Separation of Powers – Indian Context

• Three organs: Legislature, Executive, Judiciary

• Indian model = “separation of functions rather than of powers”
  • Overlaps & mutual checks (e.g.
  – Executive drawn from legislature
  – Judiciary empowered to review legislative & executive actions)

• Independence is partial/functional, not absolute

Astronomy, Cosmology & Theories of Solar-System Origin

• First mathematical, predictive heliocentric model: Nicolaus Copernicus
  • Published "De Revolutionibus Orbium Coelestium" in $1543$

• Big-Bang Theory (Universe began $13.8$ billion y ago) – Georges Lemaître (1931)

• Nebular (Kant-Laplace) Hypothesis
  • Immanuel Kant – $1755$; refined by Pierre-Simon Laplace – $1796$
  • Solar system formed from rotating cloud of gas & dust

• Planetesimal (Chamberlin–Moulton) Hypothesis – $1905$

Comparative Planetology

• Terrestrial / Interior planets: Mercury, Venus, Earth, Mars

• Jovian / Gas giants: Jupiter, Saturn

• Ice giants: Uranus, Neptune

• Revolution periods
  • Shortest: Mercury – $88$ days (also fastest orbital speed $\approx 47\ \text{km s}^{-1}$)
  • Longest: Neptune – $165$ yrs

• Rotation periods
  • Fastest: Jupiter
  • Slowest: Venus (retrograde)

• Size order (largest → smallest): Jupiter > Saturn > Uranus > Neptune > Earth > Venus > Mars > Mercury

Earth Geometry & Climate Zones

• Important latitudes
  • Equator $0^{\circ}$
  • Tropic of Cancer $23.5^{\circ} \text{N}$
  • Tropic of Capricorn $23.5^{\circ} \text{S}$
  • Arctic Circle $66.5^{\circ} \text{N}$
  • Antarctic Circle $66.5^{\circ} \text{S}$

• Zones
  • Torrid Zone: Between the two tropics (receives direct sun-rays)
  • North Temperate Zone: $23.5^{\circ}\text{N}$ → $66.5^{\circ}\text{N}$
  • South Temperate Zone: $23.5^{\circ}\text{S}$ → $66.5^{\circ}\text{S}$
  • Frigid Zones: Poleward of the Arctic & Antarctic Circles (e.g. area between Arctic Circle & North Pole)

• Length of $1^{\circ}$ latitude ≈ $111\,\text{km}$; longitudinal distance shrinks toward poles, max at equator $=111.32\,\text{km}$

• Great circles: Equator & every meridian (longitude)

• Prime Meridian $0^{\circ}$ – basis of GMT / UTC; $180^{\circ}$ meridian approximates International Date Line

Pre-Historic India & Iron Age

• Stone-Age chronology
  • Palaeolithic (Old) – $\sim5\times10^{5}$ BP → $12,000\,\text{BC}$
  • Mesolithic (Middle) – $12,000\,\text{BC}$ → $10,000\,\text{BC}$; microliths
  • Neolithic (New) – ushered pottery, settled agriculture

• Three-Age system (C. J. Thomsen): Stone → Bronze → Iron
  • Bronze Age in India represented by Indus Valley Civilisation (≈ $2500\text{–}1750\,\text{BC}$)

• Iron implements first appear during Neolithic–Megalithic overlap in South India

• Ceramics sequence (north Indian plains)
  $\text{Ochre-Coloured Pottery} \rightarrow \text{Painted Grey Ware} \rightarrow \text{Northern Black Ware} \rightarrow \text{Northern Black Polished Ware}$
  • Painted Grey Ware = hallmark of Early Iron Age

• Correct statements on Iron Age

  1. Surplus production allowed rise of larger settlements ✓

  2. Associated pottery = Painted Grey Ware ✓

  3. Indus civilisation NOT Iron Age ✗

Delhi Sultanate Highlights

• Dynastic sequence: Slave/Mamluk (1206-90) → Khalji (1290-1320) → Tughluq (1320-1414) → Sayyid (1414-51) → Lodi (1451-1526)

• Agra founded $1504$ by Sikandar Lodi; literature nickname “Gulrukhi”; early double-dome architecture (Mosque of Moth)

• "Group of Forty" (Chalisa/Turkan-i-Chahalgani)
  • Powerful Turkish slave-nobles of Iltutmish
  • Dominated politics during & after Razia Sultan’s reign
  • Abolished later by Balban (1266-87), who emphasised royal absolutism; introduced $Sijda$ & $Paibos$ court rituals

• Coins
  • $Tanka$ – silver; $Jital$ – copper

• Iqta system: Begun under Iltutmish (land-revenue assignment against military service)

Cell Biology & Physical States

• Integral membrane channel for water: Aquaporins
  • Tetrameric proteins; enable rapid, selective diffusion of $H_2O$ & small neutral solutes
  • Physiological basis of osmosis, turgor adjustments, renal concentration, etc.

• States & phase transitions
  • Solid ⇄ Liquid: Fusion/Melting & Solidification
  • Liquid ⇄ Gas: Vaporisation & Condensation
  • Solid ⇄ Gas: Sublimation & Deposition

• Extended states
  • Plasma – ionised gas at very high $T$, glows (e.g. neon lights, stars)
  • Bose-Einstein Condensate – near $0\,\text{K}$; predicted by S. N. Bose (1924), realised by E. Cornell & C. Wieman (1995, $\text{Rb}$) and W. Ketterle (1999, $\text{Na}$); Nobel Physics 2001

Indian Economy Basics

• Sectors by nature
  • Primary – agriculture, forestry, fishing, mining & quarrying
  – LFPR $\approx54.6\%$, GDP $\approx14.4\%$
  • Secondary – manufacturing, construction, electricity, water supply
  – LFPR $\approx24.3\%$, GDP $\approx31.5\%$
  • Tertiary / Service – trade, transport, communication, banking, education, health, hotels & restaurants (intangible outputs)
  – LFPR $\approx21.1\%$, GDP $\approx54\%$

• Micro-economics
  • Studies behaviour of individual decision units (consumers, firms, resource owners)
  • Key concepts: demand–supply, price formation, cost, elasticity
  • Classical contributors: Adam Smith ("Wealth of Nations"), Alfred Marshall; foundation for welfare analysis
  • Distinct from macro-economics (Keynes, aggregate income, inflation, unemployment)

Classical & Folk Dance

• 8 recognised classical dances (Sangeet-Natak Akademi)
  • Bharatanatyam, Kathak, Kathakali, Kuchipudi, Mohiniyattam, Odissi, Manipuri, Sattriya

• Kathakali (Kerala)
  • Textual treatises: "Balarama Bharatam" by Karthika Thirunal Rama Varma & "Hastalakshana Deepika" (hand-gesture canon)
  • Make-up & vesham (character types)
  – $Pacha$ (green heroic), $Kathi$ (knifed beard, villain), $Thadi$ (red/black beards), $Kari$ (she-demon), $Minukku$ (refined), $Pazhupu$ (sages)

• Incorrect folk-dance pairing
  • Paika is not from Kerala; practised in Odisha, Jharkhand, Chhattisgarh

• State folk samples
  • Maharashtra – Lavani, Koli, Tamasha, Dhangari-Gaja, Povada
  • Gujarat – Dandiya Raas, Garba, Tippani, Gop Raas, Bhavai
