This dissertation explores the idea that laws of nature are tools for gaining and employing
information about the world.
In my first chapter, I focus on the Best System Account of laws of nature, according to
which the laws are those generalizations which form a deductive system best combining
strength and simplicity. I claim that we must focus on the applicability of laws to the sorts
of subsystems of the universe with which we interact and manipulate. This provides us
with the tools to develop new notions of informativeness and simplicity, and sheds light
on our preference for dynamic explanations.
