  • This book is more about ancient history and the origins of religion than marijuana. It even touches on the philosophy of conciousness and linguistics. It reads like an extensive research paper or thesis (with footnotes on every page and an impressive bibliography). It took me a whole year to get through it all! Green Gold The Tree of Life: Marijuana in Magic and Religion quotes respected historians such as Mircea Eliade and famous authors such as Terrance McKenna. It has inspired me to read more into the history of religion. It is a very valueable resource for anyone interested in...

  • Information Theory, Evolution, and the Origin of Life presents a timely introduction to the use of information theory and coding theory in molecular biology. The genetical information system, because it is linear and digital, resembles the algorithmic language of computers. George Gamow pointed out that the application of Shannon’s information theory breaks genetics and molecular biology out of the descriptive mode into the quantitative mode, and Dr. Yockey develops this theme, discussing how information theory and coding theory can be applied to molecular biology....

  • The accompanying pages contain the unfinished Sketch of a Theory of Life by S. T. Coleridge. Everything that fell from the pen of that extraordinary man bore latent, as well as more obvious indications of genius, and of its inseparable concomitant--originality. To this general remark the present Essay is far from forming an exception.

  • Replication of DNA is essential for the propagation of life. It is somewhat surprising then that, despite the vital nature of this process, cellular organ-isms show a great deal of variety in the mechanisms that they employ to ensure appropriate genome duplication. This diversity is manifested along classical evolutionary lines, with distinct combinations of replicon architec-ture and replication proteins being found in the three domains of life: the Bacteria, the Eukarya and the Archaea.

  • VALENTIN TURCHIN presents in The Phenomenon of Science an evolutionary scheme of the universe—one that begins on the level of individual atoms and molecules, continues through the origin of life and the development of plants and animals, reaches the level of man and self-consciousness, and develops further in the intellectual creations of man, particularly in scientific knowledge. He does not see this development as a purposeful or preordained one, since he accepts entirely the Darwinian law of trial and error.

Local histories are yearly becoming more numerous. In few places is there more justification for one than here. I. The beauty of the scenery is not well known. This book should do something to vindicate its character. There is no need on this point to go back to the time of...

  • Isn’t it strange that the animal we used to be developed into the creature that we now are? How – and why – did human intelligence and culture evolve? How did we evolve minds, philosophies and technologies? And now that we have them, where are they taking us?

  • Having been invited to give an address before the Concord School of Philosophy this summer, upon some subject relating to the question of immortality there under discussion, it seemed a proper occasion for putting together the following thoughts on the origin of Man and his place in the universe. In dealing with the unknown, it is well to take one's start a long way within the limits of the known. The question of a future life is generally regarded as lying outside the range of legitimate scientific discussion.

  • A lifetime risk of melanoma development of 6% has been estimated. The risk is greatest before age 5 and next greatest between ages 5 and 10. Early detection of melanoma is difficult in these lesions because of the deep dermal or subcutaneous origin of primary melanoma and because of the large and varied surface of the nevus. Prophylactic excision early in life can be accomplished by staged removal with coverage by split-thickness skin grafts. Surgery cannot remove all at-risk nevus cells as some may penetrate into the muscles or central nervous system below the nevus. At present there are...
