Is life really that complex? | Hannah Fry | TEDxUCL
Hannah Fry trained as a mathematician, and completed her PhD in fluid dynamics in early 2011. After a brief period working as an aerodynamicist in the motorsport industry, she came back to UCL to work on a major interdisciplinary project in complexity science. The project spans several departments, including Mathematics and the Centre for Advanced Spatial Analysis, and focuses on understanding global social systems -- such as Trade, Migration and Security. Hannah's research interests revolve around creating new mathematical techniques to study these systems, with recent work including studies of the London Riots and Consumer Behaviour.
Talk: Is life really that complex?
Recently scientists have begun to appreciate that many of the mechanisms inherent in our social systems have analogies in seemingly unrelated problems. The movement of a crowd, for instance, can be understood using techniques traditionally applied to the flow of a fluid, and the uptake of a new technology can be predicted using knowledge of how disease spreads.
By exploiting these analogies, a new field is emerging at the interface between social sciences and mathematics, the potential of which I hope to illustrate using a mathematical model of the London Riots. Our approach can demonstrate why certain areas of the city were at higher risk than others and help determine which policing strategies may have resulted in a swifter resolution to the unrest.
We will discuss how social modelling can provide a greater understanding of our society, and help design better systems for all: from healthcare to policing and policy.

Hannah Fry's passion for math is contagious, and she really has a gift for explaining complex concepts with clarity.
I love Hannah Fry and how she can distill complicated topics and present them in an accessible and interesting way to pretty much any audience. She is a truly remarkable woman.

And she's absolutely right about that
Hannah has grown so much in her talks. She seems nervous in this one, but if you watch her other talks, you see how confident and calm she is. It’s wonderful.
Hannah's posh is perfectly authoritative to these social issues and as soon as you finnish all or her vids about the rioting mechanisms in urban contexts are incredible puzzles for behavior solutions with a solid human rights vs security balanced approach
The beauty of science :-) Thx Hannah!
I definitely trained my brain to work like this and it has been very helpful in understanding things. I wish more people would do the same.
I just fell in love with Math.

Her goal is to define the real complexity of human life, of all aspects of it, in the simplest form possible. Likewise, she's trying to explain that just because it is complex does not mean it is impossible to understand. She's giving you a range of information that all apply to the same base subject. People underestimate how truly complex life is, and how broad the subject of "life" can really be. She's just wrapping it up for us who would otherwise never think about it.
Ah yes, of course. We must all employ guard leopards to deter burglars. Thank you mathematics.
Great video. Interesting approach. Thx!
Best first 20s on TED I've seen so far. +1 for 3:25. +10 for the accent.
Law of large numbers seems to be the key here. Randomness is a highly structured phenomenon as it will always play out the probabilities. This is some fascinating research!
I m flattered. thk u.
these analogies are really interesting!

Brilliant arguments by analogy!
there are logics (or semiotics if you will) setting the rules for how any living system will interact with externality at every location where such interaction occurs. we lack a theoretical framework, let alone anything that can be applied for most of them with obvious incomplete exceptions including genetics and linguistics

I don't think i'd ever get tired of hearing her talk...
Was expecting a video on biology, but this was good too.
very very good, opened my eyes
Great talk on ted as usual :)
As a female scientist myself it saddens me how many of the comments are about her looks and how few are about the topic. Even those that mention her intelligence - that''s not the reason she was on that stage. And if it was me, I know I would learn to hate compliments on my looks when they are taking away from what I'm talking about. And yes, I do realize the irony that this is now one of those comments about her looks.

It all comes down to scale. Anything can be extremely simple OR extremely complex at the same time. It depends on how detailed of a perspective you decide to observe something from.
Amazing talk
Amaaaazing !!!!!!!
A generalized understanding of complexity would be so profound in its effect upon humanity that I don't believe we can even begin to guess at it. It would be like asking someone a few decades before the birth of Euler what they thought the impact of widespread availability of computers would be. Things which we would think are impossible or would assume must be magical would become commonplace.

After watching this I'm left with the question "So, overall, what are you saying?!", and "Why did I spend 10 minutes watching this?". I guess I was hoping that it'd start to make sense at some point just because it's a TED talk! Lesson learned.
Great speech
This was way to short. She is so good and interesting it seems she barely got started and she was done. I hope she does more Teds on the subject, but I think any she would wow on what ever idea she spoke of.
I love her voice :-)
This is true to an extent, we can also learn a lot from bio-mimicry. It's a great way to visualize, gain insight and ideas but should not be taken in with absolute certainty.

90% of the comments are about Hannah Fry’s titian beauty. Including this one.
Nicely presented in a crisp manner....i have always felt nature has answers hidden in plain sight in simple things even for the most complex of problems..it seems to me that its in the 'design' of evolution where certain patterns develop & get reused or built upon much like software..maths is one sense to perceive this..but there are others..
10:00 "Thank you!" and whoosh, she's gone. :)
Lots of information to convey in a very short amount of time. Bravo, as usual. Top tip: subscribers, search for her less hurried presentations (even the casual Rock-Paper-Scissors one) and be prepared for cognative stimulation and to fall in love. You're welcome ;)
point is, some things are easy to model and some things need a deeper combination of models.
So it's basically like the study of Chaos and Game Theory.

