Einstein's First Steps Toward General Relativity: Gedanken Experiments and Axiomatics

AlbertEinstein's 1907 Jahrbuch paper is an extraordinary document because it contains his first steps toward generalizing the 1905 relativity theory to include gravitation. Ignoring the apparent experimental disconfirmation of the 1905 relativity theory and his unsuccessful attempts to generalize the mass-energy equivalence, Einstein boldly raises the mass-energy equivalence to an axiom, invokes equality between gravitational and inertial masses, and then postulates the equivalence between a uniform gravitational field and an oppositely directed constant acceleration, the equivalence principle. How did this come about? What is at issue is scientific creativity. This necessitates broadening historical analysis to include aspects of cognitive science such as the role of visual imagery in Einstein's thinking, and the relation between conscious and unconscious modes of thought in problem solving. This method reveals the catalysts that sparked a Gedanken experiment that occurred to Einstein while working on the Jahrbuch paper. A mental model is presented to further explore Einstein's profound scientific discovery.

Memorial Tributes: Volume 25 (2023)
1937–2018
Elected in 2000
“For contributions to Taiwanese electronics industry, education, and materials technology.”
BY MIN-CHIUAN WANG
SUBMITTED BY THE NAE HOME SECRETARY
CHUN-YEN CHANG, who created Taiwan’s first integrated circuit and is known as the country’s semiconductor pioneer, died October 12, 2018, on his 81st birthday.
He was born October 12, 1937, in the Fengshan District of Kaohsiung, a city in southern Taiwan, during the Japanese occupation. His father, Mu-Huo Chang, was a farmer who relied on his own efforts to become a teacher at Fengshan Elementary School and later at Kaohsiung Middle School; his mother, Shu-Yu Cheng, was the daughter of a rich family in Fengshan. Chun-Yen had five siblings.
The first 10 years of childhood were happy for Chun-Yen Chang. That changed in 1947 with the February 28th Incident in Taiwan. His father was arrested and, although lucky enough to be released, lost his position as a high school teacher. The Chang family moved to Gushan in Kaohsiung, where his father made a living selling timber. Later the family moved to Madou District in Tainan City, where Chun-Yen finished his schooling. Because of the war and political turmoil, the boy attended seven s
