Something You Should Know - When Personal Achievement Becomes Toxic & What You Never Knew About the Ocean
Episode Date: November 6, 2023Why are the numbers 1, 2 and 3 across the top of a telephone keypad but across the bottom of a calculator? That’s one of three interesting questions that get answered as I begin this episode. The ot...her 2 have to do with portholes and time. Source: Ivan Semeniuk, co-author of Why Don't Penguins' Feet Freeze? (https://amzn.to/3sf8muM) There is nothing wrong with achievement. But if you believe that you are only as valuable as your achievements, that can be a problem. If we let our success or lack of success define who we are at any point in time, it can demotivate you and make you feel as if you don’t matter. Joining me to talk about this is Jennifer Wallace. She is an award-winning journalist and social commentator and frequent contributor to The Wall Street Journal and The Washington Post. She is author of a book called Never Enough: When Achievement Culture Becomes Toxic—And What We Can Do About It (https://amzn.to/49jkdIQ) What goes on beneath the surface of the ocean is amazing - much of which I bet you never knew. The oceans cover 70% of the planet and yet most of us know little about what goes on down there. Here to give a fun and interesting tour of the workings of our oceans is Helen Czerski is a physicist and oceanographer at University College London’s Department of Mechanical Engineering and author of the book The Blue Machine: How the Ocean Works (https://amzn.to/3scCyXo). Listen as she explains why the ocean is so salty, why there is really only one ocean and so much more. What if there was one simple thing any woman could do to motivate the man in her life? Well there is according to one marriage expert. In fact, he says this one little thing works every single time if women would just try it.

Today on Something You Should Know,
the answers to three questions you've probably wondered about,
about calculators, portholes, and time.
Then, toxic achievement.
It's when you define yourself by your success.
The messages perhaps that you got growing up were that you're only as good as your success.
So when you're not successful, that's when you can really, really struggle.
When we really couple our worth to our achievements, it makes us less resilient.
Also, one simple thing women can do to motivate any man.
And a peek below the surface at what's going on in our oceans.
And there's a lot going on.
I do think that we need to get away from this idea
that the dominant thing we know about the ocean is that it's mysterious.
You know, if you want mystery, look into space, it's empty.
The ocean is doing so many interesting and beautiful things.

Today, Something You Should Know with Mike Carruthers.
Hello, welcome to Something You Should Know.
I'm going to start today's episode with three questions.
Three questions you may have wondered about, didn't know the answers,
and now you'll have the answers.
Number one.
On a telephone keypad,
the lowest numbers,
one, two, and three,
are across the top.
On a calculator,
they're at the bottom.
Why are they different?
Well, they each travel down
different evolutionary roads.
The calculator descended from the old adding machine, which had lower numbers at the bottom.
The touch-tone telephone descended from the dial telephone, which had lower numbers at the top.
Why are the windows on many ships round?
They're portholes rather than windows.
Actually, on many old wooden boats, the windows were square.
But when ships switched to metal hulls, that's when things changed.
When you cut a rectangle or a square into a piece of metal,
the metal is subject to more fatigue at those corner points.
Naval architects quickly learned that round portholes eliminate the problem.
And the third question, what time is it in the North Pole?
And the answer is, any time you want it to be.
Theoretically, all time zones converge at the North and South Poles,
so there is technically no time.
And that is something you should know.
It's hard to argue with the concept of achievement.
We are taught to achieve, in school and at work.
Achievement is good. It's how we get ahead.
We judge our success by our achievements.
But can achievement become toxic?
Can we become so wrapped up in our achievements that they define us? That
may not be so good. And it seems to happen quite a bit. Joining me to talk about this
is Jennifer Wallace. She is an award-winning journalist, social commentator, covering parenting
and lifestyle trends. She used to work at 60 Minutes, and she is a frequent contributor
to the Wall Street Journal and the Washington Post.
She's author of a book called Never Enough, When Achievement Culture Becomes Toxic and What We Can Do About It.
Hi, Jennifer. Welcome to Something You Should Know.
Oh, thanks so much for having me on.
So, state your case here, because, you know, achievement seems like a good thing.
So, at what point does achievement become not a good thing?
Achievement becomes toxic when our sense of self is so deeply intertwined with our successes
or our failures.
