This is the Map of Black Holes which isn’t a map of where all the black holes are in space, it’s a concept map of the subject of black holes: laying out our current knowledge of them. Their structure including Schwarzschild radius or event horizon, the singularity, photon sphere, innermost stable orbit, accretion disk, Hawking radiation and the difference between rotating and non-rotating black holes. I also look at the evidence for their existence, the many ways we have detected them though x-ray astronomy, gravitational wave astronomy and radio astronomy. Then the many outstanding mysteries still to be solved including wormholes, the holographic theory and information paradox. They are very fascinating objects indeed.

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 https://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.

Arguably the most likely way we will first discover alien life on another planet will be using the power of atomic spectroscopy. You can grab the Map of Quantum Physics here https://store.dftba.com/collec....tions/domain-of-scie

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.

Calculus is an incredibly useful tool for deriving new physics. Check out this video's sponsor https://brilliant.org/dos

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.

Baffled by equations, well no more! Continue learning at this video's sponsor https://brilliant.org/dos

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.

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.

Biology is the subject that studies life in all its forms, from the simple cell through to all the animals that inhabit the planet. In this map I lay out the subject of biology and how all of the sub-disciplines are related to each other: microbiology, genetics, bioengineering, anatomy, physiology, medicine, neuroscience, ecology, zoology to name but a few.

Biology spans the scales, from biophysics and biochemistry studying the basic elements of life, to the study of whole ecosystems and the environment. If there is one word that describes biology, it is complexity. There is a huge amount we still don’t understand about how life works, how it started and how it ended up with us.

An introduction video to the field of Ultra-cold Atom Physics filmed at the MUARC summer school in 2010.

This video introduces the concepts involved in cooling down atoms to such low temperatures that their quantum mechanical properties can be observed and manipulated.

Fundamentally everything is made of particles and these particles are are described by a quantum wavefunction. But what actually is it, and is it even real? Support this channel: https://www.patreon.com/domainofscience and https://store.dftba.com/collec....tions/domain-of-scie

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 https://youtu.be/AR23uxZruhE

Your nose uses quantum tunnelling to smell! This crazy conclusion comes from the latest interpretations of the evidence about how our smell receptors detect odour molecules. This video summarises the two models of smell: shape theory and vibration theory, and concludes that you need both to explain how we smell.

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.

An introduction to the Interpretations of Quantum Mechanics. The first 500 people to sign up via my link will get two FREE months of Skillshare Premium: https://skl.sh/domainofscience
The interpretations of quantum physics are a collection of attempts of many physicists to try and make quantum physics make sense. The measurement problem and entanglement are notions that are confusing to us humans and people puzzle over questions like: Is the wave function real or just mathematics? What does a subatomic particle really look like? What is particle-wave duality really? That is where the interpretations of quantum physics come in. This is my attempt to cover the main ones.

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.

This follows my journey to find and rank all of the biggest threats to humanity. Grab yourself the Map of Doom poster here: https://store.dftba.com/collec....tions/domain-of-scie

Link to Veritasium’s Asteroids video video: https://youtu.be/4Wrc4fHSCpw

This year was the first experience we’ve had of a global disaster affecting every single person on Earth. And also how unprepared society was to deal with it, despite plenty of people giving warnings that this was going to happen at some stage.

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.

I look at the galaxies that are moving away from us faster than light because of expanding space. Check out this video's sponsor https://brilliant.org/dos

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.

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
