Radioactive decay In the 19th century, Henri Becquerel discovered that some chemical elements have atoms that change: During their change they send out a particle. In 1898, Marie and Pierre Curie called this phenomenon radioactive decay. Becquerel and the Curies were awarded the Nobel Prize in Physics for this discovery, in 1903.

The Bessemer Process Discovered in 1855 by Sir Henry Bessemer. The Bessemer process was discovered through Sir Henry’s attempts to manufacture steel faster and more cheaply. Particularly for the purpose of manufacturing military weapons, which were at the time made with iron, which is considerably heavier than steel.

- The Casco Viejo of Bilbao is also locally known as “las 7 calles” in Spanish or “Zazpi Kaleak” in Basque (the seven streets), since these were the seven streets that formed the original medieval town. Today, it is still the heart of the city and probably its most colorful neighborhood.

- The becquerel (symbol: Bq) is the SI derived unit of radioactivity. One becquerel is defined as the activity of a quantity of radioactive material in which one nucleus decays per second. The becquerel is therefore equivalent to an inverse second, s−1.

Periodic table history He predicted the discovery of other elements, and left spaces open in his periodic table for them. In 1886 French physicist Antoine Bequerel first discovered radioactivity. Thomson student from New Zealand Ernest Rutherford named three types of radiation; alpha, beta and gamma rays.

Biography On Anton Van Leeuwenhoek History Essay Animacules or microorganisms, as we refer to them today was the term that he coined to those single-celled organisms that he first observed and described using his handcrafted microscopes. Leeuwenhoek was also the first to document minuscule examination of muscle fibers, bacteria, spermatozoa, and most essential, the flow of blood in capillaries.

- History of Radiography. X-rays were discovered in 1895 by Wilhelm Conrad Roentgen (1845-1923) who was a Professor at Wuerzburg University in Germany.Working with a cathode-ray tube in his laboratory, Roentgen observed a fluorescent glow of crystals on a table near his tube.hortly after the discovery of X-rays, another form of penetrating rays was discovered. In 1896, French scientist Henri Becquerel discovered natural radioactivity. Many scientists of the period were working with cathode rays, and other scientists were gathering evidence on the theory that the atom could be subdivided.

Marie and Pierre Curie and the Discovery of Polonium and  Radium The Story: Madame Marie Curie was the world s most famous woman scientist--and so she remains today. With her husband, Pierre Curie, and the French physicist Henri Becquerel, and later on her own, Curie pioneered the study of radioactivity (a word she coined). Marie Sklodowska, as she was called before marriage, was born in Warsaw in 1867.

Antoine Lavoisier Antoine Lavoisier. Antoine Lavoisier was a French chemist who helped develop the science into its modern form. He is frequently considered the “father of modern chemistry,” and he was responsible for naming the elements hydrogen and oxygen. He was also one of the supporters of the metric system of measurements. Lavoisier, as a tax collector and nobleman, was arrested after the French Revolution and was executed in 1794.

What Eats Frogs in a Freshwater Biome? Frogs and tadpoles alike fall prey to a wide variety of birds and reptiles. Many kinds of birds who live in and around freshwater biomes can eat smaller frogs and tadpoles. Large bullfrogs are safe from all but the bigger birds, such as herons. Common avian predators of frogs include ducks, geese, swans, wading birds, gulls, crows, ravens and hawks. Frogs are also at risk of becoming a meal for garter snakes, water moccasins and other swimming snakes.
