 0:57 sonya xD

[Kuwaiti1990]

Sonia is man!!!!!!

[myrtlebox]

Here is a summary of what Maxwells equations MEAN relative to the summary at 1:00

1. The Electric flux is proportional to the enclosed charge

2. A changing Electric field induces a changing Magnetic field

3. Magnetic monopoles DO NOT EXIST

4. A changing Magnetic field induces a changing Electric field.

2&4 produce the speed of light as a function of (permeability and permittivity)

[TheSyrupMan]

Very informative.

[ramiro48]

HAHAHA!

[0tecnica00of00skate0]

W T F ???

[FragZz]

awesome!

[xenoepist]

Sonia's got facial hair :S

[vertexgo]

just interpretations of the fundamental theorem of calculus - which is the equation for everything.

[lustatus]

Where is Nicola Tesla's picture ?...he is the one who discovered that this formulas can be used to get free energy from a vacumm space.

[qed100]

@lustatus He never did any such thing.

[andyelgrand0]

sonja... grew a beard, the years have not been kind to her.

[hobosyan]

If you can understand all these equations in that speed you show you are great!:) I really wanted to learn something but only saw some great scientists under mortal combat:)

[VERGIS92]

Ha, I actually have this book, I love electrodynamics, from a practical standpoint it is absolutely necessary in the design and development of new and better RF antennas, and this requires knowledge of EM right down at atom level. QED is the determining factor in the success of several other inventions that could change the world

[69erthx1138]

@VERGIS92 Griffith's 3rd ed.Great book! Funny you mention quantum electrodynamics, I don't find too many reader-friendly books on technological applications for this subject. At the research level the literature is ultra specialized. As photonics moves in on electronics, I think at the integration level a knowledge of QED will be fortuitous for anyone investigated this area.

[difuso2204]

seeeeeeeeee!!

[blindcutter]

some people are trying to learn, stupid !

what a douch !

[HorizonDelta]

It's a good video ! More tech in "Wonderful electric energy-Tesla wireless" by HorizonDelta

[tparker37]

I'm heart the Dirac delta function

must be TEKKEN 3  (tournament of warriors)

[chillman442]

how lame is this that I am watching this shit on a friday night

[Jillageyelash]

ugh.im so sick of that book.

[seniorbooboojuice1]

Haha that was awesome

[lllLaquetepariolll]

I laughted my ass off XD

[idiosynkrass]

:D that's the stuff.

[Midvinterblot542]

I should be doing my Griffiths homework instead of watching this video. Good job btw!

[obogz]

:))))))) funny shit right hereee :)) haaa

[BeingOfLight111]

thats awesome

[Kuwaiti1990]

LMAO at the names introduction

[albeilmate]

absolutely fantastic idea

[vanderbilt887]

I've been butchering thru multiple Griffiths' books as well, this is really a nice refreshing wind :-) Thanks.

[LeconsdAnalyse]

1. curlE=-9H/9t (Faraday`s Law),2.curlH=j + 9E/9t (Ampere-Maxwell law),3.DivE=q (Coulomb`s law),4.DivH=0 (Gauss`s law). q=charge density,j=electric current. If q=j=o, both E and H satisfy the homogeneous wave equation. 1.&2. are evolution equations, and 3.&4. are constraints.

[DenShagiah]

I not speac English

[physicist21]

This is awesome... Is really good

[Plutoniummatt]

lol nice delta function

[detibry]

haha i've got a test tomorrow on the electrodynamics portion of this book! why am i on youtube!

[dansharkhunter]

::Great video!

The equations are beautiful and fascinating.

The song adds to the tingle.

From Mortal Combat.

Funny cause in some ways there is resemblances...

[TheVladimirtk]

still the best music in the world =) thanks for the equasions i passed the ones i havent passed and understood alot out off them thanks.=)

[cpinnago]

damn 0.03 is my text book for electrodynamics class....lol nice... !! way to go Griffiths

[Channypogosticks]

song?

[69erthx1138]

Although I have great respect for David Griffiths professionally, his book is very overrated. Your video is very nice, like how the Delta function squeeks in at :25

[xixzxzxyx]

Griffiths is not my favorite, but it is decent. If you plan to be a physicist, books like Greiner or Schwartz are much better.

[KakHazhar]

lol

[rocco133]

that's the music maxwell heard every day

[natere2]

griffiths! NOOOOOOOO!!! LOL man ahven't seen that since undergrad!

[Cymator]

Epic WIN

[josephboog]

Thats great! Hell yeah. Good break from studying. Thanks.

