The basic algorithm, which is due to Carlson (1979) and Carlson (1988), is to reduce the arguments recursively towards their mean by the rule:

For sufficiently large,

and the function may be approximated adequately by a fifth order power series

where The truncation error in this expansion is bounded by and the recursive process is terminated when this quantity is negligible compared with the machine precision.

The function may fail either because it has been called with arguments outside the domain of definition, or with arguments so extreme that there is an unavoidable danger of setting underflow or overflow.

Note: , so there exists a region of extreme arguments for which the function value is not representable.

Math Help - Minimum value problem

1. Minimum value problem

If y=2x-8, what is the minimum value of the product xy?

i only know how to get the max, i know you need to find the dirivative but i dont know how to make it the minimum.

2. Originally Posted by gebbal

i only know how to get the max, i know you need to find the dirivative but i dont know how to make it the minimum.
So you have

$A = x (2x - 8)$

A will have a max. (i.e. the derivative = 0). For a minimum, you need to check the endpoints. I used A as it might be an area and so $[0,4]$ and check $x = 0,\;\;\;x=4$.

3. im still confused. is the answer 0? since thats one of the end points.

4. Originally Posted by gebbal

Let us ask, where did this problem arise?

5. The problem is to minimize $A= 2(x^2- 4x)$. You don't need to differentiate at all. Completing the square, [tex]A= 2(x^2- 4x+ 4- 4)= 2(x^2- 4x+ 4)- 8= 2(x-2)^2- 8[/itex]. That is a parabola opening upwards so its minimum value is at the vertex, (2, -8).

If you must differentiate, A'= 4x- 8= 0 so x= 2. gebbal, you seem to be under the impression that the derivative is 0 only at a maximum. A derivative is 0 at a maximum, minimum or "saddle" point (the derivative of $x^3$, $3x^2$ is 0 at x= 0 which is neither a maximum nor a minimum). After finding where the derivative is 0 (a "critical point"), you still need to determine whether a maximum or minimum or saddle point. You can do that by checking the first derivative around the point. Here, A'= 4(x-2). If x< 2, that is negative and if x> 2, that is positive. That is, A is decreasing for x< 2 and then increases: x= 2 gives a minimum.

Or you can check the second derivative: A"= 4> 0. Since A" is positive, A' is increasing: it goes from negative to positive so, as before, x= 2 gives a minimum. Oh, and that minimum value is, as we saw by completing the square, A(2)= 2(2(2)- 8)= 2(-4)= -8.

# O'Neil's problem 2.10 on Tensor Derivations. Literature on the subject.

I am having real trouble trying to understand a problem in O'Neil's "Semi-Riemannian Geometry" and I can't find much literature on the subject. I will expose the problem and I will be grateful to accept hints, solutions and bibliographic sources on tensor derivations.

Problem 2.10 (p.53) Prove that a tensor derivation $\mathfrak{D}$ has $\mathfrak{D}_0 ^0 = 0$ if and only if $\mathfrak{D}_0^1$ is $\mathfrak{F}(M)$- linear (here, $\mathfrak{F}(M)$ stands for all smooth real-valued functions on $M$). Then by interpretation, $\mathfrak{D}_0 ^1 = B \in \mathfrak{T}_1^1(M)$ (where $\mathfrak{T}_s^r(M)$ stands for all (r,s)-tensors on $M$), and we write $\mathfrak{D} = \mathfrak{D}_B$.

Here is the definition of a tensor derivation according to the book:

Definition (Tensor derivation). A tensor derivation $\mathfrak{D}$ is a set of $\mathbb{R}$-linear functions on a smooth manifold $M$ $$\mathfrak{D} = \mathfrak{D}^r_s:\mathfrak{T}_s^r \to \mathfrak{T}_s^r \quad\quad (r\geq 0, s\geq 0)$$ such that for any tensors $A$ and $B$:

(1) $\quad \mathfrak{D}(A \otimes B)= \mathfrak{D}A \otimes B+ A \otimes \mathfrak{D}B$

(2) $\quad \mathfrak{D}(\mathbf{C} A) = \mathbf{C}(\mathfrak{D} A )$ for any contraction $\mathbf{C}$.

