Representation of an HDR Image,, and Beethoven (1770–1827) seem to possess almost superhuman powers. In literature, we have Shakespeare (1564–1616), Milton (1608–1674), Goethe (1749–1832), and several others. In mathematics, Archimedes (287–212 B.C.), Newton (1642–1727), and Gauss are ranked at the top, but magnificent contributi作者: Tonometry 時間: 2025-3-22 01:44 作者: tympanometry 時間: 2025-3-22 05:03 作者: conscience 時間: 2025-3-22 09:14
