 Stunning photo captures single atom trapped in magnetic field

https://www.rt.com/news/418754-single-atom-trap-photo/

An incredible award-winning photo reveals what a lone atom trapped in a magnetic field would look like to the naked eye.

‘Single Atom in an Ion Trap’ was taken by David Nadlinger, from the University of Oxford through a window of a ultra-high vacuum chamber that houses the ion trap. The striking image was awarded the overall prize in a national science photography competition, organized by the Engineering and Physical Sciences Research Council (EPSRC).

The nanometre (International spelling as used by the International Bureau of Weights and Measures; SI symbol: nm) or nanometer (American spelling) is a unit of length in the metric system, equal to one billionth (short scale) of a metre (6991100000000000000♠0.000000001 m). The name combines the SI prefix nano- (from the Ancient Greek νάνος, nanos, "dwarf") with the parent unit name metre (from Greek μέτρον, metrοn, "unit of measurement"). It can be written in scientific notation as 6991100000000000000♠1×10⁻⁹ m, in engineering notation as 1 E−9 m, and is simply 1/7009100000000000000♠1000000000 metres. One nanometre equals ten ångströms. When used as a prefix for something other than a unit of measure (as in "nanoscience"), nano refers to nanotechnology, or phenomena typically occurring on a scale of nanometres (see nanoscopic scale).^[1

Look up picometre in Wiktionary, the free dictionary.

The picometre (International spelling as used by the International Bureau of Weights and Measures; SI symbol: pm) or picometer (American spelling) is a unit of length in the metric system, equal to 6988100000000000000♠1×10⁻¹² m, or one trillionth (1/7012100000000000000♠1000000000000) of a metre, which is the SI base unit of length.

The picometre is one thousandth of a nanometre, one millionth of a micrometre (also known as a micron), and used to be called micromicron, stigma, or bicron.^[2] The symbol µµ was once used for it.^[3] It is also one hundredth of an angstrom, an internationally recognised (but non-SI) unit of length.
