Let’s learn about parabolas! With so many different manifestations of parabolas out there, it seems like every one should have a vastly different equation… but no! The basic parabolas are versions of the same thing— a quadratic equation. https://www.youtube.com/watch?v=oM7yd...

Today’s episode of European history features the dissident punks of East Germany, labor strikes in Poland, and the fall of the Berlin Wall.

An Update from the Crash Course Team: It’s our mission at Crash Course to make our videos accessible and enjoyable for everyone: lifelong learners, teachers, and students of all ages. To ensure our videos and comments sections are respectful and productive spaces for all our viewers, we are making some changes to how comments work on Crash Course videos. Starting this week, all comments on new Crash Course videos will be moderated and held for review. This means that when you leave a comment, it will have to be approved before it is published. Our team will approve comments for typically 48 hours after the video is published. After that, new comments will not be posted but we encourage you to continue to engage with videos on social media, in the community tab, or on Patreon. On past videos, the comments sections are now closed to new comments. There may be a few instances where we allow comments to be published without review, such as in lab videos where we’ve seen that collaboration in comments has been important to viewers’ understanding. There may also be some videos where we choose to turn off comments completely if there is an overwhelming amount of hateful or baseless comments. What kinds of comments are we looking for? We appreciate comments that are clear, thoughtful, and relevant to the video. Your constructive criticism, advice, and unique insights are important to us and will be approved. What kinds of comments will not be approved? Any comments that are inappropriate, hateful, incoherent, or baseless will not be published. We also do not permit personal attacks, profanity, or commercial promotions. Thank you for your understanding as we work to make sure our community is welcoming and beneficial to all learners! EDIT: We understand your concerns about the 48 hours window, and we hope the community tab can be a place for more active discussion going forward. Unfortunately, with a moderated comment section, we have to shut off comments after 48 hours because of the amount of time it takes our team to go through comments and approve them. It would simply not be realistic to continually moderate comments on 1000+ videos.

As modern day communicators, we have to understand how to communicate on many different platforms, from formal emails to comments on a google doc to tweets!
