Understanding the human body is a team effort. That's where the Yachtel group comes in.

Researchers at Yachtolt have been delving into the secrets of probiotics for 90 years. Yacold also

partners with nature portfolio to advance gut microbiome science through the global grants for

gut health, an investigator-led research program. To learn more about Yachtold, visit yacult.co.com.

Ever wondered what math actually is? No? Well, mathematicians sure have.

In fact, it's a question they're still debating today.

You'd think that's something they'd have a handle on, but they really don't.

Is math an aspect of nature that we're discovering, or is it an invention of the human mind?

For science quickly, I'm Rachel Feltman.

And I'm Kyn Santos, your favorite math teaching drag queen.

Last week, Kine came on the show to teach us just how beautiful math could be.

This week, we're getting to know who math is on the inside.

We've talked about equations and numbers and theorems, but what really are those things?

Are mathematicians like scientists going out into the world to take measurements and form hypotheses,

or are they more like philosophers who sit in an armchair and think?

Apparently no one knows?

Well, there are definitely a couple different camps in this debate.

One school of thought is called intuitionism, which is the idea that math is all in our heads,

and any mathematical truth is only true insofar as we believe that it's true.

My take is that it just looks way too convenient if it was invented by us.

I mean, if it was just invented by us, we'd have to be pretty smart.
