Aristotle Was About Quantity, Not Quality, of Thought
I don't doubt that Aristotle thought more in actual footage during his life than any other person ever thought in the same elapsed time of sixty-two years. I do say, however, that any prize he deserves for so doing should be for quantity, not quality, as a great deal of it was spinach. He would sit around and think like one possessed, or he would walk around and think, since he was a Peripatetic, as they called it in those days. And then he would announce that Swallows spend the winter under ... 1

Gedankenexperiment
However, the subject need not be an esoteric one for a gedankenexperiment to be fruitful. My own favorite is Galileo’s proof that, contrary to Aristotle’s view, objects of different mass fall in a vacuum with the same acceleration. One might think that a real experiment needs to be conducted to test that hypothesis, but Galileo simply asked us to consider a large and a small stone tied together by a very light string. If Aristotle was right, the large stone should speed up the smaller one...Folksonomies: thought experiment testability

1 Gino Segre on the importance and validity of "thought-experiments," using Galileo's disproof of objects falling at different rates as an example.

Anagnorises and Peripetia
OK, I'm still in "Poetics," in Aristotle, and I'm thinking -- out of nowhere, two terms come crashing into my head that I haven't heard since my classics professor in college drilled them there. And they are anagnorisis and peripeteia. Anagnorisis and peripeteia. Anagnorisis is the Greek word for discovery. Literally, the transition from ignorance to knowledge is anagnorisis. It's what our network does; it's what "Dirty Jobs" is. And I'm up to my neck in anagnorises every single day. Great. T...Two flavors of the concept of discovery.

Galileo and the Altar Lamp Pendulum
IN 1583 Galileo Galilei (1564–1642), a youth of nineteen attending prayers in the baptistery of the Cathedral of Pisa, was, according to tradition, distracted by the swinging of the altar lamp. No matter how wide the swing of the lamp, it seemed that the time it took the lamp to move from one end to the other was the same. Of course Galileo had no watch, but he checked the intervals of the swing by his own pulse. This curious everyday puzzle, he said, enticed him away from the study of medi... 1 notes

The Glory of the Library of Alexandria
Alexander had already devoted considerable sums to finance the enquiries of Aristotle, but Ptolemy I was the first person to make a permanent endowment of science. He set up a foundation in Alexandria which was formerly dedicated to the Muses, the Museum {151}of Alexandria. For two or three generations the scientific work done at Alexandria was extraordinarily good. Euclid, Eratosthenes who measured the size of the earth and came within fifty miles of its true diameter, Apollonius who wrote o... 1 notes

Aristotle as the First Scientist
Aristotle repeatedly pointed out that his predecessors' work and conclusions were often marred by insufficient observation. He himself, after a remarkable analysis of the reproduction of bees, states that he cannot arrive at certain conclusions because "the facts have not yet been sufficiently ascertained. And if at any future time they are ascertained, then credence must be given to the direct evidence rather than to the theories; and to the theories also, provided that the results which the... 1 notes
notesClassification of animals, empirical observations... he got much wrong, but to call into question his achievements for this is like criticizing the invention of Calculus because Newton believed in magic.

Words are Money of Fools, but Nature Does Not Lie
For between true Science, and erroneous Doctrines, Ignorance is in the middle. Naturall sense and imagination, are not subject to absurdity. Nature it selfe cannot erre: and as men abound in copiousnesses of language; so they become more wise, or more mad than ordinary. Nor is it possible without Letters for any man to become either excellently wise, or (unless his memory be hurt by disease, or ill constitution of organs) excellently foolish. For words are wise men's counters, they do but rec... 1 notes

Muslim Science, European Science
The strangest thing of all is that our ulama these days have divided science into two parts. One they call Muslim science, and one European science. Because of this they forbid others to teach some of the useful sciences. They have not understood that science is that noble thing that has no connection with any nation, and is not distinguished by anything but itself. Rather, everything that is known is known by science, and every nation that becomes renowned becomes renowned through science. M... 1 notes

Ancient Observation of the Changing Landscape
So it is clear, since there will be no end to time and the world is eternal, that neither the Tanais nor the Nile has always been flowing, but that the region whence they flow was once dry; for their action has an end, but time does not. And this will be equally true of all other rivers. But if rivers come into existence and perish and the same parts of the earth were not always moist, the sea must needs change correspondingly. And if the sea is always advancing in one place and receding in a... 1 notes
notesFrom Aristotle's "Meteorology". He sees that rivers dry and flow and move.

An Experiment in Evaporation and Condensation finds Eleme...
Salt water when it turns into vapour becomes sweet, and the vapour does not form salt water when it condenses again. This I know by experiment. The same thing is true in every case of the kind: wine and all fluids that evaporate and condense back into a liquid state become water. They all are water modified by a certain admixture, the nature of which determines their flavour. 1 notes
notesFrom Aristotle's "Meteorology". An example of knowing something from experiment.
