The fool who wrote this piece
Would wonder if he did miss
The essence of its message
Or time in its passage.

The trees are gone with the cloud, 
Laying a desert on its path,
While the winds applaud
An evil aftermath.

I think I shall finally see
A kind-hearted man plant a tree,
For he who truly loves Thee,
Shall love others through a tree. ~

More than your name,
You are my father's home,
And his resting ground;
Link of darkness and light;
Window to the universe, 
Source of song and verse,
Treasured niche in space,
The cradle of my race. ~

Bullcart

Bullcart
Dr Abe V Rotor

Author's children, Ann and Matt pose in an empty bullcart 
near their ancestral home, San Vicente, Ilocos Sur, circa 1992. 

They wait for the buffalo
that pulls the cart
as I search the fields,
cross the rivers,
gaze over the hill,
onto the prairies of old,
repeating the call
that reverberates
over the plains
where a great
civilization perished.

What will I tell my children
now that the buffaloes are gone?
In time they'll understand. ~

The Dilemma of Ecology - All in the Name of Progress

Lesson on TATAKalikasan, Ateneo de Manila University
87.9 FM Radyo Katipunan, every Thursday) 11 to 12 a.m.
The Dilemma of Ecology
- All in the Name of Progress
Dr. Abe V. Rotor
Co-host with Prof Emoy Rodolfo

Death of an Ecosystem

• It looks like man has been able to trace the source of the water that comes from the proverbial Pierian Spring, the secret of health and long life. For years it was believed that the spring lies up in Shangri-La atop the Himalayas, or according to the Greeks on Mt. Olympus, or the Egyptians in the Pyramids. One does not have to go there now. Even today  the average life span of man is mid 70. It will not be a surprise if one out of a hundred individuals will be a centenarian. One report claims that the life span of man can be increased to 140 years by the middle of the millennium. How long did Moses live?

• But cancer is on the rise, so with AIDS, and the spread of genetically linked defects and illness. Work-related and stress-related deaths will likewise increase with heart and severe depression as the leading diseases, followed by the traditional diseases like respiratory and diarrhea diseases. Already there are 15 million who have died of AIDS and 40 million more who are living with HIV, the viral infection. A pandemic potential with up to 1 billion people to become affected with HIV has started appearing on some crystal balls and this is not impossible if it hits populous Asia.

• Cloning, the most controversial discovery in biology and medicine will continue to steal the limelight in this millennium, stirring conscience, ethics and religion. It is now sensed as the biggest threat to human society, and if Frankenstein is back and some people regard him as a hero instead of a villain, we can only imagine the imminent destruction our society faces - the emergence of sub- and ultra- human beings. On the other hand, there are those who look at cloning as an important tool of medicine to enable doctors to save lives and increase life expectancy. They also believe that cloning in situ (on site) will do away with tedious and unreliable organ transplants.

• Gene therapy is in, medicinal healing is out. It means diagnosing the potential disease before it strikes by knowing its source. Actually diseases are triggered by specific genes. Reading the gene map of an individual, the doctor can “cure” the disease right at it genetic source. We call this gene therapy, the newest field in medical science. But the altered gene will be passed on to the next generation. Playing God, isn’t? Definitely it is, and it is possible to use this technology not only for the sake of treatment but for programmed genetic alteration. Another Frankenstein in the offing? But scientists are saying gene therapy can be a tool in removing permanently the genes that cause cancer, AIDS, and genetically linked diseases like diabetes, Down ’s syndrome, and probably alcoholism.

• We are in an age of test tube babies. There are now more than 100,000 test tube babies in the US alone since 1978, the arrival of Louise Brown, the world’s first test tube baby. The industry has just started booming with sperm and ova banks established and linked with the Internet and other commodity channels. Not only childless couples can have children, but even a sixty year old woman can - through what is coined as menopausal childbirth technology. Surrogate mothers for hire, anyone?

• If diseases can be predicted and successfully treated, and life can be prolonged – these have indeed grave consequences to population increase. Already there are 6.7 billion people inhabiting the earth today, and we are increasing at the rate of more than 80 million a year. After 2150 we shall have reached 13 billion, the estimated maximum capacity our planet can support. Is the Malthusian theory true after all? It looks like the ghost of this English political economist and religious leader, the founder of this theory, is back to warn us, this time more urgent than his 1789 prediction that as population grows and that food production grows only mathematically, there will come a time when population will outstrip the capacity of the earth to feed the world’s population resulting to famine.

