Why is Mathematics so Unreasonably Effective in Physics ? I Dr. Pervez Hoodbhoy
Вставка
- Опубліковано 3 січ 2019
- "The Unreasonable Effectiveness of Mathematics in the Natural Sciences" is the title of an article published in 1960 by the physicist Eugene Wigner. In the paper, Wigner observed that the mathematical structure of a physical theory often points the way to further advances in that theory and even to empirical predictions.
Wigner begins his paper with the belief, common among those familiar with mathematics, that mathematical concepts have applicability far beyond the context in which they were originally developed. Based on his experience, he says "it is important to point out that the mathematical formulation of the physicist's often crude experience leads in an uncanny number of cases to an amazingly accurate description of a large class of phenomena". He then invokes the fundamental law of gravitation as an example. Originally used to model freely falling bodies on the surface of the earth, this law was extended on the basis of what Wigner terms "very scanty observations" to describe the motion of the planets, where it "has proved accurate beyond all reasonable expectations".

very good lecture.... Mathematics is a language by which we can understand universe..
Nice.... Nice... Kuch Urdu word search Karne pade lekin badiya tha..
Perfect elaboration sir we got a different way to c mathematics
From today I m hoodbhoy . I love you sir i was very confused about world and our living purpose 💓 thank you our living legend
Thank you for uploading the video!!
Waaoo thank you sir ...please upload all the videos of Dr Pervez hoodbhoy whenever he'll deliver any lecture in coming days
dont know if you guys cares but if you're bored like me during the covid times then you can watch pretty much all the new movies on InstaFlixxer. Have been streaming with my gf during the lockdown xD
@Axel Amir yup, I've been watching on instaflixxer for since december myself :)
@Axel Amir definitely, been using instaflixxer for since december myself :D
@Axel Amir yup, I have been using InstaFlixxer for years myself :D
Wonderful lecture sir....Main nay kabhe Mathematics ko is nazar say nae dekha..
Thanks for wonderfull lecture😀😀😀😀😀😀
Good I'm from India and MSc in particle physics
Thanks a lot.
Outstanding stream.
Very nice topic.
I would like to see other videos.
My favourite personality in Physics specially in Pakistan. Have you guys noticed that he stammers a lot while speaking. This shows that his thinking power is far beyond his speaking power. Even his tongue can't go along swimmingly with what's going on in his mind.
Hamza Målîk Looks like it's not stammering . He is trying to explain physics in Urdu where as he thinks those complex problems in English.
Beautiful!
Great leacture. ADMIRABLE Prof
Our brilliant asset !!👏👍
What a wonderful professor!
Well illustrated with insightful examples! In my experience, complex numbers have been useful but not absolutely necessary. For example, Maxwell equations can lead to electromagnetic waves, whose amplitude can be represented by A*cos(wt-kz) or real part of A*exp(iwt-kz). The mathematics is simpler when we multiply complex exponentials instead of trignometric functions. But it is not necessary to use complex numbers to derive real results.
Very comprehensive and informative lecgure
Watching again and again Thank you sir
Great lecture sirr....
Sir, you are mind blowing ! Mathematics is invented but we have to first define what is an invention. An invention is reproducing something by using the laws of nature and the structures of nature. It is just a language of the physics and of course physics is the basis of all sciences !! Physics is the knowledge of the existence. No nature means no physics and therefore to describe the structure and function of the existence we need mathematics. Existence is built in mathematics and according to Max Tegmark all the existence is matter which is written in mathematics!!
Great Effort
Great lecture
Great video 👍👍
great lecture
very good
that is right sir physics is nothing without mathematics
Two wings of the same bird.
Our universe is written in the language of mathematics
Thanks Doctor learning @50 the something that missed. Namaskar from India.
When this lecture was deliverd?
Friday at 2.30pm
A perfect video
Lovely
He is just brilliant
Lovable
impeccable
maja aa gaya. gazab samjhate hain parvez sir.