That's when it becomes toxic, when we only feel as good as our next achievement, or we feel as bad as our
failure. So when our self-esteem, when our sense of self, when our sense of worth rests on our
accomplishments, it becomes toxic. So it would seem to me, though, that we are wrapped up in
our achievements, that achievements are a big part of us,
that if you, for example, get a job you've always wanted and you finally achieve that
and then, say, the company goes out of business or you get fired or whatever,
that's going to be a huge blow.
You're going to feel terrible about that because your achievements are a big part of you.
So at what point do you say it's toxic?
And at the other point, there's a line where you feel horrible and that's okay.
Yeah, that's obviously a normal reaction, right?
So mental health is not about having positive emotions all the time.
But as psychologists point out, having good mental health means that you have a reaction that's appropriate to what you're going through.
Where it would become toxic is if getting fired really becomes an indictment of your worth and you sink into a depression or you turn to substances to cope.
That the messages perhaps that you got growing up were that you're only as good as your success.
And so when you're not successful, that's when you can really, really struggle.
When we really couple our worth to our achievements, it makes us less resilient.
And where does this come from?
Why are people feeling this way?
What I believe is at the root of much of our anxiety and depression,
the loneliness epidemic, is this unmet need to matter.
And mattering is a psychological construct that's been around since the early
1980s. It was an idea, a concept that was initially conceived by Morris Rosenberg, who
is the social psychologist who brought us the idea of self-esteem in the 1960s. And what he found in the early 80s was that
kids who did well, who enjoyed healthy self-esteem, felt like they mattered to their
parents, that they were important and significant. What I am seeing now in my own research, what I'm
reading from national surveys, is that there are many people in the world who feel like they don't
matter, meaning they don't feel valued by anyone, by family, by friends, at the workplace. They feel
easily replaced. They don't feel known or seen or heard. And these are basic human needs that are going unmet. And when, you know,
researchers who study it say that after the drive, the human motivation for food and shelter,
it is the instinct to matter that drives human behavior for better and for worse.
I get that people don't feel like they matter
and that it would be good if they did. But what does that have to do with achievement? I mean,
I know I get it, but I want you to make the case because it seems like we're talking about two
different things. We're not. Right. Okay. So when we talk about achievement that is excessive
and felt like excessive pressure, what we are talking about is the idea that our sense of self
is contingent on our achievements, that we only matter when we achieve. So the kids that I met who seemed to be suffering the most
were kids who felt like their mattering was completely contingent on their performance,
that they only mattered if they got good grades or if they made the A-team or they got the starring
role. They felt that only certain people in this world mattered. And then if they weren't
performing at a high level, then they didn't actually matter.
The other group of kids who were suffering that I met were kids who got the messages
at home that they mattered.
They heard from their parents that they were important and significant, but no one ever
relied on them or depended on them to give back in any way other than to themselves and their own resumes.
And so what these kids lacked was what I call social proof that they mattered.
They heard it in words, but they didn't see how they actually made a positive impact on the world around them. But what you just said sounds like an argument
to try to achieve, to use that feeling of not mattering as fuel to show the world that you
can achieve, that you can do something, that you do matter. And one way to be acknowledged
as mattering is for people to see what you've accomplished, what you've achieved.
Oh, I think it's the opposite of that. I'll talk about myself. I am extremely ambitious.
I am a high performer. I get a lot of joy out of my achievements. But what I am driven by
is what I call a healthy fuel. And that healthy fuel is that I don't feel defined by my achievements or my
failures. I'm able to reach higher for bigger goals because I know if I don't succeed, it's
not an indictment of who I am versus other people I know in my life who have a very fragile sense
of mattering, a very fragile sense of self-worth, that they only feel
worthy when they're achieving. And so this can backfire. They are less likely to reach for super
high goals because they are holding on to the little mattering that they have. I suppose what
we're talking about, if you really zoom out, is about values and how they impact achievement and our well-being.
And so your values of having this healthy outlook on achievement comes from where?
Was it from your parents, from your...
Yeah, there's a social psychologist, Gregory Elliott, who writes,
what gets in early gets in deep. So our first sense of self-worth and self-esteem is
not created in a vacuum. It is what researchers call a social barometer to see how we are doing
in the eyes of others. And the first people that we get this sense of self-worth from are our parents, the feedback that they give
us, the signals they send us about whether or not we are worthy just for being who we are.
