But, over nearly three centuries, the classification system used to organize much of our biological knowledge has remained remarkably arbitrary and ancient: The socalled binomial system of genus and species that Linse and thousands of other biologists use today was first proposed by a Swedish biologist born 300 years ago Wednesday, Carolus Linnaeus.

There is in fact a probability distribution, known as the binomial distribution, of how many times the number 1 shows up.

He also developed a way to name plants called binomial nomenclature (bi NOH mee ul · NOH mun klay chur).

The controversial "binomial" electoral system that guarantees congressional seats for the political right remains in place.

According to this "binomial" nomenclature each plant or animal received a generic and a specific name, as, for instance,

· Fixed gamma () and derivative functions such as binomial () returning wrong results at integer inputs being divisible by a large power of 2.

The presentation then went through the "binomial" break apart strategy that's supposed to be teaching kids "algebraic principles in 4th grade", the "change it and make it easier problem" using 98 x 15 as an example (ok change it to 100×15  2×15 = 1500  30 = 1470).

While structures such as binomial heaps and redblack trees are presented, it is assumed that the reader already knows and understands them.

Before Linnaeus '"binomial" scheme, the names of particular species were often strings of descriptive Latin terms that grew to such lengths as this: Convolvulus foliis palmatis cordatis sericeis: lobis repandis, pedunculis bifloris.
