Method x journal

The Shettles Method is a child conception idea that is reputed to help determine a baby's sex.
It was developed by Landrum B.
Shettles in the 1960s and was publicized in the book How to Choose the Sex of Your Baby, coauthored by Shettles and David Rorvik.
The book was first published in 1971 and has been in print in various editions ever since.
By following the various methods outlined in the book, it is proposed that a couple can affect the probability of having a boy or a girl.

X-ray crystallography is the experimental science determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract into many specific directions.
By measuring the angles and intensities of these diffracted beams, a crystallographer can produce a three-dimensional picture of the density of electrons within the crystal.
From this electron density, the mean positions of the atoms in the crystal can be determined, as well as their chemical bonds, their crystallographic disorder, and various other information.
