Elon Musk’s plan to get humans to Mars can only be achieved if they first get people to space. For this, they have built the Crew Dragon capsule, which will finally start testing at the end of this year, with the first astronauts scheduled for Spring 2019.

SpaceX’s Crew Dragon capsule is a manned version of their Dragon cargo capsule. Fully autonomous with room for 7 passengers, this is the most advanced space craft ever built. Along with the new Boeing Starliner, this will give NASA 2 different options to send up astronauts for the first time in their history.

Launching astronauts into space from American soil would be the first time that’s happened since 2011, when the famed Space Shuttle flew its last mission. The first two astronauts to fly on Crew Dragon are Bob Behnken and Doug Hurley, two seasoned astronauts with years of experience between them.

My Tesla Model 3 Delivery!

After 2 1/2 years of waiting, my Tesla Model 3 is finally here!
Today’s video is a little bit different, more of a vlog-style where I document the delivery and my first impressions of the Tesla Model 3.

Everything Is Memory

Today we go a little deeper and talk about the mystery of memory.

From Plato’s Allegory of the Cave to The Matrix, we’ve believed that reality is not exactly what we experience. Can that be because of the fact that we are all living in our own simulations – the conscious experience that our brain creates.

And this imagined reality creates the beliefs that we cling to and create our worldview around.

US Schools Start WAY Too Early

From lower test scores to depression and even traffic deaths, the evidence is piling up that early school start times are bad for teenagers. So why do schools in the US start so early?

Teens have different physiological needs when it comes to sleep, due to their changing bodies and the energy needs that go along with it. Because of this, multiple health agencies including the Centers for Disease Control, The National Sleep Foundation, The American Academy of Sleep Medicine, American Academy of Pediatrics, and the American Medical Association have pushed for later start times – 8:30am or later.

But for various reasons (usually money) only 1 in 5 schools actually start at the recommended time.

Plastic is a surprisingly recent invention, and it’s become completely ubiquitous in our society. It’s solved a ton of problems and made our way of life possible. It also might be killing us.

The Population Explosion – Was Thanos Right?

Get two months of Skillshare for free: https://skl.sh/joescott In Avengers: Infinity War, the Mad Titan Thanos wants to wipe out half of all life in the universe as a way to save it from overpopulation. This is clearly evil. But is he right?

The first person to sound the alarm about overpopulation was Thomas Malthus in 1798. His belief that overpopulation will lead to unimaginable suffering became known as a Malthusian Catastrophe.

Many years later, Paul Ehrlich wrote about overpopulation in his book The Population Bomb, and predicted that the 70s and 80s would be times of famine and suffering around the world.

This didn’t quite pan out. Julian Simon, an economist, challenged Erlich to a bet to see if commodities went down over time. They did.

And Erlich lost the bet. Today we know that as society develops, the birth rate goes down, meaning that the population will level out eventually.

But we still need to evolve our lifestyles to be more sustainable if the Earth is going to be able to manage over 10 billion people.

Ion drives are a type of propulsion that provides a very small amount of force over a very long period of time, giving it the ability to build up to incredibly fast speeds.
