Kære venner
Det er snart jul og så skal man hygge med lego og grublerier i matematiktimerne. I hvert fald i mine klasser 🥰
I min guldkasse har jeg derfor legoklodser med tal på til et kalenderlys, som vi bruger til gode matematiksnakke hele december.
Måske I kan bruge ideerne, så er det bare at gå i gang 🌟✨

In San Francisco, a luxury skyscraper is slowly sinking and tilting yet people still live inside it. Engineers are racing to keep Millennium Tower safe, but the sight of a billion-dollar building sliding into the ground is nothing short of surreal. And that’s just one story. In this video, we explore other places where architecture and nature clash: artificial islands in Dubai that may sink back into the sea, New York literally collapsing under its own weight, a floating airport in Japan sliding into the ocean, ancient structures hiding secrets underground, and even futuristic underwater cities already being planned. From lost megastructures to vanishing metropolises, these are the world’s most unbelievable building mysteries.

Astronomers have just spotted something the universe has never shown us before — a triple black hole smash-up. Imagine three cosmic giants, each powerful enough to swallow stars, colliding in a single, mind-bending event. In this video, we’ll break down how scientists detected it, what happens when black holes merge, and why this discovery could rewrite what we know about the universe. Stick around — this is space at its wildest, and it’s happening right now.

A simple and clear explanation of all the important features of quantum physics that you need to know. Check out this video's sponsor https://brilliant.org/dos
I have spent a lot of time thinking about how best to explain quantum physics and this is the result of all my hours of pondering, and I’m really happy with how it turned out. I decided to just explain it as it actually is, rather than rely on analogies. The video explains the quantum wavefunction, particle-wave duality, the measurement problem, the double-slit experiment, superposition, entanglement, quantum tunnelling, the Heisenberg uncertainty principle, and energy quantisation. Let me know if it was helpful! Cheers Dx

Everyone is talking about the black hole image, which is amazing! But I've been wondering where actually is the black hole? So here it is. It is inbetween the virgo and leo constellations. Although you can't see it (unless you have a planet sized radio telescope array), it is still nice to know where it is.

What do cosmologists mean when they say Big Bang? Perhaps not what we think. The Big Bang poster is available here: https://store.dftba.com/produc....ts/the-big-bang-post
There are many descriptions of the big bang out there that are wrong. Anything that says the universe exploded from an infinitely small, dense and hot point, known as a big bang singularity, are out of date, but I’ve seen this description in many places on the internet and diagrams. I’ve even been guilty of saying this too! But I’ve recently updated my understanding, so here is what cosmologists actually mean when they say big bang.
Special thanks to Katie Mack for some cosmology help: https://twitter.com/AstroKatie

I sometimes read things about quantum computing that are not quite right, I clear some up here. Check out this video's sponsor https://brilliant.org/dos
Quantum computing is a hot topic these days, but I sometimes see things in the media that I know are probably going to be misinterpreted by the people reading them. So this is my attempt to clear up some of the main misconceptions I see about quantum computing.
But if you are wondering what the state of quantum computing is right now. It is real and exists. The quantum computers of today have a few tens of qubits: as of making this video the highest number of qubits in the universal quantum computing scheme is 72 from Google, and in the quantum annealing scheme is about 2000 from D-Wave. But they work and solve real world problems. They haven’t quite exceeded classical computers, but they are very close, and there are going to be some interesting developments over the next year.

I explain why it is called a square root, and also how a square root works.
#mathematics #DoS
Clarifications:
To keep this video simple I decided to not talk about complex numbers. But perhaps I should have mentioned complex numbers when talking about the square root of negative numbers.
When I said "you can never have a square root of a negative number", I guess I could have said "you can never have a square root of a negative number, unless you use complex numbers."
Cool, well I'm still learning! And thanks for keeping me in check. :D

Find out what it takes for a quantum computer to beat a classical computer to achieve quantum supremacy. Check out this video's sponsor https://brilliant.org/dos
Quantum supremacy’s that moment when a quantum computer beats the best supercomputers at solving some kind of problem, and it’s a very exciting time right now in quantum computing because, as of recording this video we’re on the brink of having quantum supremacy. In this video I quickly describe how quantum computing works, what quantum computers exist in the world today and what you need to do to prove quantum supremacy.
When I posted this video quantum supremacy hadn’t been reached, but people are predicting that it will happen soon.
Also the qubit numbers I posted for the different quantum computing efforts will go out of date quite quickly, so they won’t be valid if you are watching this in the future. Hello from April 2018!
And full disclosure - I used to work at D-Wave but I don’t have any favourites, I’m excited by progress on all fronts and believe they all deserve the same critical analysis.

Not only is this the first time a commercial company is sending people into space, it is also the first crewed mission to the International Space Station to be launched from American soil in 9 years since the Space Shuttle was decommissioned. On the 27th of May SpaceX will make spaceflight history by being the first commercial company to transport humans to the ISS on a Falcon9 rocket in the SpaceX Dragon Crew spacecraft. This is the beginning of commercial spaceflight and potentially the beginning of space tourism.

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

The Map of Superconductivity poster is available here: https://store.dftba.com/collec....tions/domain-of-scie
Superconductivity is a fascinating property exhibited by many materials when they are cooled down to cryogenic temperatures to below a certain transition temperature. Below this temperature they lose all of their electrical resistance and they are able to conduct electricity with zero loss of energy. They also exhibit interesting magnetic effects including the total expulsion of magnetic fields from their interior due to superconducting eddy currents.
In this video I look at the different kinds of superconductors like type-I and type-II superconductors, and high temperature superconductivity, the theory behind them: Ginzberg-Lanadu theory and BCS theory,, and the applications of them in the real world which include superconducting magnets for MRI machines and particle accelerators, quantum devices like josephson junctions and S.Q.U.I.Ds for uses like quantum computing.

