Science knows no country, because knowledge belongs to humanity, and is the torch which illuminates the world.

Change only favours minds that are diligently looking and preparing for discovery.

The grandeur of the acts of men are measured by the inspiration from which they spring.

The controls of life are structured as forms and nuclear arrangements, in a relation with the motions of the universe.

I propose to provide proof... that just as always an alcoholic ferment, the yeast of beer, is found where sugar is converted into alcohol and carbonic acid, so always a special ferment, a lactic yeast, is found where sugar is transformed into lactic acid. And, furthermore, when any plastic nitrogenated substance is able to transform sugar into that acid, the reason is that it is a suitable nutrient for the growth of the [lactic] ferment.

Science knows no country, because knowledge belongs to humanity, and is the torch which illuminates the world. Science is the highest personification of the nation because that nation will remain the first which carries the furthest the works of thought and intelligence.

Do not put forward anything that you cannot prove by experimentation.
