Revolutionary Breakthrough Challenges 300-Year-Old Physics Law

A philosopher of language and mathematics, Daniel Hoek, suggests that the original 1729 English translation of Newton's first law of motion contains a mistranslation of the Latin word 'quatenus,' which should be read as 'insofar' rather than 'unless.' This reinterpretation implies that every change in an object's momentum is due to external forces, aligning more closely with Newton's original intent and emphasizing that all physical bodies, including celestial ones, are governed by the same laws. Despite its significance, this correction has not gained widespread acceptance.

Internet Debunks Magnet Truck's Viability

A person invited the internet to give one good reason why a magnet truck wouldn't work, but the laws of physics provide several reasons. The magnet truck would violate fundamental laws such as Newton's First Law of Motion and Newton's Third Law of Motion. The magnet and the truck are part of the same system, canceling out any force and resulting in no propulsion. The idea of using a magnet to power a vehicle is not feasible and would create a perpetual motion machine, which is not possible according to the laws of physics.

"Sperm Defies Laws of Physics, Baffling Scientists"

Scientists at Kyoto University have discovered that sperm can defy Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. The researchers found that the flagella on sperm have an "odd elasticity" that allows them to whip around without losing much energy to the fluid, enabling the cells to propel themselves through viscous fluids. This discovery could have implications for designing self-assembling robots and understanding collective behavior.

Sperm Cells Defy Newton's Laws: Scientists Uncover the Mystery

Scientists at Kyoto University have discovered that sperm defy one of Newton's laws of physics by propelling themselves forward through fluid without eliciting an equal and opposite reaction. The sperm's flagella, or tails, change shape to interact with the fluid, allowing them to move without expending much energy. This movement method, known as "odd elasticity," contradicts Newton's law of motion. The researchers used human sperm cells and algae for their study, observing how the flagella deformed and returned to their original shape to propel the swimmers through the liquid.

"Breakthrough: 12,000 New Solutions Found for the Three-Body Problem"

Researchers from Sofia University in Bulgaria have reported 12,409 orbital patterns for three-body systems that adhere to Newton's laws and have equal masses. While these solutions have not yet been peer-reviewed, they provide valuable insights into the three-body problem. However, most of these solutions have limited real-world applications due to their reliance on precise initial conditions. Nevertheless, the study contributes to the ongoing search for mathematical solutions to explain the stable dance of three celestial bodies and may have potential astronomical relevance if the stability of the solutions is considered in the presence of external influences.
