[correction: in the last newsletter it was mistakenly written that UV  
rays are somehow related to television CRTs, that was meant to be two  
different statements that somehow, made it into one by accident. that  
is, the spectrum of light and its many forms have yet to be dealt with  
in an architectural context beyond their technical or scientific  
functions, versus a role of symbolism for that of the sun, which is of  
ancient and still traditional interpretations, post-modernism, even.
this is why a Newtonian worldview seems to drive architecture today   
moreso than Einstein's, and the physics and ideas of space/time/place  
related to it, and applicable to all things EM, networks, place, etc.  
in other words, architecture is obsessed with gravity and light in an  
era of nuclear war, cognitive science, supercomputers, fiberoptics.]

Have been intrigued by the question 'when was the first 'charge' in
the universe'? in relation to the astrophysics going on with models
of the universe. As it would seem 'life' cannot exist without charge.
Now wondering if there is any such a thing as 'the nature of charge'.

Prehistoric disaster linked to gamma rays // lost atmosphere...

	'The second-largest extinction in the Earth's history, the killing of  
two-thirds of all species, may have been caused by ultraviolet  
radiation from the sun after gamma rays destroyed the Earth's ozone  
layer.' .. 'Astronomers are proposing that a supernova exploded within  
10,000 light years of the Earth, destroying the chemistry of the  
atmosphere and allowing the sun's ultraviolet rays to cook fragile,  
unprotected life forms.'

IMF Researchers: US Budget Gaps Endanger Global Economy
By Joseph Rebello, Of DOW JONES NEWSWIRES // energy tax.

	'The White House has said it expects the budget deficit to expand to a  
record $ 475 billion in fiscal 2004, exceeding 4% of the gross domestic  
product. U.S. Treasury Secretary John Snow on Wednesday described that  
level as "entirely manageable," and said the Bush administration  
expects the deficit to shrink to 2% of GDP ( news -web sites ) within  
five years.' .. 'But the IMF researchers said that won't be enough to  
address the government's long-term fiscal problems - including  
financing the Social Security ( news -web sites ) and Medicare programs  
over the next 75 years. In their report, they said the government faces  
a $47 trillion shortfall in its ability to pay for those and all other  
long-term obligations. Closing that gap would require "an immediate and  
permanent" federal tax increase of 60% or a 50% cut in Social Security  
and Medicare benefits.' ... 'Congress and the White House can avert  
those dangers by acting immediately to balance the budgets, the  
researchers estimated. Allowing the recent tax cuts to expire by 2013  
would reduce the budget shortfall by nearly half. The researchers also  
said Congress should consider a tax on energy consumption, arguing that  
it would "help meet the administration's environmental objectives while  
also providing substantial support for fiscal consolidation." Such tax  
increases, they calculated, would have a minimal effect on U.S.  
economic growth.'

masterminding a web of schemes that hid Enron's debt, inflated profits  
and allowed him to skim millions of dollars for himself, his family and  
selected friends and colleagues. He has pleaded innocent and is free on  
$5 million bond. He has asked the court to move his trial, scheduled  
for April, out of Houston - preferably out of the state.' ... 'Lea  
Fastow, 42, was formerly assistant treasurer at Enron. She is charged  
with six criminal counts, including conspiracy to commit wire fraud,  
money laundering and four counts of making false tax returns. She has  
previously pleaded innocent on all counts.'

'Dirty Bomb' Was Major New Year's Worry // basic information needed.

	'With huge New Year's Eve celebrations and college football bowl games  
only days away, the U.S. government last month dispatched scores of  
casually dressed nuclear scientists with sophisticated radiation  
detection equipment hidden in briefcases and golf bags to scour five  
major U.S. cities for radiological, or "dirty," bombs, according to  
officials involved in the emergency effort.' ... '"Government officials  
are surprised that people [in the United States] aren't more hyped  
about all this," said one source familiar with counterterrorism  
preparations.' [NOTE: if people knew it was a dirty bomb, and what it  
was, people would have information to base judgements on. and, either  
react, in fear, or be prepared to deal with it, through knowledge.] ...  
'One of the U.S. officials' main fears was of a dirty bomb, in which a  
conventional bomb is detonated and spews radioactive material and  
radiation across a small area. Security specialists say such a weapon  
is unlikely to cause mass casualties but could cause panic and  
devastate a local economy.'

