Thanks to a complex mathematical algorithm, these plastic shapes follow a very specific route as they roll. In fact, researchers have shown that a shape can be designed to follow almost any path you can think of.

Wow, you can design an object that will draw a line replicating a human ECG or replicating the horizon line of some famous place as a souvenir.

I want a shape to write this!

Wanna simulate it. How? Checkout our review on computational modeling of non-spherical particles, here ( @NatRevPhys.

Yo, if you arent to busy can you solve the homelessness and drug problems.. maybe do some maths to get the economy going again

every matter in this uinverse repeat the same pattern while moving according to their shape... does it means we are also repeated.. multiverse is true... -Melin chaudhary

@cagrimbakirci There is something about Fourier Series but idk what exactly 🙂

Susan Kleinfelter she/her2 years ago

When the shape produces two identical copies of the path with non-identical parts of the sphere, would you call that pseudosymmetry? 🤔

Amazing story telling, I have no idea how it would be applicable but I want to order all the shapes to play around!

Hasn't the same principle been applied in the design of camshafts that open engine valves & similar mechanisms? We had a course called 'dynamics of machinery' in mech engineering. This of course seems to be a much more sophisticated approach mathematically

Updated my SVG-to-CSS converter to support multiple path elements. An easy way to convert complex SVG shapes into CSS. It's a single-element implementation with a single shape() value! You can also have the border-only version using border-shape.

Peskov on the talks in Abu Dhabi: "I cannot yet give an assessment. It would be a mistake to expect any high level of effectiveness from the first contacts. This is a very complex matter, with complex issues on the agenda. However, the very fact that these contacts have begun in a constructive manner can be viewed positively. Serious work still lies ahead." The usual evasive talk of "complex matters" and "constructive contacts," designed to delay peace and buy time while Russia continues to destroy Ukraine and commit genocide against its civilian population.

TAYLOR: NATO should be very interested in having Ukraine join. Ukraine has shown that it can stop Russians. That proves Ukraine can do exactly what NATO is designed to do: stop, deter, and fight Russians if they attack. So NATO would be much stronger with Ukraine as a member.

🇺🇸 ELON ON AI: “IF YOU CAN THINK OF IT, YOU CAN HAVE IT - THAT WILL BE THE FUTURE” "I'm Confident that AI and robotics will continue to advance -and they are advancing very rapidly- working will become optional. People will be able to have any goods or services they want. If you can think of it, you can have it. But at a certain point, AI will actually saturate everything humans can think of. And then it becomes a situation where AI is doing things for AI and robotics are doing things for AI and robotics, because they are running out of things to do to make humans happy. Because there is a limit, there are only so many people and only so much food. If you can think of it, you can have it. That will be the future." Source: Elon Musk, Nikhil Kamath

Trigger Warning ‼️ Temp Post, There’s a reason that Hitlers speeches are difficult to find.. “In these so-called democratic countries, the people as such are not taken into consideration at all, the only thing that counts is the existence of these few creators of democracy, in reality, money rules in these countries. They talk about press freedom, when in fact all these newspapers have one owner, and the owner is, in any case, the sponsor. This press then shapes public opinion. These political parties don’t have any differences at all, like before with us. You already know the old political parties, they were all the same. The struggle between the people and the hatred amongst them is being nurtured by very specific interested parties, it is a small rootless, international clique, that is turning the people against each other, that does not want them to have peace. JEWS!, they are the only ones who can be addressed as international elements, because they conduct their business everywhere, but the people cannot follow them.” Adolf Hitler

You think you have a right to a second opinion—but in most hospitals, that "right" is strictly limited to their own staff. It’s time for legislation that ensures patients can consult with the doctors they trust, regardless of hospital "privileges." As long as a physician's license is in good standing, their expertise should be available to you when you need it most. What do you think? Should you have the right to a second opinion from any licensed doctor?

Elon Musk: A future of amazing abundance means that if you can think of it, you can have it. “Sustainable energy, space travel, AI and robotics will bring amazing abundance to everyone. It’s really the only path to amazing abundance. It's not to say it can’t go wrong, but I think it’ll probably go right. It’ll be a future that you love. It’s the best future I can think of. Then, we go beyond the Moon, beyond Mars, and sail through the Rings of Saturn. Wouldn’t it be amazing if you could take a trip to Saturn? Frankly, if you have a trip to Saturn, I think things will be free in the future. It sounds nuts, but if you’ve got an AI-robotics economy that is anywhere close to a million times the size of the current Earth economy, literally any need you possibly want can be met. If you can think of it, you can have it. Iain Banks in his Culture books has it pretty much right: there actually isn’t money in the future, and there’s abundance for everyone. If you can think of it, you can have it. That means anyone could have a trip to Saturn—it won’t be just a few people. If you want it, you can have it.” From: Terafab announcement, March 21, 2026

Suddenly, people come with a certain spirit and say these words: You can drink. You can engage in premarital sex. You can be homosexual. You can be a promoter of the LGBTQ movement without knowing the agenda of that evil movement or even the warnings of the Popes. You can belong to any Christian sect to gain salvation. You can be pro-choice. You can use contraception. You can commit fornication and adultery. You can believe in any religion and still gain salvation. For them, the Galatians chapter declares: “As we said before, so now I say again: If any one preach to you a gospel, besides that which you have received, let him be anathema.” Galatians 1:9
