- track material is easy to work with and cheap. it is called shelf bracket tracks or shelf uprights. I have seen various hardware stores and building supply stores carry it, one company that makes it is Rubbermaid. E5 shelf upright. available at Home Depot, Last time I checked, Lowes does not carry it

Introduction song. is an Apple jingle found in the iMovie media files, the title is called "catwalk, medium"

One last note, I've had some comments on me mispronouncing height as heighth. My possible responses:
1. sometimes I get nervous in front of the camera and have moments where my brain shuts down.
2. We grew up pronouncing it that way.
3. We all make mistakes.....but is it really a mistake ?
4.. Merriam Webster dictionary to my rescue- Heighth- expressed as a dialectal variant of the word height. Part that rises or extends upwards, the highest part
Chances of getting a million views: very slim
13 million people and counting: We got u bro
Nice
So in reality his chances of getting just 1m views was indeed very slim.
I was thinking... dang, Bruce, you did get 260,000... and then I realized that is the video 'likes'!!!
@@MrVexedviperyeah chances of getting 1,000,000 sharp at the point when youtube ends are really very slim)
Yes, i said youtube ends, no endless travels
Ofc 11m
I swear I learn more at 3am than at school
For real
Bro CZcams is fucking crazy
🤔 lol 2:19 Am for me, you never lied 😂😂😂
Fr😂
This video explains only one formula from mechanics, which teachers just right on the blackboard and let them remain without explanation
The reason that these videos are often more engaging and interesting than school is because this is a CZcams video and they have to make it interesting for you to keep watching but at school they can make it as boring as they want and you have to keep watching
And also the fast cuts to the action, teachers don’t gotta walk over to another table or something.
Editing is time travel
It really depends on the teacher. I had many science teachers, the ones I learned the most from were the ones who were more engaging and hands-on like this teacher. A lazy teacher will get bad results no matter the subject.
The telling difference is that you are not FORCED to watch this.
You are not TESTED after watching.
You are not subsequently RANKED according to your ability.
It’s all mental
In school you think “school boring”
In CZcams you think “ooooo youtubeee”

Hahaha you are like me. I even read fiction novels when I have an exam or simply just another subject. It works for me, it prevents me from having exam anxiety. I have always done better when I do that than when I keep studying.

I honestly wish my physics teacher was this enthusiastic about teaching us physics. I’ve learned way more from this vid than I do in class. It’s sad.
My physics teacher is amazing
I am having the same story ...
I even don't ask anything from her...becuz I ask something else and she tells something else.....
It's sad too...

What did you learn?
Basically, idk what you learned, this guy just put balls on ramps and says : "see what happen here? They arrive at the same time" but he never gives the reason why, I mean he doesn't justify it with a scientific proof
He's the reason why there still new scientists in the wrold. Need more teachers like Bruce to enlighten students to learn and fire those who is just a pay cheque
When science class and woodwork combine their powers, it turns out you get a pretty fun class.
I'm mad at my old high school for not using similar methods when I was there. This turned a boring science/math discussion into a fun and mesmerising learning experience.
Probably the only CZcams video that has added something useful to my life
Skrillz_ 14th the jiggly cake video was useful
and what about jake paul's rap
yeah lol
Did it really tho or are you just having a good time with no real thought like me
You’re looking at the wrong videos
"How do the balls roll at different lengths but touch the wall at the same time?"
"Mitochondria is the powerhouse of the cell."
Oh jesus christ 😂😂😂😂😂 hahahahahahaha your the funniest fool i've seen
No thats not the answer its (some nerd stuff i dont know)
And other stuff
R/woooosh
@Sonic ASMRummmm what do you mean?
@Poonis Monke LMAOOO put that shit on r/youngpeopleyoutube
Whenever I see people like this I realize that I didn’t have one single passionate or enthusiastic teacher.
Physics is so cool. I wish I had this guy as a teacher.
My love for physics only blossomed in adulthood.
Perfectly balanced, as all things should be.
Scorpionoxide this made me laugh. Lol.
Well, the probability track didn't work, but it's because he got more views than expected. So, a soul for a soul.
This does bring a smile to my face.
There are 4.8k dislikes and 4.8k comments
You're the type of teacher everyone deserves but sadly anyone gets
Sadly nobody* gets
Sorry, I had to correct that one.
I totally agree, btw.
Dude I’d kill to o have him as a good physics teacher
1. Kill his whole town except for him.
2. Plant the idea of moving to your town.

