I just learned abt a few of them.. (I’m in GRD 7)
Ptolemy was a geographer and astronomer and he made the best maps of his time. He also said that the earth is the centre of the universe and the sun and other planets revolve around it.
Nicolaus copernicus thought abt what potolemy said and his theory was that if this was true the planets pattern would be very complex, he concluded that the sun is the centre of the universe and the other planets revolved around it on circular orbits.
Galileo Galilei had invented a better version of a telescope and he invented a basic thermometer.
(Sry I’m not sure abt the other person. Sry if I’m late and I might have wrong sentence structure in some places. Hope this helps.)
