Joseph received his Bachelor's in Mathematics from Texas State University. He was originally a chemistry major but a semester of real analysis ignited a fascination with abstract mathematics and proof. He changed from a chemistry major to a math major. His favorite branch of mathematics is topology. When he saw an animation of a coffee cup transforming into a donut and back again he became obsessed with it. His mathematical background gives him the tools to do an amateur study of physics and astronomy to his heart's content. He is also passionate about nature conservation with a focus on reptiles and amphibians. He volunteers with groups to reach out to the public about the importance of protecting these animals and their habitats. At home he is typically surrounded by cats. He enjoys working through his math books and unwinds by playing video games.
Favorite number: Euler's number e. It shows up in the mathematical modeling of many natural phenomenon such as nuclear decay, metabolic activity, and heat flow. It also shows up in unexpected places such as calculating interest and signal processing. Furthermore the trigonometric and hyperbolic functions can all be written in terms of e. Understanding of functions with powers of e is critical for success in calculus, differential equations, analysis, and beyond.
Favorite math joke: An infinite amount of mathematicians walk up to the counter. The first mathematician says I'll have a soda and give each person next in line half of what the previous person got. The clerk says "you mathematicians sure are a crazy lot" and pours out two sodas.
