Flat Earth Debate / Re: More Utterly Undeniable Proof of Flat Earth!

He presented the numerical data in the plots. I say that the accuracy displayed there can not be achieved with his equipment.

I would expect the precision of the results to be of order 5-10%, but this is just a rough guess and definitely depends on the used method.
As he wants to determine a 0.25% difference (at most), I would want an accuracy at this order of magnitude.

But please be honest with youself: Do you really think the obtained data with only 0.5% deviation can be obtained with an iphone 7 video camera and a person jumping?
I am actually curious in your honest answer InFlatEarth. If you guys want more, here is the matlab code I used to "analyze" the data:

fake = zeros(1,100);
fake(1:100) = 9.807;
fluc =  rand([2 100]);
fluc2 =  (fluc-0.5)./1000;
data = fluc2+9.807
trial = 1:1:100;
figure(1)
plot(trial,data(1,:),'b-o')
title('New York State');
xlabel('Trial Number');
ylabel('Acceleration of Gravity');
hold on
plot(trial,fake,'r');
legend('Measured Values','Average');
figure(2)
plot(trial,data(2,:),'b-o')
title('Indonesia');
xlabel('Trial Number');
ylabel('Acceleration of Gravity');
hold on
plot(trial,fake,'r');
legend('Measured Values','Average');

I apologize to the people who put effort into showing me the flaws in my "methods". I did learn about the existence of a gravimeter from you guys though. InFlatEarth, I appreciate you defending me, but your defenses don't really make any sense. I did graduate from GW but I have not been a PhD student for two years. In truth, I just graduated College and am starting my PhD at CMU this fall. In the words of my favorite cartoon character ever, "I just got bored. Everybody out." ... JimmyTheCrab probably gets that reference ;)

Nice work, but the wolf pack will find some little thing to discredit you.

So true. Thank you for your comments

Jumping in front of a Iphone 7 camera and then having the balls stating you measured those jumps down to micrometers.
You're an utter disgrace to every proper engineer out there.

I appreciate your comment kind sir or ma'm, but I have spent the past three years of my life doing research to be able to make measurements that precise. You think I had money left for a fancy smancy camera? Self funding is hard.

Flat Earth Debate / Re: Non-debate proof for globe earth

These videos do nothing to debunk the theory we could primarily exist in a 2D flat universe and what we may be seeing is a 3D holographic projection.

Nice try though

Why is this relevant?

Flat Earth Debate / More Utterly Undeniable Proof of Flat Earth!
« on: July 21, 2017, 06:25:29 AM »
Fellow Flat Earthers and respected Globers. I have been working on this experiment for a few months now and believe I have disproved the spinning globe model of our planet, while simultaneously proving the Flat Earth model!

I graduated from the school of engineering and applied sciences at the George Washington University with a degree in Mechanical Engineering and am two years into a PhD at Carnegie Mellon University. I was introduced to the idea of FE by one of my classmates midway through last school year. I’ll admit at first, I was dubious about what she was telling me. After a couple of days of research, however, it all started to make sense. With a few sentences, she had opened up my mind to a level I thought was never possible. How could I have been brainwashed for all these years?



As time went on, I started realizing that there was a slight disconnect with the FE theories and the scientific methods I was learning in school. A lot of Globers were telling me that if I put these ideas to the “test”, the FE model would not hold up. In my heart though, I knew these ideas were right, and using the scientific methods and theories I have learned over the course of my education, I believe I have proved it! Below, I will describe to you how I did it.
 
*Disclaimer: I apologize to any other Flat Earthers who may have run similar tests. I have done a lot of research on this topic and have not seen anything like it on the web, but I am only human, so I may have missed the articles or blog posts.
 
To understand my method and logic, I must first explain a phenomenon that occurs from the spinning globe model that Globers believe in. If the earth were a spinning ball, centrifugal force would cause the equator to bulge out a little causing cities near the equator to be farther from the center of the earth than cities farther away from the equator. Below is an image to show this:



The globe on the left is what most Globers imagine the earth to look like. The “scientifically accurate” version of this model looks like the image on the right.
            Now, based on scientists’ theories of gravity, the farther you are from the center of the earth, the lower the acceleration of gravity. Therefore, if I measured the acceleration of gravity at two different locations on the planet, they should be different. BUT WE FLAT EARTHERS KNOW THAT THIS IS PREPOSTEROUS.
Since the earth is flat, it is just accelerating at 9.807 m/s^2 in space creating a uniform gravitational field. This means that if Flat Earth is correct, no matter where I measure the acceleration of gravity, I should get the same value… and that’s exactly what happened. Here is how I went about doing the experiment.



 I am originally from NY state and that’s where I took my first measurements. I used a condo that my uncle owns in up state New York to run my tests. I used an iPhone 7 video camera to record myself jumping, then analyzed the video frame by frame to measure my acceleration. Below is one of the frames from one of the trials.
 
I propped the phone using a vice and did not move it during all trials for the day. I was sure to mark exactly where everything was relative to everything else before taking my phone for the night. I also knew how far I was jumping from the camera with great accuracy (to within micrometers). I also measured my height to within micrometers. Using these two values, I was able get an extremely accurate value for my height off the ground for each frame. Since I knew the frame rate of the camera, I had a plot of my distance from the ground as a function of time. Using a simple formula, I was able to calculate the acceleration.

 I did this with 100 different jumps to account for random error. I then took a trip out to Indonesia and stayed with some relatives who live very close to the equator to run another 100 jumps. Here are plots of the results:




As you can see, the average is 9.807 m/s^2 in both places! I crunched the numbers and if the earth was actually a spinning globe, in the New York state location, I would be 19 km closer to the center of the earth so I should have measured 9.809 m/s^2. While in Indonesia, I should have measured 9.805. As you can see in the zoomed in plots, my data does not hit these values even with random error.
 
I have peer reviewed that data my self and even showed some of my colleagues who agree with me. I urge other Flat Earthers and Globers alike to run similar experiments so we can finally end this nonsensical argument once and for all!
