Why We Need Zip Lines On The Moon

The Rest Is Science

403,025 views

Why would a zip line be the best form of transport on the Moon? Why exactly can your feet still feel other textures right through your socks?

Hannah and Michael tackle the spectacular physics of extreme commutes and everyday biomechanics. They unpick the orbital chaos and terrifying vacuum of space, proving why a lunar theme park ride is essentially a brilliant, fiery death trap. Back down on Earth, they dive into the hypersensitive neurology of touch, revealing how your brain decodes microscopic vibrations through layers of cotton to perfectly map the floor beneath you.

To top it all off, Hannah shares her very old school, steam punk esq, mechanical calculater.

We should just gently lower the moon until it meets the surface of the earth and we can just store it in alaska and drive there for moon stuff

Yes to 'Mental Math Tricks' episode.

I feel like every time I open YouTube there is a new episode. Grateful for this podcast

I can’t get it out of my head how the word TOMATO is hiding in FRACTOMATOR

I think Michael saying "Show US how it resets" instead of saying "show ME" says a lot of good things about his character and how he feels about the audience.

34:25 Petition for Michael to ACTUALLY give us a tour of his office; it looks so cool with all the paraphernalia 🥳😂😂

The explanation that made the monty hall problem click for me is when you scale the same problem up. If you have 100 doors, you pick one, then the host eliminates 98 more of the doors it unlocks your intuition. Your original choice you had a 1/100 chance to select the prize. After 98 more doors were eliminated, you can see that it's now obvious that the prize is way more likely to be in the last remaining door rather than your original 1% chance pick.

Ngl your explanation of the monty hall problem is the first one that made it click for me and now im confused bc how is that hard to explain? why have so many done an absolutely abysmal job of it? Wow. Anyway, somewhat irritated it was that simple the entire time, but im glad i get it now.

The monty hall is a problem that has been complicated by the wording of the question and even more complicated by the wording of the answer, when in reality once you hear the solution properly, you will have your lightbulb moment....

I feel like the monty hall problem is more intuitively understood if you equate it to "would you rather choose one door, or two doors"? Because switching after one of the three doors is open is effectively equivalent to picking two doors.

Yours was definitely the best explanation I've heard of the Monty Hall problem.

@KumiKaze33 4 weeks ago (edited)

I didn't know it was called the Monty Hall problem, but once described I remembered it. I remembered it from an episode of "Numb3rs" and thought it was described very clearly on that episode, which is why I remembered it so well.

I would love an episode on mental math tricks. Would also love to know what got cut out of the end of the last episode.
I love little mechanical math things, they're so interesting to me, both in how they're designed and how they affect our ability to understand the math.
Also, the conversations about base 12 vs base 10 are some of my favorite tidbits.

8:10 Even if you made a space elevator all the way to geostationary orbit, where you have this effect of satellites hanging in the sky like you are saying, that is far beyond the orbit of most satellites that move around the earth. As a result, you would have enormous stresses in whatever elevator you constructed, since most of it would lie at lower, non-geostationary distances that do not naturally "want" to stay in the same orientation. This is essentially an expression of centripetal stresses and inertia.

That calculator is so amazing. Having to actually physically lift and carry the 1 over to the other side adds a sense of tangibility that makes calculating feel more real, rather than nebulous rules to memorize (like Michael said)

52:17 a rare moment of Michael having a genuine laugh

@Richie2390 5 months ago

Is the best description of the Monty Hall problem ever 22 minutes into this video?
Listening to them explain it just makes it seem so sensible and makes so much sense. For some reason, it feels like it's a better description than the Vsauce video. Maybe hearing Hannah reiterate it in such a simple way is what makes the difference.

Great episode! Just to say the question slides are tricky to read (for visually impaired) white text on a pale background. Perhaps you could make a greater contrast? Thanks
