At a parade in 1850, in which over 2, 000 female soldiers participated, one of them began a speech by saying, " As the blacksmith takes an iron bar and by fire changes its fashion, so we have changed our nature.

; High Bar: A 2. 8 cm thick steel or fiberglass bar raised 2. 5m above the landing area is all the gymnast has to hold onto as he performs giants ( revolutions around the bar ), release skills, twists, and changes of direction.

Solid helium requires a temperature of 1 – 1. 5 K ( about − 272 ° C or − 457 ° F ) and about 25 bar ( 2. 5 MPa ) of pressure.

Solid helium has a density of 0. 214 ± 0. 006 g / cm < sup > 3 </ sup > at 1. 15 K and 66 atm ; the projected density at 0 K and 25 bar ( 2. 5 MPa ) is 0. 187 ± 0. 009 g / cm < sup > 3 </ sup >.

The arithmetic mean of a set of numbers x < sub > 1 </ sub >, x < sub > 2 </ sub >, ..., x < sub > n </ sub > is typically denoted by, pronounced " x bar ".

Its antlers consisted of a 2 1 / 2 meter long horizontal bar, with no tines, ending in small palmations.

For example, IUPAC has, since 1982, defined standard reference conditions as being 0 ° C and 100 kPa ( 1 bar ), in contrast to their old standard of 0 ° C and 101. 325 kPa ( 1 atm ).< ref name =" IUPAC 2 ">
