Thank you so much, I really needed this. We need more people like you and the guys from Crash Course, I thank all of them with the utmost love and appreciation. You are hero's that wear no capes.
I started watching this channel years ago, with John Green... and i cam back to it and i still this channel has one huge problem: The information is REALLY REALLY GOOD, but they give them to you SO FAST that you don't time to process that information. In this video you can see that this girl talks at an average speed but they cut the silence and edit it out. I think thay should tell everything a little bit more natural. Still, really really good channel.
It can sometimes be a problem. But it's one with an easy fix. When you listen to a video on a new topic, click on the frame so it gets focus, and then keep your hand hovered over the spacebar. When they say a thought that is new to you, hit the pause button and take a moment to digest; or go back to repeat if needed. So like, for CC Chemistry, I was pausing the thing pretty constantly. For this one, since transferring colleges made me retake tons of intro physics, I can pretty much just play it in the background and follow along. The great thing about removing all the pauses is than when you've become more comfortable with the topic, you can review the information very quickly and efficiently allowing you to figure out which portions you haven't completely absorbed.
Real talk she kinda goes to fast for u to digest wat she says properly it's like she rushing to read off the teleprompter crash course philosophy phase is much more better but she is good also just goes a lil to fast
This was way too compressed for me too. I’m going to try lowering the speed as well as pausing often. And before that, I’m going to do jumping jacks to get my heart going.
Y'all ever seen that meme with a picture of a dog holding his own leash and the caption is "When the teacher is useless so you have to learn everything on your own." I'm in that situation now and this stuff is really gonna help.
My phys teacher is useless compared to this video. He gives NO EXAMPLE, NO GRAPH AND ONLY THEORY ON WHERE THE FORMULA COME FROM. And then expect us to understand every problem.
++ for making and sharing this crash course - for talking through this without a break (I can press the pause button to take time to reflect but it does make the listening experience any nicer)
Enjoying the series greatly! One criticism on the audio - something about the recording equipment or equalization or encoding is causing her "s" sounds to peak/distort. I've only noticed this in the past few episodes (maybe this one and the one before), but it is definitely consistent at this point. Hurts muh brains.
I don't mean to be rude. I really enjoy Crash Course Physics and all of Crash Course. But I've been watching most of these videos twice. Once to actually refresh my previous learning on the subject and once to go to sleep. It isn't boring, it's her voice. It's not a bad voice but it reminds me of someone I used to be involved with and her voice relaxed me. It's been a long day and a longer night. Keep up the great work.
I have a pair of noise cancelling headphones that I got for travelling on planes. It's fascinating but that signal it makes causes my head to feel SUPER WEIRD! -Nick J.
+CrashCourse Hey do you guys think it would be possible for Shini to talk about her personal experience studying engineering in varsity, if it was difficult to find a job after graduating and what she did to start finding jobs, like this particular one?
I like that at 1:37 there's a wave diagram on top the line of tiny waves on the water. And the tiny waves represent a straight line. Anyways, these vids are really cool. GOOD JOB, CREATE MORE LIKE THESE & OFC... DFTBA! :))
Yaaay! I've been waiting for sound to come up, it's my favourite topic in physics. I'm a musician and music teacher, so I need to be able to explain the science behind sound to my students from time to time ^_^
+Tony Weeks When you reply a plus sign to TH-cam comments, the comment is considered more relevant by TH-cam's algorithms, so more people are able to see it.
I have a question. In the case of constructive superposition, each pulse has an energy of .5×kA^2. It means that the energy in the system is kA^2. But when they superpose, the amplitude becomes 2A. Then the energy in the system is .5×k×(2A)^2=2×kA^2 Where does the extra energy comes from?
This is the best channel for studies I've ever found. Can you please complete this physics series before december, I am planning to complete my full portion before December. it'll help!
That's a REALLY good question. The answer: Yes, there are! However, they are not called "non-traveling waves" they are called "standing waves"! Standing waves are fascinating. Since next week's topic is "Sound" there is a very good chance that standing waves will be covered, as standing waves come up a lot in the world of acoustics.
simpelest way to look at standing waves is to look at the pictures of waves in this video like at 1:39. If the point where the rope moves through the barrier between orange and blue doesn't move to the left or the right it is a standing wave.
At time 1:17, they show 1.5 wavelengths to equal the diameter. What do you think? Is this correct? Should the wavelength be equal to 2 diameters (1 diameter is half of a wavelength)? I know that this isn't related to the rest of the video, but it made me wonder.
To be completely honest, I think waves should be the very first thing to be thaught in any education program, as they are probably the most fundamental thing in the entire universe as we know it.
You should mention what part (s) were confusing so others may try increase the amplitude of your understanding with a little constructive interference. ;)

