# Galois-theoretic derivation of the cubic formula

We are trying to find the roots $r_{1},r_{2},r_{3}$ of the polynomial $x^{3}+ax^{2}+bx+c=0$. From the equation

 $(x-r_{1})(x-r_{2})(x-r_{3})=x^{3}+ax^{2}+bx+c$

we see that

 $\displaystyle a$ $\displaystyle=$ $\displaystyle-(r_{1}+r_{2}+r_{3})$ $\displaystyle b$ $\displaystyle=$ $\displaystyle r_{1}r_{2}+r_{1}r_{3}+r_{2}r_{3}$ $\displaystyle c$ $\displaystyle=$ $\displaystyle-r_{1}r_{2}r_{3}$

The goal is to explicitly construct a radical tower over the field $k=\mathbb{C}(a,b,c)$ that contains the three roots $r_{1},r_{2},r_{3}$.

Let $L=\mathbb{C}(r_{1},r_{2},r_{3})$. By Galois theory we know that $\operatorname{Gal}(L/\mathbb{C}(a,b,c))=S_{3}$. Let $K\subset L$ be the fixed field of $A_{3}\subset S_{3}$. We have a tower of field extensions

# Homework Help: Maxwell stress tensor to calculate force (EM)

1. May 5, 2015

### fluidistic

1. The problem statement, all variables and given/known data
A sphere with dielectric constant $\varepsilon$ and radius R is placed inside a homogenous external electric field $\vec E_0$. The sphere is divided in 2 hemispheres such that their common interface is orthogonal to the external field. Using the energy-momentum tensor, calculate the attraction force between the 2 hemispheres.

2. Relevant equations
I think they meant "Maxwell stress tensor" instead of "energy-momentum tensor" since the latter seems to be related to special relativity and has nothing to do with this part of the course which is based on the book of Zangwill.
In page 81 in Zangwill's book, there's a formula to calculate the force via Maxwell stress tensor which eventually reduces to $\vec F = \varepsilon_0 \int_S dS[(\hat n \cdot \vec E ) \vec E -\frac{1}{2}(\vec E \cdot \vec E)\hat n]$. The thing is that I'm not really understanding this formula, especially the part about "S" the surface of integration. There's an example of a charged balloon in the book but it's not clear to me either.
3. The attempt at a solution
I tried to brainlessly apply the formula in hope of falling over the solution so that I could hope for a reverse engineering in order to understand it, but I failed.
Here's my attempt:
The electric field inside the sphere is $\vec E_{\text{int}}=\frac{3}{2+\varepsilon}\vec E_0$.
I choose spherical coordinates $(r, \theta , \phi)$.
So $\hat n=r\cos \phi \sin \theta \hat i + r \sin \theta \sin \phi \hat j + r \cos \theta \hat k$.
Also, $\vec E _{\text{int}}=\frac{3}{2+\varepsilon}|\vec E_0|\hat k$.
I picked the surface of integration as a hemisphere, so $r=R$, $\theta:[0, \pi/2]$ and $\phi :[0,2 \pi]$.
So I plugged and chugged $\vec E_{\text{int}}$ and $\hat n$ inside of the formula given above. As soon as I obtained a non vanishing result in the $\hat i$ direction, I stopped my calculations, I know something is wrong but I can't avoid this result unless I change the surface of integration but I've no idea which one to pick... So I'm stuck here.
I expect the force to be in the $\hat k$ direction only due to the symmetry of the problem, of course.
Any help is appreciated, thanks!

2. May 7, 2015

### MisterX

I don't know how you are getting a non vanishing result in the i-hat direction. All but the k-hat direction should vanish after integrating with respect to phi. What is the vector expression you got for your integrand?

