"It's a simple fact that many Americans don't want to face. Workers' rights are being trampled upon abroad to keep labor and other production costs down. The price tags we see on goods from those countries may be lower, but that's because someone else has already paid dearly...Jail terms, beating, kidnappings, torture are all-too-common...these violations of basic human rights should not enable foreign nations or multi-national coorperations to prosper." ~ International Union

What is time?
It's 12:50
pm, so simple right? One can look at his/her watch or computer screen or phone
to tell what time it is. But, how did human measure time a thousand or even a
million years ago? There was no such thing as watch, phone, or computer. The
old method is using the position of the sun on the sky; a new day begins with
the sun rises and the cycle continues for what seems to be infinite relative to
our life time. Another method used by Chinese calendar was the moon. One
revolution of the moon around the Earth was one lunar month. Then, there came
the mechanical clock, then scientists used speed of light to redefine the
definition of a second, and now they are using the radioactive property of
Caesium-133 to define the nature of 1 second. However, for some people, one
second is merely greater than the time it takes to blink, thirty minutes is the
time to get to work, five minutes is the time to brush ones' teeth, and as for
me seven minutes is the time it takes to ride my bike from my dorm to my class.
As we all see, time is compared/seen as distance between home and work, the
position of one celestial body relative to another, the time its take for one
photon to go 299,792,458 meters… If one has a hard time imagining the
"fourth dimension"-time, it is, in these cases, being estimated by
the other three dimensions. Nevertheless, why can't we "see" time nor
draw a world with four dimensions.
That's because we just simply can't. For example, if we could see the
famous, extra "fourth dimension," time, as any of the three other
dimensions, we would easily look back in time and even at the future as simply
looking down the road. I personally think it is really stupid of anyone to try
to understand the computer graphic of four, ten, or twenty dimensions, we just
can't PERIOD. As I just said, it's one reason for humans to use the three
dimensions to estimate time.
So, where
does time come from? People are discussing that the Big Bang created time, but
how come? Don't we have time before the Bang? It is hard to perceive not to
have time, isn't it? But think this way. The big Bang created stuffs which in
turn created the Stars, the Sun, the Earth, the Moon, photons, Cesium... They
are our instruments to measure time, aren't they? It's the creation of 3D space
that makes it possible to estimate time. Not fully persuaded/understood? Put it
this way, I am about to prove time backward. Assume that the Big Rip is true
(The Big Rip is a cosmological hypothesis first published in 2003, about the
ultimate fate of the universe, in which the matter of the universe, from stars
and galaxies to atoms and subatomic particles, is progressively torn apart by
the expansion of the universe at a certain time in the future). So particles
(photons, quarks...) will be infinitely away from each other. In other word, no
two particles will ever meet again. So, a photon (light particle) will be alone
in the universe, and it won't know that it is traveling at 300 million meters
per second because there is nothing around it (such as houses, planets, or
stars) to tell how far it goes. Or this photon is being confused by asking
"am I really moving? I don't see so." The 3D space is annihilated
into 0D space-a single point, and frankly time has disappeared because there is
no photon can tell the time or Cesium to decay. So the "rip"
of matter brings the disappearance of time. Now, we go back and say, the
creation of matter, the Big Bang, creates time.
What was the invention creating this civilization?

Who decides the ethics of bio engineering?
Continuing with the ethics of biotech, and the blaming game on the government (Everyone keeps pointing at the government telling that they should regulate bio technology to make things right and ethical). Well, they should. But, big coorperations are having more influence on politics now. They have money to fund elections, hire lobbyists, "buy" lawmakers, have their own lawyers (we all know what lawyers do!!!), and many other things.

You can't trust the government anymore, so who else to make it right?!?!?!?!

