If you've done any sort of study of the history of major scientific breakthrough of the past few centuries, you'll know that most of them have come from serendipity, pure luck, accident, etc. Mark and his insane project-to-save-the-company has hit a snag at the last step, the zero hour. It's the sort of setback that, given a couple of weeks, wouldn't be too big a deal. But they've got less than two days to figure out what the snag is, how to work around it, and how to optimize the step. And if they can't get things working in this very limited timeframe, then the big push will have failed after three weeks of very hard, remarkable work.
Please think happy thoughts. Please pray. Please concentrate on getting the universe to do its trippy science serendipity thing to make things work.
