The detection of the cloud is described using physics equations, all of which are included in the book.

The gravitational constant, called G in physics equations, is an empirical physical constant.

"It's like a physics equation," he said, writing off competitors who use smelters in the United States that have already closed because of high energy costs.

Once safe, they find the package contains an extremely complex physics equation that Walter cannot immediately understand.

Even the physics equation on the book's back cover has outsized verve.

Mathematically, classical physics equations are ones in which Planck's constant does not appear.

He invoked the physics equation that describes the amount of kinetic energy in a moving object, saying, "That's when it came home to me what 1/2mv2 means."

In the end, I think the work on subjective time will force a change in how we think about time in the physics equations.

On the other hand, physics equations describe our reality in three dimensions and usually do not work when extended to four and higher dimensions.

That is because physics equations describe physical reality and our reality is three dimensional.