My first problem is that I cannot see the intuition behind the definition whose notation is already cumbersome and I cannot find additional literature on the subject. Anyway, I believe a solution to the problem is given by the identity (1), for if $\theta$ is a $(1,0)$-tensor and $f$ a smooth real-valued function then $\mathfrak{D}(f)=\mathfrak{D}_0^0(f)=0$ by hypothesis and (1) becomes (hope this makes some sense): $$\mathfrak{D}(f \theta) = \mathfrak{D}(f) \otimes \theta + f \mathfrak{D}(\theta) = f \mathfrak{D}(\theta)$$ which I hope is enough to prove the necessity and sufficiency of $\mathfrak{F}(M)$-linearity.

Yet I cannot derive how it can be interpreted that $\mathfrak{D}_0^1$ is a (1,1)-tensor! Can anyone explain it? Does someone know a more comprehensive and introductory reference?.

Your argument to show that $D^1_0$ is $\mathcal F(M)$-linear if and only if $D_0^0=0$ using the product rule is completely correct. Now consider the properties of $D^1_0$ in this case: it is an $\mathcal F(M)$-linear bundle map $TM \to TM$, and thus $$B : (X,\omega) \mapsto \omega(D^1_0 X)$$ is an $\mathcal F(M)$-linear map $TM \otimes TM^* \to \mathcal F(M)$; i.e. a $(1,1)$-tensor. (Depending on your definition of $(1,1)$ tensor this may require the additional step of showing that $\mathcal F(M)$-linear maps on tensor products of the tangent bundle correspond to smooth tensor fields; but I assume you're aware of this correspondence.)

# How to show that two operators in the forms of vectors commute?

This is an exercise from Peskin&Schroeder's book. The exercise requires to show that $\textbf{J+}$ and $\textbf{J-}$ commute with each other. What is the exact meaning of commutation between operators that are the form of vectors? Do I have to just show that $[\textbf{J+}^i, \textbf{J-}^i]=0$? Or do I have to show that $[\textbf{J+}^i, \textbf{J-}^j]=0$? I am confused...

• Are you confusing 'vector operator' (i.e. an operator that acts on vectors) with 'operator that is a vector'? – Acccumulation Mar 15 '18 at 15:17
• I mean the latter. – Keith Mar 15 '18 at 15:18

in this specific case you have to show that $$[J_+^i,J_-^j]=0$$ meaning that every component commutes with every component.
• The above relation is more general than $[J_+^i,J_-^i]=0$. – G K Mar 15 '18 at 15:15

# Copper contamination

## Recommended Posts

Hi, I recently purchased '99.99%' pure silver and dissolved it in 6M nitric acid. I noticed the solution has a blue/green color, indicating copper impurity. Anyone have ideas on removal of copper contamination without losing much yeild? thanks.

##### Share on other sites

there are NOx gasses that when in Soln will also give this color, it may not Entitely be a copper contam.

##### Share on other sites

Yeah, I figures it could be dissolved NOx gasses. I slow heated the solution and a lot of Nitric acid fumes came out.. for quite some time. I heated until it was just a wet slush of crystals. It was still bluish. Added water and heated again etc.. The solution is still blue, but I know that the acid isn't all gone. Any quicker way for me to get rid of the dissolved gas?

##### Share on other sites

Im not 100% sure, I know Urea is used for dissolved NOx gasses though.

I cant be certain if it works with AgNO3 soln though?

if after crystalising its still blue though, then it probably IS copper.

in which case you can either ignore it OR try purify it.

##### Share on other sites

Last time I was doing this I precipitated the silver with sodium acetate and washed off the copper acetate (you lose Ag this way but you can always recover it as chloride).

If you want to get the silver then you can heat the acetate carefully so it decomposes. Since the acetate is slightly soluble you should be able to convert it to Ag2O with excess NaOH, wash it then redissolve it in HNO3.

