Every student of science, even if he cannot start his journey where his predecessors left off, can at least travel their beaten track more quickly than they could while they were clearing the way: and so before his race is run, he comes to virgin forest and becomes himself a pioneer.
Experimental work of great refinement is necessary in order to determine atomic weights. No relationships between them have yet been certainly found which make it possible for us to compute by any sort of calculation exactly the value of any one atomic weight from any other.
If our inconceivably ancient universe even had any beginning, the conditions determining that beginning must even now be engraved in the atomic weights.
