physics is great, the physicists say things like "for the first fourteen point two bajillionoths of a second the universe was made entirely of bananas. and then the fruit field collapsed and for the next twelve nanoblinks there were only electrons and apricots" and i just go "that's great, tell me more" and yet despite the temptation to do so i don't think they're even trolling me, i think the thing about the fruit field might actually be true. or have been true for fourteen gigaquadillionths of a second after the big bang. aren't we lucky that happened or we'd all just be made of bananas? what a strange universe we inhabit.

#i love skience it's so weird sometimes #i am watching a youtube video about the higgs potential #the scientist is trying to make it understandable to laymen but i have no fucking clue whether any of this is true it just seems cool.#there's these tiny bisons that make things have mass and they wear tiny mexican hats on their little particle heads.#but also they're not particles they're a field and this is true of all the other things that we know like electrons and quarks and odos.#but maybe not neutrinos as there is a chance those are all left-handed which would mean they don't talk to the hat bisons at all.#this is fantastic stuff i love it. they should add new particles every few decades just to keep us all on our toes.

"Clothing tags, travel cards, hotel room key cards, parcel labels … a whole host of components in supply chains of everything from cars to clothes. What do they have in common? RFID tags.

Every RFID (Radio Frequency Identification) tag contains a microchip and a tiny metal strip of an antenna. A cool 18bn of these are made – and disposed of – each year. And with demands for product traceability increasing, ironically in part because of concerns for the social and environmental health of the supply chain, that’s set to soar.

And guess where most of these tags end up? Yup, landfill – adding to the burgeoning volumes of e-waste polluting our soils, rivers and skies. It’s a sorry tale, but it’s one in which two young graduates of Imperial College London and Royal College of Art are putting a great big green twist. Under the name of PulpaTronics, Chloe So and Barna Soma Biro reckon they’ve hit on a beguilingly simple sounding solution: make the tags out of paper. No plastic, no chips, no metal strips. Just paper, pure and … simple … ? Well, not quite, as we shall see.

The apparent simplicity is achieved by some pretty cutting-edge technical innovation, aimed at stripping away both the metal antennae and the chips. If you can get rid of those, as Biro explains, you solve the e-waste problem at a stroke. But getting rid of things isn’t the typical approach to technical solutions, he adds. “I read a paper in Nature that set out how humans have a bias for solving problems through addition – by adding something new, rather than removing complexity, even if that’s the best approach.”

And adding stuff to a world already stuffed, as it were, can create more problems than it solves. “So that became one of the guiding principles of PulpaTronics”, he says: stripping things down “to the bare minimum, where they are still functional, but have as low an environmental impact as possible”.

...how did they achieve this magical simplification? The answer lies in lasers: these turn the paper into a conductive material, Biro explains, printing a pattern on the surface that can be ‘read’ by a scanner, rather like a QR code. It sounds like frontier technology, but it works, and PulpaTronics have patents pending to protect it.

The resulting tag comes in two forms: in one, there is still a microchip, so that it can be read by existing scanners of the sort common within retailers, for example. The more advanced version does away with the chip altogether. This will need a different kind of scanner, currently in development, which PulpaTronics envisages issuing licences for others to manufacture.

Crucially, the cost of both versions is significantly cheaper than existing RFID kit – making this a highly viable proposition. Then there are the carbon savings: up to 70% for the chipless version – so a no-brainer from a sustainability viewpoint too. All the same, industry interest was slow to start with but when PulpaTronics won a coveted Dezeen magazine award in late 2023, it snowballed, says So. Big brands such as UPS, DHL, Marks & Spencer and Decathlon came calling. “We were just bombarded.” Brands were fascinated by the innovation, she says, but even more by the price point, “because, like any business, they knew that green products can’t come with a premium”."

Note: I know it's still in the very early stages, but this is such a relief to see in the context of the environmental and human rights catastrophes associated with lithium mining and mining for rare earth metals, and the way that EVs and other green infrastructure are massively increasing the demand for those materials.

I'll take a future with paper-based, more humane alternatives for sure! Fingers crossed this keeps developing and develops well (and quickly).

This is my (kinda new 😂) Walkman… And yes: this time I can really call it Walkman, cause this one actually is a Sony!

It‘s a WM 32 from somewhen 1986 and 89, so it‘s the most basic model by Sony, like no Radio, no Auto-Reverse or any other funny extras. But — that‘s still great: cause everything it doesn’t have…. can‘t break, and come on — it just looks great.

It also came with a belt-clip so I can actually wear it as part of my outfit, I’m literally so excited 🤣😁😁
