Bohr, Kramers, and Slater: A Failed but Influential Attempt at Quantum Mechanics

In 1924, Niels Bohr, Hendrik Kramers, and John Slater proposed a radical theory of quantum radiation, attempting to resolve the crisis facing quantum mechanics at the time. The theory boldly hypothesized that the law of conservation of energy might not hold at the quantum level. Although quickly disproven by experiment, it reflected the prevailing confusion and exploration within the physics community regarding quantum mechanics, foreshadowing the long-standing debate between Bohr and Einstein over interpretations. The paper also touched upon the 'pilot-wave' idea, later becoming a significant interpretation of quantum mechanics (like the de Broglie-Bohm interpretation), leaving a unique mark on the history of quantum mechanics and spurring deeper exploration for understanding it.

Superbloom: How Connection Technologies Tear Us Apart

Nicholas Carr's new book, *Superbloom*, examines how modern connection technologies—cell phones, the internet, social media, etc.—impact individuals and society. Carr argues these technologies aren't inherently evil but cause negative consequences due to our misconceptions about communication and ourselves. He uses the 2019 Los Angeles poppy bloom event to illustrate how information overload and social media's amplification effect lead to chaos and negativity. The book traces the history of communication technologies, highlighting how they've always been accompanied by supernatural imaginings, and raises concerns about anonymity, power, and information veracity. Carr critiques technological optimism, arguing that information overload hasn't led to a more democratic or rational society but has instead exacerbated social divisions. He contends that social media's design leverages cognitive biases, exacerbating information fragmentation and fast-paced thinking, ultimately resulting in a 'hyperreality' where truth is indistinguishable from falsehood. Carr calls for a return to reality, resisting information overload, and proposes potential solutions, such as increasing the friction cost of information dissemination.