The moment you watch English physics videos for your German finals, so you learn English and physics at the same time xD
You condensed a topic in 7 minutes in what took my school about 90 minutes
Wish this would be all😢
This series needs more views and likes; the content of the videos deserve WAY more views and likes.
Welcome to earth. Our people like to learn about the universe but not about how it works.
+Jairo San said what?
What's the difference?
william41017 Your statement makes 100% sense.
william41017 Cause they rely on old books to tell them about it but don't care for the actual physics thus low views....
+Null Null while that's true, people use outside help when they can't understand.
Thank you so much, I really needed this. We need more people like you and the guys from Crash Course, I thank all of them with the utmost love and appreciation. You are hero's that wear no capes.
Who is here, because they have physic test next day
You already know it 😂😂
I have a physics test next class
@@rosegalbloom7237 damn, i just came out of my test lol
Ye😢😅
@@swagzy4720 lol
I like how she never used the real rope...
It’s hard to be woke
It’s a little too short
I dont like that she did not use real rope
why ya'll complaining on this, did ya'll actually pay attention to the vid or to the rope?😂👌
LOL
whose here for digital learning
Meee
Lmao me ☝️
i think everyone)
Meee, the video my teacher gave us didn't have all the answers
Me
This is the best class i've never attended.
same here
you mean ever?
No i mean 'never'. Its a joke nevermnd hahah @Srushti patel
oh i get it
What grade are you in?
I love her videos, Ive used them this entire semester and its helped tremendously, totally have a B+ in Physics! Final is tomorrow thanks soo much!!!

To solve that maybe lower the speed
Real talk she kinda goes to fast for u to digest wat she says properly it's like she rushing to read off the teleprompter crash course philosophy phase is much more better but she is good also just goes a lil to fast
its called crash course for a reason -_-! crash course means a fast intense training of a subject.
This was way too compressed for me too. I’m going to try lowering the speed as well as pausing often. And before that, I’m going to do jumping jacks to get my heart going.
I kept scrolling and I couldn’t find the comment I was looking for. So I’m just gonna straight-up say it, she is very pretty.
Das Boi agreed hell yeah she is
No she definitely is not
Heard EXACTLY what I was looking for!! The speed of a wave depends ONLY on the medium!!! WOOOOOOOOOOOOOO!!!!!
My teacher KEEPS SAYING THAT
One of the most interesting series so far!
this must have been a pain to animate
2:00 I FELT LIKE THE SOUND WAS COMING AROUND/BEHIND ME AND FREAKED OUT FOR A SECOND XD
Lol
the sound waves coming from her voice makes me melt 😍😍😍
This is a great series. Kudos to the host.

i agree!!! they never tell us how to remember things and what they mean!!!!! they just keep shoving info down our throats!
Thats all that you need in the exam hall probably
That makes two of us.
I feel bad for you I guess they ain’t many good AP Physics teachers like mine
I have a fantastic physics teacher, I just i need to ask too many questions in too short a time before a test
THANK YOU for the *constant visual example* !!!
++ for making and sharing this crash course

THIS CHANNEL IS GOLD
The noise cancelling headphones thing is so cool!
I have a pair of noise cancelling headphones that I got for travelling on planes. It's fascinating but that signal it makes causes my head to feel SUPER WEIRD!

I have used a pair before myself, It was surreal

this video helped me to learn basic concept about waves
thank you mam
Who is here because they're not in school but curious about how the world works
3 years ago, I had no what this video was about and now I'm using this to catch up on my physics class lmao. How time has flown by
I wish I had this when I was teaching myself Physics C, this series is great.
this is a very complete video. tks it definitely helped me understand what my physics teacher was talking about
Yaaay! I've been waiting for sound to come up, it's my favourite topic in physics. I'm a musician and music teacher, so I need to be able to explain the science behind sound to my students from time to time ^_^
I love you I was so stressed about not knowing the content but you're so clear
I wish I had this video last semester!
At 1:38, I love the yellow "crest" on top of the yellow background lol.
wonderful job

