Bill Nye ’77 on the physics of flying discs

[@KW-qd8gu]

Finding out that Bill Nye plays my favorite sport just made my day

[@raddaks2039]

The inner child in me is very happy.

[@JacksonOwex]

@@raddaks2039 The child in me feels OLD seeing him getting old!

[@beenschmokin]

He also thinks little boys are trapped in girl's bodies...

[@Javaman92]

Same here, disc golf rocks!

[@Janiix89]

Right?!

[@TommyGunz3]

Never would have thought Billy Nye the Science Guy would teach me about Disc Golf. But I am here for it!

[@seymourglass26]

But now that you're seeing it, are you surprised? I mean, it's basically aerospace engineering in sport form.

[@cable7152]

​@seymourglass26 it makes perfect sense actually, not surprised at all he plays disc golf.

[@jeffreyhomburg822]

He was an Ultimate player and coach back in the 1970s and he's been playing disc golf more in recent years, with players like Stork (#003) and other legends of the game!

[@blee916]

Playing a round with Bill Nye goes straight on the bucket list

[@Subdivision21]

PLEASE PLEASE DO AN ADVANCED PHYSICS TUTORIAL SERIES ON DISC FLIGHT 🙏 Bill Nye the Disc Flight Guy

[@ryanfawcett33]

He's no Bill Nye, but this was an excellent video made a month ago on the physics of why discs fly the way they do! I learned so much. ua-cam.com/video/fL4DhAMiiHI/v-deo.html&ab_channel=PeteUlibarri

IM GLAD IM NOT THE ONLY PERSON TYPING IN ALL CAPS HERE

[@untrustworthyshelfing9953]

Forget flight numbers, I need equations on my discs.

We need Bill Nye on a Jomezpro practise round!

[@EricJenkinsDiscGolf]

This would be epic 🤘

[@charleslybrand4342]

I NEED MORE OF THIS! Bill please! I beg you! Do a 30 minute special on the dynamics of discs in flight! PLEASE!

[@danielschwagler6229]

He throws like an ultimate player.....awesome to see one of my favorite guys playing my favorite sport. Been showing his show to my students for years and there's nothing better.

[@ar374]

I believe he played ultimate for the Buds when he attended CU

[@sethgreenwood6488]

It says in the video that he started an ultimate team

[@Xevv0s]

One of the disc golf companies better make a bill nye “tour” series disc

[@wilsondiscgolf00]

Innova just did

[@carterbotto1992]

Is no one going to talk about the fact that he is throwing all green discs? Savage

[@DiscGolfandOATmeal]

More physics on disc golf... More More More More 😊

[@grimrecords19]

My favorite “scientist” plays my favorite sport, at 77. Hero.

Love to hear Bill break the flight physics down!

[@BiteNuk3r]

That needed to be much, much longer. More Bill playing disc golf please!

[@austinmreynold]

As a fellow hucker of discs this absolutely was the best thing to pass by my feed all day

[@davegreen8569]

I ran into Bill Nye years ago while picking up hiking permits at the base of Mount St. Helens. Saw him again along the rim. He was strapping on backcountry skis. Next to glissading down the mountain, meeting Bill in his natural environment was the highlight of the trip.

[@Reverend_Mojo]

Now I want to see a Bill Nye In the bag, I NEED to know what discs he throws!!!

[@lsapg09]

BUT BILL, HOW DO I GET MY HYZERS TO BE NOSE DOWN?

Without proper punctuation that statement sounded really weird

[@adamgrigsby9372]

I love that Cornell's logo looks like a disc golf basket.

[@aramdg]

god, I love Bill.

[@grunskm1]

Hear me out: All discs have sub-optimal airfoils because they must be symmetric due to rotation. This causes discs to be especially prone to stalling, which causes them to pitch up as they lose energy. However, due to the rotation of the disc and the effect of gyroscopic procession, the pitching-up motion is instead realized as a roll, causing the characteristic fade to left at the end of a right handed backhand.

[@Flyzguy]

Oh my gosh I found someone else who knows this!!! And the high speed nose down moment of discs with a lot of camber ("low wing") to roll right for RHBH. It's all just airfoil pitching moments and forces - but precessed 90 degrees!

[@grunskm1]

@@Flyzguy Yes! A slept-on aspect of disc flight dynamics. I'd love to see someone like Scott Manley cover this.

[@Flyzguy]

I could run some CFD cases and contribute. I'm a professional aerospace engineer and I've done some educational work, but I have no video production experience

[@nktaylo1]

The Marie Curie MVP Reactor exists; I would pay good money for a Bill Nye MVP Inertia. I'd pay a lot of dollar bill, bill, bill, bill, bill, bills!