New Light-emitting Transistor Could Revolutionize Electronics Industry

	'A transistor usually has two ports: one for input and one for output.  
"Our new device has three ports: an input, an electrical output and an  
optical output," said Feng, the Holonyak Professor of Electrical and  
Computer Engineering at Illinois. "This means that we can interconnect  
optical and electrical signals for display or communication purposes."'  
... 'Although the recombination process is the same as that which  
occurs in light-emitting diodes, the photons in light-emitting  
transistors are generated under much higher speed conditions. So far,  
the researchers have demonstrated the modulation of light emission in  
phase with a base current in transistors operating at a frequency of 1  
megahertz. Much higher speeds are considered certain.' ... '"At such  
speeds, optical interconnects could replace electrical wiring between  
electronic components on a circuit board," Feng said. This work could  
be the beginning of an era in which photons are directed around a chip  
in much the same fashion as electrons have been maneuvered on  
conventional chips.'

Wozniak, Motorola May Work on Tracking System

	'Mr. Wozniak's closely held company -- dubbed Wheels of Zeus Inc., or  
WOZ -- is developing a system that uses low-cost radio tags that could  
be attached to objects, people or animals. By combining satellite  
location-finding technology with radio base stations, the tags could  
help consumers or companies protect goods against theft and ensure the  
safety of children and pets, Mr. Wozniak said.

Eyes on the Pries : Why surveillance technology
should worry even those with nothing to hide.

	'Think about the huge life events and decisions that hang on the  
strength of your credit rating. Now, what if the government were to  
give us similar ratings? And what if for some seemingly arbitrary  
reason (a skinny-dipping citation, a few unpaid parking tickets, or an  
expired dog license) you wind up in a second- or third-tier  
classification? In a sense, argues Rosen, "risk profiles extend harms  
similar to those imposed by racial profiling across society as a whole,  
creating electronic layers... that determine who is singled out for  
special suspicion by state officials."'

Cleaning Up: Bush's Pals, an Oligarch,

Hydrogen's Dirty Details

	'Gerard is right: The so-called hydrogen economy will be a boon for  
the mining industry. The clean-energy future that many  
environmentalists have dreamed of has been turned over to the coal  
industry and a notoriously dirty Siberian mining company run by Russian  
oligarch Vladimir Potanin. A deal personally smoothed over by Bush has  
given Norilsk Nickel, one of the world's worst polluters, a toehold on  
American soil—and a major stake in the hydrogen economy.' ... 'The  
coalition favors the use of wind and solar energy to power the  
reactions that extract hydrogen from substances like water. But to  
build the hydrogen economy over the next 30 years, Republicans are  
instead planning to burn more fossil fuels and dig for coal and gas on  
public and private lands. The Green Hydrogen Coalition noted that the  
GOP-written Senate energy bill called for subsidizing the nuke and  
fossil fuel industries to the tune of $8 billion, twice the amount set  
aside for renewable energy sources.'

	'A conference schedule made public by an environmental group indicates  
that in addition to Western members of the House and Senate, the  
conference is to be attended by several high-level Bush administration  
officials.' .. 'Participants will pay $3,000 to play in a "Mulligans  
and Margueritas" golf tournament and attend a private dinner tonight  
with congressional Republicans. The proceeds will go to a Republican  
fund-raising committee.' .. 'The conference on energy and air-pollution  
issues will follow during the next three days, held by the Western  
Business Roundtable and the U.S. Chamber of Commerce.' .. 'The  
conference will focus primarily on congressional issues of concern to  
Western industries, but anyone willing to pay around $1,000 for  
registration and greens fees can attend the three-day event. It begins  
tonight, right after the golf tournament.' .. 'Invited participants  
listed on the schedule include Undersecretary of the Interior Steven  
Griles, Environmental Protection Agency Assistant Administrator Jeffrey  
Holmstead, White House Counsel on Environmental Quality Chairman James  
Connaughton and Assistant Secretary of Energy Michael Smith.' .. 'The  
organizer of the two events insisted they were separate.' .. 'Both take  
place at the Arizona Biltmore Resort and its golf courses, and are  
organized by Denver-based lobbyist Jim Sims, who was director of  
communications for Vice President Dick Cheney's White House Energy Task  
Force three years ago.' ... 'The goal is to make sure the West's  
interests are factored in when Washington writes energy and  
environmental policies, Sims said.' .. '"We prefer to think we are the  
nation's energy breadbasket, and we are," Sims said.'

Study: Universe lifeless after Big Bang // beautiful short story...

