How the Result of a Coin Toss Can be 100 heads

Caption

This image shows how the result of a coin toss can be 100 heads. First, you preselect on heads. Then, a friend performs a weak measurement and occasionally flips the coin. When the coin comes back tails, then you calculate (using the mathematical steps in Ferrie and Combes' paper) what your friend measured. The calculation says they measured 100 heads, not just heads!
