I'm going to start the day with a feel good news story.
Two New Orleans
high school girls solved a 2,000 year-old "impossible" mathematical problem.
Here's what they did cut from the news story. Trigonometry is based on Pythagoras' Theorem (A^2 + B^2 = C^2), but using trigonometry to prove Pythagoras's Theorem is what's known as circular logic.
They found a way to prove the theory using trigonometry WITHOUT circular logic.
Here's a link to the full story, that also has a video of them proving the theory:
