Published in 1908 a book that was translated from German continues to be a relevant and updated discourse on the ethical questions of today. Friedrich Paulsen’s “A System of Ethics” (Scribner’s Sons Pub.) was written for the general public in a plain and direct language that enlightens and analyzes topics that were of paramount importance then and still are now. As I am reading these ideas that were thought and expressed more than one hundred years ago I become aware of the transcendence of these basic virtues and values.
Today as one start a new year (for posterity: one is talking about 2006) the same old questions are asked. But for the old question there is a new perspective. One that is not really new, but for a personal renovation can be stated as a new point of view. As when one thinks about a new year in the sense of renovation, knowing that the cycle is part of a continuum, that psychologically there is a renewal as after the hibernation of winter comes the awakening of spring.
So as we wish to all a “Prosperous and Happy New Year”, the wishes are for this next year as for all the next years. Disconnected time is being connected.

Prof. Michio Kaku from City University of New York has written a wonderful account of Albert Einstein’s struggle to find the unified theory of the universe. This account goes far beyond the traditional biographies that of this great scientist have been written. For almost two hundred and fifty pages Prof. Kaku gives us an idea of the times, friends and colleagues of Albert Einstein and the way in which his thought were developed and shaped by his personal relationships. All of this is done within a profound understanding of the physics involved so this is not only a historical description of the life of a great mind, but it also enlightens one with the intricacies of the theoretical concepts in modern physics and the relationship of these concepts with natural philosophy and ultimately to our final sense of reality.

I don't know if it is too late to argue about our counting (measuring) of time but one thing I know: it is the semantic knowledge through our language (or the lack of it) that leads us to the understanding(or to problems) of dating. Here is an easy way out: If I have been teaching (i.e. I am still doing it) since a particular date, I can count how many years have passed (X) and I can say that I am in my Yth year. Where Y = X + 1. In this sense the year 2000 is in fact the 2001st year as 2000 years have passed.

It is difficult to appreciate the full scope of time when one is limited to a short time experience. As our definition of time and the units that we use for its measurement are so anthropocentric it is almost impossible to make any lucubration about universal time. As Einstein proposed his basic assumptions about the universe he made one powerful move: there is unity of the universe. By stating two fundamental principles, one philosophic and one physical, the theory of relativity is able to conform the cosmos to a “continuum” where a vacuum filled with “fields” manifest itself as matter or energy depending on the configuration of the geometry of that space. It may be that because of this Einstein expressed his opinion that geometry was a “physical” science. The philosophical principle is that the laws of physics are the same for any observer. So if two observers were moving relative to each other and they observed the same phenomenon they should get to the same law as the explanation of said phenomenon. On the one hand the constancy of the speed of light in vacuum as electromagnetic radiation being the physical principle allows the connection between those observers that are moving relative to each other. Can we use the same bridge –the constancy of the speed of light – to connect our time to “cosmic” time? With string theory the effort is to connect our time to the atto –femto scale by means of quantum field theory. As far as I know this has been attempted through gravitational field theory (quantum and relativistic) but the assumption has been that if the time involved in the phenomenon is grater than that of Planck’s time (1.38 E-43 sec.) time will be considered continuous that is as an analog function where its flow is directed by the second law of thermodynamics

One reason that cosmological studies are so important can be seen in this blog's question(http://abandontheweb.blogspot.com/) " Is hi-tech timeless? one can see that it is!
Loyal starts a comment with: "In technology...More is law. More speed, more storage, more graphics, and so on." But will this law—more of an assumption, really—be true tomorrow, and is it true today?

What should students be studying in college? No one seems to agree anymore. Harvard University is in the midst of a heated debate about its general education requirements, while the Association of American Colleges and Universities has launched a campaign to promote "a liberal education." Slate has taken the occasion to ask an array of prominent academics to tackle the question at the heart of the debate: What should undergraduates leave college knowing?"
This is such an important and ongoing question that needs all of us in higher education to get involved. Two points I would like to make: Blogs are becoming a wonderful tool for the discussion, and the discussion is now open to a wider audience.
Cross references and recycling electrons is fairly efficient, so let's do it!

