I would invent:
Lemba bread for traveling.
Technology I love:
Well, I used to have this computer named Lola... as computers go, she was *very* personal. She had this tattoo on her underside -- "110/220 V AC" -- I'll never forget it.
How do you use math in your daily life?:
It's the language of science. Or, rather, it's the universal language scientists use to describe nature. Then the trick is to use our human-interface language to explain what the math is saying.
What technology do you use every day?:
Fire. Sticks. Wheel, sometimes.
