Looking at phase diagrams is something that feels weird at first but turns out to be very nice. I think one reason it’s weird is that (when one follows the normal track of education through school and into a degree like physics or mathematics at university), this is the first time (at least in th uk school system) when one stands basically no chance of actually solving the equations but giving good useful qualitative information about the solutions is possible.

I think part of why it can be hard to learn is that one must guess what is in the unknown areas whereas in past problems with limited information (eg in geometry), the puzzle is to derive just enough information on the boundary to solve the problem, so one may not be able to say something about the areas of some figures but might have something to say about their sum.

I found the trick to phase diagrams was realising that they are mostly made of a few interesting features: at every fixed point the diagram is some combination of a circular motion and a scaling in/out motion, or it is some kind of saddle point going out in one direction and in at another (eg the fixed point at the top of the pendulum in the video). Then you just fill in the gaps. This feels hard at first because you can imagine there could be anything in the gaps but it is actually easy because the flow lines do not cross and one cannot have significant turbulence without fixed points (and those have all been found) so only boring things can be drawn in the gaps.

The same is also true with drawing contour diagrams, just replace fixed point with stationary point, and flow line with isosurface.

Though uncommon, XX children can have ambiguous genitalia at birth. Today (1) we have some idea on what it is and we can deal with it at various stages of growth in-utero, at birth, during infant development, at adolescence or even later? Faced with a similar situation the past, parents gambled (aided with biases and superstitions). Is that sufficient to call it idiocy, I do not think so.

"Nuclear is expensive in the U.S." seems like an inadequate rebuttal to an article that spends so much time explaining why it's expensive in the U.S. and how to fix it.

Some countries are able to do nuclear at much lower cost, e.g. South Korea.
If your definition of "interesting" is how much math it requires, I have bad news for you... :)

I'm a grad student in the US, I have more free time than this. I also had more free time when I was working (even more than I do now). I know very few people that have this little amount of time, and that generally is because they decide that they want to spend their time doing work.
Solid state has serious issues with power density and IR heating, the next battery chemistry for cars isn't going to be solid state Li-ion.

Magnesium-Air or Zinc-Air are interesting for automotive applications, since they have high specific capacity without sacrificing too much on power. Li-Sulfur also has potential, but it currently suffers from the same problems as Solid State Li.

I think one point of the article is that if you have a big system you don't need load-balancers or worry much about routing etc. The assumption also I think is that you have "one app" which you offer to the public.

Now on such a big system it might of course make sense to implement parts of the application as "serverless". When you have just one server (or 2, app and database) it is pretty much the same conceptually AS "serverless" since you don't need to worry about multiple servers when you don't have multiples of them.

In fact, there was a Science Versus podcast about the benefits of lithium in public drinking water. Lithium naturally occurs in some water sources more than others, and areas with more lithium in the water have better mental health.
A quibble:

The point about meltdowns is cute, but probably wrong; the insurance against meltdown is a negative thermal coefficient of reactivity, if I understand correctly. In other words, the thermal expansion drives the fuel out into the piping as the reaction heats up, away from the compact reacting core, and also reduces the density in the core, allowing more neutrons to escape.
But it's pretty fragile. You can imagine after this scandal some prestigious employer, say Goldmans or McKinsey declaring that they want to see on everyone's applications whether they are a legacy, small sport scholar, or child of a rich donor.

In fact that might benefit society an awful lot.

Yes, it is incredibly misleading. How many people are affected? In practice, do the end consumers see this price increase? What caused the price increase? When was the last price increase?

Catholics believe that all mankind is made in the image of God.

Just a month before Chernobyl happened, the staff at the Experimental Breeder Reactor-II in Idaho successfully demonstrated something new and incredible: passive shutdown. They had the reactor at full power and killed the pumps. It shut down and started cooling itself with natural circulation (no external/backup power needed). No control rods were inserted. This state would last indefinitely. Then they did it again, this time cutting off the heat sink. Same result [1]. This was the ultimate energy source. But we all turned our backs on this team. Clinton cut funding in '94 and the reactor shut down.

Advanced low-pressure reactors can do this, and eliminating loss-of-decay-heat-removal accidents takes the probability of a large early release well into the 10^-7 or even 10^-8 range according to probabilistic risk assessments.

