The critical mass for 85 % highly enriched uranium is about, which at normal density would be a sphere about in diameter.

The plutonium was compressed to twice its normal density before the " Urchin " added free neutrons to initiate a chain reaction.
13.
In the Bank of England s implementation it is assumed that the forecast distribution is a two piece normal or split normal density.
14.
Where \ alpha is a constant, \ phi denotes the standard normal density function, and \ Phi is the standard normal cumulative distribution function.
15.
Instead, sharks rely on a large liver filled with oil that contains squalene, and their cartilage, which is about half the normal density of bone.
16.
Simplicity and repetition of concrete structural elements, low reinforcement and pre-stress densities as well as the use of normal density concrete lead to economical construction costs.
17.
For example, the integral of the normal density function from infinity to infinity is 1 .-- talk ) 22 : 42, 22 August 2012 ( UTC)

In one of Calhoun's experiments, a square steel box, 9 feet on each side, contained 2, 600 mice, about 16 times what would be considered normal density.
19.
In the other direction as \ gamma _ 2 \ to 0 one obtains the standard normal density as the limiting distribution, shown as the black curve.
20.
The top image shows that leptokurtic densities in this family have a higher peak than the mesokurtic normal density, although this conclusion is only valid for this select family of distributions.
