  • I am a software engineer by trade, so when I started cooking, everything and every tool was intimidating, because I had no idea how it worked nor what it was meant for. I knew nothing about knives besides not to drop one, didn’t know the difference between a wok and a skillet, and didn’t understand how oil creates a non-stick surface on a non-non-stick pan.

    What helped me was a book that wasn’t like a recipe or cook book, but something closer to a food and kitchen textbook. The Food Lab by Kenji Lopez-Alt goes into some excruciatingly scientific detail about the role of different kitchen implements, and then showcasing recipes that apply theory to practice. Each step in the recipes thoroughly describe what to do, and the author puts a lot of content onto his YouTube channel as well.

    It was this book that convinced me to buy, strip, and season a cast iron pan, which has already proven its worth as a non-sticking vessel comparable to my old Teflon-coated pans. And I think for you, reading the theory and following some of the recipes might develop sufficient experience to at least be comfortable in an active kitchen. It’s very much a chicken-and-egg problem – if you’ll pardon the poultry pun – but this book might be enough to make progress in the kitchen.

    Also, since it was published in 2015, it’s very likely available at your local library, so check there first before spending money to buy the book. Good luck with your culinary development!


  • I was once working on an embedded system which did not have segmented/paged memory and had to debug an issue where memory corruption preceded an uncommanded reboot. The root cause was a for-loop gone amok, intending to loop through a linked list for ever member of an array of somewhat-large structs. The terminating condition was faulty, so this loop would write a garbage byte or two, ever few hundred bytes in memory, right off the end of the 32 bit memory boundary, wrapping around to the start of memory.

    But because the loop only overwrote a few bytes and then overflew large swaths of memory, the loop would continue passing through the entire address space over and over. But since the struct size wasn’t power-of-two aligned, eventually the garbage bytes would write over the crucial reset vector, which would finally reboot the system and end the misery.

    Because the system wouldn’t be fatally wounded immediately, the memory corruption was observable on the system until it went down, limited only by the CPU’s memory bandwidth. That made it truly bizarre to diagnose, as the corruption wasn’t in any one feature and changed every time.

    Fun times lol





  • So far as I’m aware, non-occupational pre-nominal honorifics inure to the individual, so generally speaking, if that person doesn’t want to use their title, they don’t have to. And in the same way that most people will go along with someone’s acquired honorific of Dr or Capt or whatever, the same should also apply if someone expressed that their honorific should not used. I have no citation for this, other than what I’ve seen in life.

    As a sidenote, in Britain, I understand that medical doctors are able to use the pre-nominal of Dr, but surgeons specifically will drop the Dr and just use Mr. or Ms.

    Apparently this stems from ages ago when surgeons did not have to have a medical degree, and the doctoral view was that surgeons were akin to butchers. This may have reflected the crudeness of early surgeries. As a result, surgeons developed a history of being Mr – it’s not clear if female surgeons also took on Mr. So after the various laws/rules changed so that surgeons also had to be medically qualified, they still kept the tradition of Mr.

    Thus, a male student of medicine in the UK could go from Mr, graduate to Dr, and then graduate as a surgeon to Mr again. I have no citation for this either, but it’s plausible for the ardently traditional British nation.


  • If you were to properly consider the problem the actual cost would be determined by cost per distance traveled and you essentially decide the distance by which ever you are budgeted for.

    I wrote my comment in response to the question, and IMO, I did it justice by listing the various considerations that would arise, in the order which seemed most logical to me. At no point did I believe I was writing a design manual for how to approach such a project.

    There are much smarter people than me with far more sector-specific knowledge to “properly consider the problem” but if you expected a feasibility study from me, then I’m sorry to disappoint. My answer, quite frankly, barely arises to a back-of-the-envelope level, the sort of answer that I could give if asked the same question in an elevator car.

    I never specified that California would be the best place to implement this process.

    While the word California didn’t show up in the question, it’s hard to imagine a “state on the coast” with “excess solar” where desalination would be remotely beneficial. 30 US States have coastlines, but the Great Lakes region and the Eastern Seaboard are already humid and wet, with rivers and tributaries that aren’t exactly in a drought condition. That leaves the three West Coast states, but Oregon and Washington are fairly well-supplied with water in the PNW. That kinda leaves California, unless we’re talking about Mexican states.

