Math is a human activity.
The first thing I do when I encounter a new piece of mathematics is note the name of the person who first created it. Then I go learn about them.
Not as a side curiosity. As the main method.
I learn their career, their constraints, the problems that obsessed them, the way they thought, the life they lived. I practice cognitive perspective-taking until I can roughly see the mathematics from inside their situation.
This is not optional for me. It is the foundation.
Because human understanding is driven by empathy.
When I can take the perspective of the person who made the idea, I invest more. I stay longer. I return to it. I care whether I actually understand it or am just performing understanding. Mathematics demands exactly that kind of sustained, honest effort. Without the human connection, I notice that I forget more easily and think less carefully. The ideas stay thinner.
This is why I built this:
It sits on top of the MacTutor History of Mathematics Archive from the University of St Andrews — one of the most valuable free resources in existence:

More than three thousand detailed biographies. Real lives. Real minds under real pressures.
I use it because I refuse to treat mathematics as a cold sequence of results that somehow appeared without authors. Every definition, every proof technique, every conceptual leap was made by a particular person in a particular time. When I ignore that person, I am studying a reduced version of the subject.
The highest understanding available is not the one that strips the human away. It is the one that keeps the human in view and still reaches the mathematics.
Learn the people.
The mathematics becomes denser, more memorable, and more fully yours.
That is how I study. That is the claim.
