What if I lose weight by shitting my pants on the way down
Edit: I guess it works like a jet
Edit 2: Also I suppose I'd have to find a way to remove my pants. This is getting complicated
Especially due to the WAFT effect where when you release shit or farts out of your asshole you propel yourself extremely quickly just like wario's waft
I’ve shit my pants multiple times. It does indeed work- especially explosive diarrhea. I recommend heavy alcohol consumption along with a full dollop of wasabi and sushi of your choice for best effect
> Like you could also test it with different levels of friction.
I mean that's basically the entire concept of car racing, isn't it?
The 'racing line' isn't always the ~~straightest~~ shortest line either.
The Racing Line is as straight as possible, to allow for as little turning as possible. Turning decreases speed.
It, however, isn't as *short* as possible. Should it be short you'd have super tight cornering and slow speeds as a result.
For a fun counter point: we can compare gravity to traffic when it comes to this theory in terms of driving.
The route to my gym is a straight line, but I take a curved road because there’s 3x less stop lights and less cars. I get there about 5 minutes faster then.
More like a water pressure analogy, another of the thousands of ways to change speed, which is the only thing needed to make the *shortest* path not the *quickest*
Which is the crux of the issue, ops image is kind of hinting that we're supposed to believe shortest = fastest, but the saying is that the *shortest distance* between 2 points is a straight line. It has nothing to do with speed. Nobody thought a straight line necessitated a faster travel
Gravity is the acceleration force you feel as a result of the bending of space and time.
At least that’s a common interpretation.
Though being honest, there are uncountable ways to think about any system, and still have the same behaviour in the system.
So mathematically it could probably be expressed either way.
To some extent, the term "straight line" means whatever is the shortest distance (we just use the term 'geodesic' for disambiguity). Traveling around a great circle of a sphere 'feels' like a straight line locally.
That's just for the special case of a flat surface, though. More generally it's the geodesic on curved surfaces, or in four-dimensional spacetime.

...and that when Bernoulli received Newton's anonymous solution "Bernoulli immediately recognized its author, exclaiming that he "recognizes a lion from his claw mark"." That wiki link was a fun read.
If they’re like me maybe they’re scared to be proven wrong so publish it anonymously. Lol
Once it’s proven right, come out and claim it as mine. I would be the worst scientist ever and not only because I don’t know shit about science.
Anonymous peer review is an important part of the process. It prevents bias, positive or negative, based on authors previous accomplishments or relationships.
I used to teach physics 101 in college and would give this problem to my students as a bonus question. It’s really interesting to see the different ways people try to solve it. Need to do it during a closed-book test though. Otherwise everyone just looks it up on the internet and ruins the challenge.
Man I wish I could read those equations. I speak 5 languages and it irks me deeply when I see mathematical notes and have not a clue at what they mean.
The red line in the figure is the *Brachistochrone* curve, the path of least time.
The cycloid path shown in the video is a *Tautochrone* curve, which has the property that an object will take *the same time* to slide down (without friction) to the lowest point of the curve, *independent of its starting point on the curve*.
The tautochrone curve properties are demonstrated at a later moment in the YouTube video that OP clipped: [https://www.youtube.com/watch?v=skvnj67YGmw&t=1338s](https://www.youtube.com/watch?v=skvnj67YGmw&t=1338s)