3. May 7, 2015

### fluidistic

Yeah that's what I was expecting.
$$\vec F = \varepsilon_0 \int_S dS [\left ( \frac{3R\cos(\theta)|\vec E_0|}{2+\varepsilon} \cdot \frac{3|\vec E_0|\hat k}{2+\varepsilon} \right ) -\frac{1}{2}\left ( \frac{3}{2+\varepsilon} \right ) ^2 |\vec E_0|^2R(\cos \phi \sin \theta \hat i + \sin \theta \sin \phi \hat j + \cos \theta \hat k) ]$$
Now focusing only on the term with $\hat i$ (due to length of the expression), I get that it's worth a constant times $\int_0^{2\pi}\int_0^{\pi/2} \cos \phi \sin ^2 (\theta) d\theta d\phi$.
Oops my bad you're right, it's worth 0... same for the term with $\hat j$... Thanks a lot!

4. May 7, 2015

### fluidistic

Ok I reach $\vec F=\left ( \frac{3}{2+\varepsilon} \right )^2\varepsilon_0 |\vec E_0|^2 \pi \frac{a^3}{2}\hat k$.
I integrated over a single hemisphere. I am guessing that I should integrate over the 2 hemispheres separately and then add the result in order to get the total force. Overall I guess that the total force is actually twice the one I reached (assuming the math is ok).
Therefore my answer would be $\vec F=\left ( \frac{3}{2+\varepsilon} \right )^2\varepsilon_0 |\vec E_0|^2 \pi a^3 \hat k$.

# Hours deceased

By Murray Bourne, 02 Feb 2007

There is an incoming link to squareCircleZ from the blog Horas Mortas by Maria in Lisbon, Portugal. The Babelfish translation of the blog title is "Hours Deceased". Hmm - there is a lot to think about in that title.

Maria has a piece about Sophie Germain (in Portuguese), who was a late 18th / early 19th century mathematician.

The translation goes (I have tidied it up a bit):

Lagrange presented her works [to the committee] under the pseudonym of M. LeBlanc. She made an impression and he wanted to meet with the student. He was amused when he saw that the author of the work was a woman, and became her mentor. With a man to present it, Sophie entered then in the circle of mathematicians and scientists.

In 1804 she started to correspond with the Gauss mathematician who was moved when discovering who the correspondent was.

Sophie Germain was a revolutionary who fought against the preconceptions and the absence of formal education obtaining to become a celebrated mathematical one.

It appears that the post is based on this article from Biographies of Women Mathematicians (in English). This quote says a lot about 19th century attitudes to women and learning:

Her parents felt that her interest [in mathematics] was inappropriate for a female.

With little formal education and lots of discouragement, she did well. It is a pity that there is still societal pressures working against success in mathematics − for boys and girls.

### 6 Comments on “Hours deceased”

1. maria says:

Thank you for your post. My post is based as you say on this article and others that confirm it.
Horas mortas is the hours we have nothing to do unless think . It is the title of a poem writen by a portuguese poetess. Sorry for my english.

2. Murray says:

Thanks for the information, Maria. Your English is great!

How is life for women mathematicians in Portugal? I was surprised when I first came to Singapore that (at least among teachers of mathematics) women mathematicians are confident and are seen in a positive way by the society.

This was not the case in Australia, where there were very few female mathematicians and there was a lot more discouragement than enthusiasm for women to take on such a role.

3. Vinod says:

Women seem always to have had a hard time as mathematicians.

When Emmy Noether applied for a position at GÃ¶ttingen University, the faculty was afraid that this was the end of things as they knew it.

David Hilbert's response to the outcry: "I do not see that the sex of the candidate is an argument against her admission. After all, we are a university and not a bathing establishment."

4. Murray says:

Yes, Vinod. And it is not only mathematicians. It has been tough for women to get into university, even. From Wikipedia's article on Newnham College, Cambridge:

[In 1872] women were allowed into lectures, albeit at the discretion of the lecturer. By 1881, women were allowed to sit university examinations, and in 1921 were awarded "titles" as a result, although they would have to wait until 1947 before they were awarded degrees, and 1958 before they achieved equal rights to their male counterparts.

