Discs that drink the steam, a channel with no moving part that refuses to flow backward, the Hotel New Yorker years, and the last page of the notebook.
Tesla's disc turbine and valve worked by hand, tested against 2021 measurements, and the end of his story: 1943, John G. Trump and Belgrade.

Morgan's money, Stanford White's laboratory, a tower crowned with a sphere sixty-eight feet across, and the arithmetic of how much charge it could hold.
Tesla's Wardenclyffe tower: why the terminal was huge and smooth (E = V/r, C = 4πε₀r), Marconi in 1901, and an honest verdict on wireless power.

A storm walks east across the plains, my relay counts its nodes, and I spend five years deciding what was holding the waves still.
Tesla's night of 3 July 1899: the receding storm, his stationary waves, the 6 Hz of patent 787,412, and why Schumann's 7.83 Hz is a near-miss.

A barn on a plateau, a coil fifteen metres across, a free coil standing on a driven one, and the long work of finding its pitch.
Tesla's 1899 Colorado Springs notebook: the extra coil as a quarter wave, why a ball on top lowers its pitch, and three ways he measured capacity.

A boat steered by impulses through the air: the grains that listen, the circuit tuned to one note, and four states of a clockwork that make a machine obey.
Tesla's notebook of 1897 and 1898: how a coherer, a tuned circuit and a four-quarter commutator steered a boat, and why he thought it would end war.

The egg that stands at Chicago, a laboratory lost to fire, shadows through forty feet, and the wheel at Niagara sending its power twenty-six miles to Buffalo.
Tesla's notebook, 1893 to 1896: why Niagara ran at 25 periods, why 11,000 volts saved the copper, and what a fire takes from an inventor and what it leaves.

London and Paris, 1892: a lamp lit through one wire and a hanging plate, Faraday's chair, Rayleigh's praise, a mother's death, and a sorrowful visit to Hertz.

A tube lit in empty air between two hanging sheets, and the arithmetic that says why frequency makes the impossible lamp easy.
Tesla's 1891 Columbia lecture: how an alternating electric field lights an exhausted tube, why only the field along it counts, and why frequency matters.

Why the induction coil fails at high frequency, and how a condenser, a spark and two tuned circuits without iron became the Tesla coil of patent 454,622.
Tesla tunes two coils without iron, derives their two frequencies and the voltage gain √(L₂/L₁), and files patent 454,622 for the coil.

Tesla builds a dynamo with 384 poles to reach ten thousand alternations a second, silences the arc lamp, and finds the current hiding in the skin of the copper.
Tesla works out how many poles make 10,000 alternations a second, why the iron must be wire, and why copper carries current only in its skin.

From the Paris Exposition of 1889 to a laboratory in Bonn in 1892: Tesla works through Maxwell's wave equation, measures waves on a wire, and argues with Hertz.
Tesla derives the speed of Maxwell's waves from the ratio of the units, estimates Hertz's wavelength, and takes his objections to Bonn.

A jar of glass and a loop of copper swing a million times a second of their own accord. I derive why, count the swings in a turning mirror, and weigh the thief in the spark.
Tesla derives f = 1/(2π√(LC)) and the damping of a Leyden-jar discharge, counts the swings in a turning mirror, and finds the spark's loss.

A sine is the shadow of a turning radius. With that one picture I could see every alternating circuit whole before a turn was wound.
RMS by integration, impedance, phase lag, power factor and series resonance, derived step by step from Tesla's geometric method of turning radii (proto-phasors).

Westinghouse's alternators gave 133 periods a second and my motor wanted far fewer. I spent a year between two numbers.
Why 60 Hz? Tesla's Pittsburgh year worked out: motor speed n = 120f/p, split-phase motors, lamp flicker and filament heat, and transformer iron versus frequency.

Five years after the sand in Budapest, the field turned in iron at 89 Liberty Street, and I had to say exactly what I had seen.

A converter has no moving part and turns a thousand volts into fifty as quietly as a sum is carried in the head. I wanted to know exactly why.
Why a transformer needs alternating current: the ratio of turns, V = 4.44 f N Φ, magnetising current, eddy losses and laminations, worked in Tesla's voice.
