If we ascribe the ejection of the proton to a Compton recoil from a quantum of 52 x 106 electron volts, then the nitrogen recoil atom arising by a similar process should have an energy not greater than about 400, 000 volts, should produce not more than about 10, 000 ions, and have a range in the air at N.T.P. of about 1-3mm. Actually, some of the recoil atoms in nitrogen produce at least 30, 000 ions. In collaboration with Dr. Feather, I have observed the recoil atoms in an expansion chamber, and their range, estimated visually, was sometimes as much as 3mm. at N.T.P. These results, and others I have obtained in the course of the work, are very difficult to explain on the assumption that the radiation from beryllium is a quantum radiation, if energy and momentum are to be conserved in the collisions. The difficulties disappear, however, if it be assumed that the radiation consists of particles of mass 1 and charge 0, or neutrons. The capture of the a-particle by the Be9 nucleus may be supposed to result in the formation of a C12 nucleus and the emission of the neutron. From the energy relations of this process the velocity of the neutron emitted in the forward direction may well be about 3 x 109 cm. per sec. The collisions of this neutron with the atoms through which it passes give rise to the recoil atoms, and the observed energies of the recoil atoms are in fair agreement with this view. Moreover, I have observed that the protons ejected from hydrogen by the radiation emitted in the opposite direction to that of the exciting a-particle appear to have a much smaller range than those ejected by the forward radiation. This again receives a simple explanation on the neutron hypothesis.

James Chadwick
To regard all things and principles of things as inconstant modes or fashions has more and more become the tendency of modern thought. Let us begin with that which is without - our physical life. Fix upon it in one of its more exquisite intervals, the moment, for instance, of delicious recoil from the flood of water in summer heat. What is the whole physical life in that moment but a combination of natural elements to which science gives their names? But these elements, phosphorus and lime and delicate fibres, are present not in the human body alone: we detect them in places most remote from it. Our physical life is a perpetual motion of them - the passage of the blood, the wasting and repairing of the lenses of the eye, the modification of the tissues of the brain by every ray of light and sound - processes which science reduces to simpler and more elementary forces. Like the elements of which we are composed, the action of these forces extends beyond us; it rusts iron and ripens corn. Far out on every side of us those elements are broadcast, driven by many forces; and birth and gesture and death and the springing of violets from the grave are but a few out of ten thousand resultant combinations. That clear, perpetual outline of face and limb is but an image of ours, under which we group them - a design in a web, the actual threads of which pass out beyond it. This at least of flame-like our life has, that it is but the concurrence, renewed from moment to moment, of forces parting sooner or later on their ways.

Walter Pater
I'm really enjoying my solitude after feeling trapped by my family, friends and boyfriend. Just then I feel like making a resolution. A new year began six months ago but I feel like the time for change is now. No more whining about my pathetic life. I am going to change my life this very minute. Feeling as empowered as I felt when I read The Secret, I turn to reenter the hall. I know what I'll do! Instead of listing all the things I'm going to do from this moment on, I'm going to list all the things I'm never going to do! I've always been unconventional (too unconventional if you ask my parents but I'll save that account for later). I mentally begin to make my list of nevers. -I am never going to marry for money like Natasha just did. -I am never going to doubt my abilities again. -I am never going to... as I try to decide exactly what to resolve I spot an older lady wearing a bright red velvet churidar kurta. Yuck! I immediately know what my next resolution will be; I will never wear velvet. Even if it does become the most fashionable fabric ever (a highly unlikely phenomenon) I am quite enjoying my resolution making and am deciding what to resolve next when I notice Az and Raghav holding hands and smiling at each other. In that moment I know what my biggest resolve should be. -I will never have feelings for my best friend's boyfriend. Or for any friend's boyfriend, for that matter. That's four resolutions down. Six more to go? Why not? It is 2012, after all. If the world really does end this year, at least I'll go down knowing I completed ten resolutions. I don't need to look too far to find my next resolution. Standing a few centimetres away, looking extremely uncomfortable as Rags and Az get more oblivious of his existence, is Deepak. -I will never stay in a relationship with someone I don't love, I vow. Looking for inspiration for my next five resolutions, I try to observe everyone in the room. What catches my eye next is my cousin Mishka giggling uncontrollably while failing miserably at walking in a straight line. Why do people get completely trashed in public? It's just so embarrassing and totally not worth it when you're nursing a hangover the next day. I recoil as memories of a not so long ago night come rushing back to me. I still don't know exactly what happened that night but the fragments that I do remember go something like this; dropping my Blackberry in the loo, picking it up and wiping it with my new Mango dress, falling flat on my face in the middle of the club twice, breaking my Nine West heels, kissing an ugly stranger (Az insists he was a drug dealer but I think she just says that to freak me out) at the bar and throwing up on the Bandra-Worli sea link from Az's car. -I will never put myself in an embarrassing situation like that again. Ever. I usually vow to never drink so much when I'm lying in bed with a hangover the next day (just like 99% of the world) but this time I'm going to stick to my resolution. What should my next resolution be?
