plotting the four energy terms of a double pendulum as a stacked bar chart.
the total height of the bar is constant (conservation of energy), though each individual part behaves chaotically
To use the Montreal subway, you tap a paper ticket against the turnstile and it opens. But how does it work? And how can the ticket be so cheap that it's disposable? I opened up the tiny NFC chip inside to find out more... 1/15
Jason came in as champion overall, while Jenny claimed second. Great showing from our friends Sahasrad from LT (3rd overall, 2nd in physics) and Kruthi from Reedy (1st in bio), as well! @friscoisd students are superstars!
Our LHS Science team cleaned up at state! 1st place team (Jason Xie, Adler Xu, Christine Rittenhouse (Coach), Bryan Zheng , Jenny Wang). Individual placings of 2nd place biology (Jason Xie), 1st place Chemistry (Jenny Wang). #RedhawkPride
More #LK99 good/bad news. Good news is more results have been reported. Bad news is exactly the same. NTU, an excellent university which has sent its students as PhD students and postdocs to CMTC over the years, reports insulating resistivity increasing with decreasing T and...
If my average speed going from A to B is 60 mph and my average speed going from B to A is 30 mph, what was my overall average speed?
Believe it or not, the answer is NOT 45 mph.
i think one of the most formative moments in my physics education was when my nobel-prize-winning physics prof in freshman year of undergrad wrote an integral on the board, stared at it for a bit, and then went “hmm. i haven’t actually done an integral for.., several years.”
Probably the best thing you'll see today.
In 2017, a group of developers hilariously competed for who could create worst volume control interface in the world.

This may be one of the largest ecological disasters in US history.
There were roughly 100,000 gallons or 1,000,000 pounds of Vinyl Chloride leaked, spilled and burned at #EastPalestine crash.
Acid rain and Phosgene will decimate the zones ecology.