And I will tell you, I grew up with a deep sense of mattering. And I didn't realize how unusual
that was until I went out into the world. And I was working in very hyper-competitive environments,
like 60 Minutes. And many of my colleagues really struggled with feeling worthy. One colleague said
to me, you're only as good as your next story here. That is not a great environment to raise children in, to be working in ourselves.
It seems that we live in a culture where it's a never-ending wheel, that if you want to
achieve, one way you achieve and you get opportunities to achieve is because of your past achievements,
your experience achieving other things.
So it never ends. And like with school, I have a son who at-risk group. And these are kids attending
what researchers call high achieving schools. Those are public and private schools around the
country where kids go off to competitive four-year colleges. Those kids are now at risk, meaning they
are two to six times more likely to suffer from anxiety and depression
and substance abuse disorder than the average American teen. That is a problem. When the kids
in our culture who are given so many opportunities are doing as poorly as students living in poverty, there is something upside down wrong in our culture.
We're talking about achievement, toxic achievement, and the human need to matter.

Please be alert, as trains can pass at any time on the tracks.
Remember to follow all traffic signals. Be careful along our tracks and only make left
turns where it's safe to do so. Be alert, be aware, and stay safe.
So Jennifer, it seems like there is some attention being paid to what you're talking about in the sense that we hear things about, you know, mental health days and self-care and the four-day work week and, you know, flexible schedules, that there's some attempt to address this? Or is that, in your view, just lip service? No, I think there is an attempt to address it. I think you're absolutely right.
There's certainly more of an awareness, but I do believe that we are sold a bill of goods when it
comes to the multi-billion dollar wellness industry. You can't download a meditation app
or have a mindful day at work. Resilience rests fundamentally, this is according to decades
worth of resilience research, on the strength and depth of our relationships. The problem I saw,
and I saw it over and over again, was not that adults today didn't have friends. The adults I
interviewed had friends. What they didn't have was the time and the bandwidth
to deepen those friendships so that they could be sources of support when needed. So in order for
parents, for example, to act as first responders to our kids' struggles, we need one or two people
in our lives outside of the home and i want to underscore that
because our in-home relationships are already overtaxed trying to be these you know one
household villages so really it's one or two people outside of our home that we can open up to
that we can feel heard that we can feel seen that know we matter. And that is what builds up our
resilience. Do you think, you know, if you stopped people on the street and asked them
if they saw this as a problem in their life, that they would agree with you? Or because,
you know, your life is your life, you don't really have anything to compare it to,
that they don't see this as a problem. This is just the way things are.
No, there have been studies done asking the very question, do you feel like you matter?
Do people notice you?
Do people depend on you?
And a very large percentage of adults and youth do not feel like they matter and they're aware of it.
This is an instinct to matter. This is something that we have all evolved to feel.
So you can feel like you don't matter. You can feel invisible, but you notice, you know that you're, I mean, think about it in your own life.
I mean, there have been times, our sense of mattering fluctuates throughout our lifespan.
So you could be a busy young mother and actually feel like you matter too much because you're exhausted and your kids are pulling at you all day long.
And then your children could leave and go to college and start their own lives. And you wonder if you're not sort of feeling like you matter in
other domains of your life, you can really struggle with not feeling like you matter.
People in retirement can feel like they matter at work and then feel invisible when they're out of
the workplace. No one is asking anything of them. No one is depending on them anymore.
I don't know if that's the actual question you would ask people, but if you ask somebody,
do you think you matter? I mean, there's kind of a tendency to say no because of the way the
question is served up. And it isn't like you don't matter to everybody. Maybe you don't feel like you
matter at work, but you, nope. I don't think too many people feel like they don't matter to anybody, to anywhere.
Oh, I think you're wrong.
I think this is part of our devastating loneliness epidemic.
I don't have the data in front of me, but there have been national surveys asking people,
if you were to go in for surgery, would you have someone to call you to
pick you up? I mean, there are so many lonely people in the world. I don't think it's the
majority of people, but I think it's an alarming percentage of people. And I think what we're
seeing with the opioid epidemic, with substance abuse disorder that's running rampant in our society is a way of coping with feeling like you don't matter.
So if you feel like you don't matter, how do you fix that?
So it was funny.
I was doing a presentation for a major corporation that I won't name.
And a 30-year-old raised their hand and said,
you know, some days I really don't feel like I matter.
