Cracking the Scratch Lottery
A very smart statistician has realized that it is possible to sort, with upwards of 90 percent accuracy, the winning scratch tickets from the losing ones before anything is scratched off.
As a trained statistician with degrees from M.I.T. and Stanford University, Srivastava was intrigued by the technical problem posed by the lottery ticket: "The tickets are clearly mass-produced, which means there must be some computer program that lays down the numbers. Of course, it would be really nice if the computer could just spit out random digits. But that’s not possible, since the lottery corporation needs to control the number of winning tickets. The game can’t be truly random. Instead, it has to generate the illusion of randomness while actually being carefully determined."

- When the Berlin Wall fell in 1989, many Americans jumped for joy. At the time, some believed there weren't going to be any more political disagreements anywhere in the world. They thought American democracy had won the "war of ideas."
- American exceptionalism has sought to create a world order that's really a mirror image of ourselves — a liberal world order founded on the DNA of American thinking. To many abroad this looks like ethnic chauvinism.
- We need to move on from this way of thinking, and consider that sometimes "problem-solving," in global affairs, means the world makes us look like how it wants to be.
Scientists make an important discovery for the future of computing.
- Researchers find a new state of matter called "topological superconductivity".
- The state can lead to important advancements in quantum computing.
- Utilizing special particles that emerge during this state can lead to error-free data storage and blazing calculation speed.