So even though nuclear is, by the actuarial tables, almost as safe as you can get in energy systems, you're right that the public opinion is a big hurdle and that Fukushimas are not acceptable. These low-pressure designs get us there, and it's been demonstrated.

Molten salt reactors, liquid metal cooled reactors, and some gas cooled reactors all have this capability. It's basically the main event of what the nuclear industry called Gen IV reactors [2].

> But I agree that the devastation of huge areas of land is a problem, but let's also keep in mind that the reactors that blew up where early generations reactors.

With "early generation reactors" you mean all the ones that exist. The whole "next generation reactor" / "generation 4 reactor" thing is at this point nothing more than vague plans for what could be.

Reading about TEPCO’s management of their facilities and people both before and after the Fukushima accident doesn’t really mesh with this claim.

Nobody bucketed LGBTQ people with them, OP specifically said closeted LGBTQ people, meaning those those people for whom forced disclosure of their orientation could potentially form a basis of leverage.

Dropbox uncovers 264 vulnerabilities in HackerOne Singapore bug hunt
Yeah I saw that but I'm still largely unsure about a lot of bits and pieces about the game play. Mostly it's a matter of determining what's intended behavior and what's not (e.g. the traffic jams for no apparent reason that may or may not have other cars passing them in the same lane), but also what things like those big arrows on the road (that persist sometimes).
It's not much different from many polytheistic religions though - the idea that there's some kind of supreme proto-deity, from which other more specialized gods derive their powers (or even of which they're facets), is quite common.

And I don't think it's a stretch to assume that this is where the Christian cult of the saints derives from. Especially when you look at some of those saints, and see how they have effectively overlapped with some pagan deity from older times. For example:

Linux Benchmark Scripts and Tools
Unless you do solar and mostly skip wind, in which case you can build enough nuclear to run the nighttime load and solar for just the extra daytime load, then you can run the nukes 24/7. That minimizes both nuclear downtime and storage requirements.

But if we're going to build a lot of wind, that still doesn't necessarily doom nuclear, if we can lower the capital cost of nuclear. The article describes some fairly simple ways to go about that; a recent study at MIT had the same recommendations.

Down the road a decade or so, molten salt reactors will start to be available, and those look to have much lower capital costs and good load-balancing.
Almost certainly by choice. I've had a few jobs with terrible commutes (5-6 hours a day), which only leaves the weekend as free time. Losing most of one day to chores still leaves at least 16 hours a week of free time. I've also gone to school while working full-time, which leaves a similar schedule. And I've worked two jobs, which again leaves a similar schedule. I have a hard time picturing a single, childless person having only 4.5 hours of free time. What sort of obligatory schedule are you thinking of? Three jobs and a lot of commuting?
Also Molten salt reactors don't exist yet appart from a few research reactors, which you forgot to mention.
That's too simplistic. Retiring nuclear power plants has been the long term goal of the German anti-nuclear movement since the 70s. They were an important faction in the founding of the Green Party. When the Green party came into power in 1998 in a coalition government, they passed a law to retire all nuclear power plants by restricting the remaining energy output they could produce. BTW, this was done in consensus with the German nuclear industry. In 2009, a free-market/conservative coalition came into power again and they reversed course. Then Fukushima happened, a couple hundred thousand people demonstrated against nuclear power in Germany, a Green-led government won the elections in a historically conservative state, and Andrea Merkel changed her opinion.

Long story short, phasing out nuclear energy has been a long term goal and has broad support in Germany.
This all is true as a matter of Church doctrine, but the actual practice among worshippers is rather different (not just in Catholicism - same thing among the Orthodox).
Sure it is a non problem.

If your country is the size of the USA and nobody bothers if you let it disappear somewhere in the desert. Which is not the case in Germany and most of the countries. People just don't want to have a nuclear waste dump near by and Germany needs to spend a hell lot of money to clean up the last mine they used as a dump already.

The tech is dead and the lobby won't be able to ride that current artificial hype for ever...

Also the beginning of this statement is not really true:

> Germany, which went all-in for renewables…

This might have been the case more than a decade ago with the green party being part of the government but the political climate changed. Angela Merkel talks a lot about saving the climate but actual policy is the opposite slowing down the switch to renewable energy as much as possible.