    I’m not dissing on the concept of desalination. But the literature for existing desalination plant around the world showcases the numerous challenges beyond just the money. Places like Israel and Saudi Arabia have desalination plants out of necessity, but the operational difficulties are substantial. Regular clogging of inlet pipes by sealife is a regular occurrence, disposal of the brine/salt extracted is ecologically tricky, energy costs, and more. And then to throw pumped hydro into this project would make it a substantial undertaking, as dams of any significant volume are always serious endeavors.

    At this point, I feel the question is approaching pie-in-the-sky levels of applicability, so I’m not sure what else I can say.


  • I’m not a water or energy expert, but I have occasionally paid attention to the California ISO’s insightful – while perhaps somewhat dry – blog. This is the grid operator that coined the term “duck curve” to describe the abundance of solar energy available on the grid during the daylight hours, above what energy is being demanded during those hours.

    So yes, there is indeed an abundance of solar power during the daytime, for much of the year in California. But the question then moves to: where is this power available?

    For reference, the California ISO manages the state-wide grid, but not all of California is tied to the grid. Some regions like the Sacramento and Los Angeles areas have their own systems which are tied in, but those interconnections are not sufficient to import all the necessary electricity into those regions; local generation is still required.

    To access the bulk of this abundant power would likely require high-voltage transmission lines, which PG&E (the state’s largest generator and transmission operator) operates, as well as some other lines owned by other entities. By and large, building a new line is a 10+ year endeavor, but plenty of these lines meet up at strategic locations around the state, especially near major energy markets (SF Bay, LA, San Diego) and major energy consumers (San Joaquin River Delta pumping station, the pumping station near the Grapevine south of Bakersfield).

    But water desalination isn’t just a regular energy consumer. A desalination plant requires access to salt water and to a freshwater river or basin to discharge. That drastically limits options to coastal locations, or long-distance piping of salt water to the plant.

    The latter is difficult because of the corrosion that salt water causes; it would be nearly unsustainable to maintain a pipe for distances beyond maybe 100 km, and that’s pushing it. The coastal option would require land – which is expensive – and has implications for just being near the sea. But setting aside the regulatory/zoning issues, we still have another problem: how to pump water upstream.

    Necessarily, the sea is where freshwater rivers drain to. So a desalination plant by the ocean would have to send freshwater back up stream. This would increase the energy costs from exorbitant to astronomical, and at that point, we could have found a different use for the excess solar, like storing it in hydrogen or batteries for later consumption.

    But as a last thought experiment, suppose we put the plant right in the middle of the San Joaquin River Delta, where the SF Bay’s salt water meets the Sacramento River’s freshwater. This area is already water-depreased, due to diversions of water to agriculture, leading to the endangerment of federally protected species. Pumping freshwater into here could raise the supply, but that water might be too clean: marine life requires the right mix of water to minerals, and desalinated water doesn’t tend to have the latter.

    So it would still be a bad option there, even though power, salt water, and freshwater access are present. Anywhere else in the state is missing at least one of those three criteria.




  • For the historical questions, I don’t really have answers, especially where it involves departures from the Western world. I did, however, briefly touch up on Islamic banking, which I’ve always found intriguing as the Islamic faith does not permit charging interest on loans, viewing it as usurious. I’m informed that Christianity also had a similar prohibition on usury, but apparently it fell due to the need to fund the constant wars in Europe.

    I’m not really seeing the difference in feudalism except a members only kind of participation with a crony pool of inbreds, not all that different than the billionaires of today.

    I think the important distinction insofar as stock markets is that the crony pool of inbreds have access, but so too does the commoner. Well, the middle-class commoner usually. And we’ve seen David-vs-Goliath cases where the commoners put up a decent fight against the inbreds’ institutions; the whole GameStonk fiasco comes to mind. An equivalent economic upset would have been wholly impossible at any point during any feudal period in history.

    What are the idealist or futurist potential alternatives between the present and a future where wealth is no longer the primary means of complex social hierarchical display? My premise is that basing hierarchical display on the fundamental means of human survival is barbaric primitivism.

    From conversations I’ve had previously, possible answers to that question are presented in the works of Paul Cockshott, author of Towards A New Socialism. I’ve not read it, but friends in Marxist-Leninist parties have mentioned it. The Wikipedia page, however, notes that it’s an economics book, which could be fairly technical and difficult to read. Sort of like how Das Kapital is more-or-less a textbook, in contrast with how Wage Labour And Capital was meant for mass consumption.

    Wealth extraction neglects the responsibility of the environment and long term planning.

