Steampunk phonetics from the often interesting Languge Log. The early study of sound waveforms using phonauthgraphs.
We have seen that all sound, whether pleasant or unpleasant, whether music or mere noise, is represented by a curve. We shall first examine the general properties of such a curve, trying to discover why some curves produce pleasure when they reach our ears and some pain. We must then consider the transmission of sound, discussing how best to retain the pleasurable qualities in our sound-curve, as it passes on from one carrier to another, and how far it is possible to prevent unpleasant qualities contaminating the curve. Finally we shall have to discuss the strange transformations that the sound-curve may undergo inside our heads.
During the Victorian era there was a trend to popularize science with books, field guides and even amateur scientific instrumentation. Sea-side microscopy was one path.
A writer in the 1850s noted that "we appear to be on the eve of a microscope mania." In some instances, the microscope was "an indispensable aid to science." And in many instances it offered "an inexhaustible treasury of amusement to crowds of amateurs who aim no higher than to obtain a little useful information respecting the nature of the ordinary objects by which they are surrounded, and are content to admire beauty and variety of design, even when they cannot penetrate to final causes."
Two very different approaches were used for the bombs that destroyed Hiroshima and Nagasaki. There was a reason ... and why one survived.
During the cold war planners worried about the effects of bombs and tools were provided to interested citizens. Some have been updated. My high school chemistry teacher had a supply of circular slide rule bomb blast calculators. You can easily make a replica.
We knew the world would not be the same. A few people laughed, a few people cried, most people were silent. I remembered the line from the Hindu scripture, the Bhagavad-Gita. Vishnu is trying to persuade the Prince that he should do his duty, and to impress him takes impress him takes on his multi-armed form and says, "Now, I am become Death, the destroyer of wolds." I suppose we all thought that one way or another.
