Claims

Was that real physics?The swipe deck: scenes, myths, viral claims Did they do what they said?Every tracked claim, scored on its deadline How good are my predictions?Your proofs and predictions, scored honestly

The race

Who is actually ahead?The scoreboard, and the desk's own forecasts Did the advantage last?Every claim, and the classical answer that followed What is the number that matters?The threshold, live What just happened?Desk notes: dated, written by hand What is still open?Questions nobody has answered, and ones that only look open

Our own record

Where were we wrong?Every mistake, logged and dated How do you check a number?What catches errors, and what it misses
