The only true flaw of this cube comes from the weaker outer magnets : they make slices fantastically comfortable, but the weaker pull doesn’t let you finish your turns precisely with ease, and the core magnets are unable to compensate for it. Factor in the flexibility of the cube and you...
Carmel Majidi at Carnegie Mellon University and his colleagues created a millimeter-sized robot that can not only shape-shift, but also become stronger or weaker by alternating (交替) between being a liquid and a solid. When solid, the material was strong enough to support an object 30 times...
Hard disk drives (HDDs) are cheap and provide a lot of storage for the money. Because they use magnets and spinning platters, they're also more prone to failure. You might be interested in configuring your media server inRAID 1, which mirrors one drive to another, if you're concerned ...
The powerful magnets necessary make scanners pricey and also dangerous for people with metal implants. The new device hits a sample with a 30 millitesla magnetic field, about 100 times weaker than is normally used in MRI. The device then uses a 46 microtesla magnetic field—about the same ...
However, if, for these questions, not the electromagnetic waves, but electrochemical communication plays the crucial role, the experimenter may hope to make signaling weaker by answering the questions faster. The problem of question-dependent mental state modification seems to be solvable via smarter ...