[Ritzoid]

Epic.

[gvsfgdf]

haha i love the mortal combat song and how badass it makes the physicists look...... :D

[jimmyshitbags]

hahaha this is possibly the best video on the tube

[13nick27]

x-D lol GOLD!!

[poloacho]

jajaja freaky!!

[BarriosGroupie]

not many female viewers here then

[quadricode]

Hahahaha, Sonya.

[TheDireAvenger]

Now do that with a logical progression that goes into Quantum Electrodynamics from Maxwell's Equations and I will be impressed XD

[Troinik]

Haaaa lorentz-sonya

[mijnagendaismooi]

Wouw, is this real?

[UrRedeemer]

im a physics student in holland, and i have this book and i just wanted to say:

HAHAHAH that was funny XD the video just throws equations at you with exciting music.....well no need to read the book now...

[jaafar42]

creative .

[995715202]

if any of you have taken a course using this text, it is mortal kombat. it is used as a prelim to jackson's classical electrodynamics..need I say more.

[995715202]

subzero? LOL I love this

[995715202]

Thanks, I needed a good laugh. laughed so hard I thought my ribcage was going to explode!

[BarriosGroupie]

Griffith's text is a doddle whereas jackson's is... on another level altogether

[bdiz86]

Agreed. Being in grad school now, Griffiths has become a favourite of mine to translate Jackson's.

[1czelaya]

Jackson's book is horrifically difficult. It was the first book where I literally got lost in the math (even with two semesters of mathematical physics, real analysis, and complex analysis). I could study that book for a decade before I got comfortable with it. The homework problems are just plain impossible at times. You must have a good understanding in Electrodynamics before tackling Jackson's book. But I'm sure you know that by now all to well.

[69erthx1138]

@1czelaya yea, Jackson is tough, but getting through it makes feel just a tad taller!

[valitzu]

lol, is that really Sonya?

[Thymonico]

Hahaha! Genius! :D

I learned a lot from this video, thanks! ;P

[ogirv101]

if it wasn't for Maxwell, we wouldn't be watching this in the internet............

[AndrewRiot]

exp^5/5

[ForceDestroyer]

LOL EPIC 5/5

And Mortal Combat indded guys! (Can't be anything but Griffiths for the first frame, huh? :P )

[eazylee369]

I've just realised that I'm a geek - I thought that was great!!

[Cdamann]

what is the music? sweet vid BTW

[Hawk3766]

THIS WAS GREAT!!!!!!!!! HAHAHAHA......have not laughed this hard, or this much, in MONTHS!!! Thanks for making and posting it!! Good sense of humor, and thanks for helping me to get rid of some flusteration. I Needed The Break!!.....

[Matrix29bear]

Is this an introduction or a math slide show?

[bdiz86]

Neither. It was me getting frustrated at my E&M homework one night and finding a way to vent. I think it came out rather well, other than the one error that is documented somewhere in the comments.

[anonimoculto]

@Matrix29bear Neither of them. This is a complete course in 1:12 minutes; this is what I would call thunder course (rsrsrs)... Perhaps the book is very good on graduation level. I've studied on it.

[Kunzahe]

EPIC

[hamsterpoop]

hahaha what the fuck did i just see?

[johgall]

This video is great! Will there be a cgs (preferably esu) version because i hate SI

[bdiz86]

Bah, I'm hating cgs units for my Nuke & Particle class. I keep converting back to SI units, its just natural for me.

But if you want, just take the 1/ (4*pi*epsilon_0) to be equal to 1 and go from there.

[69erthx1138]

@bdiz86 I really don't know why students get so mixed up when it comes to Gaussian and CGS. The 1/4pi counts the theoretical volume of the origin of a so-called Gaussian surface shrunk to an infinitesimal size. In any other system, that unit is dimensionless. I still find it strange how this can approach a finite number, but the integral over a delta function is one, so go figure!

[EnDieG]

best soundtrack evar ^^ but i hate maths and physiks ^^ the end is cool with the persons :P

[neil1337]

This video was disappointing because I wanted it to explain the equations.

[Liaoxiornis]

lol yeah. I thought I was going to get a good science vid . . .

[AqualinespiritPL]

Yeap - same here.

[DonCorleoneQ8]

WOW !!!!

Love it !!!!!

[TheBestAboveTheRest]

Ya know, i learned nothing, but it was still cool

[lolhun1988]

LOooooooooooooooooooool :D FAVORITE!!!!!

