Thank you for doing this ama! Fascinating to read the Q&As.
Were the pyramids located in any specific orientation to astronomy (eg sunrise/set, constellations) and/or mathematical principles (eg integer ratios, Fibonacci sequence), or something else?

Complexity explorer. Residing in the liminal.

Thank you! Amazing to think how much ancients figured out astronomy and used it for deciding things like when to plant crops, etc. 
I wonder if they understood the earth is spherical?

Sorry for the delay. I had to call an expert as I'm not well educated in this part. There is no concrete evidence for this, all we have is speculation based on some studies such as the one proposed by Glen Dash, A theory in this regard, which is based on the ancient method of the "Indian circle" which requires a shadow stick and string to establish an east-west direction. He explained how this method could have been used in the construction of the pyramids. 

Also, a study from 2001 suggested that two stars, Megrez and Phad, in the constellation known as Ursa Major, may have been the keys associated with the method of aligning the pyramids. The lowest point of the two stars in the night sky could have been a sign of determining north using an ancient timekeeping instrument, which included a bar attached to a wooden handle to track the alignment of the stars.
