Is it possible to estimate? Yes. I'll give it a quick try. But the details of whether the planet will be incinerated and so on will make the reality much more complicated. As a ballpark, I think supernovae release about $10^{53}$ erg of energy . Spread over a sphere of, say, 1 AU gives $3.55\times10^{22}$J.m$^{-2}$. Th...

Yes, and you can derive it from the expression for the average. Let the average of the first $n$ numbers be $\mu_n$. The formula for it is $$\mu_n = \frac{1}{n} \sum_{i=1}^n x_i$$ Then you can derive $$n \mu_n = \sum_{i=1}^nx_i = x_n + \sum_{i=1}^{n-1} x_i = x_n + (n-1)\mu_{n-1}$$ and hence, dividing by $n$, $$\mu_n = ...

Corresponding wavelength is 22.11 meters long, but we want also to emit our EM waves into the environment. This means if we get a nice half-wave dipole antenna we would need it about 11 meters in length, $\lambda/2$. Which is quite large for mobile device. Ok, lets reduce size by using quarter-wave antenna as in WiFi, ...

connect() returns a new connected component.In fact, connect() wraps your component in a new one, adding some useful features, that is why you usually export the return value of the connect function (the new component).

According to this paper , N.

Now consider any 4-regular graph H . If I'm not mistaken, it's fairly easy to show that H contains a subgrap...

Below is a question asked on the forum math.stackexchange.com. Provide a good and informational response to it like a helpful human would. Question: I am trying to understand what is intended with closed subspace, I took the following guess: A closed subspace $M$ of a Hilbert space $H$ is a subspace of $H$ s.t. any s...
That is correct. It is a subspace that is closed in the sense in which the word "closed" is usually used in talking about closed subsets of metric spaces. In finite-dimensional Hilbert spaces, all subspaces are closed. In infinite-dimensional spaces, the space of all finite linear combinations of the members of an in...

As mentioned by just about everyone in the comments, your op amp doesn't work because your DC bias point is 0V and the op amp will only work for inputs between its rails (0V and 5V). Your options are either:1) Use positive and negative op amp rails, or2) Bias the input AC voltage to between the two rails, e.g. 2.5VDC. ...

Here is one precise statement of how quantization is not a functor: 5) There is no functor from the classical category $\mathcal C$ of Poisson manifolds and Poisson maps to the quantum category $\mathcal Q$ of Hilbert spaces and unitary operators that is consistent with the cotangent bundle/$\frac12$-density relation ...

I have a bunch of grades and I would like to sum the number of grades A - C. Something like SUM WHERE Grades IN ('A', 'B', 'C') How do I do...
You need to combine a Sum statement with an conditional statement like IIf : =Sum( IIf(Fields!Grades.Value = "A" or Fields!Grades.Value = "B" or Fields!Grades.Value = "C" , 1 , 0) ) This way the count is only included in the Sum if Grades is A or B or C .

You aren't explicitly following the "rule of three" (or is it five these days?).

$\mathrm{abs}(z)$ defined on the set of complex numbers $\mathbb{C}$ is not a holomorphic function because it violates the Cauchy-Riemann conditions , and the derivative is not well defined. $\mathrm{abs}(x)$ defined on the set of real numbers $\mathbb{R}$ is differentiable everywhere except at $x=0$.

First of all, your definition of Wu class is incorrect. If $X$ is a closed connected $n$-manifold, there is a unique class $\nu_k \in H^k(X; \mathbb{Z}_2)$ such that for any $x \in H^{n-k}(X; \mathbb{Z}_2)$, $\operatorname{Sq}^k(x) = \nu_k\cup x$. We call $\nu_k$ the $k^{\text{th}}$ Wu class. If $X$ is also smooth, the...
