Yeah, all the pretenders and management saying if you can't show it in extreme simplistic elegance you obviously don't understand it enough. Eat shit.

... what Im saying is that I would just make up my own pretty curve, the scientific community would disagree but the public would accept it & grants would roll my way easier.

I remember the first time I saw ~~Newtonian~~ non-Newtonian fluids in video. I feel like my brain broke. How much more science have I been taught inaccurately?

The real world is crazy weird. This multiple freezing points post is also fucking me up too.

Newtonian fluids are just normal fluids, like water. The so not change their viscosity under sheer stress. I assume you mean non-newtonian fluids.

What were you taught wrong about those?

[–] [email protected] 1 points 1 month ago (1 children)

Yeah, you were right. Non-newtonian fuilds messed me up. I saw a gif of liquid that turn more solid when you hit it than if you ease into it. If that makes sense. I was confused by the change in density.

I just didn't know they existed. Is there a liquid that you could run over as long as you do it quickly?

[–] [email protected] 1 points 1 month ago

Yes, that exists. All you need is something that is attracted to itself. So to move it around slowly you only need little force since links can break an reform, but to move it around fast you need to break a lot of links at once. Simply put some starch in water and you have that.

The other way around would be something like toothpaste or ketchup.

Especially that bump right around 42%. You know they retested that multiple times with a “wtf is going on?”

Not only that - you know they still got a bunch of "ok, but are you sure you measured it right" questions even after explaining it all in the paper.
