    Potential violence != actual violence. The potential to commit violence can be reframed as strength. It's useful because it grants you negotiating leverage, regardless of whether y…

    > The most energy you can extract from any type of bomb would be if it was converted to energy at 100% efficiency. Under normal circumstances, a bomb's energy is endogenous. But in…

    To me, the distinction maps onto the Effectual vs Causal distinction. For some path "A to B", some people prefer to consider their present tools/resources (point A) and work forwar…

    I tend to frame this in terms of the Multi-Armed Bandit Problem. It's a trade-off between exploration vs exploitation. It's often impossible to predict beforehand which strategy is…

    The retiree example is intended to demonstrate that a wealth tax is inherently perverse, regardless of who is targeted. Savings are just deferred expenditure and debt is just exped…

    One benefit of markets is price-discovery. But if you're not participating in a market, determining price is akin to shaking a magic 8 ball. It assumes a Just Price, which is a heu…

    The point isn't "matrix multiplication != scalar multiplication". The point is "the process of evaluating a reducible expression inherently discards information about the original …

    I tend to think of multiplication as a transformation. "repeated additional" almost makes it sounds like we're merely telescoping an interval within a single dimension. Whereas "tr…

    Suppose your friend Alice arranges your wedding. You ask her to arrange the lawn chairs in an arrangement of 2 rows and 3 columns. But she misinterprets your request as 3 rows and …

    Bubbles are inductive. Arbitrage is anti-inductive.

    I think snarfy is expressing incredulity that meteorology doesn't already account for these types of emmissions. Analogously, suppose the headline had read > Water flows downhill. …

    A literal trigger is a lever that fires a gun. A figurative trigger is some event that sets in motion a cascade of events that occur in rapid succession. The root cause of firing a…

    Ideally, the mapping from object to image is injective. What you're proposing will lead to "hash collisions" aka blurriness, since each point in the object will bleed colors into n…

    I feel obliged to contextualize "Billionaires Build" on behalf of the unaware. Marc Andreesen published an essay "It's Time to Build" [0]. He claims that ostensibly, COVID-19 infli…
