I am a mathematician and I like action movies Particularly Die Hard is one of my favourites You know action movies and there is one which has a couple of maths problems and one very famous one is In this clip, so just play the clip and then we talk about a little bit Careful don't open it. What I gotta open and it's gonna be alright I told you not... Read More
Questions & Answers
Q: How do you solve the water jug problem in Die Hard using the 5gallon and 3gallon jugs?
The solution involves filling the 5gallon jug first, pouring from it to fill the 3gallon jug, emptying the 3gallon jug, and transferring the remaining water from the 5gallon jug to the 3gallon jug to reach a measurement of exactly four gallons.
Q: What is the significance of the billiards table analogy in solving the water jug problem?
The billiards table analogy helps in understanding the relationship between the jug volumes and the dimensions of the table. By shooting a billiards ball at certain angles, it reflects off different sides of the table, indicating the steps to follow in the jug problem solution.
Q: Can the solution be applied to other measurement goals, such as one gallon or two gallons?
Yes, the solution can be adjusted for different measurements. By following the same pouring and transfer steps, the solution can be tailored to achieve different gallon measurements.
Q: Are there any alternative solutions to the water jug problem?
Yes, the content also explores a second solution to the water jug problem, which involves starting the pouring process differently. This solution works in a similar manner but takes a bit longer to achieve the desired measurement.
Summary & Key Takeaways

The content discusses the water jug problem posed in the movie Die Hard, where the goal is to measure exactly four gallons of water using a 5gallon and a 3gallon jug.

The mathematician explains a stepbystep solution to the problem, starting with filling the 5gallon jug, transferring water between the jugs, and pouring to achieve the desired measurement.

Additionally, the mathematician explains a mathematical billiards approach to solve the problem and how it relates to the volumes of the jugs.
