Another potentially confusing problem is the naming of some of the tunings which may have misleading names, like the ruibin tuning. Ruibin is the name of the Chinese pitch which Western equivalent is "F♯", but that note does not appear or is used in the tuning, and so it is difficult to explain the logic in the naming.
An example of a fine-tuning problem considered by the scientific community to have a plausible "natural" solution is the cosmological flatness problem, which is solved if inflationary theory is correct: inflation forces the universe to become very flat, answering the question of why the universe is today observed to be flat to such a high degree.
In 1913, chemist Lawrence Joseph Henderson wrote The Fitness of the Environment, one of the first books to explore fine tuning in the universe. Henderson discusses the importance of water and the environment to living things, pointing out that life as it exists on Earth depends entirely on Earth's very specific environmental conditions, especially the prevalence and properties of water.
A system like Swich's, with all its major thirds more or less sharp, is confirmed by Friedrich Wilhelm Marpurg's description of the way Bach's famous student J.P. Kirnberger was taught to tune in his lessons with Bach: Kirnberger's tuning allows all 24 keys to be played through without changing tuning nor unpleasant intervals, but with varying ...
The Norton Commando is a British Norton-Villiers motorcycle with an OHV pre-unit parallel-twin engine, produced by the Norton Motorcycle company from 1967 until 1977. Initially having a nominal 750 cc displacement, actually 745 cc (45.5 cu in), in 1973 it became an 850 cc, actually 828 cc (50.5 cu in).
The three tuned circuits, controlled by the 3 large knobs, had to be tuned in unison to the new station. So tuning in a station was a process of successive approximation. Once a station was found, the numbers on the dials were written down, so it could be found again. Tuning all 3 stages of a TRF set in unison.

Pythagorean tuning is a system of musical tuning in which the frequency ratios of all intervals are determined by choosing a sequence of fifths [2] which are "pure" or perfect, with ratio :. This is chosen because it is the next harmonic of a vibrating string, after the octave (which is the ratio 2 : 1 {\displaystyle 2:1} ), and hence is the ...
