| The lightning came, in one of those broad, sheetlike flickers that seem to irradiate the world for countable seconds. |
| Mathematicians divide infinite sets into two categories, countable and uncountable sets. |
| Thus, 100 countable individuals was a targeted minimum that was easily surpassed in many samples but not achieved in others. |
| This then becomes the divisor to determine the piece count from the weight of an unknown quantity of countable parts. |
| A full hierarchical perspective suggests a continuum of variation rather than a countable number of objects. |
| The optimum fibre density should give an average of about one or two countable fibre per fields of view at 5 000 magnification. |
