The best way to judge energy gradients was to stand on a masthead and eye the rippling shimmers of Casimir radiation that surrounded the vessel.

Or is it actually that last Pi bonding to the targeted substance, releasing it's energy gradient and then becoming free Pi?

The actual process of insertion into or extraction from the Matrix took anywhere from thirty seconds to a minute, depending on the energy gradients involved.

Then, when the particles were inside the range of the strong force, they increased the energy gradient at the particle surfaces sufficiently to initiate pair production.

Most of them clustered across the shadow line, where the steep energy gradient pumped them up to hurricane force.

Where there is an energy gradient, skillful application of science and engineering can harness that energy for productive use by humans.

"So there's something like an energy gradient these others will have to cross before they can settle the universe into another stable state."

And there are very steep temperature differences, and so there are high energy gradients - another prerequisite for life.

You're still falling, but a lot more slowly; we want to be sure we can handle the energy gradients.

You can see the energy gradients.