    True. The cost to the environment is not “internalized”, to use the technical term. Hence, it doesn’t need to be paid for, and is thus “free real estate”. Solutions to internalize environmental harm include carbon taxes or cap-and-trade. But the latter is a lukewarm carbon tax because it only looks at the end-result emissions, rather than taxing at the oil well, so to speak.

    I’m curious how humanity evolves in a distant post scarcity future but without becoming authoritarian or utopian/dystopian

    Might I recommend The Three-Body Problem and the trilogy overall by Liu Cixin? This phenomenal hard scifi work describes a space-faring future where the human species faces a common, external threat. After all, much of today’s progress was yesterday’s scifi. So why not look to scifi to see what tomorrow’s solutions might be. It’s no worse than my crystal ball, which is foggy and in need of repair.


  • If you’re in the USA, I cannot understate how useful it may be to refer to the US Bureau of Labor Statistics’s (BLS) Occupational Outlook Handbook (OOH), a resource which I believe has no direct comparison:

    How can I learn about an occupation that is of interest to me?

    The Occupational Outlook Handbook (OOH) provides information on what workers do; the work environment; education, training, and other qualifications; pay; the job outlook; information on state and area data; similar occupations; and sources of additional information for more than 300 occupational profiles covering about 4 out of 5 jobs in the economy.

    As for answering the question, anecdotal conversations I’ve had suggest that the trades (eg glazier, electrician, plumber) in the USA are promising fields, since while the nature of the job might change with different needs, people still require electric wires and piped water. But the OOH could give you more specific outlooks for those specific trades.

    I was once told that plumbers can make very serious sums of money, even if they’re only ever installing supply-side piping. That is to say, the plumbing for water supply, as compared to drainage or sewer pipe, which are generally perceived as less appealing.


  • I’ll take a shot from the hip at this question, but note that I won’t add my customary citations or links.

    The stock market is the paragon of property and trusts, contracts, corporations and law, and the capitalist socio-economic system. The very existence of the stock market implies a society that has some or most of these concepts.

    For example, for shares to be traded, there generally must exist ownership rights upon the shares, distinct from the ownership rights that the company has of its own property. Or if not outright ownership of a share, then the benefit that a share provides (eg dividends). It also implies a legal system that will enforce these rights and the obligations of the company to its shareholders.

    For a tradable company to exist, it must be organized/chartered as an entity distinct from any single person. This is different than the feudal days, when ventures would be undertaken “in right of the King” or some member of the nobility. The feudal method wouldn’t work for modern companies, or else the King/Duke/Count/whatever could stiff the shareholders by just taking all the earnings. The company still needs to be created by legal means, either an Act of Parliament/Congress, by letter patent from the Monarch, or the modern administrative method of applying to the state Secretary of State (USA) or Companies House (UK) as examples.

    Even the structure of a for-profit tradeable company – when compared to a state-owned enterprise, a non-profit, a co-op, or an NGO or QUANGO – is a representation of the values inherent to capitalism. A company is obliged to use the shareholders’ funds – which is held by the company but is owed to the shareholders – to extract the greatest return. But this can come in many forms.

    Short-term value from buying investments and quickly flipping them (eg corporate home buyers) is different than rent-seeking (eg corporate landlords) and is still different than long-term investments that actively work to build up the value (eg startup incubators, private wealth funds, Islamic banking, transit-owned adjacent property). If a for-profit company doesn’t have a plan to extract a return… they’re in hot water with the shareholders, with penalties like personal liability for malfeasance.

    Another way of looking at the stock market is that if you have all the underlying components but don’t yet have a stock market, it would soon appear naturally. That is to say, if the public stock markets were banned overnight, shares would still trade but just under the table and without regulation. But if any critical part underpinning the markets stopped existing, then the market itself would collapse.

    History shows numerous examples where breakdowns of the legal system resulted in market mayhem, or when corporate property is expropriated for the Monarch’s wars or personal use, or when funds invested into or paid out of companies is hampered by terrible monetary inflation.

    As for what the stock market does, its greatest purpose is to organize investments into ventures. Historically, ventures were things like building a ship to sail to the New World and steal obtain goods to sell at home. Merchant ships were and are still very expensive, so few singular persons could afford it. And even if the could, the failure of the venture could be catastrophic for that person’s finances. Better to spread the risk and the reward amongst lots of people.

