I’ve found myself sharing your videos with physicists of all levels of expertise-from beginning students to long-time professors. Your videos are not only a gift to students, but they are also an inspiration to anyone interested in physics pedagogy. I hope you enjoy making these videos as much as we enjoy watching them.

This is what the internet and KZfaq should be used for not the dumb stuff of social media.

Yay! I'm biologist and im learning distance metrics, including geodesics as a part of a proyect that involves tensors and n-dimensional spaces of proteins. With this video I get a clear view about geodesics

Favorite science channel on the site honestly

It is insane how well presented your videos are. Please keep this up! :)

You're the Geodesic to my Relativity, ScienceClic

I love that you explain the concepts clearly enough for most everyone, but also include the equations for those who wish to go further. Thank you for being "au-dessus de ma tête, mais pas hors de portée" (above my head, but not out of reach).

I just watched your entire general relatively series and have never had such a strong understanding of the material. You also addressed how a 5th dimension is not needed to address gravity in your better general relativity model, which had been nagging my understanding of that concept for a long time. I have so far yet to go but feel invigorated to press forward thanks to you. I noticed you've been using the same song on every video for the last several years. I'd be absolutely willing to compose a custom soundtrack for your videos completely free as thanks for the work you do. Feel free to reach out any time :)

This is the best Physics channel by far. The concepts are explained in the right amount of detail

Showing that following the same latitude is not a geodesic is more clear near the poles. Great video.

I just found your channel and I'm blown away by the quality. Videos like yours inspire me to continue grinding through the hard parts of university to one day be able to wholly understand the beauty of the cosmos.

This video is simply stunning! I'm amazed at how well you've condensed these equations and how intuitively you've explained them. I hope your channel absolutely explodes in popularity. Great job :D

By far, ScienceClic is the most precise on the subjects of physics in the internet. Keep up the good work.

Alot of this knowledge I've already viewed in other videos, but the clear step by step breakdown is a joy to watch/listen to. Great content!

This channel knows the geodesic to my heart

Incredibly well explained and the visuals make it crystal clear. Thank you very much.

The giant connection with relativity at 6:14 blew my mind. These videos help me so much understanding general relativity because of it's excellent visual and audio information. Excellent channel!

I just LOVE your visualizations... They are clarifying so many things a textbook or a simple PowerPoint presentation can't really answer. Thanks for all the effort! Your channel is one of my favorite physics channels.

Please keep these videos coming. The narrative is so awesome and clear-

As usual, on point presentation and brilliant visualizations. In particular, with the image of the apple moving through space time it's kinda fun to imagine yourself doing that while being pushed *away* from your geodesic by the chair you're sitting on. This is quite different than the usual notion of being *pulled* down by the earth, but more accurate.

Absolutely stunning videos. Just keep making them!

Always brillant. I look forward to your videos. Thank you for the time and effort to make these animations. 😊

This channel is pure quality. Simplicity at its finest. Thank you very much for entertaining us.

To the author of the video: hi! I watch the videos late at night, and the full white screen actually made my eyes water up, and hurt. I thought you could actually invert the colors, and the video would still work and look great, and it wouldn't be so hurting on the eyes. Thank you for the great videos! I subscribed and clicked on the bell 👍

Incredible quality. Just amazing.

The gravity of this channel will not allow me to leave. Bravo.

Best visual learning channel on KZfaq hands down

Thank you! These are very informative and extremely well-designed illustrations!

You did magnificent job to explain General Relativity. Although books plays important part in course but your work has reduced the time and energy of learner which he or she have to spent during Reading. I could understand importance of Riemann Geometry in General Relativity only beacuse of your videos

PBS Spacetime: Best topics and explanations but in a monotonous lecture without good graphics Science Asylum: excellent topics average graphics but good humour and interactive... sometimes too "crazy" stylewise Science Clic: Greatest visuals awesome narration...but too infrequent

I was literally arguing with my friends about the path a plane takes, yesterday. Great video and thanks! Now I can refer them here.

That part about a falling apple is simply superbly described.

I think it's worth mentioning that two identical objects moving in curved space-time with the same starting point will follow different geodesics depending on their initial speed. I mean, it's kind of obvious that objects thrown at different speeds will end up in different places, but it also seems really counter-intuitive that your "forward" direction depends on what speed you have. In space, the forward direction that you see with your eyes, which is actually a direction of a light-speed geodesic, is different from the forward direction you are moving.

Genius, Geeez I would love to have such presentation 30+ years ago! Animation and modeling is superb! Thank you!

Awesome video, as always! Thank you!

Yes! You finnaly back, LOVE your content

I get excited every time you upload

Thankyou for Expanding my mind and Appreciation of Source xx

This is the best channel I need satisfying my curiosity very well!

Yay, welcome back ScienceClic!

I love your videos! Thank you for your hardwork and creativity 🥰

Thank you for all the efforts, It totally worth subscribing this channel!

S.C.E I'm always working when you're uploads come up, just saying that I appreciate this channel as much as people who comment earlier than me

Superbly done! Thank you.

This is the BEST science channel on KZfaq!!!

All videos are awesome And explanations are like Cristal clear.. Plz make a project on higgs field and higgs boson. Thanks 👍🏻

Your voice is something else mate, there's not a lack of physics or math channels but honestly the way you speak sets you apart, same reason Mat from PBS has a lot of success aswell, keep at it

I wish I saw this before my cosmology course. Great video!

