The Map of Plastic Waste

In this video I give you 5 things you can do to reduce plastic waste. The #teamseas movement is great, but there is so much more we can do to reduce the estimated 10 million tonnes of plastic and trash dumped into our rivers and oceans every day.

We look at all the top science stories for the year 2019. Here are the links to the original articles https://medium.com/@DominicWal....liman/science-of-201 The mainstream news tends to be a little bit negative, I'm sure you've noticed. And whenever I'm bummed out about the world I turn to science! There were so many amazing science discoveries and advances this year that we can really be proud about. Humans are doing amazing things all over the world and this livestream is a celebration of that!

Beer Made With Wasp Guts!!

You need yeast to make beer. Scientists discovered that wasps have yeast in their bellies, so why no make beer out of it! Brassneck brewery did just that so I went along to try some of their beer and find out why.

I was not sponsored by Brassneck or anyone to do this video, I made it because I find it very interesting!

Solution to the physics puzzle I posed in the last video. Check out the original video here https://youtu.be/cadNZJvfl7s

I asked you if you could work out what proportion of the galaxies in the visible universe are travelling away from us faster than the speed of light. Here is how I did the calculation and reached the 97% number.

What's The Probability You Have Seen A Neutrino?

Teacherflix
0 Vues · 5 journées depuis

Can you see neutrinos with your eyes? Strangely enough, the answer seems to be yes. Check out the sponsor of this video Brilliant: https://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.

Who Has The Best Quantum Computer?

Teacherflix
0 Vues · 5 journées depuis

This is a summary of all the main companies building quantum computers today, and what their most powerful machines are. You can get the digital image here: https://www.flickr.com/photos/....95869671@N08/5184976 But we can’t simply look at qubits counts because so many other factors go into the quality of a quantum computer, so here I look at the quantum volume metric which is a much better way of comparing machines. And we look at what steps these companies need to take to achieve large scale useful general purpose quantum computers, and the timelines the companies have set out to achieve these.

Movie Night With a Physicist | Movie Physics #1

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!

VIRUSES Explained in 9 Slides

Teacherflix
0 Vues · 5 journées depuis

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.

Big shoutout and thanks to these people for fact checking my work:
Dr Michael Bramhall
Dr Christoph von Arx

The Quantum Technology in Your Pocket

You might not know that you use quantum technologies every day pretty much constantly. Here I have summarised five of them, but there are many others. Quantum physics is often seen as a weird part of physics, far removed from our every day lives but this couldn’t be further from the truth. The entire modern world exists because of our understanding of quantum physics!

Find the Volume of Any Shape Using Calculus

Teacherflix
0 Vues · 5 journées depuis

Calculus isn't just abstract mathematics, it is an incredibly useful tool. Here I show you how to use it to derive the volumes of 3D shapes. Check out my posters here https://store.dftba.com/collec....tions/domain-of-scie

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. Awesome!

The field of Engineering is amazingly diverse touching just about everything in our world. In this video I attempt to capture all of that diversity in one picture: the Map of Engineering, so that we can get our heads around it all and set some bounds on the subject. If you are interested in learning about engineering or want to pursue it as a career this video might help you figure out what direction to pursue.

Map of Science (and everything else)

Teacherflix
1 Vues · 5 journées depuis

The Map of Science explores what science really is. Check out this video's sponsor https://brilliant.org/dos
In this video I investigate what makes a science a science, and how the scientific method is used in different subjects. I lay out all of the areas of human endeavor and show how they relate to each other from philosophy, through the sciences, to the social sciences, the arts and back to philosophy which I have drawn as a big donut. The main theme is that the scientific method is harder and harder to apply to subjects as they deal with more and more complex systems.

When I said I did in depth maps of ‘all’ of these subjects, I meant just the main ones, mathematics, physics, chemistry, biology and computer science.

LISA | The Biggest Space Mission Ever

The Lisa mission will be really cool, I look at all the reasons why.

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.

Why is Earth Hotter Further From the Sun?

Teacherflix
0 Vues · 5 journées depuis

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.
