While I appreciate the Nutty Putty Cave Incident callback, at what layer is the shark eating fiber optic cable?

[–] Soup@lemmy.world 3 points 10 hours ago

The one where the first several hundred metres is just water.

*Diorite*: Wait, is that a Mi

In case you didn't know, diorite is a real type rock as well that is similar to granite.

Apparently it’s xkcd 3171

The /// parts are carrying a lot of weight in this one.

I don't believe in dowsing, I have seen it done exactly once, and then a farm dam was dug with an underground spring directly in the centre of it, so my observations show it to have a 100% success rate from a sample size of 1, which is a bit awkward.

Wikipedia agrees with you. Commonly viewed as a psuodoscience. The equipment is very good at amplifying subtle hand movements.

I can see a little grain of truth in finding depressions and soft ground as the dowser shifts their body to stand level, which may indicate geological features associated with ground water.

Humans also have a really good sense of smell for petrichor, which might also be related to ground water, with dowsing just being useful to focus on suble things like smell.

Anyone who thinks dowsing can detect water directly is clueless or lying though, and dowsing has absolutely been used as a grift before.

I'm irrationality angry about the term 'bottom soil' and that it's below granite

[–] edgemaster72@lemmy.world 5 points 1 day ago (1 children)

Bottom soil: Is in the middle of the soils

Top soil #2: on the bottom

[–] sbeak@sopuli.xyz 4 points 17 hours ago

The earth is round, so bottom is actually top. Middle is deep inside the earth ("bottom")

Isn't water divining pseudoscience? I get that isn't the point of the post, but I always thought it was bullshit.

Uhhh is xkcd comics a geotechnical engineer??? Or a geologist?? This feels like an illegal loredrop

EDIT: fixed xbcd to xkcd

[–] Tlaloc_Temporal@lemmy.ca 2 points 8 hours ago

Randall does have a lot of geology humor specifically. I wouldn't be surprised if he knows a few geologist.

He's a professional geek
