    Euclid distinguishes the unit (VII, Def.1) and number -- a multitude composed of units -- (VII, Def.2). His definition of prime and composite numbers (VII, Def.11 and Def.13) clear…

    http://www.combinedfleet.com/economic.htm does a nice job of outlining how hilariously overmatched the IJN was in terms of naval production. In addition to that, the IJN didn't hav…

    While that might (or might not) mitigate one perverse incentive, there are lots more. It's important for policy proposals to take unintended consequences into account. What others …

    Have you thought out the perverse incentives your pay scheme would create?

    Samuel Eliot Morison wrote a definitive history of the naval war in the Pacific, so your memory is good! Ian Toll's new series is shorter, but also top notch and benefits from more…

    The fab I use has a minimum order size of 3. It's a bit more expensive, but double digit monies for three decently complex boards.

    It's not exactly equivalent, but I think the TDRS provides communication between different objects in space.

    Most households contain at least several poisons (and precursors to hazardous gasses as well) amongst their cleaning supplies.

    Fair enough. I suppose what I'm asking is whether it's possible to purchase a more modern CPU independently of a SOC and design my own single board computer built around that. Can …

    Are there any good sources of documentation for working with Arm chips? Like, a simple single board (or breadboard) computer?

    I'd support this if app developers were also required to release their apps on all the available stores and obey the policies of a particular store for users who obtain the app thr…

    Check out the Apollo 10 mission; they in fact did that as a rehearsal for the landing.

    #2 you could read, "[He] tells the sailor's story to the mistresses, because mistresses love stories", which does have a possessive genitive.

    One way I've done that in the past is asking explicit questions about the syntax, like: > "If filiae is nominative, how would you translate the sentence?" or > What cases could agr…

    That particular sentence is a really tough knot pedagogically too. As a teacher, you want a short simple sentence that includes a nominative, genitive, dative, accusative, and verb…

    To be sure, the normative way of winning kleos was victory, to whit Marathon and Platea. The Greeks also had very different rules awarding time for sea combat and land combat (root…

    That presumes a modern strategic intent, though, which was often absent from ancient warfare. If the mission of the Spartans was to secure kleos -- the only immortality the the Gre…

    Right - that argument, I'm suggesting, is way beyond most fourth graders even in its modern algebraic form. It relies on lots of algebraic techniques that aren't generally taught u…

    The author's take on V.18 is interesting. Clarke has the proposition here: https://mathcs.clarku.edu/~djoyce/java/elements/bookV/propV1... It's not three pages long in Clarke (nor …

    The approach you describe definitely does not work for all children. The vast majority (that I've taught) are better served by a scaffold of increasingly complex metaphors and defi…

    Well, I'd be curious what your first ten sentences to a group of, say, 11th graders would be about Newtonian gravitation, and how those would compare to what you'd say about the sa…

    Truth be told, I've never tried to use a gtk-based editor without a mouse. Which would you recommend? I'll try it out.