+CrashCourse I think you made a mistake

So, really it's a short hand for us to say "Thanks!"
-Nick J.
Nice job! This video is so good!!!
YOU HAVE LITERALLY SAVED MY LIFE, THANK YOU SCIENCE WOMAN 👑👑
A good bit of this video I learned in the beginning chapters of my ultrasound physics class, I love this!!
I have a question. In the case of constructive superposition, each pulse has an energy of .5×kA^2. It means that the energy in the system is kA^2. But when they superpose, the amplitude becomes 2A. Then the energy in the system is
.5×k×(2A)^2=2×kA^2
Where does the extra energy comes from?
@Sebastian Barba dead meme sorry
This is the best channel for studies I've ever found.
Can you please complete this physics series before december, I am planning to complete my full portion before December. it'll help!
When this video was uploaded on TH-cam I was in my 8th standard and it is helping me now in 2022 in my college
Thank you so much Crash Course! It all makes a lot more sense now!
Crash course is a live saver!!
I just watch this for her awesome voice
Best episode yet!
THANK YOU CRASH COURSE!!! Helped so much with APs and classes :) Keep up the awesomeness!
Great video! :)
This is a huge help!I came here cuz we have a checkup test on waves❤Thank you very much!
Great video, summed just about all of my AS Physics module on waves last year super clearly!
Are we going to discuss the double slit experiment and quantum physics, or is this series focused only on mechanics?
This is one of my favorite topics in physics :-)
I love the amount of detail they go through
My mind is blown... this is so interesting
I LOVE YOU BECAUSE I ALWAYS FOUND NORMAL VIDEOS SO SLOW AND I LITERALLY GOT ANGRY WATCHING THEM BUT THIS IS PERFECT
One of the best Physics Tutor. #Kudos #Crashcourse
What a helpful series for an 8th grader!
this video surely makes physics way easier, special thanks to the crash course team
Fantastic video.
Where does the energy of the wave go at the instant of destructive interference? It can't disappear obviously, so how is it stored in that moment?
Oh my gosh! Thank you crash course! Now I understand this!
I fell in love.. With physics
helped so much thanks 😊👍
Absolutely funtastic explanations!! You're great!
Can I ask a simple question?
Why is it called traveling wave, is there any non-traveling ones?
That's a REALLY good question. The answer: Yes, there are! However, they are not called "non-traveling waves" they are called "standing waves"! Standing waves are fascinating. Since next week's topic is "Sound" there is a very good chance that standing waves will be covered, as standing waves come up a lot in the world of acoustics.
:D :D
simpelest way to look at standing waves is to look at the pictures of waves in this video like at 1:39. If the point where the rope moves through the barrier between orange and blue doesn't move to the left or the right it is a standing wave.

Thanks guys
wow this was really useful , thank you
CrashCourse is the BEST thing that has ever happened to Me.
This singular video was more helpful than an entire semester of lectures
fav channel for studying
she doesn't repeat herself, focused, I hope other guys in @CrashCourse do the same. I always put astronomy videos' playback speed at 1.75
Informative video. Thanks
I have to say, this really explains what my teacher told me in 3 hours, in less than 10 minutes
So helpful
Lol 3 hours binge watching this might worth more than 3 years of my physics class
thank you sister!
damn that rope is magic
Gerald Ellis woke af
Thanks from all of my heart to someone who put arabic sub 😍
i love this channel
best teacher alive. 🔥
Excellent!
Fantastic!
Lovely video
Amazing!
Thank you for all your help! I can now survive statics and physics. :)
thank you
Who’s here for Virtual school (online school bc Coronavirus ) Stay safe Crash Course and people in the world!
Such an interesting topic ✨✨
This video help me a lot
You are sooo good....i had become an addict to physics bcze of YOU😍
superb
loved it...
This is great! :D
love these videos. it's a funnier way of learning.
This is a huge improvement in the speaker's voice. She's speaking more slowly and anunciating. The auto-generated captions only had six mistakes.
If only I had this show while I was studying Physics in Highschool.
At time 1:17, they show 1.5 wavelengths to equal the diameter. What do you think? Is this correct? Should the wavelength be equal to 2 diameters (1 diameter is half of a wavelength)? I know that this isn't related to the rest of the video, but it made me wonder.
this reminded me of my high school physics class. I miss my teacher so much! (said a recent college graduate )
Thank you!!

Anyone else find this somewhat confusing but interesting? :D
yip
+DatHam
a little confusing
It should be confusing. If it didn't confuse you at all you probably wouldn't understand it ;p
You should mention what part (s) were confusing so others may try increase the amplitude of your understanding with a little constructive interference. ;)
One graphic replaced her word, "stretching," with "rarefaction." That can throw you off even if you know what it means.
Odlican video jako mi se svidja😍😍
