Quick tips

• Start with the ones you know. Lock in the pairs you're sure of first. The last ones get easier by elimination.
• Read the field. "Chemist", "Astronomer" or "Software engineer" under each name narrows it down a lot.
• Use the icons. A star means space, an atom means physics or chemistry, a screen means computing, a house means everyday inventions.
• Learn from a miss. A wrong pair tells you the pioneer's field. Use it before you tap again.
• Read the story. Each match explains the creation in one line. Next run, you'll recognise more names.
