Discussion Systematics comprises a large field of endeavor that attempts to reconstruct the relationship of living organisms - the phylogeny (evolutionary history) of different species. In addition ... the ultimate evidence of evolutionary relationships. Base sequencing is now being used to confirm or revise older taxonomic categorizations.

By definition, a black hole is a region where matter collapses to infinite density, and where, as a result, the curvature of space-time is extreme ... the original source increases. Although many physicists doubted the existence of gravitational waves, physical evidence was presented when American researchers observed a binary pulsar system that was thought to consist of two neutron stars orbiting each other closely and rapidly. Radio pulses from one of the stars s...

Part 1: Analogue to digital converters The first step in digitalising an analogue waveform is to change an occurrence that ... digital signal into an analogue signal, the opposite effect of a sample and hold circuit must take place first. The circuit is fed a string of binary which is then converted into voltages, resulting in a signal that looks like the output of the quantisation circuit. (See figur...

Leibniz made a machine that could also multiply and worked on a system of dials and gears. The centrepiece of Leibniz's machine was its stepped-drum gear. It wasn't until 1820 when a Frenchman, Charles Xavier Thomas de Colmar invented a mechanical calculator (the arithometer ... electronic computer that applied Boolean Algebra to computer circuitry.
