To 'have a chip on your shoulder' means to have an irrational resentment directed at other people (especially those who are not a member of a group or community which you identify with) because of a sense of inferiority (or an erroneous impression that others see you as inferior).
Part of the Nanotechnology glossary: A nanometer is a unit of spatial measurement that is 10-9 meter, or one billionth of a meter. It is commonly used in nanotechnology, the building of extremely small machines. This was last updated in September 2005. Contributor(s): Ian Pulham.
There are 1.0E-6 meter in a micrometer. 1 Micrometer is equal to 1.0E-6 Meter. 1 um = 1.0E-6 m. A micrometer, or micron, is a unit of length sometimes used in SI as a 1Ã10â6 of a meter. This is a quite specific measurement unit used in science (i.e. for measuring various types of wavelength, etc.) or in industrial technology.
