Town of Princeton

Lu Zhou didn't end up writing the third line for the couplet.

However, he made some unexpected progress on his research on the Navier–Stokes equation.

"The Navier-Stokes equation on the Euclidean space R3 can be expressed as ∂tμ = Δμ + B (μ, μ), where B is a bilinear operator on the vector field without divergence, and μ obeys elimination <B(μ,μ),μ >=0…"

Lu Zhou quickly wrote it down on the draft paper while muttering to himself. Suddenly, he stopped and shook his head.

"I said I wouldn't touch mathematics when I'm home, but I can't control myself…"

Lu Zhou stopped writing. He shoved the draft paper into his suitcase, and he planned to continue with the research when he was back at Princeton.

He had an entire year to do all the research he wanted.

But he could only be with his family right now…

…

Lu Zhou didn't do any research at all for the rest of the holiday. Instead, he focused on having a great vacation.
