Learn how to use wikipedia:

http://en.wikipedia.org/wiki/Maxwell%27s_equations

"Maxwell's equations are named after the Scottish physicist and mathematician James Clerk Maxwell, since in an early form they are all found in a four-part paper, "On Physical Lines of Force", which he published between 1861 and 1862."

yes I know that. then why are they named after other people?

>>4930534
They are each names after there respected authors.

Do your own fucking homework.

\thread

cos math is fucking stupid and you're stupid for doing it.

>>4930546
WELL IF THE'RE NAMED AFTER THEIR RESPECTIVE AUTHORS, WHAT THE FUCK DOES MAXWELL HAVE TO DO WITH THEM?!

>>4930550
He put them together cockpotato. It's like not calling a dictionary a dictionary just because a whole bunch of people came up with those stupid words.

>>4930553
So really Maxwell did fuck all?

A dictionary takes a bit of time to put together, there are a fair few words. On the other hand, there are only 4 laws here.

I'm gonna do it myself: brick, breeze-block, marble, granite.
There are 4 related words for you, grouped neatly. these shall now be known as "Anon's Words of Stone Related Hokey-pokery".

>>4930559
Congratulations you are now a mathematician. Here is your 300k starting.

>>4930559
He organized them, and formalized a lot of the math.
This was enough for them to be known as "maxwells laws".
Simple as that.

Stop asking fucking retarded ass questions.

Well then they shouldn't be called Gauss's, Faraday's and Ampere's...

>>4930580
Do you even know what a troll is? there was no wit in that post...

>>4930559
gauss law is a mathematical theorem
maxwell made corrections to one or two of the laws
he put them together to get the wave equation

>>4930575
there were a bunch of laws called Gauss's, Faraday's and Ampere's laws which seemed to be unrelated. maxwell came and saw its actually one big law, he rewrote the 4 laws in a new form and combined it into 1 law. so the combined law is Maxwells, but the individual laws are the other peoples.

>>4930608
Thanks. That was a actually a helpful answer. Rather than these other /sci/ residents who leap down your throat and call every question asked stupid.

Just become a tripfag already, so I can properly filter out your posts.

No respect for this guy here.
"In 1884 he recast Maxwell's mathematical analysis from its original cumbersome form (they had already been recast as quaternions) to its modern vector terminology, thereby reducing twelve of the original twenty equations in twenty unknowns down to the four differential equations in two unknowns we now know as Maxwell's equations. The four re-formulated Maxwell's equations describe the nature of static and moving electric charges and magnetic dipoles, and the relationship between the two, namely electromagnetic induction."

Maxwell gets too much credit.

>>4930626
he didnt do anything new, so it remains Maxwels law, thats why they call it the Heaviside formulation of Maxwells law.

>>4930632
>didn't do anything new
>20 equations and 20 unknown variables down to 4 diff equations and 2 unknowns
>basically took something no one would understand to something a college undergrad can learn
Wow, you're retarded

>>4930639
do you even know what the original 20 equations were?
Heaviside wrote it in 8 equations with 8 unknowns, combining then into 2 vectors and 2 scalars (instead of 2 quaternions)
the rest of it he pushed aside becasue it didn't fit into this 4 equations, like ohms law, the Lorens force and the gauge transformations.
he didn't reduce any unknowns or equations, he just rewrote them from quaternions to vectors, then divided them into the Maxwell equations and 4 auxiliary equations.

>>4930650
Yes, he simplified them. You're implying he didn't do anything while someone had to read Maxwell's original papers and understand them to do that.

>>4930657
yes, he didnt do anything new.

>>4930659
Did the revisions of Maxwell's Publishing exist before they were revised? No. Therefore Heaviside took them and simplified them. You're saying that since Heaviside didn't invent vector analysis, he did nothing new.

>>4930664
he made no new law, but you want a law to be named after him? how does that work?

>>4930520
Heaviside equations

>added nothing new

maxwell added displacement current you fucktards.

Come now OP, you posted the equations in their first year undergraduate form.

You should have just spent the year learning about how he unified the different theories of electicity and magnetism gloriously into 4 simple equations shown there, and then showed that light was a manifestation of waves in electric and magnetic fields.

What have you been smoking all year?

>>4930944

Correction, not those 4 precisely, but something equivalent.