I'm a cab driver and these experiments only prove my Theory..."The shortest route isn't necessary the quickest"😆😆🍀
The biggest tip is the shortest route.
No lmao, because these balls are only animated by gravity, while your cab is animated by your engine, and while ofc gravity still has effect on it, it doesn't changes your cab speed. What I mean is that wether you go up or down, you'll still go at 50MPH, and you could even go faster on a straight line w/ no ups and downs becuz these wouldn't "disturb" you.
@@xxneweraxx7422 It was a joke, and i think he meant the shortest route sometimes takes longer because of traffic and crossroads etc.
@@wamiqulislam Oh, i ain't sure about that but maybe
@@xxneweraxx7422 I can't understand why someone had to explain you that it was a joke, and he's absolutely right about it.
He seems very passionate about what he does.. you can hear the excitement in his voice when he speaks. I love that for him
Am I the only one who thinks it's so satisfying to watch the ball roll back and fourth on the track?
Well.. I guess everything works except the probability track..
It worked flawlessly. Probability math can be even less intuitive than physics math.
Nope, everything works except your understanding of probability
Yep I guess so
Everything works except sense of humor, it seems : p
R/whooosh
School is never this interesting
Virtual school is never this interesting
But watching physics on CZcams is fascinating for some reason.
Why don't you have moustache,🧔🧐
It's because these videos are easily digestible pop-science that require no studying, math or understanding to watch
I swear I see you everywhere

