ou can't put a ‘1’ ina memory location and be sure when you come to read it you will get a ‘1’ back. You have to factor in the possibility of error. Quantum effects can be annoying - requiring us to devise all manner of error checking hardware — but they can also be helpful. Richard Feynman proposed using

piece of trivia links Hofstadter with Penrose: Roger Penrose and his father invented the Penrose Steps, inspiring the never- ending staircase in the Escher prints featured in Hofstadter’s book. For movie buffs, the Penrose steps appear in the film Inception, starring Leonardo DiCaprio. The fact we get pl

finger, y and your thumb, z. At any moment you can move your hand to point in any direction and take a measurement. We will have to round up or down. Quantum mechanics is named ‘quantum because ail the readings must be whole numbers. You will never see 10% spin in x, 90% in y and 85% in z; just ones, and z

ile, we realize there might be no solution. And indeed there is not. This is the Kochen- Specker Paradox. The odd shaped cubes on the building in the Escher print are an example of one of these impossible figures. An analogy to this problem is trying to solve a_ broken Rubik’s Cube. There is a really mis

of the philosophical argument. I also avoid a strongly historical narrative, but if you enjoy the history of science I recommend, The Missing 4%, and Quantum for a really clear exposé of the issues HOUSE_OVERSIGHT_016087 398 Are the Androids Dreaming Yet? around quantum mechanics, relativity and cosmolo
