How To Make Parabolic Mirrors From Space Blankets - NightHawkInLight

Parabolic mirrors are useful for everything from solar power to telescopes to holographic projection. They're usually very difficult to make by traditional means, but this video takes a different approach. Check out my sponsor Rayton Solar here: http://bit.ly/Rayton-Solar With their incredible silicon cutting process via a particle accelerator they're able to make solar panels with virtually zero waste and a higher efficiency result. AN OFFERING STATEMENT REGARDING THIS OFFERING HAS BEEN FILED WITH THE SEC. THE SEC HAS QUALIFIED THAT OFFERING STATEMENT, WHICH ONLY MEANS THAT THE COMPANY MAY MAKE SALES OF THE SECURITIES DESCRIBED BY THE OFFERING STATEMENT. IT DOES NOT MEAN...

World's sharpest Tele lens! Moon, 300x zooming in! 4K, UHD, Leica 2.8/400 mm

World's sharpest super telephoto lens? The video clips where filmed in August 2015 at only 290m above sea level. (Camping side in Germany) Some zooming in and out, and spinning in post production with Magix VDL 2016. Panasonic GH4 and a modified Leica 2.8/400mm + 1.4x + 2x + 2x Leica Apo Extender. I wanted make the viewer, to feel like observing the moon from a space craft. I made some test with a "Siemens Star" this summer, resolution = 1mm at 480m (0.43 arcsec.) !! This means 1200 lines/mm, of course wide open! Also read: Diffraction-limited system ...

Freezing 200,000 Tons of Lethal Arsenic Dust

Giant Mine sits near Yellowknife, in the Northwest Territories of Canada. Once it was a productive gold mine, but after the gold ran out, the mining company went bankrupt and left the government to clean up the mess: enough arsenic trioxide dust to kill everyone on Earth. The solution: freezing it, at least for now. Thanks to all the team at the Giant Mine Remediation Project!

Drones vs Lightning ⚡

At the University of Manchester's High Voltage Laboratory, we see what happens when a DJI Phantom 3 drone gets hit with an electrical impulse of 1.4MV - basically, a lightning strike. Actually, two Phantom 3 drones. We had a backup. Thanks to the team at the High Voltage Lab! Here's their side of the story: http://www.mub.eps.manchester.ac.uk/science-engineering/2017/04/10/drone-vs-lightning/ And here's a teardown of the drone: http://www.mub.eps.manchester.ac.uk/science-engineering/2017/05/11/inside-the-drone/ The University of Manchester's YouTube channel: https://www.youtube.com/universitymanchester You can also follow on Twitter: The HV Lab http://twitter.com/HighVoltage_UoM Vidyadhar Peesapati http://twitter.com/DrViddy Manchester Energy http://twitter.com/mcr_energy School of Electrical and Electronic Engineering http://twitter.com/eeemanchester Main camera: Fraser Cottrell / http://www.frasercottrell.com Edited by Michelle Martin / @mrsmmartin Audio mix by Matt Gray...

Gender Neutral Pronouns: They're Here, Get Used To Them

http://tomscott.com - @tomscott - Grammatical gender is a silly concept. So I'm about to go against my vow of descriptivism, and risk being run over by the Linguistic Mafia's bus, and say this: it's a silly idea. [The line about "the first sentence of the video" is wrong: it's not actually in the first sentence of the video. I cut that line, and forgot about that second line. Whoops.]

A Nuclear Waste Dump You Can Walk On: Weldon Spring, Missouri

In Weldon Spring, Missouri, there is a strange, grey, windblasted seven-storey pile of rocks. It's the Weldon Spring Site: a nuclear and toxic waste dump on the site of an old uranium processing factory. And you can walk on it: it's technically a tourist attraction. That was going to be the whole of my video... and then I did some more research.

How Computers Compress Text: Huffman Coding and Huffman Trees

Computers store text (or, at least, English text) as eight bits per character. There are plenty of more efficient ways that could work: so why don't we use them? And how can we fit more text into less space? Let's talk about Huffman coding, Huffman trees, and Will Smith.

The US President's Bulletproof Railcar

US Car Number 1, the Ferdinand Magellan, sits in the Gold Coast Railway Museum in Miami. It's 120 tonnes of bulletproof, armoured railcar: a train carriage designed to move the President of the United States around the country in safety and style. At least, it was, until other transport came along to do a better job.

Making Artificial Earthquakes with a Four-Tonne Steel Ball

In Göttingen, Germany, there's a four-tonne steel ball that can be raised up a 14-metre tower -- and then dropped in less than two seconds, crashing back to earth. It makes tiny, artificial earthquakes: here's why. Thanks to all the team at Wiechert'sche Erdbebenwarte Göttingen! You can find out more about them here: https://www.erdbebenwarte.de/ Three things I had to cut out of this video, because they didn't quite fit into the story or because I couldn't film them: The reason the steel ball survived two world wars is because the university's records listed it by use as a "rock-ball", not by composition as...

The most significant genius: Emmy Noether

There are a few people in the history of physics who have made insights that have revolutionized our understanding of the interactions of math and physics and given us real insights into the meaning of our theories. In this video, Fermilab’s Dr. Don Lincoln tells us of the tale of Emmy Noether – one of the most significant geniuses of the last century.

Is It Dangerous To Talk To A Camera While Driving?

How Zero-G Planes Work

The European Space Agency offered me a seat on their zero-g plane: it's an Airbus A310 that flies parabolic maneuvers, pulling up into the sky and then arcing back down, giving its passengers about 20 seconds of weightlessness (or "microgravity") at a time. Here's how it works. Some people would have filmed their script on the ground, and just messed about while floating. I decided to go for something a bit more challenging. ** If you're a masters or PhD student from an ESA member state, and zero-g sounds like your thing, have a look at the Fly Your Thesis program: http://www.esa.int/Education/Fly_Your_Thesis --...
