  • Interesting fact: Blue and fin whales can create the loudest sound by animals ever recorded; sounds that have more energy than jet plane noise.
    • n fin An extension from the body of an aquatic animal, which serves for propelling, steering, or balancing in the water, and is developed from various parts of the body, generally as an alate or wing-like organ; a pinna. In fishes there are unpaired or vertical and paired or horizontal fins. The former are dorsal, anal, or caudal. The paired fins are pectoral and ventral, the former homologous with the anterior member or manus (hand) of terrestrial vertebrates, the latter homologous with the posterior member or pes (foot). The relations of the spinous and soft portions of the dorsal and anal fins, and the position and structure of the ventral fins, as well as various other modifications of all the fins, have been much utilized for the classification and discrimination of groups in ichthyology. The names of the fins are commonly abbreviated A., C., D., P., V., as in the accompanying figure. In the lower fishes the fins are sustained in an erect position by numerous filamentary or slender rods (actinotrichia), but in the typical fishes there is a growing together of the actinotrichia into special rays or spines. In various forms (Nematognathi, Salmonidæ, etc.) there is likewise a pocket-like sac or ridge on the hinder part of the back, generally consisting of adipose matter and called an adipose fin.

In science:

It is proved that there exists an (ω1 , ω1 ) Souslin gap in the Boolean algebra (L0 (ν ) /Fin, ⊆∗ ae ) for every nonseparable measure ν .
Random gaps
For example, if (A, B ) is an (ω1 , ω1 ) gap in P (N) / Fin and Q is a poset which collapses ℵ1 , then by Hadamard’s theorem, which generalizes to any limit ordinal of countable cofinality, forcing with Q must introduce an element of P (N) / Fin which interpolates (A, B ) and thus renders it a non-gap.
Random gaps
The statement “all (ω1 , ω1 ) gaps in P (N) / Fin are indestructible” is in fact a Ramsey theoretic statement which is closely analogous to Souslin’s Hypothesis.
Random gaps
When working with pregaps in P (N) / Fin one often works with representatives (i.e. subsets of N) of the equivalence classes.
Random gaps
Souslin’s Hypothesis is consistent with the existence of a Souslin (ω1 , ω1 ) gap in P (N) / Fin.
