This study note covers the equation, units and the gas constant R, how it combines Boyle's, Charles's, Gay-Lussac's, and Avogadro's laws, worked examples, useful variations (molar mass, density, combined gas law), and where the ideal gas law breaks down.
- [Sine Cosine Tangent](https://gauravtiwari.org/study-notes/sine-cosine-tangent/): Sine, cosine, and tangent are the three fundamental trigonometric ratios. This study note covers SOH-CAH-TOA, worked examples, special triangles (30-60-90 and 45-45-90), the unit circle extension to all angles, radians vs degrees, and the key identities (Pythagorean, quotient, reciprocal, co-function, even/odd, sum-and-difference).
- [Exponential Function](https://gauravtiwari.org/study-notes/exponential-function/): An exponential function f(x) = a^x has the variable in the exponent. This study note covers the definition, the difference between growth (a > 1) and decay (0 < a < 1), the algebraic properties, why the number e is the natural base, doubling time and half-life formulas, and the dozens of real-world processes (compound interest, radioactive decay, viral spread, RC circuits) that follow exponential dynamics.
- [Immune System](https://gauravtiwari.org/study-notes/immune-system/): The immune system is the body's defense against pathogens and transformed cells. This study note covers the two branches (innate vs adaptive), the cells involved (phagocytes, NK cells, T cells, B cells), antibodies and their five classes, immunological memory and vaccination, self-tolerance mechanisms, and the failure modes (immunodeficiency, allergies, autoimmunity, sepsis, cancer immune evasion).
- [Mean Median Mode](https://gauravtiwari.org/study-notes/mean-median-mode/): Mean, median, and mode are the three classic measures of central tendency in statistics. This study note covers how to calculate each, when to use which, what their relative positions tell you about the shape of a distribution (skewness), the weighted mean, and the practical rules of thumb for reporting central tendency on real data.
- [Electronegativity](https://gauravtiwari.org/study-notes/electronegativity/): Electronegativity is how strongly an atom pulls bonded electrons toward itself. This study note covers the Pauling scale, the two periodic-table trends (across a period, down a group), how to use electronegativity differences to predict bond type (nonpolar, polar, ionic), polar molecules and dipoles, and why electronegativity is the single most useful concept in introductory chemistry.
- [Cell Cycle](https://gauravtiwari.org/study-notes/cell-cycle/): The cell cycle is the ordered sequence a eukaryotic cell goes through from its birth to its division. This study note covers the four phases (G1, S, G2, M), their relative durations in a typical 24-hour human cycle, the three major checkpoints (G1/S restriction point, G2/M, spindle assembly), the cyclin/CDK regulatory engine, the G0 resting state, and how cell-cycle dysregulation is the central problem in cancer.
- [Osmosis](https://gauravtiwari.org/study-notes/osmosis/): Osmosis is the passive movement of water across a semipermeable membrane from low solute to high solute concentration. This study note covers the precise definition, why water moves (kinetic theory), tonicity vocabulary (hypotonic, hypertonic, isotonic), osmotic pressure and the van't Hoff equation, biological roles (cell volume regulation, plant turgor, kidney function, IV fluids), and the difference between osmosis and diffusion.
- [Meiosis](https://gauravtiwari.org/study-notes/meiosis/): Meiosis is the specialized cell division that produces 4 genetically unique haploid gametes from 1 diploid parent cell. This study note covers why meiosis exists, the two divisions (meiosis I reductional, meiosis II equational) with all phases, the three sources of genetic variation (crossing over, independent assortment, random fertilization), the meiosis vs mitosis comparison, and what happens when meiosis goes wrong (nondisjunction, Down syndrome, Klinefelter syndrome).
- [Glycolysis](https://gauravtiwari.org/study-notes/glycolysis/): Glycolysis is the first stage of cellular respiration — the universal metabolic pathway that splits one glucose into two pyruvate molecules in the cytoplasm without requiring oxygen. This study note covers the 10 enzymatic steps split into investment and payoff phases, the net 2 ATP and 2 NADH per glucose, what happens to pyruvate aerobically vs anaerobically, and why glycolysis is the most universally conserved pathway in biology.
- [Krebs Cycle](https://gauravtiwari.org/study-notes/krebs-cycle/): The Krebs cycle (citric acid cycle, TCA cycle) is the second stage of aerobic cellular respiration. This study note covers where the cycle sits in the bigger picture of respiration, the per-acetyl-CoA inputs and outputs (3 NADH, 1 FADH2, 1 GTP, 2 CO2), the eight enzymatic steps, why the cycle's intermediates also feed biosynthesis, and how it is regulated by energy demand.
- [Golden Ratio](https://gauravtiwari.org/study-notes/golden-ratio/): The golden ratio φ = (1 + √5) / 2 ≈ 1.618 is an irrational number with surprising mathematical depth. This study note covers the definition, key properties (self-similarity, reciprocal, continued fraction), the Fibonacci connection, the golden rectangle and spiral, where φ actually appears in nature (phyllotaxis, pentagonal symmetry, quasicrystals), and the famous claims about art and architecture that don't survive scrutiny.

- [Avogadro’s Number](https://gauravtiwari.org/study-notes/avogadros-number/): Avogadro's number is the bridge between the atomic and the everyday — 6.022 × 10²³ particles in one mole. This study note covers the exact value, what a mole is, how to use it in mass-to-moles-to-particles calculations, molar mass and the periodic table connection, the historical story from Avogadro to modern silicon-sphere measurements, and the 2019 SI redefinition that fixed N_A as an exact constant.
- [Slope-Intercept Form](https://gauravtiwari.org/study-notes/slope-intercept-form/): Slope-intercept form y = mx + b is the most useful way to write the equation of a straight line. This study note covers what m (slope) and b (y-intercept) mean, how to plot a line in two steps, conversions from standard form and point-slope form, special cases (horizontal, vertical, parallel, perpendicular lines), and why this one form underlies every linear model in physics, economics, and statistics.
