From Pringles® to Space  Unveiling the Mysteries of Hyperbolic Paraboloids and Magic Linear Structures
It turns out that this iconic snack isn't just a happy accident – it's actually a product of mathematics, specifically a secondorder surface type known as the hyperbolic paraboloid, which happens to resemble a "saddle". So, let's saddle up and explore the mathematical magic behind Pringles®!

F4 Phantom vs. Reinforced Concrete Block
In 1988, the US government wanted to check how strong the reinforced concrete used in nuclear reactors was. They decided to answer the question "Will it withstand, for example, a point hit by an airplane?" directly, and launched the F4 Phantom fighter into the concrete block at a speed of 500 mph (804.67 km/h). What is the result?

A stressstrain instant in your career
At some point in your career, you may be asked to develop a stressstrain law for a new material. If so, it is important to make sure that the stressstrain law satisfies two conditions.
