Summary: Veritasium is an English-language educational science channel on YouTube created by Derek Muller in 2011. The videos range in style from interviews with experts, such as 2011 Physics Nobel Laureate Brian Schmidt, to science experiments, dramatisations, songs, and—a hallmark of the channel—interviews with the public to uncover misconceptions about science.

Episode 2: The Real Moral Dilemma of Self-Driving Cars
Air Date: January 19th, 2017
Summary: We talk about all the potentially challenging situations autonomous cars could get into but not about how human drivers are not very good. Tens of thousands die on the roads every year in collisions, most of which could be prevented by autonomous vehicles.

I wanted to make a video about autonomous cars for some time but I hadn't had the opportunity. The self-driving technology is already at a state where it can save lives if only it were more widely implemented.
Episode 7: The Bayesian Trap
Air Date: April 5th, 2017
Summary: I didn't say it explicitly in the video, but in my view the Bayesian trap is interpreting events that happen repeatedly as events that happen inevitably. They may be inevitable OR they may simply be the outcome of a series of steps, which likely depend on our behaviour. Yet our expectation of a certain outcome often leads us to behave just as we always have which only ensures that outcome. To escape the Bayesian trap, we must be willing to experiment.
Episode 9: 4 Revolutionary Riddles Resolved!
Air Date: April 18th, 2017
Summary: The solution to 4 rotation-related riddles, including the mystery cylinder, bike pedal pulling puzzle, track problem, and train part going backwards. Thank you to everyone who responded, liked, shared, or made a video response.
Episode 14: World's Heaviest Weight
Air Date: May 24th, 2017
Summary: How do you measure big forces accurately? By calibrating your force transducer on the world's biggest weight - 1,000,000 pounds of force. This machine ensures planes don't break apart, jets provide required thrust, and rockets make it to their destination.
Episode 15: NEW Gravitational Wave Discovery!
Air Date: June 1st, 2017
Summary: Scientists have JUST published this new observation. On January 4th, 2017 they detected the merger of two black holes 3 billion light-years away. This marks the furthest detection they've been able to make and increases confidence that these events will be seen with increasing frequency as the LIGO interferometers become more sensitive to low amplitude gravitational waves (as sources of noise are eliminated).
Episode 16: Sandwich Bag Fire Starter
Air Date: June 8th, 2017
Summary: The intensity of sunlight on Earth is about 1300 Watts per square meter. When you focus the sun's rays using a magnifying glass (or in this case sphere of water) you can increase the intensity roughly ten thousand fold. This increases the temperature of wood to its autoignition point starting the reaction with oxygen in the atmosphere. By protecting the hot embers and adding more energy and fuel, you can get these hot coals to start a roaring fire.
Episode 22: First Ever Light & Gravitational Wave Cosmic Event!
Air Date: October 16th, 2017
Summary: The merging of two neutron stars was detected by gravitational waves and then by telescopes in all parts of the electromagnetic spectrum. This is a historic detection as it demonstrates -
- the first gravitational waves detected from inspiraling neutron stars
- the first joint observation by gravitational wave and electromagnetic wave astronomy
- identification of a gamma ray burst in conjunction with merging neutron stars
- how gravitational waves and gamma rays can be used together to locate their source
All evidence so far indicates that the data support General Relativity.