• Our Earth is getting warmer, and this is not any kind of comfort but destruction. We have experienced seven of the ten warmest years in the past decade and we are heading toward another Noah’s episode. Low lying areas where the rich farmlands and many big cities virtually squat will be flooded. Heat is trapped by the carbon that we generate from our cars and industries creating a “greenhouse effect”. As the world’s temperature increases, the polar ice melts, and more rains and climatic disturbances ensue. Climate scientists have predicted that by year 2100 the earth’s temperature will go up from 1 to 3.5 degrees centigrade. But wait, the worst is yet to come. Global warming will plunge us ultimately – towards the middle of the millennium – into another ice age! There will be a buildup of ice at the Polar Regions as the ocean currents fail to carry warm water to the poles and back.

• The trend of lifestyle will be toward the simple and natural, even in the midst of high-tech living. More and more people will go for natural food and natural medicine as they become conscious of their health. The media and the information highway will provide more people access to entertainment and information. Remote management and distance learning will greatly influence business and education. But people will still seek greener pastures in cities and in foreign lands.

• “Save the earth!” has yet to be a denominator of cooperation and peace among nations. The failure of the Earth Summit at Rio de Janeiro, and the first summit before in Stockholm, has produced valuable lessons leaders must learn. There is only one ship in which all of us are riding. Let us all save our ship.

All in the name of Progress
It is all in the name of progress that nations are pursuing. The West insists of pushing the frontiers of technology into the so-called “third wave”. The East, the Asian Pacific region, insists on industrialization in order to catch up with the progress of the West, while the Middle East has yet to undergo a major socio-cultural and political transformation while aiming at lofty economic goals.

Ruins of the famed Hanging Gardens of Babylon during the time of Nebuchadnezzar 

Progress, it is generally believed, is the aim of globalization, and globalization is building of a world village. Isn’t this the key to peace and cooperation? This sounds familiar to scholars and leaders.

Maybe, but the greatest challenge lies in the preservation of a healthy Mother Earth, a common denominator of concern irrespective of political, ideological and religious boundaries. It is the saving of the environment that will be the biggest challenge to this and the coming generations.

Poor Rating of Earth Summits

Let us look at what happened to the promises made by leaders from 178 nations who gathered in the Earth Summit in Rio de Janeiro more than a decade ago. These are the four areas of accord: biodiversity, climate, deforestation, and population.

On the biodiversity accord signed by 161 countries (except the US), ecosystems continue to be assaulted and fragmented. On arresting global warming as a result of emissions from industries and vehicles, developing countries on the path of industrialization have exacerbated the problem. Deforestation virtually knows no limits and bounds as long as there is wilderness to conquer. Every year forests are lost the size of Nepal. Asia has lost 95 percent of its woodlands.

Every year about 80 millions people are added. Although birth rates are going down in the West as well as in the NICS, there is a boom in babies in rural Asia Latin America and Africa.

Rhetoric and promises can not be relied upon. It is in this area that globalization should be reviewed. Globalization should be defined in economic, cultural and environmental terms. This triad approach has yet to be addressed to all members of the global village. And there should be a new world governance, more credible than the UN, to undertake this gargantuan task. Kyoto Protocol on Greenhouse Gases. On December 10, 1997, 160 nations reached agreement in Kyoto, Japan, to limit emission of CO2 and other gases in order to arrest Greenhouse Effect threatening the whole world. But not all countries signed the treaty, among them the US and Australia. Actually the Kyoto Protocol is not new. In 1992, some 170 countries ratified a similar treaty reducing emission of gases to the level of 1990 by 2000, but this did not yield the desired result.

“Hundreds of millions of people will starve to death,” warned Paul Ehrlich in his 1968 book, “The Population Bomb.” This is an echo of the Malthusian Theory raised 200 years ago. This means farmers, in spite of biotechnology, can not keep up indefinitely with increasing food demands. Yet there is a great disparity in food distribution. While the average adult needs 2200 calories a day, an American consumes 3603 as compared to the intake of a Kenyan which is only 1991 calories.

Ecomigration

Degradation of the land, the breaking up of ecosystems, are resulting to modern day exodus of ecomigrants who cross borders, invade cities and build marginal communities, threaten security of nations, and creates other socio-economic problems. Desertification, soil erosion, overuse of farms drive multitudes to search for greener pasture, many in the guise of overseas workers, settlers, refugees.