Some days I really don't.
And is there a mantra that I could say to myself?
And I said, I have something better than a mantra. And say to the man or the woman who serves you that delicious warm lunch that brings a smile on your face and thank them for always making your day a little brighter.
So the way to unlock our mattering is by unlocking it in others.
The more we can unlock mattering, even just small talk at the deli or thanking someone sincerely for doing something
for you. That is how we build up our own sense of mattering. It's one way.
That's an interesting way of, because I wouldn't think that would be a way, but anytime you have
one of those conversations, you always feel pretty good. You always feel like when you tell
somebody how grateful you are for what they do, that feels good to you. Exactly. It's a, you know,
they call gratitude a social glue, what binds people together. So when you feel appreciated,
the person, you know, even let's call it a colleague.
Let's not say it's a stranger.
Let's say it's someone in your workplace.
Really takes time to appreciate something that you've done and say it out loud.
What does that do?
It binds you to them.
It helps you notice that they are potentially a good relationship partner, somebody that may be a
relationship, a friendship that you want to nurture. And then it binds you to them. The
find-bind-remind theory is what I'm talking about, which is something researchers who study gratitude
have found with couples and with long-term friendships, that expressions of gratitude can actually act like a booster shot,
reminding you of the value of that relationship and bonding you to them.
That gratitude plays an evolutionary role in making our social connection strong.
So I guess, and you kind of questioned where I was coming from early on. And I think what I was thinking was more when I saw the title, this overachievement culture, and the solution is to lower your sights.
Don't try so hard.
You're just ruining your life.
And settle for less.
And that's not your message.
No, my message is the opposite.
My message is be ambitious for more.
Be ambitious for more than just a narrow definition of success.
What does it mean to you to live a successful life?
And what a successful life looks like to me is having a successful marriage, having a successful, strong relationship
with my kids, being a friend that people know they can depend on, enjoying hobbies, having time
for joy in my life, having enough time to rest. So what I'm saying is not to be not ambitious, but to be ambitious for more than just being a cog in the machine.
Well, it's a great message.
And I think one a lot of us can take to heart, those of us who perhaps have put too much emphasis on achievement in our life.
And maybe there's a different way.
I've been speaking with Jennifer Wallace.
She is a journalist and social commentator.
She's a frequent contributor to the Wall Street Journal
and the Washington Post.
And she is author of a book called Never Enough,
When Achievement Culture Becomes Toxic
and What We Can Do About It.
There's a link to that book at Amazon in the show notes.
Appreciate you coming on.
Thanks, Jennifer.
Thank you so much.
Since I host a podcast, Appreciate you coming on. Thanks, he had a fascinating conversation with a British woman who was recruited and
radicalized by ISIS and went to prison for three years. She now works to raise awareness
on this issue. It's a great conversation. And he spoke with Dr. Sarah Hill about how
taking birth control not only prevents pregnancy,
it can influence a woman's partner preferences, career choices, and overall behavior due to the hormonal changes it causes.

looking to hear new ideas and perspectives.
So I want to tell you about a podcast that is full
of new ideas and perspectives, and one I've started listening to called Intelligence Squared.
It's the podcast where great minds meet. Listen in for some great talks on science, tech, politics,
creativity, wellness, and a lot more. A couple of recent examples, Mustafa Suleiman, the CEO of Microsoft AI,
discussing the future of technology.
That's pretty cool.
And writer, podcaster, and filmmaker John Ronson
discussing the rise of conspiracies and culture wars.
Intelligence Squared is the kind of podcast
that gets you thinking a little more openly
about the important conversations going on today.
Being curious, you're probably just the type of person Intelligence Squared is meant for.

There is something awe-inspiring about the ocean.
Just looking at it can give you an amazing sense of wonder.
The oceans cover so much of our planet,
and yet many of us know very little about what goes on beneath the surface,
or even on top of the surface.
And many of us don't really understand what the oceans do.
Here to take us on a fascinating journey of the world's oceans is Helen Chersky.
Helen is a physicist and oceanographer at University College London's Department of Mechanical Engineering,
and she is author of a book called The Blue Machine, How the Oceans Work.
Hi, Helen. Welcome to Something You Should Know.
Thanks for having me on.
