A Quote by Irene Joliot-Curie
It was at the beginning of 1934 while working on the emission of these positive electrons that we noticed a fundamental difference between that transmutation and all the others so far produced; all the reactions of nuclear chemistry induced were instantaneous phenomena, explosions.

We have shown that it is possible to create a radioactivity characterized by the emission of positive or negative electrons in boron and magnesium by bombardment with alpha rays.
Scheele, it was said, never forgot anything if it had to do with chemistry. He never forgot the look, the feel, the smell of a substance, or the way it was transformed in chemical reactions, never forgot anything he read, or was told, about the phenomena of chemistry. He seemed indifferent, or inattentive, to most things else, being wholly dedicated to his single passion, chemistry. It was this pure and passionate absorption in phenomena-noticing everything, forgetting nothing-that constituted Scheele's special strength.
Temptation, if it is not to conquer, must not fall like a bomb against another bomb of instantaneous moral explosions, but against the strong walls of an impregnable fortress strongly built up, stone by stone, beginning at that distant day when the foundations were first laid.
A Winner's Blueprint for Achievement BELIEVE while others are doubting. PLAN while others are playing. STUDY while others are sleeping. DECIDE while others are delaying. PREPARE while others are daydreaming. BEGIN while others are procrastinating. WORK while others are wishing. SAVE while others are wasting. LISTEN while others are talking. SMILE while others are frowning. COMMEND while others are criticizing. PERSIST while others are quitting.
The history of science can be viewed as the recasting of phenomena that were once thought to be accidents as phenomena that can be understood in terms of fundamental causes and principles.
Atoms consist of a positive nucleus and negative electrons flying around outside it. Electrons closest to the nucleus feel a strong negative-on-positive tug, and the bigger atoms get, the bigger the tug. In really big atoms, electrons whip around at speeds close to the speed of light.
Mothers know the difference between a broth and a consommé. And the difference between damask and chintz. And the difference between vinyl and Naugahyde. And the difference between a house and a home. And the difference between a romantic and a stalker. And the difference between a rock and a hard place.
Each emission of an alpha or beta ray accompanies the transmutation of an atom; the energy communicated to these rays comes from inside the atom.
I've always noticed a difference between working with a director and working with a writer/director. In how much they're invested and how specific they are.
Los Angeles people are incapable of passively mainlining TV and movies. Here you have to read who produced or directed every episode, who wrote it, who had guests shots and whether you know them personally and if they like you. You have to figure out who everybody's agent is and whether yours is better. You not only know but deeply care about the difference between such job titles as Producer, Supervising Producer, and Executive Story Editor. ... So while the rest of the country is lying stupid in a media-induced coma, people in L.A. are in constant withdrawal.
I became almost immediately fascinated by the possibilities of trying out all conceivable reactions with them, some leading to explosions, others to unbearable poisoning of the air in our house, frightening my parents.
If you had to sum up chemistry in one sentence, it might be this: Atoms need to have full shells of electrons to feel satisfied, and different elements steal, shed, or borrow different numbers of electrons to achieve a full shell.
We must remember that there is a great difference between a myth and a miracle. A myth is the idealization of a fact. A miracle is the counterfeit of a fact. There is the same difference between a myth and a miracle that there is between fiction and falsehood -- between poetry and perjury. Miracles belong to the far past and the far future. The little line of sand, called the present, between the seas, belongs to common sense to the natural.
There's a difference between good chemistry and a bond. Chemistry is something you have with somebody you meet - or you don't. It's an intangible. It may be superficial. It's much harder to put your finger on than a bond.
In 1934, the American Jewish charities offered to find homes for 300 German refugee children. We were on the SS Washington, bound for New York, Christmas 1934.
I always had good reactions from people with a good eye and a vision... and very terrible reactions from those who are afraid of people who are different to others - at the beginning and even now. I have never worried about it too much.