The birth of mega cities is a human phenomenon in modern times. The world’s cities are bursting at the seams. Half of the world’s population live in urban areas today, and more are coming in. In developed countries 75 percent of their population lives in cities. By year 2015, 27 of the world’s 33 largest cities will be found in Asia, with Bombay and Shanghai bursting with 20 million each. Today the most populous city in the world is Tokyo with 27 million people. New York has 16.3 millions which is about the same as Sao Paolo. Metro Manila has 10 million.

On global warming, figures show how the world fares under greenhouse effect. This phenomenon is attributed to the severity of the last three episodes of El Nino in the last three decades, and to the prevalence of deadly tornadoes, hurricane, floods and natural calamities.

A hole in the sky was caused by damaging chemicals that tear down the vital atmospheric ozone shield that keeps us from too much heat and radiation. The size of the ozone hole about the Antarctic region is estimated to be like the whole continental US – and is still expanding. CFC use is now restricted in most countries, but there are other damaging chemicals used by agriculture and industry. Methyl bromide for one is 40 times more destructive to ozone than CFC.

Antarctica: World’s Park
One of the few places on earth unexploited by humans is Antarctica. Not now, not until recently. With the Antarctic Treaty of 1991 declares that “Antarctica shall be open to all nations to conduct scientific or other peaceful activities there,” seven countries have already laid overlapping claims on the continent, which comprises one-tenth of the world’s total land area. Thousands of tourists are now visiting Antarctica every year.

Scientific research is economically motivated, such as oil exploration, with geopolitical or military objectives in mind. Earlier – in the 1970s New Zealand proposed designating an Antarctica World Park, making it an international wilderness area. On the ecological point of view, Antarctica is fragile with simple and short food chains that support few organisms such as the penguin, whales, shrimp-like krill. Any slight disturbance is likely to upset the delicate balance. We have already caused the growing hole of the ozone layer above Antarctica through unabated release of CFCs , and fossil-fuel combustion worldwide. Would humanity be better served by developing the natural resources of Antarctica than turning it into a world park and preserve its ecological balance?

We also ask the same question to areas similar to Antarctica, such as the pristine wildlife of Canada, Greenland, the Yukon Territories, the unexplored islands of the Pacific, and main Amazon Basin.

Ecology and Stock Exchange

In 2000, Earth Sanctuaries was listed on the Australian Stock Exchange, making it the world’s first conservation company to go public. We know that conservation efforts have been conventionally under foundations and government projects. But this times this intriguing approach to conserving the environment raised as lot of questions.

Does the market place really have a role in habitat preservation? Is this approach really conserving natural ecosystem or just creating large zoos? Would we rather save and give our children good education that helps rescue an endangered animal? Indeed the conflict between maximizing profits and conservation raises ethical issues.

Ecology advertising

In the supermarket we find tags, organically grown, environment-friendly, eco-safe, environmentally safe, children-safe, ozone-friend, and so on. But are these claims true?

Consider the following:
• Look for the three-phase symbol of recycling – three interacting arrows to form a triangle.
• When buying a refrigerator or air-conditioned get the one that is Freon-free, ozone friendly. Be sure the purchase is covered by company guarantee.
• Producers of food claimed to be safe, such as organically grown, must be able to show a reliable track record. It is good to trace the source of food that we eat, from beginning with production to processing, and ultimately to the dining table.
• Even materials claimed to be biodegradable, photo-degradable, and the like, may not be readily converted into safe materials. As a general rule, save money from “over-packaged” commodities, and you save the environment as well. Don’t be misled by package advertising, how attractive it may appear.

Business versus Environment

Is it possible to have a healthy environment and a healthy economy at the same time? More and more businesses have begun adopting this concept as a business philosophy. People behind business organizations are becoming more aware of the ethical decisions they face, and their responsibility for their consequences. A multi-national corporation, responding to the provisions of GRI (Global Reporting Initiative), CERES (Coalition of Environmental Responsible Economies), UNEP (United Nations Environmental Program), came up with the following thrusts:

• Restore and preserve the environment
• Reduce waste and pollution
• Education of the public on environmental conservation
• Work with government for sound and responsible environmental program
• Assess impact of business on the environment and communities.

The environment and the economy need not be viewed as opposites. Or strange bedfellows.

Otherwise the dilemma of ecology which is the very foundation of our existence is progress itself. ~ 

Global trends that have been changing the way we live

Lesson on TATAKalikasan, Ateneo de Manila University
87.9 FM Radyo Katipunan, every Thursday) 11 to 12 a.m.

