Simple elegant laws like the Planck radiation formula agree with reality accurately over all the electromagnetic spectrum; on the other hand, the need for abstract mathematical concepts stemming from complexinsert 发表于 2025-4-1 08:17:26

He also tried to measure the speed of light and built the first astronomical telescope, becoming the founder of Modern Astronomy. HisSOW 发表于 2025-4-1 10:20:13

(However, the times were ripe and some of the works by Giordano Bruno (1548–1600) imply correct ideas about the relativity of motion.) The worst difficulty was that the 2000-
