Imagine sitting on a plane flying thousands of kilometers above the Earth. There may be nothing visible below except clouds and ocean, yet the aircraft is following a precise route toward an airport that could be on the other side of a continent. It knows its position, its altitude, its direction and, importantly, where it needs to go next. But how? The answer is surprisingly complex. Airplanes don't rely on a single navigation technology. Modern aircraft combine satellite signals , onboard sensors, computers, radio systems , digital maps and human decision-making to navigate through the sky. And unlike what you might expect, GPS is only one piece of the puzzle. From Looking at the Ground to Navigating by Computer Early aviation was much more dependent on what pilots could actually see. A pilot could use roads, rivers, coastlines, mountains, towns and other landmarks to estimate their position. This method worked reasonably well in good weather, but it obviously had limitations....

Microsoft Copilot is about to become much more than an AI chatbot. On September 25, 2026, Microsoft announced a major redesign of Copilot, bringing together AI chat, Office, app creation and autonomous AI agents in one experience. The announcement introduces three major parts: Home, Code and Autopilot . And the idea behind them is simple: instead of only asking Copilot questions, users will increasingly be able to give it work to do . Copilot Gets a New Home The first major change is simply called Home . It becomes the new starting point for Copilot, bringing different ways of using the AI together in one place. Users can chat with Copilot as before, but they can also use Cowork to delegate more complicated jobs. Instead of saying: "Summarize these documents." You could give Copilot a bigger objective and let it work through the different steps. Microsoft gives examples such as preparing an RFP response, creating a launch package, preparing a customer briefing or putting tog...

Artificial intelligence is moving beyond systems that simply answer questions or generate content. A new generation of AI can interpret goals, make decisions, use tools, and carry out multiple steps with limited human intervention. These systems are known as AI agents . From managing business processes to researching information, writing code, controlling software, and interacting with digital services, AI agents are designed to do more than produce a single response. But how do they actually work?

Wireless charging has changed the way we power smartphones, smartwatches, earbuds, and other electronic devices. Instead of connecting a cable directly to a device, users can simply place it on a compatible charging pad or stand. But how can electricity travel from a charging pad into a device without a physical connection? The answer lies in electromagnetic induction , a technology that allows electrical energy to be transferred between two coils. Although the concept may seem futuristic, the principles behind wireless charging have existed for more than a century.

The QWERTY keyboard layout is one of the most recognizable interfaces in modern technology . Found on computers, laptops, smartphones, tablets, and countless other devices, its distinctive arrangement of letters has become so familiar that most people rarely question why the keys are positioned the way they are. QWERTY has a fascinating history that began with mechanical typewriters in the 19th century. What started as a solution to the technical limitations of early typing machines eventually became a global standard that continues to influence how people interact with technology today. What Is QWERTY? QWERTY is a keyboard layout named after the first six letters on the top row of the alphabetic keyboard: Q, W, E, R, T, and Y . The layout organizes letters, numbers, punctuation marks, and other keys into a standardized arrangement. While modern keyboards are electronic and no longer face many of the mechanical limitations of early typewriters, the basic QWERTY arrangement has rema...

A VPN has become one of the most popular tools for improving online privacy and securing internet connections. Whether you're using public Wi-Fi , browsing from home, or traveling , a VPN can add an extra layer of protection between your device and the internet. But what exactly is a VPN, how does it work, and what does it actually protect? In this guide, we'll explain what a VPN is, how VPN encryption works, its main benefits and limitations, and when using one makes sense .
