One of the most accomplished engineers I have had the privilege of interviewing was Mary L. Spaeth, a specialist in the field of laser optics.
Spaeth was a pioneer who discovered the world’s first “tunable” laser.
While researching ruby lasers at Hughes Aircraft Corp., Spaeth “came to believe that dyes would make excellent lasers.” Dyes are strongly colored chemicals that can be used to add color to a material, such as hair or cloth.
The year was 1966, only six years after the first laser was invented. Continue reading
As someone with a degree in engineering, I’ve noticed a peculiar fact. In the world of STEM (Science-Technology-Engineering-Math) engineering careers appear to be the ugly ducklings of the group.
There’s a lot of talk about teaching kids to code, which falls under math, computer science and technology. There’s also a huge emphasis in the media on biotech, space science, and environmental science.
But in my opinion, the lowly engineer gets short shrift. Continue reading
Cities large and small are buying in to the Smart Cities movement, addressing the challenges of increasing urbanization using data and technology. Women in particular are prominently positioned as leaders in the movement, seeking to create more livable, efficient and sustainable cities through their technical, business and civic know-how.
As more and more people flood into cities worldwide, local governments are being called upon to help provide more services such as healthcare, economic development, infrastructure and safety to their burgeoning populations.
At the same time, the state of technology multiplies exponentially the amount of data being collected—as well as the possibilities of what can be done with this data. Continue reading
Alessandra Luchini, a Ph.D. and assistant professor at George Mason University, has helped to invent a “nanoparticle trap” which allows scientists to detect unhealthy cells much sooner than before. When found early, cancer and other diseases are easier to treat, giving patients a better chance for survival.
Recently, Luchini gave a lecture on “Nanotechnology in Biomedicine” as part of Mason’s Vision Series at the Hylton Performing Arts Center in Manassas, Virginia. Continue reading