Technology and humanity
Johnson argues for Social Construction of Technology (SCOT) in which technologies are shaped by society, and at the same time, technologies can have their influence back on what creates/shapes them. She successfully disproved the major tenet of Technological Determinism, technology is seen as an isolated object developing independently from the society, by giving examples about the socially constructed bicycle (Johnson, 2005, p. 1793), and the production and distribution of nuclear power from Winner (1986). Johnson (2005) stated that “Scientists and engineers look at nature through lenses of human interests, theories, and concepts; engineers invent and build things that fit into particular social and cultural contexts” (p. 1792). Social factors can shape or thrust technological development in a certain direction. Studies of Anderson et al (2010) about engineering further confirms the intertwinement between society (e.g. economy, politics) and technology. He found out that in order for an engineer to invent or redesign certain technology, he has to communicate with his client or clients to understand what they want, cooperate with his team/company to see what resources are available, finish the job within the budget and time, and more importantly his product has to follow the engineering standards and government regulations. Therefore, technology is "social." Johnson (2009) suggested “[Users can] shape the technology by customizing settings, demanding changes from developers, and choosing between alternative products” (p. 15). An example for this social constructivism viewpoint is when users decide to buy/use a certain branch of cell phone (iPhone for example), the money gained from the business can be used to further develop the iPhone according to customers’ needs or Apple’s ambitions, but on the other hand, less popular types of cellphones quietly go out of business. Technological determinists, individuals believe that technologies develop by themselves, and new technologies evolves from older ones, have their invaluable points on this user-related situation. Ceruzzi (2005) pointed out that some people could deny buying computers, but the growing power of the computer chip was “unstoppable”. Especially, some technologies such as digital camera and Microsoft Word left users with no choice but to accept it (p. 586).
The living examples for the rampant influence of computing technologies are that each engineering student at the University of Virginia is “required” to have a laptop or tablet, and to have their research papers word processed. Again, SCOT comes into play in this situation. Depending on what kind of laptop or tablet they buy, they inadvertently push the development of the computer in a particular direction. What about the people who never buy or use a computer? Do they have any influence on computing technology? Business people are more likely to say “No” because there is no point in developing computer based on the interests of these people, who will not spend any money on computing products. It is not just in the computing industry that certain groups of people have no power in “shaping” technology, but also other fields of technology such as automobiles and housing. The poor and the homeless have little or no influence on these technologies because businesses or private companies always aim for the people with the money, not the penniless ones. They only design cars and houses to fit the needs of their customers. As engineers develop more advanced technologies, they have also “[enforced] social biases and privilege individual agendas” (Johnson, 2009, p. 17) because little voice of the “powerless” is taken into consideration. Reasoning about social biases, the powerful and the rich people, where did they get the money from? Jarmo (1999) offered a brilliant example on how people can get rich by harming the environment, and suppressing others’ opportunities to survive. For the negative effect of the economy (e.g. forest industry) on the environment Jarmo (1999) pointed out that “… the whole river smells of timber, waterlogged softwood. It is unbelievable how many logs are in the water, floating along with the stream” (p. 238). Big companies built sawmills to make lots of money, and meanwhile they rapidly wiping away the water and food supplies of many other people. Jarmo (1999) further noted how the river was mistreated saying “[The river was] a means of disposing waste. The forest industry has utilized lake and river systems as sewers, and it has been the worst water polluter in Finland” (as cited in Tana & Lehtinen, 1996). Luckily, we do not see these scenes in Finland, today (Jarmo, 1999, p. 238). However, until the environmental regulations came into play, business people in forest industry had earned a large amount of money which they could use to earn even more money (e.g. creating more troubles, and social biases), while the poorer people, who lived on the river resources such as fish and games, were affected by the environmental change struggling to for a living. This poor, powerless group of people had no voice in determining how the powerful ones use technology to change or even “determine” their lives. In this case, Technological Determinism unmasks its authority.
However, there came the government regulations on these polluting companies to protect the environment. Technology (e.g. forest industry) is now shifted to the side of social construction (e.g. being shaped by politics), but what has been done to compensate for the harm to the environment, and the hard time of fishermen and their families, whose lives depended on the health of the river? “Nothing,” but somewhat, the “polluting villain” was restrained. The rich flee with their bags full of money. Where is justice? “Aren’t all men created equal?”
“Yes, they are,” but some men take advantage of the natural and social recourses faster, and more viciously than the others do. Their acts negatively disturb the latecomers’ development promoting social inequality. Is technology the root of all these troubling, social injustice? It is complicated, but for some instances technology does push society in certain ways which promote the social injustice. Winner (1986) gave an example about the tomato harvester which was developed by tax money, but it was used to benefit certain group of people while severely “punish” the others (p. 7), engineers get the jobs about the tomato harvesters while works for most former farmers silently disappear. Nye (2006) stated that internet was military funded (p. 10). However, who is benefiting from this technology? Is it Google or Yahoo or Amazon or everyone? “Everyone benefits from the internet,” of course not, but if it is even so, who gains the most?
Winner (1986) pointed out the development of certain bridges on Long Island as a determinant for the social inequality:
Some two hundred or so low-hanging overpasses on Long Island were there for a reason [that]…poor people and blacks, who normally used public transit, were kept off the roads because the twelve-foot tall buses could not handle the over passes (p. 3-4).
Furthermore, the design of roads in the United States in most places also determines how certain technology can be adopted, while also making it impractical for others. For example, most roads and especially highways do not have bicycle lanes. For this reason, people tend to use automobiles rather than bicycles as their transportation. For the young and poor people, they have no car, and also have no choice; they use car lanes for cycling and skateboarding; this inadvertently increases the likeliness of them getting killed. The outcomes of the tomato harvester, the internet, the Long Island bridges, and road design reveal to us that certain technologies can promote if not “determine” the social injustice. Are the Amish, Christians aiming for a humble life, protecting social justice by denying modern technologies?
Wetmore (2007) emphasized that, “[The Amish] believe change does not necessarily result in desirable ends” (p. 297). They prohibit whichever technology disrupts the harmony of their community. Amish people long for a united community with peace, love and equality (Wetmore, 2007). Are these values, peace, love and equality, the ultimate answer for “progress to what?” in Marx’s (2000, p. 12) Does improved technology mean progress?, and the reason for “Benjamin Franklin’s refusal to exploit his inventions for private profit” (p. 6), and also the statement Thomas Jefferson craved to make in the Declaration of Independence? The answer is “Absolutely yes” because if it is “no,” what are we pursuing? Or we may further ask “Why are we here? What is the meaning of life?” The Amish have the answer from the beginning, peace, love and equality. So, at the end of the journey, are the Amish somehow more advanced (e.g. closer to the ultimate goals of life) than anyone else of the “human race.” Or are they? In the talk of Tarter (2009, personal communication) at TED Prize Wish, she mentioned about the possibility of another intelligent life on Earth if not somewhere million or billions lightyears away. It was the dolphins. Possibly, they are the ones who are more socially advanced than humans. Even though they don’t have powerful technologies or complicated laws for science, mathematics and politics, they are the ones living in joy, peace and equality. They look at us, and wonder why we had to bother with all the troubles for education, technologies, wars, politics… while they can do the same thing (e.g. living happily) or even better with less effort, and perhaps the Amish people also look at us with the same wonder. With this conception about life, we can somewhat pinpoint what we want from this world or technologies that when we do something (e.g. develop new technologies or even buying a water bottle) we will not get off the track to our desirable ends.

