The PIGA was based on an accelerometer developed by Dr. Fritz Mueller, then of the Kreiselgeraete Company, for the LEV-3 and experimental SG-66 guidance system of the Nazi era German V2 (EMW A4) ballistic missile and was known among the German rocket scientists as the MMIA "Mueller Mechanical Integrating Accelerometer". This system used ...
In 1978, Phoebe-Lou Adams, in her review for The Atlantic, wrote: "only a confirmed pig-hater could resist this odd, pretty (yes, pretty) book."

an accelerometer, [3] a real time clock or timer to start/stop the actigraph recording at specific times, and to record accumulate values for a specific time frame, a non-volatile memory to store the resulting values, an optional low-pass filter which filters out everything except the 2–3 Hz band, thereby ensuring external vibrations are ...
A description of how a piezoelectric accelerometer works in theory. A piezoelectric accelerometer is an accelerometer that employs the piezoelectric effect of certain materials to measure dynamic changes in mechanical variables (e.g., acceleration, vibration, and mechanical shock).
Psychological Review is a bimonthly peer-reviewed academic journal that covers psychological theory.It was established by James Mark Baldwin (Princeton University) and James McKeen Cattell (Columbia University) in 1894 as a publication vehicle for psychologists not connected with the laboratory of G. Stanley Hall (Clark University), who often published in his American Journal of Psychology.
Vacuum activities (or vacuum behaviours) are innate fixed action patterns (FAPs) of animal behaviour that are performed in the absence of a sign stimulus (releaser [broken anchor]) that normally elicit them. [1]
PsycCRITIQUES was a database of reviews of books, videos, and popular films published by the American Psychological Association. It replaced the print journal Contemporary Psychology: APA Review of Books, which was published from 1956 to 2004. The official blog of PsycCRITIQUES allowed free access to the full text of some recent reviews. It was ...
The 2nd Edition of the book was published in 1998, with responses to new developments in the field, such as The Bell Curve which suggested racial differences in IQ and intelligence between races. [4] Even more crucial than the examination of racist academic work was the book's work cataloging the work and triumphs of early Black psychologists.
