I had no idea ... These findings always amaze me a lot

I visited one facility like it but smaller, it was meant to be a testing field for wave based energy production in high seas, as well as shell shape design like in your video facility. It was quite impressive. It is quite hard to simulated such an environment, because it's often veeeery windy in high seas and because waves reflection on the bassin edges are a huge no no in certain cases, so you need to account for that in some cases. Interesting stuff indeed!

Wow, what job or what you studying @laminutederire?

Yeah I was wondering about reflection and winds as well

I'm a student in a french engineering school. It was at Ecole Centrale Nantes, for their prototype! The facility is open to all twice a year. During their promotion day and during the science day. Since I'm from Ecole Centrale Paris, I might be able to negotiate visits or reading material for a Mapcore field trip :), since the schools are in the same group in a way.

I haven't worked on it though! My project was about datacenters cooling

Where I saw it, the wind was done with large fans all over the place blowing in ducts to channel the air flow. They could simulate high velocity winds with it. As for the waves, they used specific shapes for the edges developed to act as a filter of relatively low frequency waves.

the universe will in the future decide to fuck itself over and try again

better than the heat death concept.

Wonder if this already happened before.

Hi there Mapcore! Since it's the science thread, let me share a nice thing I became aware of again recently for a gift. I remembered the Gömböc, the object or 12 years of studies and the embodiment of a mathematical theorem. It's a precision piece with really amazing properties of stability. Has anyone heard of it and do you guys want me to fetch you all the infos about it?

This popped up on my feed and is interesting

@laminutederire does like something I heard of but nothing else so shoot away (maybe with a condensed version)

It's a mathematical object which embodies the theorem that there is such a shape in 3 dimensions which has exactly two equilibrium points, one stable and one unstable, while being cover and homogeneous. The manfucturing of such a shape took 12 years for Gabor Domokos. Funny thing is that it ressemble the shape of the shell of some turtles and insects, thus demonstrating once again the beauty of natural selection!

It looks like this :

I'm offering one to my gf as a symbol of harmony for our relationship, and as such symbol of Harmony, it was displayed in the Hungarian pavilion in 2010 for I think it was a universal fair.

It's also a symbol for mathematics, since it is a concrete image of an abstract theorem, as well as in a weird way, mathematical beauty.

Saw your video! That's an insane amount of dopamine we get. He hasn't talk that much about that, but I do wonder how it is correlated to dopamine release under irl social interactions, and if evolution made us social animals like this because of this addiction?

Yeah really good video, glad popped up! I was thinking instead of the video game aspect, I would imagine we have release in that as well

Thanks for clarifying the math, never heard of such thing, and definitely thumbs up to evolution... or was it? ?

This one can be huge: scientist apparently found a way to reduce use of water to grow plants, they are looking at reducing clean water use by 70% with this technique
