CodeGuppy Smiley Project

Many programmers got hooked on coding when they found a simple way to write code, saw the result of their code, then changed their code, saw their change, and played around with code. The CodeGuppy website makes this discovery process both easy and fun to experience. This project is fairly simple to create AND, equally important, easy to tweak and play with to see what happens.

Ancient Technologies

Chasing a link about people making ice in the deserts of Iran a couple millennia ago led to an equally interesting video about ancient technologies. Whether ancient or modern, technologies are design to solve problems. And many of the problems we have are the same today as yesterday and tomorrow.

Mother Nature Doesn't Need Google

Did you ever think about how Mother Nature never has to Google anything? Plants and animals all around the globe know instinctively what to do, and how to survive and thrive in the surroundings they find themselves in. Luckily, lots of people have noticed this.

Many things we use every day have been inspired by observing nature, and how it all works. Everything from butterfly wings to bird nests to termites can teach us something that will help us solve our human problems if we look hard enough. This is called biomimicry. That means investigating how nature has evolved to solve problems, and then implementing what was learned.




Why is the Sky Blue?

From NASA: "Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered more than the other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time."



Frank Mann

“Frank Calvin Mann was a mechanical genius. He was an aeronautical and aerospace engineer, award-winning sports car designer, solder of fortune in the Second Italo-Ethiopian War, primary civilian instructor of the famous Tuskegee Airmen, and a World War II officer in the Army Air Corps. Another interesting fact about Frank— he was a lifelong friend and associate of, and behind-the-scenes troubleshooter and engineer for, the world-famous film producer, industrialist, philanthropist, and aviator, Howard Hughes— who at the time was one of the richest men in the world.

Frank Mann owed his education and career to Howard Hughes, and he repaid his friend and mentor Howard by remaining loyal to him into his twilight years.”

This Week

Our Sunday issue this week will have fun often offbeat links about concrete that melts snow, microbes and your brain health, friendships between animals, what night sky looks like on Mars, and more.

Why was the math book sad? Because it had too many problems. :-)
