In 2012, a Japanese mathematician named Shinichi Mochizuki announced that he finally knew the ABCs. He wasn't talking about the Roman alphabet-he has known English for most of his life. He was talking about a mathematical statement called "the abc conjecture." (In mathematics, a conjecture is a statement that some mathematicians believe to be true, but no one has proved for certain. When it is proved for sure, it is called a theorem.)
Mochizuki studies number theory, a branch of mathematics. Mathematics is an incredibly broad, diverse subject. Mathematicians study everything from the random way stock markets and electrons seem to move to the properties of exotic shapes in unimaginable dimensions.
But if you ask someone on the street what a mathematician does, the guess will probably be closest to what a number theorist does. They study the properties of numbers, especially the positive whole numbers: 1, 2, 3, and so on.
Connecting Multiplication and Addition
Number theorists do a lot more than count. They try to understand relationships between numbers. If you've taken algebra, you may have seen an equation that looks something like y=3x+4, or even y = mx + b. All those letters indicate variables. The expression y = 3x + 4 represents all the possible pairs of numbers that satisfy that relationship, which ends up looking like a straight line. If you substitute a number, such as 2, for x in the first equation, you can find that y=3x2+4, or 10.

HOUSE OF CARDS
TRY THE PERFECT EXPERIMENT—AND THEN REFLECT ON HOW IT WENT.
ACCIDENTALLY Delicious
Have you ever been really hungry, but there wasn't much to eat in your kitchen? Did you throw together a bunch of stuff you had on hand and were pleasantly surprised when it tasted good?
IS YOUR SOCIAL MEDIA FEED TOO PERFECT?
EVERYONE'S LIFE CAN APPEAR PERFECT ON SOCIAL MEDIA. On YouTube, Instagram, Snapchat, and similar apps, people tend to share their happiest, most picturesque moments. They carefully compose any text to get the message just right. They use filters and enhancements to glam up images and videos. The app sorts the posts with the most likes and comments to the top. The end result? All you see of others' lives is the best of the best.
