Scientists

Being objective as a scientist means remaining unbiased, impartial, and free from personal beliefs or emotions when conducting research or making conclusions. It involves basing decisions and interpretations on data and evidence rather than personal opinions or preferences. Objectivity is essential in maintaining the integrity and credibility of scientific work.

1. Marie Curie (Poland/France) - discovered radioactivity
2. Albert Einstein (Germany/Switzerland/USA) - theory of relativity
3. Alexander Fleming (Scotland) - discovered penicillin
4. Nikola Tesla (Serbia/USA) - work in electrical engineering
5. Galileo Galilei (Italy) - contributions to astronomy and physics
6. Charles Darwin (England) - theory of evolution
7. Sigmund Freud (Austria) - psychoanalysis
8. Gregor Mendel (Austria/Hungary) - father of genetics
9. Neils Bohr (Denmark) - atomic structure
10. Isaac Newton (England) - laws of motion and gravity

Scientists may reject a theory if new evidence contradicts it, if it fails to make accurate predictions, or if a better theory emerges that explains the data more effectively. Rejection of a theory is a normal part of the scientific process as it leads to the refinement and advancement of knowledge.

Yes, skepticism as a scientific attitude encourages scientists to question and critically evaluate ideas and hypotheses. This helps researchers design experiments that are rigorous and capable of providing clear evidence to either support or reject hypotheses. By constantly challenging assumptions and seeking evidence, scientists can ensure that their experiments are well-designed and capable of generating valid results.

Weight is not a physical property of an object, it is an effect, which varies from place to place. A given object will have the same mass no matter whether it is on the Earth, or on Mars, or somewhere in between.

I can think of a number of ways in which it would be possible to show appreciation for the work of a scientist in the field of electricity. First, learn about the work so that you fully understand it. See if you can build on it or follow lines of research to new and fruitful conclusions. See if you can get the US Post Office to issue a commemorative stamp for this scientist. See if you can get your local school board to name a school after him or her. Print commemorative T shirts. Do a beautiful oil painting of that scientist, with a symbolic background showing relevant electrical phenomena. Create a life sized bronze statue of the scientist. Name your first born child after him or her.

1. Intuition: Answering based on gut feeling rather than evidence or data.
2. Anecdotal evidence: Drawing conclusions from personal experiences rather than systematic study.
3. Circular reasoning: Using the conclusion to justify the premise, leading to a logical fallacy.

Penicillin was discovered by Scottish scientist Alexander Fleming in 1928. Fleming observed that the Penicillium mold inhibited the growth of bacteria, leading to the discovery of the first antibiotic.

Scientists use mercury barometers and aneroid barometers to measure atmospheric pressure. Mercury barometers measure pressure by balancing the weight of mercury against atmospheric pressure, while aneroid barometers use a flexible metal box to detect pressure changes.

Louis Pasteur developed the anthrax vaccine by exposing sheep to weakened anthrax bacteria, observing that they developed immunity against the disease. He then tested the vaccine on a farm and successfully protected sheep from anthrax infection. This method laid the foundation for the development of vaccines based on weakened or attenuated pathogens.

Alexander Fleming enjoyed gardening, painting, and playing the violin in his free time.

Watson and Crick are probably the most obvious example here. They solved the riddle of how genetic information was stored inside our cells. They produced the first model of the 'double helix' structure that everyone now recognises as DNA. In their own words: "We've discovered the secret of life."

Ada Lovelace, a mathematician and writer known for her work on the first algorithm intended for processing by a computer, is one of the scientists whose name starts with the letter "A."

Max Planck used mathematical tools, such as calculus, to develop his quantum theory. He also used experimental tools, such as spectroscopy, to gather data to support his ideas. Additionally, he utilized conceptual tools, like the Planck constant, to help explain the behavior of energy at the atomic level.

Scientists must be logical and systematic to ensure that their experiments are based on sound reasoning and methods. This helps to eliminate bias and errors in their findings, leading to more reliable results. By following logical and systematic approaches, scientists can make robust conclusions and contribute to the advancement of knowledge in their field.

A scientist who studies trees is called a dendrologist or a forestry scientist. They specialize in the study of the anatomy, growth patterns, diseases, and ecological roles of trees.

It was John Dalton in the early 1800s.

No, owning a Tesla coil is not illegal as long as it is used in a responsible manner and complies with local regulations regarding electromagnetic interference and safety. It is important to adhere to safety guidelines when operating such high-voltage equipment.

Galileo Galilee was put on trial for teaching that the Earth was round, which was against Church doctrine concerning the flatness of the Earth.

The movement of electrons around a central nucleus is a concept that was discovered by Niels Bohr in 1913. Bohr's model of the atom revolutionized our understanding of atomic structure and laid the foundation for modern quantum mechanics.

Another name for Pasteur pipette is transfer pipette.

Known as the founder of microbiology, Pasteur discovered the role of bacteria in fermentation. His experiments with bacteria conclusively disproved the theory of spontaneous generation and led to the theory that infection is caused by germs. Extrapolating from this knowledge, Pasteur then developed a process in which liquids such as milk were heated to kill all bacteria and moulds already present within them. This process became known as pasteurisation.

Recognising that infectious diseases are caused by microorganisms, Pasteur's research soon led others to investigate sterilisation, disinfection, vaccines, and eventually antibiotics. Pasteur created and tested vaccines for diphtheria, cholera, yellow fever, plague, rabies, anthrax, and tuberculosis. (source: today.wmit.net - 27 December)

Alexander Fleming's discovery of penicillin in 1928 marked a major breakthrough in medicine and science. Penicillin revolutionized the treatment of bacterial infections and laid the groundwork for future advancements in antibiotics. Fleming's work paved the way for the development of various antimicrobial drugs and greatly improved healthcare outcomes globally.

Yes, Richard Feynman was a drummer and enjoyed playing percussion instruments as a hobby.
