Does a thing sorta car-shaped without wheels count as a car? This thing never even had a lid. (You could call it a car, I guess... Rectangular, and you can sit in it.) Many people hope a legitimate sarcophagus, with an actual mummy in, might yet be found.

At which point of building a car separate parts become a car? And during maintenance (lets say engine replacement) is a car still a car? I'd say it is if meant to be used as a car again.

Right. So, is a stone box in a pyramid chamber that there is no evidence ever held a corpse, or even had a lid, and certainly will not have a corpse in the future, really a sarcophagus? It seems to depend on overconfident assumptions.

Given their experience, a decoy that looks like a looted tomb would just be good planning.

Thanks for the feedback! Didn't know if people would like this. If this is interesting, and you'd like to learn more about Ancient Egypt, here are a few more sites that I've worked at: Luxor Temple: https://luxortemple.mused.org/en/guided/178/luxor-temple Tomb of Queen Meresankh III at Giza: https://giza.mused.org/en/guided/4/tomb-of-queen-meresankh-i... I've mostly been working around the Mediterranean, Central Amer…

When I was in school, I visited my granddad during summer holidays. This was right before I would have history class for the first time at school, and my granddad showed me a book my dad gave him as a present, which was about the Pyramids in Egypt. I was fascinated by the book, and got to know that this is what history is about, so I got really excited. Holiday was over, school began, first hour of history class bega…

You might find some tiny encouragement seeing E.D. Hirsch's "Core Knowledge" curriculum efforts.[1] I don't see it on the reference page, but I have seen accounts of first-graders really taking to culture-and-civilization (and picture book) focussed units around "Ancient Egypt" etc.

IIRC, E.D. Hirsch, in his book Cultural Literacy, related a conversation with educators. He offerred that children should be able to name and identify Earth's continents. As he reports it, the reply as if with disbelief was "Why would anyone need to know that."

Semi-related, the Great Pyramid was also scanned using muon radiography, by which a "big void" was discovered [0]. Muons can penetrate through a lot of material, so they can see through very large, thick things like the pyramids. Muon tomography was also used to scan the Fukushima reactors [1] and see where the fuel ended up. [0] https://arxiv.org/pdf/1711.01576.pdf [1] https://www.world-nuclear-news.org/RS-Muons-sug…

Pessimism: We wonder how these pyramids were build thousands of years ago, and thousands of years from now, people will wonder what muons and such, which some later mythology refers to, might have been.

The Mused jobs link points at the blog, is that intentional?

Thanks, I'll update this--I've been working with a few of my friends this year, and I think we're still looking for product-market fit so haven't been thinking of hiring recently. Maybe since 19th and 20th century archaeologists have a sometimes terrible track record (Elgin Marbles, Benin Bronzes, etc.), it's important to not be similarly extractive with the 3d data now but instead find ways to connect the local and…

I noticed you have released some source code on GitLab, but it appears to be all rights reserved (no license information in the repo), but is also still viewable by the public, did you mean to make it a private project on GitLab instead?

As well loosely related, it is a few years that there are projects to use muograpgy to better undertstand how the dome of the Duomo in Florence was built by Brunelleschi:

maybe they will start this year.

Tomb robbers have not generally been given to making off with sarcophagus lids.

Tomb robbers are given to smashing anything that gets in their way.

Smart tomb robbers would have themselves buried in the tomb along with the king and all his gold, ostensibly to help him in the afterlife. Then they would escape out the back door.

Have they ever found any skeletons of these royal helpers inside any tomb?

It used to be common to execute retainers to help out the king or queen in the afterlife. Sometimes just a few, sometime hundreds. Supposedly everybody who worked on Genghis Khan's tomb was executed, along with his entire funeral procession, and all their executioners, so nobody would know where it was. It was finally found, just recently.

I recall a story where an Egyptian priest tossed the royal mummy in the Nile and committed suicide in the pharaoh's tomb, thinking himself clever for it.

You should try processing your photo dataset with a NERF based tool. They are much better at rebuilding the 3D structure from set of images. EDIT: There is this for example https://github.com/nerfstudio-project/nerfstudio

That's inventing details that don't exist in the data though, correct?

Don't think so. Pictures have to be taken from multiple angles with overlaps so that summing them up contain the whole thing.

This is so cool. I went to the pyramids last Xmas for the firs time. Great project. Sincerely.

Cheers and thanks for checking it out. I’m super curious: how does the virtual tour compare to your experience on site?

Very good! I'll never forget climbing those stairs, the tunnels, angles, etc. It was very interesting. No way someone with any bit of claustrophobia is getting up there. It was a little underwhelming getting to the tomb but still cool none the less. Experience you did here felt on point.

I almost gave my ticket to a guy faking working there. Haha
