25 Awe-Inspiring Science Talks on TED The natural world is an amazing thing, and despite the volumes upon volumes that we know about it, we’ve barely scratched the surface when it comes to truly understanding our universe and the things within it. Yet just because there’s so much information out there doesn’t mean you shouldn’t try to learn as much as you can about science. These lectures reflect information that’s at the cutting edge, from medical discoveries that could change lives to astrophysical research that’s expanding our knowledge of the worlds that lie beyond our own galaxy, and they can help you get an education in some of the greatest wonders the scientific fields have to offer. Humans These lectures address the science of human life, from how our brains work to how we interact with one another. Technology The latest technology and the speed with which it is evolving is nearly always awe-inspiring. Space Nature Health and Medicine

Preschool science activities How to nurture your child's interest in the natural world © 2008 -2012 Gwen Dewar, Ph.D., all rights reserved Can we design better preschool science activities? Activities that stimulate curiosity, teach science concepts, and avoid overwhelming or boring children with lessons that are developmentally inappropriate? In the article below, I review the advice of educational and cognitive psychologists about preschool science education. But if you are looking for specific activities, you can also check out these links: Floating and Boating is a set of science activities that encourage kids to play in the water, explore the concept of buoyancy, and make some cool contraptions. Dirt Lab is a set of activities that encourages kids to investigate the properties of dirt and mud. Animal tracking offers young children opportunities to exercise their spatial and scientific reasoning skills. Experiments with ice cubes introduce kids to aspects of the scientific method, as does this • how living things move
The History of Pretty Much Everything : Starts With A Bang “Listen; there’s a hell of a good universe next door: let’s go.” -e. e. cummings Sometimes, you just need to take stock of what we know, and appreciate how far we’ve come. A hundred years ago, we thought the Universe consisted of the stars and nebulae in our Milky Way. We thought Newton’s Law of Gravity governed it all, and that the other forces — electromagnetism and a few weird quantum things — were all there was. So why not — all in one article — go through the entire history of the Universe, from as early as we can say anything sensible to as late as we can say anything sensible? The first 10-25 seconds (or possibly even less): the Universe inflates. Image credit: Ned Wright. …and stretches it flat! …and stretches it across the whole sky, for hundreds of billions of light years! Inflation ends! 10-5 seconds: we can form stable protons and neutrons! What about anti-protons and anti-neutrons, you ask? 3 or 4 minutes: the Universe fuses protons and neutrons together into atomic nuclei!
How Browsers Work: Behind the Scenes of Modern Web Browsers Web browsers are the most widely used software. In this primer, I will explain how they work behind the scenes. We will see what happens when you type google.com in the address bar until you see the Google page on the browser screen. The browsers we will talk about There are five major browsers used on desktop today: Chrome, Internet Explorer, Firefox, Safari and Opera.

3D Solar System Web Sciences : Hubble révèle un nouveau type de planète Située à 40 années lumière de la Terre, l'exoplanète GJ1214b est composée essentiellement d'eau. De l'eau dans tous ses états! Découverte en 2009 grâce au télescope spatial Hubble, l'exoplanète GJ1214b, située à seulement 40 années lumière de la Terre, ressemble à une immense piscine, un waterworld disent les Anglo-saxons. Mais il ne ferait pas bon s'y baigner… Dans une étude à paraître dans la revue Astrophysical Journal , l'astronome Zachory Berta, du centre d'astrophysique de Harvard, aux États-Unis, révèle en effet que la température qui règne à la surface de ce nouveau monde serait de 232° C. Une atmosphère épaisse et humide Ces conditions extrêmes s'expliquent par la proximité de GJ1214b par rapport à son étoile: à peine 2 millions de km, soit 70 fois moins que la distance entre la Terre et le Soleil.
