Ladd-Franklin's mathematical interests ultimately led her to make important contributions to the field of psychology. In 1886, she became interested in the geometrical relationship between binocular vision and points in space and published a paper on this topic in the first volume of the American Journal of Psychology the following year. During the 1891-92 academic year, Ladd-Franklin took advantage of her husband's sabbatical leave from Johns Hopkins and traveled to Europe to conduct research in color vision in the laboratories of George Müller (1850-1934) in Göttingen, and Herman von Helmholtz (1821-1894) in Berlin, where she also attended lectures by Arthur König. In contrast to the prevailing three-color and opponent-color explanations of color vision, Ladd-Franklin developed an evolutionary theory that posited three stages in the development of color vision. Presenting her work at the International Congress of Psychology in London in 1892, she argued that black-white vision was the most primitive stage, since it occurs under the greatest variety of conditions, including under very low illumination and at the extreme edges of the visual field. The color white, she theorized, later became differentiated into blue and yellow, with yellow ultimately differentiated into red-green vision. Ladd-Franklin's theory was well-received and remained influential for some years, and its emphasis on evolution is still valid today.
In a planned economy, the one that does their job of market forces in order to determine the outcome would be :
The government.
In this system, the Government control all the resource usage and distribution, leaving the private sector with almost no power.
Based on Morrison's version of the Hindenburg disaster, it can be said that his version of the event matches what is in the video for the most part. The only difference is the number of people on board.
<h3>Who was Herbert Morrison?</h3><h3 />
He was a reporter that covered the arrival of the Hindenburg to New Jersey and so was there when it caught flames and crashed to the ground, killing 35 people.
Morrison's version of the event were accurate because he saw it happen before his eyes. From the rain to the Hindenburg catching flames and then crashing after falling on its mooring mast.
The only difference is that Morrison thought the number of people on board were 106 when in fact they were 97 people.
