| Metric Tensor | Mandelbroth | I can't edit it, but this page bothers me. I think the whole thing should be a subcategory for a metric tensor entry or a separate page, like "Metric Tensor... |
| simple Lie algebra | lpetrich | What I describe is evident when one uses the "Cartan-Weyl basis": 10.Cartan-Weyl_basis.pdf (http://www.weizmann.ac.il/home/fnkirson/Alg13/10.Cartan-Weyl_basis.pdf) |
| magnetic field | boisebrats | it would seem that if this was so, that all other planets mars, mercury etc. would exhibit the same magnetic field with varying mathematical predictability,. . . |
| magnetic field | Velikovsky | Is it a possibility that the earth's magnetic field is a result of it's rotation within the electrical/plasmic field/flux given of by the sun? If the earth were to theoretically... |
| simple Lie algebra | amos carine | "The Cartan subalgebra can be used in a fashion analogous to the projected angular momentum in quantum mechanics, with the other elements being analogous to raising and lowering operators."
Is there... |
| electric field | Drmarshall | So electric fields, having energy, have inertia
So they "distort space" - whatever "space " is - and "cause gravitational forces (whatever they are). |
| magnetic field | SteveDave | Per Dr. J. Marvin Herndon in 2007, the Earth's elctromagnetic field is genrated by a possible fission reactor system at the Earth's core, enlayered by an unknow liquid system flowing... |

| Euler's formula | FPinget | Euler's equation eix = cosx + isinx is used to describe many physical events, among them the phase relationship between current and voltage in simple AC Resistor-Inductor-Capacitor type of... |
| electric units | tiny-tim | Added energy density, and http://www.qsl.net/g4cnn/units/units.htm |
| moment of inertia | Qasim Balti | Best Example of Inertia:
A Bus moving and there are some people who are sitting in it but suddenly when Bus apply brakes the people who are sitting feel some kind... |
| Euler's formula | tiny-tim | Corrected mistake in LaTeX. |
| angular momentum | tiny-tim | Corrected references to centre of rotation in "Calculating dL/dt:" in ext expl. Thanks to Karol :smile: for pointing this out! |
| momentum | Govind.A.S | Section 3 and 5 OK now. Question 2- not answered
2) I section6, p=h/wavelength, is this momentum a vector? If so, what is the direction? If not, why not?
~EDIT (tiny-tim): p=... |
| Lorentz transformation | Padam R B | Why do we take velocity as constant while deriving lorentz equations and not constant while deriving energy mass equivalence?
~EDIT(tiny-tim): a Lorentz transformation is defined as between two inertial observers (ie... |
| work done | Govind.A.S | Why do you say "Potential energy depends only on position,"?. What about "configuration"? or elastic potential energy of a spring? Microscopically, it depends on positin of atoms, but when we... |
| momentum | Govind.A.S | 1) In section3 and 5, p, delta(p), J etc are vectors. Pls show arrow symbol on top.
2) I section6, p=h/wavelength, is this momentum a vector? If so, what is the... |
| wave-particle duality | slayerwulfe | particle or wave to me is not an argument to be solved,language is/maybe a liability here as we all perceive language differently. is it possible for a particle to be... |
| wave-particle duality | WMJ | A reaction force? The crux of the matter is, what sort of force is it. The force must be influenced by the two slits, in which case it could be... |
| quantum angular momentum | lpetrich | Here's what happens. Use the same direction for states of L, S, and J. The orbit states |ml> and the spin states |ms> combine to make a state |ml,ms>. The... |
