Earth Science: Crash Course History of Science #20

It's Earth Science time!!!! In this field, natural philosophers were asking questions like, what’s up with fossils? Are they the remains of extinct organisms? Or are they so-called “sports of nature”—rocks that just happen to look like living things but don’t /mean/ anything? And most importantly, how old is… everything?

"The Earth Sciences are fascinating"


Yes, you guys should do a series.

I'm a 27 year old techie, science junky/music fanatic and this channel was the reason I fell in love with learning.

The pronunciation of "principia" really depends on which contextual and regional tradition of pronouncing Latin you decide to go with. In Classical Latin, the <c> was most certainly pronounced /k/, but by the time of Vulgar Latin the sound had become palatalised before front vowels. In Ecclesiastical Latin, for example, it's pronounced /t͡ʃ/ (as in the <ch> in English "chair"), which is also the pronunciation used in Italian and Romanian pronunciations of the letter in their respective traditions of New Latin, while English an French pronounce it as /s/, thus "prin/s/ipia" as opposed to "prin/k/ipia".

Neither pronunciation is more correct than the other, as long as it's consistent, e.g. if you use prin/s/ipia, following English New Latin, then the <æ> in "philosophiæ" should be pronounced /eɪ/ (as in the <ay> of "day"), but if you use prin/k/ipia, following Classical Latin, then <æ> should be pronounced /aɪ/ (as in "eye").

Does Earth Science rock?

... "Buddy you know it."

[RangerRuby]

Wow! History is so interesting and the History of a certain type of History is awesome! I love how Crash Course makes History and Science come to life!

Why no crash course Geology. The nearest is the physical geography part of the Geography crash course.

[becnal]

This is my favorite series on YouTube. Just fantastic.

Your portrait of Lyell is actually the young Charles Darwin.

[unleashingpotential-psycho]

That would be cool if Google Maps could also utilize geological maps.

Note to the Crash Course producers: Thanks for all you do. The playlist for this course does not include episodes 11 and 12. Could you check on that?

Thank you for mentioning the specific Native tribes that Couvier talked to by name!!! it's so important to recognize that Native America was not homogenous

[JohnBrockman]

THANK YOU

The Principia thing has been bugging me forever.

This is the first time I’m watching a recent video on this channel. I’ve really only watched the chemistry and physics videos. I’m in 9th grade and I’m learning Earth Science. This was helpful! Thank you!

[csagan-bhqy]

Why this channel is for free !! They pack enormous amount of knowledge in one place

[Brainstorm]

How old is everything? Is a great title for a book about questions kids ask, which turn out to be surprisingly difficult to answer.

[joryjones]

Earth, wind and Geology is my favorite ‘rock’ band.

I love the Charles Darwin and his Finch cameo by thought cafe before Buckland's portrait. That was so funny to see Darwin's thought cafe cameo.

I'm really curious how geologist determined the age of the earth. Now, my questions are answered. Many speculation and theories regarding the age of earth have arisen during 17th century in Europe, people do believe that the age of the earth is parallel with the age of humans. It is really awesome how geologist determined the age of the earth depending on the fossils, volcanoes, and rocks. Their conclusions and studies has a big impact in the history of science because it help us to determined the age of the earth.

[williamdragon]

You should make a series on the Earth Sciences.

You guys have helped me so much in college! I do wish your crash course kids would expand in some subjects my kids love watching, but could definitely use more videos in math and English. :)