> From what I read and hear Nuclear power is a great source of energy

Not really,

* It's expensive as hell, it just might seem cheap because a lot of the cost is offloaded to the tax payer in the long run

* Even western first world countries operate nuclear power plants which have known safety issues (look at e.g. France or Belgium) so even if we could technically do it safely, our societies are not politically mature enough to implement it.

* Uranium mining is an often overlooked environmental disaster so it's not even as clean as often advertised
Small Korean cars (Hyundai and Kia) have excellent reliability metrics in EU. They are, in some ways, equivalent to old Toyotas.

They are also backed up by great guarantees (5 years without mileage limit in case of Hyundai, and 7 years from Kia).

African markets used to love Peugeot 504 and Mercedes E 200. Extremely reliable in harsh conditions.
Process process process.

Start with researching formal "quality management systems." At the very least that'll introduce you to using FMEAs, external standards, rigorous design reviews and testing, quality gates between development and production (if they're not a PITA, they're not working) and traceability for everything in production.

There are off-the-shelf learning materials for all of it.

If you do go down that road hire someone with QMS experience to design your process and handhold your team through the transition. Otherwise you're likely to over-complicate it for a less effective result.
the practice of buying the cheapest version of something, in my experience, should not be applied to things like tools. there is a remarkable difference between a $20 no-name multitool and a nice Leatherman, or a nice pair of binoculars and a cheap Chinese knock-off.
electronics, of course, is a totally different story. everything has nearly the same brains, with perhaps a UI quirk or two on the cheapest version.

Not to speak for Americans but this is the classic immigrant story in America. I, personally, know many people who've done this.

It isn't about "this type of work" or "people taking it out on me". The world is a place. It is a certain way. I have an objective. To have my family better off. So if someone is going to yell, they're going to yell. It's just the constraint. I'm going to adapt to it.
Both the OP and the WSJ article are op-eds, written by people who are not paid by the publications. Op-Eds get their name from the phrase, “opposing/opposite the editorial page”, so it’s not particularly accurate to think of this as the NYT and WSJ stating a position.

You are aware that the "long-term strategy" had been to phase out nuclear, with laws and contracts laying out a gradual shutdown in place, and Merkels government slowed that process down against majority opinion in the population before Fukushima? The shallow "Merkel did it after Fukushima" meme is a mockery of what has been a long democratic process that Merkels government tried to renege on, with nuclear power having been a contested topic for decades.

Afaik, the main problem with Fukushima disaster was awful handling by Japanese management, mostly finger pointing, instead of fixing the problem.

In particular Fukushima case, the evacuation caused more harm than fallout would do, so, in retrospective, it would be better to not evacuate.

There is no "huge areas devastated and unlivable for generations".
The McClure's pickles with scotch bonnets are phenomenal; somehow the supply up here in Ontario never keeps up so I always bring some home when I visit Michigan.

No, nuclear is sadly not a viable solution, due to cost. If nuclear were affordable it would be pushed through regardless of opposition. But it has just not worked out.

The people with the money saw what happened at Vogtle and Summer (and also at Flamanville, Olkiluoto, Hinkley Point). Those efforts to make nuclear affordable failed spectacularly, even with public and government support. Westinghouse and Areva were just unable to execute.

This failure should not have been a surprise, as it mirrored what happened in the last big nuclear construction boom. That didn't stop because of accidents; it stopped because the nuclear plants in that boom experienced substantial cost overruns (i.e., the nuclear vendors were not honest about what the technology would actually cost.)
I'm interested in how this taxonomy of discussion works... can you define the lines between what is "fair" discussion, "talking points" "trolling" and "garbage"?

How to Safely Generate a Random Number
Generation III+ reactors are orders of magnitude safer than everything else that was built before the turn of the century. China is actually leading the charge right now, with AP1000 reactors under construction. One of the plants just went live last year: https://en.wikipedia.org/wiki/Sanmen_Nuclear_Power_Station

The US needs to find a way to make building reactors affordable.
All reactors have negative temperature coefficients of reactivity, including LWRs (the water moderator boils away), SFRs (the core thermally expands), and MSRs (the fuel density decreases). The key to avoiding radiation leakage out of any nuclear plant is decay heat removal [1]. If you can passively remove decay heat, your reactor is very safe. MSRs do this easily, as do other reactors with low-pressure coolants (like sodium metal-cooled reactors).
