1. An 80-year-old in Canada now holds a world record for donating more blood than any other woman. She started in 1965 when she was 22, and she’s now donated over 200 units. That’s around 30 gallons of blood in her life. Her blood type is O-positive, which is the most common kind. So it’s in high demand.
2. Two teenage girls in New Orleans just solved a math problem that’s been stumping mathematicians for 2,000 years. It has to do with the Pythagorean Theorem for sides on a triangle . . . A-squared, plus B-squared, equals C-squared.
That formula is taught in every geometry class, but it’s not ideal because of something called “circular reasoning.” So they managed to prove it using trigonometry instead, and that’s a big deal. They just gave a presentation at a math conference this month and were the only high schoolers in the room.
Calcea Johnson and Ne’Kiya Jackson, students of St Mary’s Academy, say they have proven Pythagoras’s theorem by using trigonometry. Johnson and Jackson recently presented their findings at our south-eastern semi-annual sectional meeting in Georgia!https://t.co/KUHlbbUWaN

3. Greylon Anthony was 1 of the top 5 drivers with the most thank yous—a program over the holidays to recognize great drivers and tip $5 on behalf of the company. Anthony selected Atrium Health Levine Children’s Hospital, which received a $10,000 donation. He said he selected the hospital so they can purchase essentials and provide care for pediatric patients
