Scientist Quotes

All vinyl polymers may be regarded as built from monomeric units containing a tertiary carbon atom.
If the chain symmetry is maintained in the crystal lattice, the possible occurrence of different space groups is considerably restricted.
If the polymer chain assumes a helicoidal conformation in the crystalline state, and if it does not contain asymmetric carbon atoms, it can be expected that either helices of the same sense, or, in equal ratio, helices of opposite sense are represented in the lattice.
In view of the experience I had acquired in the field of chemical industry, certain Italian government and industrial bodies entrusted me in 1938 with the task of instituting research and development studies on the production of synthetic rubber in Italy.
Aeroplanes interested me, and at the outbreak of the Second World War, I joined the RAF as a volunteer reservist. I took the opportunity of studying the books which the RAF made available for radio mechanics and looked forward to an interesting course in radio.
Apart from my work, my greatest pleasures have been mainly out-of-doors, and although I no longer ski, I greatly enjoy walking in the mountains and leading country rambles.

I was born and brought up near a village in Nottinghamshire and in my childhood enjoyed the freedom of the rather isolated country life. After the First World War, my father had bought a small farm, which became a marvelous playground for his five children.
In the past, radiation treatment planning has been a very lengthy procedure. Now, with the aid of CT therapy-planning computer programs, we can position the therapy beams automatically with precision in a few minutes.
On a farm, you can get very bored.
Some time ago, I investigated the possibility that a computer might be able to reconstruct a picture from sets of very accurate X-ray measurements taken through the body at a multitude of different angles.
The periods between my 11th and 18th years remain the most vivid in my memory because this was the time of my first attempts at experimentation, which might never have been made had I lived in the city. I made hazardous investigations of the principles of flight, launching myself from the tops of haystacks with a homemade glider.