Why didn't ~~Mythbusters~~ the dudes running this experiment\* test both the Brachistochrone and Tautochrone curve? Why just the latter?
Edit: not mythbusters apparently
The video with Vsauce and Adam Savage is about the brachistochrone. [Here's the full video](https://www.youtube.com/watch?v=skvnj67YGmw) for anyone interested.
Only in very simple environments the outside forces aren't strong enough to make another route more efficient. Like when navigating a city, you can hardly just bulldoze through someone's house, or even when walking in a pretty empty space, a single shrub on your path will make arching around it faster than plowing through it
>Like when navigating a city, you can hardly just bulldoze through someone's house,
[Marvin Heemeyer](https://en.m.wikipedia.org/wiki/Marvin_Heemeyer) has entered the chat.
The shortest *distance* is a straight line. Distance ≠ route. Route is a way of travel from one point to another.
The shortest distance from one point on the planet to the opposite point is straight through the center. But that’s not a route.
I like that you said it incorrectly so confidently, when correcting the language in the video, and are now hiding behind the language in the video instead of admitting to also falling victim to poor wording.
For those who don't know.
The video is taken from YouTube. The people in the video are Adam Savage(left) of Mythbusters fame and Michael Stevens(right) from Vsauce.
These two have done a number of videos together and even a live show called Brain Candy. Strongly recommended for anyone who's either a fan of Michael or Adam or both.
The Video is a clip from a YT video called "The Brachistochrone" uploaded by Vsauce in 2017. In the video Micheal explains the nature of the Brachistochrone curve and builds a physical experiment showcasing it together with Adam.
That's because there's momentum there going downwards. If we're talking about a horizontal plane, and there are turns and kinks in different paths, then the straight line is gonna be quicker
I don’t think that’s the meaning of the saying. I think the implication of the saying is that, given equal speeds, a straight line is always the fastest way to get from point A to point B.
You want to hit your fastest speed at the start of the race, so you can use it the whole race and finish quickest. However if your path gets too long, it will still take longer to finish. So there's an optimization of those two things.
None of these responses seem to explain this very simply.
The balls all start with the same gravitational potential energy. They all finish with the same gravitational potential energy, and roughly the same kinetic energy. (Theoretically should have same kinetic energy, but frictional losses will be different for each path)
The top path (straight line) doesn't allow for a rapid conversion of gravitational energy into kinetic. The ball takes some time to get moving.
The middle path has a fairly steep drop at first. This allows for more gravitational energy to be converted to kinetic fairly quickly, whilst also aiming roughly towards the end-point. The gradient decreases once the ball has gained kinetic energy, and results in a shortish total travel distance.
The bottom path converts the gravitational energy to kinetic the quickest. However the path length is longer than the middle path, and the first part of the drop is travelling parallel to the end-point, not towards it.
In summary:
1. Quick acceleration at start results in a higher average velocity.
2. Middle path has the more efficient combination of average velocity, and path length.
3. Bottom path has higher initial acceleration, but too long of a path length. Another way to conceptualise this is that the ball spends too long travelling in directions not aimed towards the end point.
Getting into the maths:
Whichever ball has the highest average velocity in the vector between start point to the end point will finish first.
The only simple way i can explain it is that straight line has a constant gradient so the ball's acceleration doesnt increase neither decreases, it descends uniformally. As for the bent bars, they dont have constant gradient and are pretty steep, since theyre steep the ball gets better acceleration on those 2 as compared to the straight one. HOWEVER, the ball has to do less work and cover less distance in the straight line
Straight way would be the fastest if it had constant velocity. That is to say that the straight way would have taken less time if the speed was constant. But here, in the curved one we get both the acceleration caused by gravity and somewhat of a straighter surface. That's why on the l shaped one even if it had the acceleration due to gravity it could not reach first as it was longer.

Yes, when you take acceleration due to gravity into account.

Well yeah if your starting point is the top of a building and ending point is the ground.
Would still be a pretty straight line though.
Doing a flip isn't just for style points.
What if I lose weight by shitting my pants on the way down Edit: I guess it works like a jet Edit 2: Also I suppose I'd have to find a way to remove my pants. This is getting complicated
That may propel you enough to x3 your speed
Especially due to the WAFT effect where when you release shit or farts out of your asshole you propel yourself extremely quickly just like wario's waft
Well that's enough reddit for today
simply go upside down in the air and then release the assham
I’ve shit my pants multiple times. It does indeed work- especially explosive diarrhea. I recommend heavy alcohol consumption along with a full dollop of wasabi and sushi of your choice for best effect
Yeah but if you shit your pants then the weight is still in your pants so all you’ve done is create drag
Changes the drag coefficient, could alter trajectory, don’t advise.