Guess what? Now he is :)
Genuinely wish he was taking my physics class

[EL] Megalomaniac Well because science is what it's normally referred to in elem/middle school. He does physics from what I'd assume which is normally a highschool/college level class.
because Bill Nye had a better production team
Gosh I love just finding random educational videos on my recommended page. It’s the best
My 8 year old daughter, 7 yr old son, 5 year old son, and 3 year old twin boys SAT STILL FOR FIVE WHOLE MINUTES! Thank you for the excellent lesson and a moment's peace 🙏💎💝 10+ bonus points for no music! 💗 They're binge watching your channel now 👏
Wow, glad it hear it
Will this video get 1M views? The chances are very slim.
Gets 1M in a week.
Edit: 3M in a year.
Edit: 14M and counting: We got u bro
Killer Kai, I know why he said 1m is very slim because he didn't get 1m view, he got 2m view
3.1M
Proof his science was wrong. Let's move on. He is a hoax.
@@roshlouis8767 youre kidding right?
Aheckinloser whoosh
Why couldn't I get the cool teachers like this
Cuz real teachers like this live in the net
This guy’s probably retired. Takes a long time to be a good teacher, most of them dont last that long.
up
Because you're just one of millions of students through the school system in the last few decades, and teachers like this are few and far between.
Zoon Geralt yeah like you were a saint🤣
Hi! Altough i study mechanics and phisics all the day 7/7 (i'm a mechanical engineering student), and the experiments that you do look so simple there's a lot to learn from this video! Very good content!
*”Will I get a million views?”*
Ball: not likely
CZcams: 11. take it or leave it
He doesn’t have 11 views though
kid ∆
@@smirkykiller9486 he means 11 million
so this just randomly popped up in everyones recommended right?
Alex Tv pretty much
Not the first time...
Luckily
Yes
For the 3rd time
"My chances are very slim"
Gets 6.6 million views
My nan abuses me 7 million *
Now it is 7.7 lol
Still, that's not 1 million.
The prediction was still correct
8 million
You can tell this guy likes his job. Probably a good physics/science teacher. Keep up the good work my man.
I am now inspired and I have decided I wanted to build some of these for myself now. They are too satisfying to not see in person. Only problem I don’t have the tools lol
Your chances were slim, but you pushed through it!
I guess he suspected he was on the right track.
Lol
cool stuff !........your students are lucky to have a teacher like you............by far the brachistochrone is the most interesting ramp of the collection imo......& worthy of a vid of its own.
He doesn't have a brachistochrone
All circular tracks work like that; he explained in the video
yes he does........but he didn't explain it at all in this vid..........& no, circular(arcs) tracks don't have that property........its ONLY the "trace" of a cycloid (half brachistochrone or tautochrone) that has the property of equal times for any/all displacement distances as well as being the overall "fastest" path.......btw the circular path of a pendulum actually isn't isochronous(Galileo Vs. Bernoulli & Huygens I think) ........but for "small angles"(arcs) that discrepancy is typically negligible.......btw if that track is just an arc then its just that the difference(in time) must be in like only mili seconds at that scale & you just can't notice it........just how the cycloid trace looks quite similar to an arc(only a subtle visual difference)....but I HIGHLY doubt that(though I never did a physical comparison experiment nor even made my own tracks)....but even if that is the case its an injustice not to mention cycloid traces/curves. ....but in any case its all quite interesting & non-intuitive......which is why I said it deserves its own video.
www.scitechantiques.com/cycloidhtml/
en.wikipedia.org/wiki/Tautochrone_curve
en.wikipedia.org/wiki/Brachistochrone_curve
www.geogebra.org/m/FEj4yQBH
& it never hurts to ask either......Bruce yeany ........any more info about the track at 1:45 ?
realcygnus I'm pretty sure he uses the arc track, and didn't mention the negligible difference you mentioned. His track doesn't look like a brachistochrone, but I may be wrong.
thats fine..... it ain't no thing at all.....if we learn something/anything then "its all good"! right ?......I'm quite certain(though only like 90+%ish ?)....... & kinda just prompting him to expand on it, even if only slightly.......it could be that the difference in this(arc Vs. cycliod trace track) case is also "negligible" at perhaps small scales? (like a pendulum not being truly isochronous but "close enough" @ "small" angles to make clocks).......in which case I'm technically wrong..... but the FACT is that its cycloid traces that "precisely" have such(as demonstrated) properties & warranted mentioning imo....also his main audience is likely grade or high school & so he may have just left it "open" intentionally so as not to confuse anyone.....whats really amazing is that Newton(& others) Nailed the exact mathematical descriptions/solutions to such things hundreds of years ago !....& that we now have the nearly "instant" & abundant resources that we do.
realcygnus I overlaied the arc and circular trace curves and they were very similar
Teachers like him are the reason I like science and math
The coolest science teacher ever
4:45 *IF YOU HAVE UP & DOWNS IN LIFE YOU WILL REACH GOAL FASTER*
i have only downs in my life... *time to get some ups*
That makes no sense
You will reach the end faster. Sorry.
See 4:28, 4:45, 5:00... More the number of ups and downs, lesser is the speed.
Surprisingly motivational but I am lacking in "ups." Time to get a new delivery service
You make remarkably good content!
thanks John
I wish I had you as my physics teacher in High School back in the late 80's.
This wasn’t a recommendation, I actually searched for this video 🤙🏽
Perfect it just hit a million views!!!
Now its 2M
Chances are slim
"Who cares?!"
Now it’s 2.8
Well, his ball prediction was correct. He didn’t get a million views. He got 7. (Million)
Incorrect, at one point he did have 1 million views 😈
@@shadic187 yes but now he doesnt
Abyssal Slim chances doesn’t mean no chance

Very cool. Would watch again.
I just watched a dude swing apples and play with his balls, why aren't I sleeping?!
Very poor choice of words
Yeah
That sounded so wrong
Wow you guys are so right, his comment sounded really wrong! That's really funny, he should've made a joke about it.
“Chances are slim of getting 1m views” *proceeds to get almost 10m views*
Well... It's not wrong, he did not get million views, he got 10 million
11m now.
Slim aint impossible
@@thegermanbasket732 technically he did get 1 million views at some point

This guy was my teacher. He retired but still substitutes occassionally.
Unfortunately not me

@Jason Hess lucky
Your prediction track needs some work.
Jesse Harrison it said slim chances, not impossible
He needs to make the brachistochrone, if I spelled that right.

