Are Humans "Omnivores"?

By John Coleman, 2008 Introduction by John Coleman It is not unusual to hear the claim that humans are "omnivores", even authoritative text books and research papers use this term. Unfortunately the meaning of this term is somewhat vague. On the one hand, the term omnivore can simply be used to describe animals that eat plant or animal foods, and on the other, it may be used to infer that an animal is biologically adapted to consume both plant and animal foods, and perhaps, that it is supposed to do so. A broader, and perhaps more appropriate definition of an omnivore, would refer to animals than can consume all kinds of food. This is because omni derives from the latin omnis meaning all. Therefore, in common use, the term omnivore may be used to describe both a) what an animal does and b) what an animal is. Clearly humans are omnivores in the sense that they do eat both plant and animal foods. As an example of the contrast between is and does, cattle consume animal remains i...

Relativity: The Special and General Theory

Albert Einstein Preface in this eBook : The present book is intended, as far as possible, to give an exact insight into the theory of Relativity to those readers who, from a general scientific and philosophical point of view, are interested in the theory, but who are not conversant with the mathematical apparatus of theoretical physics. The work presumes a standard of education corresponding to that of a university matriculation examination, and, despite the shortness of the book, a fair amount of patience and force of will on the part of the reader. The author has spared himself no pains in his endeavour to present the main ideas in the simplest and most intelligible form, and on the whole, in the sequence and connection in which they actually originated. In the interest of clearness, it appeared to me inevitable that I should repeat myself frequently, without paying the slightest attention to the elegance of the presentation. I adhered scrupulously to the precept of that brilliant th...
