What Is Trigonometry?

Trigonometry is a branch of mathematics that studies relationships between the sides and angles of triangles. Trigonometry is found all throughout geometry, as every straight-sided shape may be broken into as a collection of triangles. Further still, trigonometry has astoundingly intricate relationships to other branches of mathematics, in particular complex...

What Is Symmetry?

In geometry, an object exhibits symmetry if it looks the same after a transformation, such as reflection or rotation. Symmetry is the underlying mathematical principle behind all patterns and is important in art (used in architecture, pottery, quilting and rug making), mathematics (relating to geometry, group theory and linear algebra),...

Properties of Pascal’s Triangle

Pascal’s triangle is a never-ending equilateral triangle of numbers that follow a rule of adding the two numbers above to get the number below. Two of the sides are “all 1's” and because the triangle is infinite, there is no “bottom side.” It is named for Blaise Pascal, a 17th-century...

What Is Topology?

Topology is a branch of mathematics that describes mathematical spaces, in particular the properties that stem from a space’s shape. Many of the shapes topologists deal with are incredibly strange, so much so that practically all everyday objects such as bowls and pets and trees make up a small minority....

Euler’s Identity: 'The Most Beautiful Equation'

Euler’s identity is an equality found in mathematics that has been compared to a Shakespearean sonnet and described as the most beautiful equation. It is a special case of a foundational equation in complex arithmetic called Euler’s Formula, which the late great physicist Richard Feynman called in his lectures our...

Tau Day: Should Pi Be Downgraded?

June 28. National Paul Bunyan Day, National Insurance Awareness Day, National … Tau Day? Today (June 28) is the unofficial holiday Tau Day, meant to celebrate the number tau, that works out to approximately 6.28, or the ratio of a circle's circumference to its radius. While pi may be the...

The 11 most beautiful mathematical equations

(Image credit: Shutterstock/R.T. Wohlstadter)Mathematical equations aren't just useful — many are quite beautiful. And many scientists admit they are often fond of particular formulas not just for their function, but for their form, and the simple, poetic truths they contain. While certain famous equations, such as Albert Einstein's E =...

Who Invented Zero?

Though people have always understood the concept of nothing or having nothing, the concept of zero is relatively new; it fully developed in India around the fifth century A.D., perhaps a couple of centuries earlier. Before then, mathematicians struggled to perform the simplest arithmetic calculations. Today, zero — both as...

Mathematicians Awarded $3 Million for Cracking Century-Old Problem

Editor's Note: This story was updated at 3:15 a.m. E.T. on Monday, Dec. 11 Two mathematicians have each earned the (massive but countable) sum of $3 million for a proof that could one day help scientists understand extra dimensions. Christopher Hacon, a mathematician at the University of Utah, and James...

Famous Mathematician Joseph Fourier Would Have Been 250 Today. Here's Why He Matters

March 21 marks the 250th birthday of one of the most influential mathematicians in history. He accompanied Napoleon on his expedition to Egypt, revolutionized science's understanding of heat transfer, developed the mathematical tools used today to create CT and MRI scan images, and discovered the greenhouse effect. His name was...

Creator of 'Grand Unified Theory of Mathematics' Wins Prestigious Math Prize

A mathematician who developed what some consider the grand unified theory of mathematics has won one of the most prestigious prizes in mathematics. Robert Langlands, an emeritus professor at the Institute for Advanced Study at Princeton University, has won the Abel Prize, a prestigious mathematics prize that honors a lifetime...

This Biologist Cracked a Problem That's Stumped Mathematicians for 68 Years

An amateur mathematician just partially solved a problem that has vexed mathematicians since 1950. Aubrey de Grey — a biologist better known for trying to radically extend human life and for predicting that the first person to live to be 1,000 years old has already been born — has published...

This Man Won the Top Prize in Mathematics — Then Someone Immediately Stole It

Yesterday (Aug. 1), University of Cambridge mathematician Caucher Birkar won the Fields Medal — the highest prize in mathematics, awarded every four years to a small group of mathematicians age 40 or younger. The award came with a 14-carat gold medal and 15,000 Canadian dollars (about $11,500). According to the...

Mathematician Claims He Solved 160-Year-Old Math Problem. Critics Say Probably Not.

An unsolved 160-year-old math problem may finally have a solution — but critics are wary. Michael Atiyah, a prominent mathematician emeritus at the University of Edinburgh, announced yesterday (Sept. 24) at the Heidelberg Laureate Forum in Germany that he had come up with a simple proof to solve the Riemann...
