1,407,487 | Normalization process theory is regarded as a middle range theory that is located within the 'turn to materiality' in STS. It therefore fits well with the case-study oriented approach to empirical investigation used in STS. It also appears to be a straightforward alternative to actor–network theory in that it does not ... | https://en.wikipedia.org/wiki?curid=15450044 | 1,406,697 |

488,441 | Weismann started out believing, like many other 19th century scientists, among them Charles Darwin, that the observed variability of individuals of one species is due to the inheritance of "sports" (Darwin's term).

157,508 | The phylum was originally called "Polyzoa", but this name was eventually replaced by Ehrenberg's term "Bryozoa". The name "Bryozoa" was originally applied only to the animals also known as Ectoprocta (), in which the anus lies outside the "crown" of tentacles.

1,224,012 | The built-up gun was of an all-steel construction, using a radial expansion design; this was an advance on earlier British heavy guns, which employed a wire-wound technology.
