    Implicit differentiation? implicit integration?

    We have implicit differentiation: i.e. x^2 + y^2 = 7 -> 2x +2y(dy/dx) = 0. and solve for dy/dx gives you the derivative of y with respect to x However, is there not implicit integration? for terms linear in y, i.e. x^2 + y = 7 -> X^3/3 +int(y) = 7x + K, and solve for int(y) to...

    Gauss's and Coulomb's law forms and gravitational field

    The latter of maxwell's equations, which describe changes in flux that produce certain fields really unify E & B fields. Also, simple experiments on a macro level prove this. I wasn't aware that gravity can induce another field, or vice versa. Where the strong field is unity, EM is on the...

    Gauss's and Coulomb's law forms and gravitational field

    Thanks for the link to wiki (K.J H), that's quite useful. I was thinking more along the lines, that if E induces B, and vice versa, then it might be possible that the gravitational field induces another field also. In maxwells four equations (simplified), we have gauss, int(E.dA)=q/e and...

    Gauss's and Coulomb's law forms and gravitational field

    Consider int(E.dA)=q/e, guass law relating the electric field to the charge enclosed. One can also derive (using the more mathematical version of guass' law - involving the double integral) this same formuala for a graviational field. Here the permitivitty constant would be replaced by...

    Producing Water: Harnessing Solar Energy for Clean Water

    Take for instance (in a very simplistic way), a body of water on the Earth (i.e. a river, ocean, sea, lake ect.). The sun heats the body, causing the water to change from a liquid state into a gaseous state (i.e. evaporation). The water vapour rises to a certain altitude where it begins to...

    Can Tokamak Reactors Achieve Break-Even Fusion?

    I mentioned in a previous post that the JET fusion reactor, "the world's largest nuclear fusion research facility" http://www.jet.efda.org/" . According to http://www.engnetglobal.com/tips/convert.asp?catid=12", 1 MW-H is equivelant to 2.25*10^28 eV. It is diffucult to find the total...

    Can Tokamak Reactors Achieve Break-Even Fusion?

    Sort of - in a way. Perhaps the problem of the continual confinement of fusion - at least in the nature as proposed by the tokamak is an unrealistic expectation. The problem I see is that natural fusion reactors, as for instance the sun, are able to confine and sustain continual plasma...

    Can Tokamak Reactors Achieve Break-Even Fusion?

    I'm quite intriguided as to why exactly ITER has decided to use the tokamak design as the basis to "demonstrate the technical feasibility of fusion power", especially when it has several countries involved as partners, and a large amount of joint funding and time has been, and is to be, invested...

    Can Tokamak Reactors Achieve Break-Even Fusion?

    I think that they have already achieved fusion reactions inside the reactor - but for only a very short period of time. Obviously there has been no net gain of energy from the plasma (no breakeven, as far as I am aware) but they have nevertheless been able to obtain energy from fusion reactions...

    Can Tokamak Reactors Achieve Break-Even Fusion?

    Note: Perhaps only in the millions of amperes with the heating field, I am not sure about the confinement. But regardless, they use large amounts of electrical power.

    Can Tokamak Reactors Achieve Break-Even Fusion?

    According to the torodial tube, closed ended geometry of the tokamak, it appears as if the plasma is desired to be contained for a long period of time, giving low densities. This would then suggest that the large currents (in the millions of amperes) employed by both fields (torodial &...

    Can Tokamak Reactors Achieve Break-Even Fusion?

    I was thinking that if ITER has been underway for sometime, and that they have already poured a large amount of funding (financial), research and time into the project - that producing artificial fusion is a theoretical possibility. I am sure that they would have 'crunched the numbers' before...

    Can Tokamak Reactors Achieve Break-Even Fusion?

    I have tryed to look into ITER and tokamak reactors latest updated information online, and cannot find any real specifics on it's latest progress. Does anyone know of where we are with producing sustained fusion for energy purposes, through currently using the tokamak? Is it possible to...

    Why Does Double Slit Experiment Support Wave Nature of Light?

    How is there interference of wave trains (multiple) if only one photon passes through the gap at a time? Young's explanation of this phenomenon suggested multiple wave train's - i.e a coherent light source. These series of bright fringes appear on the screen as a light source is directed...

    Why Does Double Slit Experiment Support Wave Nature of Light?

    Young conducts the intial double slit experiment and observes the bright fringes on the background screen. His explanation for this phenomenon is that there is wave interference. However, obviously if the experiment is conducted again, this time with the intensity lowered so that only one photon...
