The -sigma^2/2 of Black-Scholes is sometimes read as a correction for discounting or risk aversion. This paper shows that it is Itô’s second-order term itself, measurable directly as the gap between mean and median──the ratio agrees with exp(sigma^2T/2) to 12 digits. No new theorem or law is claimed. Scope of this pape...

When the same expression appears, the two are taken to be saying the same thing. This paper shows that two derivations agreeing exactly at one point are off by a factor of 2 at the next──agreement is not evidence of a shared root. No new theorem or law is claimed. Scope of this paper (scope note): No new theorem or law...

Kelvin’s age of the Sun is taken to have failed because the calculation was wrong. This paper shows that both divisions are correct and only the estimate of the reservoir differs──one luminosity yielding two ages a factor of 1099.05 apart. No new theorem or law is claimed. Scope of this paper (scope note): No new theor...

A Lagrange multiplier is taken to be an auxiliary quantity that appears mid-calculation. This paper shows that the multiplier agrees digit for digit with an independently defined physical quantity──and that which quantity it becomes is decided by the constraint imposed. No new theorem or law is claimed. Scope of this p...

The isochronism of the cycloid is taken to be a lucky property of that curve. This paper shows that reversing the direction makes isochronism fix the curve uniquely──requiring T to be independent of h alone yields f'(y) proportional to 1/sqrt(y). No new theorem or law is claimed. Scope of this paper (scope note): No ne...

The Gibbs paradox is said to be the problem of an entropy that jumps discontinuously. This paper shows that the variable that jumps and the variable that is continuous are different ones──composition stays continuous down to 10^-6, and what jumps is distinguishability. No new theorem or law is claimed. Scope of this pa...

A road is thought to carry more the faster it runs. This paper shows that two states carry the same flow at speeds differing by 2.6180──and the maximum flow occurs at half the free-flow speed. No new theorem or law is claimed. Scope of this paper (scope note): No new theorem or law is claimed──the fundamental diagram o...

A theoretical floor is taken to be a fixed target. This paper shows that how much one asks for moves the floor itself──so “how many times the floor” is undetermined without stating the condition. No new theorem or law is claimed. Scope of this paper (scope note): No new theorem or law is claimed──osmotic pressure, the...

Drying falls into two periods, and the second is said to be the long one. This paper shows that which is longer switches with how dry one wants it──and the switch lies at a moisture content of 0.039506. No new theorem or law is claimed. Scope of this paper (scope note): No new theorem or law is claimed──the distinction...
