RSA is an algorithm used by modern computers to encrypt ad decrypt messages. This algorithm uses two different keys in which one can be public but the other one must be private.

Epidemiology is the science behind public health. Graphs help predict population data and disease spread.

Quantum mechanics is very complex, but we used the main ideas of each component. We studied distance conversions and wave-particle duality and everything in between.

How do you communicate with a friend in complete secrecy while standing in a room full of people? Elliptic-curve cryptography (ECC) is an approach to public-key cryptography based on the algebraic structure of elliptic curves over finite fields.

What's the difference between a coffee mug and a donut? Well, in Classification of Surfaces, we learned that they are essentially the same.

Knot Theory is the mathematical study of knots that has applications in many distinct areas of mathematics and science including algebra, geometry and physics. Knot theory is very important It is used in science fields such as the study of DNA.
