What would you say to a parent of a student with an A in an AP class at parent-teacher conferences who asks how they can support their child at home?

Nice, I love the train tracks argument!

Michael Freeman @afreeparticle.com · 1d

It might be my imagination or other factors, but I think this got somewhat better when I made my first example an angled projectile instead of a horizontally launched one, and save horizontally launched as a special case.

Hey #iteachphysics ! I working with some science/physics teachers later this week about using @desmos.com in class, most who are new to Desmos. Is there a feature you use a lot? Something you wished you learned sooner? Favorite graph? TIA!

In 2001, Sadler and Tai’s paper “Success in Introductory College Physics: The Role of High School Preparation” noted that a variable that seemed to correlate to higher grades in college physics was “using no textbook at all or reading it less.” #ITeachPhysics

Yep, and if accelerating, depending on the situation, a friction force might point left or right.

Not sure I understand the forces in the list here though. When I draw a system schema I might break the contact force between B and A into 2 components (normal and parallel/friction), but this seems to have 3 components?

Alrght everybody, get your Tin Can Telephones out. We need your help!

We reach new people by word of mouth. Send all your educator friends this pic! Teachers, librarians, scout troop leaders, etc! We offer our program for free, so we need help getting the word out without advertising $$.

A purple and red octopus talk to each other on the tin can telephone. Purple octopus says “want to connect your students with real
Scientists?” Then red octopus says “Skype a scientist matches groups with scientists for virtual q&as. It’s free!” And then an orange flapjack octopus says “get a match at skypeascientist.com”

"Consumers must spend $800 billion on AI within a few years, to justify investment from 2023-24"

lol. LOL. LMAO. LMFAO. OMGWTFBBQ.

Christopher Mims @mims.bsky.social · 12d

*The AI boom = one of the costliest building sprees in world history

* Past 3 years' commitments are greater than the cost of building the U.S. interstate highway system

* Consumers must spend $800 billion on AI within a few years, to justify investment from 2023-24

www.wsj.com/tech/ai/ai-b...

This week, consultants at Bain & Co. estimated the wave of AI infrastructure spending will require $2 trillion in annual AI revenue by 2030. By comparison, that is more than the combined 2024 revenue of Amazon, Apple, Alphabet, Microsoft, Meta and Nvidia, and more than five times the size of the entire global subscription software market.

Morgan Stanley estimates that last year there was around $45 billion of revenue for AI products. The sector makes money from a combination of subscription fees for chatbots such as ChatGPT and money paid to use these companies’ data centers.

How the tech sector will cover the gap is “the trillion dollar question,” said Mark Moerdler, an analyst at Bernstein.
