By the end of the summer, he【B8】the mathematical approach he had been【B9】for almost three years was flawed. And now there was a【B10】pressure. Einstein discovered to his【B11】that Hilbert had taken what he had learned from Einstein's lectures and was racing to come up【B12】the correct equations first.

It was an enormously complex task. Although Einstein was the better physicist, Hilbert was the better mathematician. So in October 1915 Einstein【B13】himself into a month-long frantic endeavor in【B14】he returned to an earlier mathematical strategy and wrestled with equations, proofs, corrections and updates that he【B15】to give as lectures to Berlin's Prussian Academy of Sciences on four【B16】Thursdays.

His first lecture was delivered on Nov. 4, 1915, and it explained his new approach,【B17】he admitted he did not yet have the precise mathematical formulation of it. Einstein also took time off from【B18】revising his equations to engage in an awkward fandango (方丹戈双人舞) with his competitor Hilbert. Worried【B19】being scooped (抢先), he sent Hilbert a copy of his Nov. 4 lecture. "I am【B20】to know whether you will take kindly to this new solution," Einstein noted with a touch of defensiveness.
