# Newton and Coulomb laws link

## Main Question or Discussion Point

Do you know if someone already found a link between Newton : F = G mm'/r^2 and Coulomb : F = K qq'/r^2 laws ?

Are you asking if there is a theory of unification of electromagnetism and gravity?

The mathematical link is trivial, it is simple potential theory and differential equations.

of course the mathematical link is trivial but I was thinking about the unification between electromagnetism and gravity. I know it is the famous GUT that everybody wait. But I wanted to know if a great expert like you has original informations out of string theory.

no GUT is strong + electro + weak.

If you want to acquire information about string theory, we have a sub forum called "Beyond the standard model" where people are more than happy to answer your questions and put you in the right direction.

However, I encourage you to search for older threads and reading FAQ and sticky threads and the forum rules before proceeding.

you have not respond to my question, I said "out" of string theory !

I can't understand everything you are posting here since your English is not "the best".

"original informations out of string theory"

Means what?? The grammar in that sentence is also wrong, sorry, but it is really hard to know what you mean.

ok glenn I will try : I mean : do you know something different from string theory and able to make a physical (not mathematical) link between these laws.

"something different from string theory"

do you mean

"something different THAN string theory"?

Also, the physical link will involve math of course...

true, different than string theory and with all the math you want :-)

why not string theory?

why not ?

Yes, why don't you consider String Theory as a possible TOE?

I consider string theory a possible way but perhaps it is not the only way and my question is do you know another way ?
