Science Any Good? Seven Ways You Can Be Certain
It by putting molecules which will swell or shrink you can cinematographer do wonderful things okay I have about five minutes yeah so I want to finish by now basically telling you about not only using origami to understand biology but showing you how we can use biology to maybe do other things.
I told you Bohr Akita Introductions of wet origami and in facts few years ago we looked.
At conspicuousness partly by origami but just out of curiosity how many of you know throatiness can essentially close everybody knows that they will be open because you see them outside but a few people.
How To Leave Science Without Being Noticed
over here know close you just put them in water and they will close alright now let me show you so here’s a pine cone you just throw it in water and this is a time-lapse image which essentially.
Is associated with doing it over many hours and it closes and then you take it out and it opens and you can do this as many times as you want okay the reason that this impossible is associated with the fact that at the base of every pine cone bract that’s the name for these leaf length structures you have little fibers which swell when they essentially are in contact with water and then they shrink when they dry out and that’s exactly what we’ve been showing you over here okay so knowing that in fact and knowing.
That paper is the same as wood it’s just treated wood and so wood can swell and shrink and you knew that you know that of your paper back when you leave the min the kitchen or in the bathroom for too long there is this wonderful architect Christian Gib ran who basically now created a printer where the printer essentially paints or prints the fold sand also puts water and as this sheet of paper comes.
out it falls itself okay so here is an example where knowing what that paper will swell and shrink and doing a little bit of very clever engineering now you can essentially get these things to fold.
