@RobertTalbert I'm planning to lean into presentation/discussion of data in next semester's num methods (engineering) course... AI seems mediocre in that realm for now. Also considering specs grading but worried that would be too many experiments at once. A few weeks to figure it out though!

@srothschild1 @spencerideas I agree, very strong correlation between RBI and OPS. I think this metaphor is extremely strained: there is room on a baseball team for a player with poor RBI/OPS but good defense. If a team is built of 8 first basemen with good RBI, they stink. Diverse skills are measured.

@NedLuberecki @SteveMartinToGo Did @SteveMartinToGo really have this one written in the early 80's and held onto it until his 2009 album?

Known by bluegrass banjo players since the 1940s! Often the band plays a swing feel while the banjo plays straight, puts every 2nd banjo note ahead of the beat. It makes it feel like the banjo is pushing ahead -- exciting! See Earl Scruggs in https://t.co/YMoEFQEkRC at 0:45

@joshua_r_eyler Just signed up, gonna catch as much as I can. Thanks Josh!

[Jeremy Koch @_JeremyKoch]

@joshua_r_eyler Will a recording be posted later? I think I am experiencing too much start-of-semester chaos to make it...

@DrDeCaluwe Wait, can the extremely digital "Fitter, happier" even be rendered in analog?

@mjahore I have heard they taste more like the Runts candy banana flavor. Awaiting your report.

@siwelwerd @RobertTalbert This is beautiful Drew thanks for giving me confidence to try it!

@garethmckinley Do you do any course projects in grad fluids? (Star Wars related or otherwise...)

@RobertTalbert This keeps students cognizant of deadline but provides a streamlined process to give pressure relief if necessary. I have observed certain groups are more willing to ask for extensions via email -- this would help others who are more tentative about asking. Any thoughts? (2/2)

[Jeremy Koch @_JeremyKoch]

@RobertTalbert I am thinking about trying this in a STEM course this fall: a google form that, if the student fills it out before the deadline (w/ just name, assignment number, no personal details needed), automatically grants the student a 24-hour extension. (1/2)

@dpholmes Residual stresses. You can buy strings that are cryo-treated which eliminates the residual stresses.

I also think it takes a bit for the string to seat itself around the tuning peg, nut, saddle, and bridge pins.

@stevenstrogatz It seems reasonable, though by no means trivial, that this, coupled with the continuity constraint, might lead to an explanation of lift when viewed through the prism of variations.

[Jeremy Koch @_JeremyKoch]

@stevenstrogatz The "other part" of the Bernoulli derivation (normal to streamlines) looks like: ρu^2 / R = dp/dn, where R is the local radius of curvature. (When streamlines curve, there is a pressure difference "inside" vs "outside".)

@zhigangsuo Work can raise something to a height, but thermal energy isn't going to lift anything on its own.

Sure thermal energy can ultimately be used to lift something by now we've got a heat engine involved and the definition is getting obfuscated.

@DrDeCaluwe Next time this realistic situation happens convince them to play Miserlou -- it's the same whether the guitar is strung left- or right-handed.

@TimWhite_51 Now if you could just get ahold of the ventilation diagrams for each classroom...

@KDalnokiVeress @dpholmes Read some of David Politzer's stuff about banjo physics if you want to see how little we understand: https://t.co/Y15jS5jPUK
