Waves are cool. The more we learn about waves, the more we learn about a lot of things in physics. Everything from earthquakes to music! Ropes can tell us a lot about how traveling waves work so, in this episode of Crash Course Physics, Shini uses ropes to talk about how waves carry energy and how different kinds of waves transmit energy differently.

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.

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.

@hibiscusman
@hibiscusman 8 лет назад
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.
