Zhong-Lin Lu, William M. Keck Chair in Cognitive Neuroscience and Professor of Psychology and Biomedical Engineering, proposed that the "break" in a curveball that fools some batters is a visual illusion. "Curveballs do curve," Lu says, but in a conversation with USC Pitching Coach Tom House, he explains why a perception of a sudden drop or other change in trajectory is a trick of the eye. This study was published in the scientific journal PLoS ONE. To read the whole story, please go to: Video by Mira Zimet and Zane Fried.

If they're saying that a curve DOES curve, but we perceive it different at high speeds as opposed to slowed down using a? camera... that's not that special. Anything will look different when slowed down with enough frames. Change the video title as well. WTF is with calling it "Does a curve really curve" if the answer is still yes!?

Maybe these people still wondering if a curveball curves should get behind the plate and try to catch one. There, you're dead center with the ball, so there's none of this peripheral BS excuse. And yes, it does curve. Have a pitcher show you a fastball. Then have him show you a curveball. There's a huge difference. It's not as though we see a fastball as a curveball as well--due to some BS peripheral phenomenon. Anyone still asking this question needs to get out of their? cave.

So what he is saying is? that the ball does "curve", but any downward movement is an optical illusion? It curves AND drops, but the drop is due to the arc and velocity of the pitch.

(Not to be rude and all )They talking about how a? curveball breaks and its a opitical illusion There talking non-sense

They should do one about if a 4 seam fastball? goes straight.

please dont tell me that what you got and attempted to understand from this video, was that a curve ball and a fast? ball have the same flight trajectory, and that a curve ball is an optical illusion...

what about a cutter? a good one doesnt break until 3/4 of the? way to the plate.
aidan # 5 июня 2012 в 13:43 0
you have to read the description to understand. a curveball? does break, but it travels in a smooth path. There is not a sudden break

Duuuuuuh guys does a fastball go? forwards????? lol idiots

...a "short circuit" occurs where the brain briefly loses track not? only of the ball but of time as well. Thus, when the batter "finds" the ball again, the brain doesn't realize that time has passed making it appear as though the ball has moved more than it should.

A curveball? that is as bad as that one won't curve

Look at Justin? Verlander's curve than tell me more reasons

so if it starts up and ends up down it didnt curve... itsjust how when you see pigs fly they dont really? walk they fly daa i see what you meen now

If i bunt and that pitcher throws me a curve and it starts perfectly at that bat and i "think it curves" and it doesnt hit the bat... are u telling me it actually hit the bat and i? entered a new universe or sometin?

thats? right it dosent curve
tpund # 8 августа 2012 в 01:55 0
I've seen a ball heading straight at someones head wind up in the glove? in the strike zone. I'd say it curved.

I don't really understand how? his basic thesis answers the question. The question is not, "Why does a curveball appear to curve TO A BATTER?" His explanation doesn't address why it appears to curve to a spectator. I've heard this argument before, and it seems bunk.

so is a? fastball really fast?

Watch a curveball in slow motion from any angle you? want...then tell me it doesn't curve
mrmaggot # 18 октября 2012 в 22:17 0
does it curve?!?!?!? uh when it starts out one place it ends up in? another try looking at it from the pitchers veiw it curves ALOT!!

-_- is a fastball really fast? does a? slider really slide?

The prof. says that curve balls do curve but It's the late "break" or sudden change in trajectory that is the illusion. This makes sense from a physics perspective: Newton's? first Law of Motion: "The velocity of a body remains constant unless the body is acted upon by an external force". The only external force acting on the ball is gravity and that's uniform. Gravity won't make it suddenly drop or break.

Did someone understand what the asian guy said?? I was staring at him and didn't understood a single word!

Have these idiots seen a free kick in soccer? Is that? curve just an optical illusion too?
mreminem # 1 ноября 2012 в 09:07 0
I what do they mean?! They should test to see if a curveball really curves from the? catchers point of view, that way theres no variable and the result is striaght forward. I catch for my team and a curveball curves no doubt.

What's next? Does? a knuckleball really move?
montez # 25 ноября 2012 в 15:25 0
no maybe like does a? 4seam stay still

Go up? to bat against a guy with a great curveball and tell me it doesn't curve.

great point.?

not only does the curve ball move with respect to the Magnus effect, so also do the various fast balls also demonstrate this fact. the dynamics? of rotation with respect to the position of the seams in that rotation, as well as the direction of the rotation itself has everything to do with how it will move. whereas a lack of rotation is critical even for such knuckleball pitchers as Wakefield to be successful.

i take it your a? catcher?

Why are they talking to a psychology professor? Any professor of physics or mechanical engineering could explain why the ball curves more sharply (yes, it does) as it approaches the plate.?
captaino # 26 декабря 2012 в 08:05 0
Well, this could be? true, or, it could just actually curve differently like any other projectile with a different spin on it.
oman397 # 26 декабря 2012 в 15:06 0
So? the curveball doesnt really curve?
cybersha # 3 января 2013 в 05:56 0
I think they should have included a professor of physics to explain to the shrink? about the Magnus effect... (there are some physics involved here, you know!) heh
