Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
The material effect produced by the refraction of different wavelengths of electromagnetic radiation through slightly different angles, resulting in a failure to focus. It causes colored fringes in the images produced by uncorrected lenses.
- ‘For instance, a white-light profilometer system uses chromatic aberration or an interferometry and phase shift technique to measure surface roughness to 1 nm.’
- ‘The chromatic aberration, the secondary spectrum, and the spherical aberration could be corrected, and although the spherochromaticity was large, it was tolerable.’
- ‘The effects of spherical and chromatic aberration increase as the pupil expands.’
- ‘Typical aberrations that can impact imaging performance include astigmatism, chromatic aberration, and spherical aberration.’
- ‘Newton was led by this reasoning to the erroneous conclusion that telescopes using refracting lenses would always suffer chromatic aberration.’
We take a look at several popular, though confusing, punctuation marks.