Global trends that have been changing the way we live ... then the Coronavirus Pandemic broke up ... followed by the Russian-Ukraine War ... and now, impending world recession.

Dr Abe V Rotor
Living with Nature School on Blog [avrotor.blogspot.com]

The adage, "History repeats itself," is real: The rise and fall of the Greco-Roman Empire; the Dark Age - aftermath of the Bubonic Plague pestilence; two world wars in succession; and the recent Spanish Influenza (1920-22) which killed 50 to 100 million people. Other lost cultures like the Mayans, American Indians that "history forgot," notwithstanding.

And whose making are these tragic episodes of history? Albert Einstein has this to say, “The world as we have created it is a process of our thinking. It cannot be changed without changing our thinking.” In this era of pandemic and post pandemic, we have yet to prove under the new normal humanity's resilience and resolve to cope up and prove that "history repeats itself for the better." Then, suddenly without apparent warning, the Russian-Ukraine conflict is escalating into war of global concern.  Pessimists both from the old and new schools say it is  the beginning of a third world war.

Global Warming, and Shrinking Nature, paintings by AVR 2015

1. Shrinking Nature - displacement of natural habitats with man-made settlements, wildlife is vanishing both in areas and biological diversity. Nature reserves cannot compensate for such loss, and will never be able to bring about ecological balance as a whole. "It is no longer us against Nature, instead it's we who decide what nature is and what it will be." says Paul Crutzen, Nobel Prize Awardee.

2. Stressful modern living - the higher the status the more stressful life is. The social ladder takes us to the syndrome posed by Paulas'Hope for the Flowers. There is really nothing up there, but a stressful life at the apex of society. The stressors affecting the poor are different from those in higher society. Those suffering of high-status stress find it more difficult to adjust than their counterpart in lower society.

3. Loss of privacy - Yet we always strive to retain our privacy even in public. No way: the computer has all the info about us - true or not; our relationships on various levels, more so with our public image. Hidden cameras are everywhere, on the other hand we too, intrude into the privacy of others. GPS gives us information about places, with minute details, often intruding to one's privacy similar to trespassing.

4. Aging gracefully and Niche Aging - Forget conventional wisdom; gray-haired societies aren't a problem. Longevity is increasing all over the world: the average age of a Japanese is 78 years with America following at its heels with 75 or 76 years. We are quite close to China with at least 70 years. Science and technology, socio-cultural and economic opportunities make ageing a privilege today.

In an article - Niche Aging, author Harriet Barovick said, "...the generic settlement model is starting to give way to what developers are calling affinity housing - niche communities where people as they advance in age opt to grow old alongside others who share a specific interest. Niche living is the latest step in the evolution of the planned retirement community.

5. "Immortal" Food - Food that virtually last forever (by increasing the shelf life), while there is a current trend which is the opposite. Go natural - food, clothing, energy, housing, and practically anything we eat and use everyday. (See article, Living Naturally, in this Blog)

6. Black Irony - Blackness has many connotations and implications - principally, historical and religious. Black means race, hell, disease, death, hopelessness, discrimination. But all these cannot  be grossly weighed as negative or destructive. Today when we talk of black we may be referring to the colored athletes who dominate many sports, great leaders of movements like Wangari who planted millions of trees in Kenya, and not to look far, former President Obama of the US, and the living hero of South Africa, Nelson Mandela. Racial discrimination - racism and apartheid - may soon be a thing of the past. It is because man is created equal beneath their skin, and in fact, by circumstance, the colored races have proved superiority over the non-colored: in schools, scientific discoveries, business, technology - name it and you have a colored standing out.
7. "Handprints, not Footprints" - a more encouraging way to conceptualize our impact in our handprints; the sum of all the reductions we make in our footprints." 
Eye of a dying coral as a result of global warming and pollution by AV Rotor 2005

Says the brainchild of this idea, a Harvard professor. We can reduce the impact of living against the environment - less CO2, less CFC, less non-biodegradables and other synthetics, less pesticides, etc. On the other side of the equation would be the number of trees we plant, our savings on electricity and water. Lesser pollutants, if not arresting pollution itself - and the like.
8. "Your head is in the cloud" - The best way to explain this is in the article written by Annie Murphy Paul. To quote: "Inundated by more information that we can possibly hold in our heads, we're increasingly handing off the job of remembering to search engines and smart phones." Never mind memorizing the multiplication table, or Mendeleev's Periodic Table of Elements. Spelling of a word, its homonym, antonym? Check it out on the computer. Presto! it will correct the word automatically. Search Love, and it comes in a thousand-and-one definitions. Assignment? Search, download, print, submit - just don't forget to place your name. Psychologists are back to the drawing board about learning. They have proposed a new term - transactive memory, a prelude to blending natural and artificial intelligence.

