Every day is a highlight when you study mathematics and physics, actually science in general.
I have always been fascinated by how things work in nature, and I like to question them until I understand where things came from. For example, what is the law that governs the most fundamental interactions? How does a massive object bend space and time? What happen in the universe with more than 4 dimensions?
Learning mathematics and physics allow me to access explanations for most of the questions one could ask about the universe at the most fundamental level. Of course, a lot of the time this learning process can be difficult and frustrating, but in the end the satisfaction of seeing things fit together logically and beautifully always outweighs the cost.
Studying at the University of Melbourne means I have had an opportunity to learn from some of the best in my chosen fields. Every day is a highlight when you study mathematics and physics, actually science in general.
