I noticed a few years ago that on Facebook I was doing complicated calculations like: Do I actually like this post? Yes/No Do I want the person to know I like their post? Yes/No Do I want other people to know I like this person's post? Yes/No Do I want to see more from this person? Do I want Facebook to know that I like this? etc. so what looks like a simple gesture actually involves complex calculations.
The thing that really drives me nuts, as you saw in this rant of a video is thinking about the reasons people post to social media. Of course we're drawn to the dopamine spikes we get when our posts get likes and comments, this leads us to post more and more engaging content. This is just what the platforms want us to do but I argue it's disadvantageous to our social lives and to our lives period. If you always have that process running in the background searching out the perfect photo or the right moment, how do you ever live in the moment?

That is an affiliate link so by ordering through the link, LifePixel will give a commission back to me. If you don't want that, just use a different link.
I've always been fascinated to film in the UV because it reveals to us a world that is always there but invisible to us. Most objects are not surprising but skin, dish detergent, flowers, tonic water, and optical filters are all very different in the UV part of the spectrum.
The UV-pass filter I used was the Baader-U. The other filter was the ZWB1 that you'd have to use in conjunction with an infrared blocker. I have one around here somewhere but not sure exactly where.How Earth Creates Its Magnetic Field2veritasium2018-07-14 | How turbulent convection currents in Earth's outer core make its magnetic field This video is a prequel to one that will appear here: http://ve42.co/Spin
Huge thank you to Prof. Jon Aurnou who spent a lot of time explaining how planetary magnetic fields are created. He changed a lot of my preconceptions. His youtube channel is here: youtube.com/user/spinlabucla His research page is here: http://ve42.co/SpinLab
OK, so what were my preconceptions?
1. That the Earth's magnetic field is a passive thing - it shouldn't need a continuous input of energy to maintain itself (that seemed reasonable to me because the magnetic field has been around for a long time and it seems mostly stable). But as it turns out, the Earth is a giant electromagnet, and so of course those currents dissipate their energy as they encounter resistance in the liquid metal through which they flow. So the energy to continuously create these currents comes from the kinetic energy of the liquid metal flows in the Earth's outer core.
2. If it's convection, I'm thinking hot things rising, cooler things falling. But apparently the main effect driving convection is the compositional differences at the boundary with the Earth's inner core. This is because of the differential freezing at the boundary. Things like iron freeze into the inner core, while elements like sulfur do not. Hence the pockets of lighter material which then rise outwards.
3. I didn't get why the fluid motion was necessary for the generation of the magnetic field. I mean if it's a conducting liquid, it can conduct currents whether it moves or not. But the key is that the liquid metal can 'trap' magnetic fields. I imagine this like how iron channels magnetic fields. Then once these fields are channeled, they can be pulled and stretched, making more magnetic field.
4. Fluids operate very differently in rotating frames of reference. This is something I didn't intuitively grasp. But, as fluids move from the inner core outwards, those particles are moving much more slowly in the direction of rotation than the matter that has been there for a long time, which means the convection currents get deflected and form helices.
Listening to Prof. Arnou's explanation made possible my explanation in the other video (it's really just a summary of what he says here). So thanks Prof. Arnou!The Climbing Magnets Mystery (ft. Steve Mould)2veritasium2018-04-06 | When spun on a screwdriver, magnets climb up its length, but why? This video brought to you by my friend Steve Mould: http://ve42.co/SteveMould
This all started with a question on twitter, when someone wanted to know why a chain of neodymium magnets climbs up a screwdriver when the screwdriver is rotated. A search for the explanation ensued, culminating in the stick-slip conclusion presented in this video. Let us know what you think in the comments.A Misconception About Science2veritasium2018-03-20 | Based on The Structure of Scientific Revolutions by Thomas Kuhn Check out our new series! Paradigms: http://vrv.co/paradigmsWill Robots Take Our Jobs?2veritasium2017-09-22 | In short, yes they will, continuing the trend of humans working less. This video was sponsored by "Robot-Proof" written by Northeastern University's President, Joseph E. Aoun. Learn more here: goo.gl/hqBDLA
When I think about robots taking our jobs, I am neither of the opinion that we need to panic amidst the imminent robopocalypse, nor am I confident there will always be work for everyone. Instead I think we will see something similar to previous revolutions (e.g. agricultural and industrial). That is, ultimately everyone will be better off, working fewer hours and doing tasks more suited to people than to machines (thanks to widespread automation), but during the transition there will be discomfort. This discomfort arises when people who have been working particular jobs for most of their lives find themselves out of work, or find their jobs don't even exist anymore. Then education and retraining is the challenge, something that's not easily accomplished and something our educational system is not setup to do.Why YouTube Used to Prefer Quality2veritasium2017-06-29 | Almost four years ago I made a video about quality vs quantity on YouTube. Reflecting on how the platform is working in 2017 I find that quantity (frequency) has become significantly more important and quality less so.
I'm not saying this is my recommendation for how people should make channels, just that this is what seems to be an effective strategy nowadays.
This video involves two distinct sections: on the streets of London and in "studio". The London stuff was filmed to correct mistakes in the earlier studio shoot.
The studio shoot was filmed by Raquel Nuno. London street stuff was shot by me on a Zhiyun Crane with GH5.5 Bad Reasons to Ditch the Paris Climate Agreement2veritasium2017-06-02 | I've heard a lot of reasons for withdrawing from the Paris climate agreement but none of them makes sense to me.
Did you notice that Gunn and Drew were named that way so they rhyme with one and two, helping reduce any sort of confusion you might have in associating each character with the right system.
Thinking Fast and Slow by Daniel Kahneman is one of my favourite books (in case you hadn't guessed). I think the findings he summarizes in it really resonated with me and collected a lot of strands (or chunks) of my thinking.
One of the main findings I think we forget is that working memory is limited. This needs to be taken into account in every educational discussion. We can't simply talk philosophically about the purposes of education. We must also discuss the brain's response to different teaching methods, because ultimately that's what we are trying to affect.
To me the psychology of system one and two suggests we need to be careful to give students challenges that are within their 'zone of proximal development' i.e. capable for Drew to Grasp because Gunn has already automated a lot of tasks relevant to this challenge.Why Create a Third Channel?2veritasium2017-02-18 | Answering questions about why I made a third channel: http://bit.ly/Sciencium Help me make Sciencium: http://bit.ly/ScJoinUs Suggest topics: http://bit.ly/VeIdeas

