Watch a Möbius strip robot move and climb when hit by light
Zi Liang Wu at Zhejiang University in China and his colleagues created their strips from thin sheets of hydrogels, materials made from long chain-like polymer molecules linked together by water molecules. They made the strips into unusual shapes, such as a Möbius strip - a one-sided surface that results from a band with a twist in it - or a similar curved surface called a Seifert ribbon. A soft robot shaped like a Möbius strip can move when activated by light, and could be used to transport medicine and collect samples inside the body.

Giving the Milky Way More Arms | Dead Planets Society
Переглядів 3822 години тому
Galaxies come in only a few shapes, which are all very round looking. You’ve got spirals and you’ve got blobs. Not content with this boring assortment, Leah Crane and Chelsea Whyte want to shake things up a bit. First up they want to give our own spiral galaxy, the Milky Way, more arms. One, two… eight? As many as possible. But they don’t stop at “octogalaxy”. They also ponder on what it would ...

Do whales have their own alphabet? We’ve long thought the clicking sounds that sperm whales make is their way of chatting to each other, but those clicks may be even more sophisticated than we realised. After analysing whale recordings, researchers suggest the different click patterns are complex enough to form an alphabet - the closest thing to human communication we’ve yet seen in animals. We...

Zebras bob their heads to attract attention and initiate social interactions such as grooming or moving together. This may be one of the few documented examples of signals that animals use to coordinate their behaviour. The capacity for multiple animals to focus on shared goals or objects in their environment, known as joint attention, is key to cooperation in humans, but it has rarely been inv...

    Around 35:10, you say 'Decisions in your head are purely classical processes - most of your thoughts have nothing to do with quantum mechanics.' But surely your head (and its brain!) are themselves quantum objects - as are processes running in them? So your decision for pizza or curry (I'd go for curry) is itself a quantum process. You seem to be indicating a curious dualism - quantum, and non-quantum, processes. But my understanding of what you said earlier is that everything is quantum. All quantum, everywhere, everywhen. If this is not so, what have I misunderstood?

    Still waiting for the scientific community to investigate YOGA. It works, the best universities in the world use it. Should we give a little peak into what they are doing, even though that method doesn't use the scientific method?? Shall we? We are so fixated with the brain, and we leave aside the rest of the body. Other cultures have developed a very precise knowledge of what consciousness might be. Do we want to have a look to what happens to their brains and bodies? Can we? Is it too hard to accept that someone else was right, even though they weren't using the scientific method? It's never gonna happen. So materialistic we are as a community. We need to "see", we need to touch, if these two things are not there, we say "it doesn't exist". There you go; yoga says the exact opposite: that what doesn't exist, also exists! Does it remind you of anything? I don't know... like the universe made mostly of nothingness??? They call it dark matter, dark energy etc... daaaahhh Can we please, just see, explore, what they have done, just to see if they were just lucky in predicting EVERYTHING we are proving today.... after thousands of years that they have been saying the SAME EXACT THINGS. Is it too hard to explore? No, better to destroy their cultures and countries, and then define them as religions...... OMG... so stupid, so narrow minded. If you say to someone who practices yoga that that is a religion, they might spit you in the face. They normally wouldn't, because differently from "uncoscious" people, they can control their emotions, knowing what consciousness is.... GOODNIGHT WESTERN WORLD. When you'll come up with the solutions for your existential problems, that someone has already probably solved, but doesn't have any of your attention, probably the world will be already over. Thanks anyways for the non-effort towards its research.

    Here is the explanation for galaxy rotation curves/dark matter SHORT VERSION - General Relativity predicts dilation, not singularities. Mass that is dilated is smeared through spacetime relative to an outside observer. Dilation will occur wherever there is an astronomical quantity of mass including the centers of very high mass stars and the centers of the overwhelming majority of galaxies. The mass at the center of our own galaxy is dilated, in other words that mass is all around us. LONG VERSION - Einstein is known to have repeatedly said that singularities are not possible. In the 1939 journal "Annals of Mathematics" he wrote - "The essential result of this investigation is a clear understanding as to why the Schwarzchild singularities (Schwarzchild was the first to raise the issue of G.R predicting singularites) do not exist in physical reality. Although the theory given here treats only clusters (star clusters) whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The Schwarzchild singularities do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light." He was referring to the phenomenon of dilation (sometimes called gamma or y) mass that is dilated is smeared through spacetime relative to an outside observer. It's the phenomenon behind the phrase "mass becomes infinite at the speed of light". Time dilation is just one aspect of dilation, it's not just time that gets dilated. A graph illustrates its squared nature, dilation increases at an exponential rate the closer you get to the speed of light. Dilation will occur wherever there is an astronomical quantity of mass because high mass means high momentum. There is no singularity at the center of our galaxy. It can be inferred mathematically that dilation is occurring there. This means that there is no valid XYZ coordinate that we can attribute to it, you can't point your finger at something that is smeared through spacetime. More precisely, everywhere you point is equally valid. The "missing mass" needed to explain galaxy rotation curves is dilated mass. Dilation does not occur in galaxies with low mass centers because they do not have enough mass to achieve relativistic velocities. It has recently been confirmed in 6 very low mass galaxies including NGC 1052-DF2 and DF4 to have no dark matter, in other words they have normal/predictable star rotation rates. This also explains why all planets and all binary stars have normal rotation rates, not 3 times normal. There was clarity in astronomy before television and movies popularized singularities beginning in the 1960's. The concept of singularities was not taught in colleges prior to 1960. Nobody believed in them when Einstein was alive including Planck, Bohr, Schrodinger, Dirac, Heisenberg, Feynman etc.

    Where I came from, looking up at the sky at night was always an awe inspiring thing. Not because of light pollution, and not because of Auroras, but because we were looking back in at the Milky Way Galaxy from the outer edge. From the location of this current Earth you only see half of that. Our Earth and Solar System was on the end of the Carina-Sagittarius Arm Spiral, on the very outer edge of the Milky Way. Approx. 75,000 light years away, on the opposite side of the Galactic Core from the location of this Earth and Solar System. The Mandela Effect doesn't just involve trivial logo and spelling changes. And there is a plethora of evidence. This Galactic location ME has arguably the most credible evidence and proof than any other, because theres multiple residue from Carl Sagan stating the location. One case he's even in front of a classroom and has drawn the Milky Way on the blackboard, where he points the the location of Earth on the very outer edge. Theres residue from Neil deGrasse Tyson's StarTalk program returning from a commercial break he gives the location he is in the studio zooming out to its Galactic and Local Group location. Then the very first sentence of Douglas Adams's 'Hitchhiker's Guide to the Galaxy' has it. And approx. 80% of the classic 'You Are Here' ↘️ images of the Galaxy are the outer edge.