5. Murray says:

In Canada.com's Gazette, there was a recent article, "Women learn better, faster". They talk about how women are beginning to dominate universities in Canada. It is the same trend in the US and Australia. Carmen Au, a 25-year old student says:

"When I was about 10, I remember, a family acquaintance asked what my favourite subject was and I said 'math.' He said girls shouldn't be interested in math, that English was more like it. I told my parents, who told me to ignore it."

Seems to me that encouraging women to learn has powerful outcomes.

But wait, there's more! (Why is it that this topic keeps landing on my radar...?)

Apparently Bush is going to spend \$136 billion to "encourage innovation and strengthen the ability of the U.S. to compete in the global economy." The article Fixing Engineering's Gender Gap argues that some of those greenbacks should go into encouraging women into engineering.

"...fewer than 20 percent of engineering graduates are women, according to the National Science Foundation."

The key issues raised by women in focus groups included:

# Lack of role models.
# Lack of female mentors.
# Discrimination.
# Balancing work and family.
# Perception and self-promotion

Sounds familiar.

6. maria says:

Today is dificult to a young person believe or realize what were the difficulties a woman suffer to enter in a man worl: it looks like something of the past. It is good see the Math and science history. In Portugal forty years ago the girls who studied in university were few. They studied to be a teatcher, they studied literature, history ,languages and the boys would be engineer or another scientific career . Now a days is quite different: the most part of the students in scientific courses are woman.Tere is no descrimination. But they must go to another country( boys and girls)because here they dont have opportunities to a career in investigation.

# Using Integration by Parts

## Homework Statement

indefinite integral dx/((e^x)(sqrt(1-e(-2x))))
using integration by parts evaluate the integral.

## Homework Equations

integral u*dv = u*v- integral v*du

## The Attempt at a Solution

To be completely and entirely honest i am not even sure where to start with this problem. I have finished other integration by parts homework questions in this assignment but this one i can't find something to choose for u and dv that will work out correctly.:grumpy: I have been at this problem alone from almost 2 hours. Any help would be greatly appreciated.

## Answers and Replies

Are you sure it wasn't

$$\sqrt {1-e^{-2x}}$$

instead of $$\sqrt {1-e(-2x)}$$, since that is a very strange way of writing it.

If so, just remember that $$\frac {1}{e^{x}} = e^{-x} = \sqrt {e^{-2x}}$$ and set $$u = e^{-2x}$$

Last edited:
It was supposed to be
1/ $$\sqrt {1-e^{-2x}}$$

**How did you get that equation to show up that way? I just copy and pasted what you had to make it work this time and was curious how i would go about doing that.

Last edited:
There is a \frac command in LaTex. To use it just type \frac {numerator}{denominator}

So your problem would show up as:

$$\int {\frac{dx}{e^{x}\sqrt{1-e^{-2x}}}$$

**Also check out this guide to LaTex typesetting

We define the collision frequencycollision frequency, $${\widetilde{\nu }}_{12}$$, as the number of collision per unit time between a single molecule of type 1 and any of the molecules of type 2 present in the same container. We find $${\widetilde{\nu }}_{12}=N_2\pi {\sigma }^2_{12}\left\langle v_{12}\right\rangle$$. If there are $$N_1$$ molecules of type 1 present in a unit volume of the gas, the total number of collisions between type 1 molecules and type 2 molecules is $$N_1$$ times greater. For clarity, let us refer to the total number of such collisions, per unit volume and per unit time, as the collision rate, $${\rho }_{12}$$. We have
${\rho }_{12}=N_1{\widetilde{\nu }}_{12}=N_1N_2\pi {\sigma }^2_{12}\left\langle v_{12}\right\rangle =N_1N_2{\sigma }^2_{12}{\left(\frac{8\pi kT}{\mu }\right)}^{1/2}$

Decimal 0.75 as a fraction

What is 0.75 as a fraction in simplest form?

