- de broglie equation — the postulate of wave mechanics that a particle of mass m moving at a velocity v will have the properties of a wave of wavelength h / mv (de Broglie wavelength) where h is Planck's constant.

- diamond ring effect — a phenomenon, sometimes observed immediately before and after a total eclipse of the sun, in which one of Baily's beads is much brighter than the others, resembling a diamond ring around the moon.
- dig one's own grave — If you say that someone is digging their own grave, you are warning them that they are doing something foolish or dangerous that will cause their own failure.
- digital electronics — (electronics) The implementation of two-valued logic using electronic logic gates such as and gates, or gates and flip-flops. In such circuits the logical values true and false are represented by two different voltages, e.g. 0V for false and +5V for true. Similarly, numbers are normally represented in binary using two different voltages to represented zero and one. Digital electronics contrasts with analogue electronics which represents continuously varying quantities like sound pressure using continuously varying voltages. Digital electronics is the foundation of modern computers and digital communications. Massively complex digital logic circuits with millions of gates can now be built onto a single integrated circuit such as a microprocessor and these circuits can perform millions of operations per second.
