# What is Em theory: Definition and 15 Discussions

Texas hold 'em (also known as Texas holdem, hold 'em, and holdem) is one of the most popular variants of the card game of poker. Two cards, known as hole cards, are dealt face down to each player, and then five community cards are dealt face up in three stages. The stages consist of a series of three cards ("the flop"), later an additional single card ("the turn" or "fourth street"), and a final card ("the river" or "fifth street"). Each player seeks the best five card poker hand from any combination of the seven cards; the five community cards and their two hole cards. Players have betting options to check, call, raise, or fold. Rounds of betting take place before the flop is dealt and after each subsequent deal. The player who has the best hand and has not folded by the end of all betting rounds wins all of the money bet for the hand, known as the pot. In certain situations, a "split-pot" or "tie" can occur when two players have hands of equivalent value. This is also called a "chop-pot".
Texas hold 'em is the H game featured in HORSE and in HOSE.

1. ### Discover the Real Gem: Neoclassical Theory of Electromagnetic Interactions

TL;DR Summary: Book: Neoclassical Theory of Electromagnetic Interactions - A Single Theory for Macroscopic and Microscopic Scales I've found the book of Babin & Figotin: Neoclassical Theory of Electromagnetic Interactions - A Single Theory for Macroscopic and Microscopic Scales. I like their...
2. ### I EM equations - am I missing something?

Summary:: There seems to be a mismatch, in the "Maxwell's" equations, between the number of equations and number of variables. I was trying to play around with the equations for Electromagnetism and noticed something unusual. When expanded, there are 8 equations, 6 unknown variables, and 4...
3. ### I Does a conductor E field include a tangential component?

Background: an ordinary wire supports an external radial electric field proportional to voltage, and an internal axial field equal to current times resistance per unit length. The present question is whether the internal axial field has an external counterpart. The original question that...
4. ### B Maxwell's EM Theory vs Principle of Relativity

What was the problem between Maxwell's EM theory and the principle of relativity? Why went the theory against the principle? I understand that the EM theory says that Light was a wave and ether is it's medium. On the other hand the principle of relativity says that there is no state of...
5. ### I Can one get E=mc^2 using classical EM theory?

I'm wondering if one can arrive at E=mc^2 using only the physics of the late 19th century, in the following way: As light waves pass over an electrically charged particle, they push it in the direction of the wave motion, transferring both (kinetic) energy and momentum to the particle. Let's...
6. ### Explaining transverse theory of light using EM theory

just below eqn 3.25, it is said: At any given time, Ex is constant for all values of x, but of course, this possibility cannot therefore correspond to a traveling wave advancing in the positive x-direction. Why can't Ex be a constant?
7. ### Allowed EM Waveforms: Which Ones?

Homework Statement which of the following proposed space-time dependent electric fields in vacuum is/are allowed by the equations of EM theory? a) $$E_x=E_1\sin(kz-wt),E_y=E_2\sin(kz-wt),E_z=0$$ b) $$E_x=E_1\sin(kz-wt),E_y=2E_1\cos(kz-wt),E_z=0$$ c)...
8. ### Energy per unit length of a cylindrical shell of charge

Homework Statement "An infnitely long hollow cylinder of radius ##a## has surface charge density ##σ_a##. It is surrounded by a coaxial hollow cylinder of radius ##b## with charge density ##σ_b##. The charge densities are such that the total confguration is electrically neutral. Using whatever...

Hello, Am starting to read Electromagnetic Theory. Can you suggest some good textbooks on the topic that will help clear the concepts. Thanks in advance
10. ### EM Theory: Refractive index of water

Homework Statement Problem: Sea water has k = 80 in the low frequency limit. Yet its refractive index is around 1.34. Explain the discrepancy Homework Equations For a non magnetic dielectric medium, the absolute refractive index in the low frequency range, is given by : n = √k...
11. ### Can maxwell's EM theory explain the photoelectric effect?

i know that einstein explained it in terms of particles but can maxwells EM waves explain the photoelectric effect aswell?
12. ### Is EM theory in curved spacetime the same as unification ?

Is EM theory in curved spacetime the same as "unification"? I am wanting to learn about classical EM theory in curved spacetime (just curious) and I found this old thread containing some references https://www.physicsforums.com/showthread.php?t=3950 Is simply talking about the EM field in...
13. ### Delta function representation from EM theory

Claim: \nabla \cdot \frac{\hat{e}_r}{r^2}=4\pi\delta^3(\vec{x}) Anyone know of a proof of this? (or a reference which covers it?) We need to show that \frac{1}{4\pi}\int_0^R{(\nabla \cdot \frac{\hat{e}_r}{r^2})f(r)dr=f(0). The claimed identity can be seen in the solution for...
14. ### Studying Study EM Theory: No Classical Mechanics Required

Studying EM Theory?? Hi All, Is it possible to study Electromagnetic theory without knowing the concepts of classical mechanics. I have studied Newtonian mechanics but does not have any idea about Lagrange and Hamiltonian mechanics. I am concentrating on the below topics in...
15. ### EM theory and therom dynamic books

Hello, I need to purchase two books, for EM theory and Thermodynamics. I have briefly used couple of books years back and I can't seem to remember their titles or author. I slightly remember that the EM book was a blue color with a lots of information for first year - 4th year...
