Her voice makes me super uncomfortable, it makes me feel like there is someone standing behind me. She is an awesome mathematician, so I bear threw and watch.
i love the way she explains things and does not hesitate to draw upon multiple sources and analogies when figuring things out. the 2d-3d explanation was so ultimately short an clear. just perfect. :-) and she is gorgeous. somehow she reminds me of that ginger girl in "that 70s show". ;-) p.s.: social network analysis rocks! ;-)
Fleas can actually jump well over 50 times their body length. But yes, that is still easily understood by considering scale. In more extreme cases, consider the pressure bacterial spores can withstand. Although most bacteria would be killed or inactivated at such extreme pressures, a wide variety can withstand 6,000 standard atmospheres. So why don't we make our submarine hulls out of protein? The answer of course is that these material properties don't apply at large scales. I wonder how much pressure a steel particle of 1 μm diameter could withstand!
Insects do breathe by osmosis, but so do we (oxygen osmosing from air into blood vessels across the membranes of our lung cells). The difference, rather, is that insects breathe by diffusion to a much higher degree than we do. That is to say, they rely on the passive movement of oxygen into their thracheae, whereas we actively breathe. Then again, some larger insects (and spiders!) actively ventilate as well. Just look at the pumping abdomen of a wasp or dragonfly, for example. :)
look up ratio on Wikipedia or any other website for that matter. Or ask your maths teacher, or look in your maths exercise book. as an example 1:2 ratio is as 1 of something increases the other increases by 2, not the square of the number. It is essentially a fraction, 1/2, as a function for finding the other number.
I've heard that insects were bigger in certain prior eras when there was more oxygen in the atmosphere, and bugs are as big as they can be while still being able to respirate in our current atmosphere
That's mentioned in the video: Ants breathe through osmosis. They don't have lungs to draw in fresh air and expel "used" air like we do, nor do they have oxygen travel through the circulatory system. Instead, they have spiracles (vents) that lead to tracheal tubes all throughout the body, so that oxygen from the air goes directly into oxygen-starved tissues, and built-up carbon dioxide goes directly from cell to relatively less densely carbonated air. So with a higher concentration of oxygen in the atmosphere, less air can provide the same amount of oxygen, leading to a higher potential number of cells able to be "fed" by this relatively simple system. Which means ants and other insects could be scaled up in size and still breathe safely. en.wikipedia.org/wiki/Respiratory_system_of_insects

The illustrations should've been placed in a layer behind her as it ruins the feeling when the illustrations cover her hands. Also there's apparently a black bar on the right side of the screen that 'cuts' her hand when she extended it that much to the right. Otherwise - great video and incredible pleasant voice to listen to!

Please could you guys do something on arcade machines such as 2p droppers, toy grabbers, slot machines please? Something like probability and such. Thanks
What about rowing??? Everybody says rowers should be big and heavy but judging your explanation they should be short and light because rowing is endurance race (2-6 km depends on the race).
Indeed, an easy example of how weight has an effect is by looking at a cube of say..one kilo, make it 2x2 and you have a cube that is double in size, but is four times the weight, muscles are somewhat the same and they also have to support the body itself.
Is the graph at 2:10 correct? Doesn't look right to me. I would have thought it should level off as size of animal increases. The graph suggests that power increases exponentially with size.
Thanks for replying! Wow that's so cool! I'm trying to do the same thing, but it's really hard! Do you know the details about what kind of screen it is and what software you use?
Someone should tell this to the people in Attack on Titan. If the titans are 3-12 metres tall they should be impossibly easy to beat. (actually the story does mention that they're incredibly light and therefore a 12 meter tall titan only weighs as much as a man in armor)
Like the info and the charismatic presentation, but dislike the undermining of my plans to get bitten by a radioactive spider and become able to lift seven times my own weight.
I get it and the math adds up, but I don't understand how dinosaurs got as big as they did or as to why the we're so strong as they were. Please explain to me. I am confounded, and confused.
Holy shit this woman's voice is so nice to listen to
+Lucas right....I was just drawn in...that voice...
+Lucas math ASMR.
YES!
Her voice makes me super uncomfortable, it makes me feel like there is someone standing behind me. She is an awesome mathematician, so I bear threw and watch.
Hanna Fry! A real mathematician too!
Hannah is sooo comforting to listen to. Wish i had me one.
Is it just me or is her voice so soothing
I find her voice obscenely sexy.
i could listen to her all day
That title though
Omg you just made me burst out laughing haha xD
I know what you're thinking about... capital, well communism rule you bourgeois pig
I am embarrassed for not even noticing that.
Dr. Hannah Fry is just brilliant. I learned a lot from her. I wish she was my math lecturer.
theghostmachine dont you wish she was somthing more? XD *wink*
just watched a couple of her videos. Really starting to like her
That is not what I was thinking about when I clicked on the video
Me neither. I'd give her something big...
Big isn't better. Small ones last longer.
@@owenevans83 a big reason for a restraining order?

Yes you are correct, they got it wrong in the graphic but I think the concept holds.

Very informative, plus something about her voice really gets my attention.

