43:0.3Eden­tia time reck­on­ing and dis­tance mea­sure­ment are those of Sal­ving­ton, and like the spheres of the uni­verse cap­i­tal, the con­stel­la­tion head­quar­ters worlds are fully sup­plied with all or­ders of ce­les­tial in­tel­li­gences. In gen­eral, these per­son­al­i­ties are not very dif­fer­ent from those de­scribed in con­nec­tion with the uni­verse ad­min­is­tra­tion.

46:1.2The stan­dard mile of Je­ru­sem is equiv­a­lent to about seven Uran­tia miles. The stan­dard weight, the “gradant,” is built up through the dec­i­mal sys­tem from the ma­ture ul­ti­ma­ton and rep­re­sents al­most ex­actly ten ounces of your weight. The Sa­ta­nia day equals three days of Uran­tia time, less one hour, four min­utes, and fif­teen sec­onds, that be­ing the time of the ax­ial rev­o­lu­tion of Je­ru­sem. The sys­tem year con­sists of one hun­dred Je­ru­sem days. The time of the sys­tem is broad­cast by the mas­ter chro­nol­deks.

65:6.1It is im­pos­si­ble ac­cu­rately to de­ter­mine, si­mul­ta­ne­ously, the ex­act lo­ca­tion and the ve­loc­ity of a mov­ing ob­ject; any at­tempt at mea­sure­ment of ei­ther in­evitably in­volves change in the other. The same sort of a para­dox con­fronts mor­tal man when he un­der­takes the chem­i­cal anal­y­sis of pro­to­plasm. The chemist can elu­ci­date the chem­istry of dead pro­to­plasm, but he can­not dis­cern ei­ther the phys­i­cal or­ga­ni­za­tion or the dy­namic per­for­mance of liv­ing pro­to­plasm. Ever will the sci­en­tist come nearer and nearer the se­crets of life, but never will he find them and for no other rea­son than that he must kill pro­to­plasm in or­der to an­a­lyze it. Dead pro­to­plasm weighs the same as liv­ing pro­to­plasm, but it is not the same.
