On this day: mastering mass and energy
175 feats from Galileo’s century to today: the days people learned to convert, move, contain, regulate and direct matter and energy. One memory card per month; every entry is dated to the day by a primary or institutional source.
Pick a month, turn the card
Each card holds every feat in that month, newest first, back to the oldest; the range on the card face reads the same way, newest–oldest. The coloured edge names the verb; the tag names what was being controlled. Read one card a day and ask the Socratic question: what limit did they hit, and what did they change to get past it?
- Convert — turn one form of matter or energy into another;60
- Move — carry mass or people across distance;56
- Contain — hold matter, heat or pressure where it belongs;13
- Regulate — keep a system at a set point — temperature, dose, power;25
- Direct — steer energy or motion to an exact target;21

How dates were checked
- Exact day or nothing. An entry is here only if a primary record or an institutional source (space agency, laboratory, museum, archive, patent office, Nobel or IEEE record, encyclopaedia) gives the day. Each card links that source. Candidates with only a month or year, or where good sources disagree on the day, were left out (17 dropped).
- Which calendar. Dates are Gregorian, as recorded where the event happened. Spaceflight dates follow the source, usually UTC; where the local date differs, the entry says so.
- What counts. A first or a record in controlling mass and energy: heat and cold, engines and electricity, flight and speed, materials and chemistry, fusion and particle physics, energy grids, and living systems. Weapons tests appear only where they marked a first release of nuclear energy (Trinity) or a national nuclear milestone (Pokhran).
- Verbs and objects. Convert, Move, Contain, Regulate and Direct are the course verbs; matter, heat, work/motion, fluids and living systems are the objects. Many feats fit more than one; each entry shows the main one.
- Found a wrong date? The dataset is open as JSON (month, day, year, title, why, verb, object, source). A correction should cite a primary source.
