Education combined with play is always the best way to interact, so happy you do what you do!

This is great! Lots of potential for different games trying to hit targets around corners. Easy for kids to have fun and learn at the same time.

I found out self replicating machines somewhat impossible maybe completely impossible because even they themselves need "dna" or "rna" coding imbedded into the machine (and the tools resources and programs to run it) en.m.wikipedia.org/wiki/Self-replicating_machine A self-replicating machine is an artificial self-replicating system that relies on conventional large-scale technology and automation. Although suggested more than 70 years ago no self-replicating machine has been seen until today.[citation needed] Certain idiosyncratic terms are occasionally found in the literature. For example, the term clanking replicator was once used by Drexler[5] to distinguish macroscale replicating systems from the microscopic nanorobots or "assemblers" that nanotechnology may make possible, but the term is informal and is rarely used by others in popular or technical discussions. Replicators have also been called "von Neumann machines" after John von Neumann, who first rigorously studied the idea. However, the term "von Neumann machine" is less specific and also refers to a completely unrelated computer architecture that von Neumann proposed and so its use is discouraged where accuracy is important.[1] Von Neumann himself used the term universal constructor to describe such self-replicating machines.

The magnus effect is used in most ball sports; baseball pitch, volleyball spike/serve, European handball, table tennis, tennis, etc. Alot of these sports or rather techniques used in them is centred completely around the magnus effect via putting spin on the ball. Even games you play in high school such as dodgeball can take advantage of the effect.

We need more teachers like this guy

My brothers and I had these growing up. They were so much fun. I wonder if Walmart still sells something similar to what we had 20+ years ago.

That's really fun! Two straight sticks as wide as possible for the ball should create plenty of overrotation, and thus the most spin / best curve possible 🙂

Finally .. the algorithm has brought me something educational.

Such kind of teacher make you love Physics

Nicely done. Really grateful for the blue striping to help see the ball in motion. The high speed camera was really useful here too! Like always, I will be stealing this and incorporating it into my class instruction. Odds are huge you have taught more science teachers how to do hands on experiments than any college professor - but it would still be good if you were tied with a few, but I am not holding my breath for it. Thanks for sharing and helping us all.

That’s wicked Mr. Wizard. This man really reminds me of Mr. Wizard from Nickelodeon. Very cool.

Reminded me of those Toobees or flying soda cans you can make by cutting the ends off and the length somewhat, how they curve when tossed with a spin.

Well done.

Many years ago there were mass produced devices that did this. Unless he was the inventor, devices for this effect have already been made. I played with them all the time.

Very nice.

BB guns have a little friction part in the barrel that puts a spin on it to keep altitude longer. They called it hopup.

Dude!! You got alotta balls 😄

I used to throw marbles with a pipe with a movement like this. It's so powerful it could probably kill. I even practiced shooting it and it would sometimes put holes in plywood. It can reach about 100m-250m but accuracy is very low since it still spins and curved sometimes, even though it's small and heavy. But accuracy is good enough in about 20m range. It is one of the most dangerous things I've done and came up with as a kid. Marbles would sometime just shatter on impact.

I think a prong carefully matched for the diameter of the ball could send a ball flying in one direct for the person to be able to catch in the other direction, like a right handed person propelled a ball leftwards, as hard they could, I reckon they could catch it on their right side. There might be other factors that could help but a little bit of wind assistance would help a great deal tho and maybe being a Jai alai player would help.

Great 👌

Brilliant

He hits the window 😂, that’s awesome

A Hop-Up-System uses this effect for the small round plastic bullets in soft-air-guns.

I wish I a teacher like this guy at school maybe would have had an interest in physics and engineering a lot sooner than I did develop that interest 🙂

There do exist ships and aircraft that use the Magnus effect for propulsion and lift, respectively. In these instances, they're known as Flettner rotors.

Excellent video...Is the Magnus effect the reason for swing balls in cricket? Also would like to know what kind of effect does shining the cricket ball just on one side create? Does differential sides in a projectile (cricket ball) create more pronounced Magnus effect (swing)?

@YeanyScience

3 жыл бұрын

I didn't add it to this video but thought about doing one on this, the Magnus effect and the knuckle ball, one with no spin, however we need a better camera to capture it. We have played around with the design similar to that of the cricket ball, smooth on half of it and rough on the other half, in this case the rough side has more friction as it passes through the air, the greater friction against the air pushes it towards the smoother side. My understanding is that this is not considered an example of the Magnus Effect. However, if the ball is thrown with a spin around the correct axis, the ball can curve due to the rough side friction and the Magnus Effect at the same time, with a sideways and upwards movement. I believe that if a baseball is oriented correctly, it can also curve in the same manner as the cricket ball.

Good question, I don't have an answer for you, perhaps someone else will, one factor we did test was that does affect the speed would be the length of the basket. Up to a certain length, making it too long then becomes harder to control and swing.

When I had middle school students investigate this, we combined using throwing balls with the cup flyers and the Flettner rotor. Changing the mass was easy, as was the surface texture. Changing the amount the surface area had to keep the same mass, air speed (measured with an anemometer) in some cases was simply firing into a wind or changing the nozzle distance away from the rotor, also changed the Flettner rotor spin rate. We could change the spin rate on throwing the balls by how smooth the paddles were, adding rubber to the paddle increased the friction the most, and smooth PVC pipe had the least. Students also made sling shot type of contraptions to throw the ball without spin.

You can spin the ball with your fingers while throwing
