The story of the discovery that everything is made from atoms, one of the greatest scientific breakthroughs in history, and the brilliant minds behind it.
episodes:
01. The Clash of the Titans
The first of three programmes in which nuclear physicist Professor Jim Al-Khalili tells the story of the greatest scientific discovery ever – that everything is made of atoms.
As scientists delved deep into the atom, into the very heart of matter, they unravelled nature’s most shocking secrets. They had to abandon everything they believed in and create a whole new science, which today underpins the whole of physics, chemistry, biology and maybe even life itself.
The series tells a story of geniuses like Albert Einstein and Werner Heisenberg who were driven by their thirst for knowledge and glory. It is a story of false starts and conflicts, ambition and revelation, a story which leads us through some of the most exciting and exhilarating ideas ever conceived by the human race.
02. The Key to the Cosmos
The second in Professor Jim Al-Khalili’s three-part documentary about the basic building block of our universe, the atom. He shows how, in our quest to understand the tiny atom, we unravelled the mystery of how the universe was created. It’s a story with dramatic twists and turns, taking in world-changing discoveries like radioactivity, the atom bomb and the big bang. All this forms part of an epic narrative in which the greatest brains of the 20th century competed to answer the biggest questions of all – why are we here and how were we made?
03. The Illusion of Reality
The final part of Professor Jim Al-Khalili’s documentary series about the basic building block of our universe, the atom.
Al-Khalili explores how studying the atom forced us to rethink the nature of reality itself, encountering ideas that seem like they are from science fiction but in fact are a central part of modern science. He discovers that there might be parallel universes in which different versions of us exist and finds out that empty space is not empty at all, but seething with activity.
The world we think we know – the solid, reassuring world of our senses – turns out to be a tiny sliver of an infinitely weirder and more wonderful universe than we had ever conceived in our wildest fantasies.

Michael Mosley takes an informative and ambitious journey exploring how the evolution of scientific understanding is intimately interwoven with society’s historical path.
episodes:
01. What Is Out There?
Michael Mosley embarks on an informative and ambitious journey exploring how the evolution of scientific understanding is intimately interwoven with society’s historical path.
Michael begins with the story of one of the great upheavals in human history, how we came to understand that our planet was not at the centre of everything in the cosmos but just one of billions of bodies in a vast and expanding universe.
He reveals the critical role of medieval astrologers in changing our view of the heavens, and the surprising connections to the upheavals of the Renaissance, the growth of coffee shops and Californian oil and railway barons.
Michael shows how important the practical skills of craftsmen have been to this story and finds out how Galileo made his telescope to peer at the heavens and by doing so helped change our view of the universe forever.
02. What is the World Made Of?
In this episode, Michael demonstrates how our society is built on our search to find the answer to what makes up everything in the material world. This is a story that moves from the secret labs of the alchemists and their search for gold to the creation of the world’s first synthetic dye – mauve – and onto the invention of the transistor.
This quest may seem abstract and highly theoretical. Yet it has delivered the greatest impact on humanity. By trying to answer this question, scientists have created theories from elements to atoms, and the strange concepts of quantum physics that underpin our modern, technological world.
03. How Did We Get Here?
The question of our human origins is one of the most controversial science has wrestled with. This is the story of how scientists came to explain the beauty and diversity of life on earth, and reveal how its evolution is connected to the long and violent history of our planet. Featuring ocean adventurers, eccentric French aristocrats, mountain climbers, a secret Victorian publisher with 12 fingers, a ridiculed German meteorologist, and only a brief hint of Charles Darwin.
04. Can We Have Unlimited Power?
We are the most power-hungry generation that has ever lived. This film tells the story of how that power has been harnessed – from wind, steam and from inside the atom. In the early years the drive for new sources of power was led by practical men who wanted to make money. Their inventions and ideas created fortunes and changed the course of history, but it took centuries for science to catch up, to explain what power is, rather than simply what it does. This search revealed fundamental laws of nature which apply across the universe, including the most famous equation in all of science, e=mc2.
05. What Is the Secret of Life?
The story of how the secret of life has been examined through the prism of the most complex organism known – the human body. It begins with attempts to save the lives of gladiators in Ancient Rome, unfolds with the macabre work and near-perfect drawings of Leonardo in the Renaissance, through the idea of the ‘life force’ of electricity, to the microscopic world of the cell. It reveals how a moral crisis unleashed by work on the nuclear bomb helped trigger a great breakthrough in biology – understanding the structure and workings of DNA.
06. Who Are We?
We now know that the brain – the organ that more than any other makes us human – is one of the wonders of the universe, and yet until the 17th century it was barely studied.
The twin sciences of brain anatomy and psychology have offered different visions of who we are. Now these sciences are coming together and in the process have revealed some surprising and uncomfortable truths about what really shapes our thoughts, feelings and desires.
And the search to understand how our brains work has also revealed that we are all – whether we realise it or not – carrying out science from the moment we are born.

The explosive story of chemistry is the story of the building blocks that make up our entire world – the elements. From fiery phosphorous to the pure untarnished lustre of gold and the dazzle of violent, violet potassium, everything is made of elements – the earth we walk on, the air we breathe, even us. Yet for centuries this world was largely unknown, and completely misunderstood.
In this three-part series, professor of theoretical physics Jim Al-Khalili traces the extraordinary story of how the elements were discovered and mapped. He follows in the footsteps of the pioneers who cracked their secrets and created a new science, propelling us into the modern age.
Just 92 elements made up the world, but the belief that there were only four – earth, fire, air and water – persisted until the 19th Century. Professor Al-Khalili retraces the footsteps of the alchemists who first began to question the notion of the elements in their search for the secret of everlasting life.
He reveals the red herrings and rivalries which dogged scientific progress, and explores how new approaches to splitting matter brought us both remarkable elements and the new science of chemistry.

02. The Order of the Elements
In part two, Professor Al-Khalili looks at the 19th century chemists who struggled to impose an order on the apparently random world of the elements. From working out how many there were to discovering their unique relationships with each other, the early scientists’ bid to decode the hidden order of the elements was driven by false starts and bitter disputes. But ultimately the quest would lead to one of chemistry’s most beautiful intellectual creations – the periodic table.
03. The Power of the Elements
In the final part, Professor Al-Khalili uncovers tales of success and heartache in the story of chemists’ battle to control and combine the elements, and build our modern world. He reveals the dramatic breakthroughs which harnessed their might to release almost unimaginable power, and he journeys to the centre of modern day alchemy, where scientists are attempting to command the extreme forces of nature and create brand new elements.

Warming is warming, but another #winter is coming and in different parts of the world people will be freezing. Not far from here, #Russia continues to destroy Ukrainian infrastructure, and #Ukraine is preparing for another hardcore winter.
And this affects not only those fighting on the front lines, but also civilians in cities and rural areas.
That's why we want to add our micro contribution to winter aid and take up the production of chemical warmers, disposable and reusable.
- Reusable ones (sodium thiosulfate or sodium acetate with a mechanical trigger) in the form of larger and smaller pads, as well as inserts for vests (first aid for hypothermia).
- Disposable in the form of shoe and gloves inserts (catalytic iron oxidation),
We are looking for people willing to develop prototypes from publicly available materials, which we will test, publish documentation (under a C0 license) and put into production. We do not intend to sell it. We will collect donations to cover the costs, and the produced heaters will go to medical and aid groups."
