What's retirement?
Accujack··on There's a mechanical watch feature called a “hack”
Also recommended is "The Nekkid Watchmaker" for his excellent attitude and great explanations and ASMR versions.

You can also automate form filling with Simplify co-pilot: https://simplify.jobs/copilot

You have to re-type or cut and paste everything one more time, but it should be the last time you have to do it.

Accujack··on Safety inspector fired for finding 'too many defects'
The railroad companies that merged to create what's left of the rail industry in the US are the ultimate evolution of "too big to fail" corporations. They've been kept alive/subsidized for almost 200 years now, and they've had time to tilt the playing field to their advantage just like e.g. Amazon, except they've had a lot longer to pull shady stuff.

If you look into what privileges the railroads have, it's insane. In some places they have eminent domain ability, and immunity from eminent domain. Since most of the railroad regulations are Federal, they override state law as in this case in Ohio:

Basically... they're entrenched, and they've had 200 years to dig in.

Accujack··on Foxconn's promise to invest $10B in Wisconsin is now a distant memory
One useful outcome of this debacle is that it exposed a loophole in the Great Lakes Water Resources Compact.

Under that agreement, pumping water from the Great Lakes for industrial purposes is supposed to be disallowed, preventing e.g. chip makers or bottled water companies from buying land and setting up shop to pump water out of the lakes for export.

During this agreement, the city of Racine was given enough incentive to allow FoxConn to pull water from the lake via the city (there's an exception in the compact that allows cities who already pull their drinking water from the lakes to keep doing it). So Racine bypassed the compact by using their legal way to pump Lake Michigan water to supply FoxConn's industrial needs.

Fortunately this didn't happen, but the GLWRC needs some editin'.

Accujack··on Growing share of Americans favor more nuclear power
This is the classic anti-nuclear rhetoric

Always bring up the cost of nuclear power plants and the time to build them, but ignore that all the power plants built in the US in recent years use 1950s technology and are made expensive by 50 years of excessive regulation driven by fear.

Accujack··on The Fill and Flush deplaning method
Exactly. This proposal entirely ignores human nature, and the author has obviously not done any research into the problem beyond being annoyed while waiting to exit an aircraft.

There's this 2015 article on doing essentially what he/she is suggesting: https://www.vox.com/2014/7/8/5877863/it-takes-forever-to-get...

There's a paper on solving the problem by assigning passengers to seats so that their luggage is evenly spread throughout the overhead bins: https://www.sciencedirect.com/science/article/pii/S096969971...

There's a paper here on other methods tried, including creating "pre boarding" areas for passengers: https://www.researchgate.net/publication/269466040_Speeding_...

The first step in any scientific endeavor should always be a literature search.. see what's been tried, and what worked and what didn't.

Accujack··on LK-99 isn’t a superconductor
It's not over yet, at least not definitively. Nature Magazine like every other source so far is basing its comments on the attempted replications using the leaked paper. It's considered fairly certain at this point that the paper was incomplete/not enough to duplicate the material.

The full paper with the original samples were reportedly sent to Korea University of Science and Technology for examination. That lab group has only so far verified the structure of the material, no word on whether they've replicated it or its actual properties based on replicated samples or the original samples.

Until we hear from them, everyone (including Nature) is just guessing.

Accujack··on Ferromagnetic half levitation of LK-99-like synthetic samples
In this case, we have only a rough idea how close the leaked papers are to the final paper, with only one statement from a scientist at the national lab in SK stating that there are additional manufacturing steps in the final version of the paper.

I suspect there's a large difference between what was leaked and what will be formally published.

Accujack··on Do you avoid the news? You’re in growing company
>I don't know what could be done about it.

How about reinstating the fairness doctrine that changed (along with so much else) in the 1980s as a start? And creating some rules to prevent news sources from being used as propaganda machines by billionaires?

Accujack··on LK-99: Phonon bands, Localized Flat Band Magnetism, Models and Chemical Analysis
Or everyone has to wait for the full paper to be released which supposedly includes some manufacturing steps not included in the leaked paper so that replication can happen properly.

The original samples are now under testing at a national lab in SK.

Accujack··on Ferromagnetic half levitation of LK-99-like synthetic samples
What evidence?