9. The rise of Nones - Nones are people who have no religious affiliation. More and more people are dissociating from organized religions, a kind of freedom to feel more devoted to God, of moving away from the scandals of the church, and money-making religions . For most, they are not rejecting God. They are rejecting organized religion as being rigid and dogmatic. However, a survey in the US showed that spiritual connection and community hasn't be severed by this new trend. Forty percent (40%) of the unaffiliated are fairly religious, and many of them are still hoping to eventually find the right religious home.

10. Living alone is the new norm - Solitary living is spreading all over the world. It is the biggest social change that has been long neglected. Living solo is highest in Sweden (47%), followed by Britain (37%). Following the list in decreasing order are Japan, Italy, US, Canada, Russia, South Africa, Kenya, and Brazil (10%). Living alone helps people pursue sacred modern values - individual freedom, personal control and self realization. In Lonely American, however, Harvard psychiatrists warn of increased aloneness and the movement toward greater social isolation, which are detrimental to health and happiness to the person, and in the long run, to the community and nation.

11. Common Wealth - National interests aren't what they used to be. Our survival requires global solutions. The defining challenge of the 21st century will be to face the reality that humanity shares a common fate on a crowded planet. Global warming, acid rain, El Niño, don't know political boundaries.

12. The End of Customer Service - With self-service technology, you'll never have to see a clerk again. It is an era of self-service - from filling up gas to banking to food service. Swipe your ID card to enter an office or a school campus. Credit cards abound, so with many kinds of coupons, all self service.

13. The Post-Movie-Star Era. Get ready for more films in which the leading man is not "he" but "Who?" Goodbye James Dean, Marilyn Monroe, Marlon Brando, Fernando Poe Jr. Welcome Nemo in Finding Nemo, Xi in Gods Must be Crazy.

14. Reverse Radicalism . Want to stop terrorism? Start talking to terrorists who stop themselves. Conflicts arising from radicalism can be settled through peaceful rather than by bloody means.

15. Kitchen Chemistry . Why the squishy art of cooking is giving way to cold, hard science? There are specialized courses in culinary art, with the chef as central figure with a degree. Home economics has grown into Hotel and Restaurant Management.

16. Geoengineering . Messing with Nature caused global warming. Messing with it more might fix it. Can we ignite a volcano to cool the earth like the eruption of Mt Pinatubo did twenty five years ago? Scientists believe we can divert an approaching typhoon out of its path. Better still abort it at its early stage.

17.Curing the "Dutch Disease." How resource-rich nations can unravel the paradox of plenty. It's true, oil-rich nations in the Middle East - and Holland, and lately Nigeria, where the term was developed - are not growing fast in terms of Gross Domestic Products (GDP). Now compare this is non-oil rich nations like China and Vietnam, which are growing close to 10 percent annually in GDP.

18. Women's Work. Tapping the female entrepreneurial; spirit can pay big dividends. Women's Lib brought the female species at par - if not excel - with its counterpart. More and more women are occupying high positions in government and industries. Women may soon have higher literacy rates than men.

19. Beyond the Olympics. Coming: Constant TV coverage of global sporting events. Boxing grew into various titles, football games in various tournaments fill the TV screen. New sports and games are coming out.

20. Jobs Are the New Assets. A sampling of fast-growing occupations - Actuaries, financial analyst, computer programmer, fitness trainer, biophysicists, translators, manicurists, marriage counselors, radiologists. Need a design for your product? Give  it to an IT graduate with a background in design. Need a kind of product or service not found in the mall or supermarket, search the Internet. Entrepreneurs have taken over much of the functions of big business. Unemployment has given rise to this new breed - the entrepreneurs.

21. Recycling the Suburbs. Environmentalists will celebrate the demise of sprawling suburbs, which left national addicted to cars. Infrastructures will be converted in favor of "green", town centers, public libraries, museums, sports centers, parks. Notice the gas stations along NLEX and South Road, they have transformed into a complex where motorists can enjoy their brief stopover. More and more countries are imposing regulation to green the cities, from sidewalks to rooftops. Hanging Gardens of Babylon, anyone?  If this was one of the wonders of the ancient world, why certainly we can make a replicate - perhaps a bigger one - given all our modern technology and enormous available capital.

