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…)
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.
