- James Clerk Maxwell (1831-1879) was one of the most important mathematical physicists of all time, after only Newton and Einstein. Within a relatively short lifetime he made enormous contributions to science which this lecture will survey. Foremost among these was the formulation of the theory of electromagnetism with light, electricity and magnetism all shown to be manifestations of the electromagnetic field. He also made major contributions to the theory of colour vision and optics, the kinetic theory of gases and thermodynamics, and the understanding of the dynamics and stability of Saturn's rings.
This talk was a part of the conference on '19th Century Mathematical Physics', held jointly by Gresham College and the British Society of the History of Mathematics. The transcript and downloadable versions of all of the lectures are available from the Gresham College website:

he is actually my favorite scientist for some reason. i randomly read his biography because the author (a physicist) said his name was often mentioned but no one wrote anything about his life. what i really liked in the book is his sense of humor : )
Of all the brilliant discoveries in history, I don't think any rate higher than Maxwell postulating radio waves, proving it mathematically and having his insight validated. The world has never been the same since.
One of the true greats.
Maxwell had never died,his theories are with us which make us feel he is alive.He will be remembered upto years of years!!!!!!!Extraordinory James.I am greatly inspired by his work,he is my icon.
Einstein on arriving in England was asked "if he stood on the shoulder of Newton", (as usual the English trying to take credit for everything), Einstein replied, "I stand on the shoulders of Maxwell".
mattsmiddy40 that does seem to explain the first sentence emanating from prof flood's mouth, doesn't it.
Einstein seemed to be a very humble man. He accredited Tesla as being the smartest man alive and says he rode of maxwells shoulders.
What a childish thing to say, mattsmiddy40. Your immature comment on a topic like this says more about you than it does about Newton, Maxwell or Einstein. Greatness doesn't care what nationality you are.
@@TonyEnglandUK Greatness may not care, but those in any given nation do.
@Tarquin The Rotter Micheal Faraday, who came up with the theory
Thank you for publishing this lecture! It is very insightful, and I appreciate the good humor and and winsomeness of Professor Floud.
Great video. I wanted to say something clever about Maxwell and his work, but confirmed my inability to do so after the third attempt. Well presented, and very informative. Many thanks.
Peter Guthrie Tait (1831 - 1901) (3:24) was a Scottish mathematical physicist known for the physics text Treatise on Natural Philosophy, which he co-wrote with Kelvin. He was also an early investigator of knot theory, which contributed to the formation of topology. Tait was an avid golfer and in 1891, invoked the Magnus effect to explain the influence of spin on the flight of a golf ball.
Thanks for posting this. Very informative.
Great talk.
Feynman was so right !. Ten thousand years later when scientists reflect on the most important invention, they will conclude "Maxwell's mathematical model for production and propagation of electromagnetic field (electrodynamics).
comet3bc13 Or he wasn't foolish enough to disregard what could come in the future. I think it is fairly safe to say that Feynman, someone who worked with electrodynamics himself, saw the unifying theory of electricity, magnetism and light as the single most important discovery since science itself.
Very informative. Appreciate it.
Excellent Lecture, superb thank you for Sharing 👍🎓🎓🎓🏆🏆
Great video, very Informative.
Woing-woing-woing! What a wonderful echo we have recorded here!
James Clark Maxwell is one of the most finest physicist.One of his equation is also a realvistic theory and contributed greatly to elcetricity and electromagnetism.
Excellent!
Maxwell contribute amazing wave theory I love it ❤👍👍
By the same token, Maxwell didn't discover any of the 4 equations we now call "Maxwell's equations." What he did was find and make a correction to one of them, then realize the ramifications of the 4 together (namely, that electromagnetism is a wave which travels at the speed of light).
Which were then put into their modern form 20 years later by Oliver Heaviside. An even less well known mathematical physicist
Yes, that is true, and maybe more fundamental, even if not more 'important' for chemistry and so on. Gravity moving at the 'speed of light' , through all mediums, is even more fascinating to me, even though it's the same kind of contraction that requires it. I guess it's easy to think about light as wave/particle, because it's observed like that, but gravity must be both and yet neither gravity wave nor particle are (yet) detectable, even though it interacts with everything.
Too many complaints about stuff left out of this lecture. It was nearly an hour long and the speaker complained at the start that there was two other speakers before him and "they had stolen the best bits". What was missing from this was probably brought up by those other speakers if it was worth mentioning
Einstein: My hair is always disheveled.