    What was once the sole domain of the landed gentry and nobility, slowly opened to the nouveau riche during the Industrial Revolution(s), then in turn to everyday people… for better or worse. It’s now almost trivial to buy a share in any particular listed company, but just opening the stock market to everyone would have been chaotic at best. I think it’s NYSE that still has on-floor traders/brokers, but imagine if all shares in that market had to be traded in a single room, with no digital trading. It’s already quite lively on the trading floor today, now add all the trades from middle class Americans on payday. It would become physically impossible.

    Likewise, a pure capitalist stock market would permit awful things like bribing journalists to write fake stories to crash a stock, then buy it for cheap. Or pump and dump scams. And would have no “circuit breakers” that halt a share during so-called flash crashes.

    I’m reminded of a scene from the ITV show Agatha Christie’s Poirot in the episode “Appointment With Death”, where a wealthy woman is not only murdered but her business empire collapses because the murderer also spooks the markets as a double whammy, causing investors to panic and sell up. The relevant implications here is that despite her company not having changed its financial picture, it got cut up for scrap and thus lost most of its value, rendering the business worthless in the end. Companies are usually valued more as a going-concern, above what all its property put together would amount to. Where does that additional value come from? It’s the prospect of a return from this particular assemblage of resources.

    Suffice it to say, the stock market is a lot of things. But I view it as a natural result of certain other prerequisites, meaning we can’t really get rid of it, so instead it should be appropriately regulated.


  • At its very core, an insurance company operates by: 1) pooling policyholder’s risks together and 2) collecting premiums from the policyholders based on actuarial data, to pay claims and maybe make a small profit. But looking broader, an insurance market exists when: a) policyholders voluntarily or are obliged to obtain policies, b) insurers are willing and able to accept the risks in exchange for a premium expected to support the insurance pool, and c) the actuarial risks are calculable and prove true, on average.

    The loss of any of A, B, or C will substantially impact a healthy insurance market, or can prevent the insurance market from ever getting started. For some examples of market failures, the ongoing California homeowner insurance crisis shows how losing B (starting with insurers refusing to renew policies near the wildland-rural interface) and C (increase in insured losses due to climate change) results in policies becoming unaffordable or impossible to obtain.

    As a broader nationwide example, an established business sector that operates wholly without insurance availability is cannabis. A majority of US States have decriminalized marijuana for medical use, and a near-majority have legalized recreational consumption. Yet due to unyielding federal law, no insurer will issue policies for marijuana businesses, to protect from risks that any business would face, such as losses from fire, due to a product recall or product liability, or for liability to employees. These risks are calculable and there’s a clear need for such policies – thus meeting criteria A and C – but no commercial insurer is willing to issue. Accordingly, the formal market for cannabis business insurance is virtually non-existent in the USA.

    With these examples, we can see that the automobile insurance market meets all three criteria for a healthy market, but it’s how these criteria are met which is noteworthy. Motorists in the USA are obliged to insure in every state except New Hampshire and Virginia: it is a criminal offense to drive a car without third-party liability insurance, meaning the motorist might spend time in jail. Note: NH and VA won’t send a motorist to jail, but they do have administrative penalties for driving without “financial responsibility”, which includes insurance or a bond at the DMV.

    The exact requirement varies per state, with some requiring very low amounts of coverage and others requiring extra coverage like Personal Injury Protection (PIP, aka no-fault insurance). The point is that criteria A is easily met: motorists want to avoid jail, but also want to avoid the indignity of being sued after having caused a road incident, in addition to protecting their apparently only viable mode of transportation.

    Insurers can take into account the overall trends in national risks trends for automobiles (eg new car safety, through the Insurance Institute for Highway Safety, IIHS) as well as local or hyper-local risks (eg hail damage in the southeast, property crime in a particular zip code). And as a large country with nearly as many cars as people, many insurers are willing to meet the demand. This satisfies criteria B and C.

    So well-organized is the automobile insurance market that you could almost say that it’s vertically integrated: the largest nationwide insurers have contracts in place with every dealership network, auto collision chain, new and used parts dealers, as well as automatic data sharing with state DMVs, plus with firms like CarFax that buy information. Despite each state being slightly different, the insurers have overcome and achieved a level of near uniformity that allows an efficient market to exist.

    Things are drastically different for the American healthcare system and for American health insurance companies. While most think of their healthcare provider as a national name like Anthem Blue Cross or Kaiser Permanente, the reality is that each state is an island, and sometimes counties in a state are enclaves. Even federal programs like Medicaid and Medicare are subject to state-level non-uniformities. For example, hospitals can be either privately operated (eg religion-affiliated, or for-profit) or run by a public entity (eg county or state), and can exist as a single entity or form part of a regional hospital network. Some entities operate both the insurance pool as well as providing the health care (eg HMOs like Kaiser Permanente) while others dispatch to a list of contracted providers, usually being doctor’s own private practices or specialist offices.

