The Higgs Discovery Did Not Take Place

arg min • 1071 implied HN points • 22 Oct 24
🔬 Science Physics Statistics Quantum Mechanics Scientific Method
  1. The Higgs boson was theoretically discovered, but many people argue that this claim isn't solid due to complex statistical methods used in the research. It's not just about finding a particle; it's heavily based on probabilities.
  2. A lot of the processes in particle physics rely on trust within scientific communities and committees. They decide what counts as 'discovery' often through agreed conventions rather than direct proof.
  3. Questions about the Higgs boson reflect broader concerns in science regarding accountability. It shows that scientific findings often come down to people, their processes, and their decisions rather than just raw data.

  3. Many scientists who shaped quantum mechanics were caught between supporting the new ideas and adhering to older principles of causality, leading to mixed interpretations of their findings.

Philosophic Premises of Quantum Mechanics – Part II

Fields & Energy • 239 implied HN points • 19 Nov 23
🔬 Science Quantum Mechanics Philosophy Causality
  1. Quantum mechanics was influenced by ideas that questioned the existence of an objective reality. Some scientists believed that what we observe is just a statistical illusion rather than a definite state.
  2. Key figures like Heisenberg and Bohr argued against the law of causality, suggesting that atomic processes might not follow traditional cause-and-effect rules. They felt that understanding these processes could lead to contradictions.
  3. Attempts to create a causal theory in quantum mechanics faced strong opposition. Despite efforts from scientists like Schrödinger, the non-causal view became widely accepted due to its statistical predictions.
