> It may be easiest to think in terms of personal finance. Imagine you purchase a car for $20,000 in 2015, but under a special promotion no payments are due on your bill until 2018. In what year did you incur the $20,000 bill? Most people would say 2015, the year you acquired the car. That’s the answer mandated under accrual accounting, a method of financial reporting required of all public companies by the Financial Accounting Standards Board. But many state and city legislatures disagree. They operate with the conviction that a bill is not incurred until the money leaves your bank account to pay it. So if you choose not to pay the bill for your car until 2018, for accounting purposes the bill will only appear that year.

> Current accounting practices do not bear any relation to the future cash flow or the actual financial health of the city. When cities take on obligations, they should be properly accounted for as liabilities, not assets. When the city uses debt to build new infrastructure, it is taking on the double liability of both the current debts payments and the future maintenance obligation. The tax base associated with these obligations needs to also be accounted for as a cash asset (think of it like an annuity) discounted over the useful life of the infrastructure. Then we would have an accurate account of the obligations (liabilities) of the community and how that compared to the tax base (assets) that needed to support them. In short, a true account.

Crazy.
Yeah, I don't really know that much about refrigeration, but that's my take as well. If I had a choice, I'd just run all my stuff with propane, but I don't really know how feasible that is - could I just jury-rig up some hoses and go around charging things? Or are there parts of the system that won't abide by that?

I believe the stated rationale against propane is flammability, but is that really that much of a concern? Presumably you aren't mixing oxygen and propane in the system, so basically you've just got propane lines circulating in your house/car. Big whoop, I've got methane lines in my house already, and the car has plenty of other flammable things too.
I'd strip the "now" from your statement, this goes back at least to the 1887 Interstate Commerce Commission and many subsidy attempts which generally didn't produce economically viable railways or steamship lines.

Regulatory capture is a universal problem as long as a government is involved in an economy, and it has to be if for no other reason than to collect taxes.

You first have to understand the magnitude of the task.

I personally spoke with several programmers who wanted to "study physics". I showed them a copy of COMSOL multiphysics, explained to them that even as trained physicist with years of experience I could probably understand well only 20% of the problems the software can solve, and clarified that the portion of physics you touch on software like that is the tiny tiny part of physics that is used heavily in engineering tasks, maybe 1% of it, the most boring one. All of them without exception backed down.

The second thing you have to understand is that studying physics beyond the college level requires an analytical depth of reasoning that is not usually reached in software engineering and that there are no easy didactical books (in recent years the situation improved a lot though). So you either have to understand difficult stuff or you need a good in person teacher. Not to mention that only the mismatch between different conventions and schools of thought is gonna cost you a lot of your time if you rely on a sparse set of books. It happens a lot that different books use different space/time/unit/normalization/coordinate basis choices and that means you simply cannot copy and paste formulas without understanding their derivation.

That said I would suggest

- going through the exercises of a college level book like Halliday Resnick. Walter Lewin lectures if you can find them are good too.

- watch YouTube videos, some of them are really well made these days

- the theoretical minimum from Leonard susskind is a good set of lectures for advanced theoretical concept in minimal format for people who have some STEM background. A good series of books in the same style is the no-nonsense series from Jakob Schwichtenberg.

- go through the kind of stuff you do in computational physics. Simulations like you find in finite elements solvers are great visually. A lot of other techniques exist for modeling quantum systems, gravitational systems, statistical mechanics... Engineering-level stuff will have good software to back it (Synopsis for optics and semiconductors, Comsol for a holistic approach, Ansys for statics, Cst for antennas, Lumerical for optics,...). Most of those will have open source equivalents of significantly lesser quality. More research level stuff, like from DFT and beyond, will have open source packages that get sparser and sparser until you get to some github repository that a graduate student maintained for their thesis.
> On the one hand, as we know from the P vs. NP problem (at least if we assume the majority opinion), explaining a solution is much easier than coming up with it... and even easier if they copy from a good student who not only writes good code, but also documents it.

You can ask “tricky” questions that someone who understands the material shouldn't have a problem answering, such as “if the problem required you to also do this, how would you change your code?”.

"I questioned both students and I found that this one couldn't correctly explain how the code works, so I'm sure he didn't write it" is not.

