February, as everyone knows, is Black History Month. And while many people are familiar with the contributions of African-American writers, artists, musicians and athletes, many may not be so familiar with the many contributions African-Americans have made in the many fields of science, from mathematics to medicine to astrophycsics and beyond.
Biography.com has a great list of Black people who made groundbreaking first contributions to their fields. And one of the first in US history was astrophysicist, city planner and scientist Benjamin Banneker.
The Solar One Education team is excited to launch our new, enhanced website, thegreendesignlab.org!
The new website is easy to navigate and offers new features for registering for our Professional Development Workshops, the Green Design Lab Energy Challenge, and a host of resources for our Sustainable Schools Network members!
Since its inception 6 years ago, the Green Design Lab has grown to reach teachers and students in over 400 schools. During this time, Solar One Educators have provided professional development training for teachers on our hands-on curriculum, in-class programming for students, and support for energy reduction and school sustainability projects. With the development and growth of the Green Design Lab Sustainable Schools Network (SSN), Solar One Educators have reached teachers across the United States.
One of the simplest “green” lifestyle changes is to give up buying bottled water. Americans used 50 million single-use water bottles last year, and we have dismal national recycling rate of only 23%. Cutting them out of your life and budget makes good economic and environmental sense, and many bottled waters are actually tap water in a fancy package and nothing more. So is there really a difference between bottled and tap water- a difference you can actually taste?
Pi may be the most commonly used, well-known and popular irrational number and mathematical constant, famous for its usefulness in geometry and its infinite series of decimal numbers. In the ancient world, an exact computation of pi went to between 5 and 7 digits, but with the help of supercomputers, pi has currently been computed to over 13 trillion digits.
Every year March 14 is celebrated as Pi Day, as the first 3 digits are 3.14. But this year’s Pi Day is very special, because this Saturday, Pi Day will represent the first four digits, 3.1415! And at 9:26:53 precisely on Saturday morning, we will experience the calendar equivalent of 10 digits of pi! This special Extra-Pi Day happens only once a century, so chew on that while you’re chewing on some kind of delicious pie. On Ultimate Pi Day.
Happy 270th birthday to Italian physicist Alessandro Giuseppe Antonio Anastasio Volta, Italian physicist and inventor of the first chemical-electric battery, known as “the Voltaic pile”. And now you also know where the word “voltaic”, as in “photovoltaic” which means “electricity from light”.
Napoleon Bonaparte was a fan, and Volta was invited by the Emperor to demonstrate the battery at the Institute of France.
