Lecture – 1 Introduction to Quantum Physics;Heisenberg”s uncertainty principle
Lecture Series on Quantum Physics by Prof.V.Balakrishnan, Department of Physics, IIT Madras. For more details on NPTEL visit nptel.iitm.ac.in
Episode 5 of In Search of Giants: Dr Brian Cox takes us on a journey through the history of particle physics. In this episode we learn how particle physicists have developed a theory that can explain almost everything in the universe in terms of just 12 particles. This film is part of a series originally broadcast on Teachers’ TV (www.teachers.tv The series was made with the support of The Science and Technology Facilities Council (www.scitech.ac.uk). www.lhc.ac.uk – Official UK LHC website for public and schools. www.particledetectives.net – School resources on the LHC, how science works and particle physics. Films produced and directed by Alom Shaha (www.labreporter.com).

Where can i find videos related to Sound Engineering? ;D
Delighted to see the video lecture by the great teacher Prof. Balakrishnan. But is it no true that uncertainty principle is derived from commutation relation; not from Schrödinger equation.
Shaji
Can anyone explain where neturons come from? or How neturons are formed
i’m here cos sheldon’s cool
@123market456 thats not true… there are certain topics that are much better explaind through pp slides, animations etc.. like biology for instance… even certain topics in physics are better explaind that way like the double slit experiment…etc. since quantum physics is more abstract in nature its easier to understand it mathematically.
@123market456 Actually, learning styles theory says that different methods are better for different students, hence the possible advantage of a combination lecture (for auditory learners), graphical components (such as pictures, video and text on powerpoint for the visual learners), and laboratory exercises for the tactile/kinesthetic learners. One issue arising from trying to accommodate all these learning styles is that sometimes the teacher doens’t balance them well.
Thank you sir for an excellent explanation.To hear a highly educated professional professor say that we do not know 95% of what could possibly be known in our own universe is very refreshing.Science,like any other subject, knows very little about what they think they know.The majoroty of highly educated people seem to think what science is a know all end all,and as with everything in life we are all just begining to see.
Could Heisenberg Uncertainty Principle be the same uncertainty that the observer will have with any future event? Could time and the geometry of spacetime be continuously formed by the momentum of EMR or light form one atom to another? There is no understanding of time in modern physics or why we have a future and a past. Could this be why we have the paradoxes of QM?
OOoooohhhh Sagghhhaannaaa
D WHOLE OF QUANTUM PHYSICS ND MUCH BEYOND IS ALREADY EXPLAINED IN FULL DETAILS IN VARIOUS SCRIPTURES OF HINDUISM…..
very few ppl know that max planks father was a religion scientist who explained planc about d intro o fquantum phyics particle called photon in his dream……which he has stated in his autobiography…..
jai hind….
after nine yrs of unsuccessful research of warner heisenberg along wid bohr….he visited india 2 meet rabindranath tagore who thru just a few qoutes of bhagvadgita gave him the concept of uncertain trajectories of electrons……
“The failure is on the part of the English language” at 37:25 . This was the most unpredictable answer, which he explained so beautifully. Hats off to him.
@ephipi
you retarded, low-IQ, faggot, go watch Justin Bieber videos. Physics is for people who can understand it.
@LogicalFlawDetector
Yeh! Whatever …. DICK.
@ephipi
whatever, dolt!
@LogicalFlawDetector
Sorry to hear that. Thanks for the update. My favorite Physics teacher of all time and most inspirational person was Richard P. Feynman.
dolt – A mental retard who is clueless not only about current events, but also has the IQ level of a rock.
Pretty nasty comment there.
Don’t know how to respond to that, … yes I do, but you’d have to be standing in front of me. Anyway, I can assure you I have quite a High IQ.
@ephipi
I am originally from India, you dolt. Actually most teachers in India are retards. They will harass you, exploit you, and do anything to you, based on skin color, caste, and gender — all of which go back to the old days, when the higher caste Brahmins recruited students to do their household work in payment of tuition. This practice — of exploiting students — continues, though in a less severe fashion, to modern times.
Most of my American teachers are bad ass!
