Sometimes you need to forego the intuitive way to define stuff for the sake of actually being able to do anything useful with those definitions.

#knots 🧪 🎢

Two white curves on a black background. The first is a circular loop, labelled as "A knot". The second is a overhand knot, labelled as "Not a knot".

Guralnik, Hagen, and Kibble submitted their paper "Global Conservation Laws and Massless Particles" to Physical Review Letters #OTD in 1964. It was one of three important papers, by three groups of authors, developing what we now call the Higgs Mechanism.

The title page reads:

GLOBAL CONSERVATION LAWS AND MASSLESS PARTICLES*
G. S. Guralnik, † C. R. Hagen, f and T. W. B. Kibble Department of Physics, Imperial College, London, England
(Received 12 October 1964)

Jess Wade is amazing, and it's my absolute honour to be one of the more than 2000 women in STEM whose wikipedia page she started: mymodernmet.com/jessica-wade... 🧪🔭👩‍🔬

Meet the Physicist Who Wrote Over 2,000 Wikipedia Biographies for Women in STEM

After noticing a lack of entries on Wikipedia for incredible women throughout history, this incredible woman decided to take matters into her own hands.

A student on TikTok has been documenting her journey with a professor who “wrote” the anatomy textbook and it’s all a bunch of AI hallucinations.

She’s saying that, understandably, the students are doing super poorly!

Behold what we’re teaching the healthcare professionals of tomorrow:

A diagram of the bones and (some) deep muscles of the hand and forearm. AI says that we only have four digits. It’s also identified a tendon as the median nerve, another tendon as the ulnar nerve, among other issues.

An AI generated diagram of the muscles of the neck. It hallucinated the “ennocleidomasid” muscle, and the “anterior scalpalin muscle”.

An AI generated diagram of the muscles of the lateral thigh. It says that the gluteus Maximus (the big juicy butt muscle) is on the anterior side. It also points to the quadriceps muscle and says “attattment”. It also says that the same structure is the tibia AND the deep fascia of the leg.

An AI generated diagram of the bones of the hand and forearm. This time AI says we have 6 digits. It also says that the radius is the ulnar artery. Among other many issues.

I like how the prompt on a lot of these--after the setup--starts with "Tell me, whoever wishes..." and then the question itself.

Some are simple arithmetic, but q1 is dimensional analysis (might steal it) and q5 is a linear combination with three variables! #ITeachMath #MathSky

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 · 7d

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?
