When they open their respective boxes, they can measure that system. Using their knowledge of quantum theory, they can also predict the results of the coin toss. The Nature website has a good diagram of this experiment, using cat-scientists as the experimenters. After running through this thought experiment, Frauchiger and Renner found that in some cases the outside-scientists can conclude with certainty whether the coin came up heads or tails.
But sometimes their predictions contradict each other. This suggests that quantum theory also contradicts itself … at least occasionally. This experiment also raises questions of how far up into the macro-world quantum theory applies.
Much of quantum theory has been applied to the quantum world, such as entangled particles or the Heisenberg uncertainty principle. But does it also apply to larger objects, such as scientists living inside a box measuring things?
One problem with putting it into practice is that you would need to be able to measure all of the quantum properties of Alice and Bob, who are part of the systems monitored by the outside-scientists. In spite of that, physicists are heatedly debating this experiment, drawing many different conclusions about what it means for quantum theory.
Nature reports that some physicists suggest that the problem may lie in how Bob interprets the message sent by Alice — something gets lost in translation. If you were to stand outside the universe—outside both space and time—and look at your life, you would see your birth, your death and every moment in between laid out as distinct points. When we ask ourselves why we think time exists, most of us would say: because we see everything changing, always. Most of my life was spent as a materialist.follow url
Schrödinger's cat could be saved, say scientists
I regarded physical matter as the basis of reality. From matter emerged biological organisms such as humans, which developed brains, and out of the brain emerged consciousness. The existence of an ether — an all-pervading medium composed of a subtler kind of matter — has been taught by mystic philosophers throughout the ages. In our everyday life, time flows in one direction—forward. When you put a frozen pizza in the hot oven, the pizza heats up.

When you knock a coffee mug off a table The most famous case study in science, prior to Freud, was published in in the Philosophical Transactions of the Royal Society by the English surgeon William Cheselden, who attended Newton in his final illness. It is precisely science that makes the key point shine most brightly: the point that there is a fundamental respect in which ultimate intrinsic nature of the stuff of the universe is unknown to us — except insofar as it is consciousness.

How did great mathematicians like Stephen Hawking and Albert Einstein make the leap from understanding basic mathematical concepts to answering fundamental questions about the Universe? It was on the edge of Berlin on July 14, , that science and spirituality came together in one of the most intellectually stimulating conversations in history.
Is math an invention of the human brain? And in a world full of its own delights, mysteries and surprises, he searches for Schrodinger's Cat - a search for quantum reality - as he brings every reader to a clear understanding of the most important area of scientific study today - quantum physics. In Search of Schrodinger's Cat is a fascinating and delightful introduction to the strange world of the quantum - an essential element in understanding today's world. The second half is the good stuff and really simplifies the strange and magical things that go on in quantum systems.
Great read if not a little frightening to know these facts!
