Geoffrey Lee That is incredible. Gives me so much more respect for archers.

A. Ron Carmichael This is MOSTLY correct. The failure to consider the lateral sliding of the bowstring OFF OF THE FINGERS, which determines which way the arrow is going to flex, and which way the back end of the arrow is going to MOVE, actually altering the initial trajectory (direction of travel) of the point of the arrow, is EVERYTHING about determining whether archer's paradox exists or not. With the compound bow demonstrated, the archer uses a mechanical release that completely ELIMINATES the lateral slide, thus at no point in the arrow release is the arrow aimed OFF of the target as it is when an archer is holding the string with fingers. The paradox is not that the arrow does not "hit" the riser, the paradox is that the arrow IS NEVER POINTED AT THE TARGET BY THE ARCHER WHEN AIMING through a sight. As far as "being smart enough to know which way the nodes are flexing so you can hit the aspirin, just move the archer back 4 feet, changing the distance so he (one of the world's most distinguished and excellent demonstration archers) has to completely readjust his aim. He can do it but it will take him some shots to home back in. THAT IS THE PARADOX: NOT THAT THE ARROW DOESN'T HIT THE RISER/BOW, BUT THAT THE ARROW SHOT IS STARTED OUT AIMED COMPLETELY TO THE SIDE OF THE TARGET, YET STRING SIDESLIP (from the fingertips) CAUSES IT TO BE POINTED DURING A FEW MILLISECONDS DIRECTLY AT THE TARGET. THAT is the paradox. That the shaft flexes in nodal behavior so that the nock and vanes avoid hitting the bow (which his large feathers do NOT do) is a function of TUNING, selecting the right spine as it relates to the archer's release technique, the weight of the bow, the point weight, even the nature of the limbs of the bow and the surface of the archer's finger tab.

Smarter Every Day At 2:45 Byron says "The first thing that happens is the arrow bends from the pressure of the string". He shows a lateral motion while explaining this.

Some notes about this.

We each repeated the experiment 3 times, and got the same results every time. For those of you who might be skeptical, great! The good news is that right circularly prismatic kiddie pools are only $10 and you can do the experiment for yourself at your latitude. There's really no reason you shouldn't do this on your own, so before you criticize how we've done it, I'd strongly encourage you to do it for yourself.

Gordon McGladdery did all of the sound design for the video. We used two songs from other artists (licensed of course). Derek split the first one up so it fades from video to video, and Gordon split the instruments up on the second one. There are violins on one video and percussion on the other for example. It's really neat.


The neat earth animation at the beginning and the synchronizing timer was made by Michael Hannah of http://eisenfeuer.com/. He also made still images of the earth from the top and the bottom.

There was a study performed at MIT years ago (http://web.mit.edu/hml/ncfmf/09VOR.pdf) that explained the physics involved. We repeated some of these demonstrations, but on opposite sides of the globe…and in a way that can be easily understood.

Tibor Schiemann Guys, I know my comment is a bit late, but this rocked! Just the idea of producing two perfectly synced videos from both hemispheres is awesome, not even mentioning the perfect execution or fun you always manage to convey to your audience. I'm glad I'm supporting you - keep up the great work!

Maarten Daalder What is also amazing is that the Dragon capsule was sending telemetry after the breakup. It was suggested that if it had been the manned Dragon 2 capsule on top of the Falcon the humans inside could have opened the parachute and survive the explosion.

Several of my friends have asked me if it was worth it, and I said yes. Every single one came back to me and agreed after the fact. http://www.harrys.com/  Promo code: SMARTER

Earl D Yates Thanks Destin! While I hope that these Scientists are able to find a way to stop the spread of this disease, there are some far reaching implications. This is the first time that I've ever heard of a cancer that is contagious. If a strain of cancer can become communicable among Tasmanian Devils, there is a possibility that some strain of cancer could mutate and become contagious between humans. So, helping to find a cure for these rare critters may in turn, help to prevent a similar outbreak among the human species.

Seeing that moving average visualized and graphed and applying a POV video effect on that high-speed footage finally brought to light the illusion makers were exploiting all these years :D
