Adafruit: Learning Electronics The Fun Way

​Adafruit, the brainchild of Limor Fried for teaching electronics, has debuted a wonderful cartoon called Circuit Playground. Being an electrical engineer, I love seeing simplified attempts to describe the complexity behind the things that everyone uses - everyone plugs in a lamp!

The video below describes what current actually as - a flow of electrons. Most electronic devices have a suggested rating for amps (normally listed as A)​ in honor of scientist André-Marie Ampère. Amps is a measure of the amount of electrons that flows per second. Too little amps and the electronic device won't function.  Too many and it'll fry!

Women In Chemistry Documentary = Awesome

I had the pleasure of attending a screening of the Women in Chemistry documentary (trailer shown above) by local NPR affiliate WHYY in Philadelphia. This amazing documentary profiles eight women that have changed the course of chemistry and science in general.  Afterwards, we were treated to a Q&A moderated by Maiken Scott  with two of the women profiled in the video - Uma Chowdry and Mary Good. I asked a question a;bout getting kids engaged that don't have a support system that pushes science.  Both Mary and Uma told me to start with the problems that students are facing, and design solutions while focusing on the math and science aspects.  This is a winning idea!

The full list of profiled women is below:

• Nancy Chang, cofounder and former CEO of the biopharmaceutical firm Tanox;
• Uma Chowdhry, retired senior vice president and chief science and technology officer of DuPont;
• Mildred Cohn, first female president of the American Society for Biochemistry and Molecular Biology;
• Mary L. Good, former president of the American Chemical Society, undersecretary for technology in the U.S. Department of Commerce under President Bill Clinton, and recipient of the Priestley Medal;
• Kathryn Hach-Darrow, cofounder of the Hach Chemical Company and the only woman to receive CHF’s Pittcon Heritage Award;
• Paula Hammond, David H. Koch Professor in engineering at the Massachusetts Institute of Technology;
• Stephanie Kwolek, former research associate at DuPont and inventor of Kevlar; and
• Kiran Mazumdar-Shaw, founder, chairman, and managing director of Biocon Limited.

STEMnasium: A Great Way to Teach Kids Science

Jon Skief founded the Harambee Charter School in West Philly in 1973. The school has been providing a quality science based education for children for 40 years, and recently received national attention 6 year old Zora Ball. She became one of the youngest people to develop a mobile gaming app.

Tairq Al-Nasir, head of the STEMnasium Learning Academy, adds the following stats:​

In 2011, Philadelphia regional companies had 64,000 STEM-related and finance job openings, but area colleges graduated just 6,000 people with those degrees, according to Campus Philly. Al-Nasier widens the numbers even more.

“Every year, there’s a demand for 120,000 jobs for people with computer science backgrounds,” Al-Nasir said. “We’re only graduating nationally, 40,000. There are 80,000 students missing. Why is it missing? It’s missing because we haven’t rethought the STEM initiative.”

International Women's Day: Math is For All

Today is International Women's Day, and we should all celebrate the wonderful women that have made impacts in our lives. Google has an amazing doodle on its homepage to serve as a great launching point.  But y'all know that I'm all about the math and science, and making sure that everyone gets into it. 

Well, everyone except "math is tough" Barbie:​

​I ran into that video while reading about the stereotype of gender issues between men and women. I've often heard that men are better at math, and it becomes a bit of a self fufilling prophecy when I hear some of the women that I tutor repeat this myth. What boggles the mind is that some of these women repeat it even when they are damned good at math.

An interesting piece of data that comes out of the story is that we focus so much on tests, even though tests don't necessarily reflect classroom performance. We all know that women are beginning to dominate college, and I remember my advanced math and science classes in high school containing men and women. Despite that, repeatedly hearing "women can't do math or science" does have an effect, and at times can be a self fulfilling prophecy. I've tutored women that are stellar in math, yet still believe that they are not.   

Also, there's this:

Math aptitude (even measured at the levels of outstanding instead of average performance) doesn’t explain sex disparities in science careers (most of which, incidentally, only require you to be pretty good at math, as opposed to wildly genius at it). In any case, scoring high in math is only loosely related to who opts for a scientific career, especially for girls. Many high scoring girls don’t go into science, and many poor scoring boys do.​

This is key - you only need to be proficient at math and problem solving to be successful in a technical career. You don't need to be AMAZING at it unless you want to be a theorist or go for the PhD.​

Let's celebrate International Women's Day by making sure that math and science reflect the diversity of the world!​

The Intersection of Science, Race & Media

A few of us got together in a Google+ hangout to talk about the intersection between science, race & media. We filmed the video below as a response to a Loop21 Twitter chat on race & media in which there was very little discussion about science.  

The group features Dr. Caleph B. Wilson, Dr. Danielle N. Lee, journalist Jamila Bey, and myself. Unofficially known as the Dark Sci, we plan on pushing the conversation forward regarding the communication of science to a broader audience.
