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.
A nanometre is very, very small â there are a million of them in a millimetre. âNanoâ means âa billionthâ (a billion is a thousand million), so: 1  a nanometre is a billionth of a metre. 2  a nanosecond is a billionth of a second. nanometre is a measurement â it is clearly defined as a billionth of a metre. On the other hand, although nanoscale is a scientific term, it means different things to different people. Many nanoparticles are ball-shaped, so all dimensions are small.
