Sythe Users: What Do They Know? Do They Know Things?? Lets Find Out! #3

The diagram is just to picture the effect, you don't actually need to travel to hemispheres to test it. A few hundred meters or a few kilometers should be enough to see it in action, thus allowing jim to demonstrate this idea whilst staying inside his country.

i edited to increase the distance, also, i'm telling jim to walk 10km, turn right 90 degrees, walk 10km turn right 90 degrees and walk 10km.

after this 3rd 10km he will be back to the starting point if earth is round.

if earth is flat, he would draw a square with 1 missing side as opposed to a triangle if earth is round.

so if jim does what I tell him to do and after 2 90 degrees right turns, he ends up at the starting point, he will have proven that earth isn't flat

Incorrect about the triangle but it is a method that might work never the less. How will Jim measure the arc lengths in each case and the angles?

And by this Jim knows the Coriolis effect does exist, which in turn can be used to prove the Earth is indeed round.

This doesn't make sense. Also the Coriolis effect is not strong enough to be obviously present when factors like wind are involved.

 

Does this country have a port ?
If so poor Jim can prove to his owners that the earth is not flat by the fact that ships don't just appear on the horizon, but rather "emerge from the waves"

this ^^^^

Given that the overlords know Jim's math of LxWxH for his wall is incorrect, and killed his family, Jim now know's his equation is wrong. Thus, he knows he cannot be living on a flat plane.

Same as chechen, want an answer

True, which is why I was confused when you said "it would suggest the coriolis effect is not present", as the vertical component of the Coriolis acceleration is small when compared to gravity.

Hmm. Perhaps I should study more for Jim.

Surveying equipment does not incorporate curvature because building projects have a tiny footprint compared to the curvature of the earth.

That's exactly what transits and lasers do lol...

jim doesn't need to measure the arc lenghts and the angles.

all he has to do is mark his starting point and then walk in a straight line for 10 kilometers, then from that point, he takes a 90 degrees turn right that he measures with a straight piece of wood that he places perpendicular to the direction he was coming from. this will allow him to turn 90 degrees right.

he then walks another 10 km in the direction he turned, once he's done walking that 2nd 10km, he uses the same procedure to turn 90 degrees right and continues to walk another 10km. now, because the earth is round, he will arrive at his starting point which he marked at the beginning of his journey.

if the earth was flat, he would have arrived at the fourth vertex of a square which misses an arc between the first and fourth vertex as opposed to arriving back at the first vertex of the "triangle" he formed doing these two right 90 degrees turns

As Shite is a country based on the Equator, it has the same day length each and every day right at the equator. However, if the day length (time between sunrise and sunset) was measured at the southern most point of Shite, directly at the equator, and at the northern most point, each one would be different. If the Earth was a flat plane then the day length would be the same everywhere regardless of the tilt of the plane, on a sphere the tilt of the sphere affects the day length at certain positions on the sphere making the day length change. Which assumes that the Earth does have a tilt for this experiment to work, bit of an assumption but most planets have a tilt from what has been seen, but it should be known to even shitians that days seem longer as they go away from the equator if they have any source of information.

You are fairly consistent at repeating yourself. Have you considered becoming a truck driver?

Sorry misread your original statement hence the source of confusion. I thought you were saying the melon falls directly down back into the mortar tube. Which actually is an experiment that has been done and it does sometimes happen. However as already discussed the wind and aerodynamic factors alone drown out any coriolis signal in this test making it useless as a proof.

Does this country have a port ?

This would still happen on a plane. Again to do with the way perspective works. The optical/visual real estate at the horizon line is used up more readily than the real estate above or below the line, so an object coming from a great distance will appear to have its lower part cut off until it comes closer.

That's exactly what transits and lasers do lol...

Transits and lasers measure using straight lines. Curvature has to be factored in mathematically if needed.

jim doesn't need to measure the arc lenghts and the angles.

all he has to do is mark his starting point and then walk in a straight line for 10 kilometers, then from that point, he takes a 90 degrees turn right that he measures with a straight piece of wood that he places perpendicular to the direction he was coming from. this will allow him to turn 90 degrees right.

So Jim walks up a hill and has to change course to get around some rocky outcrops... then gets exactly back on his track whilst walking down a ridge line. Then he uses wood to determine an exact 90 degree angle. I don't think this proof would please his overlords. You'll have to come up with a practical way of proving your point.

he then walks another 10 km in the direction he turned, once he's done walking that 2nd 10km, he uses the same procedure to turn 90 degrees right and continues to walk another 10km. now, because the earth is round, he will arrive at his starting point which he marked at the beginning of his journey

As I already said this part of your reasoning is incorrect. He will not walk a triangle unless he reaches the poles relative to his starting point.

As Shite is a country based on the Equator, it has the same day length each and every day right at the equator. However, if the day length (time between sunrise and sunset) was measured at the southern most point of Shite, directly at the equator, and at the northern most point, each one would be different. If the Earth was a flat plane then the day length would be the same everywhere regardless of the tilt of the plane, on a sphere the tilt of the sphere affects the day length at certain positions on the sphere making the day length change.

Incorrect. If the sun were a spot light illuminating the surface it could follow any path it wanted including one which makes a longer day in southern Shité relative to northern Shité.

Since when do triangles have 90° angles?

well, normal triangles always have had 90 degrees angle (1), they are called rectangle triangle.

This however is a spherical triangle. That is kind of the point i'm driving at, if you come back to the starting point after making only 2 turns (90°) then you formed a triangle, but that also means that the sum of all angles in this "triangle" is over 180°.

if this triangle was on a flat surface, this would be impossible as "flat" triangles can't have a sum of their angles greater than 180°. we then have no choice but to see that it is indeed a spherical triangle since the sum of its angles is > 180°

Top kek. Just needs egg on his singlet and some strong pornography in the glove box alongside the trusty ol' three sided map.

that's not fair you change the variables along the way.

what if i was to assume that jim chose a region of 'whatever-the-hell-the-name-of-his-country-is' where it was flat land and no rivers to cross or mountains to climb. Then my test would work

Ok maybe hes on that dry lake bed. Can you prove a spherical earth from there?

 

[Jay]

Jim and the overlord could sit by the seashore, even if they don't see a ship go over the horizon. The edge of the Earth would have to be just a few miles away, and there's no way that the entire, circular world would fit inside the circle that the ocean horizon seems to make.

If that doesn't work, they could look into the sky at night and spot a planet with a telescope, they look round, and all bodies of enough mass tend to be speherical by virtue of "isostatic adjustment" Why would earth be an exception?

 

[Thatnameistaken]

I'm going I am right, as I never got a response.

Incorrect method is still incorrect when repeated

well since this dry lake bed has a diameter of at least 150km ,

he could start from the center of the lake and do what I told him to do in the beginning.

After turning twice to the right with 90°*angles, he'd get back to the starting point, proving he drew a spherical triangle thus proving that earth has a spherical shape

Except he wouldn't be because turning 90 degrees twice on a sphere only takes you back to your starting point in very special circumstances.

Look try this: Go to an actual location and walk in a straight line as far as you can, count your steps. Turn 90 degrees and walk the same number of steps, then walk 90 degrees again the same number of steps. Are you where you started? Why do you think this will work?