[@jojog8304]

Spinning disc = 1d gyroscope
Edge lip = airfoil
Together it holds orientation (gyro)and flies(airfoil)...
Mind that anything with a coeff of drag will "fly", some bad some good.

[@sleepyjesus7265]

This is a good start, but a more thorough explanation of the physics of turn and fade would be very interesting to hear. I've argued a lot with my buddies about why the disc behaves how it does and which features of the disc exactly cause under or over stability.

[@jahmic]

I'm starting to like this timeline again.

[@vtmike13]

I love that Bill Nye is into the same two niche things as me--- disc golf and swing dance

[@tfilipow7]

Please get Bill to play a celebrity round. We need a Pro Am in disc golf to get some more viewership from the main stream.

[@ThrowinWithOwen]

Dang, didn't know Bill was chill like that.

[@mightypensword]

One of my childhood heroes.

[@chapstickit]

Reppin the DC Breeze hat!! We know which disc sport is in his heart ;)

[@spikehyzer2323]

I knew it! The recent test of spin rates had 3 women in the top 15 even though they all had 10 MPH less arm speed and significantly less distance.
EVERYONE on that vid said spin equals distance. I countered that arm speed equals distance and spin helps hold the line (throw a weak sky anny and it goes as far but tails out).
And Bill just affirmed it! He said the spin is for holding the line.

[@fodank]

You go, Bill. I'm seventy and still throwing. Will be as long as I can and then some in the next life.

[@ryandaley1270]

can one of these disc manufacturers put Bill Nye on payroll to make disc golf videos promoting the sport? Pros like Ricky Wysocki or Nate Sexton are always putting out beginner/promotional videos for disc golf, but I think we need Bill doing these! Who do you think someone with no disc golf knowledge would listen to? Pros Ricky Wysocki/Nate Sexton, or Bill Nye the Disc Golf Guy!

OK now who do I kick off my dream card to add Bill?

[@ericjepson3765]

Dark art indeed

[@roddinandracin1153]

This is awesome, now if I only understood scientific terms

[@shneekyshnake]

Ok Bill but what makes an overstable disc an overstable disc? Why does it cut to the left when thrown with a Right hand back hand and cut to the right when thrown with a Left hand back hand??

[@spartacus10]

Quite a few factors there, but I believe the main differences come in the injection molding phase. Here's a quick vid of that: ua-cam.com/video/Tkr5W90hXnQ/v-deo.html . The higher the parting line is (line on the outer rim) the more over-stable the disc will generally be. That has to do with how it interacts with surrounding air as it flies. For a 12-14 speed the line is high and those discs have to be thrown at high RPM to get them to fly as intended. Lower RPM means mode fade for drivers. For putters and mids the speed/rpm to stability math becomes different. Then there's all the different plastic types, how many nicks a disc has, textured rims/patches on disc etc. Could make a long video out of that. But main difference comes down to the parting line. Super domey discs will be beefcakes.

[@shneekyshnake]

@@spartacus10 Why does it go left and not right though? (RHBH)

[@ajr2112]

​@shneekyshnake It's actually really complicated. I looked into this and long story short, it's because the disc is a gyroscope and therefore it has angular momentum; whether the force of lift (i.e. the torque applied to the disc) is centered infront or behind the center of the disc while it travels will determine if it "turns" or "fades." things that impact the location of the center of lift are the shape of the disc, how fast the disc is falling, and nose angle. Understable discs usually have a more convex dome and less of a ramp angle on their rim. Overstable discs are usually flatter on top and have a steep ramped rim.

[@Flyzguy]

Yep AJR has it right. To understand a disc rolling left and right, we have to understand it's a gyroscope with forces trying to pitch it up or down. At the end of a flight the air is hitting the nose at a higher angle of attack, trying to push the nose up. Depending on spin direction, this nose up torque precesses (gyroscope) acts like a left or right roll.

[@shneekyshnake]

@@Flyzguy Found some good explanations when looking up the Magnus Effect

[@elliotmcconnell5449]

Ah. This is cornells little 9 hole course. Thats where I first played!

[@johanekekrantz7325]

The most simultaneously interesting and confusing physics of disc golf is fade and turn. If anything needs a nice clear explanation, thats the one.

also dont forget to look at datass

[@roblol5481]

A driver does not have more weight further out in the rim. (Moment of inertia). In fact a putter has more weight at the rim than a driver does.
They have the same diameter, same weight and comparable flight plate thickness. The putter has all the weight of its rim far from the discs center while the driver stretches the weight closer to the center with its wide rim.
The stablility and flight differences between putters and drivers comes from the wing shape han how it creates lift. Where the center of lift is compared to the center of mass on the disc, and how this changes at different speeds.

[@MrDong101]

It's nice to see he found his way back into his lane.