    With so many disparate entities, and where healthcare is a heavily-regulated activity by each state, the cost of insurable risks – that is, for routine healthcare services – is already kinda difficult to compute. Hospitals and doctors go through intense negotiations with insurers to come to an agreement on reimbursement rates, but the reality is that neither has sufficient actuarial data to price based on what can be borne by the market. So they just pass their costs on, whatever those may be, and insurers either accept it into their calculations, or drop the provider.

    Suffice it to say, there are fewer pressure to push the total cost of healthcare down, given this reality, and more likely prices will continue to climb. This fails criteria C.

    financial flow in the US healthcare system Source

    Briefly speaking, it’s fairly self explanatory why people would want health insurance, since the alternative is either death or serious health repercussions, paying out-of-pocket rates for service, or going to the ER and being burdened by medical debt that will somehow haunt even after death. Criteria A is present.

    As for Criteria B, that was actually resolved as part of the Affordable Care Act (ACA). During discussions with the drafters, insurers bargained for an obligation for everyone to have insurance (aka the individual mandate, bolstering criteria A), in exchange for an obligation to issue policies for anyone who applies, irrespective of pre-existing health conditions. Thus, Criteria B is present for all ACA-compliant policies in the USA, even though the individual mandate was later legislatively repealed.

    So to answer your question directly, the costs for healthcare in the USA continue to spiral so far out of control that it causes distortions in the health insurance market, to everyone’s detriment. Specific issues such as open-enrollment periods, employer subsidies, and incomprehensible coverage levels all stem from – and are attempts to reduce – costs.

    Enrollment periods prevent people from changing plans immediately after obtaining an expensive service, like a major surgery. Employer subsidies exist due to a federal tax quirk decades ago, which has now accidentally become an essential part of the health insurance and health care situation. And coverage levels try to provide tiered plans, so people can still afford minimal coverage for “catastrophic” injuries while others can buy coverage for known, recurring medical needs.

    But these are all bandaging the bleeding which is unchecked costs. It would take an act of Congress – literally – or of state legislatures to address the structural issues at play. The most prominent solution to nip costs is the bud is to achieve the same near-vertical integration as with automobile insurance. This means a single or very few entities which have contracts in place with every provider (doctors and hospitals), negotiated at once and uniformly, so as to achieve criteria C. The single-payer model – which Medicare already uses – is one such solution.

    Going further would be the universal healthcare model, which discards the notion of health insurance entirely and creates an obligation for a government department to provide for the health of the citizens, funded by taxes. This means doctors and hospitals work at the behest of the department for the citizenry, or work privately outside the system entirely, with no guarantee of a steady stream of work. Substantial administrative savings would arise, since the number of players has been reduced and thus simplifies things, including the basic act of billing and getting paid for services rendered.

    These models could be approached by individual states or by the nation as a whole, but it’s unclear where the Overton window for that idea currently is.


  • It’s a straightforward question with a not-so-straightforward answer. I’m not any sort of lawyer, but I will borrow the classic lawyer answer of: “It Depends”.

    To start, the question of legalizing cannabis – meaning its sale, distribution, and consumption is as easy as for any other good – is distinct from the question of decriminalizing cannabis, which means it’s not a criminal offense to grow, sell, or consume.

    Right off the bat, we can say that the US President cannot fully legalize cannabis nationwide with the stroke of a pen, because the several states can (and already do?) have their own laws and regulations on cannabis and other drugs, parallel to the federal laws. But decriminalization is feasible, since the federal statues that criminalize cannabis are based on the drug schedules, which are regulations issued by DEA pursuant to authority granted by Congress. And that matters because most drug defendants are prosecuted under federal law.

    Of course, the several states could start writing their own laws to criminalize cannabis, but that would be kinda weird since the majority of states already allow medical marijuana, and a fair number allow recreational marijuana. So re-criminalizing cannabis would repeal those rather popular laws.

    So we move to how the DEA can amend the drug schedules, or how the US President can instruct the DEA Administrator. Because Congress is the grantor of such authority to the DEA and other executive agencies, and seeking to prevent regulations from whimsically flip-flopping with the passing breeze, Congress introduced the Administrative Procedures Act (APA) in 1946.

