Encetem el 2026, un any en què tots els que, com jo, vam néixer el 1966, entrarem en una nova dècada de la nostra vida. Malauradament, l'11% dels membres d'aquella generació no han arribat a fer els 60 anys.

As a scientist and occasional baker, a pet peeve of mine are the recipes that require letting the dough raise until it doubles in volume. How am I supposed to measure the volume of that blob? At most, I can estimate that the vol. is 2X when the length has increased by the cubic root of 2, or 26%
