When you go down a curved slide, your velocity is constantly changing direction. Otherwise, you'd either fly off the slide or fall straight through. This means that your body is constantly accelerating, as you can see in this simulation. ⁠ ⁠

Newton's second law tells us that force is mass times acceleration. So when would you feel the most force?⁠ Check it out here.

Using computer science, can you always win at 20 questions? With a perfectly-designed algorithm, you could reduce the number of possibilities by half with each question. With such an algorithm, you could always win, even if you started with 2^20 ≈ 1 million possibilities. ⁠ ⁠

Such a mathematically perfect algorithm isn't necessarily practical. Even without mathematical perfection, the right strategy is to ask questions that split the field mostly in half. With this strategy, a well-designed algorithm can easily guess correctly any of the ~200,000 actors on Wikipedia.⁠

Brilliant's newest computer science course is Search Engines. In this interactive course you'll learn how to build a search engine and master the search algorithms that enable the internet we use today.


Along the way you'll add features to a specialized search engine we built for the course. Sherlock searches through the 4 novels and 47 short stories by Sir Arthur Conan Doyle, featuring the great detective Sherlock Holmes.

Building a searchable data structure for all that information is tricky, especially for the complex queries required to solve the mysteries you'll encounter.
