If that is of no avail I will take another, and yet another.

如果那没有用，我会再拿一个，再拿一个。

The steam engine, the telegraph, the telephone, the trolley car, dyestuffs, medicines, explosives — these are the fruits of science, and without these science is of no avail.

蒸汽机、电报、电话、电车、染料、药物、炸药——这些都是科学的成果，没有这些科学就没有用。
