This is one of my favorite shots: www.instagram.com/p/DZYcyeazMHk/ Absolutely magical flying loaf. Is Robin a spaceship?

Sometimes when working on a #desmos I have a sudden crazy idea and try it out and it just works like magic. #ITeachPhysics

I so love the sensibility of #Puzzmo crossword clues. (This is from their current ‘big crossword’ by @pocketsquar.es ) #atla

Before the Boston Marathon this year, those animals were wearing race bibs! I took this when I saw them. The statue is “Arms of Friendship”.

In my geometric #optics sim in #Desmos, I've added an easy toggle between the principal image-forming rays and a set of parallel incident rays to allow easy illustration of what the focal point "is". #ITeachPhysics Also I made them be pretty rainbow colors. Happy Pride month!

Mind reeling

It was a very cool spring so far but the spring peepers (frogs) are finally making themselves known. (Sound on!) #frog #wildlife

I always start the #Wordle with the previous day’s solution. My partner sometimes does as well, and it’s fun to see how we diverge from there. These were from a few days back, prompting an instance of our “we’re so in sync” joke. The saint/stain 2nd guess was funny enough but allay also?

Continuing to update/upgrade my old electrostatic field simulation in Desmos and realized my new design allowed for arbitrary external potentials and line charges... #desmos #ITeachPhysics

If you talk about stuff the notice doesn't ask about, it may not be counted/tabulated. It uses phrase "we seek comment" a few times but this is the most relevant section. They are proposing to ask for more "family-oriented" and faith-based organizations to be on the TVOMB. They are also asking ...

To my reading, "gender identity issues" are the only specific thing it mentions in its otherwise broad questions about the accuracy and effectiveness of the existing voluntary TV ratings system and the industry panel (TVOMB) which runs it. Try to *directly address the notice* in your comments.

In the article's last section it quotes another scientist (not from the team) as shown here. None of the people who study this seem to think gravity itself is the reason for the differences. Instead they think there are things going on with their own equipment that they haven't fully figured out.

A fun detail: to help eliminate bias on the part of the researchers, they had a colleague alter some of the masses in their torsion balance and keep the details in a secret envelope. Schlamminger opened it on-stage while presenting their results at a conference.

It includes this wonderful graphic showing the values and error bars on various attempts going back to 1982. The article focuses on the most recent effort--led by Stephan Schlamminger--to replicate a previous one and how, ultimately, they got a different value. [sad trombone sound]

Here's my lecture notes' physical pendulum, made by joining several ellipses together into one object. It occurs to me the density must be highly nonuniform to get the center of mass so far down there, but I guess that's fine since it's arbitrary anyway. :)

Here is what I put into the "help docs improve" feedback tool. Simply placing the cursor on a word (or being in the middle of moving through it) should not trigger a distracting box that obscures your document and interrupts visual continuity. Especially such a STUPID box.

Google Docs now shows an enormous tooltip any time you put your cursor in a word that was flagged by the spellchecker. There are many interactable elements in this box but none of them are "I know how spellcheck works, please don't show this again." I love sending Google feedback though, so...

Fascinating queries being made on @merriam-webster.com today. (I watched it hover at #2 for a while, break #1, and then gradually slip off the list.)

Enjoying #Pokopia quite a bit so far. Scyther is super pumped about the wildflowers I put in by its habitat. #pokemon

I prefer to say that a vector is a quantity that, to specify it fully, needs a number of values equal to the number of dimensions you're working in. There are many different styles you can do it in, but you'll need (at least) that many values. In fact... ha, found this graphic I made awhile back:

In my graph you can also turn on shading to show the energetically-permitted final states. (Assuming no hidden energy is released and you aren't lowering the KE below a stick-together value.) My students often use a constant-KE method even without knowing if the collision is elastic. #ITeachPhysics

I put together an inverse square law #desmos sim. It includes two intensity probe points for seeing ratios, as well as adjustable collectors/receivers for looking at area and power. Happy to hear feedback from #ITeachPhysics folks! www.desmos.com/calculator/8...

This example is absurdly contrived. This is not something that requires a specialized program and definitely doesn't call for anodyne, mass-produced text (with errors) to be spewed at reps. You need simple "please support/don't" calls and authentic human pleas, not robots.

This graph now has "ground" lines drawn in that scroll by according to your reference frame velocity, helping to visually communicate the motion of the wheel. I improved the interface a little bit as well. Same link as in original post: www.desmos.com/calculator/f...

Been tinkering with this little #desmos thing, a way of showing velocities of points on a rolling wheel with a selectable reference frame velocity to see how that changes things. (This could also pass for rolling with some slipping.) #ITeachPhysics www.desmos.com/calculator/f...

One of my favorite adventure tropes—especially finding them in video games—is “boat in a cave”. I’ve been playing and enjoying Star Wars Outlaws and… this wrecked sandcrawler sort of counts I think? #BoatInACave #VirtualPhotography #StarWars

During the quiz I saw a pretty good number of kids laughing and/or rolling their eyes at my "how do you do fellow kids" problem-theming, but sadly nobody wrote any sardonic comments about it on their papers.
