Pythagorean theorem helped us create better maps. We use this theorem to find the shortest distance. It is a useful technique for architecture, woodworking, or other physical construction projects.

Logarithms helped us perform tedious calculations before there weren't any calculators. They are especially evident in science and measurement. When we talk about extremely small and large numbers, we always use logarithms. For instance, when we work on our sensitivity to light, earthquake significances, noise levels in decibels, acidity (pH), money growing with a fixed interest rate, bacteria growing in a petri dish, and radioactive decay, we use logarithms.

Calculus helped us turn away from mysticism and alchemy to rational science. It appears everywhere in modern science and technology whether we are modeling the rise in the fall of the stock market or determining exactly when a space rocket will arrive into Earth's orbit. Basically, calculus created the modern world. It holds incredible power over the physical worlds by modeling and controlling systems. It's the language of medical experts, scientists, engineers, statisticians, physicists, and economists. If a quantity or a system is changing, we can use mathematical modeling of calculus to analyze a system to find an optimal solution and predict the future.

Newton's Law of Gravity helped us understand the movement of the stars and planets. It's a key to understand the divine force, momentum, and many other laws.

The square root of minus 1 was invented to solve equations that have negative roots. Most of our modern tech depends on them. Although many people hated the complex numbers, i² was a great discovery and had a lot to do with the development of quantum mechanics. It brought up ideas that turned out to be very important.

Euler's formula helps us send rockets throughout space and understand DNA replication. It is an essential ingredient in finding solutions for network information. Euler's invention is a new way of thinking about shapes and space. It also provides a clear connection between geometry and the knot structure of a DNA.

Normal distribution transformed how we understand medical trials and how we gamble. It also changed almost all psychological and educational applications of our modern world. Statisticians and scientists use the normal distribution to measure reading ability, job satisfaction, surveys, IQ scores, blood pressure, measurement errors, etc...

It tells us what the Earth is made of and helps us find oil easier. It plays an essential role in electromagnetism, optics, fluid dynamics and heat transfer. Also, it lets us predict future dynamic properties such as energy and impulse.

You see this post thanks to these algorithms because the internet, WiFi, smartphones, computers, routers, almost everything that has a network inside uses Fourier transform algorithms. Fourier transforms are essential in signal processing. We can now compress thousands of information into a tiny dongle.

The Navier-Stokes equations are significant in terms of pure science and mathematics. The equation represents the governing equations of one model of fluid flow. The equation also tells us all the fast things in life can go even faster.

All modern wireless communications that we have today are related to Maxwell's equations. Those equations are the mathematical summary of electromagnetism.

It literally drove the industrial revolution and gives us efficient power generators. It also represents the relationships between heat and energy. For instance, it explains what happens in our cup of tea if we don't drink it for 5 minutes.

The relativity theorem is very important because it answered previously almost all the questions that remained unanswered. It changed the way we look time, space and gravity. It is everything for black holes, the big bang, nuclear power but also GPS on our phones.

This theorem changed the field of quantum physics. It made possible to work on quantum and calculate what would happen next. It is also essential for modern computer chips and lasers and cats.

Information theory means the entire internet. It literally models the human-machine communication process. This theory is now more important than communication itself.

Chaos theory helps us predict the weather better. It's the butterfly's fault for flapping its wings. The equation also predicts the growth rate of the butterfly population.

This equation models the massive growth and profits of the financial sector. Some people believe that the Black-Scholes equation caused the financial crisis of 2008-2009.

Thank you to all the students and teachers who participated in our very first global math art contest! We have now announced the list of finalists as well as the top 3 winners of each age category. All these beautiful graphs are also featured on www.desmos.com/art. COVID19 has impacted many schools recently. We are extending the deadline to April 30, so more students can participate.
In recent years, we've seen a growing number of classrooms around the world doing math art projects using Desmos. These projects involve using various equations and inequalities in our free Graphing Calculator to create some truly impressive pictures, often as a final project for a unit or even for the course.

We've been so excited about the beautiful and creative math art that is being produced with Desmos that we wanted to create a space for students from around the world to submit entries and win prizes for their hard work. So this year, we're running our first-ever Desmos Global Math Art Competition!

Any student aged 13-18 may submit a Desmos graph to the competition via their teacher or a parent. Judging will be based on three age categories:

13-14 years old

15-16 years old

17-18 years old

Your original art created in the Desmos Graphing Calculator. (Original means that (a) you made it yourself and (b) it doesn't contain any copyrighted images.)

Want to impress our judges? We're looking for submissions that have some combination of the following:

Creativity & Originality including:

Visual content

How you use the math you know

Delight. There are lots of ways to show this, such as:

Ten finalists in each of the three age categories will be selected by our in-house panel of judges. All 30 finalists' graphs will be featured on our website and will then proceed to a final round of judging by a panel of guest judges.

In each age category, the following prizes will be awarded:

First Prize: $500

Second Prize: $250

Third Prize: $100

All Finalists (including top 3 prize winners):

All 30 finalists, including the top three in each category, will receive:

Desmos T-shirts for the winning student and their teacher

A Desmos-sponsored pizza party (or equivalent) for the entire class

Students can submit their entries through the Graphing Calculator on Desmos.com. In addition, teachers can submit in bulk on behalf of their students. Here's a Google form where teachers and parents can submit entries. Although we will only accept one graph entry per student, our form allows a teacher to upload graphs for multiple students if they desire. All submissions must be made on or before April 30th, 2020 at 11:59 p.m. Pacific Standard Time. We will follow up by email with teachers or parents who submit graph entries that are selected to be finalists to ensure that we can properly credit the student.

All contestants must be ages 13-18. Submit graphs based on the age you will be on May 1.

We have excluded students under the age of 13 from this contest due to various international age restrictions in online privacy laws.

Each entry must be submitted by a responsible adult (teacher or parent), NOT by the student themself.

Each student may only enter one graph in the contest, although the responsible adult may submit multiple students' entries at the same time.

When submitting, Desmos will collect only the responsible adult's contact information along with students' graphs. Prior to announcing any finalists or winners, we will contact the responsible adult of each finalist to determine how to contact and credit the student.

All graph submissions must be created using desmos.com/calculator.

All graphs must be the original work of the student. We cannot accept submissions that include copyrighted images. Specifically, submitted graphs may not include the use of content that is not the intellectual property of the person who made the graph.

Before distributing prizes, we reserve the right to verify students' eligibility and application information. It is the teacher's responsibility to ensure their students abide by local data privacy laws.

Brand new to graphing with Desmos? Not so new, but want to learn more? Check out any of these links to get started.

Questions? Contact us at contest@desmos.com.
UPDATE
In response to recent questions, we'd like to clarify a few points:

1. We are accepting international submissions. In fact, we encourage them.

2. While you cannot submit graphs of copyrighted images, you may submit graphs of works that are in thepublic domain.

简体中文, 繁體中文, Dansk, Nederlands, Français, Deutsch (Österreich), Italiano, 日本語, 한국말, Norsk, Português (Brasil), Pусский, Español, Svenska, ไทย
