Paul Andersen explains how to use mathematics appropriately. He begins by emphasizing the important role that mathematics plays in the life sciences today and in that the future. He describes important mathematical equations in each of...

THIS IS A RE-POST OF SCISHOW NEWS, WITH PHOTOGRAPHS! SORRY TO ALL THOSE WHO WATCHED IT WITHOUT THEM.

Scientists around the world discover about 18,000 new species every year. Each new organism has not only to be found, but also...

Armed with a sense of humor and laypeople's terms, Nobel winner Murray Gell-Mann drops some knowledge on TEDsters about particle physics, asking questions like, Are elegant equations more likely to be right than inelegant ones?

Isaac Newton's Universal Law of Gravitation tells us that there is a singularity to be found within a black hole, but scientists and mathematicians have found a number of issues with Newton's equations. They don't always accurately...

The Kepler mission has determined that terrestrial planets are extremely common, and may orbit most stars in the Milky Way. But these planets are difficult to directly image because they're dense and small. Our Sun is about ten billion...

This week on Crash Course Literature, John Green is continuing to talk about Shakespeare's dark, bloody, Scottish play, Macbeth. This time around, we're looking at the play's characters operate, how the play deals with gender, and the...

Anthony and Squeaks are spending the day watching videos all about cats and dogs of all varieties and they’re learning all sorts of interesting things along the way!

The cross product is a way to multiple to vectors in 3d. This video shows how to visualize what it means.

Is the Universe Entirely Mathematical feat. Max Tegmark

Africa needs new energy sources to fuel its development, but the continent should invest in renewable energy instead of cheap, polluting alternatives like coal, says climate inclusion activist Chibeze Ezekiel. He tells the story of how...

Natural selection can lead to some pretty amazing adaptations, but sometimes the resulting traits aren’t the most efficient solutions to the problems at hand. With the bar set to “good enough,” here are some features that arose from...

For a long time, scientists considered the neocortex the brainiest part of the human brain – an obvious candidate for the thing that makes us unique. But in some ways, it’s not that different from other mammals’ brains. So researchers...

When it comes to fighting COVID-19, scientists are throwing every bit of science we’ve got at it. A creative technique some researchers are looking into involves using gene therapy to fight this virus with… another virus!

What is Pick's Theorem and how can we prove it?

As climate change accelerates, finding clean alternatives to fossil fuels is more urgent than ever. Social entrepreneur Vaitea Cowan believes green hydrogen is the answer. Watch as she shares her team's work mass producing electrolyzers...

Scientists were able to measure the emission lines of antimatter! And we may have some new clues about how dinosaurs lost their teeth on the way to becoming birds.

This video is about the original cold fusion: μ muon-catalyzed cold fusion of deuterium, tritium, hydrogen, into helium-3 and helium 4. The problems with it are the half-life of muons and the sticking of muons to alpha...

Some people try to attack things like evolution by natural selection and man-made climate change by saying "Oh, that's just a THEORY!" Yes, they are both theories. Stop saying it like it's a bad thing! It's time we learn the difference...

There are labs so silent that most people can't stand being inside them, but that stillness lets us run some of our most sensitive experiments.
