Light, time and micro-organisms
The pts scale
There are four columns. The left-hand column is the pts scale itself, with t (s) values also given.
Throughout these pages, click on the left-hand column, the scale itself, to go to the introductory page for the chosen time domain. Alternatively, click on the right arrow at the foot of the page to move forward to the next time domain, or on the left arrow to move back to the previous one.
The second column places important processes along the pts scale at positions corresponding to their lifetimes, where these are known, or can be guessed with reasonable confidence. The third column is a similar arrangement of the events covered in this presentation.
The right-hand column "Data", is intended to provide points of reference. At positive values of pts, these are given as the distance travelled by light during the corresponding time interval.
