Dielectric - Wikipedia, the free encyclopedia: "A perfect dielectric is a material with zero electrical conductivity (cf. perfect conductor),[5] thus exhibiting only a displacement current; therefore it stores and returns electrical energy as if it were an ideal capacitor."

Differential structure - Wikipedia, the free encyclopedia
Differential structure - Wikipedia, the free encyclopedia: "Differential structures on spheres of dimension 1 to 20[edit]
The following table lists the number of smooth types of the topological m−sphere Sm for the values of the dimension m from 1 up to 20. Spheres with a smooth, i.e. C∞−differential structure not smoothly diffeomorphic to the usual one are known as exotic spheres.
Dimension 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
Smooth types 1 1 1 ? 1 1 28 2 8 6 992 1 3 2 16256 2 16 16 523264 24
It is not currently known how many smooth types the topological 4-sphere S4 has, except that there is at least one. There may be one, a finite number, or an infinite number. The claim that there is just one is known as the smooth Poincaré conjecture (see generalized Poincaré conjecture). Most mathematicians believe that this conjecture is false, i.e. that S4 has more than one smooth type. The problem is connected with the existence of more than one smooth type of the topological 4-disk (or 4-ball)."

Можно не услышать не то что мотор подъезжающего автомобиля, но и его сигнал.

При измерениях использовался программно-аппаратный комплекс RightMark™ Audio Analyzer PRO нашей разработки. Использовался измерительный стенд Brüel & Kjær 4153 - Artificial Ear/Ear Simulator (IEC 60318-1), Сделано в Дании, стоимость около 5000 евро. Измерения АЧХ приводятся в качестве справочных. Не стоит по ним угадывать звучание модели наушников! На АЧХ виден лишь диапазон частот и основные тенденции! Подъем АЧХ на НЧ у закрытых наушников сильно зависит от силы прижима чашки.
