Caffeine blocks adenosine receptors, so sleep pressure is masked rather than removed.
Half-life is about 5 hours, so a 4 pm coffee still leaves half the dose at 9 pm.
Moderate doses (about 100 mg) improve reaction time; above 400 mg per day anxiety rises.
Personal rule: no coffee after 1 pm on days before an experiment.

Newport defines deep work as distraction-free concentration that pushes your abilities.

Attendees: Priya, Tomas, Nare.
Decision: run the nap study with 24 participants instead of 16, budget approved by Priya.
Action: Tomas books the sleep lab for the weeks of 5 and 12 October.
Action: Nare drafts the consent form by 15 September.
Risk: EEG caps are shared with another group, so booking conflicts are likely.

Work for 25 minutes, then take a 5 minute break; after four rounds take a longer 20 minute break.
Works well for writing and reading papers, badly for debugging where context switching is costly.

Slow-wave sleep replays the day's hippocampal activity and moves it into long-term cortical storage.
Walker (2017) reports that a night without sleep cuts new memory formation by about 40 percent.
A 20 minute nap after learning helps recall of word pairs, but only if the nap reaches stage 2 sleep.

Reviewing material at growing intervals (1 day, 3 days, 7 days, 21 days) beats massed study.
The forgetting curve from Ebbinghaus drops fastest in the first 24 hours after learning.
Anki uses the SM-2 algorithm; FSRS is a newer scheduler that predicts recall probability.
