@Akhanyatin can we see your replication of eratosthenes

How do I drink milk

With a cup

@Citizen Z You need to do the experiment with more than two wells.

@Citizen Z please, don't insult me, there are no measurements in there, no angle values, no nothing.

@SAM101907 i just showed you 4 wells

@Akhanyatin please show me your experiment with 4 wells

That you personally did and you vouche for the data

Eratosthenes is the dumbest globe proof ever @Akhanyatin

2000 year old myth

@Citizen Z https://www.youtube.com/watch?v=V03eF0bcYno

You show me an accurate flat map of the entire earth

And you showed 0 wells, there are no angles there

No geographical coordinates

You could have shown it on a pyramidal earth, it would have been as valid.

I believe they are currently doing a really big one

Yeah hopefully the add defraction refraction for each spot

why would they add that for each spot

do you mean diffraction and refraction as separate additions

or diffraction refraction as its own term

Diffraction is: the process by which a beam of light or other system of waves is spread out as a result of passing through a narrow aperture or across an edge, typically accompanied by interference between the wave forms produced.

Refraction is: the fact or phenomenon of light, radio waves, etc. being deflected in passing obliquely through the interface between one medium and another or through a medium of varying density.

so you want them to add how the light spreads out through the wells and how it changes when passing through the wells?

Lol

well what do you want added

well refraction would mess up the well experiment

diffraction would too tbh as light enters the well

so yeah they should add defraction and refraction for each spot

but it isn't going through a medium/going through a narrow hole?

@mineyful it's going across an edge when it passes into the well

and it would directly affect the angle you're trying to measure

and on its way there, the atmosphere of course

going across an edge isn't a new medium and going through the atmosphere isn't going to get you divergent rays

also directly affecting the angle is the exact thing we're testing

that edge is supposed to make the angle we're testing

the atmosphere totally diverges rays

really?

and directly affecting the angle is bad bc it's by unpredictable refraction

we have a formula for that

yes, any time the rays start unparallel
