It’s important to try and gain new knowledge each day.   Here’s what I learned:

• Phosphorous was discovered when a 1600’s scientist/alchemist was trying to make a ‘philosopher’s stone’ out of his own pee.
• The legal status of Western-Sahara Africa.  And it’s relations with Morocco.  That’s why political maps of the area always have it grayed out.
• London used to be called Londinium, back when it was founded by the Romans.
• Ball Lightning is likely a result of what essentially amounts to silicon dust.
