Amazing 1960s Afghanistan by Dr. William Podlich


1960s Afghanistan, through the photographs of Bill Podlich...............
 
 
In 1967, Dr. William Podlich took a two-year leave of absence from teaching at Arizona State University and began a stint with UNESCO (United Nations Educational, Scientific and Cultural Organization) to teach in the Higher Teachers College in Kabul, Afghanistan, where he served as the “Expert on Principles of Education.” 

His wife Margaret and two daughters, Peg and Jan, came with him. Then teenagers, the Podlich sisters attended high school at the American International School of Kabul, which catered to the children of American and other foreigners living and working in the country.

Outside of higher education, Dr. Podlich was a prolific amateur photographer and he documented his family’s experience and daily life in Kabul, rendering frame after frame of a serene, idyllic Afghanistan. Only about a decade before the 1979 Soviet invasion, Dr. Podlich and his family experienced a thriving, modernizing country.

 These images, taken from 1967-68, show a stark contrast to the war torn scenes associated with Afghanistan today.
“When I look at my dad’s photos, I remember Afghanistan as a country with thousands of years of history and culture,” recalls Peg Podlich. “It has been a gut-wrenching experience to watch and hear about the profound suffering, which has occurred in Afghanistan during the battles of war for nearly 40 years.
 Fierce and proud yet fun loving people have been beaten down by terrible forces.”

 "I grew up in Tempe, Arizona, and when my dad offered my younger sister, Jan, and me the chance to go with him and our mother to Afghanistan, I was excited about the opportunity. I would spend my senior year in high school in some exotic country, not in ordinary Tempe... Of course, there were loads of cultural differences between Arizona and Afghanistan, but I had very interesting and entertaining experiences. People always seemed friendly and helpful. I never got into any real difficulties or scrapes, even though I was a fairly clueless teenager! Times were more gentle back then." - Peg Podlich (Pictured at right).

"In the spring of 1968, my family took a public, long-distance Afghan bus through the Khyber Pass to visit Pakistan (Peshawar and Lahore). The road was rather bumpy in that direction, too. As I recall, it was somewhat harrowing at certain points with a steep drop off on one side and a mountain straight up on the other! I remember that, before we left Kabul, my father paid for a young man to go around the bus with a smoking censor to bless the bus or ward off the evil eye. I guess it worked - we had a safe trip." - Peg Podlich.

"Afghan girls, as well as boys, were educated up to the high school level, and although girls (and boys) wore uniforms, the girls were not allowed to wear a chadri (burka) on their way to secondary school. Able young women attended college, as did the men." - Peg Podlich

"For the year that I was in Kabul, my family lived in a house in Shari-Nau, up the road from the Shari-Nau Park.Ę My parents had lived in Denver, Colorado in the 1940s. My mother would say that Kabul reminded her of Denver: about a mile in altitude, often sunny, with beautiful mountains in the distance. I thought it seemed somewhat like Arizona because of the arid landscape and lack of rain. Since I was born [in Arizona], it was very easy for me to appreciate the stark beauty of the landscape there in Afghanistan." - Peg Podlich.

"AISK's last year was 1979, so the school had a 20 year history. AISK was located on the same campus that currently houses the American University of Afghanistan (on Darul-aman Rd in west Kabul). In 1967-68, there were about 250 students attending AISK and 18 graduating seniors." - Peg Podlich

In Tempe, I had walked four blocks to school; in Kabul a school bus stopped outside our home. Jan and I ran out when the driver honked the horn. On the bus, we were supervised by Indian ladies, wearing saris of course, and were driven with about 20 kids back through Kabul, around the hill to the west side of town." - Peg Podlich

A Buddha statue in Bamiyan Valley- a UNESCO World Heritage Site. The two largest statues (not pictured here) were destroyed by the Taliban in 2001. "That was a bumpy, rough trip, but I'll never forget how wide and green the valley was or how monumental those two Buddha statues were, carved into the face of the cliff... The statues were a magnificent sight, even to someone like me, who did not really understand the history or technical achievement of those statues." - Peg Podlich

According to UNESCO, "The cultural landscape and archaeological remains of the Bamiyan Valley represent the artistic and religious developments which from the 1st to the 13th centuries characterized ancient Bakhtria, integrating various cultural influences into the Gandhara school of Buddhist art. The area contains numerous Buddhist monastic ensembles and sanctuaries, as well as fortified edifices from the Islamic period. The site is also testimony to the tragic destruction by the Taliban of the two standing Buddha statues, which shook the world in March 2001."

