On this episode of Our American Stories, did you know "radar" is actually an acronym? It stands for RAdio, Detection, And Ranging—created in 1940 by our Navy. Tim Harford, author of the bestselling book 50 Inventions That Shaped the Modern Economy, shares the stories of three inventions that changed the way we live today.

Our next storyteller is Tim Harford, an economist and best
(00:30):
selling author of Fifty Things That Shape the Modern Economy.
Here he is to tell the story about a few
of those.
Speaker 2 (00:37):
The iPhone has a very interesting lesson for us. I think,
I mean, I don't need to tell you how it
changed the economy, but I think where they came from
is a very interesting lesson. So this argument is made
by an economist called Marianna Matzakato, and she says, look
what is in an iPhone. You've got a touch screen,
You've got the solid state hard drive, you've got the
(00:58):
computer chips, got algorithms, particularly algorithms that convert digital to
analog and analog to digital. And you've got GPS, you've
got access to the Internet. You've got the cell phone structure.
You've got all of that going on. Okay, these are
the building blocks that Steve Jobs put together to make
this amazing invention. So who invented the building blocks, and
(01:21):
when you look at the history of it, very often
they came from governments, very often the American military, although
not always. For example, the touchgreen is a British government invention.
It was invented at the Royal Radar Establishment. So you
look at all these different inventions and they all have
these government or military origins, which is very striking because
(01:43):
a lot of people, myself included, like to sing the
praises of private sector innovation, the power of the entrepreneur,
the creativity of the free market. I'm all for that,
I believe in that, but we also have to look
at the fact, and in this particular killer fact, a
lot of these building blocks came from governments. They were
(02:05):
put together by brilliant entrepreneurs Steve Jobs, but he would
not have had the raw material to work with. He
would just have been making a clever toy if he
hadn't had these different inventions. Even Siri was designed originally
for fighter pilots and eventually became repurposed for smartphones. So
it's a lesson about how sometimes the origins of these
(02:26):
amazing inventions that shape the world around us, and not
always the origins we expect they weren't always produced by
the people who get most of the credit radar. Originally,
the idea was a couple of British scientists during the
Second World War. We're going to create a death ray.
We're going to use electromagnetic radiation to create this beam
(02:49):
that will heat eight pints of liquid i EE blood
above whatever one hundred and five degrees fahrenheit, enough to
make a pilot of a plane pass out as a
knock planes out of the sky using our death rate.
And the two scientists discussing this idea very quickly realized
there's no way. We don't have the power, we don't
have the range. It can't be done. But we could
(03:11):
use electromagnetic waves to bounce off planes, and we could
interrogate the signals that come back, and we could use
that to track incoming planes. And this is a hugely
important development in the Second World War because it meant
for Britain. As these German bombers came over high and fast,
(03:31):
attacking British cities, we could see them coming and we
could scramble a response and we could actually intercept them.
Change the course of the Second World War. And then
various developments that made radars more powerful and more compact.
You could put them in submarines, you could put them
in airplanes, you could use them all over the battlefield.
But on top of that, once you've got that military technology,
(03:54):
you've got a technology that makes civilian airspace a lot safer.
And initially, those early civilian flights, it was just a
case of well, you plot your course on the map,
and you fly from one airport to another and keep
away from clouds and hopefully you un crash into another plane.
And there was a tragic crash over the Grand Canyon.
Two planes, both trying to give their passengers a view
(04:16):
over the Grand Canyon. They hit each other, terrible loss
of life. And at that point people started saying, you
know what, we've got this technology. We could use it
to track where all the planes are, to run a
kind of air traffic control system, and to keep everyone safe.
And ever since then, air travel has been getting safer
and safer and safer, famously safe, no matter how dangerous
(04:37):
it may seem when you're up there in one of
those thin tubes. And it is partly because of radar.
Lots of people said, you have to do the washing
machine because the washing machine liberated housewives, women who could
be going out to work for money, getting economic independence,
(04:59):
getting experienced the workplace, fully contributing to society, and there
they are, they're stuck at home doing the laundry. I
wanted to write that story. I thought it was a
great story, but when I looked at the actual data,
I found washing machines did not save women any time.
What happened was, instead of doing one wash a month,
you'd do one wash a day, and we all looked
(05:22):
a lot cleaner and smelled a lot cleaner, But it
didn't actually save the housewives. The ones having to take
responsibility for this didn't save them any time. The TV dinner,
on the other hand, did, and by TV dinner, I
mean not just the thing in a tray that you
would warm up and sit there with it in your lap,
but all of the other technologies by which food was industrialized.
(05:46):
So the idea that rather than plucking your own chicken,
the chickens pre plucked, and maybe it's pre seasoned and
pre stuffed, and actually, if you go to a deli,
maybe it's also pre cooked. The other whole thing's ready
to eat. About potato chips to prepare fresh potato chips,
to finally slice all the potatoes and to heat up
the hot oil and all the mess and the risk
(06:09):
of that involves, and to fry them huge amount of
time and effort. But you can buy potato chips in
a bag, take seconds, you can eat them anywhere. Pre
Chopped salads you don't need to chop your own sale,
you don't need to wash your own lettuce, The salads
there in a bag. All of these different technologies, frozen meals,
take away pizza, the whole lot. All of this save
(06:29):
women an enormous amount of time. So with all of
these inventions, we should be asking ourselves what can we
do to enjoy the benefits without the costs. Technologies never
just solve problems, They always create some problems as well,
and so there's always an opportunity for us to do better.
Speaker 1 (06:49):
And a terrific job on the production editing and storytelling
by our own Greg Hengler, and a special thanks to
Tim Harford. He's the author of Fifty Things That Shape
the Modern Economy and the stories today are on the iPhone,
radar and TV dinners And reminded, of course of that
nineteen fifty six Grand Canyon mid air collision, which I'd
(07:11):
seen pictures of as a kid and just did not
know that this was This was the beginning the catalysts
that prompted modern radar. The story of the iPhone Radar
