The Only Thing That Can

The Universe Is Asymmetric.

To Demonstrate Experimentally That A Microscopic Organism Actually Is The Cause Of A Disease And The Agent Of Contagion, I Know No Other Way, In The Present State Of Science, Than To Subject The Microbe (the New And Happy Term Introduced By M. Sédillot) To The Method Of Cultivation Out Of The Body.

Do Not Put Forward Anything That You Cannot Prove By Experimentation.

In That Memorable Year, 1822: Oersted, A Danish Physicist, Held In His Hands A Piece Of Copper Wire, Joined By Its Extremities To The Two Poles Of A Volta Pile. On His Table Was A Magnetized Needle On Its Pivot, And He Suddenly Saw (by Chance You Will Say, But Chance Only Favours The Mind Which Is Prepared) The Needle Move And Take Up A Position Quite Different From The One Assigned To It By Terrestrial Magnetism. A Wire Carrying An Electric Current Deviates A Magnetized Needle From Its Position. That, Gentlemen, Was The Birth Of The Modern Telegraph.

If It Is A Terrifying Thought That Life Is At The Mercy Of The Multiplication Of These Minute Bodies [microbes], It Is A Consoling Hope That Science Will Not Always Remain Powerless Before Such Enemies.
