Stellar Spectra and That Famous Mnemonic,OBAFGKM, can be remembered with that famous mnemonic; ‘Oh Be A Fine Girl Kiss Me’. In fact every self-respecting astronomer should ask the question; ‘Why such an odd jumble of letters?Why not ABCD etc.?’ I myself can’t remember asking such questions—well it . a long time ago!作者: Cerumen 時間: 2025-3-22 19:54

When Is a Spectral Line Not a Spectral Line?,nes connected by less dark regions. A spectral line clearly isn’t just a simple infinitely narrow line; the answer to the question posed in the title of this chapter is— ‘when it is a .’.

Internalising Exile at Home and Away,attoo. It argues that diasporic or xeniteian Scots have the right to develop their own forms of Scottishness, which home-based communities have no right to question. It suggests that the search for Scottishness, as for any other national identity, is a response to a deep human need to ‘belong’ in the face of death’s certainty.作者: adjacent 時間: 2025-3-28 14:21