+cryora I think it's more a study of complexity, which lies between chaos and order. For instance, take the surface of an ice cube in warm water. In the water there's chaos on the molecular scale. In the ice, there's the order of a crystal. In between, with both water and ice, there's complexity. The three regions are distinct from one another.

memyself oh ok, I've never really heard of complexity. I've taken a dynamical systems course since I've watched this vid so I know a bit more about chaos. But all I know about complexity is that it's complicated or complex numbers.

+cryora I'm not very current on dynamical systems, but I think Chaos has achieved the status of a science. Complexity, however, is not yet firmly established as a separate discipline, despite the considerable efforts by the Santa Fe group, which had some pretty bright people exploring the idea. I think these efforts were made in the 1980's and 90's, and it looks like progress has been made since then. You can find much explanation by searching for "complex systems." I don't know how seriously we are to take the word "complex" in the title of this video. Perhaps I was reading too much into it and the word is not to be taken in a rigorous way. It would've been nice if Hannah explained something about all this.
brilliant
Hari Seldon's psychohistory beginnings! :)
I wish i knew about this while I was in undergrad >.>
Pretty and brilliant ...
Perhaps this is how intuition works. We see strange new things and immediately have a sense of how said strange, new thing might work. It's like pattern seeking maybe. Also, she's so pretty. *-*
This is what I want to make my area of expertise of. Because everything that is happening can be found happening somewhere else, which coincides with my theory of everything and feeds into my nihilism. I always did like redheads, but in the end, what choice do i have.
I totally agree with U ;)
I don't know where your problem is people. The topic is absolutely interesting, she does a very good presentation and it actually is about scientific facts, not just some emotional bullshit like it sometimes happens at Ted.
This is a fantastic speech (and not just because the speaker is attractive).
Life is as complicated as each one of us wants it to be!
She talks so fast that my heart began to race just listening...
A slide of Dave Lister holding a 4 pack of lager would've got a free laugh out of a British audience.
We all think that we make rational decisions and make rational choices. The truth is that the most decisions we make doesn't even enter our conscious awareness. And when we do choose consciously, the result of our choice depends on what experience we had. But where does an experience come from?It comes from environment. "deterministic machines" just feels worse comparing to "free minds that have the whole world open for them" I'm aware enough to know that I'm a dependent part of a larger system.

What if reality is a multiverse that follows the rules of Pascal's triangle, which is both random (in a pure mathematical sense) AND deterministic?
The description of the Riot Epidemic is getting close to Dawkins' Meme Theory
fair enough- statistics and patterns help, but it's not so simple to just 'apply what we know'. Models can be introduced, but their accuracy will depend on the people applying, analysing and learning from mistakes and that would take decades for every single issue she describes! Good idea, though, someone give her a medal :)
that's exactly my point, you can't predict (with accuracy) human behavior, you might get lucky once in a while but that's about it
@juanausensi499

The point of the video is that you don't need to predict the behavior of every individual to be able to predict the behavior of large groups of individuals. Think of the example of weather/individual mollecules in air
Also there's a difference between knowing something and understanding it. Common sense told us that objects will fall to the ground when dropped. Yet truly understanding it on a mathematical level is how we were able to get to the moon and a million more things. I suppose that could all be considered a waste of time and energy though.
Agree 100% and it is not complex, however, the flaw is the human beings who fails to execute accordingly.
My ideal woman - beautiful, redhead, maths expert, Monopoly fan! Etc.
The modelling of rioting might be interesting if we want to observe how riots break out and eventually die off. However I think if the authorities start using it as a tool to better manage or contain such events, it might lose its effectiveness. It is possible that once we start to tinker with the variables (where police should be deployed), the model will fail, much like many economic policies
We are getting closer. Someday Hari Seldon will be among us.
Hannah Fry is Queen, shame about UCL not Imperial haha!
The question remains then: who would you trust to do the taking and redistributing of resources? How would you know who to trust with a task of such extreme magnitude? Would rich people then also be motivated to buy favors from those who are entrusted to take resources? What stops those who are in the job of taking resources from siphoning off those resources for themselves and their friends?
As always, there's a corollary question : whose hands will it be in ? If these tools were available for dictators, well…

So what should I do, stop buying products? I don't feel used or manipulated.
She seems to be connecting things that don't necessarily follow. Humans, especially the bright ones, sometime seek patterns to a fault. Some of the similarities mentioned were, at best, vague.
Interesting top-down approach, though looks to me that the bottom-up would be more sustainable.
Never high enough!
If we can predict human behavior in aggregate, how is that we can't predict the next stock market crash?

Life is as fair as u create it! World is big and it always evolve. You saying JUST TAKE IT... doesnt do anything. Then go, take it! Oh you cant? Ofcourse not, not now, cause if u could you already changed the world. World is never right or wrong, good or bad, its always situation, an act, and just how we(individuals - YOU, ME) manage to deal with that act at that moment, knowing what is the rightest thing to do from your own perspective - that makes difference. The world is how YOU create IT :)
Three thoughts: 1. It is interesting how useful analogies are to give us a more dispassionate perspective on those things we have the hardest time viewing objectively (i.e. our own behavior and human behavior in general). 2. Just scrolling through a few pages of these comments it seems like roughly half comment on her sexual attractiveness and the other half seek to belittle either her intelligence or her motives. 3. I find comment sections on web sites increasingly pointless, even harmful.
