Yup. That was my reaction at first, too. Definitely taught me a lot about informal trust systems in academia.

Sometimes the collusion is blatantly obvious. Back in grad school a colleague of mine spent nine months on an experiment in a new field and submitted it as a paper to a quality journal. Six months later, the paper was rejected for lack of n

Taiwan responded when their (assistant) minister of health came across posts on online forums claiming that there was a SARS-like disease being covered up in Wuhan. On Dec 31 they were screening passengers and on Jan 2nd they started asking

Before the Great Lockdown, that would result in the friends, family, and coworkers of the disappeared person contacting police and then media to find them.

We have been in a less than ideal evolutionary equilibrium with respect to security: in the short term, companies that don't fund security can outcompete the prices of companies that do fund security, but they leave themselves vulnerab

This might work for your personal system, but in the corporate environment, what's to keep someone with legitimate system access from emptying the wallets periodically and blaming an advanced persistent threat? It would be better to do

You're the second person who mentioned net-270 in this thread. What's the context?

This is significant. Current OLEDs at full luminance burn in within 100 hours. The problem is mitigated somewhat by the variety of details displayed during typical TV programming, but if you use an OLED TV as a daily driver computer monitor

Couple funny stories about Elsevier. I published with them, and created an account. They started sending me spam advertising new journals. So I logged in and unsubscribed from all their mailing lists. Reliably, exactly one year after unsubs

I bet it's also why cruise missiles use terrain navigation.

Is it also more ornerous to control for oscillations in pedestrian bridges? Does that require extra structure, or just tuning?

It sounds like you are describing monopolies or regulatory capture. And sure enough, the US and Germany have some of the least competitive infrastructure construction markets.

At industrial quantities, 3D printing is slow, low-quantity, and imprecise. You can fix one of those axes at the expense of making the others even worse. As an example, I designed a part with micron-scale tolerances. Some 3D printing firms

Farmers sweep things along the field all the time. The standard farming sprinkler is supplied by pipes / hoses which are bridged above crop height between wheeled towers. As the spinkler works its way in a circle on the field around th

I'm not sure that line cleaves along political affiliation, but I'm willing to be convinced. I know both Democratic party insiders who have pivoted to local political activism following the presidential election, and Republican bu

Isn't this effectively what is happening when a major media outlet writes a piece about how $SocialMediaCompany has a racist/sexist "bro" culture or allows racist/sexist $SocialMediaCeleb on their platform? As much

By keeping the paper, UMN is benefiting (in citations and research result count). Universities are supposed to have processes for punishing unethical research. Unless the University retracts the paper and fires the researcher involved, they

I would love to see election reform, but how to implement it so that it is not (perceived as) one party locking the other out of power indefinitely? I propose a 16 year lag from it becoming law to implementation becoming mandated: if the op

Obviously not the same type of facility, but I have seen buildings where the closing of smoke shutters opens otherwise locked doors, revealing an alternate fire escape from the corridor to the stairwell.

The line between scientific and non-scientific contributions can be fuzzy. One would not put the supplier of a chemical in the authors list ... unless the synthesis and distribution was done as part of a collaboration and it is the compound

Good point. That's a second-order effect I had not considered. However, orbital mechanics being what it is, that would not result in the Earth "sinking into the sun," which is the claim I was responding to.

A piece of extraplanetary mass being brought to Earth only changes the planet's orbit insofar as its orbit on entry to Earth mismatches that of rest of the planet. Furthermore, it will only slow down Earth's orbit if it was initia

Outside of the US it is not uncommon. I believe US eggs are washed with a detergent which kills salmonella and sterilizes any fertilized eggs. As a side effect, US eggs are more prone to spoiling at room temperature. Anyway, in Europe or As

The political agenda does not undermine the substantial point: American institutions have been shamelessly lying. This isn't new: the US entered Iraq on a lie and the NSA was caught lying to congress during the Snowden leaks. What has

One of the interesting things to come out in Dec 2020 is evidence that Wikileaks offered the State Department advance warning when the encryption keys for the Iraq War Logs were about to be published by their collaborators at the Guardian.
