Electronic music facilitates the use of any kind of microtonal tuning, and sidesteps the need to develop new notational systems. [21] In 1954, Karlheinz Stockhausen built his electronic Studie II on an 81-step scale starting from 100 Hz with the interval of 5 1/25 between steps, [ 91 ] and in Gesang der Jünglinge (1955–56) he used various ...
White's law states that the measure by which to judge the relative degree of evolvedness of culture was the amount of energy it could capture (energy consumption). White differentiates between five stages of human development. In the first, people use energy of their own muscles. In the second, they use the energy of domesticated animals. In ...
The earliest use I have found so far of the word "microtone" is in 1912 (two years before the earliest citation in the OED), but the article disparages the "widespread use" of the word. This suggests that, amongst ethnomusicologists at least, by 1912 "microtonal" and/or "microtonality" had already been in use for some time.
Wilhelm His Sr. (9 July 1831 – 1 May 1904) was a Swiss anatomist and professor who invented the microtome.By treating animal tissue with acids and salts to harden it and then slicing it very thinly with the microtome, scientists were able to further study the organization and function of tissues and cells under a microscope.
12-tone equal temperament chromatic scale on C, one full octave ascending, notated only with sharps. Play ascending and descending ⓘ. 12 equal temperament (12-ET) [a] is the musical system that divides the octave into 12 parts, all of which are equally tempered (equally spaced) on a logarithmic scale, with a ratio equal to the 12th root of 2 (≈ 1.05946).
The development of the nervous system in humans, or neural development, or neurodevelopment involves the studies of embryology, developmental biology, and neuroscience. These describe the cellular and molecular mechanisms by which the complex nervous system forms in humans, develops during prenatal development , and continues to develop ...
Human brain and skull. The ten-percent-of-the-brain myth or ninety-percent-of-the-brain myth states that humans generally use only one-tenth (or some other small fraction) of their brains. It has been misattributed to many famous scientists and historical figures, notably Albert Einstein. [1]
Organ culture is the cultivation of either whole organs or parts of organs in vitro. [1] It is a development from tissue culture methods of research, as the use of the actual in vitro organ itself allows for more accurate modelling of the functions of an organ in various states and conditions.
