Lyman, Ukraine
Lyman (, ), formerly Krasnyi Lyman (, 'Red Lyman') from 1925 to 2016, is a city in the Donetsk Oblast, Donetsk region of Ukraine.

The population was down from 28,172 in 2001. In October 2022, following the two Battles of Lyman of the 2022 Russian invasion of Ukraine, 2022 Russian Invasion of Ukraine, the population was estimated to be approximately 5,000.The Ukrainian authorities have yet to offer full estimates of the population loss in areas reclaimed in the offensives.

Lyman Series
In physics and chemistry, the Lyman series is a hydrogen spectral series of transitions and resulting ultraviolet emission lines of the hydrogen atom as an electron goes from ''n'' ≥ 2 to ''n'' = 1 (where ''n'' is the principal quantum number), the lowest energy level of the electron. The transitions are named sequentially by Greek letters: from ''n'' = 2 to ''n'' = 1 is called Lyman-alpha, 3 to 1 is Lyman-beta, 4 to 1 is Lyman-gamma, and so on. The series is named after its discoverer, Theodore Lyman. The greater the difference in the principal quantum numbers, the higher the energy of the electromagnetic emission. History The first line in the spectrum of the Lyman series was discovered in 1906 by Harvard physicist Theodore Lyman, who was studying the ultraviolet spectrum of electrically excited hydrogen gas. The rest of the lines of the spectrum (all in the ultraviolet) were discovered by Lyman from 1906-1914. The spectrum of radiation ...