Excellent presentation basic to think advancement. It is open for creative student. Yes the god having superior ability to develop a universe as a balance. The Hudhuboy is brilliant brain in education . I have respect. And regards for him. Great work he has been done in his field we should learn from him to transfer another generation for thinking further advancement to discover the god universe.
please yar QAU ky physics ky lectures upload kr do
Okay... Lakien time lagay ga kuch!
String theory raveup every things sir, even quantum principle not goes beyond it. It much complex than any other.
Great
thanks
nice
v nice
its pity there is no English subtitles
Niceeeee.... 👌👌
Nice
Nice. Agr mujhe dosra jnm mila to men physics zaror prhon gi
48:08 solving Schrodinger's equation for entire cell 😅
I studied about shrodinger's equation in grade 11th and 12th
i am a fan of sir but very sad 2 see the no. of views
I love mathematics
..really pi is so special and strange dimensionless constant....appears in so many equations
35:40 glad to know some kids tend to know the stuff.
I am 75 and deeply interested
اسی حیرت کی وجہ سے میں فیل ہو گیا
Physics is not only mathematics but physics based on experiment.
can u upload lectures of BS Physics
Okay... Lakien time lagay ga kuch!
اتنا انتظار مت کروانا کے میری برداشت کا پیمانہ چھلک پڑے
Abhe to meray apnay paper start honay waly hain...
Inshallah jald he upload ker dien gay...
Hi...what do need about physics
Mashallah great efforts and guidance. Please try to touch some other subjects also
such as modern physics mechanics and solid state physics
Okay... Lakien time lagay ga kuch!
14:00
Stay happy with the blessings of God
Urdu world we r not getting exactly, sir
Mathematics is my favorite subject means my first GF 💓😂
Math is indispensable ! I won't call unreasonably effective! Reason is it's all quantitative . No law of physics can be understood without Math.
37: 33 😅 knot theory funny moment
I am strongly disagree with you sir on the matter of discovery or inventer. Let me clear my opinion why i say that, Newtonian gravity can't explained the einstine gravity concept. But einstine can explain newton. So those principal discovered in nature, it be exist before newton and einstine. It's our problem we can't understand them. And second we are prograssive with scientific, at newton time our understand moreover on classic, then we further goes with time and accept with quantum principle. Let an example set of (1-10) digits are exist with set of (1-100) digits but vice versa are not whole truth. same way like (1-10) are classic and (1-100) are quantum.So In mathematics inventing word cann't be used, because it before we understand it.
I am atheist.If u r Hindu and u believe in atheism it's allowed , u believe in one God it's ok, u believe in multiple gods it's ok, if u hate God it's okk.
Though being oldest religion and having various things like earth is round, earth rotates round the sun, oldest calendar panchang, Hanuman chalisa explains earth to sun distance which is almost close to science.
Sanatan Hindu books like vedas r proof that it's for mankind! Vedic maths, Ayurveda, yoga and many more..
God is constant, science is also contant in whole world . Then god influence science prove

@@zohaib1537 And since you are Muslim, the credit goes to you directly. All Muslims are no. 1 and better than the rest of the world and the world should follow us.
First time i understand all these concepts wen i am in my fifties😀
I was expecting this lesson to be delivered in English, but the Professor 👨🏫 did the otherwise. hmm 🤔
Bro, language is midium of obtaining knowledge.language is not knowledge.
@@alokpandeyb Language plays a crucial part in understanding the concepts. Without language that is known to someone, the knowledge is futile. I do understand if the students in the lecture are not able to decipher the language, but they know; thus, the professor is supposed to teach in English in that particular scenario. What you are saying is a general thing. Got it!

Mother tounge mein zaada acha sa baat smjh aati ha, is lya Urdu smjhna waala students k saamna urdu mein lecture daana zaada beneficial ha.
Teaching ka purpose students ko saari baat smjhana ha, na ka teacher apni English chaarta rha
@@Ahmad-yi6d You should have read the message with open eyes before commenting. I said 'expecting' not it must be. Yup, I agree with what you mentioned: the audiences' language acquisition and comprehension must be considered.

