What Is the History of Physics?

He wasn't really a scientist in terms of direct science, but he was always astronomy. His mind thought in the way that a scientist's mind does, you know. A famous quote from him is, he who loves practice without theory is like a sailor with no rudder. The sun'm pretty sure, i read, definitely mon inthe ground, that the galactic age of our sun is 18 years. It went around the galaxy 18 times. But at that time at least, he supported a model where the sun was in the centre. Again, very controversial for its current time.