    As the name suggests, the Act sets up the rules for how regulations issued by agencies shall be performed. Most of the rules mirror those of Congressional procedure, meaning that the agency must conduct hearings on proposed rule changes openly, with the opportunity for the public to submit comments. That is, regulations suddenly appearing from behind closed doors is not permitted.

    Part of the rules require fixed timelines, such as a number of days for sending in comments, plus a number of days for publishing the full text of the proposed rule into the Federal Register, before the rule can become active.

    Furthermore, the Act instructs the judiciary to review regulations if someone raises a challenge to the adopted regulation. Among the things the judiciary will look at is whether the regulation is improperly “arbitrary and capricious”, meaning the regulation was pretextual and is instead serving a goal outside of what Congress intended for the agency to be doing. That link describes some examples deemed to be impermissible.

    If the US President issued a brief, non-explanatory executive order to remove cannabis from the drug schedules, thus shortcutting the rulemaking procedure and the period for public comment, a court challenge could arise where someone claims the regulation is arbitrary and capricious, since Congress would have expected the DEA to do a full, extensive job of considering the implications of drug availability. If the executive order does not do a similarly extensive consideration of what the DEA staff would do, then the court challenge would stand a decent chance. To be clear, the regulation via executive order would be struck down on procedural grounds, per the APA.

    What if instead, the US President sternly instructs the DEA Administrator to immediately consider descheduling cannabis? This is more likely to withstand challenge, since the DEA staff would go through their normal evaluation procedure, even if it’s at an expedited rate. Thoroughness is one way to avoid being struck for arbitrary-and-capriciousness.

    But there’s still a wrinkle, due to the recent demise of Chevron Deference, a doctrine where federal courts generally defer to the subject-matter experts within an executive agency if the enabling law was silent, so long as the APA’s other requirements were met. This leads to the weird possibility that a federal judge – who is unlikely to be well-versed in drug and social implications – can substitute the learned opinion of doctors and scientists within DEA with their own judicial opinion. If this sounds similar to the very arbitrary-and-capricious issue from earlier, you’d be right: a single person – in the judiciary, no less – writing regulations for drug policy is hardly what Congress intended in authoring the Controlled Substance Act in the 70s.

    The overall answer is that the US President has significant sway over the DEA Administrator and can expedite the rulemaking process to deschedule cannabis, thus decriminalizing it at the federal level. But even an un-expedited rulemaking process would attract legal challenges like flies to flypaper, slowing down when the regulation comes into force. And if a federal judge decides to do so, they can outright cancel the descheduling regulation, choosing to not defer to the DEA, even if the DEA articulated their reasoning well. While it would make logical sense that such a judge must have jurisdiction over DEA, which is headquartered in Washington DC, the reality is that federal agencies can be challenged in any federal court, including ones with, uh, very outspoken opinions on federalism.

    A more permanent change would be to decriminalize/legalize through Congress, since at that point, no future administration could roll that back. We’ve seen how fragile some rules or rulings can be, namely in the case of Roe v Wade being undone, as the decision was never codified into law, which would have made it much safer from judicial challenges.

    It really depends.



  • This article indicates that the USA FDA allows for up to a 20% margin of error for values required to be on the Nutrition Facts label. The article also describes multiple methods of measuring the calorific value of food, either by burning it in the not-so-TSA-friendly-named bomb calorimeter or through methods that have standardized the calorific value of each constituent nutrient.

    It’s also the case that not every foodstuff is perfectly identical to all other products. A banana is hardly going to be constituted exactly like another banana, and even the most basic measurement of mass will not match up to other bananas. Yet some sort of “standard” banana must be assumed in order to print the nutrition label.

    As an aside, I do fondly remember making a bomb calorimeter in chemistry class using a polystyrene cup as the insulation. It worked remarkably well, IIRC, being within 10% of what we were given as the expected value. Obviously, real measurements would be far more controlled than what some college freshmen can manage, but the concept is sound, if only measuring what the food provides, not necessarily what the human digestive tract can extract.

    As an aside to an aside, celery appears to not be a negative-calorie food, even after considering human digestion.


  • I live in a sunny climate (California), so I’m genuinely curious: would the solution to icy roads be winter tires? And does winter tire == snow tire?

    I understand studded tires are also an option, but I think their use in this state is heavily curtailed or outright prohibited because of the damage they inflict on the road surface.

    I don’t think I’d ever want to tackle ice in an automobile, although I’m told studded bicycle tires are very competent in winter and don’t have as many performance penalties as their car equivalent. I’d probably try that at least once in this lifetime.