Dr. Bill Podlich on a hillside in Kabul. "My dad was a professor of Elementary Education, specializing in teaching Social Studies, at Arizona State University in Tempe, Arizona from 1949 until he retired in 1981. He had always said that since he had served in WWII... he wanted to serve in the cause of peace. In 1967, he was hired by UNESCO as an Expert on Principles of Education, for a two-year stint in Kabul, Afghanistan at the Higher Teachers College... Throughout his adult life, because he was interested in social studies, whenever he traveled around (in Arizona, to Mexico and other places), he continued to take pictures. In Afghanistan he took half-frame color slides (on Kodachrome), and I believe he used a small Olympus camera." - Peg Podlich. 


 

Amazing Queen Elizabeth’s Aging Process


International Banknotes That Show Queen Elizabeth’s Aging Process

Queen Elizabeth II has, of course, been pictured on British currency for much of her reign, but she has also appeared on the money of various British Commonwealth states and Crown dependencies. 
With such a long reign (61 years so far) and so many nations issuing money with her image on it over the years, there are enough banknote portraits to construct a sort of aging timeline for the Queen. The age given below for each portrait is her age when the picture was made, which is not always the same as the year the banknote was issued (more information can be found at this interesting site maintained by international banknote expert Peter Symes). Here is Elizabeth through the years, on money.

1. Canada, 20 dollars, age 8




2. Canada, 1 dollar, age 25




3.  Jamaica, 1 pound, age 26




4. Mauritius, 5 rupees, age 29



5. Cayman Islands, 100 dollars, age 34



6. Australia, 1 dollar, age 38



7. St. Helena, 5 pounds, age 40



8. Isle of Man, 50 pounds, age 51




9. Jersey, 1 pound, age 52




10. Australia 5 dollars, age 58




11. New Zealand, 20 dollars, age 60




12. Gibraltar, 50 pounds, age 66




13. Fiji, 5 dollars, age 73




14. Jersey, 100 pounds, age 78




15. Canada, 20 dollars, age 85



Back to Canada, where it all began, and where they like their Queen a bit laid back.

Most Amazing Discovery - Turn Plastic Waste Into Oil


-- Save your plastic ~~~




This is one of the most amazing and break-through in Technology I have ever seen!!!Why aren't we doing this now????

I think we should all do what we can to save what we are destroying! Not surprised at this at all,
just a case of Japanese ingenuity and perseverance. What is more important would be the marketing and very low cost to make it mandatory to have one of these in every home.
Just read the subtitles and watch. What a great discovery!

POSSIBILITY OF CONVERTING PLASTIC INTO OIL

This video reminds us of the popular video showing how to convert Salt Water into Fuel, which is not practically easy and profitable - as the process consumes more energy than it produces. Although the present story sounds too good to be true, it holds up to scrutiny and does not violate any physical laws. Yes, it is a fact that plastics are generally recycled back into oil in massive facilities, and this is possible because most of the plastics today are made from oil. The Japanese inventor here, Mr. Akinori Ito has in fact built a tabletop machine called Blest Machine which can do the same task safely and cleanly.
However, it should be noted that Blest is not the only company to be able to turn plastic waste to oil. There are few other companies across the world that are trying to make this process profitable. Agri-Plas, an Oregon-based plastics recycler company, is the first one in U.S to convert unwanted and typically unrecyclable agricultural plastics into crude oil. The company has even shipped this oil to a refinery for commercial processing. Then there are other companies like Agilyx (formerly Plas2Fuel), the Envion Oil Generator, and few others that you can read from the reference section below. The second video is a CNN news report of the Envion Oil Generator. The process these companies (and individuals) employ to convert petroleum-based waste plastic into fuel is known as Pyrolysis.

