The mysterious isochronous curve

[@Eis_Bear]

The isochronous curve was also an important discovery for the advance in timekeeping, Christiaan Huygens invented the cycloid pendulum which doesn't simply travel part of a circle but rather travels in an isochronous curve thus keeping the same timing regardless of momentum.

[@nicholkid]

brilliant

[@bobweiram6321]

I was thinking about a practical application for the isochronous curve in particle accelerators after watching the video. Did a quick Google search and found out some cyclotrons already use it in their design. Damn! They beat me to it.

[@WadeWilsonDP]

@Arcadetron Racing A pendulum is the thing you see in a grandfather clock that swings back and forth. A clock is a mechanical device used to keep track of time based on the rotation of the Earth. It takes approximately 24 hours for the Earth to make a full rotation and we divide this up into 2 12 hour segments. A typical clock has 12 numbers on it, depicting the 12 hours of each half of the day. We divide these up into 60 segments that we call "minutes" to keep track of shorter lengths of time.

We went through this demonstration/lesson in Physics in High School. It was one of those lessons that I will always remember as our teacher also explained how, based on that curve and how it graphs out over multiple revolutions and how it relates to distance and speed, there is a point where the part of the tire touching the ground is not going anywhere, yet your vehicle is moving forward. This lesson and lessons on infinity.... those were some of my favorites. My teacher took the point on a ruler and asked us to divide that by 2, then that by 2, then that by 2, etc. We obviously kept getting smaller and smaller numbers but soon realized that no matter how many times you divide the space on a ruler between 1" and 0 that you will never get to 0. You could divide the number in half for the rest of your life and never get to 0. So does that mean that there is an infinite amount of space between all objects, all matter?

[@cpruns4501]

What I took from this was proof and the fact there is a mathematical evidence of a theory I have had for some time now. When you start something new come out hot (or fast). The reason (of course) the ball on the curve hits the "finish line" first is it comes out fast! So, when you are taking on a task come out fast and get some momentum going. People I have worked with (or done anything with) in the past will say "Slow and steady wins the race" but as we can see here, that is not the case. the next time you take on a project come in guns blazing and get the first 20% of it done with all your effort. Once that momentum is going it's much easier to get the project done faster (overall) even if you can't maintain that speed the whole way though. Great video.

So, while the shortest distance between two points might be a straight line, I guess the shortest time between those two same points is an isochronous curve. Quite interesting indeed.

Science FTW!

[@nerd1000ify]

The shortest course between two points on the globe is a 'great circle' route, which basically means you follow a path across the globe's surface that is part of a circle whose center is at the center of the planet. Such a path is by necessity curved.

[@LogicNotDogma]

Only the shortest time under the influence of gravity, if you were driving a car between two points then a straight path would take less time than (any sort of) curved path

[@Jamil1989]

I was going to say: momentum has a part to play. And Mr. Brian said gravity.

[@disruptivegarage]

the shortest distance between 2 points is a great circle. the reason sometimes a straight line is shorter is because of the type of chart you use, it varies with the type of projection used. and if you want to reach the middle point of the test this guy performed with the bearings as soon as possible you have to trade the potential energy of the bearing asap(straight down) followed by a smal radius curve to convert the vertical motion to horizontal motion. great circles are curved on a mercator chart and straight on a globe.

Thanks. Curiosity Show was a national science program featuring Dr Rob Morrison and Dr Deane Hutton. It was made in Adelaide, South Australia and screened nationally in Australia as well as in Europe, Asia and Australasia (14 countries and dubbed in German for Europe) from 1972-1990. Deane and Rob intentionally used everyday items around the house (like old rusty cans) so that people could repeat the demonstrations with materials they had to hand. In 1984 Curiosity Show won the Prix Jeunesse International, the world's top award for TV programs for young people. Rob and Deane are steadily uploading segments at kzbin.info Why not subscribe?

The ball bearing dropped with more force from the curve then from the straight line. The ball bearing hard to exert the friction being produced by microgravity. The ball bearing dropped downward resulting in less friction and quicker exceloration of the ball bearing.

[@timothyrepp4259]

Turns out the fastest route between two points isn’t a straight line.It’s an isochronous curve.

[@lifes2short]

Tell that to my physics teacher 🤣 Lol in a downward/gravity driven situation. Then yes, on the horizontal axis, as we move as humans then no lol

[@tituslafrombois1164]

Well, "fastest" in the sense of least distance traveled, yes, straight line is the answer. The ball bearing on the curve only got there faster because it started at a much stepper angle and so built up momentum quicker.

[@hangukhiphop]

assuming there's a force like gravity accelerating the object in only one dimension edit: that's actually the brachistochrone, which is a similar curve in the cycloid family the isochronous also belongs to

Today, such an educational program would be made with computer graphics. It would still be as useful for a demonstration, but there is something about watching real cardboard and ball bearings. You are watching reality, not an animation of a claim. It is real and easier to remember, so more effective for education.

This curve holds a lot of secrets. The area of the enclosed cycloid (segment) is three times the area of the circle used to create it, and the length of the curve is four times the diameter of the circle. So the Pi value of a rolling circle is _four_ . You can create this cycloid by tilting a circle 57.518 degrees from the vertical, and then photograph the top half of the tilted circle. It's the only isochronous curve. Somehow it seems to be aware that it is supposed to be a circle.There's something in this, but I don't know what. .

Reminds me of the old saying: “Anyone can build a bridge, but only an engineer can build a bridge that just about stands.”

[@NYCZ31]

This seems pretty common even in today’s era of computers. John Roebling, who designed the Brooklyn Bridge, did all the math and then multiplied it by 6 to make sure everything was strong enough. This turned out to be prescient because a manufacturing flaw in the suspension cables meant they weren’t as strong as designed, but Roebling found that even with the flawed cables everything would be four times the strength needed, which was still considered sufficient. 138 years later the bridge still stands proudly.

[@Mikowmer]

@@NYCZ31 Yep. Safety Factor. Protects against damage and manufacturing faults. Very useful.

[@littlecabininthebigwoods5720]

It’s simple. The materials were tested until they broke and given a value. If something is designed to withstand only it’s max, it would break. It’s like we find out what the maximum weight you can lift is and then tell you to hold it all day. You better get three times as strong or use a weight that’s 3 times less if you don’t want it to slip from your hands.
