Strangely enough, the answer seems to be yes. Check out the sponsor of this video Brilliant: brilliant.org/DOS Neutrinos are the least well understood fundamental particle, and the fact that they don’t interact very much doesn’t help us study them. 300 trillion go through your body every second which is why some people call them ‘ghost particles’. But very occasionally they do hit us, and I wondered what would happen if one of them happened to hit us in our eye. Could we see it? So I figured it out with the same physics behind neutrino detectors, and the answer seems to be yes! Although you need a lot of eyes.

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.

The standard model of particle physics is our fundamental description of the stuff in the universe. It doesn’t answer why anything exists, but does describe what exists and how it behaves, and that’s what we’ll be discovering in this video. We will cover the fermions, which contain the quarks and the leptons, as well as the bosons or force carriers. As well as which of the fundamental forces each of these fundamental particles interact with, along with the Higgs field. We’ll also look at the conservation rules of particle physics, symmetries in physics and the various quantum numbers that rule which particle interactions are valid and which are not.

But what actually is it, and is it even real? Support this channel: patreon.com/domainofscience and store.dftba.com/collections/domain-of-science
Here I explain what they are and show a visualization of what they look like, and show how they are similar to many other waves we are familiar with. Overall the wavefunction is a mathematical tool which keeps track of all of the properties of a quantum particle, and explains our observations of the probabilistic nature of where particles appear when we do experiments on them. From the wavefunction we can calculate all of the observables like position, momentum, energy or spin, by applying mathematical operators on it. So in quantum physics, the wavefunction encodes all of the information about the quantum system, and valid wavefunctions are solutions to the Schrodinger equation which I covered in my last video which you can watch here youtu.be/AR23uxZruhE

(reupload for #shorts)Domain of Science2021-02-20 | The Schrödinger Equation is the key equation in quantum physics that explains how particles in quantum physics behave. You wanna know where your electron is going to go? That’s the Schrödinger equation you’ll need.
So why does it look so complicated? Well it’s because in quantum physics, when you are describing what a thing like an electron will do, it doesn’t follow the rules of particles it follows the rules of waves, and that’s what these psi’s are, they are wave functions.
Okay so an electron is a wave, and a wave can evolve in space and in time, but it can’t evolve in any old way, there are constraints about how it can evolve, and those constraints? That’s what the Schrödinger equation is telling us.
It says that over time the total energy has to stay the same. And this total energy is made of the kinetic energy, and potential energy. An example of a potential energy for an electron is just being in an atom.
So if you want to see what a quantum object will do in the future, you need to find the wave function that will satisfy all these bits of the Schrödinger equation.

But in the midst of all the doom I started to wonder, what other things could threaten humanity, that we are not thinking about? So I made the Map of Doom to list all the threats to humanity in one place.
But just finding them all is not enough. I wanted to find a way of comparing the risks of all of these disaster scenarios. So this video follows my attempt at doing that, and I think I’ve hit on a great way to visually compare all these dangers, which I haven’t seen anyone do before, so hopefully by the end of the video you’ll have a better idea about what the biggest threats are, and how they compare to this pandemic.

But THIS is.Domain of Science2020-10-30 | 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: 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.

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 https://math.ucr.edu/home/baez/constants_table.pdf

Aliens will most likely leave a tell tale trace of their life in the atmosphere’s of their planet. But how do we know what chemicals the atmosphere of a distant planet contains? The answer is atomic spectroscopy. If we see a planet passing in front of it’s star, some of that starlight is absorbed in a very specific pattern called an atomic absorption spectrum. Each element has a specific pattern like a barcode, so through careful analysis of the light it can tell us which gasses are in the atmosphere and their proportions. We already use this technique for other space objects like stars and nebulae, measuring properties like temperature, density, ionization and relative velocity. This is a gift that nature and quantum physics has given us and the majority of what we know about the universe is based on this technique.

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.

