Things You Thought You Knew with Neil deGrasse Tyson

Mass? Weight? Density? There are some things you thought you knew and on this episode of StarTalk Radio, Neil deGrasse Tyson and comic co-host Chuck Nice are here to investigate what we know and what we thought we knew.
We start with mass, weight, and density. If you’re trying to get in shape you need to lose weight, right? Neil deGrasse Tyson says wrong. Neil tells us why when you want to get in shape, you need to lose mass. You’ll learn why a weight-loss book written by a physicist would just be one sentence. We explore the difference between mass and weight and why weight is all about forces. Find out why heavy cream is lighter than skim milk. We explore how the hull of a ship keeps the ship buoyant. All that, plus, Neil explains why, if you want to lose weight quickly, just head to the Moon and hop on a scale.
Then, we move on to another seemingly simple question: Why does ice float? Neil explains why peculiar things happen to water when it changes state. We explore what happens when water freezes. Chuck gives a demonstration of why you usually see 10% of ice above water. You’ll learn why the arctic ice sheets float on the water. And, why the ice we need to worry about is the ice on land and the “runoff.” We discuss the power of freezing ice (which leads to bursting pipes). Find out more about the density of water. What if bodies of water froze from the bottom up? Neil tells us how a certain property of water protects aquatic life over the winter.
Lastly, we turn our attention to space. How much do you weigh in space? Neil tells us why we should be thinking about how much mass something contains instead of how much something weighs. You’ll learn why your weight in water is basically zero. Why are astronauts weightless in space? Neil explains how Sir Isaac Newton discovered orbits. Find out why most energy from a rocket launch is not used to get the rocket into space. All that, plus, we explore the science of Ad Astra, The Expanse, and 2001: A Space Odyssey.
Thanks to our Patrons Christopher Sukhanenya, Dmitry Pugachevich, Eugenio Barrera, Dakota Clifford, Nick Mancusi, Nicholas Musial, Sebastian Roser, Bryan J. Jacop, Robert Frasco, and Obumneme Ozoh for supporting us this week.

6:20 Ivory soap loating was a selling point because people were still bathing themselves in rivers and streams, and all other brands of soap would sink and you would lose your soap and have to buy a new bar. So, the developers of Ivory soap created a soap that would float so if it slipped out of someone’s hands, they could run or swim down to grab it. Also, a little fun fact, the exact mixing time for the proper density was discovered by accident, but was proven useful as it could float.

Sitting down to a conversation with these two would be so fun! And I'm glad they brought up the topic of water and ice. Yes, life is only possible because of this 'feature' of water. And maybe they don't want to get too technical, but, it would have been nice to explain why ice expands when it freezes. It's the hydrogen bonding between molecules that makes it form a lattice. And, as an example, a lattice of metal pipes is less dense than a pile of metal pipes, it's the same concept. The shape of the water molecule + hydrogen bonding forces it into a lattice since the molecules interact more strongly at lower temperatures. And maybe the concept of hydrogen bonds is too complicated for a short segment, but, it's a topic that always fascinated me. It's not a full bond. Far from the strongest bond. And yet, it essentially makes life possible. The life-sustaining properties of water, and also our very own proteins and DNA are stabilized by hydrogen bonds.

@@reasonerenlightened2456 I am almost fairly certain that the Earth would not flatten if all the matter is moving at the same pace. I also saw you ask this question in regards to SpaceX and their rockets, and I would like to explain that force of rockets is not high enough to displace the movement of the entire planet, and if it was, the rockets would only destroy the earth, not propel it faster. The planet's surface would break far before it was propelled, even thought both are entirely impossible under the conditions stated. All that would move anyway would be the wind, some water (maybe), and whatever rubble was around these "engines". Hope that clears it up.

Hexagon is the most efficient perimeter to area ratio. Multiple soap bubbles on the surface of a bucket go from round to hexagonal as they propagate and crowd and stick to each other. The same thing happens with bees making honeycomb. The wax cells get put together round, but the additional packing of more cells cause them to find the best ratio to take up the smallest footprint (perimeter,) with the most area. And that happens to be the hexagon. Physics!!

@@mlijah2730 Earth bulges at the equator from spinning at 1Rev/24*60 min. 1rev/88 min. would increase force on the surface and make it bulge more.

I can see him going out and getting a coffee eith him and just sit there for hours listening to this man talk to for hours. I just want him to blow my mind. I love him a lot. Like he’s my uncle and I would cry and my heart would break if something were to happen to them. The universe knew what it was doing. When you created this man he is absolutely wonderful. I don’t like when people talk down on him like how they say he talks too much or interrupts people too much. He is just very passionate and what he does and has a lot of knowledge that he wants to spread he can be very misunderstood and I wonder what growing up for him was like.

As a swimmer who naturally contains my breath inside my lungs, I actually had to learn to sink. As long as I'm conscious I float vertically. Even as a teenager when my body fat was very low compared to what is now, I can literally float in freshwater, so the surface of the water sits at my lips. All it takes is a small flick of the foot or hand to bob above the water, take a breath, then just float there without moving. In order for me to sink, I had to blow all my air out and I sink like a rock.
