So, this is our  mobile soundscape exhibit.

Soundwaves are just  vibrations in the air.

As long as you have curiosity,  you know there's life.

I get that same feeling as I do  when I look up into the stars.

As a kid I would run  through the hallways

and I would hear them  practising Mexican traditional music.

I went to a Catholic school,  and the nun who had the Spanish class

Here we are at the plaza,  La Plaza Principal.

My mum didn't know Spanish  and my father didn't know English,

but they were able to communicate at least with music.

But his curiosity sometimes  got him in trouble.

I was not a good student in high school. I didn't have any expectations,

I wasn't looking at universities or anything like that.

I started at Cabrillo and  I didn't know what engineering was.

As far as I was concerned, it was like a mechanic or something like that.

But I started taking some  maths classes and it was different.

You know, there's lots  of types of students.

The majority of the students,  they want the equation

And then there are students who actually try to understand.

I would always question things,  I would always wonder,

how light works, why the waves  are crashing the way they do.

And when you start looking  at physics, and learning about

these soundwaves are just  vibrations in the air,

and how we can  represent those mathematically,

where they connect students  to research institutions.

It was really interesting what  Danelle and John were doing.

That's an important part  of working on audio;

you have to have an understanding  of the way sound works.

Light may reach a couple of  hundred metres in the ocean.

It's not a surprise that many life  forms use sound for communicating.

Blue whale is the largest animal  to have ever lived on earth,

They vibrate your body,  they're incredible to hear.

The scientists at MBARI wanted to figure out a way to listen in

and to count how many  blue whales there were.

involves recording  audio from the ocean.

too much information for a human  to try to look at and listen to.

We were able to turn  those sounds into spectrograms,

which are just images or mappings  of what sound looks like.

And fed those images into TensorFlow, this machine-learning tool.

Machine learning is  getting the computer

It allows us to take  a mammoth pile of data

and distill it  into something meaningful,

We want to understand how and  when they're using all these calls,

because that can help us  understand their ecology.

We could answer a lot of questions  about the way we are affecting

the marine environment  and how we can help conserve it.

Daniel was key in  developing the software

Daniel started  with the artistry of sound,

and found a meeting place  with the science of sound.

Ultimately, both of those experiences, they're from the same source.

That is sound energy varying  in frequency through time.

The whales are communicating  something to each other.

I don't know what it is,  but it made me think about

Just like going back to my parents  and how they met each other.

When I was a kid, I didn't think  I was going to be a scientist or engineer.

And especially as I grew up, I didn't think I was capable of doing it.

School was hard for me, and it still is hard for me.

I find myself so interested  in a lot of different things.

But knowing that  I'll never stop learning,
