helices

I now removed the helices with their soft iron cores, and replaced them by two _flat helices_ wound upon card board, each containing forty-two feet of silked copper wire, and having no associated iron.

The structure of a protein is characterized in four ways: The primary structure is the order of the different amino acids in a protein chain, whereas the secondary structure consists of the geometry of chain segments in forms such as helices or sheets.

But how about the equation for the Schrodinger wave function or an illustration of DNA helices?

Since the space is symmetric under shifting along the axis of the helices after a suitable rotation, it's then just a matter of working out how many stitches to decrease in each row and spacing these evenly along the length.

Helicopters rear and waver all around him, gusting down the avenue, toward the fissured monuments, kicking up a blast of helices that settle like pollen in a glittering layer over everyone.

One of the cool properties of helices is that it's quite easy to calculate their lengths which is really quite rare among curves.

My plan is for these helices to form the rows, working from the outside in.
