Convinced despite naysayers: human finger beats sound!

[Pyrotex]

That makes you a real SICKO mister! ..the odd man left out in the dark. Good stinkin' riddance to pathetic ignorant sanctimonious self-absorbed stilted pedant jerks!

Sorry, hefner, but you got it backwards. Good riddance to YOU. Your ignorance of math, science, adult behavior, polite manners, and reality in general makes YOU the odd "boy" out.

 

Clean up your act or get kicked out.

As for your arithmetic rebuttal, I'll only venture that yes, you can and do achieve the necessary force and speed. I mean, isn't it obvious now that Jab2 has brought up the "snapping shrimp"?? I had never heard of the creatures, but if it's a known fact that they break the sound barrier with their muscular twitch, then it's not at all unreasonable to think we too can achieve this. Obviously the shrimp uses its twitch for propulsion thru the water, and it would only snap when caught and brought up in a net. Then its twitch becomes a frantic one indeed.

 

Here's a page dealing with the snapping shrimp.

 

It states that the tip of the claws move at 200m/s. The speed of sound is about 1497m/s, in water. So, the speed of sound is not broken by the snapping shrimp. In fact, it would have to snap about 7 times faster to achieve the feat.

I can make the finger 'snap' noise by quickly moving my fingers to impact the thumb pad and eliminating the fingers-together action altogether. Video to follow at a turtle's pace. Try it yourselves. :lol:

Wow, such a display of maturity :lol:

Since you now have achieved the conflict you sought in this post, way not go and think of a new challenge to amuse us? The source of the noise when an inflated ego is deflated come to mind.:(

I just wanted to interject that though Pyrotex's math is theoretically sound, it ignores the math of the microsystems. As a whole, the finger, might not achieve faster than sound velocity but I'm willing to bet that portions of it might approach that acceleration.

 

Also I would think that friction would have to do with the resulting sound. A mechanic, I imagine, that would work something like the Booming Dunes.

Microsystems? What is that? Here are the systems at play:

Look up the differences among deflagration, explosion, and shock. Clapped hands or snapped fingers are explosions. A whip crack is a shock. A well-made whip tapers toward its working end. The momentum must be directed, accumulated, then pulse-discharged.

 

As to friction, where do you mean? At the point of impact, or the pre-snap-sound-friction of a finger rubbing the thumb? If the latter, I made the snap sound without rubbing any fingers to thumb in the posted video. YouTube - no snap finger snap http://www.youtube.com/watch?v=xcbRPAf36X0

 

The echo effect was incidental feedback; my bad. :D Anyway, the point is that my scientific evidence through experiment contradicts hef's original complaint/grunt/whine/what-have-you, while affirming other posters affirmation that it is the finger striking the ball of the thumb that makes the snap. Yada yap tap. :hihi:

To further contradict the original hypothesis one could show that the sound made by the snapping fingers - without impact, is just a dry rubbing sound

Excellent point! We can use a finger from one hand and a thumb from the other. This makes all else equal. Where you goin' with all that bright J? :confused:

Why thankyou sir - I think we can safely say this one has been busted wide open

Is it only me, or has any one else had a little cognitive dissonance at the still image of Turtle apparently simultaneously giving us a thumbs-up while shooting us the bird? Not that this might not epitomize the spirit of hypography ... :confused:

:eek: I did notice that

 

and I thought it was meant to be a random still from the footage

:cup: when i read Craigs' post and looked at the image i almost choked on my sandwich laughing. (I know; dangling participle!:eek::eek:) even funnier given the thread title.

 

the still selected from a video on YouTube is as you say J, more or less random from near the middle of any given clip.

 

once i realized that the Universe is laughing behind our backs, i deduced that the Universe has a sense of humor. we can take this image as a manifestation of the serendipitous grace of that humor. i can only wonder if the French would find it funny. Mon dieu.:doh: :D
