What is Quantum?

Discovery ·

2026/01/05

Quantum theory – our best understanding of the world at the smallest level – is famously weird and notoriously confusing. It’s a theory that seems to say particles can be in two places at once, or somehow “know” if you’re looking at them. Or at least, that’s what you might have heard. But is that really what quantum theory tells us about reality?To find out, presenter Marnie Chesterton travels to the birthplace of quantum theory: the remote, windswept island of Helgoland. Here, a century ago, a

"My ideas are often labelled as impossible, or useless, or both. Usually when people say that I'm on the right track." George Church is a geneticist, molecular engineer, and one of the pioneers of modern genomics. He's also someone who makes a habit of finding solutions to the seemingly impossible. Over the course of his career so far, George developed the first method for direct genomic sequencing, helped initiate the Human Genome Project, and founded the Personal Genome Project: making huge

Movies might have us believe that bomb disposal comes down to cutting the right wire. In fact, explosive devices are complex and varied - and learning how to dispose of them safely involves intense training, as well as the ability to stay calm under pressure. This was the world of Dr Gareth Collett, a retired British Army Brigadier General and engineer, specialising in bomb disposal; whose 32-year military career took him around the world, including heading up major ordnance clearance projects in

Many people will be familiar with Parkinson’s disease: the progressive brain disorder that causes symptoms including tremors and slower movement, leading on to serious cognitive problems.

The Animal Employment Agency

2025/11/24

We live in a time of automation and robotics; the machines run the factories, and AI will soon take all the jobs. And yet, even today, there are certain niche jobs where only an animal will do. Comedian and biologist Simon Watt is out to meet some of them, and the people who train them, study them, and love them. And he asks the key questions: HOW do they do what they do, and WHY, with all our ingenuity, haven't we invented anything that can compete with them?We start with a business of ferrets

Bodies

The London Anatomy Office accepts around 350 human bodies donated for medical research and education annually. You may imagine that these bodies are presevered in chemicals for medical students to study over weeks and months. And some are. But many are used - almost fresh - to train surgeons in the procedures which may one day save your life.Journalist Jenny Kleeman gains rare access to a surgical training course at Brighton and Sussex Medical School which uses these "fresh" donor bodies.

Chemical reactions are the backbone of modern society: the energy we use, the medicines we take, our housing materials, even the foods we eat, are created by reacting different substances together. If we zoom in, it’s the atoms within these substances that rearrange themselves to give rise to new substances with the properties we need.However, chemical reactions are far from perfect. They're often inefficient and their waste products can be harmful to the environment. Getting to grips with what goes

As a young man, traveling in Africa, Tim Coulson - now Professor of Zoology at the University of Oxford - became seriously ill with malaria and was told a second bout would probably kill him.

The celebrated primatologist Jane Goodall died last week at the age of 91. In tribute, we’re re-sharing this interview from 2020, where she reflects on the years she spent living with the wild chimpanzees in Gombe in eastern Tanzania and why she believes the best way to bring about change is to ‘creep into people’s hearts’.

Surgeons often have to deal with the consequences of violent attacks - becoming all too familiar with patterns of public violence, and peaks around weekends, alcohol-infused events and occasions that bring together groups with conflicting ideals.Professor Jonathan Shepherd not only recognised the link between public violence and emergency hospital admissions, he actually did something about it.As a senior lecturer in Oral and Maxillofacial Surgery in the early 1980s, Jonathan started looking into

Doyne Farmer is something of a rebel. Back in the seventies, when he was a student, he walked into a casino in Las Vegas, sat down at a roulette table and beat the house. To anyone watching the wheel spin and the ball clatter to its final resting place, his choice of number would’ve looked like a lucky guess. But knowing the physics of the game and armed with the world’s first wearable computer, which he’d designed, a seemingly random win was actually somewhat predictable.Doyne is an American

Claudia de Rham has rather an unusual relationship with gravity.While she has spent her career exploring its fundamental nature, much of her free time has involved trying to defy it - from scuba diving in the Indian Ocean to piloting small aircraft over the Canadian waterfalls. Her ultimate ambition was to escape gravity’s clutches altogether and become an astronaut, a dream that was snatched away by an unlikely twist of fate.However, Claudia has no regrets - and says defying gravity for much of her
