&lt;br /&gt;
Math is like science. It is precise to the maximum. So whenever I write something in math I always want to make sure &lt;br /&gt;
that I am clear enough. Sets are sets functions are functions numbers are numbers. Math is also like art. It is a series&lt;br /&gt;
of arguments that we present to people to convince them what we believe is true. To some extent it is like politics or like&lt;br /&gt;
philosophy. I like to make my arguments simple, supplemented with diagrams and illustrations so that whenever I read&lt;br /&gt;
it I will be happy to believe what is written is true. However I still sin sometimes quoting big theorems without&lt;br /&gt;
actually fully understand them. But I try my best not to and present the simplest arguments that anybody could understand.-Kai&lt;/div&gt;</summary>