Answer: Decimal 0.75 as a fraction is 3/4 (¾)
0.75=
3
/
4

The fractional equivalent of 0.75 is 3/4 (¾)

Explanation of 0.75 Decimal to Fraction Conversion

In order to find the simplest fraction form of 0.75 first we need to write out decimal number 0.75 as fraction. Any number can be written as a fraction quite simply - just divide it by 1:

0.75 =
0.75
/
1

Next we need to get rid of the decimal part in our numerator so that the numerator in our fraction becomes a whole number. To do so we need to multiply both numerator and denominator by 100 (because there are 2 digits after the decimal point in the number 0.75):

0.75 × 100
/
1 × 100
=
75
/
100

Now we need to simplify our fraction to its simplest form. To do so we have to find the Greatest Common Factor (GCF) of 75 and 100. To find the GCF of 2 numbers you can use our GCF Calculator . GCF of 75 and 100 is 25. So in order to simplify our fraction we need to divide both numerator and denominator by 25:

75 ÷ 25
/
100 ÷ 25
=
3
/
4

That's it! 0.75 as a fraction in it's simplest form is equal to 3/4 (¾).

### Pi Day Sudoku Is Back!

March 9, 2010

You laughed in 2008.

You cried in 2009.

This March, from the producers of Naked Sudoku*, comes…

## PI DAY SUDOKU 2010!

As in past years, there is also a contest** associated with the puzzle, but who needs a contest when you’ve got a puzzle with the (conjectured) minimum number of clues (18 – in this puzzle, the first 18 digits of π) for a unique solution of a rotationally symmetric puzzle?  Here’s a printable PDF so you can take the puzzle with you to your next meeting lunch break.

Happy solving!

*Brainfreeze Puzzles, in case you were wondering.
**Also as in past years, we will not allow a solution to be posted until after the June 1 deadline.  Thank you for your cooperation.

### Happy Pi Day!

July 22, 2008

Happy Pi Day!!!

22 July is celebrated throughout (much of) the world as Pi Day, for the ratio 22/7 is a reasonably accurate rational approximation to the number π.

Pi Day is also celebrated on March 14, in those parts of the world who would abbreviate today’s date ( July 22, 2008 ) as 7/22/2008, since March 14 becomes 3/14 under such a scheme. According to Wikipedia (“So you know it’s true!”™), only a handful of countries follow this scheme. Most would abbreviate using either a little-endian scheme ( 22/7/2008 ) or a big-endian scheme ( 2008/7/22 ). The amount of space on Wikipedia devoted to a flamewar discussion about the relative merits of each scheme is astounding.

There are many days when I’m happy to be a mathematician, and not a copy editor for an international open content network based encyclopedia.

### Musical Pi, Part 3

March 26, 2008

Finally, the last four tracks in the suite of π-based music, composed by Jon Turner. (See also part 1 and part 2.)

8. Quest 4 Pi 2
MM=288 175mm 2:26
The first part is the same as 1; after the central cadence on C, the harmony no longer changes, and this forms a coda. The guitar continues to shred the rhythm over the final C7sus harmony.
9. Circle of the Great Spirit 2
MM=72 94mm 4/4 5:13
19 digits of π, theme of 1, in 4/4 with variations:
Introduction: 457/0.
Theme: 31848/9 0/5 949/1 3B/6 9186/2 64/1 -4/0 5/0 7/0.
Variation 1: each duration is divided into two half-length durations.
(Variation 2: is track 1 above, CGS1, in triple meter, 3/4.)
Variation 3: durations are divided into 4, creating a rhythmic crescendo typical of classical variations.
Theme: closing anthem.
Coda: 457/0 eight times.

