Sticky Science: The Force Be With You with Neil deGrasse Tyson
Ғылым және технология
What are Van der Waals forces? On this episode, Neil deGrasse Tyson and co-hosts Chuck Nice and Gary O’Reilly explore the fascinating world of surfaces, biomimicry, and Formula 1 with physicist and author of Sticky: The Science of Surfaces, Laurie Winkless.
What’s up with gecko feet? We break down how geckos defy gravity and the hierarchical structure of their lamellae that makes them so sticky. How close do gecko’s feet get to the surface they’re on? We explain Van der Waals interactions and the groundbreaking applications of gecko biomimicry for us humans.
What does “laying down rubber” mean? Learn about the forces at play on Formula 1 tires. What do they have in common with gecko feet? Discover tribology and the principles of friction. How do rubber tires work? Is there a way to make them faster? How does a tire make contact with the road? We discuss rain tires and new materials like carbon carbon.
We also explore the physics of other special surfaces. Can we make a boat that never gets wet? Find out about the Salvinia fern and how its helping scientists create the ultimate low friction coating. How do golf balls reduce friction in the air? Is the air also sticky? You’ll also learn about how Sharks reduce drag using their dermal denticles. All that, plus, how can Chuck become spiderman?

If the boat never gets wet would it have get barnicles and algae on the bottom still or would that not be a problem because no water?

Specially Lord Chuck Nice , the way he articulates his thoughts is so much thought through you would think he has masters in Linguistics.
I’ve been following this channel for quite a while and I regard Sir Neil deGrasse Tyson as my greatest teacher in life. But I have to say Chuck Nice, my guy, you show an amazing growth. It just goes to show, you’re infected by those you hang around. The intelligent questions you ask, your crispy sharp reactions and well timed jokes…my deepest respect to you! Thanx for all the lessons and helping us see the magic of the universe in the most tiny things! By the way, as a kid in West Africa, I used to be amazed at the grip of a gecko so this episode was extra special. Lil side note: me and my friends used to go on gecko and salamander hunt at night. We were quite cruel cuz we used to be amazed by the tails of these animals. Don’t judge me, I was a bad kid at 8😜
Man, I had a rough day and have been looking forward to listening to this after work, and the first segment ab geckos turned my mood around. I love this podcast so much. Thank you StarTalk crew! 🙏
Just got Ms. Winkless' book on Audible. I like the way she teaches.
Laurie Winless was an absolutely fantastic guest and super questions from everyone. I have always wondered if when painting the bottom surface of a boat with a paint that created very small but measurable dimples like a golf ball, how that would affect the flow of water along the surface. Also wondered if you could have the surface of say a submarine exude a thin layer of water how that would affect its slickness and speed. Thank you all for a wonderful Friday evening.
Amazing show. Singing a few bars of the Speed Racer car toon theme song was icing on the cake. Tremendous chemistry with all four of you. ❤️
AHHH!!! I actually STUDIED geckos in college in a course on biological design. We actually made mock-adhesives based on the physical structure of gecko feet. Very cool!!! 😃
Yay more Neil

As the proud human of 4 crested geckos, nothing better than watching them hanging around in every which way, like they defy gravity! They're amazing creatures!
I remember when I was into rowing (In my teenage years) and the tech staff in my club explained me they used to scratch the boat surface with sandpaper of a certain size so that air bubbles would stuck to the boat’s surface. We are talking 20 years ago

Speed racer... talk about a blast from the past. Great episode, will definitely order a Sticky copy 👍
What a real nice episode. Laurie was a delight, as Neil said. About the sharks, though Chuck, not all sharks have to keep moving to breathe. I've seen sharks chilling out, laying in the sand at the bottom of aquariums. Examples are the nurse and tiger sharks.
my favorite thing to hear... @32:50 'I'm not sure. So I won't pretend to know"
Please make it daily!!!! ❤️ This show is like drugs to me
I absolutely love the childlike giddiness that they all have for learning and the pure joy they have at discovering the amazing ness of geckos!
Greetings from northen Sweden and a long time subscriber. I have a crested gecko and he does not like wet or moist glass. If I spray water in his tank (terrarium) and he moves over that surface he just slides over the glass or even falls off. Crested geckos, according to my son are the ones that does not grow their tails back if they loose it.
Absolutely amazing episode!!! One of my favorites ever I'd love to see another one with her, I blown away how she seems to know about so many different topics The part auf F1 was so exciting as a big F1 fan
Still catching up here. This was a fun episode again. Learned a lot today, thanks.
Enjoyed this episode but the best bit for me is the 'gecko doing jazz hands' 😂😂now that is something I'd like to see 👋👋
This is my FAVORITE episode
Top notch. One of the most interesting episodes.
Chuck you are more important to this show than you know. You are far from the waterboy my friend. Someone however needs to be more active in the comments section. I vote you chuck
If I could do it all over, I would definitely try to get into material sciences, it's always so fascinating
As a tribologist, I think its about time you covered us. :)
Amazing talk, wish it lasted longer
Brilliantly Done!
Always great to see Lord Nice!

