Pythagorean expectation in sports analytics predicts a team's success using points scored and allowed to estimate what?
The Pythagorean expectation formula estimates a team's winning percentage as (runs scored)^2 / [(runs scored)^2 + (runs allowed)^2], revealing discrepancies between actual and expected wins.
The Player Efficiency Rating or PER summarizes a player's overall productivity in which sport?
PER, developed by John Hollinger in 2002, measures NBA players' per-minute productivity while adjusting for pace, defense, and team factors to gauge overall efficiency.
Sabermetrics applies statistical analysis to player performance and strategy in which sport?
Sabermetrics, derived from SABR (Society for American Baseball Research), revolutionized baseball by emphasizing advanced metrics like on-base percentage over traditional stats such as batting average.

Named after its creators Rivest, Shamir, and Adleman, which algorithm secures much of the internet through public-key encryption?
RSA, invented in 1977, secures internet communications by using a public key for encryption and a private key for decryption, relying on the difficulty of factoring large semiprime numbers.
Which Nazi German cipher device, cracked by Allied codebreakers including Alan Turing, used rotating wheels to encrypt messages?
The Enigma machine featured three or four rotating rotors that altered the electrical path for each letter, producing over 150 million possible daily settings to challenge codebreakers.
Julius Caesar used which simple encryption method that shifts each letter in the alphabet by a set number of places?
The Caesar cipher, a substitution method, shifts each letter by a fixed number—typically three positions—so "A" becomes "D" and "Z" becomes "C".
Which encryption technique offers perfect secrecy when using a truly random key as long as the message, used only once?
The one-time pad, invented by Gilbert Vernam in 1917, achieves perfect secrecy because the truly random key masks the plaintext such that every possible message is equally likely given the ciphertext.
