posted by Suzie Chhouk We know that our atmosphere is mainly nitrogen and oxygen. Nitrogen gas is quite inert, and oxygen - well, that's good for us and the animals, isn't it? Sometimes though, it's worth taking a closer look at the minority that make up the air we breathe, like aerosol particles. from TEDEd posted by Suzie Chhouk Air is so ubiquitous and yet (if we haven't polluted it too much) so invisible. Have you ever considered air to even have weight? I guess it is true what they say: out of sight, out of mind. Not so for everyone, though. Thanks to scientists who have studied gasses and our atmosphere, we can tell you how heavy is air. from TEDEd; lesson by Dan Quinn, animation by Sandro Katamashvili. posted by Suzie Chhouk In the laboratory, we often concern ourselves with the concentrations of our solutions. In nature, you can think of the ocean as one huge solution of varying heat and salt concentrations. These differences account for the creation of waves - and of course, the beautiful sounds and surf time that come with. Lesson by Sasha Wright, animation by Andrew Foerster. posted by Suzie Chhouk We - as a global community - have been arguing for quite some time about how to deal with the energy crisis. And we have had solar energy technology for some time now. Why haven't we just completely converted to solar energy? It seems to be the greenest option, doesn't it? The sun surely isn't going to burn out for billions of years... So what's the hold up? Addison Anderson explains as the narrator in the video below. Lesson by Alexandros George Charalambides, animation by Ace & Son Moving Picture Co., LLC. posted by Suzie Chhouk Did you survive the typhoon that just passed? Wonder if it's going to rain today? Well, try trusting your nose! Your nose knows! from It's Okay to be Smart. posted by Suzie Chhouk Admit it - quantum mechanics confuses you. But don't worry! You are far from alone. And, you have several fellow scientists who have a somewhat better grasp of the concept to help you along. Now you may ask, "What on earth does quantum mechanics have to do with global warming?" The quantum world is so very tiny we often forget how it affects our relatively macro world. Educator Chad Orzel is here to remind you how. Lesson by Chad Orzel, animation by Joana Bartolomeu (from TEDEd) posted by Suzie Chhouk What do quartz crystals, sand, and the glass in your window have in common? They are all compounds of silicon and oxygen - in different arrangements. But how can something so solid be so invisible? Learn more in the TEDEd video by Mark Miodownik and the answer to why aren't more things transparent? (English subtitles available) posted by Suzie Chhouk Did you know hundreds of mysterious engraved trails have been stumbled upon at the Racetrack Playa of Death Valley in California. There’s almost always a rock sitting at the end of the track, but no one has actually seen a rock -- not a pebble nor a boulder -- sliding on this nearly flat, dry mud surface. What gives? ...Keep reading to learn what the scientists discovered at IFLScience!
Turns out rocks are not the most boring science ever! posted by Suzie Chhouk This episode of SciShow news explores some exotic chemistry - the world's oldest water source and the rarest element. Hint: the former is approximately 1.5 billion years old and can potentially support life, and the latter can potentially be used to vaporize cancer! |
