Or maybe you're misguided? You seem to want to expound a fairly naive Popperian view of science, but cannot distinguish "proposition" from "hypothesis".

There are sentences that are not propositions, for example "Go get me a beer", or "Will it rain?" or "Greenness perambulates."

That's the crucial point. You can have a super high entropy probability distribution straight from a quantum lava lamp, but if it gives you "hunter2" as a password, you should still not use that password, no matter the entrop

For high-dimensional spheres, most of the volume is in the "shell", ie near the boundary [0]. This sort of makes sense to me, but I don't know how to square that with the observation in the article that most of the surface ar

Gambling addiction also has the highest suicide rate among addictions, so definitely serious. The Atlantic had an article recently arguing that allowing sport gambling in the USA was a mistake, imposing huge costs on the most vulnerable.

The word “Presumably” is doing a lot of heavy lifting there. That Econ101 justification is harder and harder to keep up as you learn more about both economics and the real world. For detailed counter arguments, see Branko Milanović Global

By put-call parity, C - P = S - df K, thus C = S - df K + P > S - K. This is contingent only on the discount factor df being <= 1, and P >= 0, which is basically always the case. Thus, the value of the call exceeds the exercise val

Generally, you back out local vols (as a function of S, t) of the BS vols (as a function of K, T) by a process described first by Dupire, and then you price American options (and other products that are not sensitive to vol of vol) with tha

Well, yes. If you buy a stock with positive drift and hold it, the model predicts "infinite growth" (in the sense that for any number N you give me I can give you a time t at which the E[S(t)] > N). But it might take quite some

In a sense, BS and the option market enable trading in volatility itself. Specifically, you trade in the estimate of the stock's volatility over the time from now to expiry of the option. If you don't want to trade options directl

European and American calls cost the same on non-dividend paying stocks (on dividend paying stocks, it might make sense to exercise an American just before the ex-date). Either way, as was pointed out, in reality BS is used as a determinist

A few points: 1) Very nice exposition. 2) Near eq. (4) it is claimed that one cannot compute the delta \frac{\del C}{\del S} without stochastic calculus, since S is stochastic. That doesn't strike me as correct: C is just a determinist

The introduction of blockchain does not strengthen, or replace, the rule of law; it weakens it. Do you think that the fact that the Yahoo boys in Nigeria and the Black Axe in Nigeria are getting rich with crypto scams contributes positively

Some ad-hoc feedback on [4]: - You don't explain that BFT in SMR is also a property of pre-blockchain 1990's permissioned systems such as PBFT or (Byzantine) Paxos. You don't distinguish between LCR + PoW (Nakamoto consensus)
