Unsurprising. It's the natural byproduct of overproduction of scientists, brutally competitive job markets, and the shortsighted decisions to use publications as the primary metric for hiring and promotion decisions.

Anyone who is alarmed by this hasn't been paying attention to the perverse incentives scientists have been facing for decades.

Any advice for PhD dropouts? I spent years and years pushing against that boundary in an obscure corner of my field and it never moved. What little funding I had dried up and I left grad school with a half finished dissertation, no PhD, and giant pile of broken dreams.

I'm sure over the years you've known students who have started a PhD and not finished. What (if anything) have you said to them? Do you feel their efforts had any value?

In the US at least, it is entirely possible to teach at a university without a PhD. Community colleges are full of instructors with masters's degrees, and tons of classes offered by major universities are taught by graduate students or adjunct faculty without doctorates.

Your job title probably won't be 'professor', but you'll be doing basically the same work as one.

I think this result is obvious to anyone who has spent any time in the academic world, although it is nice to see some solid numbers behind it.

The harsh truth is that key to academic career advancement is who you know much more than what you know. I every single person I knew in graduate school who got a postdoc position did so through informal means (i.e. knowing someone who knew someone), and having letters of recommendation written by the right people from the right departments at the right schools opens all sorts of doors to the academic hierarchy that would otherwise be closed.

A generation ago or two ago, it was common for chemists to use taste and smell as a tools for qualitative evaluation of chemical compounds.

So older scientific literature is full of all sorts of knowledge that was obtained in ways that are shockingly unsafe by modern standards, including gems like the taste of all sorts of poisons and how large quantities of plutonium are warm to the touch.

I immediately Ctrl-F'd for 'funding'. There's your problem right there. If there's no money to support graduate students, you're never going to get enough researchers to replace the ones you have.

Additionally, graduate students tend to avoid selecting research areas they dislike or find disgusting. The most disturbing presentation I've ever watched was a slideshow given by a parasitologist in which I saw worms in parts of the human body I never imagined it possible for worms to be in. No wonder students aren't lining up to spend years of their life working with them.

That brings back memories. One of my first research projects in school was doing sketchy things with a Quanta-Ray Nd:YAG laser. I remember the distinct 'tack-tack-tack' sound of the Q-switching at 10 Hz which I used to create a laser-induced plasma right around eye level.

Fortunately I had the proper goggles on but was always terrified of catching a stray reflection and blinding myself. Now we live in a world of dirt-cheap high-powered diode lasers, and when I see all the stupid things YouTubers do with them with almost no discussion of proper eye safety, I wince.

As someone whose early scientific career was destroyed by null results, no. No one will publish your negative results. Unless you win the lottery and stumble across a once-in-a-generation negative result (e.g. the Michelson–Morley experiment), any time you spend working on research that yields negative results is essentially wasted.

This article completely glosses over the fact that to publish a typical negative result, you need to have progressed your scientific career to the point where you are able to do so. To get there, you need piles of publications, and since publishing positive results is vastly easier than publishing negative ones, everyone is incentivized to not waste time on the negative ones. You either publish or you perish, after all.

Simply put, within the current framework of how people actually become scientists and do research, there is no way to solve the 'file drawer' problem. You might see an occasional graduate student find something unusual enough to publish, or an already-tenured professor with enough freedom to spend the time submitting their manuscript to 20 different journals, but the vast majority of scientists are going to drop any research avenue that doesn't immediately yield positive results.

I also wish there were ways to publicly acknowledge (and hopefully support) those who spend years of their lives working towards PhDs they never finish. For many it is a deeply private loss, with so few people knowing what happened and even fewer understanding the biting sense of personal failure you can feel.

I never made any sort of announcement when I left, and so had very little closure. Graduate school just ended and just trying to survive demanded my full attention in other areas. All I have left now is my unfinished dissertation, complete with the acknowledgement section I wrote.

It reads like a eulogy to a life I never had, to the shattered dreams I left behind, and to the naivete of my younger self. Perhaps there is some poetic value in there, but no one but myself will ever read it now. When it finally disappears it will, appropriately, be in a manner similar to how my failed PhD ended, with no one noticing and no one mourning its passing.

As a chemist who has actually done micro fabrication work, this reads to me like a classic case of a non-chemistry company trying to do chemistry R&D and finding out it’s a lot more complicated to follow all the rules than they thought it would be.

Robust chemical safety systems (both equipment, procedures, and employees) are expensive to implement and maintain, and they don’t scale downward easily. Companies doing small-scale production or R&D tend to have the worst practices.

That said, the findings in this EPA report don’t seem terrible, just indicative of a sloppy small-scale operation. Finding labeling issues is the lowest of low hanging fruit for any sort of chemical inspector, and Apple not being able to manage even that is just sad.

Roman Roads (2017) 2 years ago

Rome had the advantage of access to essentially unlimited forced labor in order to build and maintain their infrastructure. Modern engineering is absolutely superior to Roman engineering, but we do have to contend with budget constraints, at least in part because we're not using slavery to build our roads.