Maxwell: You don't have a beard like mine.
He had the best mustache in the history of mankind
I think the importance of the works of such men lies, not just in the potential for application to invention, but perhaps more so in the insight into the workings of nature, that enables others to see even further. We are not far enough along the path to wisdom to rest upon our creative accomplishment, for there lies ahead a discovery that far exceeds our imagination. We stand upon the shoulders of giants, and what we see ahead will make them small again, and we will be the giants. Such is the evolution of the mind that we should one day be the masters of the place which now inspires us to know it.
Interesting observation. The "somehow woven" could be the rate at which history frames proceed.
Maxwells model of molecular vortices and electrical particles has got me wondering. Would a hexagonal configuration also work in a tokomak fusion reactor in stead of a torus?
Ok I randomly watched this today and it's his birthday today, June 13th, coincidence? lol
The man in the picture is not Maxwell, it's Lord Kelvin
It's a very sad thing to have to say this about humanity's rationality (and especially about the social world of scientists) that without Maxwell or someone of his acumen and stature to further it just a bit, Faraday (whose limited education left him without proper mathematical expression of his findings) would never have been recognized as anything but a good teacher.
4 famous equations by Maxwell is just another form of relativistic theory.
That is a picture of Lord Kelvin on the thumbnail, not Maxwell
Professor Flood at his best
Saturn ring photos :
google.com/search?q=saturn+rings+photos
Dear Gresham College, the photograph is not Maxwell's but Lord Kelvin's
Yeah, that's true , and he did some of the same with thermodynamics. I guess there are very few that did something entirely original at the level of physics equations. Newton, Boltzmann, Heisenberg, Schroedinger, Lorenz. Who else, and how much did they use existing equations to work from?
well we can establish partial entanglements among an object and a planet.
to have absolude binary entanglement each particle must have the same period of spin duration and opposite spins, in partial entanglements we AVERAGE spining groups!
also the beholded from inside period of spin-duration - is a constant for all particles,
but in RELATIVISTIC groups, we only measure the BEHOLDED FROM EXTERNAL BEHOLDER-OR RANGE OF BEHOLDERS
PERIOD DURATION
statistically when a partial entanglement degrades when particles' period exceeds the mean semiperiod of the group, tend to form
new partial entanglements, witch as a group
still cancel the overall spin, but for dt time.
also statistically when spins disentangle
are supposed to fend off at random places,
but that is not the case if we have more particles at one side.
That's why we have gravitational attraction - acceleration.
It is more probable and a lower spin arragnement to cancel overall group spin
with a new patial entanglement group
than to generate spin grouping with virtual particles of the void.
That last one is the reason why
the void expands so fast.
In vast empty regions we called mistakenly dark energy groud, there is no option
for entanglements among particles
but among particles and virtual particles, even among
virtual/virtual particle bonds,
emtpy space is itself virtual particles,
that's why vast empty regions of space
expand,
and that's why we have the opposite effect,
of visrtual particle's death at the external part
of galaxies, that give the mistakenly said dark matter effect.
Virtual particles if they have option,
prefer to die and get transformed
as pure energy,
when virtual particles die at the outter edges
of a galaxy, they simply kill space, because that is what they are.
Energy is not lost, only transformed entropically in accordance to the third law of thermodynamics.
Even if a galaxy seems very ordered,
it maintains form via entropic transformations of energy, from more concentrated froms of energy like virtual particles, to acceleration, death of space, and some heat.
We have measured that effects.
That heat, also the fact tha Voyagers
were a bit closed than they should, simply because the Sun does not gnerate only gravity,
but also kills some space. Remember, space is virtual particles.
nice
Amen Apburner!
Unbelievably intelligent man. However, I can't believe we haven't used his ideas more yet.
Maxwells theory’s are the foundation of the modern world, from wireless technology to GPS. All lead back to Maxwell.
@@gavinross2471 even still.
I would just like to say that Maxwell started out by trying to understand the work of Michael Faraday who described electric and magnetic fields experimentally! As Newton said on the backs of giants!
By the way this is an invitation to see an artist theory of the physics of ‘time’ as a physical process!
I think Professor Flood had had a little too much Rhenish white before giving this giggly lecture. But, still, another great lecture from Professor Flood.
green isn't a primary color. You cant mix those in any combination to get yellow; cause yellow & blue make green. some would argue cyan and magenta; however, red, yellow and blue is technically adequate. My palette is {red, yellow, blue} with white and black for shading.
