41 分钟Hello and welcome to another episode of No Such Thing as a Fish,
a weekly podcast coming to you from the QI offices in Covent Garden.
My name is Dan Schreiber, I'm sitting here with Alex Bell,
Andy Murray and Anna Chazinski and once again we have gathered around the microphones with our four favorite facts from the last seven days and in no particular order here we go.
Starting with you, Andy.
My fact is that scientists have developed barcodes for zebras.
They've also developed a separate and identical system for zebras.
We'll get on to how to say the name of the thing in a bit but this is a team of scientists at and what they've done is this is a particular species of zebra called the Grevy's zebra and it's the rarest of the species of zebra and they've persuaded volunteers to take 40,000 photos of different animals and the scientists have then used this software on them
because they've all got completely unique strike patterns and it combines barcode technology and facial recognition software and so you can now identify an individual animal from it.
Leven Skyro who's been on as a guest,
he has a show in Belgium and one of the games
because when you go to a supermarket in Belgium they give you a scanning gun to take around now so you can just scan
as you go along the items and then you hand the scan gun in at the end and then they tally up what you've found in your badge as well.
So he convinced the supermarket in allowing him to have him and his friends have barcodes printed up on t-shirts and they ran around the supermarket like laser quest and we're trying to scan each other's shirts and they had to collect all the kills
as it were.
Yeah, very cool game.
Well I got three zebras.
It's really,
I had no idea this is how it works but each gap and space combo is a number and so each digit is a combination of seven black and white bars so to say one in a barcode it's white,
white, black, black, white, white, black.
