00:00:02.310 --> 00:00:06.750
Hi. Let's face it, life is about change, and

00:00:06.750 --> 00:00:11.470
mathematics quantifies it beautifully. Calculus

00:00:11.470 --> 00:00:15.410
can open our eyes to change at the smallest scales

00:00:15.410 --> 00:00:19.429
and shows how finite processes can approach the

00:00:19.429 --> 00:00:22.730
infinite. But rather than focus on the mathematics

00:00:22.730 --> 00:00:26.370
of change, I want to spend this week reflecting

00:00:26.370 --> 00:00:33.049
on how mathematics has changed me. Math has changed

00:00:33.049 --> 00:00:36.929
what I notice. It's changed how certain I need

00:00:36.929 --> 00:00:41.289
to be. It's changed where I place my effort and

00:00:41.289 --> 00:00:46.710
even what I allow myself to hope for. Mathematician

00:00:46.710 --> 00:00:50.689
Paul Lockhart describes mathematics as a search

00:00:50.689 --> 00:00:53.689
for beauty and understanding that leads us to

00:00:53.689 --> 00:00:57.409
a higher ground and a more encompassing view.

00:00:58.149 --> 00:01:01.609
I just love that image. When we climb to higher

00:01:01.609 --> 00:01:05.209
ground, the world below has not changed, but

00:01:05.209 --> 00:01:09.269
our view of it has. We see hidden connections.

00:01:09.930 --> 00:01:14.329
We recognize how one path meets another. What

00:01:14.329 --> 00:01:19.049
seemed random begins to reveal a pattern. And

00:01:19.049 --> 00:01:23.010
this is one way that math has changed me. Before

00:01:23.010 --> 00:01:26.709
learning a new mathematical idea, I often cannot

00:01:26.709 --> 00:01:30.920
imagine what there is to see. So consider proving

00:01:30.920 --> 00:01:33.719
that the square root of two is irrational. Now,

00:01:33.739 --> 00:01:36.420
at first, the question may not seem important

00:01:36.420 --> 00:01:40.859
or even really interesting. The proof can feel

00:01:40.859 --> 00:01:45.959
difficulty and foggy. How can we possibly prove

00:01:45.959 --> 00:01:51.719
it? And then something clicks. The contradiction

00:01:51.719 --> 00:01:56.480
comes into focus. The waters part. You see that

00:01:56.480 --> 00:02:01.359
it must be true. And after seeing it, you cannot

00:02:01.359 --> 00:02:07.040
unsee it. This is more than just acquiring information.

00:02:07.680 --> 00:02:11.840
Information adds to what we know. Understanding

00:02:11.840 --> 00:02:17.819
can change the person doing the knowing. Lockhart

00:02:17.819 --> 00:02:21.979
writes that mathematics is a way of constantly

00:02:21.979 --> 00:02:26.840
evolving and changing myself. Becoming, get this.

00:02:27.240 --> 00:02:31.840
reborn as a person who sees in a new way and

00:02:31.840 --> 00:02:36.740
cannot unsee. That is much larger than the vision

00:02:36.740 --> 00:02:39.620
of mathematics that many of us encounter in school.

00:02:40.280 --> 00:02:43.500
Math is often presented as a collection of procedures,

00:02:43.860 --> 00:02:47.199
memorize this formula, follow these steps, and

00:02:47.199 --> 00:02:50.780
then find the correct answer. Instead, Lockhart

00:02:50.780 --> 00:02:54.280
describes a playground of the mind, a place to

00:02:54.280 --> 00:02:58.270
explore patterns. to make connections, and discover

00:02:58.270 --> 00:03:03.090
unexpected beauty. I'll be honest, the more mathematics

00:03:03.090 --> 00:03:06.610
I learn, the more I understand what he means.

00:03:07.169 --> 00:03:11.610
Math invites me to pause and to look more closely.

00:03:11.770 --> 00:03:14.590
It makes me curious about structures beneath

00:03:14.590 --> 00:03:17.669
the surface. It reminds me that the first view

00:03:17.669 --> 00:03:21.610
is rarely the only possible view. It may not

00:03:21.610 --> 00:03:25.849
be the most revealing one. So this week, I will

00:03:25.849 --> 00:03:29.189
explore how math has taught me to find connections

00:03:29.189 --> 00:03:33.490
that enlarge my imagination and change how I

00:03:33.490 --> 00:03:37.090
think about abstraction and fairness. How it's

00:03:37.090 --> 00:03:40.789
challenged my beliefs about growth and connected

00:03:40.789 --> 00:03:44.449
me to a community. And finally, how it's shaped

00:03:44.449 --> 00:03:50.009
what I allow myself to hope for. The world is

00:03:50.009 --> 00:03:53.930
still the world, and I am still me. But mathematics

00:03:53.930 --> 00:03:57.849
keeps leading me to higher ground. Each time

00:03:57.849 --> 00:04:02.490
I climb, I return as someone who sees a little

00:04:02.490 --> 00:04:02.889
differently.
