00:13

New kinds of sales and ships were being developed all

00:15

over the world and the scientific study of the stars

00:18

had led to new navigational technologies Let's check out a

00:22

few of the innovations that kept our ancestors from getting

00:26

totally lost at sea or from the worst fate of

00:29

all according to dad's everywhere having to stop and ask

00:32

for directions well one of the most popular medieval navigational

00:36

tools was called come out no it wasn't a camel

00:40

with a perfectly good sense of direction They were basically

00:42

simple wooden blocks with complex markings on them Those living

00:47

near the equator could use the markings and the stars

00:49

to determine their latitude Almost people gave them and enthusiastic

00:53

two thumbs up for not steering them into madagascar On

00:56

accident the leamer is freak out interrupt their beauty sleep

01:00

come owls were developed by arabs european traders almost exclusively

01:05

stuck to coastlines Arab sailors however sailed deep into the

01:09

indian ocean and down the dangerous coast of east africa

01:13

Well the kamal was an essential part of getting their

01:15

trading and conquering done without getting lost or you know

01:18

ending up on the bottom of the ocean because spoiler

01:21

01:25

they be They got no troubles Life is the bubbles

01:28

under the sea Right Well basket obama The portuguese explorer

01:32

was introduced to the come on while visiting india in

01:35

fourteen Ninety eight Well not long after europeans it after

01:39

the idea into an instrument called the crossed staff Ten

01:42

bucks says that they said it was their idea to

01:45

begin with One popular instrument for europe was the astro

01:48

lab Well for non equatorial places like medieval europe astro

01:53

lab was where it was at astro labs were circular

01:57

brass object designed to measure the angle between the horizon

02:01

and the son or any nice bright star They did

02:04

have problems though they weren't always accurate Like when our

02:07

gps tells us turn left right off of a bridge

02:11

And astra lobs were especially inaccurate on the rough seas

02:14

So great One thing worse than being on the high

02:18

seas in the storm is being completely lost while on

02:21

the high seas in the storm but hey you get

02:23

what you pay for Those things are probably way cheaper

02:26

than our gps We'll compasses back then were also a

02:29

thing The chinese had reliable magnetized compass is by one

02:33

thousand see eat but they rarely use them on ships

02:36

For some reason Go figure the venetians got more serious

02:40

about them in the thirteenth century with compasses only tell

02:44

us where north is That means we still have to

02:46

use other technology to figure out you know where the

02:49

heck we are And for those of us who weren't

02:52

in the scouts we'd also have to figure out how

02:55

to use a compass Because believe it or not they

02:58

don't tell you how we get to the nearest dairy 00:03:00.1 --> [endTime] queen in a soothing robotic voice
