"The most incomprehensible thing about the world is that it is comprehensible." ——Albert Einstein
Every picture in the illustration part is a question. Including mathematics, physics, chemistry, astronomy, etc., the art works ask: "why our world can be calculated". For example, why the Pythagorean theorem is a2+b2=c2, why is the golden ratio 0.618, why π is 3.14, why Euler's formula can be associated with several constants, why Maxwell's equations can unify Light, electricity, magnetism, why Mendeleev's periodic table inspiration come from dreams and so on.