Absence of evidence is not evidence of absence. They haven't even officially released their final version of the paper, and a whole bunch of people who don't have full access to their data being unable to replicate their material well enough to convince the world doesn't reflect at all on the validity of their work.

If the people to whom they have submitted their paper, data, and samples can't replicate it, that will mean something else.

Accujack··on Ferromagnetic half levitation of LK-99-like synthetic samples
That's exactly what they say they're doing. They submitted the final paper and the sample(s) to APL for review.

I don't think they have other samples to hand out.

They haven't actually published yet officially... the only papers everyone has their hands on (and which all the replications are based on) were leaked.

So, they're following the process... they've submitted the paper and sample for examination and they're waiting for those results before publishing.

Accujack··on Ferromagnetic half levitation of LK-99-like synthetic samples
Yet somehow those "SC people" issue this opinion without having seen the final paper nor the lab data on the original sample, which is presently being examined as part of the peer review process in SK?
Accujack··on JPMorgan Chase now says a recession looks unlikely
Like (for example) the commercial real estate market.
Accujack··on Andrew McCalip demonstrates synthesis of LK99
>This is simply what post-peer-review looks like.

No, this is a new face for peer review. Existing peer review processes have stagnated in the information age, possibly with good reason. There are a lot of advantages to more immediate review of papers and data, and also to bypassing the systems of qualifications presently used to choose who is a valid reviewer.

Accujack··on LK-99 is an online sensation but replication efforts fall short
This is how a lot of religions work, too.
Accujack··on Comcast, CenturyLink fail to derail Utah community-owned gigabit fiber network
>Competition works. In my experience, the dominant factor determining ISP quality is the presence of another ISP with a substitutable offering.

Yes. This is the root of the problem with Internet access in the US. The post-Reagan relaxation of antitrust enforcement has allowed many monopolies to grow, and combined with lobbying at all levels of government has created the stagnant environment we have now for Internet and wireless services.

>U.S. companies that are insanely competitive at making high-fructose corn syrup

They're competitive because it's subsidized, which is what makes it cheaper than sugar in the US.

Accujack··on Successful room temperature ambient-pressure magnetic levitation of LK-99
It's exactly like we got one critical item in the tech tree of humanity taken care of.
Accujack··on LK-99: The live online race for a room-temperature superconductor
The report of that I had was false, sorry. She has NOT said that.

Accujack··on LK-99: The live online race for a room-temperature superconductor
The author has acknowledged that one as a fake.
Accujack··on LK-99: The live online race for a room-temperature superconductor
China wants to gain a technological edge on all other countries. If they happen to be the first to turn a room temperature superconductor into usable commercial or military materials, then they'll have a huge military or economic advantage for some period of time.
Accujack··on LK-99: The live online race for a room-temperature superconductor
She's acknowledged her results were a hoax at this point.

She's also begging on twitter for people to stop attacking her since it's "getting to" her loved ones.

>So they have a batch of the material as proof, but no idea how to exactly reproduce it?

No, we don't know how to reproduce it, with "we" being everyone not on the South Korean team.

The papers everyone is trying to work from to replicate this are the "leaked" arXiv papers. That actual peer reviewed paper is still in process, and presumably that one includes more information on how to replicate the material.

Accujack··on The papers were not ready for publication
>I would be extremely sceptical that this would help electric planes all that much. Current brushless motors aren't really all that heavy for their kW output and already boast 90% efficiency at optimal load and RPM, which on a plane will be for the majority of the cruise.

The highest power brushless motors listed on Amazon are about 8kW (motorcycle hub motors). Superconductors could make possible a motor of the same size with approximately a 50kW output. The weight savings would be considerable.

Read this paper for more info - the paper also has a picture of a 5 MW high temperature (liquid nitrogen) superconducting motor, which is about the size of a car, and being tested for potential use in propelling large ships.

They have been granted the patent they requested in 2021 just recently in the US, FYI.

I kinda wonder if that particular vid was posted by YH Kwon... it would have been posted while he was still involved in the group.

It's very obviously not a U-235 disc by the color, unless the LK-99 film changes that somehow? Plus, if it's supposed to be pure U-235, why use that? Weapons grade enriched fissile uranium used in demonstration of properties of a thermally deposited film?

That video makes no sense at all.
