You learn something new every day; what did you learn today?

Submit interesting and specific facts that you just found out (not broad information you looked up, TodayILearned is not /r/wikipedia).

Posting rules

1. Submissions must be verifiable. Please link directly to a reliable source that supports the claim in your post title. Images alone do not count as valid references. Videos are fine so long as they come from reputable sources (e.g. BBC, discovery, etc).

2. No personal opinions, anecdotes or subjective statements (e.g "TIL xyz is a great movie").

3. No news or recent sources. News and any sources (blog, article, press release, video, etc.) more recent than two months are not allowed.

4. No politics. Historical politics are fine, but anything relating to current politics/politicians is not allowed.

5. No misleading claims. Posts that omit essential information, or present unrelated facts in a way that suggest a connection, will be removed.

6. Rephrase your post title if the following are not met:

   1. Titles must begin with "TIL ..."
   2. Make them descriptive, concise and specific (e.g. not "TIL something interesting about bacon").
   3. Titles must be able to stand on their own without requiring readers to click on a link. Starting your title with a why/what/who/where/how modifier should be unnecessary.
   4. "TIL about ..." and other broad posts don't belong on TIL. Try /r/Wikipedia, etc. instead, or be more specific (and avoid the word "about").
   5. "TIL how to ..." posts belong on /r/HowTo.

7. No trivial or obvious facts (e.g. "TIL the sky is blue"), or facts that appeal only to a narrow audience, specifically no software/website tips (e.g. "TIL you can click on widgets in WidgetMaker 1.22").