@123market456 That is because everyone learns differently, Some people could have things explained to them and learn, others need to see a visual representation. This does not make one smarter or dumber. I was forced to drop out of school at 12 yrs. old when I was in the 6th grade. I went back to school at the age of 18 at which point I had done a lot of studies by myself. Today I have a Bachelor in IT and am working towards a Master’s Degree. But till this day I am not able to study in school.
It’s not impossible to measure or define momentum and position instantaneously. Think of two magnets attracting. It is possible to calculate the attractive force between them, friction and other variables if necessary, and from that determine the speed at which the magnets are moving toward each other, as well as distance relative to each other. Can someone tell me what i’m not getting here? This is a new interest of mine so…yah sorry if i’m just being a noob or whatevs
We used to consider Balki as the God of Physics. He taught us physics at IITM in 1983. The coolest professor I have ever met in my life. I have been tripping viewing these lectures after ages….These lectures are IMHO easier to comprehend than my other idol Feyman’s lectures
This is a wonderful professor with a very clear and deep presentation. Thank you for sharing.
Sir, I am a physics graduate of BITS-Pilani. Thank you for this most enlightening lecture. This has been one of the best hour’s of my life. I can guarantee that each one of the students in your class is truly blessed. Thanks a lot for uploading this amazing video.
The reason why we, the U.S. don’t have instructors of this caliber is The Heritage Foundation and similar so called “Think Tanks”.
“It is some kind of crazy extended object.” I love the expression on his face when he says this!
“It’s not the particle’s fault. Nor the fault of the experimenter.”
Awesome vid. I understand so much more now. Thanks!
This saved me (and probably 120 000 others) about 1.5 h of “transportation of mass” time (Commuting time).
Thank you IITM
Thank you Prof.V.Balakrishnan!
and Thank you Science!!!!!
@Zayin1993 It is well over 9000…. kph
@shep312 OLD
@shep312 this comment is epic!
12 sub atomic particles ! fuck! change your stupid more info section. misinformation spreading fuck
WHAT!!! 99.999999 % the speed of lighT!!????
THATS!! near theoretical impossibility!!!
I’m sooo psyched for the LHC!
@cheasea
Absolutely correct!
@sidewaysfcs0718 I agree, but really, I think we should focus on everything. We’re a species of information, of discovery, that is what we do best and that is what we should focus on, only problem, we’re still too dumb to understand that we yet don’t understand. If our focus as a species was to discover the beauty of existence, instead of trying to take it for our own individual selves, then there would be no desire of hoarding it all, allowing us to experience the full depth of being
@jockedahl123 thank you
@shep312
TURBOPUNS!!!
the world of the large , the stars , galaxies and stuff …
its limited to us …we have a horizon ..we cant see past the cosmic microwave backround …for several reason but the main one is the expansion of the universe
but the world of the small …is still strange and misterious to us. so i think its more important to discover everything we can about how particles work before we think about big stuff again.
true…….i’m a fraud
@shep312 not new
Carl Sagan sucked balls.
The awesome Carl Sagan was replaced by this kid….
Oic.. Sry. I thought that you were trying to be a perv.
i meant to say that mass is an illusion
Someone should break your fingers
@violentauntie
Classical mechanics (the old laws) explain very accurately our world that we usually see – fairly large sized objects and low speed. When the speeds become sizeable relative to speed of light, classical physics completely fails, and we need a new model – relativistic mechanics.
At extremely small sizes and low speeds we have quantum mechanics. At small sizes and large speeds – quantum field theory.
None of them is right or wrong, they just fit reality better at that dimension.
newtons laws arent wrong ..they just dont explain in detail how gravity works ….
this is so exciting!
That is a pretty big hadron
,ass is an illution
Interaction means coupling of two or more fields in the Lagrangian or action density of a quantum field theory.
And the standard model of particle physics couldn’t possibly be barking up the wrong collider. I was debating ‘what the words mean’. By no causal, you mean phenomena that spontaneously exists independently of any and all other phenomena? Must be magic. You forget you are talking about academic physics in relation to a program made for your gran. You cannot reify the sci fi dreams of your childhood. Go watch Time Team schoolboy.
