Sleep /sli:p/ noun A condition of body and mind which typically recurs for several hours every night, in which the nervous system is inactive, the eyes closed, the postural muscles relaxed, and consciousness practically suspended.(Google definition) Sleep. We spend a third of our lives doing it. But what actually is it and how can we make it even more beneficial?
I've been spending a lot of my limited free time on YouTube recently, and thought that instead of talking about what I've been watching, I should tell you about some of the awesome science channels that are on there (in no particular order).
1. Veritasium - this is a channel that tries to explain so many things about the world around us by showing us cool things. For example:
This explains what a kilogram actually is and how the definition is changing. Now I had never even thought about this before but found it incredibly interesting to watch!
2. Vsauce focuses more on mind blowing facts. This video completely blew my mind!
To think that we're all at least 50th cousins! Say what?!?!?
3. Crash Course - This channel is by the awesome John and Hank Green but is more to teach us about things than to make our minds explode.
This video may be a little bit on the controversial side for anyone who's religious, but I find this stuff very interesting, although Hank did use a bit too many long words!
4. Sci Show - Yes, another channel from the Green brothers, this time focusing more on science news.
Now Blogger has decided to stop embedding videos, so here's the link to a video about why we lie - https://www.youtube.com/watch?v=MX3Hu8loXTE&list=TLMW6oE4I-1m_n7IyNkSrmOSaAFRcusjXZ.
As you can see, there are so many different aspects to our world that can all be explained using science! Hopefully in the future I'll be able to discuss things like these on here. I know this has been a bit of a lazy post, but revision has just taken over recently - luckily within two weeks they'll all be over!
This post was ready in time, I just forgot to click publish, sorry!
On the 28th February, many Brits could see the Northern Lights in Scotland and surprisingly England and Wales too! I could go all cultural on you about their history and whatever, but that's Tess' job and it's a science post this week. Did you know, the Northern Lights' Latin name, Aurora Borealis, is as it is because Aurora was the goddess of dawn (ie. red skies), and borealis meant northerly?
"The sight filled the northern sky; the immensity of it was scarcely conceivable."
