Actually I was listening to a podcast that explains this. They didn’t have levers yet. They did have other devices but no lever.

nohaybanda,

I think the lever here is a stand-in for mechanical advantage. I don’t believe anyone is seriously proposing they lifted the blocks with a very long stick.

GreenTeaRedFlag,

you can’t just not have levers.

intensely_human,

It was before levers

jol,

Lol of course you can. They were invented at one point. And before that point… You didn’t have them. I recommend: Let’s Learn Everything episode 49: Goosebumps, (Not) Alien Pyramids, and Nessie & Cryptids.

Pretty sure the Egyptians were smart enough. But the European cathedrals cannot be explained w/o aliens

TwinTusks,

Great Wall of China? Come-on, no body can do that. And its not aliens, its GOD, who show favors protecting his favorite people, the Chinese.

psud,

Not to mention the Chrysler tower. Def aliens

It’s fair to imagine the challenges a building team would face 2k plus years ago.

Like in this example, building levers that are strong enough to lift the load. I bet they broke a bunch of stuff.

But eventually they figured it out, via trial and error. Levers, ramps, etc. They probably couldn’t describe why those things were inherently the best way, but more approached from the “we tried 9 other ways and they suck. This is the best way.”

Next, the phrase “any sufficiently advanced technology is indistinguishable from magic” is relevant here, but in a backwards way.

Since we struggle to imagine what it would take for an ancient society to master the techniques to build these things, we therefore begin to grasp for unrealistic conclusions (magic…read…aliens).

Same goes for Europeans building cathedrals and stuff, the trick is the history, the methods and the results were more documented and understood.

There are some racism concerns that I think go beyond and around what I’ve discussed, which is more abstract. I’m not discounting the other topics, just not covering them here.

IHadTwoCows,

One thing is for sure: you can’t leverage those stones with a primed FJ 1x6 from Lowe’s. I’ll bet they went through quite a few of those!

NattyNatty2x4,

Lowe’s definitely made lots of USD getting the pharaohs to think the pyramids were a good idea

intensely_human,

Now what were you thinking about a backsplash here?

Bonus if they’re great references, specific to your topic, and not tangential related ones

The great pyramid of Giza weighs around 6 million tons weightofstuff.com/how-much-does-the-pyramid-of-gi…

An average human can apparently develop about 200N www.ccohs.ca/oshanswers/ergonomics/push1.html

Meaning that an average human would need a lever about 3×10^8 m long (considering a 1 metre load arm) to move the pyramid.

Do you find this credible?

ETA: some people think I’m serious. This is quite the flabbergast.

Rodeo,

You’re gonna need a bigger load arm. The pyramid is way more than a meter across.

drolex,

How much more? One metre, tops?

The ancient Egyptians utilized neither wheels nor work animals for the majority of the pyramid-building era, so the giant blocks, weighing 2.5 tons on average, had to be moved through human muscle power alone. But until recently, nobody really knew how. The answer, it seems, is simply water. Evidence suggests that the blocks were first levered onto wooden sleds and then hauled up ramps made of sand. However, dry sand piles up in front of a moving sled, increasing friction until the sled is nearly impossible to pull. Wet sand reduces friction dramatically beneath the sled runners, eliminating the sand piles and making it possible for a team of people to move massive objects.

I know how they’re built because I watch Witual. Internal ramp theory babeeee!

I am sure as hell I don’t look like that. The references is the most interesting reading. Also, wrong gender.

PoisonedPrisonPanda,

If this was meant to be a joke…

i dont get it.

NaN is specifically not a number.

MxM111,
@MxM111@kbin.social avatar

Well, at least it is used in place of a number. But what about QED.?

TAVAR, (edited )

NaN makes for a better Chaotic Evil, QED could just as well be Neutral Evil.

However QED always stands in the bottom right corner, I guess that makes the author of this chart lawfully evil

That is a valid point. Also, I learned something about JavaScript. Thank you!

Well, it’s something like the difference between { x: null } and { }.

Valmond, to science_memes in Humanities be like

X can be a number.

I’ve taken like four or five advanced trigonometry courses and I still can’t really define what trigonometry is. Mathematics is like Andrew Tate’s Hustler University scam. If you take one class, it only exists to prove that you’re a mark and sell you more classes.

I enjoyed the trigonometry unit in my highschool geometry class, but that’s because it was mostly proofs, and those were just philosophy about triangles.

smeg,

Trig is basically the study of a wiggly line and how it turns out to be useful everywhere

I have a masters in math and I have no fucking idea what a second course in “advanced trigonometry” looks like much less a fifth