##### Share on other sites

Silver will always be contaminated with copper. They are in the same column in the periodic table so they have somewhat similar chemical properties too. In addition, just the tiniest portions of copper ions in solution will provide a blue color. So while the coloring may be slightly blue, that doesn't mean that it is a very high % of copper.

If you dilute a solution with dissolved NOx gasses, then it becomes colorless at once. So, your blue color really is due to copper ions.

Just a check you could do: Take half a ml or so of your solution and add 5% household ammonia to this, until the liquid becomes clear again. If this liquid has a fairly strong royal blue color, then indeed you have copper in your solution.

If you have done this test, please do not store the liquid with ammonia. Either neutralize again with acid, or get rid of the liquid, but don't store it. Silver/ammonia complex slowly forms an explosive compound (fulminating silver).

# Math Help - Statistics Normal to Binomial Approximation

1. ## Statistics Normal to Binomial Approximation

65% of children (ages 12-17) keep their savings in a savings account. You randomly select 45 children and ask each if he or she keeps his or her savings in a savings account. Find the probabiltiy that at most 25 children will say yes.

I'm quite certain this is a normal to binomial approximation, in which the mean = np and the standard deviation is the square root of npq. This would make the mean = 29.25 and the standard dev = 3.2.

I started solving by finding the continuity correction for 25, making it P(x is less than/equal to 24.5). I then found the corresponding z-score with the formula: z = (x - mean) / standard dev. So I did (24.5-29.25) / 32 = -1.48. However, when I matched this z score with the corresponding area on the Normal Distribution Tables, it did not equal 0.1210, which is the correct answer from the answer key. I would appreciate it if someone could explain how to find the answer of 0.1210. Thanks very much for your time.

2. it should be $25.5$

you have to add $0.5$ instead of subtract it and you get $\Phi(-1.17) = 0.1210$

# Measure-preserving dynamical system

In mathematics, a measure-preserving dynamical system is an object of study in the abstract formulation of dynamical systems, and ergodic theory in particular.

## Definition

A measure-preserving dynamical system is defined as a probability space and a measure-preserving transformation on it. In more detail, it is a system

$(X, \mathcal{B}, \mu, T)$

with the following structure:

• X is a set,
• $\mathcal{B}$ is a σ-algebra over X,
• $\mu:\mathcal{B}\rightarrow[0,1]$ is a probability measure, so that μ(X) = 1, and
• $T:X\rightarrow X$ is a measurable transformation which preserves the measure μ, i. e. each measurable $A\subseteq X$ satisfies
$\mu(T^{-1}A)=\mu(A).\,$

This definition can be generalized to the case in which T is not a single transformation that is iterated to give the dynamics of the system, but instead is a monoid (or even a group) of transformations $T_{s} : X \to X$ parametrized by $s \in \mathbb{Z}$ (or $\mathbb{R}$, or $\mathbb{N} \cup \{ 0 \}$, or $[0, + \infty)$), where each transformation Ts satisfies the same requirements as T above. In particular, the transformations obey the rules

• $T_{0} = \mathrm{id}_{X} : X \to X$, the identity function on X;
• $T_{s} \circ T_{t} = T_{t + s}$, whenever all the terms are well-defined;
• $T_{s}^{-1} = T_{-s}$, whenever all the terms are well-defined.

The earlier, simpler case fits into this framework by defining Ts: = Ts for $s \in \mathbb{N}$.

## Examples

Examples include:

• μ could be the normalized angle measure dθ/2π on the unit circle, and T a rotation. See equidistribution theorem;
• the Bernoulli scheme;
• the interval exchange transformation;
• with the definition of an appropriate measure, a subshift of finite type;
• the base flow of a random dynamical system.

## Discussion

One may wonder why the seemingly simpler identity

μ(T(A)) = μ(A)

is not used. Here is the problem: suppose T : [0, 1] → [0, 1] is defined by T(x) = (4x mod 1), i.e., T(x) is the "fractional part" of 4x. Then the interval [0.01, 0.02] is mapped to an interval four times as long as itself, but nonetheless the measure of T −1( [0.04, 0.08] ) = [0.01, 0.02] ∪ [0.26, 0.27] ∪ [0.51, 0.52] ∪ [0.76, 0.77] is no different from the measure of [0.04, 0.08]. That hypothesis suffices for the proofs of ergodic theorems. This transformation is measure-preserving.

