Things I learned lately 21 Feb

• Women Air-force Service Pilots (WASP) (substitute Army and Auxiliary as well) were trained women pilots, whose job it was to test, ferry aircraft from factory to airbase and train other pilots. WASP freed up male pilots for combat during World War II. Despite the armed forces being involved in the creation of WASP, its members had no military standing. They numbered 1,074 women pilots.
• In North Carolina, a white police officer pulled a black man and his daughter over and when the office noticed the girl didn't have a car seat, the man explained he couldn't afford one. The office had the man follow him to Walmart where he bought a car seat with his own money.
• Insomnia Cookies delivers warm cookies to your door until 3 am (US only). It was started by a university student 17 years ago and was acquired by Krispy Kreme in 2018.
• Minnesota has set aside funding to encourage homeowners to plant bee-friendly plants, such as Dutch white clover and creeping thyme.
• Some Girl Scouts have been setting up their cookie selling tables just outside marijuana dispensaries. Brilliant.
• The Guangzhou metro area in China has 56 million residents, more than all of Canada.
• The experts understand how lift is generated by a wing, but nobody agrees on why lift is generated by a wing. Bernoulli's Theorem and Newton's Third Law complement each other on the how, but neither explain the why.
• Canning jars are also known as Mason jars and Kilner jars to honour their inventors.
