We did it! ^^

Your assumption is wrong. Consider, for instance, the LHC dataset, which reach O(EB). Just bringing the data into disks, loading into RAM in chunks, doing the data analysis and reduction, and doing the statistical analyses and fits, is a monumental task.

Consider now the work needed to operate the detectors, acquire the data, do calibrations and validations.

Notwithstanding designing, building and commissioning the detectors.

Please don’t assume lab automation.

I think this description is essentially correct.

But it is not a coincidence. Light — the EM field waves — propagates at causality speed because the EM field respects a particular property of the universe, the so-called gauge symmetry. That is intimately connected to the fact that the photobs has no mass.

Other similar particles, like the W and Z bosons, are manifestations of the weak field. Since that field breaks the symmetry, those particles have mass and move slower.

BTW, that symmetry breaking is the very same one that physicists talk about when we discuss the Higgs boson.

It’s exactly as in Mario Kart 64! Remember, heavy characters have the higher top speed, but light characters have the higher acceleration!

If I recall correctly, one of the first iterations of the prototype Playstation was exactly this. The original Playstation started as a collaboration between Nintendo and Sony.

A small nitpick: yes, we only needed 1 LHC to confirm the existence of the Higgs boson, BUT we made sure to have two experiments (ATLAS and CMS) looking for it. As far as I know, every modern high energy physics accelerator has had two (or more) sister experiments to cross-check each others!

Of course, it is not a perfect analogy, since the two experiments are not replicas. They try to address the same physics cases, but they were designed, built and are operated in a completely independent way.

This is a common hard-libertarian talking point.

Consider point 13.6 of Scott Alexander's (Slate Star Codex) Non-Libertarian FAQ:

https://slatestarcodex.com/2017/02/22/repost-the-non-liberta...

If you assume that "individual property earned through voluntary exchange" is the ultimate value to be upheld, you may end up having to defend a hellscape world. You need at least to temper it with something along the lines of the Lockean proviso.

They give a 30-day free trial, it seems (last item in the 5-reasons list):

"Triplicate has no demo version, but I do offer a 30-day return option: if the fonts aren’t your style, you can cancel your license for a refund."

"CERN found Higgs - which was proposed decades before CERN was built." ---> This is factually incorrect.

   * CERN: founded 1954, as a lab for nuclear physics

   * PRL electroweak symmetry breaking papers: 1964

If people were dying in troves of a disease (...) every effort would be put on saving them, right? How come some deaths are considered "fine", but others aren't?

No. Just No.

Let longevity come. Let immortality come. Let us live forever, sail the heavens, and travel to every world, every star, every galaxy, everywhere.

Disclaimer: I am Brazilian and a raving anti-Bolsonaro protester.

If we follow that line of thought, we will always end up at the following conundrum: the planet cannot support the "affluent Western" lifestyle -- think typical Bay Area HN-er -- for all 7 billion humans (as far as I remember, I don't have the sources for that).

Who is going to draw the golden ticket?

I agree that Bolsonaro is an opportunist (like many politicians), and he spews a lot of abominable statements. Unfortunately, his views align with a large section of Brazilian society. A society that was, from the beginning, built on layers upon layers of opportunism, manorialism and slavery. A society that cannot condemn its slave trade past, nor its many dictatorships.

Bottom line -- yes, I think you are in position to judge us.

Experiments at CERN use it. ATLAS has clocked 260k meetings, whilst CMS had around 130k.

In Brazil, there is an official residence for the Pres. and their family, but they could choose to live in some other official building. Pres. Collor (1991--1992) lived in "Casa da Dinda", instead if "Palacio da Alvorada".
