3. INANIMATE PRODUCTION LIKE ANIMATE REPRODUCTION<br />

the early 1950s was no lesser a feat than the ring of LEP in the late<br />

1980s. Particle physicists gave the best of themselves and were rewarded<br />

comparably in each case. T. W. L. Sanford studied the<br />

succession between accelerators and found that as soon as a new, more<br />

powerful accelerator came into existence, physicists, experiments, and<br />

publications shifted from the old to the new. This changeover was not<br />

abrupt, however, but along smooth S-curves. 5<br />

The reason the size of accelerators has grown to practically absurd<br />

dimensions is that we have progressively exhausted the utility of the<br />

fundamental principle of electron accelerators: the radio-frequency electromagnetic<br />

cavity used for acceleration. Every new horizon of particle<br />

physics research requires higher particle energies, more acceleration, and<br />

more radio-frequency cavities. In the end, it is purely the size, with the<br />

associated expenses, which renders the process obsolete.<br />

The theoretical growth curve fitted to the data points allows the possibility<br />

that one or two more accelerators may still be built worldwide.<br />

But it is more likely that existing accelerators become upgraded in performance,<br />

for example the LHC (Large Hadron Collider) designed to<br />

replace LEP inside the same tunnel. By and large the era of high-energy<br />

physics particle research as we have known is coming to a close. It is<br />

also of interest to note that the nominal beginning of the curve (the 1<br />

percent of maximum level) does not point at Rutherford’s famous experiment<br />

in 1919 when he first used particles to explore the structure of<br />

the atom. The beginning of the accelerator era is pinpointed at the outbreak<br />

of World War II, but “technicalities” during the war years delayed<br />

the actual construction of laboratory sites for about ten years. The data<br />

do in fact show an early catching-up effect. Seen in retrospect, Rutherford’s<br />

seed was given a chance to sprout thanks to the intense activity on<br />

nuclear research during the war years. One may even want to see the<br />

subsequent demonstration of overwhelming power in nuclear energy as<br />

the potent fertilizer that made accelerators grow to gigantic dimensions.<br />

In all three examples—the construction of supertankers, cathedrals,<br />

and particle accelerators—competitive growth was the law in effect. All<br />

three were relatively short-lived endeavors. Extinction was probably<br />

precipitated by competition-related hardships attributed to their exorbitant<br />

size. Size, however, is not necessarily a reason for early extinction.<br />

The real dinosaurs lived longer than most species on earth, and they did<br />

not become extinct by slowly phasing out due to their size. The most<br />