Proteus Augustus - Green is primary color of light, not a primary pigment. Mixing of pigments is not the same thing as mixing light.
argh, video won't load :-(
Superb lecture - but shouldn't the title be "James Clerk Maxwell: The Greatest Victorian Mathematical Physicist" (with no "s")
I do not like British politics,but respect there amazing minds!
Maxwell comes befor Einstein
His work is far more important than Einstein's in terms of applications. Far more.
There's no point comparing geniuses of that caliber.
+drstrangelove09 + Maxwell did provide a unified set of EM equations but it isn't as if he invented electricity. The existing equations from Faraday, Gauss and Ampers's work were almost complete already and certainly sufficient for developing electrical devices. But in any case, it is a sad day that we measure the greatness of a scientist in terms of practical application, rather than advance in understanding.
Giorgos Argyropoulos
I'm not really comparing "genius" per se. I'm compare utility and importance of application.
chrisofnottingham
He came up with the equations that are used today to design all manner of E/M devices.
You say "came up with" I say "unified". As an electronic engineer for twenty odd years, I have to say that I have never once used any of Maxwell's equations. In fact they weren't even taught on the engineering degrees because the equations from Faraday et al are already more than sufficient.
It's a college lecture for students of physics. Not for average Joes.

What is it that makes the mind of children find an interest in the invisible and silent laws of nature rather than the inaccurate relative behaviour of the social sciences and art and religions and man made laws, as we find in our courts ?
I feel that the great minds within a developing nation must slowly wait till the average human mind of its people sway away from finding solutions in religious and artistic explanations though these subjects I must admit seem to prepare the minds of men to think in another dimension in preparation for the move from a qualitative and emotional conception to a quantitative descriptions of reality as describe so neatly by Maxwell's equation. The Brilliant manner in which Maxwell described the Electromagnetic behaviour warrants him to have lived and buried amongst the best minds though I must say there were others who did not get the popularity that Maxwell enjoyed. Life was cruel to some of the best minds in this world as they hid their lights under the bushels, when living in this world does pay to seek some popularity through better publicity.
I am not sure that I saw Maxwell's name written at Canterbury Cathedral, for he was not buried there if I am not mistaken. Of his four equations I best admire the Curl of H = a conduction current plus a displacement current where this applied to the insulation of a capacitor explains all Radio Frequency transmission in the larger capacitor called the Universe!
He is resting at Westminster Abbey, between Sir Isaac Newton and Steven Hawking.
Proflood floats like butterfly, but man what a sting.
Ive come to believe that nothing is real on TH-cam
including your comment
Um, wrong lol.
The original post was correct. I am not sure you understand what he meant.
This is not a video response.
The thumbnail is a picture of Kelvin's.
Lennox Xonnel - It has been corrected.

+Barry White You can't be serious. Sir Isaac Newton hasn't changed the world? He only helped conceive Calculus with Leibniz (which is widely used in engineering, astronomy, quantum physics, just to name 3), elaborated and developed the laws of motion which govern our concept of classical physics and invented the telescope (the very same structure NASA uses centuries later). Einstein indirectly lead to the cold war, hiroshima, chernobyl (it is a grim way to refer to his achievement but it has shaped our Planet nonetheless), he also lead to our current understanding of quantum mechanics and is at the origin of the beautiful theory or relativity. Maxwell is an illustrious figure but your comment is a hilarious insult to genius. Ungrateful minds grind my gears and if I am to be great, I would never tolerate to be belittled like this. Pay respect young man.
hahaha i hope you are trolling
After reading this one, I have to conclude you are just a bell-end who can't be helped in the comments section. Get off the comments and come back when you know how to appreciate..... anything.
Flat earth, yes of course.
I'm sure you have great credentials to boast. Hey don't forget an impressive musical collection Mr White.
Good day sir.
Barry, you're a joke.
@Barry White Didn't anyone ever tell you that you never ever go full flatard
It is a shame that Maxwell's introduction of displacement current is not mentioned, without which there would be no radiation.
Srinivasvithal Mirmira - Did the sun not shine before Maxwell?
I don't know about all this math and other stuff, I just thank god he invented coffee!
Why doesn't the speaker mention ’Maxwell’s magic hammer’?
Don Fox “silver” hammer.
Prof. Flood,
With all respect, I submit your short list is at least 1 name shy, that of J. Willard Gibbs. Boltzmann is another possibility.
Both personality and "politics" contribute to Gibbs' lack of renown. The man was reclusive and he did his work at a time American science lacked panache.
