“This book about scientists began with beef stroganoff,” Swaby explains. In 2013, a New York Times obituary mentioned the rocket scientist Yvonne Brill’s stroganoff recipe and the number of her children before getting around to her professional achievements. Outraged, Swaby became inspired to write this valuable collection of brisk biographical sketches of 52 women who made contributions in fields like medicine, genetics and physics. These scientists were brilliant, driven, resistant to criticism and, because few would hire or pay them, often forced to work for nothing.

The seismologist Inge Lehmann discovered that the earth has an inner core. Jane Wright, an African-American doctor, helped develop chemotherapy. Emmy Noether helped invent abstract algebra and create the equations to support Einstein’s general theory of relativity. Dorothy Crowfoot Hodgkin worked out the crystal structure of vitamin B12. When she won science’s highest honor, The Daily Mail announced: “Nobel Prize for British Wife.”

Some sketches correct earlier portrayals that emphasized their subjects’ ladylike qualities — for example, Florence Nightingale is presented here not just as a nurturing angel with a lamp, but as a pioneer in statistics.

Swaby tells the scientists’ stories with energy and clarity. Refreshingly, spouses and children are mentioned only when relevant — and the book is recipe-free. x

These Halls I've Walked a Thousand Times

by gigglyliam

Louis has always been a loner, by his own choice. He never enjoyed going to school and has dreamed of dropping out, regardless of the constant pleas of his mother, for ages. Harry is a new student tutor at school, quite the opposite of Louis. When the pair gets together, they learn about a lot more than just algebra.

Pwede ba kasi na algebra at statistics na lang yung math namin wag na calculus hays

There is no way to overestimate the huge impact the medieval Muslim world had on the development of modern science and technology. Algebra, the introduction of the zero and decimal notation, optics, astronomy, logarithms, medicine and anatomy, engineering, natural histories, ship building, the highly accurate preservation of formerly lost Greek and Roman texts and on and on and on.

Thank you for 50+ followers. I know I don’t make a lot of ask posts but it’s stressful when I have to do Algebra Honors homework and having to answer your questions, so thanks for bearing with me.

Basically how i think of my algebra

anonymous asked:

i know this one guy at my school whos a leo and he's such a fuckboy omggg he wont leave me alone and the worst part is i have to sit next to him in algebra and the teacher wont let me move :/// ((distressed scorp))

id be distressed too tbh

I think every tv show should hire an obsessed fan to prevent continuity errors. Someone to go, “well that doesn’t work because in s2e4 you did x so you can’t possibly do y without doing z or you’ll contradict x”

Modern AU Lucina never tells anyone when her birthday is. No one can know the truth. *NO ONE*.

(Except Gerome and Laurent. Gerome can’t even construct a joke let alone a 4/20 joke, and Laurent isn’t a douchebag, so they’re safe. Severa absolutely cannot know.)

**Linear transformations**

Matrices and matrix multiplication reveal their essential features when related to *linear transformations*, also known as *linear maps*. A real *m*-by-*n* matrix A gives rise to a linear transformation R^{n} → R^{m} mapping each vector x in R^{n} to the (matrix) product Ax, which is a vector in R^{m}. T(vector(x)) = (ax+cy; bx+dy)

The matrix A is said to represent the linear map *f*, and A is called the *transformation matrix* of *f (*containing the
constants that define the linear transformation), where a, b, c, and d are numbers defining the linear transformation.

Such as T :R^{n} → R^{n}, then T is
associated with a square n×n matrix. One can calculate the determinant
of such a square matrix, and such determinants are related to area or
volume. It turns out that the determinant of a matrix tells us important
geometrical properties of its associated linear transformation. Det (A) = a.d-b.c, The square increase area by a factor of |Det (A)|

(A linear transformation on **R**^{2} given by the indicated
matrix. The determinant of this matrix is −1, as the area of the green
parallelogram at the right is 1, but the map reverses the orientation, since it turns the counterclockwise orientation of the vectors to a clockwise one)

**Horizontal shear with m=1.25**

**Horizontal flip**

**Squeeze mapping with r=3/2**

**Scaling by a factor of 3/2**

*Rotation by π/6 ^{R} = 30°*
