The actual work at this stage was as tedious as before, but I was pretty interested. After all, it was my first opportunity to conduct quantitative measurements of lightning. Zhao Yu, that slacker, noticed this and began to slack off even more. It got to the point that when Zhang Bin was not around, Zhao Yu simply dumped his entire workload on me and went off to go fishing in a nearby stream.

As measured by the magnetic alloy recorders, the lightning current averaged around ten thousand amps and peaked at more than a hundred thousand, which meant we could calculate the voltage at one billion volts.

“What could you produce under those extreme physical conditions?” I asked Zhao Yu.

“Produce?” he said dismissively. “The power of an atomic blast or a high energy accelerator is far greater, yet it won’t produce the sort of thing you’re thinking of. Atmospheric physics is a mundane subject, yet you want to turn it mysterious. I’m the opposite: I’m used to taking sacred things and turning them ordinary.” Saying this, he gazed out into the dark green of the tropical rain forest that surrounded the weather station. “Hey, you go chasing after your mysterious fireball. I’m going to enjoy an ordinary life.”

His career as a master’s student was reaching an end, and he had no desire to continue on to a PhD.

Back at school, classes continued, and I took part in a few more of Zhang Bin’s projects outside of class and during the holidays. His methodical fastidiousness sometimes annoyed me, but apart from that he was easygoing enough, and I gained an immense amount of practical experience from him. But more importantly, his specialty was in line with my own quest.

For that reason, when it came time to graduate, I chose to test into the master’s program under him.

As I had anticipated, he firmly opposed my choice of ball lightning as a master’s thesis topic. In all other matters he was accommodating, including tolerating a lazy student like Zhao Yu, but in this there could be no accommodation.

“Young people should not get wrapped up in imaginary things,” he said.

“The existence of ball lightning is recognized by the scientific community. You think it’s imaginary?”

“Fine, I’ll repeat myself. What point is there to something that is not included in international standards or national regulations? When you were an undergraduate, you could study your own specialty using basic scientific techniques, but now that you are a graduate student, that’s no longer acceptable.”

“But Professor Zhang, atmospheric physics is pretty much a basic discipline now. It’s not just a tool for engineering; it has a duty to help us understand the world.”

“But in this country, the priority is to serve the cause of economic development.”

“Even so, if the anti-lightning measures at the Huangdao Oil Port had taken ball lightning into account, the 1989 catastrophe might have been avoided.”

“The source of the fire in Huangdao is just conjecture. Research on ball lightning itself is full of more conjecture. From now on, you’re going to avoid such harmful elements in your studies.”

There would be no further discussion of the subject. I was prepared to devote my entire life to that quest, so it was unimportant what I studied for the three years I was in graduate school. So I submitted to Zhang Bin’s suggestion and did a project on lightning defense computer systems.

Three years later, my graduate studies reached a smooth and uneventful conclusion.

To be fair, I learned quite a bit from Zhang Bin during those three years, and I benefited substantially from his technical rigor, proficient experimental skill set, and rich engineering experience. But, as I knew three years before, the core of what I required I was unable to find with him.

I also learned a fair amount about his personal life: his wife had died long ago, he had no children, he had lived alone for many years, and he had few social interactions. His humdrum existence echoed my own, but, to my mind, that lifestyle required the presence of an overpowering quest—a “fascination with something,” in my dad’s words, or what the pretty girl in the library six years ago had called “a sense of purpose.” Zhang Bin, with no goals and no fascination with anything, mechanically carried out his boring applied research, treating it as a job rather than a pleasure. His attitude toward fame and fortune displayed a similar rigidity. If that really were how he felt, then life must be a kind of torment for him, and hence I felt a little sympathy.

However, I did not think I was ready to explore the mystery quite yet. No, everything I had studied over the course of six years only made me feel my impotence all the more strongly. My first efforts were primarily in physics, but I eventually discovered that physics itself was a huge mystery, at the far end of which the very existence of the world was called into question. And assuming that ball lightning was not a supernatural phenomenon, only relatively low-level physics would be necessary to understand it: Maxwell’s Equations and the Navier-Stokes Equations in fluid mechanics would be sufficient (how superficial and naïve were my initial ideas). But compared to ball lightning, all known structures in electromagnetism and fluid mechanics were simple. If ball lightning was indeed a complicated structure in stable equilibrium constrained by the basic laws of electromagnetism and fluid mechanics, its mathematical expression would have to be incredibly complex, just like simple rules for black and white pieces can describe the intricate positions of Go, the world’s most complicated game.

This, then, was what I felt I needed now: first, mathematics; second, mathematics; and third, more mathematics. Complex mathematical tools were absolutely necessary for cracking the secret of ball lightning, tools as unruly as an unbridled mustang. Although Zhang Bin felt that my math skills far exceeded the standard requirements of atmospheric physics, I knew that I was still far from the level required for ball lightning research. As soon as complicated electromagnetic and fluid structures got involved, mathematical descriptions turned savage, involving weird partial differential equations that tangled up like twine, and dense matrices that held blade-filled traps.

With so much to learn before my explorations could truly begin, I knew I could not leave the campus environment immediately, so I decided to study for a PhD.

My doctoral advisor, a man named Gao Bo, had a formidable reputation and had gotten his PhD at MIT. He was the polar opposite of Zhang Bin. What first attracted me to him was his nickname, “Fireball,” which I later learned had nothing at all to do with ball lightning. Perhaps it had more to do with his nimble mind and vigorous personality. When I suggested ball lightning as the topic of my dissertation, he acquiesced immediately, at which point I began to have second thoughts: the project would require a large-scale lightning simulator, but there was only one in the country and I would never have a chance to use it.

But Gao Bo disagreed. “Listen, all you need is a pencil and a piece of paper. What you’re constructing is a mathematical model for ball lightning. It needs to be internally consistent, innovative, mathematically flawless, and executable on a computer. Treat it as a piece of theoretical art.”

Still, I had worries: “Will they accept something that forgoes experimentation entirely?”

He waved his hand. “Are black holes accepted? To date there is no direct evidence of their existence, yet look how far astrophysics has developed the theory, and how many people make a living off it. At the very least, ball lightning exists! Don’t worry. If your dissertation meets the requirements I gave you but still doesn’t pass, I’ll resign and we’ll get the hell away from this college!”

Gao Bo was a little too far toward the opposite extreme from Zhang Bin, I thought—I wasn’t on a quest for a piece of theoretical art. Still, I was pleased to be his student.
