Science as Observation and Experiment a. He asks the reader to carefully observe an eyeball, say that of an ox, from which a portion of the rear has been removed with sufficient care to leave the eyeball fluid untouched.

New data results in new theories, and theories inspire experiments which are designed to test them This cyclic process propels science forwards. Any new theory must displace an old one, and each new theory therefore needs abundant evidence in its favour.

No-one will abandon the standing theory without good reason. The Science of Mind and Behaviour 8 "with some chapters on science, and offers the following as two major steps in scientific theory: Theory Construction, "an attempt to explain observed phenomena".

Hypothesis Testing, involving "making specific predictions about behaviour under certain specified conditions". The best thing about theories is that when new evidence comes to light, new theories arise to replace or modify the old ones.

Russell explains how science starts with initial observations and continually builds until major theories are brought to general acceptance through long periods of practical trial and error. From a number of such facts a general rule is arrived at, of which, if it is true, the facts in questions are instances.

This rule is not positively asserted, but is accepted, to begin with, as a working hypothesis. If it is correct, certain hitherto unobserved phenomenon will take place in certain circumstances. If it is found that they do take place, that so far confirms the hypothesis; if they do not, the hypothesis must be discarded and a new one must be invented.

However many facts are found to fit the hypothesis, that does not make it certain, although in the end it may come to be thought of in a high degree probable; in that case, it is called a theory rather than a hypothesis. It can even be dangerous: If data leads a researcher to claim some radical new element of cause and effect, then, there has to be a valid underlying theoretical framework in addition to the data The lack of good theory can lead people far 'down the garden path', i.

A common criticism of the theories of evolution and of the big bang is that "they are only theories". However, they misunderstand what the word "theory" means. A scientific theory that explains the facts well is accepted; whereas one that doesn't is rejected.

That something "is only a theory" does not affect whether it is accurate or not. Some example theories include the theory of gravity, and the theory that the Earth orbits the Sun.

Clearly, the evidence is the important aspect of any theory! A theory must make it clear exactly what criteria would falsify it, and therefore, the theory must be testable Richard Dawkins defines all of science in terms of its testability: The academic Karl Popper, is often cited as being the source of this requirement and it has become one of the most well-known 'rules' of scientific methodology.

Karl Popper proclaimed the principal in Logik der Forschung inpublished in Vienna. Professor Victor Stenger points out that Popper and Rudolf Carnap explored the same idea, Carnap in "Testability and Meaning" in Philosophy of Science 13therefore it appears that Popper is given undue credence as the sole purveyor of the idea by academics.

However the science historian Patricia Fara states that Popper first voiced his falsification criteria as long ago as after observing a lecture by Einstein No matter the history, it is now a very well established principal.

This is because we have no way of knowing a priori that other, competing models might be found someday that lead to the same empirical consequences as the one tested.The Ultimate Burrito has all your nutrients from 9 whole ingredients in the most cost effective, time efficient, and environmentally friendly form.

Usually, this middle view accepts experimentation on some, but not all, animals and aims to avoid unnecessary use of animals in scientific research by pursuing alternatives to animal testing.

The following sections briefly outline a few of the arguments for and against animal experimentation. - Animal testing is the use of non-human animals for scientific experimentation.

[BINGSNIPMIX-3

There are estimates that 50 to million vertebrate animals worldwide from zebra fish to on-human primates are used annually. The "Scientific Method" is a set of steps taken to ensure that conclusions are reached sensibly, experiments designed carefully, data is interpreted in accordance with the results of tests, and that procedures can be verified independently.

Oct 23,  · Animal testing is the use of animals in biological, medical, and psychological studies. Human beings and many animals have similar organ systems and body processes. I originally introduced the term “orthorexia” in the article below, published in the October issue of Yoga Journal.

Some of the things I said in the article are no longer true of .
