    I'm going through your older videos and find them interesting and valuable. A while back I took Coursera class on astro-archaeology. This professor claimed the shafts in the Great Pyramid of Khufu could not be ventilation shafts because vertical ones would sufficed and have been easier to make. He also claimed that the south facing shafts pointed to the stars in Orion's belt and Sirius. His conclusion was that the shafts were to "direct symbolically the Pharaoh to his proper destinations in the sky."

    • @LaunchPadAstronomy
      @LaunchPadAstronomy  6 лет назад +5

      That's very interesting. I understood it to be so that the Pharaoh could watch his kingdom but I'm willing to defer to the archeologists on that one.

    Early astronomy sounds more challenging than it does now due to a lot of reliance on assumptions, even Eratosthenes had to assume the distance between Alexandria and Seyene. Ptolemy's idea of epicycles and the difference around Earth to explain retrograde motion was very interesting, and definitely a thinker in his free time!

    • @geothon

      He had the distance measured by the hired professional walker. Sure he had to assume that the number he was given was correct, but the actual measurement was performed.

And Claudius Ptolemy had complied most of the work and published in Almagest. Julius Ceaser sieged the city in 48 BC and around the same time the library was set on fire. Ptolemy wasn't born until 100 CE. Could you please check this? How was Ptolemy able to gather information for his book?

    The problem with eratosthenes calculation is how did he know the distance of the sun? The entire calculation is based on the assumption that the sun is so far away that all the sun rays will be parallel to each other. It's not really scientific to just assume that.

    If you don't know that the heliocentric is the geocentric system from a different perspective then you should really not be trying to discuss this topic. (Psss the heliocentric system literally uses the measurements of the Geocentric systems. All actual real astronomers use the geocentric system because they live on earth). The Greeks probably gave up on the theory when they realized that if they're using the math and measurements from the Earth which makes up the geocentric perspective then it's exactly the same and there was no need to go through with the belief.
