I Was Taught The Method For Advancement

When One Studies Strongly Radioactive Substances Special Precautions Must Be Taken If One Wishes To Be Able To Take Delicate Measurements. The Various Objects Used In A Chemical Laboratory And Those Used In A Chemical Laboratory, And Those Which Serve For Experiments In Physics, Become Radioactive In A Short Time And Act Upon Photographic Plates Through Black Paper. Dust, The Air Of The Room, And One's Clothes All Become Radioactive.

The Sensitive Plate, The Gas Which Is Ionised, The Fluorescent Screen, Are In Reality Receivers, Into Another Kind Of Energy, Chemical Energy, Ionic Energy... Luminous Energy.

It Was Like A New World Opened To Me, The World Of Science, Which I Was At Last Permitted To Know In All Liberty.

Each Of Us Must Work For His Own Improvement, And At The Same Time Share A General Responsibility For All Humanity.

I Was Taught That The Way Of Progress Was Neither Swift Nor Easy.
