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.

2. Making Stuff: SMALLER

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

ALIENS AND DEADLY WEAPONS

http://www.imdb.com/title/tt1643266/

Excerpts:

"In the Mahabharata, 46 different types of weapon are described.
They're using air-to-ground missiles, powerful particles beam weapons."


"but each culture always says that fire is a gift from the gods.
In native American traditions quite often
it's fire was stolen from the world above .
In Moari legends, again, we see the theft of fire from the gods.
In the Greek legends it's Prometheus
stealing fire from the gods.


"Approximately 1000 years after the development of iron,
human came another, even greater breakthrough:
The invention of steel.


To make a steel sword in ancient times was not an easy task.
You would have to get high quality iron.
and most of the times they could not get that iron mined from the earth.
And meteorites were obtained, which were pure iron, which
made the best steel swords.
AND THESE WERE CONSIDERED MAGIC SWORDS.
And they wre usually a guarded secret, and villages would have
one or two steel swords.


Tsoukalos: I refuse to think that our ancestors,
came up with these stories out of thin air. (story of Mahabharta)


BRAHMASTRA - A WEAPON TO DESTROY THE UNIVERSE

But of all the weapon described in in the Mahabharata, perhaps the most deadly was device called
the Brahmasrta.
A weapon that the texts warned was never be used.
Brahmastra is described as the ultimate weapon.
Once it is launched, it will simply burn everything,
so it will incinerate the entire universe.
We are talking about a nuclear blast 100-fold magnitude of the bomb
that we have seen or experienced in our own times.
So it would never be used.
And yet, someone was going to make use of that Brahmastra.
And so that's the dilemma that the books talks about in the Mahabhrata.


Preah Pisnokar, Combodia
Sword of Light/Beam/Laser

"The plasma beam really is energetically charged particles
with a lot of energy and pretty much cut through anything."
