And one thing this has taught me is that physics itself is still incomplete, there are many mysteries in the universe we still don't understand. This makes me wonder, in the future, will we ever be able to complete physics, and understand everything in the universe? And if not, what's stopping us?

The Fascinating World of Fungi. Get yourself 20% off a Brilliant premium subscription here: https://brilliant.org/dos/ In this map of fungi we learn everything we can about fungi in about 20 minutes. They are hugely underappreciated as they are an entire kingdom of life, as rich as plants and animals, and we use them so much in our day to day lives beyond eating their mushrooms. They are really important for medicine (antibiotics, statins and many more) and nearly all plants on Earth rely on fungi to live. Amazing stuff. I learned so much making this video!

Today is July the 3rd. And for us humans on earth, today is the day that we're the furthest away from the sun that we’ll be all year. So why is it so warm? Where I live, it's summertime and we've just gone through our first heatwave of the year, and you'd think it would be cold when you're far away from the sun and warm when you're close to the sun. On the 3rd of January. But it's the other way around. This can all be explained by the fact the earth has a tilted axis like my head. Right now, in the summer, we're tilted towards the sun, so we're getting more heat from it. Just to give you some concrete numbers. We're getting about 7% less energy from the sun by being far away now compared to January the 3rd, when we're closer, we get 7% more. But the difference in tilt means tilting towards the sun gives about 500 percent as much energy as being tilted away. For here in London. It obviously varies depending on how high up or down in latitude you are. And obviously everything's flipped for the southern hemisphere because it's their winter at the moment, so it does kind of make sense for them. But it's interesting. This combination means that in the Northern Hemisphere we have slightly longer summers and slightly shorter winters, whereas in the southern hemisphere it's the opposite way around. They have slightly shorter summers and slightly longer winters. So in conclusion, as they always say, nobody cares how far away you are from the sun. If you've got a wonky axis.

I recently got to visit the anti-matter factory at CERN. This is the only place in the world where they've managed to make antihydrogen. This is antihydrogen. It's an atom of antimatter made of an anti electron, also known as a positron and an antiproton in the middle. This is arguably the most expensive material in the world, costing an estimated thousand trillion dollars per gram. They have to be incredibly careful with this antimatter, because it's a kind of opposite matter to what our world's made from. So if the antimatter touches literally anything, it will annihilate, immediately turning all of its mass into pure energy. Fortunately, antihydrogen is slightly magnetic, so the scientists at CERN can stop it from touching anything by hovering it in a magnetic field called a penning trap. After the Big Bang, half of the universe was made of anti-matter and the other half normal matter. According to many of our best theories of cosmology. But today we don't see any antimatter in the universe and is a mystery where it went. So making anti-matter in the lab means we can study its properties, which might give us some clues about what happened to half a universe’s worth of anti-matter. This experiment I visited tested which direction antihydrogen would fall in gravity. Would it fall down like matter? Or because it's anti-matter? Would it fall up? Turns out it did fall down slightly. Disappointing, because now I can't invent hoverboards. But it's really cool for me to actually see the actual experiment from when all of that news came out. So it's pretty cool to be in an anti-matter factory.

It might look like I'm using my Jedi powers to control a droid, but in reality, I'm at CERN in Switzerland and I'm in their robotics lab. This is where they build the robots to help them with their high energy experiments. This is a mock up of the beamline, and this is used to test out their robots. The beam line is where they fire high energy particles at each other underground. And this isn't a safe environment for humans because of radiation. So instead we can send in robots, which we can control remotely, which was what I was doing here. This robot's got wheels, which lets it move in every direction, even sideways, like a crab. So these can be controlled with a keyboard or with a gamepad, or even through this augmented reality display. This robot has a spinning lidar scanner that builds a 3D model of the room it's in, and it can fit through small holes. And this one runs on a rail and can reach all around the beam line. It's got a radiation detector which monitors radiation levels after the beam is turned off, to see when it's safe for humans to come back into the tunnels.

Microsoft just announced their first qubit which is made out of a novel material called a topological superconductor, or topoconductor for short. This is how it is made, using a superconductor layer on top of a semiconductor. If you want to find out more check out Microsoft's blog: https://azure.microsoft.com/en-us/blog/quantum/

Microsoft's just unveiled a qubit that uses a topological superconductor material, this is why this material is exciting for quantum computer development, it's resitance to noise. Read more on their blog here: https://azure.microsoft.com/en-us/blog/quantum/

Microsoft have just announced their first topological qubit for their future quantum computers. They use a brand new material to science known as a topological superconductor which gives the qubits some robust proteciton against noise Find out more on Microsoft's blog: https://azure.microsoft.com/en-us/blog/quantum/

This is what Google's new development means for the fueld of quantum computing. Google recently unveiled a new quantum computer called willow, and with it they’ve achieved some cool results. Basically here are all the steps you need to accomplish to build a useful quantum computer, this is a useful quantum computer here, we’re not there yet, google just made the step from here to here. That’s a really cool step because it means that they can now do this thing called error correction. The building blocks of quantum computers are qubits, but these qubits drift away from doing what they should do; it's an unavoidable property of quantum systems called decoherence. So to make a useful quantum computer you have to keep nudging the qubits back into coherence, that’s called error correction, and it’s really hard to do. So this is a really cool achievement, and it means they can start working on the next steps. But I should be clear, this quantum computer is not breaking encryption or solving any useful real world problems yet, to do anything useful you need to get to the end of these steps and each of these stepping stones is a huge engineering challenge.
