Episode notes
Family Connection To Practical Bell Labs Work
- Elizabeth's father worked in Bell Labs' applied division at Holmdel doing practical engineering rather than headline inventions.
- She interviewed him to learn about the mundane but crucial work that supported Bell Labs' moonshots.
Use Employer-Funded Master's With A Deadline
- Bell Labs' one-year on-campus program paid tuition and ~60% salary to get a master's if you finished in a year.
- If considering employer-sponsored grad programs, prioritise timely completion or risk losing the position.
Rare Long Tasks Often Don't Break Queues
- Queuing theory models (Poisson arrivals, exponential service) described phone operator needs but rare long calls worried managers.
- Elizabeth's GPSS simulation showed occasional long tasks didn't meaningfully disrupt system performance.
