Scientists

Louis de Broglie was the scientist who proposed the hypothesis of wave-particle duality. This idea helped to further the development of the theory of atomic structure, particularly in understanding the behavior of electrons within atoms.

Pedro Escuro is a character in Philippine mythology. He is known as a very tall and dark-skinned enchanted being who roams the forest at night. Some stories depict him as a benevolent creature who helps people in need, while others portray him as a mischievous trickster.

yes, actually he did...... he had 3 kids with his wife.... this was found in the birth records of Vienne, Austria..

Dmitri Mendeleev is credited with creating the Periodic Table of Elements in 1869. He arranged elements by increasing atomic weight and noticed periodic trends in their properties which led to the development of the modern periodic table.

The scientist who is credited with discovering oxygen is Joseph Priestley, an English chemist and clergyman. He isolated oxygen in 1774 by heating mercuric oxide and noting the release of a gas that enhanced combustion.

There is no widely known information about Alexander Fleming's favorite color.

Richard Feynman made significant contributions to the development of quantum electrodynamics, particularly in the formulation of his diagrams which are now known as Feynman diagrams. His work helped to revolutionize the field of theoretical physics and earned him the Nobel Prize in Physics in 1965. Feynman also made key contributions to the understanding of superfluidity, the theory of weak interactions, and the dynamics of liquid helium.

The push-pull theory is used by scientists to explain how certain chemical signals attract or repel cells or molecules to guide their movement and positioning within biological systems. It helps to understand processes such as cell migration, neural development, and the establishment of tissue patterns during embryonic development.

Friedmann Theory - Alexander Alexandrovich Friedmann is best known for his pioneering theory that the universe was expanding, governed by a set of equations he developed from Albert Einstein's equations of general relativity, showing that the Universe might be expanding in contrast to the static Universe model advocated by Einstein at that time. From these equations he postulated three Friedmann models describing positive, zero and negative curvature respectively. This dynamic cosmological model of general relativity would come to form the standard for both the Big Bang and Steady State theories.

However it was Georges Lemaître, a Belgian physicist and Roman Catholic priest, who, in 1927, independently used Friedmann's equations to propose that the inferred recession of the spiral nebulae (per Edwin Hubble's discovery of 1924) was due to the expansion of the Universe. As such, the Jesuit priest Georges LeMaitre was credited with being the first to mathematically detail a cosmological study now known as the Big Bang.

Though history books continue to give Guglielmo Marconi credit for the invention of radio, Tesla's lectures on wireless broadcasting precede Marconi's radio patents by some three years. The U.S. Supreme Court ruled on the matter in Tesla's favor, and struck down Marconi's patent claim, in 1943.

An example of a metal that is made up of more than one element is bronze, which is an alloy composed mainly of copper and tin. Alloys are materials that contain a mixture of elements, with at least one of them being a metal.

Spectroscopy is the tool that allows scientists to see patterns of carbon molecules by analyzing the way they interact with light.

Alexander Fleming discovered penicillin, he left it in a petri dish for 2 weeks whilst he was on holiday when the got back there was a ring shape of mould, he then tested it on 8 mice and 4 were given penicillin they lived, four weren't and they died! To me this answer is good as it helped four mice survive, it also helped soldiers get better in world war 1!

S.Chandra sekar received the 1983 Nobel Prize in physics. Chandra's uncle, SIR.C.V.RAman, received the 1930 Nobel Prize in physics for discovering the Raman effect, which describes the diffraction of light by crystals. Raman was the first Asian to receive a Nobel Prize in science.

Scientists can ignore intermolecular forces in a gas under ordinary conditions because gases have weak forces of attraction compared to liquids and solids. The particles in a gas are far apart and move freely, resulting in negligible interaction between individual particles. Hence, the effects of these weak forces are often minimal and can be disregarded for many practical purposes.

Sir Alexander Fleming was never awarded the Nobel Peace Prize. But he was awarded, jointly with Florey and Chain, the 1945 Nobel Prize for Physiology and Medicine.

Louis Pasteur was a French chemist and microbiologist who is often depicted with his signature bald head and long beard in historical photographs and paintings. He had a stern and focused expression in many of his portraits, reflecting his dedication to scientific research and discoveries.

Physical scientists ask questions about the natural world and how it works. They explore topics like the composition of matter, the forces that govern nature, and the behavior of particles at the smallest scales. Their questions often seek to understand the fundamental laws that govern the universe.

Engineers and scientists use newtons as the standard unit of force because force is a vector quantity that includes both magnitude and direction. Newtons can directly represent this vector nature of force, whereas kilograms are a unit of mass and do not inherently imply directionality. Using newtons makes it easier to accurately describe and calculate forces in equations and models.

Since hydrogen only has one electron that constantly absorbs and emits energy while transitioning back and forth through its energy levels, Bohr realized that each of hydrogens orbits was quantized only allowing an electron of specific energy, frequency & wavelength, to occupy it. So he deduced that hydrogen only has a specific line spectum, thus it has specified "orbits" rather than "orbitals" of probability distribution of electrons.

One of the prominent name of Greek weather scientist is Theophrastus. Theophrastus compiled a book on weather forecasting, called the Book of Signs.

Sir Isaac Newton formulated the law of gravity in the 17th century. He proposed that every object in the universe is attracted to every other object by a force called gravity, which depends on the mass of the objects and the distance between them.

There will be 125 atoms of Na24 remaining in the sample after 45 hours. This calculation is based on the fact that after 3 half-lives (45 hours/15 hours per half-life), the original 1000 atoms would have reduced by a factor of 2 three times, resulting in 1000/2/2/2 = 125 atoms remaining.
