How To Curve A Baseball Or Swing A Cricket Ball

[TheBanana4life]

lol white caps fc... a terrible mls football team

[rickydeeman]

Pfft, I don't need to do this. I throw my balls so far that the Coriolis Effect does it for me.

[funk192]

I'd like to know about how when you kick a soccerball with no spin ie knuckle ball causes it to swing in both directions.

[mynameisjake17]

@DreJr a football ( i am assuming you mean the spherical one, if not then its just aerodynamics i think ) then the magnus effect is responsible for 'swerve' , air has friction, and the side spinning with the headwind is the direction of motion. (im 17 so sorry for poor vocabulary and explanation)

[naruto57crany]

wow amazing

[ParbelleCondorcet]

Really interesting! Excellent explanations for a complicated phenomenon.

Btw, in the presentation text:

defelected -> deflected

[pinkybrain6]

why does turbulent air sticks to the surface longer? is there a formula, does it has to do with the electromagnetics of the surface of the air and the material, it could probably explain how the schauberger repulsine works.

[ConfusedPingu]

@pinkybrain6 I would of thought it would be due to the fact that more friction is caused by air running over a rough surface e.g its hard to walk on ice due to lac of friction so you "pass over quickly" whereas its easier to walk on a pavement as there is more friction as it is rougher so you "stick" to it. I hope that makes some sort of sense.

[TheMrSteinway]

could you investigate higher dimensions in one of your videos?

[MrAbdulmaster]

subbed :D

[DreJr]

What about a football.  That seems symmetrical all around?

[bridgetisadreamer]

You talk to such interesting people over interesting thing!

[Noogazig]

That professor is awesome - he seems like a great person to know!

[SacredThawing]

What's the song at 3:11?

[beastthree]

please do a commentary on reverse swing. i dont trust the channel 9 cricket commentary's explanations

[leeleeblahblahblah]

are you zachary levi?!

[Timmay08TOTHELIMIT]

Brilliant innings by the aussies.

[garybau2]

now then...how to throw a boomerang!?

[EpicGamingAdventure]

Can you make a video explaining why a plane is affected by turbulent air and why it's bad for a jet to fly in the path of another jet?

[askhoudari]

this is great. now I can go pro.

[Toobis]

I'm liking the whitecaps jersey :)

[aggoor1]

cool



[shintsu01]

interesting stuff like always :D

[f0rzen]

More content please!

[SIC66SIC66]

There is something... about old men.... talking science to young people, that I find funny to watch :D

[MrValzen]

There was a cricket player who bit the ball just to get it rougher, infront of everyone lol

[NicoleNa666]

@MrValzen Afridi, right? Lol.

[Moongazerr]

That old guy is cool and awesome. :)

[ronnie80fan]

Please do a football(soccer) video.

[Canadan20]

beard + Whitecaps polo + EPIC SCIENCE! = perfect breakfast

[x0xpinkipodx0x]

I like that guy

[jawayetti]

Huh. That's how my dad taught me to throw a slider when I was a kid. Never gave the direction of curve a second thought.

[bannanananans]

Old Man: Your going down son!



[Ghost00117]

I'd imagine the turbulent air is moving slower than the smooth air. Would this create a pressure difference on the ball causing it to curve?

[jonasianbuddy]

Would like to know the guests' name!

[1veritasium]

@jonasianbuddy Rod Cross, Emeritus Professor at the University of Sydney

[wyattchung]

@1veritasium cool name. XD

[WorriedMitchell]

What was the music playing during the baseball pitch? That sounds very familiar, anyone know?

[defect530]

Did he make money from an MLB pitcher?

[chris7toronto]

That guy is a genius!

[bibabuzze]

Are curve balls in soccer due to the same effect?

[cssftw100]

@bibabuzze nope - you can't exactly pick up a ball during the game and polish it haha

[1veritasium]

@bibabuzze No, they're due too the Magnus Force - check out our earlier video on this topic.

[c3vzn]

But what about reverse swing, when the cricket ball swings towards the shiny side?

[1veritasium]

@c3vzn Oh, the complications. Rod and I discussed this but you always have to limit the scope of a video. I think it involves the flow on both sides becoming turbulent.

[zacharylisle]

so how does my penis curve left?

[qazxswe5697]

@zacharylisle cause u touch ur self to much with one hand only (same hand each time) XD

[Qmatthaus]

vancouver white caps???

[bradvitaminb]

Great youtube channel. I subscribed a few months ago, and since then there have been several gems. Keep them coming.

[gabygabi007]

Interesting!

[mysteriousgardener]

now a challenge: curve the bullet.

[1206549]

@mysteriousgardener maybe someone can make a gun that would curve a bullet. it wouldn't cause the bullet to spin and it roughens one side of it so it could curve

[FangedBeauty]

Science + excellent presentation x amazing guest speakers + epic beard = fantastic show !

[CrazyLazySnazzyJazzy]

This old guy is a genius.

[chris0419]

hold up, gotta scratch my ball

[KaoFamJK]

SCIENCE!

[justtalkify]

Amazing

[TheQKam]

I love science :)

[MrZacharyPeters]

Your beard = fantastical

[failz1213]

yay!! science!
