Rocket (firework) century. Yet with all these drawbacks fireworks will continue to maintain their use as a traditional pastime with an ongoing history of nearly 5,000 years. Rocket (firework) A rocket is a pyrotechnic firework made out of a paper tube packed with gunpowder that is propelled into the air. Types of rockets include the skyrockets, which have a stick to provide stability during airborne flight; missiles, which instead rotate for stability or are shot out of a tube; and bottle rockets, smaller fireworks – 1½ in (3.8 cm) long, though the attached stick extends the total length to approximately 12 in
Utilitarian cake-cutting the partner that values it the most, as in the example above. Similarly, WUM divisions can be found by giving each fraction of the cake to the partner for whom the ratio formula_24 is largest. This process is easy to carry out when the value functions are piecewise-constant, i.e. the cake can be divided to a finite number of pieces such that the value density of each piece is constant for all people. What happens when the value functions are general (not piecewise-constant)? Then, the simple procedure of "give each piece to the one which wants it the most" does
