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

Grand canonical ensemble | Statistical mechanics | L-9

Grand canonical ensemble Grand canonical ensemble Microcanonical ensemble is a collection of independent assemblies in which energy (E), volume (V), and number of particles (N) remain constant. Canonical ensemble is a collection of independent assemblies in which temperature (T), volume (V), and number of particles (N) remain constant. It mean a microcanonical ensemble ⟶ Canonical ensemble, if we ignore the condition E = constant. Therefore the energy exchange takes place in this ensemble. Actually in chemical process, the number of particles N varies and it is very difficult to keep the number of particles constant in various phenomenon like radioactive decay process. Thus grand canonical ensemble is an ensemble in which the exchange of energy as well as the number of particles takes place with the heat reservoir. The grand canonical ensemble is a collection of essentially independent assemblies having the same temperature T, volume V, and a chemical potential µ.

Liquid helium as a Boson system | Statistical physics

Liquid helium as a Boson system Ordinary helium consists almost entirely of neutral atom of the isotope 2 He 4 . Since the total angular momentum of these atom is zero, so it follow the Bose-Einstein statistics. Properties of helium at low temperature The helium gas at atmospheric pressure condenses at 4.3K temperature into a liquid helium having critical temperature 5.2K, and the density of this liquid helium is very low (ρ = 0.124 g/cm 3 ). On further cooling the helium to about 0.82K, it does not freeze, and the liquid helium remains into liquid state up to absolute zero temperature i.e., T = 0K. It means the helium does not solidified at atmospheric pressure. To get the solid state of helium, it is subjected to an external pressure of at least 23atm. Phase transition of liquid He For He 4 in liquid phase, there is another phase transition (λ-transition), which divides the liquid state into two phases HeI and HeII. While liquefying He at

Rectangular Cavity Resonator | Microwave electronics

Rectangular cavity resonator A rectangular cavity resonator is a piece of rectangular waveguide of dimension a, b, and c. In figure a rectangular cavity resonator of sides a, b, c is shown. TE waves in a rectangular cavity resonator Here we will consider about two transverse electric waves, out of two one moves in +z direction and another in -z direction. Let the transverse component of electric field for TE waves propagating along +z direction be This equation give the resonant frequencies for different sets of m, n, p for different cavity modes. If two or more independent cavity modes have the same resonant frequencies then it is known as degenerate frequency. It is found that the modes TE 000 , TE 001 , TE 010 and TE 100 do not exist in the cavity. The lowest modes (dominant mode), which are possible in TE mode are TE 101 , TE 011 etc. The allowed frequencies corresponding to dominant modes is fundamental frequency. To know more about
