Computers and computing have changed a lot over the History of Science but ESPECIALLY over the last 100 years. In this episode of Crash Course History of Science, we have a look at that history around World War Two and how that conflict...

The history of science up until the Cold War is often overshadowed by the Manhattan Project. But, today we are going to talk about advances in biomedicine, or healthcare based on a biological understanding of human bodies and diseases.

Scientists tend to be careful and resistant to big claims. So evidence for the possible end of the living world took a while to be seen as such. In this episode of Crash Course History of Science, Hank talks to us about where Climate...

It's time to heat things up! LITERALLY! It's time for Hank to talk about the history of Thermodynamics!!! It's messy and there are a lot of people who came up with some ideas that worked and other that didn't and then some ideas that...

The Presocratics: Crash Course History of Science #2

In this episode of Crash Course History of Science, we travel to the Americas to ask the question, "When are we?" and get some answers. We'll look at the Maya, Inca, and Olmec civilizations and how they recorded their science.

It's the final episode of our History of Science series and we thought it would be good to talk a little about some of the people we couldn't get to and some of the reasons we need to talk about diversity in scientists. Thanks for the...

You probably know some of the signs of industrialization in the nineteenth century: Trains connected cities, symbolizing progress. But they also brought about the destruction of rural lands, divisions between social classes, and rapid...

It's all about the SUPER TINY in this episode of Crash Course: History of Science. In it, Hank Green talks about germ theory, John Snow (the other one), pasteurization, and why following our senses isn't always the worst idea.

We’ve talked a lot about advances in biotech. But none of those could have happened without advances in computing. It’s time to get back to data and explore the unlikely birth, strange life, and potential futures of the Internet. In this...

Like Egypt, Sumer, and Mesoamerica, ancient China represents a hydraulic civilization—one that maintained its population by diverting rivers to aid in irrigation—and one that developed writing thousands of years ago. Today, we’re going...

Over the last four episodes, we’ve examined some of the stories that make up the idea of a “revolution” in knowledge-making in Europe. But we can’t understand this idea fully, without unpacking another one—the so called Age of...

For as long as Hank has hosted Crash Course, he's wanted to host a series about the history of science. We've been asking big questions for a really long time and we've all wanted to explore how we've sought to answer those questions...

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...

Sometimes trail blazers of science aren't famous like Darwin or Pasteur. Sometimes they're humble Abbots, just growing peas in the back of their Abbey. This is the story of Gregor Mendel and how his work was done, lost, then found again.

It's time to have a look at the future of human life and how technology could possibly extend longevity. But, within that tech, are questions of ethics that are not always at the top of mind when the tech is being developed. In this...

In fantasy stories, charlatans in fancy robes promise to turn lead into gold. But real alchemists weren’t just mystical misers. They were skilled experimentalists, backed by theories of matter.

And they played a huge role in the...

The study of electricity goes all the way back to antiquity. But, by the time electricity started to become more well known, a few familiar names started to appear. Edison, Galvani, and a few others really changed the way the world worked.

You might have recognized the names of some of the Greek natural philosophers. They were individuals with quirky theories, and we have records about them. But they weren’t the only people making knowledge back in the day. Today, Hank...

It's time to talk about one of the most awesome scientists that has ever been awesome: Marie Curie. She figured out ways to get an amazing education despite the limitations of her homeland, discovered some really important answers to the...

Until roughly 1100, there were relatively few places of knowledge-making. Monasteries and abbeys had special rooms called scriptoria where monks copied manuscripts by hand. But the biggest places where knowledge was made were the Gothic...

The religion of Islam significantly influenced knowledge-making in the greater Mediterranean and western Asian world. Islamicate scholars—meaning people influenced by Islamic civilization, regardless of their religious views—gave us...

Squeaks and Mister Brown pretend to go back in time to learn more about Trilobites, using special clues from fossils!

Money. We all use it. But is it real? I mean, you can touch a coin or bill, but who decided that’s worth anything? And what about all those 1’s and 0’s getting swapped and traded by computers thousands of times per second? How are those...
