Coelacanth is a rare order of fish. The two extant species include the West Indian Ocean Coelacanth (Latimeria chalumnae) and the Indonesian Coelacanth (Latimeria menadoensis). They follow the oldest known living lineage of Sarcopterygii (lobe-finned fish and tetrapods); this classification means they are more closely related to lungfish, reptiles and mammals than to the common ray-finned fishes. The species are the most endangered order of animals in the world. Both species are threatened with the The West Indian Ocean Coelacanth classified as a critically endangered species. Coelacanths have been found along the coastlines of the Indian Ocean, Indonesia, and Tanzania. (more…)
In this blog I demonstrate how you can implement and take advantage of caching in your Python scripts/applications.
Caching allows you to complete tasks more rapidly by storing and reusing results for repeated operations using the same criteria. For example, consider a function that takes several arguments and performs a complex calculation. What if you passed the same arguments to this function ten times; well, without caching, the same operation and complex calculation will be performed ten times. (more…)
University of California, Berkeley Astronomers have discovered the largest black holes known to date. The black holes are estimated to be have masses equivalent to about 10 billion suns each (one black hole being slightly bigger than the other). The two black holes are in clusters of elliptical galaxies greater than 300 million light years away (1 light year is approximately 5.8 trillion miles). (more…)
In the past, organic compounds were restricted to those that could be produced only from living entities. These compounds were thought to contain a “vital force” based on their natural origin. This “vital force” concept was disproved in 1828 by a Geman chemist, Friedrick Wohler. Wohler synthesized a molecular compound found in human urine called urea. To accomplish this task he used the molecular compounds ammonia and cyanic acid. Urea became the first organic molecule synthesized by a chemist.
