    Path integrals are so cool. When I grow up I want to be a path integral.

      Take the path of least action and you should get there.

    Just wanted to leave this question here, if anyone can give me some pointers it'd be greatly appreciated. So I'm currently a Junior in high school here in the US and I'm interested in going into astrophysics. I've been debating with myself on whether or not I should really go to uni here in the US. "I'm not very wealthy" is an understatement for me and I worry I wont be able to get into a decent uni for my undergraduate degree, or graduate degree for that matter. Another thing I'm worried about is, even if I do get into a nice uni with the help of financial aid and I get my bachelors, masters, and PhD, I'm worried I'll get into a position that isn't well funded; that is if I can get into a position at all with how things seem to be going for pure science majors in the US. So, what are my options?

    So wait, that means to say separated events in classical term is not really separated in quantum term but you have to consider all path that it did take to give a accurate prediction? That sound insane, how would anyone do something like that?

    Didn’t David Hilbert have something to do do with least action when working on Einstein’s general relativity?

    • @bunklypeppz
      @bunklypeppz 6 ปีที่แล้ว +1

      The principle of least action predates the Feynman path integral formulation. It is one of the cornerstones in terms of mathematical formalism for all of modern physics, from classical mechanics to pretty much any subject in theoretical physics. It essentially has to do with the fact that the expression for the action for any system can be optimized through the use of the Euler-Lagrange equations from the calculus of variations, which is analogous to the process of setting a function's derivative equal to zero and solving for the variable in elementary calculus; the solution to the Euler-Lagrange equation describes the path of "least action". I think what you are referring to is the "Einstein-Hilbert action" from which Einstein's field equations for general relativity can be derived.

    Your voice clarity and smarts are the reason why I watch your series. Talking ghetto isn't smart it is annoying and degrading toward human progress. If you are applying for a job in Hollyweird then you probably want to sound uneducated but otherwise it is bad practice. Sound smart and you will be treated as such. Thank you for making the world a smarter place to live. Will be watching much more of your content.

    This wasn't even mildly challenging , well at least for me anyway. When you have an intellect as great as mine, mathematical computations at this level are the equivalent of basic arithmetic for the lay person. My IQ has intimidated even my professors. For you see I am a Ricardo and Mortimer fan and therefore nothing can match my intellectual prowess.

    • @maglight117
      @maglight117 6 ปีที่แล้ว +5

      To be fair it takes an altitudinal IQ to comprehend, nein, fathom Rick and Morty. The humour is extrêmement subtile, and without a doctorate degree covering Bell inequalities, micro-lattice structures, and Schrödingerian quasi-contradictory quandaries et cetera (basically common knowledge among the top 10.3% among the world's best theoretical physicists) most of the jokes will evanesce or float away like Kantian noumena vis-a-vis Kantian phenomena, in other semantic units AKA words to plebes, as they say in some ethno-linguistic communities, but I digress: ありがとうございました. Furtherthus, to neologize a neologism henceforth, Rick’s existential-ideological naysaying, which ITSELF located within/via Althusserian/Foucauldian poststructuralism along the subversive-critical lines of various neo-Marxist-Leninist-Maoist analyses - his tacit (cf. Polanyi) schemata appropriates affective resonances from Narodnaya Volya literature, AKA 네 엄마는 너무 뚱뚱해. The fans understand this 陰毛, as colloquially known (excepting for Gettier cases), to quote the Chinese media scholar Jean-Claude Baudrillard: "Un jugement négatif vous donne plus de satisfaction que d'éloges, à condition que cela ressemble à de la jalousie" ; they have the Intelligenz/くそ to truly (BUT WHAT IS TRUTH, cf. Sura 2:140, John 18:38) appreciate the Aristotelian-Thomistic-Hegelian synthetic a priori interpenetrative dialogic concealed within and without these tokens of jokes, to realise that they’re not just totalitarian HAHAHAs :D in a post-postmodern world of hegemonic HUHUHUs :( - light-hearted Chopin to your heavy-handed Brahms, if I may, no pun intended - they betoken something deep about Heidegerrian Dasein (cf. Mahabharata 5.39.58) through which we can, in the words of the poet William Wordsworth, 一个巫师从来没有迟到,他总是一个有力量的人 (Yīgè wūshī cónglái méiyǒu chídào, tā zǒng shì yīgè yǒu lìliàng de rén for those who aren’t fluent in Korean).
