We know what you’re thinking.
“How can this be a serious geometry book?”
“What’s with all the graphics?”
“Can I actually learn it this way?”
And we know what your
Your brain craves novelty. It’s always searching, scanning, waiting for
something unusual. It was built that way, and it helps you stay alive.
So what does your brain do with all the routine, ordinary, normal things
you encounter? Everything it can to stop them from interfering with
the brain’s real job—recording things that matter. It doesn’t bother
saving the boring things; they never make it past the “this is obviously
not important” filter.
How does your brain know what’s important? Suppose you’re out for
a day hike and a tiger jumps in front of you, what happens inside your
head and body?
Neurons fire. Emotions crank up. Chemicals surge.
And that’s how your brain knows.
This must be important! Don’t forget it!
But imagine you’re at home, or in a library. It’s a safe, warm,
tiger-free zone. You’re studying. Getting ready for an exam. Or
trying to learn some tough math thing that your teacher is going to
test you on tomorrow.
Just one problem. Your brain’s trying to do you a big favor. It’s trying
to make sure that this obviously non-important content doesn’t clutter
up scarce resources. Resources that are better spent storing the
really big things. Like tigers. Like the danger of fire. Like how you
should never again snowboard in shorts.
And there’s no simple way to tell your brain, “Hey brain, thank
you very much, but no matter how dull this book is, and how little
I’m registering on the emotional Richter scale right now, I really do
want you to keep this stuff around.”
