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.
Sponsored by BMW
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.

Original Title: Water on the Moon?
For a long time we thought the Moon was completely dry, but it turns out there are actually three sources of lunar water.

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.

Original Title: The American Kilogram
The US signed the metre convention and bases all customary units on SI standards. As an aside, the Utah constitution from 1895 required the metric system to be taught in schools. This requirement was repealed in 1987. ¯\_(ツ)_/¯

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).

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.

Original Title: First Ever Light & Gravitational Wave Cosmic Event!
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.
