Google’s signature ranking algorithm “PageRank” is heavily based on linear algebra! Read the above book to find out more!

An engaging introduction to vectors and matrices and the algorithms that operate on them, intended for the student who knows how to program. Mathematical concepts and computational problems are motivated by applications in computer science. The reader learns by doing, writing programs to implement the mathematical concepts and using them to carry out tasks and explore the applications. Examples include: error-correcting codes, transformations in graphics, face detection, encryption and secret-sharing, integer factoring, removing perspective from an image, PageRank (Google’s ranking algorithm), and cancer detection from cell features. A companion web site,

`codingthematrix.com`

provides data and support code. Most of the assignments can be auto-graded online. Over two hundred illustrations, including a selection of relevant xkcd comics.

Chapters: The Function, The Field, The Vector, The Vector Space, The Matrix, The Basis,Dimension, Gaussian Elimination, The Inner Product, Special Bases, The Singular Value Decomposition, The Eigenvector, The Linear Program

## World Cup fans need math to figure out scenarios

World Cup fans need math to figure out scenarios

RIO DE JANEIRO (AP) — Every four years, the World Cup forces fans to remember their math lessons.

Working out what each team needs from its final match to finish in the top two of a group and advance to the knockout rounds takes some algebra knowledge and powers of prediction.

After Brazil and Mexico played to a scoreless draw on Tuesday, the calculation became clear: Both teams just need to draw in their next matches to advance with five points in Group A. Croatia, which beat Cameroon Wednesday, would get to six points by beating Mexico. So a draw with Cameroon would still get Brazil through with five points. If Mexico beats Croatia, Brazil would advance even if it loses. But if Mexico and Croatia draw, and Brazil loses — then it gets complicated with tiebreakers.

## Shifts must be made in education system to prepare young for future: Heng Swee Keat

SINGAPORE: Education Minister Heng Swee Keat has said that two important shifts must be made in the education system in order to prepare the young for the future.

In a Facebook post on Friday evening, Mr Heng said firstly, the education system must help the young acquire deep skills and integrate theory with practice through applied learning.

Secondly, the system should make it easier for students to continue learning in their areas of strength and interest, and encourage lifelong learning.

Mr Heng said the education system needs to better link the interest and strengths of students to jobs of the future.

He explained that when students develop a deep interest, when their imagination is captured, they can go on to do wonderful things.

## Mathematician gives evidence at the O.J Simpson trial, helped find diamonds and now is determining the cause of cancer.

Who says Mathematics is useless? It can be useful one day in your career, or just for increasing your general knowledge.

Mathematician Professor Terry Speed wins PM’s science prize

The man who last night won the Prime Minister’s Science Prize agrees maths is “not sexy” but it saw him give evidence at the O.J Simpson trial, helped find diamonds and now is determining the cause of cancer.

Mathematician Professor Terry Speed was called as an expert witness for O.J. Simpson in the famous 1995 murder trial where he helped explain to the jury how statistics underpinning DNA worked.

Simpson was acquitted after a trial that lasted more than eight months because his lawyers were able to persuade the jurors that there was reasonable doubt about the DNA evidence.

Forty five years ago Professor Speed testified at the trial of Ronald Ryan, the last man to be hanged in Australia.

He had to explain the geometry of the trajectory of bullets in the case.

In an extensive career the 70 year old statistics whiz has helped determine the size and distribution of Argyle diamonds and looked at kangaroo genomics.

Right now he is working at the cutting edge of medical science helping scientists develop statistical tools to understand the huge volumes of information coming from the human genome.

Work he’s done for a company on a thyroid cancer diagnostic test could help prevent thousands of people from having their thyroids removed unnecessarily.

At present some thyroid tests are inconclusive and tumours are removed even though they turn out to be benign leaving the patient taking hormone replacement therapy for the rest of their lives.

Some of his work is in developing tools that find which genes or gene characteristics may cause cancer if they are switched on or off.

Professor Speed says part of the reason so many people don’t want to study maths and science is they don’t see its potential.

He’s spent his life applying mathematical theories to crime, farming, mining and medical science.
