I'm only discovering this on August 18, 2023, but I have to say, this is the most interesting and amazing explanation of the difficult but useful pragmatic utility of learning from Wikipedia. Often I read dismissals of Wikipedia as completely useless. This guy dispels that notion. However, it is also clear that when you use Wikipedia, you should also have a solid foundational knowledge and experience in the field you're researching. That said, Wikipedia and sites like RU-vid with instructional and tutorial videos can be extremely useful in learning the basics of many skills that will lead you to increased knowledge and skills. I love the internet so much. Oh, I thought I might add how I came here. I was looking up how to pronounce some Korean words and names. One of them was 김관영, Kwanyoung Kim, and following some of his recent scholarly works, "Unpaired Image-to-Image Translation via Neural Schrödinger Bridge." Then, Bingo. I highly recommend subscribing to this channel. What are you doing nowadays? Thanks Parth!
Answering to your weekly question: From past few weeks I have started to learn drawing. As a child I was very interested in drawing, but somehow I didn't get to learn anything. But now as I have completed my graduation and have access to better resources like internet I have started again.
For younger audience in secondary schools , the biggest bugbear is understanding 'Calculus '. Please make videos on 1.Pre-Calculus 2. Introduction to calculus ie. Concept , functions, derivatives , infinitisimal , rate of Chang ,limits, differenciation , differentials ,derivative , integrals, integration , symbols and nomanclatur . Just to clear the cobwebs and get started .
You are awesome. Thank you for helping others get closer to physics. It is immensly interesting area of knowledge and it is great to share it with all the ppl. Wishing you a fruitful day. Looking for your next lessons. :)
I've really enjoyed your videos; they're a recent find for me and coming back to learning after many years they've been inspirational. The Wikipedia article is totally off putting.
You perfectly summed up my frustration with Wikipedia science pages. Simple Wikipedia is not much better, also creating rabbit holes, but just talking to you like an idiot. You might get a lot more views if you started a series "[X} for beginners", with "FOR BEGINNERS" in the titles, and continued explaining things in common English.
I just finished studying calculus 3 and I'm hyper, love physics because of math. Btw this is what I was the most proud of, I learned calculus 1 2 and 3 as a rising junior over the summer hehe.
Hey Parth, can you make a video on why the speed of light is essentially the speed limit of this universe? I mean, through the internet I at least know that it's basically since time stops moving for that system and an infinite amount of energy is required to accelerate it further, but why this specific value? Also, if we did manage to exceed this limit, would it be possible to go back in time? Eg. Tachyons
@@ParthGChannel though others may believe (myself included) that it's simply because we haven't worked out the reasons for those values yet, and that they may be derivable from purely geometric constants such as pi, e, phi perhaps... obviously this geometry would not be simple, and would most definitely involve projections to and from some higher dimensions (E8 anyone?) but until we produce a sound unified field theory it's no real use trying to look deeper yet...☺
Fortunately, your QOTW was not too tricky for me - I received my undergraduate degree in Interdisciplinary Studies, and have begun preparing for a graduate astronomy program!
Quantum mechanics isn't necessarily just for the "very small" anymore, as buckyballs and larger molecules (on the order of hundreds of atoms) have now been used in the double slit experiment. (Spoiler alert: yup, still worked just like photons and electrons)
I have a quick question on this, does the quantum state describing the wavefunction of say an electron take into account how the measuring equipment will affect the probability? So say you're using photons to detect the collapse of the electron, if you have a greater photon density in one area than another, would this alter the probability of the electron being found in that place? And so, considering that the measuring equipment is itself quantum in nature, is there a way to combine the states of both the observable and the observer to attain a more accurate calculation or is this not necessary? Thanks
The wavefunction by itself doesn't contain any reference to the effect of the measuring device on the system. You could take it into account by modifying the Hamiltonian of the system, but usually this is very complicated since the measuring device is usually a very complex system which I'm almost certain you won't be able to describe easily in a quantum mechanical way. Also, when you measure the system you modify it, and it transforms into the state that you measured (this is the 'collapse' of the wavefunction') . I'm not 100% sure of having explained it correctly, but if you are interested you could look up about 'measure theory in quantum mechanics'.
Thanks Parth , that was a really helpful clarification after wandering wikipedia for ages. Could you please bother giving the same treatment to Matrix mechanics and Path Integral formula which were just below the paragraph on the same page ??
Hi bro As you said us that derivatives are the rate of change w.r.t time and Integration is the way of calculating area under the curve, so how those two are opposite of each other I mean Derivative of X²=2X Integration of 2X= X².
Thank you for telling me why wikipedia is crap. I never really understood that, it seemed fine to me, but I am not a highschooler so I guess thats why.
Quantum mechanics have yet to found a way to explain gravity, therefor it can not describe systems big enough to be affected by gravity. That's the only thing eluding Quantum Mechanics right now, that's why GR (General Relativity) is still so important.
Hi Parth. You are really good not just explaining but in creating interest in science. I am engineer and entrepreneur (check out www.gtd.es) but I have the soul of a scientist and my free time is dedicated to studying physics (classical and quantum). Congrats!!
Also, the function in a linear differential equation can be non-linear. It's the relationship between the functions in the linear differential equation that need to be linear. You shouldn't act so arrogant if you are not sure what you are talking about
I really appreciate the information, but as a neurodivergent person, the constant clapping and snapping made it really hard to listen to, and to focus on what you were saying.