That's great :-)

Something to do with the size of blood vessels etc

Them facts, that voice and not to be rude but very attractive as well. Your like a Quintuple threat!
I could listen to Hannah's voice all day:)
Head Squeeze deserves many more views than they get now. I simply can't wrap my head around it
Yes but should I fight 100 duck sized horses or 1 horse sized duck?
sth128 hhahaha i think i get it. its that game where you fight weird animals right??
+sth128 Definitely 1 horse sized duck. This vid gave you a clear answer if you listened closely ;)
6 years later: are you going to fight an orangutan once a year or a chicken everyday you go to work.
@@thethirdjegs Definetly orangutan once a year. From a strength standpoint you would obviously be able to fight one chicken per day basically forever, however it would get so fucking annoying I'd rather let the orangutan kill me.
@@Fuciskoare you a fellow from wild green memes for ecological fiends?
Last I checked f(x)=x^(3/4) doesn't look like the graph at 2:09
"Power is proportional to Mass^(3/4)" is right. The graph with mass on the x-Axis would correspond to the function f(x)=x^(4/3).
You've ruined ant man!
+Hokibukisa He's the worst superhero.
Love her voice!
How do you create those amazing animations that look like someone is drawing without seeing there hands?
I love these Number Hub videos so much!
I would disappoint her so hard.
we need more of her
More of her please!
Exceptional video by the way Head squeeze, I adore your channel.

Bing watching these videos
She's make an awesome weather girl.
im a prelaw maj. so it definitely flies over my head, still i get giddy when she presents a video
***** Please tell Mrs Hannah that her wisdom and beauty has reached Chile. Bloody Hell she's gorgeous.
She has an amazing voice. thanks for the video. i finally have some examples where big is not necessary better :)
omg that voice
Let's hope for the extra footage soon

Size to power graph is drawn wrong. Shows power increasing exponentially with size.
she has an amazing voice, i love it, i love it, sweet and beautiful, great explanation on size and great presenter.
does anyone else feel like she is exremely attractive?
Duh!
I do not usually replies to such comments, but I guess its a combination of physical beauty, intelligence, & classic English accent.
Why do you say anyone else?
Adam Miller Why do we feel the need to point it out is the better question. I'd argue that women make us react in different ways.
No, but she has a nice voice
More of this please.

How in the world was I seduced by a maths video?
What about rowing??? Everybody says rowers should be big and heavy but judging your explanation they should be short and light because rowing is endurance race (2-6 km depends on the race).
Indeed, an easy example of how weight has an effect is by looking at a cube of say..one kilo, make it 2x2 and you have a cube that is double in size, but is four times the weight, muscles are somewhat the same and they also have to support the body itself.
Her voice is actually really soothing me. Hell, I'm almost asleep.
A horse-sized duck of course! Can you imagine how awesome it'd be to ride it to work?!
I think the video would make the argument for 100 duck sized horses.
Thanks for this I had been thinking about this a lot before I found this video.🙂
I'd be listening to her for hours on end
Graph at 2:03- the axes are the wrong way around
Strength is more affected by your CNS than by your muscle size.
is this the 'who would you rather fight' version or the: witch would you want as a pet
I'm in love with your voice; obviously, not as much as I'm in love with science! :)
Is the graph at 2:10 correct? Doesn't look right to me. I would have thought it should level off as size of animal increases. The graph suggests that power increases exponentially with size.
I will be busting that out when someone starts telling me about ants and scaling up next time :D
Also structure makes a difference aswell
I love inteligent girls :D + the soft lovely voice and the perfectly red hair,it's just the perfect girl
Well done!
I agree with Dellenite
The title made my day.
well explained, shame about the graphics person not drawing the axis in the correct order! (unless that was some kind of inside joke)
I was thinking the same thing.
Best voice ever, just listen
Also why insects can fly despite having the aerodynamic elegance of a caltrop.
Thanks for replying!
Wow that's so cool! I'm trying to do the same thing, but it's really hard! Do you know the details about what kind of screen it is and what software you use?

this is an amazing discovery! a ginger with a soul!

Yes.
Yes*
this could be a stupid question, but would gravity and relative size have an effect on this topic?
With a voice like that, who needs short-distance relationships?
oh brother! totally
really great video, although ants are said to be able to lift even 100x their weight or more.
Like the info and the charismatic presentation, but dislike the undermining of my plans to get bitten by a radioactive spider and become able to lift seven times my own weight.
4:22 "An all brown nice chap"
Once heard it can't be unheard.
"all around nice chap"
I may have missed it but did you mention anything about Gravity?
100 mice vs the cat can only win if they have human intelligence.
So this means that there are three ways to measure strength: Raw force, force proportional to mass and force proportional to mass adjusted for size.
Can you discuss why yawns are contagious please?
I like this lady. She should make more videos for HS.
thats what she said!
Whatever sometime bigger is better 😂😂😂😂😂 I mean bigger the heart, good deeds etc
PFF!! Easy, horse sized duck would let me get on his back and fly away!
@4:32
Ohh my, that's cheeky.
Well done.
she's floating
I love her voice
Horse sized duck would break it's own legs
Clever video.
That's what she said...
its with the help of a kind of screen you connect to the pc and you draw on it and see it on the screen
She has a lovely voice :)
A horse sized duck. It's better to fight one target than be swarmed by a lot of targets.
Ok then for those who don't know Usain Bolt had a private party with the Sweedish handball team
So yeah that clears up that end statement
The Swedish Handball Team.
How did they come into the picture at the end?
Waz it a joke about "the real size" in the shorts? =)
This begs the age old question: a horse-sized duck or 100 duck-sized horses?
So this is what Hannah gets up to when not appearing on Numberphile. Interesting...
(just wanted to recognize she probs didn't come up with the title and this framing lol)
