Einstein Simplified


The lex parsimoniae (“law of parsimony or “law of succinctness”):

“Entia non sunt multiplicanda praeter necessitatem.”

“Entities should not be multiplied beyond necessity.”

“All things being equal, the simplest solution tends to be the best one.”

Occam’s razor


“Everything should be made as simple as possible, but not simpler.”

“The supreme goal of all theory is to make the irreducible basic elements as simple and as few as possible without having to surrender the adequate representation of a single datum of experience.”

Albert Einstein


“Simplicity is the ultimate sophistication.”

Leonardo da Vinci

Big Science vs. Little Science


“The scientist does not study nature because it is useful;
he studies it because he delights in it,
and he delights in it because it is beautiful.
If nature were not beautiful, it would not be worth knowing,
and if nature were not worth knowing,
life would not be worth living.”

Jules Henri Poincaré
