Why is Louis Pasteur important?
Louis Pasteur did many things but is most well-known for discovering how to pasteurise milk (which is where we get the word "pasteurise"). Bacteria in the milk are killed by heating to a specific temperature and then rapidly cooling it down.
Contributions of Francis Bacon and Rene descartes?
Rene Descartes and Francis Bacon are known for their philosophical contributions in the scientific revolution. Descartes contributions are in the areas of science and mathematics. He came up with the reasoning to the issues in these areas which are truth based and incontrovertible. While Francis Baconâ??s Scientific Method stressed on to replace the deductive reasoning by inductive reasoning.
Who were the scientists Enrico Fermi worked with?
You can identify some of them from the article linked.
What were the medical benefits that came from the Holocaust?
The Nazis did medical experiments on the Jews and used them as a way to learn different procedures and health issues. They learned different surgeries, information about hypothermia and starvation, and many more different medical discoveries in dental and other medical fields. One specific thing the Nazis experimented with was trying to change eye color. They were obsessed with making everyone have blue eyes. They also did things like sawing off the forearms and attaching the person's hands to their elbows. The Nazi doctors, later charged with premeditated murder, also came in contact with many different diseases and ailments that they were able to learn about.
How do scientists determine metal composition?
one method is to digest the metal using an acid and then use atomic absorption spectroscopy to determine which metal and how much of that metal is present in the solution. You can then work backwards to determine how much of a particular metal was in your sample (you need to know how much metal was used to make the solution).
Is Earl Kirby a Caribbean Scientist?
Earl Kirby is a veterinarian from St. Vincent. He was famous for his research in many scientific fields, such as veterinary medicine, geology, and vulcanology.
So the atomic number scale that was uncovered by Moseley's work cleared up these anomalies, but did not lead to any changes in the periodic table.
What scientific belief did Francis Bacon and René Descartes share?
That Nature could be explained through abstract reasoning and experimentation.
The scientific belief that Francis Bacon and Rene Descartes shared was their belief that most of the knowledge that came before was weak, sloppy, and in some cases very wrong. They both believed knowledge should be received by personal observation.
What is Planck's constant dimensionally equal to?
Planck's Constant is dimensionally equal to Angular Momentum. The unit is Joules second.
What mistakes did Eisenhower make?
It is hard to tell what mistakes Eisenhower has made as some of them can be subjective. However a commonly listed mistake was being unable to defused the Cold War. It should be noted that he was making good progress with it until an incident beyond his control involving a spy plane undid his work.
What sparked Nikola Tesla's interest into electricity?
During a brief spell studying electrical engineering and mathematics at the Austrian Polytechnic School in Graz, the precocious Tesla developed a passion for Alternating Current and Voltaire. But he never gained his degree, possibly being expelled for dissolute behaviour.
How is hydrogen use by scientists and engineers and artists and doctors?
Well hydrogen can be used for a bomb with a yield larger than a nuke, artists can use it to make bubble sculptures because the bubbles rise but stick together, people can use it for heating purposes (although Idk who would want that amount of energy) and lots of other stuff. Google is a great tool to fnd this out.
Why was Albert Einstein known as a great mathematician?
hes the one who created E=mc2 the two is squared
How do scientists know about the structure of the earth's interior?
Because of the study of seismic waves from earthquakes
List the three most famous scientists of the Hellenistic Age?
Aristarchus found out the planets revolved around the sun, not he sun revolved around Earth.
How did Rene Descartes invent the coordinate system?
Every time you graph an equation on a Cartesian coordinate system, you are using the work of René Descartes. Descartes, a French mathematician and philosopher, was born in La Haye, France (now named in his honor) on March 31, 1596. His parents taught him at home until he was 8 years old, when he entered the Jesuit college of La Flèche. There he continued his studies until he graduated at age 18.
Descartes was an outstanding student at La Flèche, especially in mathematics. Because of his delicate health, his teachers allowed him to stay in bed until late morning. Despite missing most of his morning classes, Descartes was able to keep up with his studies. He would continue the habit of staying late in bed for his entire adult life.
After graduating from La Flèche, Descartes traveled to Paris and eventually enrolled at the University of Poitiers. He graduated with a law degree in 1616 and then enlisted in a military school. In 1619, he joined the Bavarian army and spent the next nine years as a soldier, touring throughout much of Europe in between military campaigns. Descartes eventually settled in Holland, where he spent most of the rest of his life. There Descartes gave up a military career and decided on a life of mathematics and philosophy.
Descartes attempted to provide a philosophical foundation for the new mechanistic physics that was developing from the work of Copernicus and Galileo. He divided all things into two categories-mind and matter-and developed a dualistic philosophical system in which, although mind is subject to the will and does not follow physical laws, all matter must obey the same mechanistic laws.
The philosophical system that Descartes developed, known as Cartesian philosophy, was based on skepticism and asserted that all reliable knowledge must be built up by the use of reason through logical analysis. Cartesian philosophy was influential in the ultimate success of the Scientific Revolution and provides the foundation upon which most subsequent philosophical thought is grounded.
Descartes published various treatises about philosophy and mathematics. In 1637 Descartes published his masterwork, Discourse on the Method of Reasoning Well and Seeking Truth in the Sciences. In Discourse, Descartes sought to explain everything in terms of matter and motion. Discoursecontained three appendices, one on optics, one on meteorology, and one titled La Géometrie (The Geometry). In La Géometrie, Descartes described what is now known as the system of Cartesian Coordinates, or coordinate geometry. In Descartes's system of coordinates, geometry and algebra were united for the first time to create what is known as analytic geometry.

What two substances are needed by plants to make glucose?
carbondioxide+sunlight+water=oxygen+glucose
What was Albert Einstein's contribution to our understanding of photoelectric effect?
He was the first one to successfully explain this effect, and thus created the basic form of what became modern Quantum Mechanics (a theory that in its final form he rejected because it is probabilistic not deterministic).
Note: Einstein did not receive his Nobel Prize for Relativity, but for his work on Brownian Motion and the Photoelectric Effect.
What scientist is considered the leader in evolutionary studies?
It probably varies between scientists to whom the leader (or most influential) in this area is. Although the answer you will hear more often than most is Charles Darwin and his theory of natural selection, which he worked on after an expedition to the Galapagos Islands. With only his notepad, drawings and samples that he took of the creatures he encountered on the Islands, he noted that creatures, those that were the same species, differed depending what Island they were on. For example the Mockingbirds he discovered on different Islands had different sized beaks which suggested they had adapted to a change and evolved. My knowledge is limited on the subject but in my mind he produced the theories which have helped us understand evolution much better, and he did it with a notepad and samples....very limited technology compared to what we have today.
Like I said, I'm no expert I just love anything to do with science and watch a lot of documentaries.
What is the name of subatomic particle named after Indian scientists?
The boson named after Indian physicist Satyendra Nath Bose is called "boson". It is a type of subatomic particle that follows Bose-Einstein statistics and is integral to the field of quantum mechanics.
