Is it just me or is her voice so soothing
I find her voice obscenely sexy.
i could listen to her all day
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.
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.
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!
You've ruined ant man!
+Hokibukisa He's the worst superhero.
Her voice! It's so soothing.
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?
Love her voice!
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
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)
A horse-sized duck of course! Can you imagine how awesome it'd be to ride it to work?!
Size to power graph is drawn wrong. Shows power increasing exponentially with size.
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
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).
Horse sized duck would break it's own legs
She's make an awesome weather girl.
Let's hope for the extra footage soon
I'm in love with your voice; obviously, not as much as I'm in love with science! :)
PFF!! Easy, horse sized duck would let me get on his back and fly away!
Also structure makes a difference aswell
this could be a stupid question, but would gravity and relative size have an effect on this topic?
I love inteligent girls :D + the soft lovely voice and the perfectly red hair,it's just the perfect girl
she's floating
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.
This begs the age old question: a horse-sized duck or 100 duck-sized horses?
I may have missed it but did you mention anything about Gravity?
well explained, shame about the graphics person not drawing the axis in the correct order! (unless that was some kind of inside joke)
The title made my day.
Whatever sometime bigger is better 😂😂😂😂😂 I mean bigger the heart, good deeds etc
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.
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.

How in the world was I seduced by a maths video?
I suppose it's not possible for a human to be both a very good Marathon Runner and a Sprinter??
I prefer the sprinters body even if there endurance is not as good as a long distance runners.
100 mice vs the cat can only win if they have human intelligence.
She is awesome! :) Well explained!
Clever video.
Best voice ever, just listen
does this mean that a man who is 4 ft tall would be stronger than a clone at 6 ft tall?
Now that's an easily misinterpretable title...
Does this translate to inanimate objects like tanker ships and rockets?
She has a lovely voice :)
I think a channel of her doing nothing more than counting numbers may be in order. No? Ok.
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? =)
I must say that I really liked the video...BUT! the voice, damn, is gorgeous
That's what she said ?
Exelente!!!!
don't*
Yeah I was made because I wanted to really know what the strongest animal is for it's size. I don't want to hear that some really small animal is strong for it's size when it's only able to lift so many times it's one weight because it's little. 😒 Make them the same size and then do the math to find out which is the strongest for it's size! or it's a shame!
video's title is misleading :)
Nice voice, do more vids with her
So really we're limited by oxygen? I have heard of the concept that if insects grew in size they wouldn't function. I guess I'll need to watch this video again because I have been wondering for a while about this. Or someone could simplify it for me : p
my girlfriend can't help saying bigger is better! shall i woory?
+Daniel Evrard Tell her that a smaller one is more efficient, and that the bigger it is, the more likely that the male will die if it gets erect. Seeing as after a certain size, the 6litres of blood isn't enough to keep you from falling unconscious.
LOL, really you thought calling it that was a good idea...
or we could just stick to what we do now, the much easier option of stepping on them xD
What if u/something else where twice as big
How exactly do you get 8 times bigger? You get 2x bigger in height, width and depth but what else?
With a drawing tablet! :)
I need more of your voice... *Subscribes*
i love you hannah
Aight, so she said ants breath through osmosis. I thought ants breathed through diffusion,
Now osmosis is just the diffusion of water...so did she mean diffusion or do ants actually take in water through their skin and breath like that?
Osmosis is diffusion though a cell membrane. Water is the most common solvent, but not the only one.
swedish handball team? i dont think i get it?
bolt had a hotel party with the swedish womens handball team at the 2012 olympics
ty
So, "Tarantula" was bullshit?
You are iggy's red headed more intelligent, sexier twin.
oh wait, dUck!
What does she exactly say at the end of the speech? Something about a "sweedish handball team", do I hear right? Looks like a joke but I don't get it...
+Jordi Garcia Yes you heard right. www.mirror.co.uk/news/uk-news/usain-bolt-parties-with-three-of-the-swedish-1230004
+LiamE69 Thanks LiamE69... but what does she exactly say after "bigger it's not always necesseraly better"?
+Jordi Garcia "bigger is not always necessarily better but try telling that to Usain Bolt and the Swedish Handball team."
+LiamE69 Thanks!
The end was pretty corny
i thought this video would be about something else....
:) I love your voice
vsause
I may have subscribed if it weren't for that last comment...
Why the hell was this posted into the James May topic in a ploy to get me to watch this? Pathetic.
I'd be perfectly willing to perform experiments with her to determine the answer to the title of the video.
1 cat vs 100 mice..
well, my money is on the cat.
and to the comments below..
haven't you nerds seen a woman before?
control those hormones ffs.. lol
omg that whole time im like, wow she is so pretty and then she had to go do the Bolt stance and it was soo cringeworthy.
Hehe LoL :'D
missleading title for the dirty minded
Are you sure that's even female?
Iggy Azalea bish!
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.
just watched a couple of her videos. Really starting to like her
I would disappoint her so hard.
Hannah just destroyed my hate for math and numbers and replaced it with love, joy and happiness.
Abersanbn
That's great :-)
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).
***** Please tell Mrs Hannah that her wisdom and beauty has reached Chile. Bloody Hell she's gorgeous.
omg that voice
Very informative, plus something about her voice really gets my attention.
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
Something to do with the size of blood vessels etc
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
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*
Bing watching these videos
With a voice like that, who needs short-distance relationships?
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. :)
This title is a bit obnoxious. Surprised that it's coming from something affiliated with the BBC.
Yes you are correct, they got it wrong in the graphic but I think the concept holds.
How do you create those amazing animations that look like someone is drawing without seeing there hands?
she has an amazing voice, i love it, i love it, sweet and beautiful, great explanation on size and great presenter.