So is it the world real? Or is it an idea? (Old question that we'll not answer here!)
Along human history there have been many discoveries of “natural” laws and phenomena that occurred by serendipity, or mistake! Some discoveries were due to unsuccessful attempts to demonstrate some unsustainable theory such as the existence of aether. This aether had been proposed to explain the transmission of light and its high speed through the universe. The experiment performed by Michelson and Morley as it failed opened the door to a new way of thinking; where the idea of “vacuum” became accepted, and as others -like Lorentz try to “fix” the problem- were very imaginative with their proposals.
Lorentz proposal of a contracting space even though wrongly stated to fix the Michelson-Morley experiment gave support later on to Einstein for his proposal of “time” relativity where time itself would shrink or dilate if the observer was moving relative to the frame of reference. Lorentz contraction –or relative expansion of the other system- is now used with no hesitation as one calculates the interaction of orbiting communication satellites that use electromagnetic signals that have to follow Einstein’s relativity theory.
Time after all is relative, so I’m going to stop here

Does it mean that time doesn't exist because we aren't able to explain what time is?
Reality, Reason, and Imagination are linked through the search of truth. How can one undestand reality? Natural laws have to be universal thus objective and they have to be discovered through one's reason. It is important to realize that human reason is over all dependable even though in some cases it looks like it is not!
Common sense is commonly wrong! So one has to be careful in equating common sense to human reasoning.
All this is to establish a framework for our understanding of time or lack of it.
Yesterday Oct. 1st during the Linus Pauling Award symposium George M. Whitesides (the recipiant of the prize) lectured on some of the concepts about matter that we are in the very beggining of understanding. One of this concepts is the relationship between enthalpy and entropy, as in chemistry one normally relate them in the sense that one is at the expense of the other! This concept makes one think that one really do not know what enthalpy or entropy are about.
So if enthalpy and entropy do exist even though on doesn't know what they are, maibe time also exists even though one doesn't know waht it is!

Timing is everything in economic terms as well as in social terms, as they are intrinsically dependent. When we one look at the linking between social developments and economic ones the “energy” bridge is used to understand it. How is this link defined and affected by our definition of “energy”, and how are time and energy related is a profound philosophical question that few have tried to address. We’ll try in my book (Treatise on Physical Economy) to address this question and to propose some ideas regarding the physical nature of social development and behavior. Some of these ideas have been around for a long time, some since the XVIII century and I hope some will be brand-new as they are proposed in the light of current events.

As the title indicates this is a good introductory book to a very important subject in modern science. Bernard Schutz using a clear and direct language allows readers that are not specialists understand and most importantly enjoy the discussion of basic scientific ideas. The understanding of “Gravity” as it is related to the functioning of the universe is of paramount importance for the understanding of all natural phenomena. Schutz gives examples from astronomy to show how the universe can be used as a laboratory and how measuring distances and masses, and calculating their ratios, is used to infer laws and deduce the existence of black holes. Other astronomical objects and phenomena, such as neutron stars and cosmic rays, are mentioned as indicators of the kind of knowledge we can gather for the understanding of how the universe functions. Some one who is interested in understanding the principles of the time-space relationship and the correlation of mass and energy should read this book.

Today we face a situation if we try to reconstruct the constitution by looking at the letter of the law and forget to look for the spirit of the law.

From the inside cover: “This is the story of two Wall Street Journal beat reporters –one covering the energy industry just after the chaotic California electricity crisis; the other chasing stock swindlers. Together these journalists were ideally placed to uncover one of the great cons of the century.” If you’ll like to have a profound insight of what happened with the Enron story, how economic power goes hand in hand with political power, and how modern technology can be used to create artificially immense wealth, this is a book you’ll like to read.
It is interesting to see how time plays such an important role, timing of the con with the political atmosphere of deregulation.

Several cases in particular relate directly with Northwestern US. From “Salmon and People” presented by Mary Brentwood (Assistant Professor of Environmental Studies at California State University, Sacramento) to “Wolf Politics” by Martin Nie (Assistant Professor of Natural Resources Policy at the University of Montana.)
The format of the book is inviting and induces a discussion where both sides of the issue are recognized. Based on actual cases gives the reader a broad idea of environmental issues facing our world, as well as a perspective of the situation that comprises all sides.
Even though the cases presented are based in the USA and mention real institutions and organizations the book has not a provincial view, it can be used and read to gain a general, universal perspective.

