What was NEVER EXPLAINED in that episode was HOW did they communicate so they knew the lengths of the shadows on the same day, the same time

The pillar directly under the sun has no shadow at noon, the one to the north does. Travel time won't change the angles. Then math!...

The history of scientific discovery is easily as interesting as scientific knowledge itself. Ridiculous how some things were found out.
opticsnake
This assumes your light source is sufficiently far enough away that the difference in angle from the light source to the two sources is(1/?)
twfeline
They tried to fire an arrow at it, but didn't get close, so they assumed the Sun was a long way away.
opticsnake
(sorry..two objects) small enough to be negligible. Flat earthers explain things like this away by saying that the sun is much smaller (2/?)
opticsnake
and closer than we know it to be. Example: on a flat table with a table lamp place two of the same objects, one close to the base of (3/?)
opticsnake
the lamp and another about 12 inches out from it. The one close to the base has a shorter shadow. Based on what he just said, the table(4/?)

would have to be curved. I don't believe the earth is flat but this explanation requires the base assumption about the sun being far away.

not "prove" the earth is round (while it does provide strong evidence.) The same phenomenon is observed by using a smaller light source

which is much closer to the object. The source would be more above one obelisk and to the side of the other, casting the same shadow pattern

How did he know how long the shadows where at the same time? Didn't they measure time based on the height of the sun back then?.
radieon
They measured the distance between the two points, and measured the shortest shadow (noon)
Kovalentus
Yep, exactly. Measure the min length of the shadows and you'll have the lengths for midday for both places. Different lengths = round earth
Nottherealslimshadyjusthisbodydouble
I assume he measured the length of one shadow at set times for a few days, then did the same for the other and compared. Scientific method
BendystrawCrumblesnatch
Midday is when shadows are shortest, i.e. highest in sky, which allows measurement to be synchronised.
scotskies
Highest point of the sun over three days anywhere you can see it is easy. https://en.wikipedia.org/wiki/History_of_navigation
technollama
Eratosthenes read a report that during midday of June 21st a post in Syene would not produce a shadow. He measured in Alexandria day/time.

He had lived in both towns. He also sent a slave to count the steps between each one.
Lissyb
Step 1: Place sun dial at both locations; Step 2: Record length at same time on dial at both places; Step 3: Compare
LuciusAelius
iirc, he measured the shadow of Alexandria at noon on midsummer one year, and measured the shadow of Syene the next.
beardyfaceguy
That's what I remember too. He waited a year to get the second measurement. But I thought it was the summer solstice.
Nottherealslimshadyjusthisbodydouble
Actually now I think of it what I said makes no sense without a way of confirming the time at the other place
hi5560
He had a second person at the other place measure it at the same time.
UsChickens
Seriously? You can't figure out how that was done? About those free public schools...
FlowbeeRevival
He had an intern pace out the distance and measure the minimum shadow length (occurs at midday)
hitshappens
You have 2 people in 2 places set to record on the same day. You take the shadow every few minutes from sun up to sun down and compare both
[deleted]
[deleted]
hitshappens
Which serves as evidence that the world is round. Also, you can compare peak heights at both locations
CantoCement
then you still need a way to measure those minutes though.
caedescorvidus
they had water clocks at the time as well as candle or sand clocks
CantoCement
right. so i guess you could have had two of those clocks start at the same time and then transport one of them to the other city :D
viila
You don't need to measure the time. You just do the measurement every few moments and then pick the shortest length as your answer.
viila
You don't need to know when exactly it was, just what it was. The interval doesn't matter as long as it's often enough that you can spot it.
Cereaza
Mmmm. Love it.

Makes sense. Just because he's credited with doing it, doesn't mean he didn't have a few interns to help out.

That was my first thought too. I also wonder how they could know the exact distance between the two places.

Typically they used walkers with practiced steady step lengths who counted how many steps it took to walk the distance.
moodytravesty
nobody said the answer back then was as accurate as is it today, just that it was the only explanation for what was seen
Nottherealslimshadyjusthisbodydouble

Sure, but you can't travel that far in a straight line.
Nottherealslimshadyjusthisbodydouble

GreatWhiteNorthEh
Which is the right question to be asking. Shows a desire to understand, not just to memorize to sound smart at parties.
moodytravesty
the 2 locations are N/S of each other, "time" is measured as the sun moves E-to-W. so they can tell when the sun is at noon at both cities
ArcipluvianCosmicGallows
I always wondered that! Thank you!
ShitsNGiggelz
Me too!
moodytravesty
they cities don't even need to be "noon" at the exact same time. the point is that at "noon" the shadows differ, which means the sun is 1/
moodytravesty
at different angles to the two cities at noon, which means the sun canNOT be directly overhead to both of them. 2/
animatic
By the same token, there were probably ways to check the angle and measure time with hourglasses, etc.
animatic
Also, what if either obelisk were not straight?
moodytravesty
it would fall over
JodyHighroller
they are.
JustEngineeringPuns
But couldn't it also mean that the earth is flat and the sun is really close so that viewing it from a different city would have a (1/2)
Curiousone545
No, because then the temperature would be dependent on the sun's position to earth. Which is easy to demonstrate w/thermometer & logic.
moodytravesty
if you take measurements of the same shadow at different times, you can estimate the sun's distance away
JustEngineeringPuns
substantial impact on its angle?

Couldn't it also have just meant that Apollo was doing his zig-zag thing when he sees a fine-ass shephardess?
