Quantum computers: Computing the impossible

Quantum computers could one day solve some of the world’s toughest problems, and they’d do this by working completely differently to a regular computer. Information is stored in your laptop in bits. Every bit is either a one or a zero: up or down. But quantum computers are made of qubits. Unlike bits, qubits can […]

The dark side of electronic waste recycling

– [Jim] They had a place where they’d store it right under our noses. They just thought they could get away with it forever, and they could have if it hadn’t been for those trackers. (Jim laughs) – [Reporter] Right now, you’re watching this on an electronic device. Do you ever think about where it’ll […]

Hello World — Programming on Quantum Computers Ep 3

– Call got get counts and pass in our circuit. And there it is; that’s the result of executing our quantum circuit. (funky music) Hello, everyone. Welcome back to Coding with Qiskit. So traditionally when we learn new programming languages, the first application that we write is what’s called the Hello World application. And the […]

Electric Vocabulary

I’m going to try to shine a historical light on our language, and tell you a story about the electric vocabulary. It all begins over 2,600 years ago. An ancient Greek, called Thales of Miletus, is thought to be the first person to observe what we would today call electrical phenomena. He discovered that a […]

Computer Color is Broken

If you put a colorful image into photoshop or instagram and blur it, you’ll see a weird, dark boundary between adjacent bright colors. Yuk! In the real world, out of focus colors blend smoothly, going from red to yellow to green – not red to brown to green! This color blending problem isn’t limited to […]

The Pain of Electricity (AC versus DC)

Hi. One of the common questions is that: what kind of electricity hurts more? AC (alternating current) or DC (direct current)? So, I’m going to measure the electricity pain level on a human’s body, which is myself. But first, let’s measure the resistance of the skin on tongue and fingers for reference. So first, let’s […]

Quantum Computers Animated

Well we use the word in reference to the laws of physics that apply in the microscopic world at the level of individual atoms, individual electrons, and elementary particles … where physics is qualitatively different than what we experience in our everyday lives. Have you ever been to the beach and you see waves coming […]

Why 3 Phase AC instead of Single Phase???

Hi. In my last video, I talked about how Tesla won the AC-DC battle against Edison. But then he shoved three-phase AC down our throats instead of single-phase AC. Edison: “Oh no, he didn’t. He always asked for too much” Ah, get lost Eddy! Obviously Tesla had a good reason. What is a three-phase AC? […]