I’m reading this more like “New York Times reporter discovers used electric vehicles exist, cost less than new ones.”

Used EVs have been affordable for years. In fact, cars like the Nissan Leaf have depreciated so quickly that they’re a downright bargain (as long as your use case lines up with the limited range).

It should be obvious at this point that Valve simply does not care about TF2.

There is no one at the organization that does more than the absolute bare minimum to keep the servers up and the loot crate cash rolling in.

At this point, I think it’s best for the player base to just give up on it and let TF2 rest in peace. It had a real good run, but in the end it died due to developer neglect. It’s time to move on.

This is far more common that you would think. Just a generation ago, science degrees required students to learn foreign languages (Russian, German, French, etc.) so they could read journals to be kept up to date on the latest scientific findings. There are still a significant number of 'lost' research out there waiting to be rediscovered and publicized.

As a counter example, I will offer my own experience in graduate school. I was one of the few married students and observed that nearly all the successful graduates students had the following in common:

1. They had competent PhD advisors 2. The advisors had stable funding sources 3. They were single

Of those three, #1 and #2 were by far the most important. Certain professors just knew how to run a good lab and were able to shepherd their students through the program efficiently.

As for the impact of #3, I found as a married student I had to balance my research and teaching responsibilities with the needs of my spouse. It added a level of mental and emotional stress my single colleagues didn’t have to deal with.

Ultimately, my balancing act was unsuccessful. I eventually dropped out of my PhD program and ended up divorced.

So yeah, based on my anecdotal (N=1) experience, being married doesn’t not help you to be successful in graduate school.

That’s only really true for bicycle with modern rubber wheels. Attempting to ride through the mud or on rough surfaces with wooden wheels would have been much more challenging (not to mention uncomfortable).

This is a systemic social problem, not a technology problem. If researchers wanted to double check every single one of their citations for subsequent retractions, they would simply have their graduate students do it.

The root of the problem is that it’s impossible to build a scientific career out of publishing negative results (assuming you can even publish them at all). What actually matters is that your original publication gets into a high tier journal and gets good press. Once that’s done, no one cares if what you published was garbage or not, because by the time anyone figures that out (if they ever do), you’ll have tenure, big fat multi-year grants, and will be out on the speaking circuit.

I’ve always been profoundly jealous of countries with right to roam laws and dream of a day when we might have some thing similar in the US. Here in the west we have so much public land that is effectively closed to access due to wealthy landowners litigating over stupidities like corner crossings so they can monopolize the use of parcels they don’t own.

A very thorough preliminary report. I've worked for a long time in quality systems, and this is a perfect example of a systemic failure. They've got work being handed off between Boeing employees and 3rd party contractors with insufficient controls in place to verify that very basic tasks are being performed.

I'd be curious to know how many non-conformances they typically see during assembly of a plane and whether management is actually allowing the quality department sufficient independence to investigate these issues and fully resolve them. I'm guessing that the production personnel are under tremendous time constraints and are constantly pressure the quality assurance people to sign off on whatever paperwork is holding up the line, no matter the safety implications.

Also, I think a lot of middle and upper level management needs to lose their jobs over this. I hope this mess ends up in textbooks and gets beaten into the head of every MBA student in the country.

Honestly, I think anything that brings more attention to the stupendously wasteful travel habits of wealthy individuals such as celebrities and politicians is a public good and should be encouraged.

Ms. Swift has essentially unlimited resources to protect her privacy, so perhaps she should choose a method of transportation that doesn't involve broadcasting ADS-B information across the continent as she travels.

Scrum Sucks 3 years ago

I'm a scientist that through a lateral career move has ended up doing something akin to software development. This means for the last few years I have attended daily scrum meetings for the project I'm working on.

Perhaps it's my inexperience with software development, or maybe it's specific to the company I work for, or the people on my team, but but I find the entire process a gigantic waste of time and mental energy. How does everyone else deal with this? Is there a better way that will help me not dread attending my standup?

This is sadly unsurprising. I have a foreign language degree and a bit over a decade ago, I spent some time trying to get a translation side-job off the ground.

Even then it was clear that , except for a select few languages, it was a race to the bottom with machine translation software as the driving force. I gave up on that career idea quickly.

Now I use ChatGPT and is does a great job. My experience with DuoLingo is it’s barely better than flash cards for language learning, and it’s no wonder they’re having a hard time making any money offering a product thats competition is cheaper and better.

We're trying to use technology to solve a legal / political issue, which predictably ineffective results.

Unfortunately, I don't even think improved state oversight will help until the underlying issue of qualified immunity is addressed. The current legal framework in the US literally rewards police officers for being ignorant of the law.

I spent a lot of my time in graduate school fabricating transmission diffraction gratings using electron beam lithography.

Turns out making a bunch of nanometer-scale straight metal lines one a flat surface is a lot harder than you would think.