I want to like this a thousand times!! Great episode Dr Tyson!! Geckos…who knew they could be so fascinating?! I’m absolutely obsessed with them now!!! Please bring Laurie back for more explainers!! She was fantastic!
I love learning new things, always thought geckos had suction cup toes, who knew that they had hairy toes...
Surprisingly entertaining episode
Awesome guest, cheers Laurie
Nature gets cooler every time I watch one of these videos
As someone who wasn’t interested in science before my husband introduced me, this is SO interesting. I went into a deep dive of Gecko toes!!! Thank you for explaining so well! I can’t wait to learn more!!!
I love your show!!
Mr. Tyson can you make a video about the science of bubbles. How they form to be spheres etc?
So Gekkos are a webshooter away from being Spider-Man. This was fascinating and I LOVE the accent. Now I'm off to look up carbon carbon.
Gary knowing that little tidbit about why cartoon characters usually have 4 fingers instead of 5 is a deep cut. I learned that in animation school.
Great show. 👍
Neil, could you provide Portuguese subtitles on your channel! thanks
Let the Force be with you. ~ Fields. (Thank you for spreading cosmic curiosity, love these videos.)
Such an interesting topic. The explanation of capillary action of our moist skin on surfaces explains why a satin finish on a guitar neck is smoother "faster" than a gloss finish.
It would be interesting to hear about sails and modern fabrics used for sails.
Never thought I would be fascinated by Science this much ...would've finished nursing school ❤
Great host, great jokes, Gary also has had a bigger role lately. Excellent episode! 😀
Great episode
Chuck plays end, guard and tackle. Sits at the end of the bench, guards the water and tackles anyone who comes near it. Doh!
Hi from New Zealand. You should also bring back that volcano expert (the Kiwi one)... well, both volcano experts you have are great.
I didn't wanna watch this, but after doing so..as usual...no regrets..I learned alot today
Laurie is amazing. Never thought I would learn so much
Chuck really showed out on this one… he dropped the act and proved he’s got a grasp on practical concepts that seemed to rival even Neil.
Great video
Love this automotive themed episode. also drag racing has VHT track spray which enhances adhesion of tires the road.
This is just getting better amd better aaaallllll the time this podcast...this is just out of this world good wow...kudos guys🙌🙌🙌🙌🍻🍻🍻🍻🍻

My Irish heritage (county Cork) resonates with her big time. Love Irish-accented English
Some of these topics don’t initially sound interesting to me, but I am always pleasantly surprised.
They spray traction compound on the track for better traction in some racing programs. Like glue for lack of a long drawn out explanation
Get a grip 😂😂😂 Absolutely love this show 💙
Mannnnnnnnnnnn, I'm so glad I found this channel!
15:38 Thanks Neil I feel very special
During the first year of my physics degree I learned about Gekos using van der waals forces to stick to the walls. When I tell people they seem mainly unaffected by it, or try to retort with something about a hippo or some other trivial thing. :) I like being rich.
I love you guys a whole lot.
One of the best videos yet. Hung on every word spoken. lol
Laurie is delightful - very entertaining to listen to. Fascinating topic - materials science and surfaces is one of my favorites. Don’t Panic - The answer is 42. :-)
I love how much she knows about F1 :D

Gotta love that necklace
I think Chuck fell in love with this guest today , I've never seem him act like this b4 😂
I think it's one reason drag racers do a huge burnout before beginning. The race to the finish line is to gain traction by heating up the tires and making them more pliable.
it's adorable how neil thinks chuck is the most hilarious guy in the world. they must be really good friends
As a contractor, Chuck, do not recommend flex seal. I have to fix the homeowner mistakes by using it. It is not roof sealant.

Yet another fun vid. Do have to comment the "Don't Panic" necklace/medallion is missing the exclamation! do not get geckos toe to toe.
Like a golf ball...we would paint boat bottoms with house rollers to keep the surface from being smooth and prevent it from being a suction cup onthe water, that's how it was explained to me
This would have been the perfect video for the guests to have a few images that they had ready to share with everyone else including the audience and y'all could have had those images like edited into the video in post
