Whether you are calculating the speed of a car, estimating how far a sound wave has travelled, or working out how long it takes light to reach the Earth, the relationship between speed, distance and time is used in many … Read more › The post Python Challenge – Speed, Distance & Time Calculator first appeared on 101 Computing .
Have you ever wondered how a computer keeps track of all the coloured squares on a Rubik’s Cube? Although the puzzle looks complicated, each face of the cube can actually be stored using a simple 3 × 3 two-dimensional (2D) … Read more › The post Rubik’s Cube Challenge first appeared on 101 Computing .
Imagine being tasked with exploring a vast underground cave system where no human has ever been before. Narrow passages, uneven ceilings, jagged rocks and sudden drops make it far too dangerous for people to enter. Instead, scientists use autonomous drones … Read more › The post Autonomous Cave Exploration Drone Algorithm first appeared on 101 Computing .
Long before radios and GPS, sailors relied on teamwork, experience and a good rhythm to keep a ship moving. One tradition that became famous around the world was the sea shanty. These songs were sung by crews as they hoisted … Read more › The post Sailing the Seven Seas (Python Challenge) first appeared on 101 Computing .
Finding the shortest route between two places might sound like a simple task, but when a network contains hundreds or even millions of possible paths, computers need an efficient way to decide which route to follow. This is where search … Read more › The post A* Short Path Algorithm Interactive Task first appeared on 101 Computing .
Every time you use a sat nav, plan a journey on a map app, or search for the fastest route across a transport network, you are using ideas from graph theory. A road map can be represented as a graph: … Read more › The post Dijkstra Short Path Algorithm Interactive Task first appeared on 101 Computing .
Not every digital image is stored as a collection of coloured pixels. While photographs and pixel art are usually saved as bitmap images, many logos, icons, maps and illustrations are created using a completely different method called vector graphics. Instead … Read more › The post Vector Based Graphics Editor first appeared on 101 Computing .
Every photo, icon, emoji and piece of pixel art you see on a computer has to be stored digitally. But have you ever wondered how a computer can save an image using nothing more than 1s and 0s? One of … Read more › The post Bitmap Image Simulator first appeared on 101 Computing .
Have you ever wondered how your computer or smartphone stores music, podcasts or voice recordings? Although sound travels through the air as a continuous (analogue) wave, computers can only store digital data made up of 1s and 0s. So how … Read more › The post Sound Sampling Simulator first appeared on 101 Computing .
