When you play the game, a series of pop-ups with educational content describing each new unlocked technology will appear. This gives you an understanding of the different technologies and the dependencies between them.
To begin with, you read about why rubidium is an important atom in ultra-cold quantum experiments and proceed with unlocking the different technologies in the game.
Example of a pop-up in the game with educational content:
You will encounter 34 different technologies during the game (if you make it all the way through and win the game). The different technologies along with their short descriptions and the learning goals are outlined in a table. You can find the table of technologies in the link.
