Indirect measurement method of Thales to determine height vid
The crisis was the refutation of the metaphysical theory of the relation of the macrocosm to the microcosm by the collapse and growth of isosceles right triangles because not all magnitudes, which are numbers, are expressible as numbers based on the unit measure; therefore, the proposed growth happens in discrete, numerically inexpressible magnitudes rather than continuous magnitudes, and Pythagorean number theory is inadequate to regain continuity.
Whenever the height and shadow of an object are equal and they both measure as whole numbers, no number can be found for the hypotenuse, neither whole nor a ratio between whole numbers. This problem would have continued to crop up in further reflection on the isosceles right triangle within the Pythagorean community, and it would have inspired intellectually curious persons, such as Pythagoras and the Pythagoreans, to examine it further.
So as Cales points out the Odd and Even numbers were originally Asymmetric and Symmetric geometry using pebbles!
Alain Connes: The Music of Shapes - new upload vid
Title: The Music of Shapes Abstract: Quantum physics, especially matrix mechanics, has had a profound influence on mathematical notions of geometric space. This lecture will explain this link by dealing, among other things, with «spectra» and «the music of shapes». Indeed, if the geometrical characteristics of an instrument, for example, determine the sounds it can produce, then conversely, knowledge of the scale and chords produced by an object is sufficient to reconstruct its shape. This property makes it possible to characterize geometrical shapes from invariants that do not refer to a coordinate system. The resulting new geometry, illustrating the mathematical link between visual and auditory perception, has a wealth of applications in physics, in particular for gravitation and quantum physics. This lecture will also be an opportunity to discuss the meaning of the notions of variability and the emergence of time.
