Asked in Science, Scientists

What is the scientific attitude and what attitudes and characteristics define a good scientist?

User Avatar
A good scientist should possess the following qualities: 1. A scientist must be curious about the world Example: Galileo Galileo's curiosity about the heavenly bodies made him the first person to use a telescope to study the moon, the sun, the planets and the stars. 2. A scientist is logical and systematic Example: Among the reasons why Gregor Mendel discovered the principles of heredity when others have failed was his logical experimental methods and his careful and accurate record keeping. 3. A scientist is open-minded and free of bias Example: An open-minded person is one who can modify plans or discard hypotheses if necessary. One such person was Johannes Kepler who was hired to develop evidence that planets moved along perfect circles. 4. A scientist is intellectually honest Example: Isaac Newton built his laws of motion on the previous work of Galileo and others. 5. A scientist works hard and is persistent Example: Marie Curie was the first person ever to be awarded the Nobel Prize twice. It was not surprising considering how hard she worked. 6. A scientist does not jump to conclusions Example: John Dalton's atomic theory was backed by experimental evidence. He was not the first to propose that the atom was the smallest particle of matter, but he was the first to use experimental evidence to support his theory. 7. A scientist is a creative and critical thinker Example: Albert Einstein was able to derive his theory of relativity because he went beyond what was given and known at that time. He saw links and connections where others did not. He looked at things from different perspectives. 8. A scientist is rational 9. A scientist is willing to suspend judgment until he is sure of his results 10. A scientist tries new approaches to arrive at solutions In addition: A scientist must have an open mind and be curious. It is fine to have an idea about how or why something is the way it is, but the scientist should then seek to prove or disprove this "hypothesis" and should then be willing to change their ideas depending on the results of their experiments, rather than to continue believing in their original idea even if the evidence of their experiments is sticking up against it. 1.Keen Observer 2.creative 3.patient 4.curious 5.humble 6.intellectually honest 7.objective 8.Aware of the limitations of Science 9.Persevering 10.Open minded

Asked in Scientists

Who first coined the word satellite?

User Avatar
Satellite comes via French satellite from Latin satelles 'attendant,escort', which itself probably went back to Etruscan satnal. Its use for a 'body orbiting a planet' is first recorded in English in 1665, and comes from the astronomer Johannes Kepler's application of Latin satelles to the moons of Jupiter.
Asked in Religion & Spirituality, Philosophy and Philosophers, History of Science, Math History, Scientists, Mathematicians, René Descartes

Why did René Descartes believe in god?

User Avatar
One of his reasons for believing in god is that he knows (or thinks) that God is perfect. Since perfection includes existence, he therefore assumes that God must exist. Answer: Descartes made a series of increasingly unsupportable suppositions to back up his beleief in God: 1. I exist (A supportable statement for an individual - Cogito ergo sum) 2. I have in my mind the notion of a perfect being (The idea that anyone can develop an idea of a perfect being is not provable. The Aztec may have thoght their bloodthirsty gods perfect as well) 3. An imperfect being, like myself, cannot think up the notion of a perfect being (There is no proof although it is believable that humans are not perfect and it is debatable if the idea he has of a perfect being is indeed perfect) 4. Therefore the notion of a perfect being must have originated from the perfect being himself (This is a flight of fancy) 5. A perfect being would not be perfect if it did not exist (Buddhists, for example see perfection in the loss of being) 6. Therefore a perfect being must exist (This does not follow from any of the above statements)

Why do scientists consider a hypothesis valuable?

User Avatar
Any idea about how an unknown phenomenon occurs, or a simpler explanation for a known one, is useful in figuring out what exactly makes it happen. If it works, it can be tested and refined to provide a better explanation; if not, it OS one further things we know doesn't work.
Asked in Thomas Edison, Scientists, Nikola Tesla

Why did Nikola Tesla leave Thomas Edison?

