I’m really interested to know what you think about this clip from Noah. Half creation, half science lesson and very cool graphics.
I can imagine a few purists getting antsy about this but if you look at it as a tale or a legend it’s actually really cool!
I mean earth is no Krypton but maybe our story is just as cool!
Ever had an issue playing Playstation with a buddy and battled over who controls the main menu?
Now imagine playing that with 75 thousand others at a time. This is exactly happening over at Twitch Plays Pokemon. Players input their moves in the chat box on the left.
As you’ll see, anarchy reigns over democracy!
I wonder if the pit crew would be just as enthusiastic about changing the tyres on my Honda Civic. The Ferrari crew are in and out in just over two seconds. Talk about a well oiled machine!
Here’s another video from Mercedes AMG. Again in and out in about two seconds, this time from a bunch of different angles. This one goes on for about 5 minutes so a quick warning: If you’re watching this in a public place please turn down the volume! The mosquito-like buzz of the engine might get you squished too!
Beautiful New Zealand.
From this vantage point you can see all the way from my birthplace, Paraparaumu on the west coast of the North island, to Christchurch where I learnt all I know about Space, Astrophysics and the universe at the University of Canterbury
Commander Chris Hadfield spoke to the BBC about the beauty of New Zealand from this very vantage point:
" The wine country of the South Island, and the North end of New Zealand - it just looks so beautiful"
"After you’ve crossed New Zealand you have a long passage across the pacific… gosh, it takes almost half an hour to cross the pacific - so looking at New Zealand, it’s just beautiful."
Oh how I love this.
Turning down Cornell to instead choose Harvard - I think we all wish we could do that! I admire both Neil deGrasse Tyson and Carl Sagan for their immeasurable contribution to science communication. Only yesterday was I talking about these guys to my father as we gazed at the stars.
I can’t wait for Neil’s remake of Sagan’s Cosmos, which airs in the US March 9th.
The original belongs to the The Seth Macfarlane Collection of the Carl Sagan and Ann Druyan Archive at the Library of Congress. Macfarlane, famous for Family Guy, Ted and Oscars fame, is a long time cosmos fan producing the New Cosmos series.
How Do Batteries Work?
I had a request from an anon, so here goes. The first thing we need to know about batteries is that in essence what they’re doing is converting stored chemical energy into electrical energy. They do this by a series of reduction-oxidation reactions (redox). The first step involves the positively charged anode (anodes attract negatively charged ions called anions), at the anode electrons are moved from the electrolyte into the anode where they generate a voltage (which is a potential difference between energies at 2 points) and electromotive force. This is the oxidation step of the reaction. The electrolyte then converts into another compound or simply changes oxidation state. The electrons meanwhile go about their business and do whatever work they have to do before flowing into the cathode of the battery. At the cathode the corresponding reduction reaction occurs, quite separately to the oxidation component. Here electrons flow from the cathode into the second electrolyte which undergoes another chemical change. To complete the circuit some exchange of ions has to occur to make sure the flow continues, this is usually mediated by a salt bridge which connects the two electrolytes. Hope that helps!

Fluid dynamics appear at all kinds of scales.
The animation above shows two comets, Encke and ISON, on their recent approaches toward the sun.
The darker wisps emanating from the right side of the image are part of the solar wind, a plasma stream continuously emitted by the sun's upper atmosphere. Although the solar wind is very rarefied by terrestrial standards, its density is sufficient to whip the comets’ tails of gas and dust from side-to-side.
Scientists use images like these to learn more about the structure of the solar wind based on its interaction with the comets.

I Jake Louis Milne do solemly swear to waste the entirety of my designed study time to watching the pitch drop experiment. For science. Not procrastination.
Join me on the ninth watch here: http://www.theninthwatch.com
I said it’s not procrastination alright?!?
