A preliminary report to the U. S. Congress on a portion of the subversive activities conducted by two specific Neo-Fascist organizations that espouse racial hatred and un-Democratic positions then at work in the United States. - Summary by KevinS

Talking about viewing the Ocean "If I take the attitude of appreciation, it would be absurd to say that this wave is composed of chemical elements which I do not see; and if I take the attitude of physical explanation, it would be equally absurd to deny that such elements are all of which the wave is made. From the one standpoint, the ocean is really excited; from the other standpoint, the molecules are moving according to the laws of hydrodynamics. If I want to understand the meaning of this scene every reminiscence of physics will lead me astray; if I want to calculate the movement of my boat, physics alone can help me".(from the Introduction)

Thoroughly appalled and sickened by the rising numbers of white-on-black murders in the South since the beginning of Reconstruction, and by the unwillingness of local, state and federal governments to prosecute those who were responsible, Ida Bell Wells-Barnett wrote Southern Horrors, a pamphlet in which she exposed the horrible reality of lynchings to the rest of the nation and to the world. Wells explained, through case study, how the federal government's failure to intervene allowed Southern states...

This is a book in the "Understanding the Atom Series" from the Division of Technical Information, U. S. Atomic Energy Commission. The authors discuss topics of The Machinery of Inheritance, Mutations, Radiation, Dose and Consequences. - Summary by Larry Wilson

This is a short booklet on science fact commissioned by the U. S. Energy Research and Development Administration . It tells the story of the origins of nuclear physics in terms understandable to an audience with minimal technical background. What were the steps through history - the discoveries that built upon one another - from alchemy to chemistry, physics, astronomy, mathematics, and quantum mechanics, that led to our understanding and harnessing nuclear energy? Asimov was a great writer of both science fact and fiction who wrote or edited more than 500 books, published in 9 of the 10 major categories of the Dewey Decimal Classification.

The famous physicist Sir Isaac Newton lectured on optics from 1670 - 1672. He worked on the refraction of light into colored beams using prisms and discovered chromatic aberration. He also postulated the corpuscular form of light and an ether to transmit forces between the corpuscles. His "Opticks", first published 1704 contains his postulates about the topic. This is the fourth edition in English, from 1730, which Newton corrected from the third edition before his death.

This paper is an attempt to give the most accurate facts obtainable bearing upon the question of colored domestic service in Philadelphia.

This 1955 book by an acknowledged authority is an absorbing account of meteorology before the advent of weather satellites. “This is the lively account of the hair-raising experiences of the men who have probed by sea and air into the inner mysteries of the world’s most terrible storms…. Here is the first intimate revelation of what the human eye and the most modern radars see in the violent regions of the tropical vortex. The descriptions of the activities of these valiant scouts of the storms are taken from personal interviews with military flyers and weathermen who have risked their lives in the furious blasts in all parts of the hurricane...

The Outline of Science, Volume 1 was written specifically with the man-on-the-street in mind as the target audience. Covering scientific subjects ranging from astronomy to biology to elementary physics in clear, concise and easily understood prose, this popular science work is largely as relevant today as when first published in 1922. Special emphasis is given to the principles of biological adaptation and evolution, especially how they relate to the rise of the human species from lower orders. Also included are the basics of the (then) fairly new concept of relativity and its impact on emerging scientific theories...

Some chapters are devoted to the new applied sciences of electricity, telegraphy, and flying.
