If you've ever experienced the exceptionally powerful and reverberating sounds of a jet during takeoff, you likely won't be surprised that the noise produced by jet engines is ranked among the loudest of human-generated noises.

The life of a subatomic particle can be hectic. The charged nuclei and electrons that zip around the vacuum vessels of doughnut-shaped fusion machines known as tokamaks are always in motion. But while that motion helps produce ...

Fluid flows can take one of two forms: well-ordered "laminar" or highly disordered "turbulent" motion. Although everyday experience shows that laminar motion in simple shear flows as in pipes or channels gives way to turbulence ...

One of the biggest obstacles to making fusion power practical—and realizing its promise of virtually limitless and relatively clean energy—has been that computer models have been unable to predict how the hot, electrically ...

For fusion reactions to take place efficiently, the atomic nuclei that fuse together in plasma must be kept sufficiently hot. But turbulence in the plasma that flows in facilities called tokamaks can cause heat to leak from ...