Fair enough. But at least you can give a bad grade for not understanding the course material.

Okay, good to see that quantum mechanics
defines its use of correlation as

<(a - <a>) (b - <b>)> / (sigma_a sigma_b)

Good. Glad to see the actual definition.

That is, with usual quantum mechanics
notation, this is the usual Pearson
correlation coefficient and, thus,
appropriate to call correlation.

Fine.

Good to see that this is just what physics
is talking about.

My concern has been, does physics say
"correlation" when really they mean some
case of what we might call the usually
much stronger functionally dependent?

That is, for complex valued random
variables X and Y, they are functionally
dependent provided there exist functions
f and g so that

Y = f(X)

and

X = g(Y).

With this functionally dependent
situation, the correlation could be
anything from -1 to 1 but usually we won't
care because having either of X or Y
implies we also have the other exactly.

So, as I was reading quantum mechanics, I
was wondering if there could be, and open
to, two random variables functionally
dependent but without correlation 1 or -1
so that, really, talking about mere
correlation would be too weak and, thus,
not really appropriate.

Well, in the case of correlation 1 or -1,
there exists non-zero, complex a so that

Y = aX

in which case instead of mere
correlation it would be better to use
the stronger functionally dependent.

As I understand the situation, usually
quantum mechanics uses correlation for
examples of entanglement where it
appears that, yes, the stronger
functionally dependent would hold, and,
thus, be more appropriate.

That is, the usual uses of correlation
outside of quantum mechanics, say, in
statistics of medical research, economics,
finance, social science, mean "two random
variables not independent and also not
functionally dependent" -- having the two
random variables be independent (which
implies correlation 0) or functionally
dependent would be unusual.
Also, how would that impact cheating? I don't see the connection.

In 1945, the UK had far fewer people and it still had some slack when it came to resources such as land. Much of this slack has now been exhausted.

"The population rate of increase has been pretty constant since 1945" is actually a problem. This kind of eternal increase is not sustainable on a smallish island whose northern and western half isn't very suitable for housing.
Many engineers in the US do not have PEs even when it's an option. If you're not having to sign off on regulatory agency-related documents, potentially doing expert witness-related work, etc. there's no need for it.

I started the process at one point in mechanical engineering (engineer in training exam) but moved on to a different type of job so there was never a reason to get the certification.

I'm in a similar boat, and I think the answer is: same way physics students do, reading textbooks and doing exercises.

However I would not recommend the Feynman lectures (and, based on the preface, I think Feynman would agree). I've read about a 1/3 of the series and while I have to say they are some of the greatest technical writing in history, they are not the greatest pedagogical material. I do believe everyone should read at least some of the Feynman lectures, just not as a means of learning physics. Much like a good 3blue1brown video, you feel like you're learning a lot... but 6 months later there's just a big empty hole were knowledge used to be.

Based on recommendations I've found I'm currently working through Taylor's Classic Mechanics. My ultimate aim is to get a better grip on Lagrangian mechanics and make use of the plethora of great automatic differentiation tools out there to create some trick simulations of physical processes. So far the book has been fantastic, but I'm not far enough through to be able to give it an unequivocal endorsement.

Of course self learning does miss out on the experimentation portion, but I suspect a software engineer could afford the basic tools to setup a variety of high-school/early undergrad experiments. If you're hankering for something requiring institutional funding level of equipment you should be able to audit a course at your local university.
It's almost entirely because people really like technology that not only promises to reward you with excellent features and stability, it follows through on those promises.
Sizes of gas tanks and especially batteries vary significantly for reasons other than motor efficiency. Battery sizes can vary by a factor of two even between trims of the same EV model, so how many "gallons" fit in a "tank" depends on so many other variables that it makes any comparisons meaningless.

I'm pretty sure that "cost per distance travelled" unit is directly related to cost. I know you're trolling, I'm just debunking you for the benefit of others who may stumble upon this nonsense.

EV users have no reason to measure anything in an archaic USA-only unit for a dying technology. If you want to unify measurements to make them comparable, you should be converting gallons to Joules (e.g. 4GJ per tank of gas) or kWh (e.g. 1000kWh per tank of gas [this is a realistic number, BTW]). These are world-wide standard units of energy. kWh is used because appliances report their energy usage in kW, so it makes it easier for consumers to judge battery sizes and estimate energy costs when they're in kW per hour.

