It's like something out of science fiction. In China, they've built a 35-meter plexiglass sphere 700 meters underground. It holds 20,000 tonnes of a strange liquid, surrounded by 43,200 photomultiplier tubes that can detect tiny flashes of light. It's deliberately built 50 kilometers from a nuclear reactor. It will start operation soon.

The goal? To measure some numbers in a 3×3 matrix.

It's called the Pontecorvo–Maki–Nakagawa–Sakata matrix. Unless we are seriously confused — which is always possible — this matrix controls the behavior of the 3 kinds of neutrinos. Neutrinos of the first kind are produced as a byproduct of nuclear fission. But they can turn into the other kinds as they shoot along. The rate at which they do is in part described by this matrix. (It also depends on the masses of the 3 neutrinos.)

What's the use of this? Easy: one goal of any prosperous civilization has always been to better understand the universe. It's just a tiny part of the grand scheme. It usually comes well after the goal of eating lots of tasty foods, or watching people run around playing with spheres. But sometimes it has huge effects, and some of us find it very exciting.

It's one of the most amazing things built by humans, and it's called JUNO, the Jiangmen Underground Neutrino Observatory. Check it out!

It should have been completed by November *2024*. As usual there were delays, but it's been built now, and it should start taking data this fall.

For more on the physics problem it's trying to solve, read on....

It's a cruel fact that we can't measure neutrino masses by looking at how neutrinos oscillate back and forth between the 3 kinds. We can only measure the differences in the squares of their masses!

This creates a lot of difficulties. In particular, we're still not sure if there are two light neutrinos and one heavy, or two heavy neutrinos and one light. (They're all quite light, but the chart shows what I mean.)

The first scenario seems more likely from the data we have so far, so it's called the 'normal hierarchy'. The second is called the 'inverted hierarchy'.

JUNO should help figure out which hierarchy is correct. It will also help with other questions. The three kinds of neutrino as measured by their *mass* are blends of the 3 kinds as measured by *how they're produced and detected*.

This blending is one of the things described by the Pontecorvo–Maki–Nakagawa–Sakata matrix. And it's also shown in the chart here.

The 3 kinds as measured by how they're produced and detected are called the e, μ and τ neutrinos. They're shown in red, green and blue in this chart. This chart shows how each of the 3 kinds as measured by mass is a mixture of red, green and blue!

For details on what we know and what JUNO will help figure out, try this:

• Francesco Capozzi, William Giarè, Eligio Lisi, Antonio Marrone, Alessandro Melchiorri and Antonio Palazzo, Neutrino masses and mixing: entering the era of subpercent precision, arxiv.org/abs/2503.07752.

Briefly, JUNO will help measure

m₂² − m₁²

and two other numbers that are functions of the Pontecorvo–Maki–Nakagawa–Sakata matrix elements. Alas, the numbers we can measure are not the numbers we most want to know!

Le barriere coralline sono ecosistemi estremamente vivaci e.. rumorosi!

I ricercatori di bioacustica che studiano il paesaggio sonoro del mare, hanno scoperto che questi ambienti in realtà non sono affatto silenziosi ma incredibilmente diversificati acusticamente.

Come sulla terraferma gli animali, una barriera corallina produce suoni sott'acqua, anche particolarmente forti, che possiamo immaginare come scoppiettii, cinguettii, grugniti e schiocchi.

The image shows a bakery display case filled with a variety of pastries and cakes. The display is organized into several shelves, each containing different types of baked goods. The top shelf features pastries like "Trança com Creme" and "Palmero Coberto," with prices ranging from 1.80 to 2.80. The second shelf includes items such as "Pecan Nudes" and "Carcol de Canela," priced between 1.20 and 2.20. The third shelf displays cakes like "Bara" and "Red Velvet," with prices from 2.20 to 2.50. The bottom shelf showcases larger cakes, including a chocolate cake and a passion fruit cheesecake, with prices ranging from 1.80 to 2.90. Each item is labeled with its name and price, written on small black signs. The display case is well-lit, highlighting the textures and colors of the baked goods, which include a mix of golden-brown pastries, creamy cakes, and vibrant fruit toppings.

Look, Jeff Atwood, it is difficult to take you seriously when you write authoritatively on a subject you clearly don’t understand.

GDPR doesn’t mandate cookie notices.

Cookie notices are *malicious compliance* by the surveillance-driven adtech industry.

If you’re not tracking people, you do not need a cookie notice, period.

If you’re only using first-party cookies for functional reasons, you do not need a cookie notice, period.

If you’re using third-party cookies to track people – i.e., if you’re sharing their data with others – then *you must have their consent to do so*. Because, otherwise, you are violating their privacy. Even then, the law doesn’t mandate a cookie notice.

How would you conform to EU law without a cookie notice if your aim wasn’t malicious compliance?

You would not track people by default and you would make it so they have to go your site’s settings to turn on third-party tracking if, for some inexplicable reason, they wanted that “feature”.

Boom!

No cookie notice necessary.

What’s that?

But that would destroy your business because your business is founded on the fundamental mechanic of violating people’s privacy?

Good.

Your business doesn’t deserve to exist.

Because the real bullshit here isn’t EU legislation that protects the human right to privacy, it’s the toxic Silicon Valley/Big Tech business model of farming people for data that violates everyone’s privacy and opens the door to technofascism.

infosec.exchange/@codinghorror…


Look, EU, it is difficult to take you seriously when you forced all this cookie notification bullshit on us. That feature a) should not exist and b) if it did, should be a BROWSER feature not "every website in the entire world now has to bother everyone forever about this stupid thing" blog.codinghorror.com/breaking…