[eldominicanboy]

nice, I'm adding this to my favorites

[BrodyPianist]

erm

lol

griffith for the win

[kanepart2]

this is the end of all my Electromagnetic woes

a2+b2=c2

[MajorUtah]

damnnn-iitt!!  Nice job.... *XD

[00TrissMerigold00]

Sorry, I meant "test" =)

[00TrissMerigold00]

I have an oral text about Maxwell's equations tomorrow. I don't know whether to laugh or cry watching this video =)

[thoughtheglass]

adding to favorite to watch every day before exams!

[Max11551]

HAHAHAHAHAHA

Sweet!!!

[StudFI]

HAHAHAHAA, Best video ever!

[ycalm]

HAHAHAHAHAHAHAHA

job well done

[teslaandlyne]

Formulas ending in zero mean there is no source. For the mag field B, del B = 0 because its an endless loop and goes back on itself. Its a closed circle. The might be many such things in the air or ether.

[bdiz86]

Wasn't it that if del*B != zero, then it would explain magnetic monopoles, if they did exist. Actually, Maxwell's equations beg for magnetic monopoles, but we currently "know" that they do not exist.

[dramorez]

How do we know? It might be we simply haven't discovered them yet. Our particle accelerators might simply not be up to the task of creating magnetic monopoles. Anyways, cool film! I'm actually studying this book(Griffiths) right now and have an exam of it on monday. I'll probably be thinking of the mortal combat song the whole exam now ;).

[teslaandlyne]

curl B = J means the mag field encircles the current J, a tube along the exterior of a wire carrying current lets say. curl E = -dB/dt is AC to start with and has E, which is a straight vector, anchored in a circular path. Quickly going back and forth tangent on a ring path. If B is radial, as in Tesla's vortex coil, the path is more evident.

[oztronix]

Lots of your formulas ending with "=0"

Don't think so, what book you WRONGLY have this taken from ?...

[bdiz86]

Dude, only two of them are wrong, and its the same mistake because I used the same picture twice. Its at 0:22 and 1:05 for del x E = 0. It should be del x E = - partial(B) / partial(t). (Although technically for the case of a static magnetic field (B = 0), this is true). As for the others, I just checked again in Griffiths to make sure, and yeah, they are all correct.

[bdiz86]

In the case of Surface Integral of B * dA = 0, again, it is true that along a line, aka, Line integral of B * dl != 0, as it is mu_0 * I_encl, but for a closed surface, it is zero, as the field lines all cancel out (makes E&M much easier when stuff cancels out like that, especially when doing Gauge Transformations on it) If you look at 0:21 to 0:22, you can see how I have made this distinction.

[bdiz86]

Case: del * B = 0. In order to create a magnetic field, you either need a changing electric field (Faraday's Law), or you need an electron to move somewhere (Ampere's Law). If you draw out the diagram of a source point and draw divergence lines around it, you can see where the electric field is created. But those field lines aren't changing direction, they are constantly going in a single radial direction. Hence, no magnetic field.

[RainbowWerewolf]

Your curl of E at 22 seconds is wrong.

It should be -dB/dt

[bdiz86]

Yeah, thanks for pointing it out. I'm not sure if I even have the file anymore to re-make it. Another erratum to Griffiths?

[jmm1233]

mathematic Kombat

[herzogsbuick]

was that faraday as johnny cage? I for one hope so

[akashchokshi]

lmao... amazingg

[frostwow]

very fine vid, 5 stars :)

[pterodactyl7]

Never heard of Maxwell's Equations described this way!

[frostwow]

very entertaining , well done

[darrell14]

Electrodynamics tests are a mortal kombat v_v

[jmc8197]

I was hoping to watch a bald dude with a beard giving a lecture on these equations

[dsalpha18]

Lol, wtf, this is freaking awsome

[aljinu]

UQE ÑOÑO..................

[Grendelmonster8u]

I love it. You probably noticed that there's a little skip in the music halfway through - if you did it over without the skip it would be perfect. I gave it 5 stars anyway. Thanks for putting that together.

[galaxycoff]

Very funny, just FYI you made a typo in the title of your video "Electrodynamics" :D I LOVE it, and I totally forgot to tell you, I showed it to the lounge the other day and everyone LOVED it too :P

[phillipkp]

HAHAHAHAHAHAHAHA

[pahilario]

Will there be a Scrhoedinger's equation counter part?

[bdiz86]

Maybe, once I take Senior Quantum next year (assuming I survive E&M). I'm thinking Schrodinger's wave equations for the various electron states to the tune of the Imperial Death March?

[pahilario]

OK. Good luck! Keep up the good work!
