The Denver Science museum has a wonderful ten foot HDTV projector. When this is used with the special educator DVDs from JPL, which have superior images to those downloadable from the web, the results are wonderful. The large screen has an immersive effect and you FEEL like you are looking out of a window at Mars.
However my main complaint is that some of the curators truncate the Rover images and show the launch videos and animations over and over. This is because some patrons complain about the "boring pictures of rocks"!
I think they got really suspicious when the voting machines kept on electing George W Bush to office, even though he wasnt on the ballot. Some voting machines intended for Florida accidently got shipped to Dublin.
Its interesting to look at "future prediction" books written decades ago and see what was correct and what was missed. Early futurists were concerned about machines- robots, personal airplanes and rockets. Didnt quite predict airline travel would become mass market like "greyhound in the sky". Then in the 60s and 70s the future became "human potential": ecology, the new psychology, etc. Then int he 1980s the future became IT everywhere.
You see these images of the future fossilized in the Disney parks, depending on the when the attraction was built, e.g. Tommorrow Land, Carousel of Progress, EPCOT Dome, etc.
When I was designed circuits in MITs digital lab in 1975, 1K of RAM cost $50 ($200 in 2004 dollars). There was only bi-polar static RAM then. It was relatively fast too.
Both the Mediterranean and Black Sea appear to have been dry at times. The Strait of Gilbraltair is not very wide and periodic tectonic movements may have cut off the Atlantic. There are salt deposits on the Mediterranean floor, idicating dry periods. Ditto the Bosphrous strait into the Black Sea. Plus recent submarine surveys suggest village settlements deep into the Black Sea.
The problem with Mediterranean is the timing. The dary periods maybe a couple million years ago- too early for human culture. The Balck Sea is a better candiate with a dry period possibly just 20,000 years ago.
At their Colorado series last summer you could subscribe CD-ROMS of their concert the next day. The y contracted some techie to produces these. (They are scheduled for several days at Red Rock in 2004.)
In some libraries (and bookstore chains) I have wade through shelves of CDs, videos, computers, and art displays before I even see some books.
And how do I know about how many libraries look like? In other cities I frequently go to the public library to catch up on my email and other net surfing. They are easy to find than cafes and kinkos (in USA).
The shroud of Turin was carbon dated, twice with controls. The controls were pieces of fabric from different centuries. The controls dated as expected. Plus the shroud dated to the 14th century.
However there still is lots of spin of how the carbon dating method could have failed, or succeeded.
There seems to be a new TV special practically every year rehashing the old arguments and adding the new.
JPL has been marketing a fiber optic "gyroscope".
It using inferometry in long fiber loop. Motion will cause a loop of light to doppler shift out of phase. Four of these coils, each on the face of a tetrahedron, will measure any rotational motion.
No parts to break or wear out.
I presume NASA spacecraft are using mechanical gyros?
I recall some incident in the 1980s about college professors manufacturing textbooks out of journal articles for classroom use. This was found to illegal and resulted in xerox machine restrictions for a while- some where moved to restricted areas in libraries. Some journals would print "send me money" notices on the first page of articles giving the cost and address of making a copy. I think this was more policed at places like Kinkos rather than personal copies.
Any of the four combinations of parents should be possible then. Its been known for some time that parental chromosomes retain parental markers. The two mother experiement made female chromosomes look male.
The recent book "The X Chromosome" has several interesting chapters about the slight differences between the parental chromosomes. The cells in a female body mostly disable the second X chromosome. The disabled chromosome actaully separates into a chunk called a Barr body. Most of the time, only one parental X is turned off. But in some cases a female is a genetic mosaic with the mother-X turned on in some tissues, and the father in the other. It is thought this might partly explain why females have a much higher incidence of auto-immune diseases like lupus: Some have two different genomes expressed and each side attacks the other.
A small fraction of children may have the wrong number of X chromosomes- from 1 to 4, plus maybe a Y. There may be some gender anomalies. But because the extra X's are mostly turned off, it is not fatal.
Due to the warping of space by the mass of the earth an orbit is about 1" smaller than PI times the diameter. Very small, but potentially detectable effect.
Gaseous hydrogen quickly oxides into water vapor, which in turn traps heat energy in the atmosphere. I havent been able to find a comparison of the potency of hydrogen and carbon dioxide. Being the smallest molecule, dihydrogen leaks the most easily from containment systems. Some people have speculated that large amounts of hydrogen could leak and contribute the greenhouse problem.
Stanford hysics prof Everitt has been working on this project for 40 years, out-living his two co-investigators. The physical resemblence of Prof Everitt to Einstein is striking. Everitt always had a mustache and scragly-long 1960s hippee hair. Now it has turned white, he looks like Einstein.
US agriculture consumes vast amounts of petroleum directly for tractors/transport and indirectly as fertilizer feedstock. Without petroleum yields would plummet. The imports import 60% of its petroleum needs currently, jumping to 95% by 2020.
My computer was slowing down, with increasing popups until I realized the problem. Now I check every week. I NEVER click inside and a web advertisement.
Some had fake window frames that executed code.
Some physcists such as Alan Lasserby suggest mysterious forces can be explained by slight pertubations of Euclidean geometry on a universe-size scale. This could explain the anti-gravity force called "dark energy". Its thought to compromise 70% the "stuff" in the universe, but obliviated by a geometric explanation.
The devil did his work by appealing to one's intellectual arrogance- "I'm too smart for that". Sounds familar? The devil has lots of opportunity in the modern world when knowledge is a prized commodity.
These were stories writen in a non-sequential order.
You had to flip to another page at the end of a section. Sometimes you had more than one choice.
Some instructional material wa written this way. It got rather annoying. I prefere the "expanded outline" type. You only go into the detail you think you need.
People who claim holier-than-thou that they watch "almost no tv" are full of it. Scratch a little deeper and find out people watch moe than they claim.

One year of calculas is a school-wide requirement, even for the 20% who do not major in science or engineering.
I took some calc courses at the local community college while in high school. All three together barely reached the first semester.
Just wait for cars with hydrogen tanks!

"A person who becomes immensely rich off an IPO." Literally it should be 1 followed by a hundred zeros, but more reallistically about ten zeros.
