Abha Shankar 6 years, 5 months ago

The replacement model supports the view that the modern human beings in a single region, i.e. Africa. In support of this view,most of the scholars tried to correlate the anatomic and genetic similarity of modern humans. It indicates that their ancestors belonged to one region and from where they migrated to different parts of the world. The Regional continuity Model supports the view that modern humans originated at several regions across Africa,Asia and Europe. To support their view the scholars tried to correlate the anatomical differences of modern humans which indicate that they belonged to different regions

Define strategy of approximation

Posted by Shruti Jha 6 years, 5 months ago

CBSE > Class 11 > Physics

3 answers

Ranjeet Kumar 6 years, 5 months ago

The strategy orlf approximation turned out to be very successful. (i) Most observed phenomena in daily life are rather complicated manifestations of the basic laws. (ii)Scientists recognised the importance of extracting the essential features of a phenomenon from its less significant aspects. (iii)It is not practical to take into account all the complexities of a phenomena in one go. (iv)A good strategy is to focus first on the essential features of a phenomena and discover the basic principles and then introduce corrections to build a more refined theory. (v)During study for free fall under gravity we assume air resistance to be zero.Similarly in mechanics we take moving objects as point objects.

3Thank You

Ranjeet Kumar 6 years, 5 months ago

The strategy of approximation can be explained as - [1]Speculation (talking about future results of experiments) and conjecture ( a approximation) have an important role to play during the procedure of scientific method of describing a phenomena, but must be verified by experiments. For example (i) The circular orbits as assumed by Nicolaus Copernicus in the heliocentric theory was replaced after certain inspections and experiments carried by Johannes Kepler. (ii)Paul Dirac in 1930, theoretically introduced the concept of antiparticle,which was later experimentally verified by Carl Anderson. [ii] Sometimes physical constants had to be assumed , their values later experimentally verified. The Universal gravitational constant G and constant in the coulombian force 1/4πε_0 were earlier assumed and later evaluated by using torsion balance.

Approximation theory is a branch of mathematics, a quantitative part of functional analysis. Approximation usually occurs when an exact form or an exact numerical number is unknown.
