something that happens at a given place and time | structure where a wall or building narrows abruptly |
a phenomenon located at a single point in space-time; the fundamental observational entity in relativity theory | a plate makes an inked impression on a rubber-blanketed cylinder, which in turn transfers it to the paper |
a phenomenon that follows and is caused by some previous phenomenon | a natural consequence of development |
a special set of circumstances | a horizontal branch from the base of plant that produces new plants from buds at its tips |
| a compensating equivalent |
| the time at which something is supposed to begin |