	'The first stars after the Big Bang were immense, superhot giants that  
lived briefly and then exploded as brilliant supernovae, but they  
seeded the universe with basic elements that were the building blocks  
for the sun and the Earth, and for life itself, according to a new  
study.' ... 'Supernovae continued to explode, seeding the universe with  
more and more heavy metals. Eventually, there were enough of these  
metals to create long-lived stars and for planets to accrete into their  
orbits. On at least one planet, the Earth, all the ingredients came  
together in the right place and time for life to evolve.' .. '"The  
window for life opened sometime between 500 and 2 billion years after  
Big Bang," Loeb said in a statement.'

	'Poincare made strides in understanding three-dimensional spaces - the  
kind, for instance, that an airplane flies through, made up of  
north-south, east-west and up-down measurements. His question, or

Subatomic Tracking Finds Clues to the Unseen Universe // muons...
	'An experiment that tracks subtle motions of subatomic particles  
called muons has found tantalizing evidence for a vast shadow universe  
of normally unseen matter existing side by side with ours, scientists  
at the Brookhaven National Laboratory said yesterday.' ... 'The  
existence of the new matter is predicted by an unconfirmed theory  
called supersymmetry. According to the theory, every known particle in  
the universe from the electron to the neutrino has a counterpart that  
has eluded detection. Some versions of the theory suggest that "dark  
matter," a substance that seems to outweigh ordinary matter in the  
cosmos, actually consists of tremendous swarms of supersymmetric  
particles that waft through space.'

Researchers Develop First Integrated Silicon Circuit
With Nanotube Transistors

	'Depending on the molecular structure specific to each carbon  
nanotube, it can either be metallic and capable of conducting  
electricity, or act like semiconductors, with conductivity that can be  
turned on and off.' ... 'The resulting chip contained thousands of  
carbon nanotubes connected to the circuit on a 1-square-centimeter  
silicon chip. By turning certain switches on and off, researchers were  
able to isolate the path that leads to an individual nanotube. Not only  
could researchers pinpoint which nanotube was responding to electrical  
current passing through the system, they could tell whether the  
conductivity could be turned on or off. If they were able to change the  
conductivity of the nanotube, they knew that it was a semiconductor and  
not metallic.'

analysis by the Intelligence group after landing.' ... 'It is reported  
that response times between sensor activity and mission strike could  
occur in as little as five minutes, but it would not have been  
considered prudent to so precisely 'telegraph' the sensor locations to  
enemy intelligence by such cause-and-effect activity. Although it did

Let There Be L.E.D.'s // better lighting could change everything...

	'The research into solid-state lighting is motivated by light bulb  
makers who want to create new and profitable products. But saving  
energy is a consideration, too. About 20 percent of all electricity in  
the United States is used for lighting. A shift  from bulbs to L.E.D.'s  
and other more efficient kinds of lighting could cut that percentage in  
half, easing the strain on power systems and reducing the chances of a  
blackout like the one that affected the northeastern United States and  
Canada last August.' ... 'The incandescent bulb, which works by heating  
a thin metal filament so that it emits light, is also inefficient.  
About 90 to 95 percent of the electricity that goes into most  
incandescent bulbs is converted to heat rather than light.' ... 'The  
major barrier to creating inexpensive L.E.D. lights for homes is not  
the semiconductors themselves. The real obstacle is the cost  of  
overcoming several basic limitations of the chips.'

Techno hits basic beat
Musical analysis unveils a hierarchy of sophistication.

	'Heather Jennings of the Federal University of Alagoas in Brazil and  
her colleagues conclude that Gamelan - an Indonesian style of music  
featuring gongs, drums, wind and string instruments - is as  
sophisticated as Western classical music in terms of its variations in  
volume. And both of these styles tower in complexity over modern techno  
tracks and Forró, a form of traditional dance music from Brazil.' ...  
'Acoustic scientists studying complex sounds typically measure their  
'power spectra': a measure of the patterns with which volume changes  
over time.' ... 'But power spectra are rather crude measures, Jennings  
and colleagues say, and can hide some of the complexities of different  
musical forms.' ... 'To get around this, the researchers fed  
four-minute stretches of music into a more sophisticated technique,  
called detrended fluctuation analysis (DFA). This has been used in the  
past to study complicated signals in economic, genetic and heartbeat  
data.' ... 'The method produces a number, denoted alpha that quantifies  
the complexity of patterns in a signal - in this case, the volume of  
music. A low alpha (less than 1) indicates relatively non-complex  
music, whereas more complex musical signals have a value of alpha  
closer to 1.' ... 'Gamelan has average values of alpha closest to 1, as  
does what the researchers characterize as 'new age music'.'
