Have you ever wondered how people in the war used to communicate without their messages getting intercepted by their enemies? Well before all the technological advances that we have today they would send encoded messages amongst themselves praying that the enemies never find the key needed to crack the code using linear algebra. Throughout my presentation I will give a brief overview as to what cryptography is, the issues with using matrices to encrypt messages as well as the Enigma which was a big contributing factor for German communication during WWII.

I took a class on Cryptography in high school that helped teach the basics on the subject. I am happy to hear about a real world application of this topic with such a large impact!

I am excited to hear your talk about cryptography! I have always been fascinated in how codes are developed, and then later cracked by others. I’m interested in learning more about the linear algebra behind these codes and what mathematical steps people take to break them.

Have I ever wondered how people in the war used to communicate without their messages getting intercepted by their enemies? Yes! and I am still figuring it out now. Taylor, I am very excited about this talk, I truly want to know what you have to say about cryptography and learn from it!

I found your talk very interesting. I did not know much about cryptography prior to your talk and did not know it had any correlation to linear algebra. I enjoyed learning about its use in the war and how its was such an important factor for communication. Great job!

I thought your talk was very interesting Taylor. I like how you also incorporated some history into your presentation and made it a little more “real life” and realistic. I did take Linear Algebra and I think it’s useful to know there are applications “outside” of math.