So I have always
loved the ocean. I've lived near the ocean. The ocean, there's something about it that just does
it for me. But what is it you find so fascinating about the ocean? It's that it's so many different
things. The way you see the ocean depends on your perspective at that time. And it's kind of the
same as, you know, we all understand that a human being can be many different things, right?
Someone can be a poet and a great badminton player and also a skeleton that's got, you know,
some lungs and kidneys hanging off it. And there's all these different ways of looking at what a
human being is. And in the same way, there's lots of different ways of looking at what the ocean is.
And I think the great shame is that our society really only sees one or perhaps two of those things.
And there's all this richness behind it.
Yeah, well, of course, that richness is all underwater.
So it's kind of hard to see unless you really make an effort to go look.
And I think that's why we're so mystified by it, because it isn't easy to see.
No, it isn't. Of course, we're land mammals and,
you know, the ocean is far away from many of us and it's quite hard to get out into the middle
of the ocean, all of those things. But really, the great tragedy of the ocean, I mean, all of that is
also true for the sky and for the moon and, you know, for the stars. The great tragedy of the
ocean from a human point of view is that you can't see into it, that light doesn't travel very far. Because just imagine if you could really see into the ocean. You know, we think that
water is transparent to light because when you turn on the tap, you know, what comes out is
colourless, even though actually we all teach our children to draw, you know, with blue crayons,
to draw water with blue crayons, which is just crazy. If there's enough water altogether, it
does look blue. But we think of water as something that light travels through, but actually it doesn't.
It'll go a couple of hundred meters on a good day. And so it stops us, the ocean hides itself from us.
And that's the thing that, you know, we're such visual creatures that because we can't look into
it in the same way that we can look into the sky. We sort of think it isn't there. And as you
say, that makes it harder to appreciate. But it does mean that once you start to be able to look,
you know, as technology gets better, as we get better at telling these stories,
there's a lot to see there.
Can you give me just some of the ABCs of oceans? Like, you know, how many are there? How much of
the earth does it cover? Just some of the basic facts and figures
about the ocean as it relates to us. Well, I guess the statistic that most people are familiar with
is that the ocean covers about 70% of Earth's surface. The thing that, the statistic, interestingly,
I think most people are less familiar with is that there's only one ocean. That's it. There's one.
Because it's all connected. And you can see it like this. There's
a type of map known as the Spillhouse Projection because the guy who came up with it was called
Athelstan Spillhouse. And, you know, so every two dimensional map is a version of a three,
you know, you take a three dimensional sphere and this spherical surface and you kind of try and
flatten it out somehow so you can put it on a piece of paper and he said this very profound thing he said that in order to see the land we always cut the ocean
so in order to see the ocean we must cut the land and when you draw the map like that when you unwrap
earth so that you cut the land instead of the ocean then you can see it's one big global ocean
on average it's just a little bit under four kilometers deep and
I guess one other perhaps statistic about it is that just under half of all photosynthesis on
earth happens in the ocean so you know we think on land we think about trees, plants, all those
green things harvesting sunlight and turning it into a form that other you know other life can
can eat basically like, like us.
And just under half of all of that process for Earth happens in the ocean,
even though we can't see plants and trees and that sort of thing in most of the ocean.
So, yeah, it's an important place.
There's lots going on there.
Well, you say it's all one ocean, but I remember it wasn't that long ago I saw that picture,
or maybe it was a video, of where the Atlantic, I think it's the Atlantic and the Pacific Ocean meet and the waters don't mingle, that you can see the line between one and the other.
So how are they all one if they don't mingle?
So the area you're talking about, and I think you're talking about the area of South Africa, that's the most most famous uh place where you see that um you know fish can just swim from one side to the other it's clearly connected but the water doesn't have time to mix up um that whatever's generating the
distinctiveness is kind of generating distinctiveness faster than the mixing can even it out
but you say you say fish could swim between the two things, they can go and do they?
Yeah, that's right. So and actually, because of this distinctive anatomy, you know, so to us,
it just looks like water and more water and other water. But if you're a fish, especially if you're
a predator that can swim long distances to find food, the ocean to you has structure in the same
way that we look at land
and we see hills and forests and streams, you know, we see different types of environment.
If you're underwater and you're a predator, you can effectively distinguish different types of
environment. So for example, the Gulf Stream. So the Gulf Stream is the big fast warm current that
comes up the side of North America in the Atlantic and then turns across and comes out towards us in Europe.
