All Models are Wrong, but some models are useful
As the statistician George E. P. Box wrote, “All models are wrong, but some models are useful.”90 What he meant by that is that all models are simplifications of the universe, as they must necessarily be. As another mathematician said, “The best model of a cat is a cat.”91 Everything else is leaving out some sort of detail. How pertinent that detail might be will depend on exactly what problem we’re trying to solve and on how precise an answer we require.
Nor are statistical models...All models are simplifications of the universe, this includes language as a form of modeling.

An Imaginary Diploma
The Johns Hopkins University certifies that John Wentworth Doe does not know anything but Biochemistry. Please pay no attention to any pronouncements he may make on any other subject, particularly when he joins with others of his kind to save the world from something or other. However, he worked hard for this degree and is potentially a most valuable citizen. Please treat him kindly.That gives a better understanding of the value of the scientist.

There is No Rule to New Knowledge
In no subject is there a rule, compliance with which will lead to new knowledge or better understanding. Skilful observations, ingenious ideas, cunning tricks, daring suggestions, laborious calculations, all these may be required to advance a subject. Occasionally the conventional approach in a subject has to be studiously followed; on other occasions it has to be ruthlessly disregarded. Which of these methods, or in what order they should be employed is generally unpredictable. Analogies dra...Folksonomies: knowledge exploration

The Birth of Immunology
I like to think that when Medawar and his colleagues showed that immunological tolerance could be produced experimentally the new immunology was born. This is a science which to me has far greater potentialities both for practical use in medicine and for the better understanding of living process than the classical immunochemistry which it is incorporating and superseding.Folksonomies: immunology

Is Beethoven's <em>Fifth Symphony</em> a meme, or only th...
Whether by coincidence or by memetic transmission, Beethoven is the favourite example for illustrating this problem. Brodie (1996) uses Beethoven's Fifth Symphony, Dawkins (1976) uses the Ninth and Dennett (1995) uses both the Fifth and the Seventh. Dennet adds that the first four notes of Beethoven's Fifth are a tremendously successful meme, replicating all by themselves in contexts in which Beethoven's works are quite unknown. So are they the meme, or the whole symphony?
If we cannot answe...We cannot specify the unit of a meme.
