The Reality of Angular Momentum Conservation in Physics: Debunking Misconceptions

Angular Momentum, often erroneously referred to as Angular Energy, is a fundamental concept in physics, particularly in the realm of rotational dynamics. As a respected SEO specializing in the field of physics, it is important to address the ongoing discussions surrounding the conservation of angular momentum. Despite some individuals, such as John Mandlbaur, attempting to promote misconceptions, the current scientific consensus is well-established and widely understood.

Conservation of Angular Momentum: A Fundamental Principle

Angular momentum is a conserved quantity in systems without external torques. This principle has been validated through numerous experiments and observations over the past three centuries. In a closed system, the total angular momentum remains constant. However, in open systems where external torques are present, such as those caused by friction, air drag, or wobble, angular momentum is not conserved. This is why the popular demonstration involving a ball-on-a-string, often favored by enthusiasts, does not demonstrate a violation of angular momentum conservation.

Let's consider a ball-on-a-string (BoA) demonstration. When there is no external energy input, the ball will eventually slow down and stop due to external torques. Reducing the radius by pulling the string increases the angular velocity, but this increase is due to the constant external torque, not a violation of conservation principles.()

Implications of Angular Momentum in Atomic Physics

The conservation of angular momentum plays a crucial role in explaining atomic spectra. It forms the basis for selection rules that determine branching ratios and fit very well with observed spectral weights. This principle is not just abstract but has practical applications in spectroscopy and quantum mechanics, making it a cornerstone in modern physics.

John Mandlbaur and His Misconceptions

John Mandlbaur, also known as Angular Energy, has garnered attention by promoting the idea that angular momentum is not conserved. However, such claims are contradicted by fundamental principles in physics. Mandlbaur is a university dropout who admits to lacking knowledge in both mathematics and physics, which makes his arguments particularly concerning. His writings, often presented as papers, are riddled with inaccuracies and unsupported claims.

Historical and Methodological Debacles

Mandlbaur's arguments are not supported by empirical evidence or proper methodologies. He has never conducted experiments with the necessary methodology and uncertainties, yet he criticizes others for not having done so. His claim that angular momentum is not conserved but rotational energy (which he calls Angular Energy) is conserved is particularly misleading. Rotational energy is the first-order integral of angular momentum, making the distinction between the two concepts meaningless in this context.

Theoretical and Practical Implications

Mandlbaur's assertions have far-reaching implications. If angular momentum were not conserved, it would effectively collapse almost all of classical physics, which has been extensively tested and validated over many decades. This is a testament to the robustness and reliability of the physical theories that describe our universe.

Mandlbaur's claims are not taken seriously by the scientific community. Rather than engaging in productive debate, his arguments are often met with amusement, given his history of cherry-picking data and making unsubstantiated claims. His insistence on disproving established physics through simple kitchen demonstrations is a clear indication of his self-confidence and arrogance.

Conclusion

The conservation of angular momentum is a well-established principle in physics, validated through rigorous experiments and theoretical frameworks. Claims suggesting otherwise, such as those propagated by individuals like John Mandlbaur, are at odds with the scientific consensus and are not supported by credible evidence. It is essential for the advancement of science to base discussions on accurate and well-substantiated principles, rather than misleading or unsupported claims.
