Daily Science Quiz
Ten questions a day on research figures: who leads a field, which side is higher, true or false, estimates, rankings, growing topics and a little geography. The same ten for everyone, new each day at midnight UTC, with a rank among the day's players.
Every question is built from the OpenAlex figures used across Science Explorer, and each answer shows the numbers and links to the pages behind them. The rank counts each finished run once: it is the place among today's players by score, and the rank over the days is the average share of players beaten, over the last thirty days played, kept on this device. The share who chose each option counts every answer given today. The streak counts consecutive days played on this device.