Errata and notes:
1. I got the Oxidising Agent and the Reducing Agent the wrong way around! Sodium is the Reducing agent and Chlorine is the Oxidising agent. My confusion was that when a sodium atom looses an electron it becomes oxidised, so in my simple brain, I called it the oxidising agent. That is wrong because the agent that oxidises the sodium is the chlorine atom and so the labels are the wrong way around. Doh!
2. I drew the hydrogen H2 molecule with a double bond but it should be a single bond because they are bonded with a single covalent bond.
3. Where I have drawn carbon dioxide, the carbon should have a double bond to each of the oxygens.
4. Apparently Feynman diagrams are not that useful for theoretical chemistry, so perhaps that wasn't the best choice for the illustration. The feedback in the comments from a real theoretical chemist is "All we deal with is shuffling around electrons, but many many many electrons, so a Feynman diagram would need to be huge but at the same time would be very very repetitive."
5. In analytical chemistry, I should have called it distillation rather than precipitation.
6. My definition of organic chemistry being about ‘life’ is not very good. I should have said that organic chemistry looks at compounds that contain carbon. But there are some compounds in inorganic chemistry that also contain carbon, like carbon dioxide so I guess I'd also have to state that inorganic chemistry is almost everything else.
7. I said that fuels are inorganic chemistry which is misleading when I drew a car next to it. My understanding is that there are inorganic fuels that don't contain carbon, but obviously all the fuels we are familiar with are organic. I thought a picture of a car would tie a few things together elegantly, but it ended up giving the wrong impression. That’s okay, I’m still learning! :D
8. In inorganic chemistry, I should have stated that all natural minerals fall under inorganic chemistry so as not to be misleading, otherwise you might go way thinking that only man-made substances fall under inorganic chemistry which is not true. I said that 'a lot of the inorganic compounds that are studied are man-made' meaning that the cutting edge of research is mostly man-made substances.
9. Apparently water is not the most inflammable substance. I thought it was so that is interesting.
10. In the bonding section, hydrogen bonding and van der waals forces are technically inter molecular forces.

Quantum simulation is a really promising route to discover new technologies of the future by finding new materials with new physical properties. Check out the Qiskit YouTube channel here: https://www.youtube.com/qiskit and this is a good playlist to start with https://bit.ly/2KxqOIV
I’ve talked before about how quantum simulation is my favourite application of quantum computing, so I thought I’d make a video to explain why. And in this video, I run an actual quantum simulation on a real world quantum computer.
You can implement this specific simulation too with this video: https://youtu.be/Z-A6G0WVI9w

This is the Map of Quantum Physics and quantum mechanics covering everything you need to know about this field in one image. Check out this video's sponsor https://brilliant.org/dos
And grab this poster here: https://store.dftba.com/collec....tions/domain-of-scie
I’ve been fascinated with quantum physics and quantum mechanics for a very long time and I wanted to share the subject with you so I made this map of quantum physics to lay out the ideas within the subject, to set some bounds on it so you know its not endless and to introduce you to lots of concepts that if you are interested in them you can dig deeper. When you are approaching a subject like this that’s so complicated it can be quite challenging because you don’t know where to start and you don’t know how all the concepts relate to each other so hopefully this will put everything in context.
This playlist expands on this video with lots of other more specific videos that dive deeper: https://www.youtube.com/playli....st?list=PLOYRlicwLG3

This is my journey to find all of the fundamental constants of nature which took some surprising turns. Check out Brilliant who sponsored part of this video: https://brilliant.org/dos
When you learn physics, you very quickly encounter the physical constants of nature, things like the gravitational constant, the speed of light in a vacuum, planck's constant, the elementary charge things like that. These are numbers which we believe are the same everywhere in the universe, for all time. They are baked into our laws of physics and are very special, because if they were even a few percent different, then the Universe wouldn’t exist and neither would we. They are also fundamental because we can’t derive them from any underlying theory, we just have to take them as being true.
So I wanted to go on a quest to find all of the fundamental physical constants and collect them all together so you can see them all in one place, because that’s the kind of thing I do on this channel. So this video is the story of me doing that. But it took some fascinating twists and turns along the way, and the final set was definitely not what I was expecting, because it doesn’t actually include the ones we are familiar with, the ones I just mentioned: speed of light, gravitational constant, planck’s constant. Watch to find out why.

How many fundamental constants are there? By John Baez
https://math.ucr.edu/home/baez/constants.html
Note that his final set is a little different to mine which is explained in his article. I chose my set to be the easiest to understand.
Here are the actual numbers for all these dimensionless constants from David Black

Music, art, and everything else by Dominic Walliman
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.
Everything you need to know about viruses in a quick visual explanation. You can get the infographic image here https://flic.kr/p/2j2LDWs
At the beginning of this pandemic like everyone I was hearing lots about viruses, but realised I didn’t know that much about what they are. So I did a load of research and have summarised what I learned in these nine images. This video explains the key aspects of viruses: how big they are, how they infect and enter and exit cells, how viruses are classified, how they replicate, and subjects involving viral infections like how they spread from person to person, how our immune system detects and destroys them and how vaccines and anit-viral drugs work.
Human error:
In slide 9 toxin vaccines are for bacterial infections like tetanus, not viruses.

Physics comes up in movies a lot, and as quite a difficult subject it is fun to see how physics is interpreted through the lens of cinema. Sometimes they get it very right and sometimes they get it very wrong!
A friend of mine who is really into movies picked out a bunch of clips for me to interrogate. Some movies I had seen before, and others I hadn't. See how Hollywood does with some hardcore physics!