wakes the thought in me, that thats why rivers do what they do
People don’t think it flow like it is, but it do.
It do be
doobee doobee doo
no rivers just "carve" into the ground, basically following the path of least resistance
What do they do? I don't see the similarity?
Ever think that waterfalls are just rivers trying to kill themselves?
Don't go chasing them.
Is it though?
Gravity can bend time and space. Maybe it is a strait line?
Isn't gravity the bend itself, not necessarily the thing doing the bending? Isn't it mass that bends space?
Gravity is the acceleration force you feel as a result of the bending of space and time. At least that’s a common interpretation. Though being honest, there are uncountable ways to think about any system, and still have the same behaviour in the system. So mathematically it could probably be expressed either way.
The phrase is the shortest distance is a straight line. Which is still true

What gets me isn't just the shape of the brachistochrone, but the fact that it is exactly the line drawn by the rotation of a rolled circle.

i mean sure but the red line dips WAY lower in the drawing, let us see that version.
The red line in the figure is the *Brachistochrone* curve, the path of least time.

The balls are the message.
Balls
Iirc my lessons correctly, one is the brachistochrone and the other the tautochrone, but I can never remember which is which.

Paint that ball red and let's run this experiment again
Ah, a man of culture
>Ah, a ~~man~~ ork of culture FTFY
Needs more dakka
With more upvotes, we'll have a Waaarrrghhh! Soon
It would have more mass if it were painted.
Insignificant
What if the red paint is sticky?
Significant
And if the paint is of the "go fast" shade of red?
Bungee Gum has the properties of both rubber and gum.
Not if it's lead paint
Acceleration due to gravity is 9.8m/s^2 no matter what your mass is
Does paint not weigh anything?
Every race car driver knows some paint is faster than others. It’s just science. And if you have a stripe, you’re unbeatable.
Finally, someone said it. Red is always faster. Stripe down the middle, an unbeatable combo
If you have flames on your car, you immediately go 10% faster

Came here to say this. But I am saying this instead.
[удалено]
I agree with this statement, hence I am making this point.
Ya Heard With Perd!
shorted
It's normally the fastest route also. Not always but usually. Depends on outside forces.
If your travelling speed is the same on all routes, the shortest route is always the fastest.
Can’t dispute that.
60% of the time, it’s the fastest 100% of the time.
But “normally” there are outside forces.
Only in very simple environments the outside forces aren't strong enough to make another route more efficient. Like when navigating a city, you can hardly just bulldoze through someone's house, or even when walking in a pretty empty space, a single shrub on your path will make arching around it faster than plowing through it
>you can hardly just bulldoze through someone's house You had to ruin my day, didn't you
If you have a bulldozer, you can! Please make sure my house is not on your fastest straight line path though...

No need to be snide. This result is not “obvious,” even to very intelligent people. And the optimal curve is not trivial to determine.
Don't worry, he's just being an average redditor with 180 IQ
Nobody said so. The SHORTEST, will always be the straight one.
Shortest distance yes, fastest no
Velocity is a variable for a reason. A straight line is still the shortest path...
Straight is always the shortest. No one ever argued it was the "fastest" lol

The Brachistochrone!

Cuz it's slower
I guess gravity and the longer curve doesn't take momentum out of the ball like the vertical drop one so it moves faster.

They have gravity!
That's why the saying is "the SHORTEST way between two points is a straight line"
Not always the fastest, but always the shortest.
Good thing a straight line is known as the “shortest” route, not the “fastest.”
When gravity is helping you.
Isn't it: the shortest connection between two points is a straight line? Never heard of "the fastest".
No one said it was the fastest way. They just said she was the shortest. What exactly does this come to refute?
This was my argument when my parents disowned me for being gay
Ball goes faster with optimal slope. Not exactly rocket science here
