Scientific Method

The scientific method is the basis of scientific investigation. A scientist will pose a question and formulate a hypothesis as a potential explanation or answer to the question. The hypothesis will be tested through a series of experiments. The results of the experiments will either prove or disprove the hypothesis. This category should contain questions and answers regarding the scientific method.

What was the effect of the condemnations of 1210-1277?

The Condemnations of 1210 to 1277 allowed scientists to pursue science empirically.

With the beginnings of the university system, standards on education were introduced to Europe. This happened in the 11th and 12th centuries.

In the 12th century, texts of ancient and medieval scientific words were translated into Latin and made available. These included both ancient Greek texts and Arabic. For whatever reason, the universities and their professors decided that they were going to teach strict conformance to Aristotelian science.

The implications of strict Aristotelian science included a halt to scientific advancement beyond what Aristotle knew, and that Aristotle was infallible. The second of these was found unacceptable by the Church, which began investigating into what to do about the situation.

The Condemnations of 1210 to 1277 condemned the teaching that Aristotle was infallible. This freed scientists to go beyond Aristotle. There are historians who believe this was the beginning of modern science.

Can you use PTFE to avoid friction in between 2 blocks when running coated material through blocks?

Maybe.
Any lubricant that doesn't react with the surface coating will work between the blocks. Dry lubricants (soaps, graphite, waxes...etc.) or wet lubricants (oil, glycerine, water, soaps...etc.) work well to varying degrees depending on the materials they lubricate and whether the lubricant and the surfaces react adversely under heat and pressure. Consulting a lubrication specialist, (most lubricant manufacturers consult with customers for the best match), for your best results. PTFE can breakdown under high pressure and high temperatures and usually is not great for high speed high temperature operations but works great at low speed and/or low pressure applications, and it does not react adversely with most materials.

Want is the aim of hookes law?

Hooke's law was designed to determine the restoring force of a spring, given its spring constant and the displacement of the spring from its equilibrium position. The law is written as follows:

F = -kx;

in which "F" is the restoring force, "k" is the spring constant, and "x" is the spring's displacement.

Why might people be taking the idea of sending viruses into space seriously?

Ask the Native American population about the smallpox virus. We would not want to bring along diseases (viral, fungal, bacterial, etc) that might be able to attack native life should we encounter it.

Also, it complicates the search for life if we introduce contamination--i.e. we send a probe to Mars, return some samples with complex organic molecules, and cannot determine whether it is life from Mars or contamination.

Who invented the Karvonen method?

The Karvonen method was founded by Finnish scientist Dr. M. J. Karvonen in 1957. The method deals with the heart rate reserve and the desired heart rate to burn calories.

Why is there a need to analyze data?

There is no point in collecting data simply for the sake of collecting data. You need to analyse it: summarise it and use key information from it to make some assessments about the data.

What does a hypothesis become after it is tested and proven?

A hypothesis, or group of hypotheses, that is accepted as consistently valid is a theory. Either a hypothesis or a theory can be ultimately disproven. One definition of a theory is an accepted hypothesis.