Bonus track(s):

10. Arc Tango X
MM=170 784mm 4/4 18:06
Same as 2, but continues way beyond 160 to 768.
Long jam already, in flux, could go way beyond…
11. Quest 4 Pi complete

### Musical Pi, Part 2

March 19, 2008

Following up (at long last) on Musical Pi, Part 1, we present the remaining nine pieces (plus bonus tracks!) in the suite of music based on π, composed by Jon Turner, professor of musical composition at Nazareth. (see also part 1 and part 3) Click for the next 7 pieces.

### Lemon Pie Recipe

March 13, 2008

Yes, it’s March 13 and the countdown to Pi Day has begun! While people gather round and sing Pi Day Songs, you can make Aunt Mattie’s Lemon Pie. Aunt Mattie worked for my grandmother’s family, and was known for her pies: chocolate, butterscotch, and lemon. My grandmother once carefully measured and wrote down the ingredients that Aunt Mattie used, giving the recipe shown here. (Hmmm. It looks like this card could well be that original recipe. I am, perhaps, the messiest cook I know.) Click here to see Godzilla demonstrate how to cook a lemon pie.

### Pi Day Sudoku

March 12, 2008

In honor of Pi Day, Brainfreeze Puzzles (“we turn coffee into puzzles”) created a Pi Day Sudoku on a 12×12 grid.

The rules are a little different from standard Sudoku, in part because the blocks are jigsaw pieces rather than 3×3, and in part because the first 12 digits of π are used instead of the standard 1-9. Each row, each column, and each colored block (“jigsaw region”) contains the first 12 digits of pi

3 1 4 1 5 9 2 6 5 3 5 8

in some order. In particular, there are two 1s, one 2, two 3s, one 4, three 5s, one 6, no 7s one 8, and one 9.

As a bonus, on Brainfreeze’s Pi Day site there are instructions for how to (possibly) win an autographed book by completing the puzzle. Woo hoo!
The contest is over: you can find the solution here.

### Musical Pi, Part 1

January 27, 2008

Jon Turner, a professor of musical composition here at Nazareth, has composed a suite of music based on π! (see also part 2 and part 3) As he says:

The basic idea is to use the decimal expansion of pi to give an unendingly varying [but] related series of notes.

The first step was to convert π to base 12 (to match the chromatic musical scale), so

$\pi = 3.1415926535\ldots_{10} = 3.184809493B\ldots_{12}$

(where B represents decimal 11 in base 12). Starting with C at 0, he gets

$\pi = E\flat D\flat A\flat E A\flat C\ldots$

### French Silk Pie

January 3, 2008

This pie recipe comes from Terri, one of my grad school roommates, and I like to make it because I think of her and I smile. Of course, I also like to make it because it’s a delicious, scrumptious chocolate pie. And it’s easy to make, which is especially good if you’ve invited 20 students over for a pre-Putnam dinner and somehow got it into your mind to make 6 pies. So without further ado….

### Chocolate-Peanut Butter Ice-cream Pie

November 30, 2007

In preparation for the dozen or so students who are coming over for dinner tonight in honor of Saturday’s Putnam exam, I made the pie pictured here. I made a bunch of pies, actually, because pie is really good. And then I thought “Pie is a mathy kind of dessert. We need a pie category on our Blog!” The premier recipe is this Chocolate-Peanut Butter Ice-Cream Pie by Heather Eckman. Click here for the recipe

On the interference of the weight and boundary contour for algebraic polynomials in weighted Lebesgue spaces. II

Ukr. Mat. Zh. - 2017. - 69, № 12. - pp. 1633-1651

We continue to study the estimation of the modulus of algebraic polynomials on the boundary contour with weight function, when the contour and the weight function have certain singularities with respect to the their quasinorm in the weighted Lebesgue space. In particular, the exact estimates were obtained for polynomials orthonormal on the curve with respect to the weight function with zeros on the same curve.

