“There is much here to excite admiration and perplexity.”—Lord Rayleigh

AMS Feature Column

“These web essays are designed for those who have already discovered the joys of mathematics as well as for those who may be uncomfortable with mathematics. Mathematics is a fast growing and evolving subject. The domain of ways that mathematics is being applied is growing by leaps and bounds. Examples include CT scans, audio CDs, face recognition systems, and cell phone technology. Our goal is to share our excitement about these developments with you.”


“Chalkdust is a mathematics magazine. It’s not a journal, and it’s not a textbook. It’s a collection of articles, features and pictures that we think are interesting, fun, or thought-provoking.”


“This MAA publication offers a wealth of resources to help you teach mathematics using its history.”


“… about the fun, interesting, and beautiful side of math. I chose projects that I thought were nifty. Some projects amazed me when I first saw them. Others struck me with their elegance and beauty. And some illustrate mathematical concepts in a cool way.”

A monthly magazine from the American Mathematical Society, including a monthly survey of news and short summaries of articles about mathematics in the popular press.

Mathematical Circles Topics

“Mathematical Circles are for students of high school age or younger who want to increase their abilities to reason about mathematical problems. Students who study in circles learn to do mathematical olympiad-style problems (essay or proofs, not quick answer).”

The site includes handouts that can be used by teachers.

Mathematical Imagery

“Explore the world of mathematics and art, send an e-postcard …”

Mathematical Moments

“The Mathematical Moments program promotes appreciation and understanding of the role mathematics plays in science, nature, technology, and human culture. Download this series of pdf files to use as teaching resources and to promote awareness of mathematics to students, colleagues, and attendees at meetings and special events.”

Mathematics Archives - Topics in Mathematics

“In these pages, you will find links to various WWW resources on Mathematics. They are organized by topics.”

Mathematics Awareness Month

“Mathematics Awareness Month is held each year in April. Its goal is to increase public understanding of and appreciation for mathematics.” The site includes theme essays and posters.

Mathematics in Education and Industry

“Mathematics in Education and Industry was founded in the early 1960s and is an independent UK curriculum development body. MEI is committed to improving Mathematics Education and is involved in a range of activities to fulfil this aim.”


“The puzzling weblog of recreational mathematics.”

Maths Careers

“This site was produced by the Council for the Mathematical Sciences. The CMS is currently running a number of projects under the banner of "maths careers", aimed at enlightening students from 11 upwards about the opportunities available to students of maths and stats. These subjects improve students' employment prospects and open up many fascinating careers, but they suffer from an image problem and are seen as unpopular and difficult.”

Maths in the City

“These pages contain two walking tours of Oxford and London that explore some of the mathematical features in the cityscape.”


“The web's most extensive mathematics resource.”

Plus magazine

"Plus is an internet magazine which aims to introduce readers to the beauty and the practical applications of mathematics. Plus provides articles and podcasts on any aspect of mathematics, covering topics as diverse as art, medicine, cosmology and sport, a news section, showing how recent news stories were often based on some underlying piece of maths that never made it to the newspapers, reviews of popular maths books, and puzzles for you to sharpen your wits. We have a regular interview with someone in a maths-related career, showing the wide range of uses maths gets put to in the real world. And all past content remains available online, which besides making for good browsing is, we hope, a useful resource for maths school students and teachers."

Practical Uses of Math And Science

“Practical Uses of Math And Science – PUMAS (poo' · mas) – is a collection of one-page examples of how math and science topics taught in K-12 classes can be used in interesting settings, including everyday life. The examples are written primarily by scientists and engineers, and are available to teachers, students, and other interested parties via the PUMAS Web Site. Our goal is to capture, for the benefit of pre-college science education, the flavor of the vast experience that working scientists have with interesting and practical uses of math and science …”

Science Lives

“The Simons Foundation proudly presents a series of extended interviews with some of the giants of 20th-century mathematics and science. This collection, organized in collaboration with Hugo Rossi of the University of Utah, provides an opportunity to watch these great men and women discuss their lives and their thinking about science and our world.”

Teacher Resources on Line

“The purpose of these resources is to provide material which teachers of mathematics can use in their classrooms.”

The Griddle

“Delicious grid-based puzzles created by David Millar.”

The Institute of Mathematics and its Applications

“The Institute is the professional and learned society for qualified and practising mathematicians. Its 5000+ members work in industry, commerce, the public sector and education.

Operating under Drexel's School of Education, our mission is to provide resources, materials, activities, person-to-person interactions, and educational products and services that enrich and support teaching and learning in an increasingly technological world.”

The Mathematical Tourist, by Ivars Peterson

“… an occasional series devoted to "cool stuff" that I encounter while browsing the world of mathematics and computer science. I'll peek at new developments in math and its applications, and I'll revisit old puzzles, famous problems, and historic events—anything mathematical that happens to catch my eye. I hope you'll find something of value in these brief, informal forays into the world of math.”
