Welcome to the July “Today I Learned” thread, an opportunity for anyone to share something they found fascinating about a topic of interest. Cake is about having “Better Conversations,” and the more you know about a topic the more you can enjoy new conversations as a reader or participant.
A few posting guidelines for everyone’s benefit:
In your post,
• Add the topic covered at the top of your post.
• Provide an explanation for why you found it fascinating.
• If sharing quotes, please provide a link to your source.
• Please refrain from sharing YouTube videos to this thread: posts to this thread containing links to videos will be hidden from all. (If you want to share a #TIL that requires a YouTube video, you should create a separate conversation to do so.)
