WorldThe Science of CookingRun a real stove: bring water to the boil and read the plateau, seal a cooker for dal, take the egg out before the yolk sets, brown paneer without burning it, split milk with lemon, keep the vitamin in the spinach, rise a dough, beat the danger zone, pour caramel in its window, and build a thali that meets a thirteen-year-old's needs
WorldHeat & Kinetic TheoryCool nitrogen to −190 °C, count its molecules hitting a wall, and fly a hot-air balloon on the difference in density
