  • The pyramids are made of granite. It has a density/weight of approximately 165 lb/cubic ft. As in, a 1x1x1 block weighs about 165 lbs. This block, assuming the standard person in this picture is about 5 ft (people have been getting taller over time) this block is maybe 20 ft cubed. Just an eyeball guess. That would put it at about 1,320,000 lbs.

    The picture has 6 people deep carrying the first stone with what looks like maybe 4 people across? Hard to tell. But going off 6x4 people, that would mean that each person would have to carry 55,000 lbs each.

    Would it be possible? I will let you guess from that. Next question, how many eggs to support it? After some google searches the textbook theoretical best an egg can support is some 300 lbs, but in practice is closer to 120-130 with support/positioning in place (think egg cartons holding them vs just on the ground). This would mean our 1,320,000 lb stone would take between 10,000 to 11,000 eggs to support it.

    How long would it take to get that many eggs??? Good question. Chicken normally lay about an egg a day. So 10,000 chicken take 1 day, or 1 chicken would take about 10,000 days. But what is a realistic amount? Well, let me tell you. In the rabbit hole I found myself in of jokingly replying to this, I found an entire dissertation on “THE EXPLOITATION OF LIVE AVIAN RESOURCES IN PHARAONIC EGYPT: A SOCIO-ECONOMIC STUDY” BY ROZENN F. BAILLEUL-LESUER (JUNE 2016)

    Captivating. Would recommend rabbiting down that hole. And on page 299 we can see that a Pharoah size flock would be about 2,000 Eurasia cranes or geese. So it would take us about a week to put that block in the picture on a bunch of eggs.

    Thank you for coming to my TED talk.

    Evey time I hear about the evil big pharma funding all the studies out there to influence them in they favor, I immediately ask, “where is this funding and how can I get it?”

    Because let’s be honest, unless the leg work is already done, they aren’t funding shit.

    On the flip side of that, I did do a study for 3M and their hearing protection devices (I am an audiology/PhD student) and the funding was great. There were also basically no strings attached other than “use this product, study workplace noise, be able to publish it”.

    I have learned that stats for research is a dark box that you put numbers into, shake it up, and then record the numbers that come out. I use SPSS, my advisor uses SigmaPlot, and another PhD student in my lab uses R. Sometimes I’m not even sure if we are getting the same numbers out of the shaken black box and I am too afraid to ask…

    ANOVA? Sure, it is those clicks in that menu. ANCOVA? MANOVA? sure, there is some thing I check off or some other spot I click on. What do they do? The computer prays to the number gods with a different accent, then I shake the ritual box and read the numbers that come out.
