Matter and Antimatter - Maurice Duquesne - 1960

The reader might wonder why a work setting out to discuss the latest developments in nuclear physics should be called Matter and Antimatter. The reason is that the recent discovery of anti-protons and anti-neutrons, completing the list of antiparticles, has led physicists to coin the word 'antimatter . We shall be careful in our use of this word, if only to bring it down from the fantastic heights to which the. popular press has elevated it. On the whole, attempts at popularisation are laudable enough, but when it comes to modern physics they are fraught with danger. Here reality is often represented by mathematical equations beyond the reader's grasp, a fact which encourages many a sensationalist writer to indulge in fantasies. The current interest in anti-particles is by no means due to their novelty—their existence was predicted in a theoretical paper published as long ago as March 1930, and the first anti-particle (the positive electron) was observed and identified in 1933. At the time the news caused no stir outside the very narrow circle of specialists. Nowadays, the moment a new particle is identified, it is announced to the public, and despite the reserve of physicists, the popular press has no hesitation in pontificating about its unknown properties. Though not brand-new, therefore, the problem of anti-particles is nevertheless of great interest, no only because of the old questions it resolves but also because of the new questions it poses. The discovery of anti-protons and anti-neutrons has confirmed the general validity of the theory, presented by Dirac, a young English mathematician, to the Royal Society on the 6th December, 1929. Do anti-particles have the property of combining to form a negative anti-nucleus which, together with positive electrons would make up an anti-atom? Is this how we must conceive the structure of so-called antimatter? Inasmuch as so small a book can do justice to the labours of some of the greatest scientists of the past thirty years, I shall try to show what discoveries have led physicists to ask these and similar questions.

Are you informed we are in 2011 ?
A book about physic, written 50 years ago !
Physic now has completely change !
Sorry for you ...

niarlttep, some people may need exactly this information, and not the latest theories. Statement is a statement, even if its outdated.
