Panem finds power in the radiance of the sun, and the water which rains down upon us! District 5’s Chief Energy Researcher Derek Muller takes CapitolTV on a tour of our nation’s cutting edge renewable technologies, and demonstrates one of the largest ‘Kelvin’s Thunderstorm’ experiments ever built to date… all for a brighter and more efficient Panem.

Sanctioned by the Capitol Ministry of Information, DISTRICT VOICES was made with friends from Google – http://artcopycode.com/campaign/lionsgate

Rubens’ Tube is an awesome demo and here we take it to the next level with a two-dimensional ‘Pyro Board’. This shows unique standing wave patters of sound in the box.

The pressure variations due to the sound waves affect the flow rate of flammable gas from the holes in the Pyro Board and therefore affect the height and colour of flames. This is interesting for visualizing standing wave patterns and simply awesome to watch when put to music. Thank you to Sune Nielsen and everyone at Aarhus for sharing this demonstration with me! And thanks for having me at your conference.

In this video I attempt to lift a 19kg (42 lbs) wheel over my head one-handed while it’s spinning at a few thousand RPM. This replicates an earlier experiment by Professor Eric Laithwaite. He claimed the wheel was ‘light as a feather’ and could not be explained by Newton’s Laws. I wanted to find out for myself what I really felt like.

Why do you make people look stupid? http://bit.ly/12Fmlpl

How do you investigate hypotheses? Do you seek to confirm your theory – looking for white swans? Or do you try to find black swans? I was startled at how hard it was for people to investigate number sets that didn’t follow their hypotheses, even when their method wasn’t getting them anywhere.

In the video I say “when people came to Australia…” by which I meant, “when Europeans who believed all swans were white came to Australia…” I did not mean any offence to Indigenous Australians who were already in Australia at that time. Please accept my apologies for the poor phrasing if you were offended by it.

This video was inspired by The Black Swan by Nassim Taleb and filmed by my mum. Thanks mum!

Partly my motivation came from responses to my Facebook videos – social media marketers saying ‘Facebook ads have worked for me so there can’t be fake likes.’ Just because you have only seen white swans, doesn’t mean there are no black ones. And in fact marketers are only looking for white swans. They think it was invalid of me to make the fake Virtual Cat page: ‘well of course if it’s a low quality page you’re going to get low quality likes.’ But my point is this is black swan bait, something they would never make because their theory is confident in the exclusive existence of white swans.

Is 45 minutes really the longest anyone can stay in a perfectly silent, pitch-black room?

Many stories have circulated claiming the longest anyone has stayed in an ultra-quiet anechoic chamber is 45 minutes, the reason being any longer would drive you insane. To me this sounded like unsubstantiated rubbish, like the claim the Great Wall is the only manmade structure visible from space. So I put my own psyche on the line, subjecting myself to over an hour of the most intense quiet on Earth. No, this was not THE quietest room on Earth (-9dB) but it is one of the quietest, and the truth is once you put a person inside, they are by far the loudest thing in there so the sound rating of the room is irrelevant.

I was not surprised to find that I could stay in there for as long as I liked and feel perfectly fine. What was surprising is that my heartbeat was audible. You can hear it on the sound recording. Now I wasn’t consciously aware of the sound of my heart while in the room, but I was more aware of the feeling of it beating.

Evidence Facebook’s revenue is based on fake likes.
My first vid on the problem with Facebook: http://bit.ly/1dXudqY
I know first-hand that Facebook’s advertising model is deeply flawed. When I paid to promote my page I gained 80,000 followers in developing countries who didn’t care about Veritasium (but I wasn’t aware of this at the time). They drove my reach and engagement numbers down, basically rendering the page useless. I am not the only one who has experienced this. Rory Cellan-Jones had the same luck with Virtual Bagel: http://www.bbc.co.uk/news/technology-18819338

The US Department of State spent $630,000 to acquire 2 million page likes and then realized only 2% were engaged. http://wapo.st/1glcyZo

I thought I would demonstrate that the same thing is still happening now by creating Virtual Cat (http://www.facebook.com/MyVirtualCat). I was surprised to discover something worse – false likes are coming from everywhere, including Canada, the US, the UK, and Australia. So even those carefully targeting their campaigns are likely being duped into spending real money on fake followers. Then when they try to reach their followers they have to pay again.

And it’s possible to be a victim of fake likes without even advertising. Pages that end up on Facebook’s “International Suggested Pages” are also easy targets for click-farms seeking to diversify their likes. http://tnw.co/NsflrC