And it's generally drawn on a map as a kind of smooth line kind of curving around.
But actually, if you look at what it's really doing,
it's much more interesting than that,
because this river of water within other water
is sort of wobbling and meandering as it goes.
And sometimes as those wobbles grow, they get big enough.
So imagine a kind of a stream going along that starts to generate a loop and the loop gets bigger and bigger until eventually a whole part of that loop can kind of break away and it just spins by itself.
And so the Gulf Stream is doing that all the time.
And it's kind of budding these spinning islands of water that we call mesoscale eddies.
And they can be 50 to 100 kilometers across.
They can last for several months, up to two years.
And that little spinning island, either of warm water within cold water
or a spinning island of cold water within warm water,
the Gulf Stream kind of buds these off,
and then they sort of drift off either north or south.
And they've got quite distinctive ecosystems.
And so, for example, bluefin tuna will go looking for those eddies because they know
that they're good places to hunt. And the yellowfin and big-eyed tuna, they'll go looking for the cold
ones. And the bluefin tuna go looking for the warm ones. And the sharks are often found at the bottom
of the warm ones. And the swordfish hang around outside. So absolutely, they can swim across the
ocean because they know that these features are going to be there.
They know that it'll have the thing they want to hunt.
And so they can swim into them.
And once they've found one, they'll kind of stay with it
and, you know, scoff themselves silly, fill themselves with food.
And then if it starts to dissipate or to mix in with the rest of the ocean,
they'll just go and find another one.
What makes the ocean salty?
So it's quite a profound question.
It was first, Aristotle is the first person we have a record of asking that question.
And he came to the conclusion, you know, before the age of what we now recognize as science and experimentation.
He thought that the sea was salty because when sunlight hit it, it became salty.
And it wasn't until the 1600s when a guy called Robert Boyle, who was very much into experiments,
actually left some water out in the sunshine to see if it would go salty.
And it didn't. It just started to stink. So that was that idea out the door.
And there is a lot of salt in the ocean and where it comes from a mixture of places. So what we think of salt as being a solid because, you know, that's what you put on your chips or whatever, your fries.
But actually only what salt really is, is it's a mixture of different components that all dissolved in the water.
So you might have chloride and sodium and magnesium and iodide, all these kind of components.
But it's only when you take the water away that they join up to form a solid salt. So salt is actually lots of different things that are all mixed in
to seawater. And the mixture of them is the same everywhere, which is quite interesting. But it's
just because they've had so long to mix up. And so those components came from different places.
But there were two major sources. One of them was that on the early Earth,
there were huge amounts of acid rain, because way back then the environment was much more harsh,
the rain was slightly acidic. And as it ran over rocks, it dissolved some minerals from the rocks
like sodium. So that's where the sodium comes from. And of course, the rivers then ran down
into the sea and the sea gradually got more and more sodium. And then the other place you get ions from
is from underwater volcanoes,
which are belching things out from underneath the earth.
And that's where the chloride came from.
But once they're all in the ocean,
there's no way for them to get out.
So over geological time,
they've kind of accumulated in the ocean.
And now there's a kind of balance between salt that goes,
the same processes adding little bits more salt to the ocean and the processes which are kind of putting salt high and dry on land.
So, you know, in Utah, you get those salt flats.
Well, that's salt that used to be in an ocean and now it's dry on land.
So it's not in the ocean anymore.
But there is a huge amount of salt in the ocean.
If you take a household bath and you want to make it as salty as the ocean, you have to put a whole bucket full of salt in it. It's a lot of salt.
The temperature of the ocean is regulated by what?
Temperature is really important in the ocean because it's, water is a really good way of
storing heat. And we know this because if we try and, you know, if we heat up some water
in a pot on the stove or in a kettle, it takes an enormous amount of energy to do it. You have to
put a lot of energy in to warm up water by even a little bit. So that means that if you've got
some water, you can add lots of energy to it. You can effectively store the energy there,
but you've only heated up the water a little bit.
So the ocean is an enormous store of heat energy, and it comes from the sun, almost all of it. You
know, there's tiny contributions from geothermal energy underneath, but they are absolutely
minuscule. So the ocean's heated from above, and because of the way the ocean engine turns,
it turns out that the bottom of the ocean
is filled from the poles
and that the poles is obviously much colder water.
