What is an example of a thought experiment?

In the 17th century, Galileo used thought experiments to affirm his theories. One example is his thought experiment involving two balls (one heavy, one light) which are dropped from the Leaning Tower of Pisa. Prior philosophers had theorized the heavy ball would land first.

What was Schrödinger's most famous thought experiment?

Schrödinger's cat experiment is a famous thought experiment in quantum mechanics proposed by physicist Erwin Schrödinger in 1935. It illustrates the concept of superposition and the interpretation of quantum mechanics.

Top 10 Most Famous THOUGHT EXPERIMENTS

What did Einstein say about Schrodinger's cat?

According to quantum theory, the cat could be in a state of being both alive and dead until an observer opened the box and measured its state. Einstein argued that this was absurd, and that the cat's existence should not depend on the act of observation.

What does the 2 slit experiment prove?

In modern physics, the double-slit experiment demonstrates that light and matter can exhibit behavior associated with both classical particles and classical waves.

What is Einstein's thought experiment?

Einstein's thought experiments took diverse forms. In his youth, he mentally chased beams of light. For special relativity, he employed moving trains and flashes of lightning to explain his theory.

What is the last person thought experiment?

'The Last Man'1 is a dramatic thought experiment proposed by Richard Routley [1973]. 2 In the form of a second-personal question: Last Man If you were the last person on Earth, would it be wrong for you to spend your remaining days going around cutting down all the trees?

What was Galileo's thought experiment?

Galileo thought that a ball, rolling or sliding down a hill without friction, would run up to the same height on an opposite hill. Suppose that the opposite hill was horizontal. Would the ball's motion continue forever along the tangent, or forever parallel to the Earth's surface?

What are the top 10 experiments of all time?

The top 10 experiments of all time often highlight breakthroughs in physics and psychology, including Galileo's inclined planes (motion), Newton's prism (light), Young's Double Slit (wave-particle duality), Cavendish's torsion balance (gravity), Michelson-Morley (failed ether, leading to relativity), Rutherford's gold foil (nucleus), Milgram's obedience tests, Zimbardo's Stanford Prison Experiment, Asch's conformity studies, and Bandura's Bobo Doll (social learning), showcasing fundamental shifts in understanding the universe and human behavior. 

What is the forbidden baby experiment?

The orphans of Romania were participants in what is sometimes called “the forbidden experiment”: depriving human infants of intimacy, affection, and human contact is an inhuman practice. It is an experiment which no ethical researcher would set out to do.

What is the greatest failed experiment of all time?

The experiment in question, the Michelson-Morley experiment, would become one of the most famous failed experiments in history. The idea behind the Michelson-Morley experiment can be simplified to the analogy of a person swimming in a river with a current.

What was the first thought experiment?

Written evidence of thought experiments began to appear in Ancient Greece with the Pre-Socratic philosophers, who used it as a conceptual framework for solving mathematical equations. One of the earliest examples is Greek philosopher Zeno's paradox titled Achilles and the Tortoise.

What are the 7 biggest unanswered questions in physics?

The 7 biggest unanswered questions in physics often include unifying gravity with quantum mechanics (Quantum Gravity), explaining Dark Matter and Dark Energy, understanding the Matter-Antimatter Asymmetry, the nature of Time's direction (Arrow of Time), what happened before the Big Bang, the origin of particle Generations, and resolving issues like the Hierarchy Problem (why gravity is so weak) or the proton's size. These mysteries challenge our fundamental understanding of the universe's building blocks and evolution, pointing to gaps in current theories like General Relativity and the Standard Model. 

What are the famous free will thought experiments?

There are four that I would like to point out here, each has been used at different times to argue either for or against the existence of free will. These are Buridan's ass, Laplace's demon, the Libet experiment, and the Frankfurt cases.

Has the human race ever come close to extinction?

00:30 Early humans pushed to brink of extinction

Around 900,000 years ago the ancestors of modern humans were pushed to the brink of extinction, according to new research.

What does Kant say about animals?

Kant himself did not think that we had any direct ethical duties to animals. He believed that the only reason we should avoid being cruel to animals is that in doing so we might develop cruel habits that we would inflict on other people.

What is the black hole thought experiment?

In quantum information, the Hayden–Preskill thought experiment (also known as the Hayden–Preskill protocol) is a thought experiment that investigates the black hole information paradox by hypothesizing on how long it takes to decode information thrown in a black hole from its Hawking radiation.

What was Albert Einstein's happiest thought?

Einstein's happiest thought was his leap from the observation that a falling person feels no gravity to the realization that gravity might be equivalent to acceleration.

Has the EPR paradox been solved?

Indeed, if questioned about its solution, many physicists will still affirm today that the paradox has been solved by the Bell-test experimental results, which have shown that entangled states are real.

What does the Bible say about quantum entanglement?

While the Bible doesn't explicitly mention "quantum entanglement," many Christian spiritual writers draw parallels between quantum physics concepts and biblical themes, seeing echoes of entanglement in the mystical interconnectedness between God and believers, Christ's indwelling, the instantaneous power of prayer, and the spiritual unity of believers, suggesting a non-local, unified reality transcending physical separation. These connections often use passages like John 15:4-5 (abiding in Christ) or Paul's writings about believers being "in Christ" to illustrate this spiritual unity, akin to entangled particles. 

What is the hardest question in quantum physics?

The hardest quantum physics question is unifying quantum mechanics with general relativity into a single Theory of Quantum Gravity, which involves solving mysteries like the black hole information paradox, understanding singularities (Big Bang, black holes), and reconciling gravity (spacetime) with quantum forces. This quest explores fundamental questions about spacetime's nature and how gravity operates at quantum scales, requiring new mathematics to describe reality beyond the Standard Model. 

How can a photon know if someone is watching?

A photon or some other elementary particle does not "know" anything. It certainly doesn't know if it is being observed. An elementary particle is a unit excitation of a fundamental field.