## Homomorphisms

The concept of a homomorphism and an isomorphism may be defined.

Consider two dynamical systems $(X, \mathcal{A}, \mu, T)$ and $(Y, \mathcal{B}, \nu, S)$. Then a mapping

$\phi:X \to Y$

is a homomorphism of dynamical systems if it satisfies the following three properties:

1. The map φ is measurable,
2. For each $B \in \mathcal{B}$, one has μ(φ − 1B) = ν(B),
3. For μ-almost all $x \in X$, one has φ(Tx) = Sx).

The system $(Y, \mathcal{B}, \nu, S)$ is then called a factor of $(X, \mathcal{A}, \mu, T)$.

The map φ is an isomorphism of dynamical systems if, in addition, there exists another mapping

$\psi:Y \to X$

that is also a homomorphism, which satisfies

1. For μ-almost all $x \in X$, one has x = ψ(φx)
2. For ν-almost all $y \in Y$, one has y = φ(ψy).

## Generic points

A point $x \in X$ is called a generic point if the orbit of the point is distributed uniformly according to the measure.

## Symbolic names and generators

Let $Q=\{Q_1,\ldots,Q_k\}$ be a partition of X into k measurable pair-wise disjoint pieces. Given a point $x \in X$, clearly x belongs to only one of the Qi. Similarly, the iterated point Tnx can belong to only one of the parts as well. The symbolic name of x, with regards to the partition Q, is the sequence of integers {an} such that

$T^nx \in Q_{a_n}$.

The set of symbolic names with respect to a partition is called the symbolic dynamics of the dynamical system. A partition Q is called a generator or generating partition if μ-almost every point x has a unique symbolic name.

## Operations on partitions

Given a partition $Q=\{Q_1,\ldots,Q_k\}$ and a dynamical system $(X, \mathcal{B}, T, \mu)$ , we define T-pullback of Q as

$T^{-1}Q = \{T^{-1}Q_1,\ldots,T^{-1}Q_k\}$

Further, given two partitions $Q=\{Q_1,\ldots,Q_k\}$ and $R=\{R_1,\ldots,R_m\}$, we define their refinement $Q \vee R$ as

$Q \vee R = \{Q_i \cap R_j| i=1,\ldots,k , j=1,\ldots,m , \mu(Q_i \cap R_j) > 0 \}$

With these two constructs we may define refinement of an iterated pullback

$\vee_{n=0}^N T^{-n}Q = \{Q_{i_0} \cap T^{-1}Q_{i_1} \cap ... \cap T^{-N}Q_{i_N} | i_l = 1,\ldots,k , l=0,\ldots,N , \mu(Q_{i_0} \cap T^{-1}Q_{i_1} \cap ... \cap T^{-N}Q_{i_N})>0 \}$

which plays crucial role in the construction of the measure-theoretic entropy of a dynamical system.

## Measure-theoretic entropy

The entropy of a partition Q is defined as

$H(Q)=-\sum_{m=1}^k \mu (Q_m) \log \mu(Q_m)$

The measure-theoretic entropy of a dynamical system $(X, \mathcal{B}, T, \mu)$ with respect to a partition $Q=\{Q_1,\ldots,Q_k\}$ is then defined as

$h_\mu(T,Q) = \lim_{N \rightarrow \infty} \frac{1}{N} H\left(\bigvee_{n=0}^N T^{-n}Q\right)$

Finally, the measure-theoretic entropy of a dynamical system $(X, \mathcal{B}, \mu, T)$ is defined as

$h_\mu(T) = \sup_{Q} h_\mu(T,Q)$

where the supremum is taken over all finite measurable partitions. A theorem of Ya. Sinai in 1959 shows that the supremum is actually obtained on partitions that are generators. Thus, for example, the entropy of the Bernoulli process is log2, since every real number has a unique binary expansion. That is, one may partition the unit interval into the intervals [0,1 / 2) and [1 / 2,1]. Every real number x is either less than 1/2 or not; and likewise so is the fractional part of 2nx.

