Too often, people feel checked out of politics — even at the level of their own city. But urban activist Alessandra Orofino thinks that can change, using a mix of tech and old-fashioned human connection. Sharing examples from her...

Today we’re going to talk about data relationships and what we can learn from them. We’ll focus on correlation, which is a measure of how two variables move together, and we’ll also introduce some useful statistical terms you’ve probably...

It’s time for molecular analysis! On this episode of Crash Course Organic Chemistry, we’re learning about mass spectrometry and infrared spectroscopy through the lens of a forensic investigation. Put on your lab coats, and let’s solve...

In our final episode of Crash Course Geography we're going to take a look towards the future, and to do that we'll need to revisit our fundamental geography tools: space, place, and human-environment interactions! We'll talk about the...

Alkanes are kind of the wallflowers of organic chemistry, but they still have important functions in the world around us. In this episode of Crash Course Organic Chemistry we’re building our knowledge of organic molecules by learning all...

Over the course of this series, we've seen that outbreak science is actually MANY sciences, including biology, epidemiology, sociology, and even economics! Because outbreak science is an interdisciplinary field, everyone has a role to...

Feeling like the world is becoming less friendly? Social theorist Jonathan Zittrain begs to differ. The Internet, he suggests, is made up of millions of disinterested acts of kindness, curiosity and trust.

Scientists and Engineers spend over half of their working day reading, evaluating and producing text. Therefore it is important that we produce students that have a high level of scientific literacy. Students normally struggle with...

You're being watched. That sounded more sinister than I intended, but online, it's true. Facebook, Instagram, Amazon, Netflix... the list goes on and on. They're watching what you do, what you shop for, what you watch... all of it. And...

Paul Andersen describes pieces of evidence that Charles Darwin used to support the idea of evolution and his process of natural selection. He begins with the following evidence use in the Origin of Species; artificial selection,...

This week on SciShow news, strap in for a trip through the frontier of the human brain. The human connectome is a years long venture to explore and map the pathways of the human brain, and this past week scientists released two terabytes...

Oxidation-reduction reactions are going on around us, and inside us, all the time, and we can make redox reactions in organic chemistry easier to understand by tracking carbon-oxygen bonds. In this episode of Crash Course Organic...

Like a trendy dance, a fighting combo, or a secret handshake, organic reactions can be broken down into simpler steps. In this episode of Crash Course Organic Chemistry, we’ll specifically be looking at alkene addition reactions, and...

Today we're going to introduce bayesian statistics and discuss how this new approach to statistics has revolutionized the field from artificial intelligence and clinical trials to how your computer filters spam! We'll also discuss the...

The organic molecules that make up life on Earth are more than just the 2-D structures we’ve been drawing so far. Molecules have 3-D shapes that help us understand what they can do. In this episode of Crash Course Organic Chemistry,...

How do you talk to someone who doesn't believe in climate change? Not by rehashing the same data and facts we've been discussing for years, says climate scientist Katharine Hayhoe. In this inspiring, pragmatic talk, Hayhoe shows how the...

In this video Paul Andersen explains how scientific theories are created and modified over time. He starts by discussing the theory of natural selection as a model for the creation and modification of theories. He gives examples of...

Paul Andersen explains how graphs are used to visually display data that is collected in experimentation. He describes five main types of graphs; line graph, scatter plot, bar graph, histogram and pie chart. He describes the important...

Paul Andersen explains how mathematics and computational thinking can be used by scientists to represent variables and by engineers to improve design. He starts by explaining how mathematics is at the root of all sciences. He then...

First thing’s first: what is media literacy? In our first episode, Jay breaks this question down and explains how we’re going to use it to explore our media saturated world.

African artifacts shown in museums worldwide are often not borrowed, but stolen -- and TED Fellow Jim Chuchu is on a mission to get them back. Learn the sordid history behind how many of the collections in the West came to be, Chuchu's...

Today we’re going to talk about ethical data collection. From the Tuskegee syphilis experiments and Henrietta Lacks’ HeLa cells to the horrifying experiments performed at Nazi concentration camps, many strides have been made from...

In this video Paul Andersen explains the importance of scale in science and engineering. The Universe varies in size along three scales: size, timespan, and energy. Many phenomenon are too small and fast, or two large and slow to...
