I am a bartender who hasn’t pursued any science education since high school 5+ years ago. I still come here and am able to follow each of these ideas without any prior context. They are fantastic, thank you for making learning free and accessible! : )

Seems like my social life also obeys the principle of least action

Once in a while, I come across people as radiant as you are which makes me tear up a bit with happiness! As someone who was on the path to being a theoretical physicist a few years back and betrayed that beautiful aspiration due to circumstances, I have a lot of love for Physics and guilt for abandoning it. It has been a lifelong belief of mine that the world need more people of Physics, and you, Ma'am, are helping to create that world by your lucid explanations of complicated physical and philosophical ideas. You have earned yourself another subscriber today:-)
@joepfeiffer1687
Speaking as someone who got a BS in physics decades ago, and who had a career as a CS prof -- amazingly clear and lucid presentation. Thanks!
@thescientist7753
hey there! current physics major here. I'm taking a course on this stuff next semester and I love how simple and digestible you make everything, it really helps me build the foundational conceptual knowledge I need for these courses bc professors tend to skip over that part and go straight to the math without ever explaining the why or how. keep up the good work!

Re: "Physics is a model" Physics is a map, while reality is the territory. We do our best to describe the territory, and while maps can be accurate, and there are many ways to draw maps, they are distinct from the territory. Same with Physics. It's a description of what we think about reality, but it is not actually reality. It's just a map. It's just a model. Great video!
@danilocoutodesouza997
Hey, I'm doing my PhD in Meteorology now and I'm been watching physics videos on YouTube since I'm a teenager. I'm sure you're one of the best. Keep the good work

- Explaining a difficult concept in an intuitive way - Stating you're not smart These are mutually exclusive Please continue with the first!! I love it

A long time ago I had to demonstrate the Principle of Least Action in a Classical Mechanics II exam, one of the subjects of my doctorate. It's amazing how profound this principle is, providing the basis for several conservation laws in physics, including the strongest of all: the conservation of energy. In addition, this principle is also the basis of mathematical structures such as poisson's parentheses that later, in quantum mechanics, give rise to the mathematics of commutators... Currently, in the higher courses of Classics and Quantum that I teach at the Faculty, when I talk about conservation laws, I point directly to the principle of least action. the universe follows this principle mainly for the propagation of light... Excellent explanarion. Nicely done.

I didn't finish high school but loved physics and was a straight A student until year 11. I love learning in general and stumbled across your channel recently. I'd say you do an incredible job of making complex material friendly and approachable. Your animated dialogue adds to the delivery and helps with engagement. I'm certain this channel will continue to grow, serving many students of physics and broadening perspectives and understanding for many. Many thanks for the time you put into this.
@DuckStorms
It is really refreshing to see a physics teacher emphasize that physics is a model and we don't really know the clockworks of the universe but that doesn't stop us from modeling it. Thanks @upandatom!
@onijaradu
I really like your style of teaching physics, keep up the good work!
@antoine-lw5vg
One like for the "Pierre de Fermat" in French :D
@courage936
I am so in love with this video because it is not afraid to ask questions like "does a light particle really choose anything", most physics arguments make unintuitive assumptions and this video is not afraid to tackle them ❤

"I am open to have my mind changed." Beautiful.
@vedi0boy
I’m glad Tom had you make a video on his channel otherwise I wouldn’t have discovered this wonderful channel!
@DavidMcMahon100
Thank you for your clear verbiage and visuals. I found myself for the second time grabbing a screen capture of the math, which flashes on for a second or two. So even the math is accessible if you look.
@mikefochtman7164
One of my favorite 'least action'-like phenomenon is simple soap bubbles. Singular bubbles, the surface tension makes them spherical. When several cling together, the faces/edges start getting more complicated shapes, but it's always the shape of 'least action' or 'lowest energy level'. Nice videos, I just discovered these and currently binge-watching. :)
@kittyhooch1
You asked for feedback and about your viewers. I'm in my 60s and only got to high school physics but I have an insatiable desire to learn and I'd rather watch an educational video than TV. I confess your smile and your accent make your videos easy to watch, but that would only hook me a few minutes. I enjoy your videos because you have interesting topics and a gift for making things very clear. You obviously are well educated but your style is very approachable. What I think is the critical factor though is your obvious passion for the subject. By far the greatest presentations are full of infectious passion that reals me in. There is nothing more tedious than an instructor devoid of passion and nothing more exciting than following an enthusiastic explanation to the next step. Your channel feeds my mind in a joyous fashion. Thank you.