So the water that flows,
that fills up the bottom of the ocean
from different places on the world,
that's cold water.
So at depth, it can be maybe four degrees Celsius
while at the surface
where it's all being heated by the sunlight,
in the tropics, it could be 30 degrees Celsius. So you get this temperature structure which being heated by the sunlight in the tropics it could be 30
degrees Celsius so you get this temperature structure which is part of the anatomy of the
ocean and and one of the things the ocean does together with the atmosphere is move heat overall
to move heat from the equator towards the poles helping to drive the weather and of course that
influences what happens on land so it sounds you, the sort of things that a child might know about the ocean are that it's warm or cold, it's salty and it's wet. And those are quite fundamental things that determine the character of the ocean that I can see,
and I come back a week later and do the same thing,
am I looking at the same water,
or is this all new water that's moving around,
and maybe this was in Japan three weeks ago because everything's moving, or is it pretty stationary?
It's almost certainly moved somewhere.
It does depend a bit on where you are.
Yeah, that water's been on a journey
and you don't always know where it's come from.
These days, actually, we have quite clever computer models
which we can sort of run backwards.
You know, if we say if we're here,
where do we think that water came from?
So it will have come from somewhere else
and it will have mixed in with water
from lots of different places, actually.
So as the ocean engine turns, there is a very slow mixing.
So, you know, over here, if I was to dip a toe in the water
off the coast of Scotland, for example,
I would be getting some water from over on the American side of the Atlantic
that's travelled across with Gulf Stream.
I would probably be getting some water that's come down from the
Arctic. There might be some water that has perhaps it got rained onto land and it went into the
Baltic and it's come out into the North Sea. So, you know, if you were to trace the distant origins,
all water has probably been everywhere. But the interesting thing is that actually some of the
water, if you're in some places in the world where you get an upwelling from the deep, the water that you're seeing might not just have come from another
country, but it might have been down in the deep ocean for so long that it hasn't seen sunlight for
a few hundred years. So you're also kind of going back in time, you know, the last time it was
connected to the atmosphere, connected to the rest of the planet could have been a long time ago. So the water is also coming to you from different times in time
as well as different places in space.
What about the ocean do you think people maybe don't know
that would be fascinating because it either affects them,
it affects us, or it happens and we don't see it,
or just something that's really rather amazing that is under the
radar? If I had to pick one thing off the top of my head, you know, I would say how important sound
is in the ocean. We have this idea that the ocean is kind of silent, partly because of films and
partly because of one specific film, The Silent World that Jack Kustone made back in 1956.
And we don't prioritize sound very much on land.
We're visual creatures. We look for things. We look at things that are a long way away. And we
kind of know that we usually can't hear things that are a very long way away. But in the ocean,
it's exactly the other way around. Light doesn't travel very far. Light is not a long distance
messenger, but sound is absolutely critical. So I think in terms of things that we don't think about when it comes to the ocean,
the importance of sound and the number of different sounds there are.
So on a coral reef, for example, or the fish and the crustaceans, whatever's down there,
they're basically chattering away.
They're grunting and squeaking and making all kinds of noises.
They're talking to each other.
They're paying attention to what's around them because they can hear what's around them.
And it's been shown, a scientist called Steve Simpson at the University of Exeter recently did a study showing that if you've got a dead coral reef, you know, one that's been bleached.
And so there's not very much living there. If you play the sounds of a live coral reef in that place, then the larvae of fish that are kind of floating around in the water are more likely to settle there.
So coral larvae, for example, or small things that need an anchor point, you know, barnacles and so on,
they're more likely to settle in a place that's got the right sound.
So when you see like a hurricane, a big weather system,
and the water looks all chopped up and big, huge waves out in
the middle of the ocean, ships being thrown around. But you get the sense that just below
the surface, things are quieter. That if you go down not too far, things kind of remain the same.
Is that true? And maybe that's because when you swim in the ocean and you go down a few feet,
things seem pretty calm versus the waves on the top of the water. Is that true in the ocean?
No. But the reason it's not true, I mean, the waves are pretty turbulent. And that's part of
what I study in my academic job. But actually, it's to do with how we look at the world. So we
have eyes and senses that can see waves, but they can't tell the difference between different types
of water, you know. But what we can't see is all the other character of the water. So we can't
directly detect the amount of living things that are in the water. And most living things in the
ocean are really, really tiny.
