Korva rescues the ideas worth keeping from podcasts. Each one becomes a Card.
Could complex self-awareness expose humans to severe mental suffering while enjoyment of life keeps existence worth continuing?
The classic aerofoil lift story fails: nothing requires air particles traveling above and below a wing to reunite.
The hole at a nib’s split spreads force and stops a crack traveling farther, like a drilled aircraft crack.
That decorative heart-shaped hole in Waterman’s feed lets air enter as ink leaves, preventing the fountain pen from choking.
“Dust” can mean removing dust from something or adding dust to it. English made one verb do both.
Rayleigh instability explains why writing too quickly can choke older vacuum-chamber fountain pens: continuous flow breaks into droplets.
Parker made the Duofold famous with burnt-orange color and an airplane-drop stunt, not a new filling mechanism.
A 1920s Waterman compresses a rubber ink bag to expel ink, then uses vacuum to draw it back in.
An airplane’s ideal construction sounds impossible: a huge, heavy machine made of “gossamer whispers.”
Bernoulli and Newton are useful shorthand explanations, but designing an aerofoil is far more complicated than choosing between them.
Pencil leaves room for self-doubt and revision. Ink turns writing into a commitment that cannot easily be undone.
Lift comes from both mechanisms: angled wings deflect air downward, while faster airflow creates lower pressure.
A fountain pen’s feed absorbs excess ink into channels, stopping floods before ink reaches the page.
