Of sort of so, let's on this video by throwing a mouse, the dog and an infringement skyscraper onto something something, let's say a stack of mattresses, the mouse lines- and this done for a moment before it shakes itself off the walks away. Pretty annoyed because that's a very rude thing to do the don't break sort of it's bones and dimes an unspectacular way and the innocent explodes into a red puddle of buttons and and science and has no chance to be annoyed. Wind is the survive, the innocent and dogs, don't the onset his size. This is the most under appreciated to regular user of living. 

Things sunnis determines everything about how biology, however, bills, how we experience the world how we live and die. It does so because the physical laws, a different food, different sized animals, life spans, seven orders of magnitude from invisible bacteria to mice and mice, dogs, humans, innocence and blue whales. Every site, slaves in it's own, unique, universal right next to each other. Each with it's own rules, upsides and downsides, will explore these different worlds in a series of videos.

 Let's get back to the initial question why he denounces survive the full because of how scaling size changes, everything the principle that will meet over and over again very nice little things, for example, I'm practically immune to falling from great heights, because the smaller you are, the less you care about the effect of gravity. Imagine a theoretical, spherical animal, the size of a marble. It has three features, it's length, it's surface area which is covered in skin and it's volume for all the stuff inside it and like folding his muscles hopes and dreams. 

If we make it ten times longer say the size of basketball, the rest of it's features than screw ten times, it's skin will grow one hundred times and it's insides choice. Volume grows by one thousand times the millennium determines to wait for more accurately mess of the animal them. Last you have the higher your kinetic energy before you hit the ground and the strove with the impact shock. The most surface area in relation to your volume or mass you have the will. The impact gets distributed than suffering and also the will and resistance will slow. 

You down an innocent is so big that it has extremely little service area in ratio to its williams, so enough of kinetic energy gets distributed over a small space and the ad doesn't slow it down much into that. That's why it's completely destroyed in an impressive explosion of do with it hits the ground. The other extreme insects have a huge surface area in relation to that tiny mass, so you can actually throne and from an airplane, and it will not be seriously harmed.

 But while fooling is relevant in the small world, there are other forces to the homeless for us, but extremely dangerous for small banks like surface tension which turns water into a potentially deadly substance.