Now it's gotten to a point where there is so much 'free time' that demand for distraction supports 24 hour news sites and YouTube channels. I'm proposing that following our impulses into constant distraction may not be the best way to spend our time. It may prey on weak points of our psychology that evolved hundreds of thousands of years ago and it may make us think less effectively. Now consider I'm making this argument in a YouTube video you may be using to waste your time.

Share this on Facebook ;) Facebook is a complex ecosystem of individuals, creators, brands and advertisers, but I don't think it serves any of these groups particularly well because its top priority is to make money. Now, I don't think making money is a bad thing, in fact I hope to make some myself. The problem is the only way Facebook has found to make money is by treating all entities on the site as advertisers and charging them to share their content.
This business plan backfires because 1) not all entities ARE advertisers and 2) it was the content from these people, specifically friends, family, and creators that made the site worth visiting in the first place. Now the incentives are misaligned: - individuals want to see great content, but they are now seeing more paid content and organically shared content which appeals to the lowest common denominator (babies, weddings, and banal memes) - creators want to reach fans but their posts are being throttled to force them to pay to be seen - brands and advertisers have to pay once to advertise their page on Facebook, and then pay again to reach the people who have already liked their page. Plus Facebook is not a place where people generally go to buy things.
Facebook stands in contrast to other social media like Twitter, YouTube, and Instagram where all content is shared with all followers.The Magic of Science2veritasium2013-12-27 | Post what seemed like magic to you in the comments.

One of the reasonable tasting and non-toxic insects in Australia is the green weaver ant, or oecophylla smaragdina. It contains ascorbic acid (vitamin C) and so it tastes sour and refreshing, at least the Aborigines thought so - they used green ants to flavor water and for some medicinal purposes. It would take a lot of ants, though, to make up a single day's calorie requirement - something like 75,000 ants.

In this video Associate Professor Andrea Morello from the University of New South Wales explains how 'zero-point motion' makes it possible to use Helium-3 and Helium-4 in a dilution fridge to get down to only thousandths of degrees above absolute zero. It is this technique which is used to cool the MiniGrail at Leiden so that it can act as a gravitational wave antenna.
