combinations

Physicists say they've found evidence in data from Europe's Large Hadron Collider for three never-before-seen combinations of quarks, just as the world's largest particle-smasher is beginning a new round of high-energy experiments.  The three exotic types of particles – which include two four-quark combinations, known as tetraquarks, plus a five-quark unit called a pentaquark – are totally consistent with the Standard Model, the decades-old theory that describes the structure of atoms.In contrast, scientists hope that…

A concise description on combinations and permutations and their differencesPhoto by Jean-Louis Paulin on UnsplashCombinations and permutations are common throughout mathematics and statistics, hence are a useful concept that us Data Scientists should know.In this post, I want to discuss the difference between the two, difference within the two and also how one would calculate them for some given data.The main thing that differentiates between permutations and combinations is that for the former order does matter but it…

It’s hard to imagine that three random words have the power to both map the globe and keep your private data secure. The secret behind this power is just a little bit of math. What3words is an app and web-based service that provides a geographic reference for every 3-meter-by-3-meter square on Earth using three random words. If your brain operates more naturally in the English measurement system, 3 meters is about 9.8 feet. So, you could think of them as roughly 10-foot-by-10-foot squares,…
