|From the star wars homepage. Yoda|
is a Jedi Master, and supercute. I want
one for christmas!
Einstein showed that time and space are malleable structures whose appearance depends on the observer's motion states. This truth was further developed, space and time can also be distorted and bent due to the presence of matter or energy. Gravity can move from one place to another. It sounds like something one learns from Yoda in the Jedi school on the planet Coruscant (for those of you who may be Star Wars).
"String theory is, strictly speaking, the history of space and time since Einstein. Most of us take for granted that our universe has three spatial dimensions. But that is not according to string theory, which argues that our universe has many more dimensions than those we see, the dimensions are tightly curled in the universe ‘s pleated fabric. "
Jedi Knights are taught that not everything is as it looks. This seems to be correct according to modern physics. How many dimensions are rolled up right in front of us? The physicists have worked on this and the number of "extra" dimensions have varied over the years. Right now it is believed that there are 11 dimensions all in all, including our three dimensions and time.
How to relate the string theory to our world that we see and can interact with? Matter consists of atoms which in turn are composed of quarks and electrons (there are a whole bunch of different small particles). All these particles are actually tiny vibrating strings. What has previously been seen as a point, is now perceived as a movement. The string theory explains distinct characteristics of various small particles that these reflect the different ways that a string can vibrate.
Everything is dancing to different rhythms, like Robyn sings the song "We Dance to the Beat". String theory seems to be the longed-for "theory of everything". I have read some physics at university level but despite that string theory is more understandable when I think about what they are talking about Star Wars. Yoda would fit up there on the podium.

There is an associated site to Brian Greene’s work called The elegant universe. It conveys knowledge of the vibrating universe we live in, here are videos and information for teachers who want to use them in their teaching;

Apple seed and apple thorn,
Wire, briar, limber lock
Three geese in a flock
One flew East
One flew West
And one flew over the cuckoo's nest
This is the rhyme that inspired the book and later the film "one flew over the cuckoo's nest" (according to wikipedia) about institutionalization of the human mind. You could say that mental illness and creativity does the opposite, deinsitutionlize it, liberates it. I might be the same neurological processes that are involved, and if so why is it expressed in different ways in different humans?
I am just playing with the how future of psychiatry could look. Instead of trying to kill whatever processes we think are responsible, could their expressions be manipulated? I know people who rely on neuropharmacological treatment to be able to leave their house so I am not having a go at the medical industry (well maybe a bit). I am playing with the thought of instead of hitting what we want to kill, we could hit something that change how the process is expressed in the individual. Can it be supported and other pathways be manipulated...
Yes it is way out and probably wrong....outside the box...hmmm.....should I be worried?

In Europe we watch TV 3 hours a day, Americans watch 5 hours a day. Western culture with all it’s amazing gifts have become more and more focused on “friction less living”. TV is a great tool to educate us and be used for catharsis and entertainment, but 5 hours a day? Now scientists are sure.
"Prolonged TV viewing is associated with increased risk of type 2 diabetes, cardiovascular disease, and all-cause mortality.”
3-5 hours a day is prolonged viewing, we are killing ourselves. TV is a drug. If we can forbid and limit access to drugs and alcohol because it serves the interest of the citizens and their health, why should there be a TV in every house? The drugs, just like TV holds promise of entertainment and aiding good health and catharsis at a limited use (I am not saying that we should do drugs, I have seen firsthand how it can kill and destroy people so I would be the first to suggest caution).
Why should we have a TV in every flat, when we are not allowed to access alcohol or drugs with the same convenience because of the possible danger they posses? Why are some drugs ok? I am just looking at the data, I am not advocating the use or non-use of drugs. Almost everybody is a druggie...we just use different drugs to numb ourselves or liberate ourselves from whatever is going on in our lives. In the future, will the TV come with a warning note, just like cigarettes does now? "Watch with caution, Watching might kill you, Don't watch with your children".
I don’t have a TV myself, I threw it out after I started to follow Big brother ten years ago. That was for me the lowest of the low. First I wanted to throw a party with the theme “throw the TV out of the window” but to my neighbor’s (unknowing) happiness I did not.
Scientists did a meta analysis (that is they gathered all published data from way back in 1970 up to today and put it together) and proved that watching TV will kill you by leading an earlier death.
I wonder if you add it all up, the computerized workplace, the commuting by cars and trains, will the TV stand out as the sole “killer”. Computers do play a bigger role today in our everyday lives. Perhaps these new computer games with movement sensors and such will change this.
The Disposable heroes of hiphoprisy raps; TV the drug of the nation.
This is from the paper;
“8 studies included, 4 reported results on type 2 diabetes (175 938 individuals; 6428 incident cases during 1.1 million person-years of follow-up), 4 reported on fatal or nonfatal cardiovascular disease (34 253 individuals; 1052 incident cases), and 3 reported on all-cause mortality (26 509 individuals; 1879 deaths during 202 353 person-years of follow-up). The pooled relative risks per 2 hours of TV viewing per day were 1.20 (95% CI, 1.14-1.27) for type 2 diabetes, 1.15 (95% CI, 1.06-1.23) for fatal or nonfatal cardiovascular disease, and 1.13 (95% CI, 1.07-1.18) for all-cause mortality. While the associations between time spent viewing TV and risk of type 2 diabetes and cardiovascular disease were linear, the risk of all-cause mortality appeared to increase with TV viewing duration of greater than 3 hours per day. The estimated absolute risk differences per every 2 hours of TV viewing per day were 176 cases of type 2 diabetes per 100 000 individuals per year, 38 cases of fatal cardiovascular disease per 100 000 individuals per year, and 104 deaths for all-cause mortality per 100 000 individuals per year.”

