EXCERPTS:

1. Making Stuff: STRONGER
http://www.imdb.com/title/tt1717371/


In the quest to find the strong materials
STEEL is the great place to start.


Iron is the main ingrediant in steel
but steel is stronger than iron
because it also contains carbon.


... and it becomes standard
for soldiers, swat teams, bomb disposal squads,
I'm talking about KEVLAR.
When this synthetic is woven in fabric,
Kevlar is strong enough to stop a bullet,
or a blade, or even with few chemical changes, a fire.


1930, Japan seized silk supplies - a metrial used to make parachuts and flake jackets.
1935, Wallis ... created NYLON - first fibre made in test tube, not in nature.
1960s, Stephni Pullock chemist, created Kevlar, it remained the strongest fibre ever produced.


Kevlar is a polymer - a long repeating chain of atoms,
in this case, C, H, O, and N.
each is like a stiff piece of spaghati.


NANO-TUBES


SPIDER SILK
more tensile strength than steel,
and Kevlar.
It can strecth to 140% in its length without breaking,
and remain flexible even in extreme cold.
It also so light weight.


Spider Goats.
Goats which are modified gentically by putting spider's spider making genes into goeats.
Goats now give milk with spider-fibre protein.

Solid Mineral Quratz
Slice a piece of quratz small enough
send a electric current trhough it
and it vibrates, fast.
a quartz driven clock is accurate chopped time in millionths of a second.
But the biggest selling point of quartz is that its cheap.
That because quartz is actually silicon.
common place sand - the second most abundant element on Earth.


A billion switches on a one inch chip!


Vertical Transistors


Graphine
a revolutionary material
Two Russian Scientists, The Noble Prize in Physics 2010


Capsule Camera
The Pill Cam
travels through the body just like a piece of food
taking 55000 picturs over the course of 8 hours.


Bee Venom
Cancer Drug
