In many cases, math is used to place limitations on golf equipment, such as restricting the distance the ball will travel, as predicted by mathematical models. The Rules also place limits on a value called the coefficient of restitution, which measures the efficiency of the impact between a club and ball.

In their paper published in the journal Science, the group describes their experiments and what they observed. Marta Sales-Pardo with Universitat Rovira i Virgili offers a Perspective piece on the work done by the team in the same issue along with a short history of the theory behind the work and an explanation of why it matters in the modern world.

But a new paper shows that, because the most accurate models are generally more innovative and complex, they may suffer from a higher probability of error. Consequently, the most innovative and accurate models may not offer the best methods for making predictions, especially of rare, high-consequence events.

But crafting effective policy requires sound knowledge of vulnerable groups. And that is a daunting task since these populations—which include undocumented immigrants, homeless people or drug users—are usually hidden in the margins thanks to cultural taboos, murky legal status or simple neglect from society.

The seeds (coffee beans) from the plant of the same name are roasted and ground, allowing a flow of hot water to extract their soluble content. Undissolved solids are filtered from the dissolved particles, and the resulting liquid becomes the concoction that much of the population drinks every day.
