Obstacle to discovery: Illusion of knowing

The illusion of knowing is the major obstacle to discovery; (October 4, 2009)
Even a century ago, a scientist would publish a single manuscript after a life time of research and toiling.
Transmission of opinions and suggestions among scientists were sent via long erudite letters by peers.
Translators of these remarkable books didn’t go unnoticed as today, but they were rewarded academically. Nowadays, any “respectable” scientist works for several institutions, private and public, and at various nations.
Even two centuries ago, scientists did not need to refer to Pythagoras or Archimedes. Modern scientists have no time or need to refer to more recent scientists such as Copernicus, Galileo, Newton, Laplace, Lavoisier, or Kelvin. Soon Einstein and Heisenberg will be outmoded.
The team of the geeks in “Sciences and Future” met in August for brainstorming in “pause mode” to deliberate on the unique question confronting the team:
“In the last few decades, what discoveries were true breakthroughs?” The team reached an understanding on 5 scientific fields: climatology, neuroscience, astronomy, cellular biology, and Internet.
Consequently, I will answer a few of the questions that you might think you know in these fields so that our knowledge is no longer an illusion.
The internet shifts from the virtual to the real
There are 3 generations of internet or Web.
The first generation or Web1.0 was created from 2003 to 2005 and is represented by MySpace, Facebook, and YouTube that gathers people on common interest social aspects or making “friends”.
The second generation or Web 2.0 is represented by Twitter or the microblogging platform for messages restricted to 140 characters. Thus, these micro messages can be regrouped and analyze to constitute a story contributed by many Twitter bloggers.
The third generation of Web 3.0 is ready technologically; this generation is already labeled object oriented intelligence sources. For example, you record a message on your cell phone and then stick a yellow sticker on a wall or an object. The next visitor will pass his cell phone over the sticker and copy your message of whatever you have seen or appreciated. This generation can zip all kinds of products and gather intelligence and compare with other resources.
Personally, I think that even the Twitter is already a perfect source of information by intelligence agencies; these centers can hire thousands of Twitter users and direct them on specific topic of interests in many countries.
Cells can be rejuvenated to its embryo stage
The lab technician would take samples of your skin. The skin cells can be treated to reach its first born state.
Whatever genetic diseases that cell inherited it will take another 30 years for the disease to emerge. All the while you are thirty years younger. Better, skin cells can be treated to isolate a specific cell for any body member like liver, heart, brain, or whatever.
The sick tissue in any part of your body can be rejuvenated within a month. This biomedical technique of treating adult cells into embryo state was made possible because many laws prohibited using fetus embryo on the ground that the cell belonged to another person.
Is man’s activity altering nature more than geophysics?
Man feared the return of the ice age; it turned out that the climate is getting hotter and the poles are melting.
The emergence of urban and industrial societies as a geophysical force is altering the environment power for rejuvenation according to human threshold for survival.
Since 1824, Joseph Fourier theorized that gases in the atmosphere have the potential to increase surface temperature.
Even in 1896, John Tyndall predicted that the concentration of CO2 will increase temperature to 5 degrees by the end of the 20th century. Now, this is a fact and each year the casualties in man and nature are increasing by the violence of climatic changes. People are waiting anxiously the international summit on the environment in Copenhagen this December.
Awareness of man effective participation in climatic changes was proven when the ozone layer of O3 in the stratosphere was depleting. Seas level is increasing 3 mm a year since 1993. So far, only Danemark produces the fourth of its power using eoliens or wind turbines.
Ex-President Bush Junior said in 1992: “The American way of life is not negotiable.”
The philosopher Michelle Serres said in 1990: “This world that we treated as an object is returning as a subject; capable of vengeance.”
The humorist Coluche said: “For an ecologist to be elected as President, trees should be allowed to vote.”
The brain is in perpetual re-structuring
There are specialized neurons that can be activated when an action is executed or when an action is also observed (mirror neurons). These mirror neurons are the biological basis for empathy, imitation, and training; almost every decision is influenced by our emotions.
Neurons have the potential to flow or transfer from one brain to another when recycling cognitive aptitudes such as reading and writing are elevated. Neurons and connections are modified when training tasks are memorized.
We have 8 varieties of intelligence; mainly the visual, spatial, naturalist, logic-mathematics, corporal, musical, inter-personal, and intra-personal intelligences.
The new battery of experiments for testing cognitive and movements capabilities are designed to account for our eight kinds of intelligences. It is the quantity of synapses (connections) and not the weight of the brain that differentiate among the various intelligences.
There are phases in our sleep when brain activities are most intense while muscular activities are extremely inhibited; this phase is called “paradox sleep”. We produce new neurons at every stage of growth, especially in the hippocampus and the smell brains.
Almost 10% of our synapses are established when we are born and they increase with our activities and cognitive demands (efforts, mental and physical, mean increase in fresh synapses and neurons).
Hormones or chemical messengers for the brains
Serotonin is a chemical messenger to the brains; it is implicated in sleep, feeding and sexual habits. A decrease in its production is associated to depressive moods. Anti-depressant drugs increase the concentration of serotonin in the blood.
Dopamine is a chemical hormone that controls movements, moods, addiction, and the circuit of pleasure; its deficiency generates rigidity in the muscles which is the symptoms of Parkinson disease.
Adrenaline is a chemical hormone that is secreted at moments of stress and is attached on large numbers of receptors to re-enforce cardiac functions, accelerate the heart beats, elevate arterial pressure, inhibit digestion and increase the level of glycemy.
Cortisol is secreted in moments of stress to increase the rate of glucose in the blood stream and liberating energy to counter dangers.
Insulin enhances the stock of glucose in the tissues and thus decreases glycemy.
Acetylcholine is a neuro-transmitter that excites the targeted brain when acquiring new training and for enhancing memory; its deficiency is the origin of Alzheimer disease.
Erythropoietin stimulates the synthesis of red blood cells; its deficiency results in anemia. The word “doping” is related to sport competitors abusing of this hormone.
