Can Humans Affect our local Space Weather?

Very interesting article on the NASA blog about how human activity can affect Space Weather around our planet. From the article:

“A number of experiments and observations have figured out that, under the right conditions, radio communications signals in the VLF frequency range can in fact affect the properties of the high-energy radiation environment around the Earth,” said Phil Erickson, assistant director at the MIT Haystack Observatory, Westford, Massachusetts.

Another NASA video (screenshot below) explains how “Human Activity Impacted Space Weather“, based on results of experiments from Cold War nuclear tests.

Why Does Coding Matter?

In December 2014, I wrote a special edition article for the “Teaching & Learning” blog at Head-Royce. It was a reflection on why Coding & CS are so important for the next generation. I think it is still very relevant one year later. Check it out by clicking below:

2nd Annual Hour of Code at Head-Royce!

For the 2nd year in a row, I led the efforts to coordinate an  Hour of Code as well as other various STEAM activities (3d printing, LED ornaments for our Digital Citizenship Community Tree), for students in K-12. Click the image below to learn more!
