चार महीने का बच्चा कैसे बना अरब़पति

चार महीने का बच्चा कैसे बना अरब़पति? जन्म के सिर्फ चार माह बाद यदि कोई बच्चा अरबपति बन जाए तो इसे उसकी किस्मत ही कहेंगे। भारत के एकाग्रह रोहन मूर्ति नाम के बच्चे की किस्मत कुछ इसी प्रकार चमकी है। देश की दूसरी सबसे बड़ी आइटी कम्पनी इंफोसिस के फाउंडर नारायण मूर्ति ने सोमवार अपने चार महीने के पोते एकाग्रह मूर्ति को 240 करोड़ रूपए के शेयरों की हिस्सेदारी का तोहफा देकर उसे शायद देश का सबसे कम उम्र का अरबपति बना दिया है। BSE की फाइलिंग के अनुसार इंफोसिस में अब एकाग्रह रोहन की 15 लाख शेयरों की हिस्सेदारी हो गई है। इसका मतलब अब एकाग्रह रोहन इंफोसिस का 0.04% का हिस्सेदार है। शेयरों के स्थानान्तरण के बाद नारायण मूर्ति के पास कम्पनी के कुल शेयरों का 0.36% हिस्सा बचा है। जिस समय नारायण मूर्ति द्वारा अपने पोते को शेयर देने की खबर बाई उस समय इंफोसिस के शेयरों में गिरावट देखने को मिल रही थी। एकाग्रह रोहन, नारायण मूर्ति तथा सुधा मूर्ति के बेट रोहन मूर्ति और उनकी पत्नि अर्पणा कृष्णन का बेटा है। आपको यह पता होगा कि नोरायण मूर्ति ने अपनी पत्नि सुधा मूर्ति से 10 हजार रूपए उधार लेकर 1981 में इंफोसिस क

Fermi Dirac Statistics

Fermi Dirac Statistics

  • It is applied to Fermions or Fermi particles, i.e. indistinguishable particle with half integral spin.
  • Particles are indistinguishable from each other.
  • Each cell or sublevel may contain 0 or 1 particle i.e., gi,  >> ni
  • Total number of particles of system remain constant, n = Σni  = constant
  • Sum of energies of all the particles in the different groups taken together i.e., total energy of the system remain constant E = Σniεi  = constant

  • Consider a system of n independent identical particles having half integral spin.
  • These particles be divided into quantum groups or levels such that
  • Energy levels    ε1, ε2, ε3, ...εi 
  • Degeneracies    g1, g2, g3, ...gi 
  • Occupation number    n1, n2, n3, ...ni 

  • Consider a box, divide it into gi  sections, distribute ni particles among them.
  • Number of ways to put first particle in any one of the iih  level = gi 
  • Number of ways to put second particle in the remaining (gi  – 1) state = (gi  – 1)
            …     …     …     …     …     …
  • Total number of ways to distribute ni  particles in gi  states = gi (gi  – 1) (gi  – 2) ... (gi – ni + 1)

  • Sterling approximation log x! = x log x – x

Electric field due to circular loop of charge | Electromagnetics

Electric field due to circular loop of charge Electric field The space around a charged particle in which another charge experience a force is known as electric field. The source of electric field is either a charge or a time varying magnetic field. If the value of electric field does not change with time, then it will be uniform electric field, otherwise it will be non-uniform electric field. Electric field due to circular loop of charge If λ is linear charge density, then the charge on d l dq = λ d l      ⇒     dq = (q / 2πa) d l Electric field at P due to charge dq Special cases When P lies at the centre of the loop i. e., r = 0, then E = 0 When P lies very far from the centre of the loop i. e., r >> a, then E = kq / r 2 In this case circular loop behaves as a point charge.

Constraints | Classification and Properties of constraints | Classical mechanics

Constraints and its classification Constraints force Constraints are restrictions that limit the motion of the particles of a system. Physically constrained motion is realized by the forces which arise when the object in motion is in contact with the constraining surfaces or curves. These forces are called constraint forces. Properties of constraints force They are elastic in nature and appear at the surface of contact. They are so strong that they barely allow the body under consideration to deviate even slightly from a prescribed path or surface. This prescribed path or surface is called a constraint. The effect of constraint force is to keep the constraint relations satisfied. Classification of constraints           Scleronomic and Rheonomic This classification is based on time. The constraints are said to be scleronomic constraints, if the constraint relations do not explicitly depend on time. But if the constraint relations explicitly depend on ti

Advantage and Disadvantage of Power Electronics

Advantage and Disadvantage of Power Electronics Advantage of Power electronics Power electronics is used in space shuttle power supplies Since there is very low loss in power electronic devices so its efficiency is very high. Power electronic converter systems are highly reliable. Since there is no moving parts in power electronic systems so it has long life and also its maintenance cost is very less. The power electronic systems has fast dynamic response in comparison to electromechanical converter systems. Since the power electronic system has small size and also it has less weight so they occupy less floor space and hence their installation cost is also less. Now these days power equipments are being mostly used, so power semiconductor devices are being produced on a large scale, resulting in lower cost of converter equipment. Power electronics are used in computer and office equipments. It is used in uninterruptible power supplies. Power
