The biggest gap in science: complexity

Science with Sabine ·

2023/12/17

Everyone loves to talk about complex problems and complex systems, but no one has any idea what it means. I think that understanding complexity is THE biggest gap in science today. What do we even mean by complexity? What do we know about it? And what’s the problem with trying to explain it? That’s what we’ll talk about in this video. This episode comes with a quiz which you can take here.

These scientists got sued for doing their job

Science with Sabine ·

2023/12/17

Science and the law come in to conflict more often than you might think. In this episode I want to tell you about several cases that I have followed which have concerned me greatly. The issue here isn't the actual scientific evidence, it is rather the way that scientists pursue and discuss this evidence, usually in a straight-forward and frank manner that doesn't sit well with courts. Please feel free to support Data Colada's legal defense here. This episode comes with a quiz which

Is Science Dying?

Science with Sabine ·

2023/11/22

Is science coming to an end? On the one hand, it seems like scientific progress has slowed to a crawl and no big breakthroughs are happening any more. On the other hand, we are left with many unsolved problems in science that I am pretty sure have a solution. In this episode, I explain why I think that we need to seriously consider the possibility that we live in the final phase of scientific discovery.

Is time travel possible?

Science with Sabine ·

2023/10/15

What does physics say about time travel? Surprisingly enough it doesn't just say it's impossible, it's more complicated than that. In this video I'll sort out what Einstein's general relativity and quantum mechanics tell us about time travel. And is MIT really building a time machine to find dark matter? We'll get to that. This video has a quiz which you can take here.
