"Photographs of two women were retouched so that each woman had large pupils in one photograph and small pupils in the other. Male subjects were shown eight different pairs of the photographs and were asked in which picture did the woman appear to be more sympathetic, selfish, happier, angrier and so on. When the question concerned a positive attribute, subjects tended to choose the woman with the large pupils; for a negative attribute, they tended to choose the small pupils."
"A comprehensive study by the Jet Propulsion Laboratory vigorously urges that a $1-billion program be launched to develop a new automobile engine for introduction by 1985 or sooner. After observing that the automobile will maintain its dominant role in personal transportation through the foreseeable future,' the study concludes that two engines, the gas turbine and the Stirling-cycle engine, promise significantly greater fuel economies than such widely discussed alternatives as the diesel engine, the Rankine (steam) engine,"
A 1975 pupil-perception experiment manipulated pupil size in photographs and found male subjects judged large-pupil images more positively and small-pupil images more negatively. The Jet Propulsion Laboratory recommends launching a $1-billion program to develop a new automobile engine for introduction by 1985, identifying gas-turbine and Stirling-cycle engines as promising alternatives to diesel, steam, all-electric, hybrid or improved Otto-cycle options. A fully developed gas-turbine could yield about 22 percent more miles per gallon than a maximally improved Otto-cycle fleet, while a Stirling engine could offer roughly a 35 percent improvement. A 1924 claim about transmuting mercury into gold by Professor Adolf Miethe is also mentioned.
