Bible imagery - can we learn anything from history
Prior to the Civil War, the south was losing to the north’s industrialization and resulting wealth. Slavery was not popular among both groups. The south could not get back their former power through technology change. The south believed they could get back their former power through slavery. The south privately knew that slavery was not sustainable, but their pride would not allow them to accept the poverty status they were in. The end result was a Civil War over the issue of slavery. The south could not use slavery to maintain their power. When empires become rich by inflation, people become dependent, morality decays, consumer spending becomes excessive, and entertainment rules supreme; but liberty is lost. Empires require the support of the people. The real wealth of the middle class declines in an empire. It is during periods of high economic volatility that politically dominant groups transfer the cost of warfare and social programs onto the working class and class division forms. More middle class individuals move into poverty, while more middle class wealth transfers to the top echelons of society.

Bible imagery - stand for liberty
Russia, with the help of China’s money, will win the war against the Ukraine. America has known there exists no missile shield against a Russian first strike missile attack. The U.S. will enter into a world war against Russia as it attacks with nuclear weapons the eastern coastal U.S. cities. Russia will lose the ground war to the U.S. and it’s allies and cease to exist as a political and economic entity. The ground war will spread across the world including North Korean ground troops. There will be some fighting in America against North Korean ground troops transported by Russian aircraft to five airports which the Russians know how to navigate.
Chinese troops will march from Canada down through Washington into California. The primary goal of these troops is to open a trade route for agriculture goods from Idaho, Oregon and Washington. This region will be known as the United Nations biosphere. Large corporate control of these resources will be managed by the Chinese. Chinese troops will push upward through Mexico. The U.S. army will have some victories but become exhausted. The final rescue will come from the lost tribes within Siberia who will realize the evil that has befallen America. The soldiers will arrive helping the U.S. Army defeat the Chinese and the North Koreans.

Bible imagery - we can be happy
As captivity in Babylon feels hopeless and cold to those not seeking God, we can feel warm and comforted by knowing and feeling that God loves us and he is aware of us. Christ can smile upon us and heal our broken hearts. He can bring understanding to our minds. We can see a better way of living. We can help others in need and have joy in service to others. We can give of our money to help others. We do not need to feel afraid of scarcity. We can invite others to our home to learn of their interests and their challenges in life. We can become connected to the human family. We can learn what it means to be human and compassionate. We can gain deeper insight into the dynamics and perspectives of others as intelligent and dynamic children of a loving God. We can be happy.

Bible imagery - the corporate god
God’s mysteries are deep, and He only can reveal His mysteries for the hard questions in life. It is not our job to explain to others the mysteries of God. Many are just for our own use and understanding. Occasionally, if the circumstances are right and we feel safe in sharing our personal experiences and understandings, we can do so to edify others in need. We learn the mysteries of God because of who we are. We can ask questions of God, expecting answers over time because God loves our experiences, insights and good works.

The quantum cellular automata - the race to replace the transistor
Quantum scientist have also shown that an array of Single electron Transistor - SETs create a form of neural network." SETs construct computers that use individual electrons to carry information. SET biggest problem is operating at room temperature. Quantum tunneling means the can "interact capacitively rather than by current flow throught the wires." "When their interactions result from the quantum tunneling of electrons, quantum dots can collectively behave as a form of quantum cellular automaton, QCA. QCA computers may show associative memory. If Decoherence can be avoid a qbit can form with a 0 or 1 or superposition state of both at the same time. 5 qbits could handle 32 states (2^n), simulateously; a conventional computer would handle 32 sets of 5 bits, or 160 bits in all. 64 bit encryption could be processed with one 64 qubit operation, whereas, a conventional computer requiring 2^64, 1.84 x10^19 operations or 292.5 years, 18 billion billion times more powerful than a 64 bit binary computer.

Understanding Nanotechnology Quantum Dots , Colloids , Cantilevers , Dendrimers , Nanoshells
Quantum Dots contain only a few hundred atoms. Because the electrons in a quantum dot are confined to widely separated energy levels, the dot emits only one wavelength of light when excited. The size of the dot determines its electronic, magnetic, and optical properties. Quantum Dot Corporation has developed a QD cadmium selenide nanoparticle for use as biological labels. Researchers can tag proteins and nucleic acids with QD and illuminate them with ultraviolet light and the crystal will fluoresce at a specific wavelength and show the location of attached proteins. How does a QD work? An organic dye molecule absorbs only photons of light with just the right energy to lift its electrons from their quiescent state to one of the higher levels available to them. The incident light must be exactly the right wavelength or color. The molecule will emit a photon when the electron falls to a lower energy level.
Colloids: nanoparticles in suspension. IBM is exploring using colloids to build ultrahigh density data storage. IBM is using colloids containing magnetic nanoparticles 3 nm across, each composing of about 1,000 iron and platinum atoms. The colloid is spread on a surface and the solvent allowed to evaporate and these nanoparticles crytalize into 2 or 3 dimensional arrays. These arrays could hold trillions of bits per square inch.
Cantilevers: IBM is exploring using atomic force microscopes to screen samples for certain genetic sequences. They attach short strands of DNA to the tops of cantilevers. When genetic material carrying a complementary sequence binds to the anchored strands, it induces a surface stress, which bends the cantilevers subtly, by use nanometers, but enough for detection.
Dendrimers: An dendrimer is an artifical molecule. Dendrimers are globular molecules about the size of a typical protein, but they do not come apart or unfold because they are held together with stronger chemical bonds. Dendrimers can be engineered to transport DNA into cells for gene therapy. Dendrimers offer control. It may be possible to design dendrimers that spontaneously swell and liberate their contents oly when the appropriate trigger molecules are present. This ability would allow a custom-made dendrimer to release its load of drugs I just the tissues or organs needing treatment.
Nanoshells: Nanoshells are extremely small beads of glass coated with gold. Nanoshells capture energy in near-infrared fashion. Such a nanoshell could be made to deliver drug molecules at specific times by attaching it to a capsule made of heat-sensitive polymer. The capsule would release its contents only when gentle heating of the attached nonshell caused it to deform. Another more dramatic application envisions connecting nanoshells with antibodies. The antibodies attach to the tumor cells and the nanoshells are heated using high power infrared sufficiently to destroy the cancer cells, while leaving nearby tissue unharmed.
