Channel is so underrated it’s insane

[@maximusideal]

This channel deserves more views imo.

[@mindmaster107]

Best you can do is just share it :P I don't plan to keep these explanations to myself. If your university professor is chill, you could send an email with this video to help them with their lectures.

Love from Bangladesh 🇧🇩 The channel is gonna blow up soon..

[@满地走]

Stumbled upon your channel when i was browsing the “Chemistry” section a few days ago, and although i don’t understand most of what you cover in your videos, there’s something really mesmerising that kept me watching them from start to finish. In fact i love your videos so much that now i regularly listen to them as i do *real* natural science , i.e. chemistry ;) Jokes aside, keep up the good work!

[@满地走]

btw i agree with the other commenter on this video, please never ever get rid of the lil guy in your videos, i’ll literally cry if you do so

[@mindmaster107]

Oi Physics is the real science :angry_face: Thank you so much! I won't be ridding of that mascot any time soon, so don't worry!

[@clickbaitking6770]

Great video! I’m keeping an eye on this channel, such quality doesn’t goes unnoticed for long…

[@mindmaster107]

Thanks for the praise!

[@jdrmanmusiqking]

Yo you are clearly tapped in. Keep being great homie

[@Dekoherence-ii8pw]

19:30 So gravity is an "unremoval fictitious force". Nice! 🙂

[@mindmaster107]

Absolutely!

[@pizzarickk333]

Great video! Can you recommand me textbooks for studying modern physics from scratch?

[@mindmaster107]

Young and Freedman’s textbook on university physics is quite a good starting point for general stuff, and Griffiths’ electrodynamics is good for both the maths and electromagnetism material. I hade a video on what to focus on during self-study, (see how others solve the same problem, and get comfortable with making alternative explanations) which you can watch if you want more help. Good luck!

Amazing video, thanks :)

When Einstein came up with relativity, he had to be on LSD. Change my mind 😂 Shoutout from South Africa

[@sachinbhadarge8239]

Please do one for general relativity

[@mindmaster107]

I plan to in the future, but that won't be for some time. Meanwhile, eigenchris has a great series on GR, which I have found very useful.

[@StephenGillie]

Earth is roughly level, and its mass curves spacetime into an oblate spheroid, the Moon's geodesic into an ellipse, and time into gravity. Things which are truly flat - such as the LHC's 4 km arms - have to be built with what seems to be a slight bow in the middle, when engineered to be level.

[@justrandomthings8158]

Just so you know, pease never remove the sprite. That’s like half the reason I watch lol it’s so cute 🥰

[@mindmaster107]

Omg thank you yes, he is adorable.

[@Dekoherence-ii8pw]

NOW DO THE TWIN PARADOX.

[@sampson4844]

So... "Real" acceleration exist??? But how is that possible since the whole point of relativity is to say that there is no absolute reference frame? How can we say an acceleration is "real" if no such reference exist?? Not talking about GR only in SR flat spacetime. Maybe the answer is in the math? But obviously I don't understand the math😅

[@mindmaster107]

No absolute reference frame doesn’t mean velocity and acceleration don’t exist, but that the amount depends on who is observing. When I meant by “real” acceleration, was there is no way to set it to zero with only reference frame changes. This is the hardest video by far, so don’t be disappointed in yourself. I made the video relaxing to listen to, so maybe give it a rewatch after learning more on your own and it might just click.

[@sampson4844]

@@mindmaster107 🥰thanks for your reply. I am not trying to say vel. and acc. doesnt exsist, i just can't accept the way people resolve the twin paradox by saying "acc. (or proper acc.) is absolute" and "the rocket twin feels the force", since without a static reference(like the stars in the universe), it is impossible to differ who is actually acc. and, "feel" is subjective. That's why I asked about the "real" accelaration thing. I just think that acc. should also be relative. I am just so confused. Maybe you can explain it better in your videos about this?

[@mindmaster107]

Acceleration isn't relative. There is no reference frame that can remove the gravitational force. Velocity can always be removed via transformations. Acceleration might not.

[@sampson4844]

@@mindmaster107 that still don't make sense for me and I still have a lot of questions. But I will figure those out myself since it is impossible to ask all of it here XD. Thanks a lot for your replies.

[@mindmaster107]

Good luck on your own journey!
