Your extensive posting history on r/birdswitharms and your old fanfiction-heavy livejournal are both one tiny math problem away from becoming public knowledge. That math problem is prime number factoring, and the new era of quantum...

It’s been a pretty cool year for science around the globe, and we here at SciShow like to highlight the superlatives: some of the biggest, oldest, fastest, and most amazing discoveries of 2016.

A beutiful derivation of a formula for pi. At first, 1-1/3+1/5-1/7+1/9-.... seems unrelated to circles, but in fact there is a circle hiding here, as well as some interesting facts about prime numbers in the context of complex numbers.

Do periodical cicadas "know" how to calculate prime numbers? One of the strangest life cycles in all of biology, explained!

Certain cicada species in North America emerge from the ground by the millions every 13 or 17 years. But why those specific intervals? Are cicadas secretly prime-number-loving mathematicians?!

In this video, we will learn about Java arrays, which store multiple values in a single variable instead of creating separate variables for each value.

This video explains what prime numbers are and how to find out if a number is a prime or non-prime (composite number). Practice questions and answers are at the end of the video.

This video explains what prime numbers are and answers the question, "Is 1 a prime number?" In addition to the definition and explanation of what prime numbers are, I have included a practice problems as well.

In this video, the concept of prime numbers is explained clearly and concisely up to the number 10. Viewers are guided through identifying prime numbers by demonstrating which numbers can only be divided by one and themselves.

This video covers what prime and composite numbers are, and how we can tell whether a particular number is prime or composite. Key points: - Prime numbers are only divisible by themselves and 1. - Composite numbers are any number that...
