What is a sensor, and how does it work?
A sensor turns something real, such as heat or movement, into a number a computer can use. Learn the five steps inside one, and how to tell a good reading from a bad one.

What is a semiconductor?
A semiconductor conducts electricity only when you tell it to, which is what makes a switch with no moving parts possible. Here is how silicon becomes a chip.

The AI setting your power company should love
One default setting in the software that serves chatbots does not lower peak power, but it cuts how fast that power swings by up to 42.6 percent. A grid would need about a fifth less emergency reserve.

What is a qubit?
A qubit is the basic unit of a quantum computer, and it is stranger than a coin you have not looked at. Here is what superposition, phase and entanglement really mean.

What is a neural network?
A neural network is a stack of very simple steps whose settings are learned from data. Here is what a layer does, how training works, and the questions to ask before you trust one.

What is a large language model?
A large language model writes by guessing the next piece of text, over and over. Here is how it is built, what it is genuinely good at, where it fails, and how to get better answers out of it.

AI agents are being attacked four times faster than they are being defended
A review of 85 studies finds 47 papers on how to attack AI agents and 12 on how to defend them. The layer where agents actually act gets less than five percent of the research.

What is a drone, and what are drones used for?
A drone is an aircraft with nobody on board. This guide explains how one stays in the air, the main types, the jobs drones do well, and the rules you have to follow before you fly.

The camera that keeps watch for three months on one small battery
ETH Zurich built a sensor the size of a matchbox that watches all day, wakes only when something moves, names what it sees, and radios the answer. It runs for three months on a battery smaller than a phone's.

Explainer/Digital twins & Industry 4.0
What is a digital twin?
A digital twin is a live computer copy of a real machine or building, fed by its own sensors. Learn the three parts every twin needs and how to spot one that is only a shadow.
What is a data centre?
A data centre is the building your apps actually live in. Here is what fills the racks, why power and cooling can never pause, and how to judge whether a site is any good.
