A model is a simplified representation of some aspect of the world. In what ways may models help or hinder the research for knowledge? A model by definition is “a schematic description of a system‚ theory‚ or phenomenon that accounts for its known or inferred properties and may be used for further study of its characteristics”(source) that implies that a model is supposed to be a helping hand while searching for knowledge in any subject. Sometimes however models can appear to be quite confusing

Theory Lissajous figures are patterns generated by the junction of a pair of sinusoidal waves with axes that are perpendicular to one another. Jules-Antione Lissajous studied these figures by producing sounds of different frequencies which were used to vibrate a mirror. A beam of light was then reflected from the mirror to produce trace patterns which were dependent on the frequencies. This setup used by Lissajous is similar to what is used today to project laser light shows. Today‚ Lissajous figures

Biography Name While there is a tendency to misspell his name as "Aryabhatta" by analogy with other names having the "bhatta" suffix‚ his name is properly spelled Aryabhata: every astronomical text spells his name thus‚[1] including Brahmagupta’s references to him "in more than a hundred places by name".[2] Furthermore‚ in most instances "Aryabhatta" does not fit the metre either.[1] [edit] Birth Aryabhata mentions in the Aryabhatiya that it was composed 3‚600 years into the Kali Yuga‚ when

commercial inverters a 12V DC input is popular because of the wide availability of powerful rechargeable 12V lead acid batteries which can be used as the DC power source. Output waveform: An inverter can produce square wave‚ modified sine wave‚ pulsed sine wave‚ or sine wave depending on circuit design. The two dominant commercialized waveform types of inverters as of 2007 are

+ c < 360o Angles A‚ B‚ C of a spherical triangle are measured by the corresponding dihedral angles of the trihedral angle A : B − OA − C ; B : A − OB − C and C : A − OC − B Napier’s Rules: 1. The sine of any middle part is equal to the product of the tangents of the adjacent parts 2. The sine of any middle part is equal to the product of the opposite parts *“co” indicates complement s i n ( middle ) = product of t a n ( adjacent ) s i n ( middle ) = product of c o s ( opposite ) - Angles

Exam Notes - PVL 3704 UNJUSTIFIED ENRICHMENT LIABILITY STUDY UNIT 1 - Overview Explain why there is a need for unjustified enrichment liability in any developed system of law? Liability for enrichment is necessary in any developed legal system. There are cases in which one person obtains assets belonging to another person in circumstances where there are no grounds for the transfer of such assets and where there is nothing to justify their retention by the receiver.

Aryabhata [pic] Statue of Aryabhata on the grounds of IUCAA‚ Pune. As there is no known information regarding his appearance‚ any image of Aryabhata originates from an artist’s conception. Aryabhata (IAST: Āryabhaṭa; Sanskrit: आर्यभटः) (476–550 CE) was the first in the line of great mathematician-astronomers from the classical age of Indian mathematics and Indian astronomy. His most famous works are the Aryabhatiya (499 CE‚ when he was 23 years old) and the Arya-siddhanta. |Contents
