A gecko’s ability to climb a vertical surface relies solely on the geometrical makeup of hairs on each toe. In a grid-like pattern, each toe contains microscopic hairs called setae. These setae, once again magnified, split into triangular shaped hairs called spatulae at the tips. Millions of spatulae come into close contact to the surface, as each hair fits into the “ridges” and “peaks” of the molecular landscape. In both the surface, and the hairs of the gecko, protons and electrons continually move within the molecules. However once in extremely close proximity, an induced dipole occurs, and the molecules become either partially negative or positive. These attractions, when magnified by the millions of other spatulae contacting the surface, create stability for the gecko to climb the wall. Moving its feet parallel to the surface, the gecko is able to easily adhere to the surface, and then quickly detach its feet by pulling away perpendicularly from the surface - or at ...

- ... Hence microfilled composites aren’t used in posterior restorations and not commonly used today. Hybrid Composites are made up of resin matrix and 60% or more composes of different composition and size of glass particles which range from 0.6-1µm and also containing colloidal shaped silica particles with 0.04µm diameter. Hybrid composites reduced polymerisation shrinkage, low water absorption, similar wear and thermal expansion co efficient to tooth structures, it has good polishability and also able to mimic tooth structure in terms of opacity and colour....

- Waldner 6 The phrase “Biblically Inspired” makes people believe that the movie will be the same as the story in the Bible, when, upon examination, the movie is found to contain little from the Bible. Therefore, Noah creates an unrealistic expectation of the Bible, creating an entirely alternative story, hiding the lies behind the “Biblically inspired” phrase. So what sort of false reality of the Bible does Noah create, exactly. Well, the film represents the story of Noah, which is a significant story to the Christian faith, as a hate-filled, selfish, and magical story, and also makes the God of Noah’s story seem disconnected from His creation....

Therefore, as music possesses the ability to motivate individual’s to express particular emotions, it more importantly displays its message in the masses of society further leading to cultural movements.

- Bible as the Inspired Word of God The Bible is the work of various authors, who lived in different continents and wrote in different eras. Furthermore, much of the text does not claim to have been 'dictated' by God and is not always God speaking to people. In parts it consists of people speaking to God, as in the Psalms, and people speaking to people, as in the New Testament letters written by Paul. In light of this, some maintain that it is not possible to treat the Bible as a book of divine oracles, delivered once by God and recorded by its authors through divine inspiration, since biblical authors were products of their time and subsequently their understan...
