Speaker 1 (00:00):
Learn UK English, but Vodkas morning. Rachel.
Speaker 2 (00:12):
Hey, Neil, how's it going?
Speaker 1 (00:14):
Not too shabby? Thanks? And you how's life in London?
Speaker 2 (00:17):
Can't complain? It's all pretty standard here is it?
Speaker 1 (00:20):
Warmer?
Speaker 2 (00:20):
A bit nippy, bit of a scorcher. We're right in
the midst of summer. Sometimes there's a sudden downpour and
it cools down, but it hasn't dipped below eighteen degrees celsius.
Speaker 1 (00:30):
Blimey, Rachel.
Speaker 2 (00:31):
But it can shoot up to thirty five degrees celsius.
So it's quite the swing.
Speaker 1 (00:36):
I can imagine. So, Rachel, you're hosting the show today,
then that's right.
Speaker 2 (00:40):
Today I'll share the story of how a mathematician invented
the search formula used by Google.
Speaker 1 (00:46):
Brilliant. Can't wait to hear it.
Speaker 2 (00:47):
It's a fascinating tale, Neil. Did you know that every
time you run a simple Google search, you're employing logic
principles conceived over one hundred fifty years ago.
Speaker 1 (00:57):
Over one hundred fifty years ago.
Speaker 2 (00:59):
Indeed, it was the British mathematician George Bull who devised
an algebra system pivotal to programming even today. Ball lived
from eighteen fifteen to eighteen sixty four, so that's about
one hundred and fifty years back.
Speaker 1 (01:12):
That's wild. So if you want to search on Google,
you've got to bull Google so to speak. Oh, is
that why it's called Google?
Speaker 2 (01:20):
Precisely, it's a nod to Bull. In fact, on the
two hundredth anniversary of his birth, Google paid tribute with
a special doodle, which is a tweaked version of the
company's logo. They do these tributes quite often. For George
Bull's anniversary, they used an animated logo showcasing the logical
gates used in computing, all derived from Boolean functions.
Speaker 1 (01:42):
Core blimey. So he was quite the figure then.
Speaker 2 (01:44):
An absolute game changer. The name Google itself is inspired
by George Bull. Boolean algebra, as it's called, maps out
logical functions and is ubiquitous from basic video game programming
to the codes of applications and computer programs use daily.
Speaker 1 (02:01):
It's odd, Rachel. When you think of it, you reckon
it's a recent thing, say from the past twenty years
or so. Spot on, But you're talking about a revelation
from over one hundred and fifty years ago.
Speaker 2 (02:12):
Absolutely, Neil, an old discovery that's still relevant today.
Speaker 1 (02:16):
One thing I do know about computing is it's all
zeros and ones.
Speaker 2 (02:19):
Right right you are? You can't escape the Boolean operator.
The most basic logical gits in Bull's original language are
and or and not, So when you search for a
compound term online like London Bridge, there's an implied Boolean
logic using the ain in command to combine the terms Crichie.
Speaker 1 (02:39):
That's something.
Speaker 2 (02:40):
Back in the day, people would often use the and, O, R,
and not commands to filter Google results. Now technology has
advanced to automate this, but old school netizens might still
employ them.
Speaker 1 (02:52):
Rachel, I guess I'm from the modern lot then never
use those an's ores or nots.
Speaker 2 (02:56):
Do you recall neither have I? I started using the
Internet at about eighteen years ago, back in the days
of dos before Windows.
Speaker 1 (03:04):
So you're a bit of a veteran Rachel.
Speaker 2 (03:06):
Maybe in the UK, but abroad these things probably caught
on much earlier.
Speaker 1 (03:10):
It's a classic UK thing, isn't it. We always catch
on a bit late, although now things seem to be
speeding up. But back in the day it was all
about the tea and crumpets.
Speaker 2 (03:19):
Absolutely, globalization means we can now get our hands on
the latest and greatest from around the world at lightning speed.
It's quite something how swiftly information travels these days too.
Speaker 1 (03:31):
Right, so are you into tech? Rachel?
Speaker 2 (03:33):
Sure? Am. It's pretty much part and parcel of modern life,
isn't it.
Speaker 1 (03:37):
And leaving a lasting mark on humanity is quite the aspiration.
Speaker 2 (03:41):
Indeed, everyone wants to make their mark, leave a legacy,
make sure they're not forgotten.
Speaker 1 (03:46):
True that it's interesting to note, Rachel, that the eighteen
hundreds were an era marked by enlightenment, loads of discoveries happening.
So true, it was like the golden age of invention,
most principles foundational to modern science. It's hail from that time.
Speaker 2 (04:01):
It was a defining period, no doubt.
Speaker 1 (04:02):
Do you know any boffins, Rachel.
Speaker 2 (04:06):
The only brainiac I know is my brother, a physicist. Ah.
Speaker 1 (04:09):
That probably inspired your childhood dream of being a mad scientist,
didn't it?
Speaker 2 (04:12):
Maybe, though I reckon it was more due to those
comics with mad scientist.
Speaker 1 (04:16):
Characters, ha ha. Fair enough.
Speaker 2 (04:18):
It's astonishing how an idea from so long ago can
still have such a profound impact on our daily lives
and modern tech.
Speaker 1 (04:25):
Absolutely, no of any UK tech contributions, Rachel.
Speaker 2 (04:29):
The UK has been quite influential in tech over the years.
For instance, we have Tim berners Lee, the British scientist
who invented the World Wide Web. There's also Alan Turing,
widely considered the father of theoretical computer science and artificial intelligence.
Speaker 1 (04:45):
Gosh, that's impressive. Had no clue the UK had such
a rich history in tech and innovation.
Speaker 2 (04:49):
Oh definitely. The UK has left its mark globally in
myriad ways, and tech is just one facet.
Speaker 1 (04:56):
Cheers Rachel for sharing all this.
Speaker 2 (04:58):
It's been enlightening, no worries always fund having these chats
with you.
