Whistle-Blower Says Facebook Puts ‘Astronomical Profits Before People’
- Using her insider knowledge, Frances Haugen, a former Facebook product manager, testified at a Senate hearing about how the social network harms young people.
- She said the company needs to “declare moral bankruptcy.” Facebook pushed back on Twitter, saying she has “no direct knowledge of the topic.” Follow updates here.

專業數理這方面，諾貝爾物理學獎2021年的"科普解釋"，就很成功，背後的數學模式多很複雜，但是抓住"簡化"的要點。敬禮！
BREAKING NEWS
The Royal Swedish Academy of Sciences has decided to award the 2021 Nobel Prize in Physics “for groundbreaking contributions to our understanding of complex physical systems” with one half jointly to Syukuro Manabe and Klaus Hasselmann “for the physical modelling of Earth’s climate, quantifying variability and reliably predicting global warming” and the other half to Giorgio Parisi “for the discovery of the interplay of disorder and fluctuations in physical systems from atomic to planetary scales.”
The three laureates share this year’s Nobel Prize in Physics for their studies of chaotic and apparently random phenomena. Syukuro Manabe and Klaus Hasselmann laid the foundation of our knowledge of the Earth’s climate and how humanity influences it. Giorgio Parisi is rewarded for his revolutionary contributions to the theory of disordered materials and random processes.
Complex systems are characterised by randomness and disorder and are difficult to understand. This year’s prize recognises new methods for describing them and predicting their long-term behaviour.
One complex system of vital importance to humankind is Earth’s climate. Syukuro Manabe demonstrated how increased levels of carbon dioxide in the atmosphere lead to increased temperatures at the surface of the Earth. In the 1960s, he led the development of physical models of the Earth’s climate and was the first person to explore the interaction between radiation balance and the vertical transport of air masses. His work laid the foundation for the development of current climate models.
About ten years later, Klaus Hasselmann created a model that links together weather and climate, thus answering the question of why climate models can be reliable despite weather being changeable and chaotic. He also developed methods for identifying specific signals, fingerprints, that both natural phenomena and human activities imprint in the climate. His methods have been used to prove that the increased temperature in the atmosphere is due to human emissions of carbon dioxide.
Around 1980, Giorgio Parisi discovered hidden patterns in disordered complex materials. His discoveries are among the most important contributions to the theory of complex systems. They make it possible to understand and describe many different and apparently entirely random materials and phenomena, not only in physics but also in other, very different areas, such as mathematics, biology, neuroscience and machine learning.
“The discoveries being recognised this year demonstrate that our knowledge about the climate rests on a solid scientific foundation, based on a rigorous analysis of observations. This year’s laureates have all contributed to us gaining deeper insight into the properties and evolution of complex physical systems,” says Thors Hans Hansson, chair of the Nobel Committee for Physics.