I think these sort of visualizations are the best way to help people understand the latest scientific understanding of space and time. I'd love to see you cover the visualization of Earth's gravity field (including the field inside the volume of the Earth).

This wonderful article is smooth and gentle, the very best way to wade into cold water...😎

Amazing as always. I can't wait for more 😍😍

Amazing as always!

This is amazing stuff. Thank you for visualizing some of these difficult concepts. Honestly I think that schools should talk about this stuff when they are talking about Newton's First Law. If we all were taught that the "straight line" that Newton talks about is (spatially) what is being curved by gravity people would probably have a better understanding what is going on. Explaining the time dimension would then be a little be easier.

This video is, as always, really great!! Keep it up! Any plans to make a video on quantum chromodynamics?

Oh my goodness I just love it when I hear that music because it tells me I'm about to learn something incredible and this time was no exception I loved every second of it. The music just gives me goosebumps I love it so much.

i have no idea if at the end you were just flexing that you can pronounce that but it doesn't matter, these videos are amazing

Really cool! Very insightful!

Thank you, this is superb. It's going to be shared.

Marvelous video, as usual!

Great job, once again!

Thank you so much! Is there any chance to have an introductory video about noncommutative geometry in physics?

Only here every phisics topic become understandable and accessible to everyone. That's very unique.

2:03 Metrics *do not* give you a grid as represented, tangent spaces do. Metric just gives you a scalar product of vectors in tangent spaces, which can differ at each point of a manifold. And as you presented in a video - in case of immerged manifolds and induced metrics - this has a perfect meaning of distances on a sphere.

This is another in a series of amazing, sophisticated, elegant, accolade-deserving videos that ought to receive recognition beyond just the KZfaq platform. That said, we were determined to find something to be nitpicky about, so here goes 😂 : “…when an apple falls off a tree from a previously motionless state….” **technically speaking** the apple hanging from the tree was subject to a force and therefore already in motion. “…it is because the curvature of spacetime bends the geodesics between time and space…” Well again, **technically** the apple wasn’t on a geodesic to begin with; being held up by the tree meant it was subject to geodesic deviation. There isn’t also really spacetime curvature in this small of a region. The ground is just an accelerated observer; the geodesic paths on his/her spacetime diagram appear to be bending as a consequence of that acceleration. (For there to be spacetime curvature in the vicinity, the distance between geodesics on the spacetime diagram would have to be changing - but even the down-diving lines maintain regular spacing.) However that statement does apply in the global sense, since without curved spacetime there wouldn’t be the gravitational force there to begin with. It’s very encouraging and inspiring to see videos of this quality and caliber out there - please keep it up!

Your videos are gifts.

superb video pure class,, man please continue to upload,, never stop🙏❤

Well explained as always 😊

Wonderful class.

You are awesome man! Thanks a lot!

Great video, as usual. Ants and geodesics, cool!

Thanks for the info

Very Valuable Science video 👍👍👍

Another beautiful explanation that even a layman can understand. This is gr8 ability of you. Each video is very thoughtfully crafted. 👍🏽🙏🏽. Keep posting such gr8 work. Can you plz explain the details of formulae you showed in the video. That ll still further open up mind.

Please just let the animation of the apple get to the ground. Everything is so perfect, just add a little more time to some of these satisfying animations. People love watching satisfying stuff.

great explanation

Awesome Video as always! One question I have is the approximated space near the ant and adding up is like calculus for 3D space? does it follow the same math extended to add another dimension?

Like it how the music changes suddenly ❤.. very nice explanation 🫵🏼👍🏼

Love all of these videos!

After Vsauce and Veritasium, i find your channel more interesting and understandable.

I love this channel. I just realized I saw this but I’m watching it again….

This is a good video! Thanks !

Very very interesting topic!

I've been learning more about non-euclidean geometry in order to gain a richer perspective of the human body. I have an interest in computational patternmaking for clothing design, and I found this. Simply put: My mind is Blown.

My fav KZfaq channel. ❤️❤️

Thank you!! I've been waiting to death for new clip

Great video!

Thank you! Your videos are amazing!

Thank you!

Great videos for learning about physics.

Very impressive explanation ,can you make a video about why mass bend space time

Being waiting for you guys to drop a new video👍🤩

I love how first, it's the happy music, and I think "yes, two ants walking around, I get that, everything's good..." and then suddenly the music changes....

I love your content

Great videos man. Have been watching all of them recently to solidify my knowledge. Keep it up!!

Very nice animation.

Thank you.👍

I know this is "just" a translator-channel, but I don't happen to speak any french (yet), so let me just make my comment here: This channel is amazing! I love physics and the whole content you're covering here. But what's especially nice is that you often show some of the higher mathematics few are actually familiar with, like the Lagrangians or matrices in this particular video. But do you think you could show more of the mathematics, maybe in separate videos or so? I don't know how other viewers think about this, but I think that might be interesting content too.

It's funny, I already studied this in uni, and I have good understanding of everything you mentioned, but I still enjoyed watching the video.

New favorite channel. Thank you! Hmu if you want to make a video on gravity

Very important video !
