Copernicus and Galileo: A Scientific Revolution

Copernicus and Galileo were major figures in the Scientific Revolution and were instrumental in transforming scientific thought regarding the cosmos from geocentrism to heliocentrism.

I'm nearly a year removed from high school and your videos are still amazing to watch. Thank you Tom for keeping interested in history.

I like that Tom gives shout outs to people, it's nice and makes it seem like he likes his fans and students!

I’d wish I had a teacher like you Tom when I went to school. You make things come alive. Thanks 🤩

[liamduffy]

I am one of Jenessa Friends!!!
Thanks Tom :)
You got us through the first month of Ap Euro while our teacher was gone so I justed wanted to say thanks and love the accent.

I’m at 2:51 into this video and I LOVE that I discovered your channel. Thanks. You’re discussing so much of my favorite stuff all at once. Wish we were friends.

I love the path you explained. The connecting dots is great part of your blogs. The way how you do it is great too.

Fascinating information given very clearly. As someone else has pointed out here, in science, the term "theory" is used for beliefs regarded as having been proven, and the term hypothesis is used for beliefs which have not been proven.

At 10:30, did you mean "it revolving around the SUN just like we are"?

i love that part when he showed the look alike photo of lord Farquaad confirmed in 5:16

[susans]

Ive found the motivation and will to study bc of your vids, bc i know how to start studying for the AP. THANK YOU.

[littleflower]

Your videos are great! I learn alot and you explain things in simple, everyday language. Appreciate your sense of humor too!

Hi Tom - great lecture. At 10:35 while you’re talking about the phases of Venus. you state Venus revolves around the earth. You meant ‘sun’.

5:17 - reasons I love watching these E-lectures... also, exam in one week

Thanks to you I got an A in Western Civilization I in college! Thank you, sir!

In science, something can be both a fact and a theory. Things like Gravity and evolution are both facts and theories for example.

[pietaval]

I always enjoy your analyses and watch your videos often. Thank you.

Hreat Video, Tom. the Renaissance was always the most Fascinating period of European history, to me at least.

[TehCthulhu]

Man, I have no idea how you could mention Johannes Kepler without bringing up Tycho Brahe, he's just too much fun to talk about.

I also think it's worth mentioning Ptolemy didn't create the geocentric model, but was the first to create a mathematical system to explain it. However, I realize talking about epicycles, deferents, and parsimony in science may be beyond the scope of this video.

Great work. Thanks for helping the laymen.

Just as a point of order, you are using scientific 'theory' and 'fact' incorrectly. Theories are buttressed by facts. A theory represents the highest level of certainty possible in the natural sciences. Gravity, germ theory of disease, planetary motion, evolution etc are all 'theories' backed by an often astounding number of facts.

I don't mean to be pedantic but this is a common misunderstanding that is often referenced by anti-science or pseudoscientific people (ie young earth creationists). These people often argue that 'theories' like evolution or climate change are essentially guesses. A scientific concept achieves the status of theory when it allows a falsifiable, predictive, explicative framework.

Great videos! Keep up the good work!
