Despite what most social media science news publications will lead you to believe, science doesn’t, and shouldn’t, always have an end application. In that way, it’s similar to the trend of stretching out ear lobes or, for that matter, any body modification that leaves your dear old granny nauseous.
Take a recent discovery from Harvard University (home of the sexually harassing football team): the creation of “time crystals”. Just that name alone makes me imagine a glowing, angular rod of awesomeness which, when slipped into the rectum, has the ability to manipulate time and transport you back to when you didn’t care about interest rates. The reality, however, is that the applications of time crystals are currently unknown. So, if it doesn’t cure cancer or make your smartphone better, why has it been published in the super fancy journal, Nature?
Reading the peer-reviewed paper (here) to find out, is about as useful as a magician with no palms.
“We observe long-lived temporal correlations, experimentally identify the phase boundary and find that the temporal order is protected by strong interactions. This order is remarkably stable to perturbations, even in the presence of slow thermalization.”
What the fuck is going on? It’s like it was written by a person who hasn’t had any intimate contact with actual humans, due to a sexual attraction to anime characters. I guess that makes sense…
Time crystals are a new form of matter that, until now, have only existed in theory.
In normal crystals, atoms are arranged in repeating and predictable patterns. In the common crystal example, table salt, there’s a neat structure of sodium and chlorine atoms repeated over and over again. In time crystals, the structure of the atoms operates in relation to time rather than in relation to space. (stay with me…I understand that your brain has just decided it’s not worth reading on)
The time crystals, created by the Harvard scientists, were small diamonds which had been treated so that loads of impurities were present in the crystal structure. Within each of these impurities, there are electrons. The electrons in the impurities have a property which is known as spin – either up spin or down spin.
The electron’s spin direction reacts to microwave pulses by flipping 180 degrees. Typically, we’d expect an electron’s spin to change with each pulse, but in the case of the time crystals, the spin changes after two or three pulses, not every time you microwave it. In other words, this structure responds to time, not just external forces.
After a load of microwave pulses, the spins could start to get out of sync and become randomly orientated. In the time crystal, however, the interactions between the impurities keeps all of the electrons spinning in the same direction.
So, I guess that’s cool but what about applications? Does it cure cancer or make smartphones better?
No. The anime bothering scientists don’t really know what the applications are yet, but to make themselves sound more sciency, they included the words “quantum” and “computing” so other researchers would take them seriously.
The lead researcher Mikhail D. Lukin said: “I haven’t got time to explain my research to you for your stupid blog”.
