Whitney does not turn around. “I have time.” The room cracks open with a small involuntary laugh. Not at her, with her. It’s the laugh of 180 people watching a bully get answered in three words. Ashford’s neck flushes red. He glances at the back wall. The live stream comment counter is climbing in real time. He can see it. 12,400. 14,000. 17,200. The count is doubling every 30 seconds. His face is on every one of those screens. Henrik Sandberg, his own grad student, has set his notebook down and is openly watching with both hands at his temples. The stopwatch reads 0:42. Whitney rewrites the next line. Three faculty members in the front row stand up again. Eleanor Vance has not blinked in 2 minutes. Ashford tries one more time. He pulls out a different weapon. Sarcasm. Ladies and gentlemen, I want to remind everyone that correctness is not the same as rigor. This is a performance. A very entertaining performance. But when this is over, I’d ask all of you Professor Ashford.
Whitney’s voice cuts him off. She still has not turned around. You’re using my time. The room is now openly tense. Phones up everywhere. A young undergrad in the back has started crying. Not from sadness, from something she doesn’t have words for yet. Audrey Whitfield is still recording. Her free hand is gripping the edge of her seat. The stopwatch reads 0:32. Whitney spots the symmetry. The symmetry. The one Ashford never saw in 9 years. She draws a small triangle in the corner of the board to flag it. Three more people stand up. Henrik Sandberg writes one line in his notebook in his shakiest handwriting. The line reads, “I’m watching a paper get written in real time.” In the audience, an elderly mathematician in the third row, emeritus, retired 10 years ago, came to the colloquium today only because his wife dragged him out, has taken off his hearing aid. He is not turning it off. He is taking it out so he can hold his head in both hands and not be distracted by anything but what is on the board. A young woman two rows behind him has pulled out a small notebook and is copying Whitney’s work down line by line. She will keep this notebook for the rest of her life.
In 9 years, she will publish a paper that builds on this proof. And in the acknowledgements, she will write, “To the woman who taught me what mathematics looks like when nobody has permission to silence it. The live stream comment counter clicks past 25,000. The Harvard math department’s YouTube channel has, in the last 6 minutes, gained more new subscribers than it has gained in the previous 6 years. The stopwatch reads 0:20. In Brookline, Teddy is on the floor of his dorm room. He has called their grandmother in Atlanta. He’s holding the phone up to his laptop screen so she can hear and see. Their grandmother is whispering over and over. Lord. Lord. Lord.