Insisting that USA-gas-gallon-equivalent approximation is the right unit for electricity is as trollishly anachronistic as measuring gasoline in bales of hay. How many e-bales-of-hay does your tank hold? How expensive is gasoline in dollars per bale of hay? If you fill a tank with 5 trusses of hay, does it mean ICE engines are more or less efficient than horses?

Instead of some kind of AI takeover I’ve thought for a long time that the most likely outcome is fusion, what I have called a “cybernetic lichen.”

A lichen is a fungus and a bacterium in symbiosis to the point that it behaves like a single organism. This would be similar: human brains and culture interwoven with AI to the point that it would be hard to figure out where one ends and another begins.

This doesn’t require neuralink or anything like that. It just requires a lot of human machine interaction and AI assisted work loads.

This is the lowest friction path and is also likely because human brains, conventional computers, and AI all excel at different things. This is by design. Humans have of course tried to engineer machines to do precisely the things we are either no good at or find horribly dull.

There's a big difference between a discussion between a few people to figure out an answer that they all understand, and posting the answer to a multiple choice question directly to the whole class.

To use the author's measuring stick, study groups typically engage with the course material. Learning that the answer to question 5 is "B" is not engagement.

Also, anecdotally, the study groups I was a part of were almost all based around figuring out answers to publicly available past exam papers, _not_ marked assignments. I think the sharing of answers (vs understanding) would have felt quite wrong to those of us involved.

This is a valid fear. I was in the same boat. Getting into great shape at 30 and having an extremely active life did me little favors when I simultaneously turned 40, went to school, and spent a lot more time in front of the computer. At this point, maintaining a healthy weight means eating less than half of the amount of food I ate at a healthy weight at 38, and it needs to be much more healthy. I'm fortunate in that I learned to cook and eat whole, healthy food early in life but despite being delicious and feasible, my diet is much, much more limited.

This summarizes the dangers of trifluoroacetic acid (TFA). It’s a small polar compound that has low potential for toxicity. I mean not great that it is in drinking water but in the grand scheme of things it could be much worse.

>As an acid or as a salt TFA is low to moderately toxic to a range of organisms. Based on current projections of future use of HCFCs and HFCs, the amount of TFA formed in the troposphere from substances regulated under the MP is too small to be a risk to the health of humans and environment.
Thanks for including energy usage in the article. I carry USB-C SSDs around the house for backups and storage of archived files. Of course this is a bit of a hassle and I played with the idea of either buying or building a NAS. My current standby consumption for all computer stuff (access points, router, switches, a dozen or so microcontrollers and various SmartHome stuff, but not TVs, running computers or gaming consoles) is already above 100w and I would really like to bring this number down. An extra 30-60w makes it really hard to justify the purchase of a NAS ( that I don’t really need). I thought at least the synonogies would use way less power when not in use, so thanks for making me aware of this.

The unlimited money is why gun control has become such a radicalized issue, so rather than a last resort because the other more important institutions are failing, I believe it is this radicalization around single hot button issues like the 2nd amendment that are the cause of these failures. That’s what I mean by it being a smoke screen. Convincing a large portion of the population that firearms are the only thing protecting their rights when instituions are failing is exactly what is making us head straight down the road to tyranny. We need to focus on fixing these institutions, guns only guarantee destruction, misery and tyranny.

This goes back to Reagan’s « the government is the problem », the government is not the problem, the government is us (or at least supposed to be). But maybe we’ve already reached the point of no return where there is so much money and power at stake that the system’s only purpose is to protect the interest of the people who have it.
I think using 1 disk redundancy is a mistake. It’s not only physical failure you’re worried about, it’s an error upon rebuild when you lose a drive. Bit rot on your remaining drives can occur which wouldn’t be detected until rebuild time when you lose a drive, and that could cause you to lose your entire volume. Bit rot can be checked for but you can’t always be sure and with larger and larger sets of data it gets slower to do.

I use raid 6 and also backup my data externally to another nas as well as backup to a static usb drive. Backup requires multiple different types since failures are so catastrophic and can occur in ways you don’t expect.
