If you've reached this blog post from the YouTube video, I apologize - there is no publication on a new mathematical development in topological manifold theory. For being a good sport, please use code: april1 for 20% off a sticker combo pack in our shop.

If you haven't seen the video yet, I've got some news for you! There's a new mathematical development in topological manifold theory that allows us, for the first time, to change inner tubes and bike chains without removing the wheel.

Check it out!
