re: 17 Equations that changed the world

Ah yes, brings back some fond memories of undergrad where I barely use any of the three levels of calculus required at LSU.

If I’m working on an application or systems programming requirement, where you deal with design of a system or a website with given requirements differential equations are very rarely used. However, when working on an application with computer graphics, you might come across a situation where you need to solve a differential equation involving motion.

Another domain, where scientific computing is required you have to simulate a physical event by numerically solving a differential equation describing their physical behavior. Mechanism simulation, numeric solving requires the application of differential equations, especially PDE’s, Partial Differential Equations.

Set Theory and Boolean Algebra are are used more on my end throughout my day to day. Boolean Algebra is used more widespread to refactor logical IF statements.

Surprised Bayes’ theorem or DeMorgans Law isn’t on the list. Bayes’ Theorem is the concept behind most, if not all, spam filters used in Java. You use De Morgan's Law when optimizing and checking your conditionals. Public-Key Cryptography is why online transactions are secure and wouldn't be possible without concepts like the Binomial Theorem and Fermat's Little Theorem.