22. The New Calvinism. More moderate evangelicals are exploring cures for doctrinal drift, offering some assurance to "a lot of young people growing up in sub-cultures of brokenness, divorce, drugs, sexual temptations, etc."

23. Reinstating the Interstate, the Superhighways. These are becoming a new network of light rail and "smart power" electric grid. This is the alternative to car culture that thrives on fossil fuel and promotes suburban sprawl.

24. Amortality - "non-moral sensitive" or "neutral morality' - whatever you may call it, this thinking has revolutionized our attitudes toward age. There are people who "refuse to grow old," people who wish to be resurrected from his cryonized corpse.
Our Dying Earth becoming virtually a fossil planet, painting by the author

25. Africa , Business Destination. Next "economic miracle" is in the black continent. Actually it has began stirring the economic consciousness of investors and developers.

26. The Rent-a-Country. Corporate Farming, an approach pioneered by the Philippines in the 60's and 70s, is now adopted by giant companies to farm whole valleys, provinces, island, of countries other than their own. Call it neo-colonialism, - these are food contracts, the latest new green revolution, more reliable food security.

27. Biobanks. Safe deposits - freezers full of tissues for transplants, cryotude for blood samples, liquid nitrogen storage for sperms and eggs, test-tube baby laboratories and clinics. Welcome, surrogate motherhood, post-menopausal technology, in-situ cloning, multiple birth technology, and the like.

28. Survival Stores. Sensible shops selling solar panels, electric bicycles, power generators, energy food bars, portable windmill, etc. Attributes: living off the grid, smart recycling, sustainability, consume less, self-sufficiency, basic+ useful, durable lifetime guarantee, hip + cool community, independent, responsible, co-op, brand-free, out of the oven, goodness-driven, health fitness, meditation, bartering, sharing, socialistic capitalism.

29. Ecological Intelligence. There are guidelines now available to judge products on their social and environmental impact. This is new culture characterized by environment-consciousness, environment-friendliness. Here life-cycle assessment and clean-up corporate ecology become an obligation. We are going back - happily and beautifully to a simple and natural lifestyle.

30. Ecomigration - As global warming continues and the sea level rises more and more low lying areas will be swallowed up by the sea. Before this happens, people will have to move to safer grounds. This phenomenon is happening to many island in the Pacific, among them the Kiribati and Micronesia groups of islands.

Do sundials still work?

Do sundials still work?

Living with Nature - School on Blog

The author examines the Sundial in Tagudin, Ilocos Sur, built in the 18th century at the town's plaza.

This caliper designed sundial at the College of Engineering, University of the Philippines, Diliman Quezon City is probably the biggest of its kind in the world. Photo by AV Rotor.

A sundial is a device that measures time by the position of the sun. It is like measuring the lengthening shadow of a standing person or a post, calculating the hour of the day in the process. This practice of telling time by the shadow we make is still common today in the provinces. Thus, a trained person tells the time to fetch children in school, to prepare meals, to go home and do his chores.

Telling time with the sundial is not of course accurate. First, it depends on the longitude and latitude of the place, meaning where exactly is the sundial located. This is important to know the position of the sun in relation to the place. Sundials in the south hemisphere are reverse to those in the north hemisphere. Sundials on the equator are marked differently and adjusted as you get closer to the north or south pole.

The other reason for the lack of exactness of sundials is because the earth's rotation around the sun is not a perfect circle; it is elliptical with the nearest distance called perigee and the farthest, apogee. And the pattern is not fixed year to year.

Today, with the introduction of mechanical and electronic devises to tell time, the sundial has been relegated to the museum, and landmarks, like the sundials in Tagudin, Ilocos Sur and the giant caliper-like sundial at UP Diliman. There are however, architecturally designed buildings to tell time by their shadow, such as Taipei 101 building in Taiwan, and sundials equipped with electronic systems that automatically make the necessary adjustments to the mentioned variables.

A typical analemmatic sundial, also known as a 'Human Sundial'. The person acts as the gnomon, standing in the proper position for the month. This sundial has a second, inner dial to show the daylight saving time , which is adopted in a number of countries.

An equatorial sundial in the Forbidden City, Beijing. The gnomon points true North and its angle with horizontal equals the local latitude. Closer inspection of the full-size image reveals the "spider-web" of date rings and hour-lines. The author had a chance to study some of the inventions of ancient China in 1982 and 1985, among them is this sundial. Near the site are surviving instruments to track celestial bodies, the early Chinese being advance in astronomy.
