Absalon Larsen and H.C. Ørsted - 1820 1920 2020

Back in 1920 the text inside this book was issued as a tribute to the Danish physicist H.C. Ørsted and the 100th anniversary of his discovery of electromagnetism in 1820. In this version, the 2020 version, while we acknowledge the crucial importance of H.C. Ørsted, we are paying tribute to the relatively unknown author of the 1920 preface: Absalon Larsen.
Søren Absalon Larsen (1871-1957) was a Danish physicist who worked in the field of electroacoustics. He was the first in the world to describe acoustic feedback (around 1910) – hence the name Larsen Effect which describes the sonic phenomena of acoustic feedback which occurs when a sound loop exists between an audio input and an audio output.
Even though feedback originated in the world of sound and physics, the concept has had a rich history within a wide array of scientific fields, such as philosophy, communication theories, biology and most important within climate research. The concept of feedback offers insights into the complex relationship between man and the surrounding world, changing the concept of nature and ourselves right in the middle of the 6th mass extinction.
