The DNA double helix model In 1953 James Watson and Francis Crick made a scientific breakthrough when they discovered the structure of DNA. From this structure they inferred that DNA contains information written in a genetic code‚ is passed from one generation to the next. This discovery was to be a key step in the genetics revolution DNA has four molecular building blocks called nucleotides; adenine (A)‚ thymine (T) guanine (G) and cytosine (C). Purine base always pairs (by hydrogen bonding) with

5. What is it about theories in the human sciences and natural sciences that makes them convincing? Man has always struggled to understand the world around him and‚ as a result‚ has relied heavily on the sciences. The sciences first became popular in the Greco-Roman era and from then have continued to develop and ultimately diverge into two separate subjects‚ human and natural sciences. Each of these has further diverges in which there can be up to fifty categories within each subject. However

subject‚ in 1930. Raman’s research interests were in optics and acoustics - the two fields of investigation to which he dedicated his entire career. The main investigations carried out by Raman were: his experimental and theoretical studies on the diffraction of light by acoustic waves of ultrasonic and hypersonic frequencies (published 1934-1942)‚ and those on the effects produced by X-rays on infrared vibrations in crystals exposed to ordinary light. Raman was elected a Fellow of the Royal Society

What Is Photography? Photography is the art‚ science and practice of creating durable images by recording light or other electromagnetic radiation‚ either chemically by means of a light-sensitive material such as photographic film‚ or electronically by means of an image sensor. The result in an electronic image sensor is an electrical charge at each pixel‚ which is electronically processed and stored in a digital image file for subsequent display or processing. Typically‚ a lens is used to focus

Rappaport’s text is also a good reference for wireless signal propagation [Rap95]. 1 Antennas An antenna is an electrical conductor or a system of conductors that radiates/collects (transmits or receives) electromagnetic energy into/from space. An idealized isotropic antenna