Future of humans' physical traits
Source: http://www.gorillatours.co.ug/tours/ uganda-chimpanzee-trekking-tours.html |
There's another trait that I want to point out that is it true that our noses are getting bigger because of the polluted air? Well, our noses are relatively bigger than chimpanzees for the fact, and with the increase of dust in the air, the human body definitely need a more sophisticated respiratory system to filter the pollutants. One of the solutions is a big nose with lots of hair. Eww!!! Yes, I know but that's the direction human is "racing" to.

Dragon: a legendary creature or a evolutionary possibility
Have you ever been to a circuit to see magician breathing fire? Or at least saw those tricks on TV? Dragon or perhaps any kind of creature might have possess the ability to breathe fire with the same mechanism as magicians, except dragon didn't need external fuel for its trick. Just look at human body for instant, we can involuntarily produce methane (CH4), a highly flammable gas, through our digestive systems. Why not dragon? Ever saw AFV (American funniest video)? There was a fat man farted into a small flame, and got his gas ignited burning his friend. With fire-breathing ability, dragon could have use them for hunting, defending, or even warming. So there was a high chance that dragon might evolve just to do that. All dragon needed was a spark to ignite methane gas or any flammable gas they possibly produced. A biologist, may argue that how can animal make fire while ancient humans discovered fire not so long ago? As I previously stated, all dragon needed was a spark, it could be an electrical spark! Again, physicists may disapprove even more strongly than biologists because Maxwell united the electric force and magnetic force just more than a century ago, and the existence or use of electricity didn't reach its technological momentum until 20th century. Have you ever heard of electric eels? Yeah. That's the answer! Some animals can produce electricity by themselves. Several years ago, I had the opportunity to see Christmas lights flashing different colors by the electrical energy produced by electric eel on TV. It was an idea originated from Japan, but I didn't have chance to do more research on this. So, what's the point? As we see, nature/animal can produce methane and electricity. The right combination of this two conditions with certainly create a fire breathing creature which we call dragon. Why dragon didn't get kill by its hot fire? The fire didn't come from the stomach of the dragon or any where inside its body, but the fuel which was methane was breathed out through the dragon's front doors (which was opposite to the fat man in AFV using his backdoor). Therefore, it's reasonable to deduce that the electric spark was ignited at the every end of these methane doors.
What's about the other things? Like flying, and poisonous part of dragon?
Flying can be seen in animals, birds for instance, but it doesn't stop there. The history of celestial monsters dates back to hundreds millions years ago, when dinosaurs still rampant the earth. Dragons might have been flying side by side with Pterosaurs and even hunting these poor dinosaurs with their fires. What's about the poison part of dragon? Most snakes have poisons, even some frogs, spiders… have poisons. So there's nothing unimaginable about poisonous dragon.
There's one more question from many specialists and laymen which is "where's the dragon?" I don't know. It may be extinct along with dinosaurs many millions years before early humans came to being. So where's the skeleton. Yeah, about that. Archaeologist may have found many of them, but they still want to call those "dinosaurs". With our current technology, we can't tell if dinosaur (or maybe dragon) have specific organs or systems to breath fire. Scientists can only tell the functions of specific bone structures (since bones were all left after millions years), but they can't pinpoint a stomach like chamber which kept the methane gas. That's because this chamber would have certainly decayed or transmuted into something totally different from its original form if the chamber had ever existed. So in the course of our technological development, we can hope that one day we can unravel the existence of dragons or may call them back to being thanks to our bio engineers. With the simple mechanism of methane gas and electrostatic spark, dragon is no more a legendary creature than an evolutionarily possible animal.
