These temperature variations change the thickness of the text's "font," producing optical variations (light, medium, bold, and extra bold) in the typographic weight of the white lines.

In the ensuing years this architect could generally be counted on for big, bold forms; a fetishistic obsession with technology; and a magician's bag of optical tricks.
However, less is known about BOLD spatiotemporal dynamics in the subcortex, which is beyond the reach of conventional optical imaging techniques in rats.
The optical transitions observed in the PV spectra are indicated by vertical arrows; bold arrows show drift directions of the optically excited charge carriers under the internal field (PV creation); E F is Fermi energy.
Bold formatting should only be used for run-in headings and small capitals for indicating optical activity (D- and L-dopa).
Looking very much like its predecessor the Bold 9900, the Classic is a dense phone edged in metal and featuring a four-row keyboard, optical track pad, and touchscreen.
Here Christus borrows an optical device from the work of his predecessors Jan van Eyck and Rogier van der Weyden, but is bolder and more accomplished with his use of light, which art professor Lola Gellman describes as having "no counterpoint in previous art".