On the Behavior of Algebraic Polynomial in Unbounded Regions with Piecewise Dini-Smooth Boundary

Ukr. Mat. Zh. - 2014. - 66, № 5. - pp. 579–597

Let G ⊂  be a finite region bounded by a Jordan curve L := ∂G, let $\Omega :=\mathrm{e}\mathrm{x}\mathrm{t}\overline{G}$ (with respect to $\overline{\mathbb{C}}$ ), let Δ := {w : |w| > 1}, and let w = Φ(z) be the univalent conformal mapping of Ω onto Δ normalized by Φ (∞) = ∞, Φ′(∞) > 0. Also let h(z) be a weight function and let A p (h,G), p > 0 denote a class of functions f analytic in G and satisfying the condition $${\left\Vert f\right\Vert}_{A_p\left(h,G\right)}^p:={\displaystyle \int {\displaystyle \underset{G}{\int }h(z){\left|f(z)\right|}^pd{\sigma}_z<\infty, }}$$ where σ is a two-dimensional Lebesgue measure.

Moreover, let P n (z) be an arbitrary algebraic polynomial of degree at most n ∈ ℕ. The well-known Bernstein–Walsh lemma states that * $$\begin{array}{cc}\hfill \left|{P}_n(z)\right|\le {\left|\varPhi (z)\right|}^n{\left\Vert {P}_n\right\Vert}_{C\left(\overline{G}\right)},\hfill & \hfill z\in \Omega .\hfill \end{array}$$

In this present work we continue the investigation of estimation (*) in which the norm ${\left\Vert {P}_n\right\Vert}_{C\left(\overline{G}\right)}$ is replaced by ${\left\Vert {P}_n\right\Vert}_{A_p\left(h,G\right)},p>0$ , for Jacobi-type weight function in regions with piecewise Dini-smooth boundary.

Jensen’s alpha is a statistic that is used to test return-predicting factors for potential use in portfolio construction. For example, suppose that we index data for asset $i$ at time $t$ by $(i,t)$. Let $r$ denote return and $f^j$ denote a return predicting factor. Suppose we have data for securities $i=1,2,\ldots,I$ at times $t=1,2,\ldots,T$, and suppose there are $J$ return predicting factors. Then for each time $t$, we can regress returns across firms on all return predicting factors. That is, for fixed $t$, we estimate the equation:

$r_{i,t}= \sum_{j=1}^J \beta^t_j f^j_{i,t} +\varepsilon_i$

across firms $i$. Note that by including a constant factor by setting some $f^j=1$ for each security and time $(i,t)$, we can account for exposure to the market. We now ask the question: on average, how much does unit exposure to factor $j$ increase or decrease returns independently of the other factors? For example, in a factor model that includes both size and earnings, unit exposure to size may also increase exposure to earnings because large companies tend to have higher earnings; however we wish to quantify how much unit exposure to size increases or decreases returns in a way that is not accounted for by earnings. To answer this question, we estimate the equation:

$\beta^t_j = \alpha_0 + \sum_{k\neq j} \alpha_k \beta^t_k + \varepsilon_t$

across time $t$. The quantity $\alpha_0$ is Jensen’s alpha. There are several commonly cited examples of Jensen’s alpha. CAPM alpha refers to Jensen’s alpha that is obtained when the factor model consists only of some factor $j$ that you wish to test, and a constant. CAPM alpha is the additional return you obtain from unit exposure to $j$ that is not accounted for by CAPM. Three-factor alpha, also called Fama-French alpha, is obtained when you include a constant, size, and value factors. Four-factor alpha additionally includes a momentum factor.

### 3 Responses to Jensen’s Alpha

1. Anonymous says:

What information does Jensen’s alpha add that a simple test of significance would not? For example, if factor X always significantly predicts returns in the cross-section, even accounting for factor Y, then when would X have a negative alpha? More importantly, even if X has a negative alpha, why would you omit X from your model given that it accurately predicts returns?
