Why did Einstein tirelessly study unified field theory for more than 30 years? In this book, the
author argues that Einstein believed he could find a unified theory of all of nature's forces by …

In 1909, Einstein derived a formula for the mean square energy fluctuation in black-body
radiation. This formula is the sum of a wave term and a particle term. In a key contribution to …

A prominent way through which wave-particle duality has been ascribed to photons is by
illustrating their “wave-like” behaviour in the Mach-Zehnder interferometer and “particle-like” …

The Mach-Zehnder Interferometer (MZI) is used to illustrate the long-standing wave-particle
duality problem. How can the photon divide at the first beam splitter and yet terminate on …

It is little known that during the birth of quantum mechanics Walther Bothe (1891–1957)
published from mid-1923 to the end of 1926, partly together with Hans Geiger (1882–1945) …

2020 年初春, 天下大疫. 作者旬日足不出户, 遂有充裕时间翻阅黑体辐射的原始文献.
每念从来不事稼穑而能衣食无忧, 作者辄油然而生愧意. 黑体辐射问题研究 …

Poucos anos antes de suas mortes, o velho confidente de Albert Einstein, Michele Besso,
deve ter-lhe escrito uma carta referindo-se a ele, de sua forma tipicamente entusiasmada …

荷兰物理学家洛伦兹 (Hendrik Antoon Lorentz, 1853—1928, 图 18) 是近代物理的旗手 (所谓的
leading spirit), 对相对论有基础性的贡献 (电动力学, 洛伦兹变换), 为量子理论思想的接受准备了 …

The Mach-Zehnder Interferometer (MZI) is chosen to illustrate the long-standing wave
particle duality problem. Why is which-way (welcher weg) information incompatible with …

The historiography of quantum theory exhibits a period of intense activity that started in the
1960s, with the Archives for the History of Quantum Physics project, and continued with the …
