21.   In his plan, big particle accelerators would, by a kind of nuclear alchemy, transmute radioactive wastes and plutonium into more benign elements before they were buried.

22.   It depended on a technique powered by X-rays from the particle accelerator at the Brookhaven National Laboratory on Long Island.

23.   Many physicists believe the dark matter will turn out to be swarms of particles predicted by their theories but not yet detected directly in particle accelerators here on Earth.

24.   More drinks arrived, and the restaurant revolved like a particle accelerator.

25.   Nor could they foresee that refined versions of the cathode-ray tube would one day be used as huge particle accelerators and as television picture tubes.

26.   One includes a virtual particle accelerator, where they can see how electrical resistance works.

27.   One way is with the help of huge particle accelerators.

28.   Only a few years later, such spinless particles appeared in the high-energy collisions at particle accelerators.

29.   One by one, the quarks have revealed themselves through the telltale streaks they leave across the electronic detectors inside particle accelerators.

30.   Particle accelerators are still not powerful enough to mimic the cosmos earlier on, when it was even hotter and denser.