According to Michael Tanzer: There is no energy shortage. The problem lies on the power struggle between energy companies and their host countries.
With very few exemptions this book written in 1974 is actual. Up to that date facts represent in general what is still going on. So the content becomes so relevant to today's situation where as crazy as it sounds, nothing has change in more that 30 years!
On the other hand and looking into the paradoxical nature of our use of energy, we might expect that unnoticed changes have occurred, and these will suddenly -without any warning- bring havoc in our society. Hopefully this havoc will give way to a positive chaotic transition out of which a more equilibrated and just society will emerge.
This is a short read -about 170 pages, and highly recommended.

And, as I truly like questions- finishes with the following: "22 Wherefore I perceive that there is nothing better, than a man should rejoice in his own works; for that is his portion; for who shall bring him to see what shall be after him? "
Accepting that there is a time for each thing and each thing has to be at its own time is for me so fundamental and basically the only way to achieve happiness. Having work as a means for excellence and being is a truism. Finally who knows what is after him/her? But one thing we know: we are another link of humanity. The link that comes after history and before the future thus "we are the present." Whoever we are it doesn't matter.
We are the present. Even after we die, whenever someone read this, it will be.
"2 A time to be born, and a time to die; a time to plant, and a time to pluck up that which is planted; 3 A time to kill, and a time to heal; a time to break down, and a time to build up; 4 A time to weep, and a time to laugh; a time to mourn, and a time to dance; ... "
So how can I change what I am doing here? Is it time to change? So I figured it out! Maybe if we have another blog. That way we will not deviate from the main topic-time that we are supposed to deal with here. We can also post in another language - say Spanish. So once in a while check my other blogs, you can find the by going to "view my complete profile" and clicking on the other blogs at the end of the profile.

Lewis' claim is that if you don't believe in miracles -that would be your philosophical framework- then it can't be proven that miracles exist. One must then be in the right frame of mind what ever that means!!!!

If you are interested in paradox, language, ontology or semantics this is the book for you! It looks like it is only about mathematics but it is not. Written for the general public, it doesn’t require you to be proficient in math even though formulas are used in order to clarify the semantic connection of reality with concept. In fact I recommend this reading to those who have had bad experiences with math. Penrose is one of the clearest minds alive today and his writings in Mathematical Physics directed to specialists, as well as his writings directed to the general public have become classics.

For a statistical analysis to be strong and confiable is it necessary to have a good set of information, data in sufficient quantity that allows us to see the pattern that describes the system in question. This sufficiency in the amount of information is what we call "critical mass" a term borrowed from nuclear physicist that define the critical mass of a nuclear reaction in terms of the density of radionuclides involved in the reaction. All in nature including of course human behaviour requieres a critical point from which reference is made. A city or town doesn't becomes a city or town until that critical mass is acquiered

One can see a deeper purpose in this law. Lets think of different mechanisms, some will increase the order of the system (as the total entropy of the universe increase) and others will decrease the order of the system. For example nutrition versus aging. The competition of mechanisms depends on the relationships of the energies involved with the rates at which the change is occurring. It is all about rates! So time is a basic, fundamental frame of reference.
In the realm of religion:
Our Lord Jesus Christ came two thousand years ago and we are still struggling with his teachings. Christianity has some basic principles that I see are related to the second law of thermodynamics. Love thy enemy! Is this proposition breaking some kind of order that states that we and they are different? Thus belonging to separate organized groups? If we are to love our enemies, we are not different from them under His eyes.

My own concern, my own life.
As I'm cooling down it seems to me that I'm slowing down. Temperature is the scalar measure of the heat (energy) level so as our energy level drops we slow down. Can we think of this energy level in terms of energy density and if so isn't it that energy and mass (the curvature of space according to Einstein) are related? So how are space -with its curvature- and time related? Gravity has been explained based on a warping of time/space. Where is energy in this picture?

Time for reflection.
In Spanish people ask about time when thinking about the weather, how are weather and time related?
Como está el tiempo? is: How is the weather?
Could it be that time goes faster when the weather isn't nice? Is it going to the beach and enjoying yourself an energizing experience because time is going so slow? Has this energizing effect anything to do with the energy used in the passage of time?
The only way we have to see the passage of time is when changes in energy occur. Changes could be from one kind of energy to another or changes in the level of the same kind i.e. quantitative or qualitative.

Within the framework of education we have assumed that one hour of class is one hour of teaching equivalent to one hour of learning. The hour of class makes the hour of teaching synchronous with the hour of learning.
Here is where I have some uneasiness. My feelings are that teaching and learning aren't happening at the same "time"