I wish i had teachers like you growing up! Very smart man. Keep up the good work! - saludos desde Palmdale CA
Sir. This was informational and fun to listen too. I wish I had a teacher like you
oh my godness, wish a had a professor with these tools, visualize the content makes it easier, i loved your video!
I wish this video would get a million views and cause this channel to get even better. what would be amazing is if this channel got big enough for Bruce to stop teaching at a school and become a youtube teacher. If we could get daily physics videos I'd love it. Kinda be like Smarter Everyday (who I have been subbed to since he had 7k subs) but with a Steve Spangler upload frequency. I don't like Steve Spangler though. All he does is take ideas from other peoples videos.
i feel like he really enjoys teaching though - which is wonderful
Thanks, x9x9x9x9x9, I do enjoy doing youtube and I realize that my videos are a bit simple compared to the big numbers guys, but my first thoughts are that I still love the classroom. This is my 41st year of teaching and hope to do at least one more, after that we'll see what can happen. I'm happy to share my ideas with anyone that has an interest in science and have had several smaller channels contact me and ask before using my information or parts of my video in theirs. Steve is actually the only big numbers guy on youtube that has shown the same courtesy. I know he's had a number of TV programs on science and has one now called DIY SCI. It should be interesting, my school students entered a contest that his television program is hosting on Newton's 3rd law, they should announce the winners in a week or two. we'll see what happens. I appreciate your comments and thanks for watching, I've gotten off to a slow start with videos this year but I think I have a good set of ideas that I want to tackle and am trying to get back to posting regularly again.
Simple is good!
As you are a teacher, I am pretty sure I do not need to tell you tht first one needs to learn to walk and then he can learn how to run. In fact all those "simple" demonstrations remind me on my own physics class when I was at an age of 12 and had the big luck of having a teacher demonstrating things to us instead of just writing formulas on a blackboard. No text book can replace the experience of hearing - or better said "not hearing" - a ringing alarm clock (you know the old classical ones) in a glas compartment when air gets pumped out. Simple? For todays standards: yes. But it is something, you will never forget.
But your taking ideas from gallaios book so your no better. Just kidding!
x9x9x9x9x9 15% there
The track at 1:42 is really cool. Educational yes! I would not have guessed that result.
It's called a brachistochrone, it's the perfect balance between horizontal and vertical direction to achieve the fastest diagonal distance. It will beat any other shape where the end point is below and to the left or right of the start point, this site has a good animation for it www.geogebra.org/m/FEj4yQBH
SplatterFrog Here's a Vsauce video (with adam savage) about it czcams.com/video/skvnj67YGmw/video.html
Only works with that shape, which happens to match the shape of a pendulum
You sparked my curiosity, Thanks 👍🏼

What the hell is your profile picture!?
3:09
In 4 years of physics class the only "experiment" my professor did in high school is break a chalk in two pieces and drop it on floor to show they hit the ground at same time. He simply didn't care to teach us anything and he worked in that school for decades and nobody cared he did a lousy job. It explains the whole failure my country is.
Literally everything you need is explained and drawn out in the textbook.
The concept In This video is literally something you learn at age 13/14 in the UK before you even split the sciences into the 3 usual disciplines.
The best bit about science is the theory, this practical demonstration, while cool, is pretty unnecessary to get the point across.
@@alexx_tv2362 but the point of this useless experiments as you called it, is to get the students engage.

It's pretty accurate compared to the videos with the most views on CZcams, just saying.