In a scene in X-men 2, a mother exclaim “this is all my fault” when discovering that her son is a mutant. The reply is “Actually , they discovered that it is the male that carries the mutant gene, so it is his fault”, refering to the father.
What is a mutation and what is genetic variation? I am myself a bit bewildered at this point, as scientists seem to use the word freely. Is mutation bad? Could be both. A buddist answer is that nothing is good or bad, it is what it is. The current environment decides what fits and does not fit.

Scientists agreeing that global warming is caused mostly by human activities:
Percentage of climate scientists agreeing: 97.4
Percentage of meteorologists agreeing: 64
Percentage of economic geologists agreeing: 47
Americans in general answer the question; estimate the no of climate scientists that claim that global warming is caused mostly by human activities;
81 to 100 % climate scientists claim etc — 15 % (of Americans)
61 to 80 % — 18 %
41 to 60 % — 18 %
21 to 40 % — 12 %
0 to 20 % — 7 %
Don’t know enough to say — 32 %
Somehow this would be an example where information has failed to come through?

The first AIDS case was reported 30 years ago. I was seven years old. I did not hear about the disease until three-four years later.
In 1987, my school was contacted by the arty Swedish Film director Roy Andersson. He had been hired by the Swedish state to make an information film about HIV and AIDS. A suprising choice
He wanted to show what the future might look like if we continued the path of fear. Fear of the virus, fear of sex, fear of being vunerable in the face of disease. So he created a dark school scene where young girls were taught have to use a condom under teacher's "it is all natural, dont you dare think anything else" supervision.
The scene is hilarious. Remember that we were twelve, it took hours before we stoped laughing and they could actually do the shooting. Luckily Roy's vision is wrong. We are not that afraid as he visioned us to be. The dark futuristic condom school scene starts at 1.56 and ends at 3.17 approx. I am in the back second row from the right.

Astronomers call this light polution and countries are starting to take action against it.
In march 2001 there was a major power break in California, frighten people called the authorites wondering about all the light spots in the sky. That is how foreign some of us have become to something that was very present in the lifes of our grandparents and the ancestral line of humans. The stars had a major part in mythology, religion, travelling and agriculture-by helping humans to keep in track with the seasons.
|Light pollution on our planet|
There are now ongoing discussions on creating "dark parks" on earth. Nature need to be preserved under goverment protection, the night sky might need it too.

Data shows that stars that have a planet in circulation probably has others. This came as a suprise to the scientists, not only that so many stars have more than one planet, but that they could be meassured, as not all planets in our solarsystem move along the same plane.
The telescope is called Keppler and has identified 116 stars with planets since its launch two years ago. The data shows 45 stars with three planets , eight stars with four planets, one star with five planets, and one star with six planets.
The telescopes scans the light from several stars at the same time. When a body passes between the star and the telescope, the light from the star is weaker. This dip correlate to the size of the object that has passed and the time is eqvivalent to the passing of the object. Thus researchers can calculate the size of the planet.
Also planets come in all sizes, Jupiters, Saturns and earths.
