Can you figure out the rule? Did you see the exponents pattern? Why do you make people look stupid? How do you investigate hypotheses? Do you seek to confirm your theory – looking for white swans? Or do you try to find black swans? I was startled at how hard it was for

The merging of two neutron stars was detected by gravitational waves and then by telescopes in all parts of the electromagnetic spectrum. This is a historic detection as it demonstrates: – the first gravitational waves detected from inspiraling neutron stars – the first joint observation by gravitational wave and electromagnetic wave astronomy – identification of

The nutrient content of food is declining. Is it because of soil depletion, selective breeding, or… something else? Watch my new documentary, VITAMANIA: I came across this story as I was making the film Vitamania. When you ask sellers of vitamins why you should take vitamin supplements even if you eat a healthy diet,

How do you measure big forces accurately? By calibrating your force transducer on the world’s biggest weight – 1,000,000 pounds of force. This machine ensures planes don’t break apart, jets provide required thrust, and rockets make it to their destination. Thanks to the people at NIST for showing me around: Rick Seifarth and Ben Stein.
All the large-scale structure in the universe may owe its existence to nothing.

We think of empty space as, well… empty,
Are all people on Earth really connected through just six steps? There’s much more science in this than I initially expected. It turns out ordered networks with a small degree of randomness become small-work networks. This is why your acquaintances turn out to be more important in job searches and finding new opportunities than close
Scientists are being inspired by nature to design the next generation of security devices. Arrays of nanoscale holes create beautiful reflected colours that are almost impossible to forge.

Complete unedited interviews: Trees can weigh hundreds or even thousands of tons, but where do they get this mass from? A few common answers are: the soil, water, and sunlight. But the truth is the vast majority of a dry tree’s mass comes from the air – it originated as carbon dioxide

How long is the coastline of Australia? One estimate is that it’s about 12,500 km long. However the CIA world factbook puts the figure at more than double this, at over 25,700 km. How can there exist such different estimates for the same length of coastline? Well this is called the coastline paradox. Your estimate
How does a transistor work? Silicon-28 sphere: This episode supported by We have looked at how a transistor works, the fundamental unit of classical computers, and how a quantum computer works in theory, taking advantage of quantum superposition to hold exponentially more information than classical computers. Now we look at the

Heisenberg’s uncertainty principle tells us that it is impossible to simultaneously measure the position and momentum of a particle with infinite precision. In our everyday lives we virtually never come up against this limit, hence why it seems peculiar. In this experiment a laser is shone through a narrow slit onto a screen. As the

Thank you for taking the time to attempt to understand it. I’ve been working on this for over six months over which time my understanding has improved. Quantum entanglement and spooky action at
The Higgs Boson is awesome but it’s NOT responsible for most of your mass! Thanks to for supporting this episode: The Higgs mechanism is meant to account for the mass of everything, right? Well no, only the fundamental particles, which means that electrons derive their mass entirely from the Higgs interaction but protons

Raw interviews: The question has arisen often enough that I thought I’d answer it. If you hold views that are consistent with the majority of the population, does that make you stupid? I don’t think so. Science has uncovered a lot of counterintuitive things about the universe, so it’s unsurprising that non-scientists hold beliefs