In land, we tend to think of, you know, that kind of life as being trees, big things that we can see.
But in the ocean, it's far too small to see. And I estimate if you look at those numbers,
I estimate that just over 60% of all ocean life is too small for us to see with the naked eye.
So we can't see what's happening with the life for a start.
And even then, there's small things in the water
that we technically could see if we were looking for them,
but they tend not to come out during daytime.
So for example, the biggest migration on Earth
happens at dusk in the ocean
where lots and lots of very tiny creatures
that have been hiding down in the darkness,
as the sun goes down, they rise up in the water column and come up to the surface to hunt and then when the
sun you know when the sun rises again they go they sink back down so we tend not to see those
because we tend not to be swimming in the dark um so so it's not that there aren't things happening
it's just that our senses are biased. So we don't see them
in the we're not aware of them in the same way that, you know, smaller creatures or creatures
that live in the ocean that have to, you know, navigate through these conditions would be able
to tell. So there is, it might be calmer in the sense that, you know, it's not like a washing
machine, you know, you've not got that kind of turbulence that's smashing everything about.
But it is definitely the case that there are lots of things happening and there is a huge
amount of character, but we can't see it directly. Are there any misconceptions, things people say
about the ocean that drive you crazy that you know aren't true or anything like that?
So I've got a right bee in my bonnet about this comparison between the moon. People sometimes, there's this statement people say that we know more about the surface of
the moon than we do about deep ocean. It drives me mad. It's wrong. It's wrong in every possible
way. And I'll spare you the full rant. But the basic reason it's wrong is that there is so much
more to know about the ocean. It's a much richer environment. And the moon is a dead rock that
hasn't changed for 2 billion years. And you know, it's perfectly nice. I have nothing against the
moon. But it's a static environment that kind of, you know, it's not doing anything. And it's
relatively limited in what's on offer there. Whereas the ocean is enormously rich. It's got
all these different types of life. It's got all these different types of chemistry. It's moving. It's changing with the seasons. It's changing with the time of day. It's doing things all the time. So it's a far richer environment. And that statement about comparing the moon to the deep ocean drives me nuts because it implies that the deep ocean is only as interesting as the moon. and it's much, much better. There are lots of interesting things that we don't know about the ocean. You know, we've never seen giant squid or colossal
squid mate, for example. We don't know where they do it or how they do it. There's plenty of, you
know, we don't really know what sea turtles do when they're not nesting or feeding because they're
off on the beaches. Those are just two biological things. There are lots of physical things as well.
So just exactly how water is moving along and how it really mixes in the deep ocean. There are lots of physical things as well. So just exactly how water is moving along and how
it really mixes in the deep ocean. There's lots of questions there. But we also do know a lot about
the ocean. We're just not very good at talking about it. So we absolutely do have a very good
picture of this engine and how it works. But I do think that we need to get away from this idea that
the dominant thing we know about the ocean is that it's mysterious.
You know, if you want mystery, look into space, it's empty. Have your mysteries out there. The
ocean is doing so many interesting and beautiful things. We need to look at that for what it really
is, to appreciate that for what it really is, rather than just sort of dismissing it as a mystery.
Well, okay, if you say so. But one of the things I find so interesting about the
ocean is the mystery of so much that I have no idea what's going on down there. And that somehow
fascinates me. I've been speaking with Helen Chersky. She's a physicist and oceanographer
at University College London's Department of Mechanical Engineering. And she's author of a
book called The Blue Machine, How the Ocean Works.
And there's a link to that book at Amazon in the show notes.
Thanks for this little tour through the ocean.
Appreciate it, Helen.
No problem.
Thanks for inviting me on.
Men need praise.
That's according to Dr. David Clark, author of a book called The Total Marriage Makeover.
He says the more a woman praises her man, the better the relationship will be.
But, he says, most women aren't very good at it.
The tendency is to focus on all the things men are not doing or are doing poorly.
And maybe all those criticisms are valid, but they totally demotivate a man.
So, instead of criticizing a man for spending too much time at work,
praise him for the time he does spend with you and the kids.
When women criticize men for what they're not doing,
it breeds more of the same.
Praise, on the other hand, is such a deep need for men
that they will go to great lengths
to get more of it, including doing what you want him to do. Try it. Dr. Clark says it always works.
