The physics of surfing I TED-Ed

Published on Mar 11, 2019
Whether or not you realize it, surfers are masters of complicated physics. The science of surfing begins as soon as a board first hits the water. Surfers may not be thinking about weather patterns in the Pacific, tectonic geology or fluid mechanics, but the art of catching the perfect wave relies on all these things and more. Nick Pizzo dives into the gnarly physics that make surfing possible.

Paul Davies: "The Demon in the Machine" | Talks at Google

Published on Mar 8, 2019
Paul Davies is an English physicist, writer and broadcaster, a professor at Arizona State University as well as the Director of the Center for Fundamental Concepts in Science. His research spans fields like cosmology, quantum field theory, and astrobiology.
For Talks at Google he discusses his new book "The Demon in the Machine" about how hidden webs of information are solving the mysteries of life. For generations, scientists have struggled to make sense of the fundamental question "what is life?". On the boundary of science and philosophy, Paul Davies wonders if life can be explained by known physics and chemistry, or whether we do need something fundamentally new?

How you've been melting cheese WRONG your entire life - BBC

Published on Mar 5, 2019
Cherry Healey gets some scientific tips on making the best possible melted cheese! Is mozzarella – the traditional choice for pizzas -the scientific best bet? Cheddar? Blue cheese?
She finds that not all cheeses are equal, and that to melt well they must sit in a pH zone between 5 and 5.9. This explains why blue cheese and feta don’t work on pizza but mozzarella and gruyere do. Gregg Wallace and Cherry Healey get exclusive access to some of the largest factories in Britain to reveal the secrets behind production on an epic scale.

Gender equality in STEM is possible. These countries prove it I Big Think | Science: resources for South African teachers | Scoop.it

9 March 2019

Women have been responsible for some of the most important scientific breakthroughs that shaped the modern world, from Marie Curie's discoveries about radiation, to Grace Hopper's groundbreaking work on computer programming, and Barbara McClintock's pioneering approach to genetics. Globally, though, about 72 percent of scientific researchers are men. This trend, however, is turned upside down in countries such as Lithuania, Bulgaria, Portugal, and Denmark.
