    Undergrad Why ##a^0=1##?

    ##a^0## can't be ##0## because if ##a^0=a\cdot 0 =0## for every ##a##, then ##0^0=0##, that is not true in mathematics ... In addiction ##a^0=a^{0+0}=a^0\cdot a^0##, now ##a^0=\left(a^0\right)^2## that is only if ##a^0=1## or ##a^0=0##. By the nosense of ##a^0=0## follow that ##a^0=1##. Ssnow

    High School Example of a model for a function

    Thank you @renormalize ! This is a nice transformation!! It is connected with the entropy and the information theory ... It is a good example ... :smile: Ssnow

    Observing the form of the graph the clearly association is an event that change very fast in a short time, like an explosion ... I don't know probably in chemistry ... Ssnow

    High School Example of a model for a function

    Hi!! There is some natural phenomena (finalcial or other field ... ) that is modelled by the following real function (of a similar function less then a constant): $$y=f(x)=x^{\frac{2}{x}}$$ or $$y=x^{\frac{k}{x}}, \ \ \ \ \ \ \ \ \forall k\in\mathbb{R}$$ thanks, Ssnow

    How close are we to getting micro reactors?

    Hi Josiah, I think we are very close, U.S. there is Radiant that has projected micro-reactors for small community or industries. There are avanced project for micro-reactors of 1 MWe, with expansion until 1 GWe. PS. See https://www.radiantnuclear.com/ Ssnow

    Undergrad Deriving the conformal Laplacian

    Hi to all!! I have a problem to derive the conformal laplacian \sum_{m,n}g^{mn}(y)\partial_{q^m}\partial_{q^n}(\psi|\det{(g)}|^{1/4})(y)=\sum_{m,n}|det{g}|^{1/4}(\Delta \Psi -\frac{1}{6}R(y)\psi(y)) where $$g$$ is the metric associated to a Levi Civita connection in a normal frame, we have...

    Undergrad Partial derivative of Dirac delta of a composite argument

    Hi, I think there is an error in the last term, this must be zero because you must be able to reconstruct the conservation condition ... Ssnow

    Integral of e^cosx: Answers Sought

    I think you can try to have a infinite sum expanding by Taylor the exponential: ## \int e^{\cos(x)}dx=\int 1+\cos{x}+\frac{\cos^2{x}}{2!}+\frac{\cos^3{x}}{3!} dx ## now by linearity: ## \int e^{\cos(x)}dx=x+\sin{x}+\int\frac{\cos^2{x}}{2!} dx+\int \frac{\cos^3{x}}{3!} dx + ...## If you have...

    High School Notation for infinite iteration

    Hi Physics Forum, I want to ask if there is an "appropriate" notation for the infinite self-iteraction of an analytic function ##f(x)##, that is ##f(f(f(...)))##. For example I know ##f^{(+\infty)}(x)## can be a way, but there is an operator notation as for the infinite sum...

    Engineering Calculating maximum flux density

    Hi, yes I think the substitution can be of the following form ## \alpha \,=\, \frac{50}{\pi}t## do the differential will be ##d\alpha\,=\,\frac{50}{\pi}dt## and inverting ##dt\,=\, \frac{\pi}{50} d\alpha##, now put it into your integral ... 😄 Ssnow
