I forgot to correct one very important mistake of Neil.
If you actually listen to the interview, you will hear that the engineer talks PRECISELY about the two types of surveys.
The smaller surveys should take into account the curvature but don't. Which is the problem.
The larger surveys are very rare.
Neil, you really have exposed yourself now. Calling it a fake, when you have not even listened to it, is bad, even for you.
I heard the interview. The two types of surveys are used for two types of measurement, large scale and small scale. Most surveys are small scale because that's what most demand for surveys require. Large scale surveys are rare because they are not needed as often, obviously.
But as is typical of your posts, you are ignoring the challenge I have given you.
If you'd like to make a case for yourself, then measure the angle between the sun and moon at the next quarter moon, which will be on April 3rd, as the video I posted above describes. Come back here, if you are capable that is, and post what your measurement was. Take your measurement in the late afternoon about a half hour before sunset, when you'll find the moon directly overhead and slightly to the north. Let's see if you can do something constructive for a change, instead of just complaining as if you were a woman.
Do you understand? Or not?
Measure the angle between the sun and moon that you see in the sky on April 3rd.
You have already missed your chance to see where the sun rises and sets on the spring equinox. So you'll have to wait for the autumn equinox for your next chance -- which you'll no doubt miss as well, because you don't want to know the truth, do you.
