Hi r/science!

A team of quantum engineers from our School of Electrical Engineering and Telecommunications have published a paper in Science Advances describing a new device that can measure the spins in materials with high precision.

Normally, commercially produced spectrometers require billions to trillions of spins to get an accurate reading, but the research team were able to measure spins of electrons in the order of thousands, meaning the new tool was about a million times more sensitive.

The paper is available to read here:

What was the "warmer temperature" the news release talked about. Not having to fill the spectrometer with liquid He (or even just less often, as well as the N2) would be great

They mention in the article that the sample still needs to be under a magnetic field, which will still require liquid He/N2 to cool.

Always good news. Simpler measurements make for an entire domino chain of improvements.

Scientists out here making insane breakthroughs and 48% percent of people will still say science doesn’t work haha

My deepest appreciation to all those ignoring the noise and advancing the world

Materials have purpose?

I was wondering about that weird phrasing too, but it makes more sense in context:

> particularly in chemistry and biology where it can be used to understand the structure and purpose of materials, allowing us to design better chemicals, drugs and so on.

Although of course there is still no fundamental purpose, it's a good shorthand especially in biology for "the role this plays in a complex system".

"purpose of materials" implies intelligent creation, no? what a stupid headline, or at least, lazy journalism.

I think it's just a word for properties it's not that deep...


ubermeisters t1_jc2wa26 wrote

it's a science article. they should be using appropriate terms, else how am I supposed to respect them anough to believe they have conducted proper science?

you can be fine with clickbait BS titles, that's all on you. doesn't mean that I need to feel or conduct myself similarly.


ChaoticJuju t1_jc2wps2 wrote

Appropriate to the reddit user or their actual intelligent target audience?

u/ubermeisters, "appropriate to the meaning of the terms being used, smartass. Nice attempt."

And who decides that meaning and how it's appropriate? You right? Or is there a secret league of article writers I haven't heard about? You are getting offended over the way you interpreted a word in an article


ubermeisters t1_jc2wsay wrote

No, it doesn't. I hope this answer helps.

answers require questions thanks, And mine was clearly rhetorical...