Gibbs was in communication with his European peers. Had he lived but a few years more, a "conversation" with Einstein would have been possible. Speculate as you like about what that might have yielded.
Eli D.
But Richard Feynman, think differ...
Another phenomenonal brit that nobody knows about.
Roger didit - On the contrary, everyone who is seriously interested in science knows about Maxwell.
Reading Irishman. Is anyone awake?
Like Oscar Wilde? Yeah, sure dude.
This presentation was poor IMO. This professor just summarizes his work, but doesn't really understand it at a deep level. Just read Maxwell's wikipedia entry in 5-10 minutes and save yourself 50 minutes of viewing time.
This one of my favorite scientific lectures ever. You have plenty of inclusions of Maxwell's actual writing that wiki doesn't have.
fredocorleone - No, thank you.
Maxwell was more important than Einstein. Einstein even built his idea for Special relativity on taking Maxwell's equations as 'laws'.
Aye
minute 1:20 Charles Darwin and what he published is right there with Maxwell.
speach patterns are stressing to listen to...
A great Christian aswell.

Troll here: Einstein.
God don't PLAY DICE, yo.
he rolls bones.
You shouldn't spray perfume near the audience, some will be sensitive and become sick.
Professor Flood doesn't do his lessons in person. It's just his hologram :/
Is it a college requirement that speaker should speak to himself?
เพราะ square root กลับสามเหลี่ยมกลับหัวใช้ไม่เป็น
Feynman thought there will be history in 10,000 years.
How unimaginative.
Come now. Maxwell was certainly more important than Einstein.
What Einstein managed to do was bound to happen - a lot of people were working on the same theories at about the same time. If Einstein hadn't figured it out it wouldn't have been many years before somebody else did.
***** I know he used Lorentz transformations but he never went to any length trying to disguise that.
I'm not aware of anybody contesting the legitimacy of his discoveries though.
MAXWELL BASED HIS EQUATIONS ON GAUSS AND AMPERE'S AS WELL AS FARADAY'S WORK. THEY ALL HAD TO "STAND ON THE SHOULDERS FO GIANTS," AS DID EINSTEIN. BUT IN THE CASE OF EINSTEIN YOU HAD ALL THE GREATS LIKE PLANCK ,LORENTZ AND POINCARE WHO NOT ONLY MISSED THE MAIN POSTULATES OF RELATIVITY, BUT THEY GLADLY AND REALISTICALLY GAVE EINSTEIN FULL CREDIT, AS THEY WERE ALL UNABLE TO TAKE THE GIANT CREATIVE LEAPS. MORE IMPORTANTLY NONE OF THEM, NOT EVEN MAXWELL WERE ABLE TO PREDICT THE CONSEQUENCES OF EM OR RELATIVITY AS DID EINSTEIN: EINSTEIN RINGS,LASERS, ETC. EVEN HILBERT DID NOT INTUIT ANY OF GEN REL UNTIL HE STAYED AT EINSTEIN'S HOME AND SAW HIS INITIAL EQUATIONS.
RAY FRANCO In the future, if you wanna avoid looking like a moron - turn caps lock off.
retarded to say it would have happened at that time he was the only one in that time with his kind of thinking but true eventually some one could have came up with a similar theory
Sheldon Belcher No he wasn't - that's my entire point. Many physicists were working on the same problems. Go read some scientific history.

Turned it off after the first sentence .... "One of the most important mathematical physicists of all time, coming only after Newton and Einstein"
Way to go Professor Flood.....the unification of electric and magnetic fields, our understanding of light, it's speed and how such electromagnetic waves propagate....all down there in third place after an apple falling on the head.
What a bozo - even Einstein replied, no he was standing on the shoulders of Maxwell when asked if he was standing on the shoulders of Newton.
pathetic that you attribute an apple to newton and noting else, he stood on the shoulders of Maxwell because his field was the same and Maxwell was more recent.
Newton in Mechanic field, Maxwell and Einstein in electrical field. Contribute in their own unique ways. Keep you mind open....
Maxwell was also a lover of Jesus Christ as was Faraday.
So what?
He turned out to be dead, so both of them decided on women instead.
Appalling bumbling mumbling back and forth stumbling. Lip smacking toilet
Trying to be funny too often... Can't watch
Kharn Kaluza I agree the speaker should seperate himself appart from the great man he is discussing, James Clerk Maxwell.
One of the true greats.
