Arlo U. Landolt

Da Wikipedia, l'enciclopedia libera.

Arlo U. Landolt (1935) è un astronomo statunitense.

Ottenuto il titolo di Doctor of Philosophy nel 1962 presso l'Università dell'Indiana, Landolt si è occupato principalmente di fotometria pubblicando un gran numero di liste, oggi molto utilizzate,[1][2][3] di stelle standard.[4][5] Ricevette nel 1995 il Premio George van Biesbroeck da parte dell'American Astronomical Society.[6]

Landolt fu lo scopritore di una particolare classe di nane bianche, le nane bianche pulsanti, quando osservò tra il 1965 e il 1966 che la luminosità di HL Tau 76 variava con un periodo di circa 12,5 minuti.[7]

A lui è stato dedicato l'asteroide 15072 Landolt.[5]

Lettris

Lettris is a curious tetris-clone game where all the bricks have the same square shape but different content. Each square carries a letter. To make squares disappear and save space for other squares you have to assemble English words (left, right, up, down) from the falling squares.

boggle

Boggle gives you 3 minutes to find as many words (3 letters or more) as you can in a grid of 16 letters. You can also try the grid of 16 letters. Letters must be adjacent and longer words score better. See if you can get into the grid Hall of Fame !
