Seems like our theme this week @ULSF is movies and math. That is, Alex @Csete has been “learning gstreamer with the purpose of encoding one or more video streams and muxing them together into a single MPEG-TS transport stream”. Alex is collecting useful shortcuts into http://wiki.oz9aec.net/index.php/Gstreamer_Cheatsheet
On the math front, I found a great little book “Understanding Thermodynamics” by H.C. Van Ness. Van Ness develops an experiential introduction to the subject and contrasts it momentarily to the usual abstract approach. Made me think. Subjects in the abstract can be a real headache, and it’s always important to feed the brain with the practical elements either through more practical studies or direct experimentation or modeling. It’s too easy to plow through math like a school boy and miss the greatest value the time spent in study has to offer. Making good cognitive structures feeds the brain what it needs when it needs it. So following good tangents is building better networks.
I think that such an idea is more useful than nothing, like eat your broccoli.
Warning. Might not be good for your GPA, however. That’s not a concern of mine, so accommodating that kind of objective is left as an exercise…. Maybe, do your homework first and then manage a stack of books next to your bed in all the tangential areas of interest.
If you’re reading this, then you might enjoy H.C. Van Ness’ little book. Even if you know the subject, it’s fun. I’d be interested in hearing other opinions.
On another front, yet another interesting tweet by @AronSora linked to Protecting the Lunar Farside. In a nutshell, Protecting the Lunar Farside in the electromagnetic spectrum in favor of
future radio telescope or phased array detectors. Leave E-M L2 Alone! The
Protected Antipode Circle (PAC) is defined as a circular piece of the
Lunar Surface 1820
kilometers in diameter, centered around the antipode on the farside and
spanning an angle of 30 degrees in longitude and latitude from the antipode.
Always interested in learning and sharing Lunar conservation and management concepts.