Sherlock Holmes image by Sidney PagetQuantum Gravity Explained in 9 SlidesDomain of Science2020-07-02 | Why don’t we have a theory of quantum gravity yet? I explore why it has been so difficult. Check out this video's sponsor brilliant.org/dos Our best theories of physics are incomplete, quantum mechanics and general relativity don’t work when we try and put them together so physicists have been looking for a grand unifying theory of quantum gravity for decades, and so far have failed. This is because it is virtually impossible to make an experiment where the large and small scales meet, so we look to the places in our universe where this happens naturally: black holes and the big bang via the cosmic microwave background. In this video I explain what our best theories are and how we are trying to get to a theory of quantum gravity.

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.

This was the first example that really opened my eyes to the real value of calculus. I learned it in university in my physics department mathematics class, and it was just the beginning of a long journey of me wielding calculus at all sorts of practical problems in physics, and it gave me the power to see where the equations of physics came from, rather than just having to learn an memorize them.

Ninety seven percent of the galaxies in the observable universe are moving away from us faster than the speed of light. You might wonder how this can be true when one of the unbreakable laws of the universe is that nothing can travel faster than light. But this only applies to things moving through space and these distant galaxies are getting further away from us because the space between us is expanding. So the distance between us and them is increasing faster than light could travel across that space. This is also why the observable Universe is 45 billion light years across despite only being 13.8 billion years old. #space #cosmology #DomainOfScience

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.
Human Errors: 1. I got the time that matter and antimatter annihilation happened. I should have said it happened within the first second instead of the first few minutes.

This video explores all of the things in the Universe from our Earth and local Solar System, out to the Milky Way Galaxy and looks at all of the different kinds of stars from Brown Dwarfs to Red Supergiant Stars. Then to the things they explode into like white dwarfs, neutron stars and black holes. Then we look at all the other kinds of galaxy in the universe, blazars, quasars and out to the cosmic microwave background and the big bang. It covers most of the different things that we know about in the Universe.
The European Space Agency Mission LISA (Laser Interferometer Space Antennae) will launch in 2034 and will revolutionize the way we do astronomy. With a 2.5 million kilometre arm length it will be able to see kinds of gravitational waves that are impossible to see using Earth based detectors. Cool things it will see are collisions of super-massive black holes, orbiting white dwarf stars and measurements that will calibrate distance measures like sephid variable stars and supernovae, and it will be a new independent way of measuring the Hubble constant.

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.

Here is a brief description of calculus, integration and differentiation and one example of where it is useful: deriving new physics. In this video I start with a very simple derivation which shows the relationship between momentum and kinetic energy, and then show a simple introduction to integration and differentiation.
When I learned physics at University one of the most satisfying experiences was getting to grips with calculus enough to use it to derive equations as it allowed me to wield mathematics to describe the world, which felt awesome.

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.

Lots of people find mathematical equations intimidating because they don't make sense. But they are not hard to understand if you follow a few steps, anyone can learn to read them. And it is well worth it because they are so incredibly useful to describe everything in math and physics. If you already know I'm sure you know someone who might like this video, I'm going to send it to my family who are less mathematically inclined than me.
The steps you need to know are: 1. Find the variables, 2. Work out what all of the different mathematical symbols mean, 3. Wok out what order you would perform the mathematical operations if you were going to plug numbers in to the equations. These steps really help you get your head around what an equation is telling you. Also, don't be scared about the greek letters, they do just the same thing as normal letters, they either represent constants or variables.

Computer science is the subject that studies what computers can do and investigates the best ways you can solve the problems of the world with them. It is a huge field overlapping pure mathematics, engineering and many other scientific disciplines. In this video I summarise as much of the subject as I can and show how the areas are related to each other.
A couple of notes on this video: 1. Some people have commented that I should have included computer security alongside hacking, and I completely agree, that was an oversight on my part. Apologies to all the computer security professionals, and thanks for all the hard work! 2. I also failed to mention interpreters alongside compilers in the complier section. Again, I’m kicking myself because of course this is an important concept for people to hear about. Also the layers of languages being compiled to other languages is overly convoluted, in practice it is more simple than this. I guess I should have picked one simple example. 3. NP-complete problems are possible to solve, they just become very difficult to solve very quickly as they get bigger. When I said NP-complete and then "impossible to solve", I meant that the large NP-complete problems that industry is interested in solving were thought to be practically impossible to solve.

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.
