I have a new request. Once I get to the unlocking 4 digit code, there's almost nothing to help me decide how to crack it. The clue you give needs some sort of cypher, which doesn't appear to be anywhere. I've tried math, patterns, so far nothing works, and I'm not willing to brute force it.
Look at the picture of the scientists, without the magnifying glass but with the hand. The clue is written on the nameplate. It’s not difficult.