User Avatar
Edison was working on an direct current motor when Tesla began working for him. He couldn't make it work properly and he offered 50 thoundands dollars if he could fix the machine. That was a easy job for Tesla. Once he finished it, Edison took the offer back stating that it was a joke. Tesla took off inmediatly. The next thing Edison did, he took the patent for the direct current motor.
Asked in Physics, Scientists, Quantum Mechanics, Time Travel

What type of physicist studies time travel?

User Avatar
Theoretical physicist more than likely. As far as time travel I fear physicists have already discovered what is worth to be know. Travel towards future is in principle possible. It is sufficient to move with a speed near the light speed with respect to the starting inertial reference (the earth for one of us). The relativistic phenomenon of time compression provoke the time to pass much slower for the traveler with respect to the persons remaining in the "fixed" reference. When the traveler returns in the initial reference (the earth in our example) he effectively traveled towards the future. Unfortunately, travel towards the past is effectively impossible due to the causal nature of the laws of physics. As a matter of fact, reversing the time in only one phenomenon (the travel of our traveler in this case) violate the essential law of relativity that causal order has to survive between events happening in the same point of the space. Thus it is simply impossible. (look, I'm not going to retype his entire response but: e-mc^2 thus a particle with a negative mass will go at a negative velocity and thus backwards in time. such particles are thought to be possible (at least not counted out yet) there are also a million other ways that intelligent forces can bypass naturally unbreakable laws such as wormhole's, however improbable they may be, given infinite time and flexible enough conditions anything is possible. so go ahead and become a theoretical physicist and prove this guy wrong.) This renders traveling to future quite unattractive: It is impossible to return from such a travel.

Asked in History of Science, Scientists, Louis Pasteur

Who was Louis Pasteur and what did he do?

User Avatar
Louis Pasteur was a 19th-century biochemist whose work with germs and microorganisms opened up whole new fields of scientific inquiry, aided industries ranging from wine to silk, and made him one of the world's most celebrated scientists. Louis Pasteur was born on 27 December 1822 in Dole, Jura, France. He was to become known as the founder of microbiology. Pasteur was the one who discovered the role of bacteria in fermentation. In 1857, through experimentation and research with bacteria, he determined that certain microorganisms contaminated fermenting beverages. He used this knowledge to develop a process whereby liquids such as milk were heated to kill all bacteria and moulds which were already contained within them. This process became known as pasteurisation. The first test of pasteurisation was completed by Pasteur with the assistance of Claude Bernard, on 20 April 1862. Pasteur then recognised that infectious diseases are caused by microorganisms, and his 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. The rabies vaccine was first tested on a nine-year-old boy named Joseph Meister, on 6 July 1885. Meister was bitten by a rabid dog, and was subsequently treated by Pasteur with a rabies virus he had grown in rabbits but weakened by drying, a treatment he had earlier tried on dogs. The treatment was successful and the boy survived without ever developing rabies. Joseph Meister later went on to become a caretaker at the Pasteur Institute. Pasteur was subject to strokes from the early age of 46, and eventually died in 1895 from complications resulting from these strokes.
Asked in Colonial America, Microbiology, Freemasons, Scientists, Louis Pasteur

Was Louis Pasteur a Freemason?

User Avatar
Louis Pasteur was most likely never a Freemason. He is not listed in William R. Denslow's definitive book, 10,000 Famous Freemasons, or by any other reputable source. Understand that, in most cases, it is virtually impossible to prove a negative, therefore one cannot say with absolute certainty that Pasteur was NOT a Freemason, but there is no evidence to indicate that he was. Masonry, like most groups, is very proud of its famous members and usually points them out, so if evidence existed, Pasteur would be claimed as a member by the Fraternity. When only anti-masons are the ones claiming someone was a Mason, it is very unlikely that the person really was. Despite what some say, Freemasonry simply isn't a "secret society" and there are generally plenty of membership records to be found.
