PERIODICALLY: We at MPA haven't spent enough time with the periodic table of elements, so whenever I see an interesting graphic featuring it, I try to pay attention. One that caught my eye this morning was a table that illustrates how we interact with each element.
It was created by Boeing software engineer Keith Enevoldsen. He has kindly made it available online to view or download it for free.
The table is color-coded to show the chemical groupings. Small symbols pack in additional information: solid/liquid/gas, color of element, common in the human body, common in the earth's crust, magnetic metals, noble metals, radioactive, and rare or never found in nature.
There's also a companion graphic that is done in words.
I printed out both today. Hopefully we'll all spend plenty of time gazing at them.
ENGINEERING: We're on the email list for Seattle's future National Hockey League team, and today's update included an interesting 60-second video about how the "new" arena is being constructed. It's really a massive remodel of old Key Arena (built back in the early 1960s, for the 1962 Seattle World's Fair.
The video is mostly about engineering - how to make the structure seismically safe, and how the roof is held up with a 'kickstand' of sorts.

FLY BY: It's been way too long since we watch an International Space Station fly over, so we righted that wrong this evening. About the only good thing about it getting dark at 4:30 p.m. is that you have more opportunities to see the ISS overhead.
Any time you want to know who's on board and what they're doing, you can visit NASA's ISS website.
Here are the astronauts on board right now.
Try memorizing the PT for a good mental exercise. Doing it by columns also teaches how chemical properties relate to elements' electron /protons numbers