میں نے آنکھیں، کان، ناک، دل، دماغ کھول کر ہی بات کی ہے اور میں نے آپ کے موقف کو غلط بھی نہیں کہا۔۔۔۔
لیکچر بالکل انگلش میں دینا چاہیے، اگر سامنے سارے انگلش کو سمجھنے والے ہوں۔
ایک تو لیکچر کا موضوع مشکل اور پھر اس پر اگر انگلش کا تڑکا لگا جائے تو بات پلے نہیں پڑتی۔
I have great respect for all as opinion. Let me clear as a student of a Muslim that Quran all books are the message to the world human and jinn that creation of life then birth of life and death then again life after death this miracle of god . So you can say warning sign . You can not say that no one tell us the truth. This is god promise the truth will come minimum one time in your life. So yo can not say I am innocent, don’t know . So bottom line further journey is going on
Kaya sir kuch bhi, we make piramid using geometry, is this not experimental proof of those theoram? Mathematics like soul who run entire body, but not visiable with physical reality. But his uphold the real causes to be happen.
Itna accha professor itni bakwas university me hai ise to galgotia ya fir uske jaisi kisi aur uni me hona chahiye.
Galgotia toh lund university hai iit bol
Have you any dot about mathamtician! A true mathematician like Ramanujam, Perlaman and so on are real person who understand nature and intract with them. Common people can't understand them, but what they are understandable by self.
Stupid
You are just promoting your own mathematicians like Ramanujan, Hoodbhoy is a mathematician, he knows more than you.
@@hamzarefik7779 First of all man Hoodbhoy sir is a good instructor of physic, He is not mathematician. I am also read the paper of Hoodbhoy sir, are you ever read his research paper? They do extensively work on quantum physics specially Nuclear physics. I am really appreciate his work in that field. But comment on mathematics is very immature!
For you information Go on google and search seven Millennium prize problem, one of the problem is solved called Poincare conjecture, just try yourself to understand solution. Check your brain capability, not let take it on ego! Without math every thing null to understand.
@@youtuberate35741 Great! so probably you are a physicist or physics student, I think you should go to high school again, because don't you know that a Physicist is also a mathematician, and for your kind information he spent 10 years at MIT He not only just do PhD in nuclear Physics but MS in solid state physics and many undergraduate degrees in MATHEMATICS and electrical engineering. He is a physicist, a physicist also study mathematics, because mathematics is the language of Physics. Moreover, he has been teaching physics and MATHEMATICS at Quaid e azam University for 43 years. and currently he was holding ZZ and Zohra Distinguished professorship of physics and MATHEMATICS at Forman Christian College.
Oh bhai, itni basic cheezon mein kyun time zaya kar rahe ho. Agar kisi uni ke bande ko bhi ye batana ha to bhar mein gaya wo. Fsc. mein isse zyada pata tha siwae ek Integral wali example ke. Agar teacher na kehte to is pe time na zaya karta.

There is no 'Akhari' Kitab in sciences or mathematics. There is no last teacher, paigambar or guru in sciences which include life sciences. Religion is nothing but a laboratory of life science. Its evolution and discovery. So certain beliefs needs U turn and correction.

you know we Muslims lost our legacy mhmmm due to certain reasons you can refer to the Muslim scientists from 9th to 13th century
Unfortunately the title is "reasonably" misleading and the presenter doesn't know that mathematics is not based on mann-gharat (من گھڑت) stories (what he is telling or probably always tells!), instead it is based on 100% precision and logical arguments. Without going into detail one can even see his lack of knowledge through his discussion on Andrew Wiles, who NEVER received a Fields Medal. His lecture also reminds me a tale of 'blind men and an elephant'.
