. Chicago was home primarily for New Orleans traditional music during the 1920\'s. From this New Orleans style came four major types of jazz: Boogie-Woogie, Chicago