If the space X is endowed with a metric, then the topological entropy may also be defined.

# Relative day of election start is wrong saying 'yesterday' instead of '2 days ago'

The election page lists the various phases in the right margin, including when those phases start/started.

Currently the UTC time is 2018-04-04 14:35 and the election phase started at 2018-04-02 20:00 which is almost 43 hours ago.... In UTC (and EST - my local timezone, if it matters), today is Wednesday, and the Election started at 20:00 UTC on Monday, but, the election page claims that the election started yesterday.

Clearly, the election did not start yesterday (Tuesday), it started on Monday... 2 days ago. The relative time for the day is wrong

• This is not just the election page, the same occurs all over Stack Exchange. "yesterday" is everything from 24 hours ago (inclusive) to 48 hours ago (exclusive). – Simon Forsberg Apr 4 '18 at 15:05

• Substantial experimental and theoretical efforts worldwide are devoted to explore the phase diagram of strongly interacting matter. At LHC and top RHIC energies, QCD matter is studied at very high temperatures and nearly vanishing net-baryon densities. There is evidence that a Quark-Gluon-Plasma (QGP) was created at experiments at RHIC and LHC. The transition from the QGP back to the hadron gas is found to be a smooth cross over. For larger net-baryon densities and lower temperatures, it is expected that the QCD phase diagram exhibits a rich structure, such as a first-order phase transition between hadronic and partonic matter which terminates in a critical point, or exotic phases like quarkyonic matter. The discovery of these landmarks would be a breakthrough in our understanding of the strong interaction and is therefore in the focus of various high-energy heavy-ion research programs. The Compressed Baryonic Matter (CBM) experiment at FAIR will play a unique role in the exploration of the QCD phase diagram in the region of high net-baryon densities, because it is designed to run at unprecedented interaction rates. High-rate operation is the key prerequisite for high-precision measurements of multi-differential observables and of rare diagnostic probes which are sensitive to the dense phase of the nuclear fireball. The goal of the CBM experiment at SIS100 (sqrt(s_NN) = 2.7 - 4.9 GeV) is to discover fundamental properties of QCD matter: the phase structure at large baryon-chemical potentials (mu_B > 500 MeV), effects of chiral symmetry, and the equation-of-state at high density as it is expected to occur in the core of neutron stars. In this article, we review the motivation for and the physics programme of CBM, including activities before the start of data taking in 2022, in the context of the worldwide efforts to explore high-density QCD matter.
• A new general purpose fixed target facility is proposed at the CERN SPS accelerator which is aimed at exploring the domain of hidden particles and make measurements with tau neutrinos. Hidden particles are predicted by a large number of models beyond the Standard Model. The high intensity of the SPS 400~GeV beam allows probing a wide variety of models containing light long-lived exotic particles with masses below ${\cal O}$(10)~GeV/c$^2$, including very weakly interacting low-energy SUSY states. The experimental programme of the proposed facility is capable of being extended in the future, e.g. to include direct searches for Dark Matter and Lepton Flavour Violation.
• Six of the key physics measurements that will be made by the LHCb experiment, concerning CP asymmetries and rare B decays, are discussed in detail. The "road map" towards the precision measurements is presented, including the use of control channels and other techniques to understand the performance of the detector with the first data from the LHC.

Yes. There was a bug.
I am sorry that : I use different symbol in the simulation and in the web page.
The cta in EJS code was not the same $\theta$ in the above equation, and the direction for rotation was positive for colckwise rotation.

I have modified the whole code and change all the convention back to normal.

cta in the EJS code is the same as $\theta$ now (i.e. maximum area mean cta=0;)
THank you for the bug report. It is fixed and the first simulation has been updated!

P.S. another bug was fixed, too. (the check box for the Efield show be [u]showE[/u] instead of [u]showBF[/u])
