It’s perfectly human to grapple with questions, like ‘Where do we come from?’ and ‘How do I live a life of meaning?’ These existential questions are central to the five major world religions — and that’s not all that connects these faiths. John Bellaimey explains the intertwined histories and cultures of Hinduism, Judaism, Buddhism, Christianity and Islam.
No matter how you think of it, your skin is very important. It covers and protects everything inside your body. In humans, it is the largest organ of the integumentary system.
Graphene is the most promising new material out there, likely to revolutionize the way we do or build almost anything. It’s pure carbon, and totally amazing. Trace shows us all the different ways this material could change life on Earth.
Behrokh Khoshnevis is a professor of Industrial & Systems Engineering and is the Director of Manufacturing Engineering Graduate Program at the University of Southern California (USC). He is active in CAD/CAM, robotics and mechatronics related related research projects that include the development of novel Solid Free Form, or Rapid Prototyping, processes (Contour Crafting and SIS), […]
Ever wondered how honey is made? Here’s a really good explanation!
The energy in the universe never increases or decreases — but it does move around a lot. Energy can be potential (like a stretched-out rubber band waiting to snap) or kinetic (like the molecules that vibrate within any substance). And though we can’t exactly see it, every time we cook dinner or shiver on a cold night, we know it’s there. George Zaidan and Charles Morton get excited about energy.
Kids are able to heal from injuries so much faster than adults thanks in part to one particular protein. As Anthony shows us, scientists are showing remarkable progress in harnessing that protein into a powerful drug enabling the body to regrow lost tissue.
The mechanisms of evolution explained in one video.
Hashing Algorithms are used to ensure file authenticity, but how secure are they and why do they keep changing?
How do electric cars work? What is an electric car? Electric cars use electric motors to power the vehicle, rather than an internal combustion engine. The result is a vehicle that produces no emissions, requires little maintenance, and is extremely cheap to recharge. With advances in lithium ion batteries, electric cars are becoming more and more popular.
Pi, Spigot Algorithms and why The Simpsons is not in Base 8?
Everyone’s heard someone say that they’re “just not a math person.” But don’t believe them… it’s a lie! These people are just lazy and science proves it! Trace Dominguez explains.
Math is logical, functional and just … awesome. Mathemagician Arthur Benjamin explores hidden properties of that weird and wonderful set of numbers, the Fibonacci series. (And reminds you that mathematics can be inspiring, too!)
According to some scientists, we must begin using more nuclear power in order to prevent global warming from accelerating. But that creates a huge nuclear waste problem. But scientists at the University of Sheffield think they might have found a very unique way of handing it that could make nuclear waste a problem of the past.
Ever wondered what happens to your body if you don’t get enough water? Our bodies are mostly water by weight, so in today’s episode of SciShow Hank explains what happens to your body as it starts to shut down when you go without that tasty H2O.