PYROLYSIS

Pyrolysis is a thermochemical decomposition of organic material at elevated temperatures without the participation of oxygen. This involves simultaneous change of chemical composition and physical phase.
In present case, as explained in the first video, the plastic waste is heated at high temperatures to decompose and convert into oil and other by products, which can be used as fuel. The Blest’s conversion technology uses a temperature controlling electric heater, inside which the machine can process polyethylene, polystyrene and polypropylene (numbers 2-4) plastic, but not PET bottles (number 1). The machine gives a crude gas that can fuel things like generators or stoves and, when refined, it can also be pumped into a car, boat or a motorbike. When this gas is cooled down, it produces oil, which can again be refined for using in various ways. Depending on the quality of plastic, the machine can convert 1 kg plastic to about 1 liter of oil. Reports suggest that this process of converting waste plastic into oil is a good deal as well.
The Blest company also has a refiner machine for separating hydro carbon oil from this crude oil, which converts this mixed oil into Gasoline, Kerosene, Diesel oil and heavy oil equivalents. However, the company does not guarantee this conversion, as it depends on the type of plastic materials used. Moreover, this plastic to oil conversion process has some cons, along with some pros.

The Pros:

  • All those dirty waste plastics going into landfill and leaching chemicals can be avoided by this process. It can be utilized in a better way.
  • Saves both energy and carbon emissions, and depending on regional landfill costs, it can also be more cost efficient.

The Cons:

    • In long term, there may be environmental risk from the gas emissions, the impurities and potentially toxic compounds that will be left behind in this process.
    • If this oil production process becomes successful, use of plastic may not be put on check. 
    • THE FUTURE SCOPE

      According to a 2012 study prepared for the American Chemistry Council, by the research organization RTI International, these Pyrolysis conversion technologies that turn plastic waste into fuel have developed to the point where they are likely to be commercially viable in just 5-10 years.
      The study also points that although there’s plenty of plastic waste available to convert into fuel, plastics-to-oil technology alone is not likely to be an energy cure-all. This is because the extent of oil consumption around the world is massive, and this plastic conversion into oil cannot cater all those needs. The RTI study says:
      “Given the developmental stage and the current capacities of technologies, our preliminary estimates suggest that conversion technologies would offset significantly less than 1% percent of annual North American oil consumption. The average size of a plastics-to-oil facility is in the range of 10-30 tons per day. If there were 100 plastics-to-oil facilities in North America by 2015, conversion production could offset approximately 6,000 -18,000 barrels of oil per day, assuming 1 ton of plastic yields 6 barrels of oil. In contrast, total consumption of crude oil in North America is forecast to be 21.57 million barrels per day in 2015.”
      Regarding the future of this plastic to oil conversion, the RTI study concludes saying:
      "The future of these technologies will depend heavily on the success of first-generation facilities, but some successes are already coming to fruition. Two facilities have off-take agreements, and almost all of the surveyed vendors have recently received awards for innovation and/or clean energy solutions. Conversion technologies should be considered an emerging, viable option for managing non-recycled plastics and MSW (municipal solid waste) in the near future."
      So only time and development in these technologies will tell us how efficient, safe and profitable these conversion processes can be.

World's Most Amazing Insect - BEE

World's Most Amazing Insect - BEE

New images, captured as part of the US Geological Survey's bee inventory, depict bees in a range of colours including deep blue and bright green. Researchers spent almost 10 years capturing photographs of North America's 4,000 different bee species.Dozens of individual pictures of each species, taken at different ranges, were combined to make composite images with a greater depth of field, allowing the insects to be studied more closely. The system was originally developed by the US Army to capture high quality images of pests found on foreign bases, so that they could be identified by experts.Sam Droege, head of the program, explained that the appearance of different bee species varies enormously but that most are ignored because they do not sting us and do not resemble the most common types.
He said: Bees come in so many different shapes and sizes because there are so many sizes and shapes to flowers – the two co-evolved together and created specialised systems where certain species of bees only pollinate certain species of plants, using their special bee tools and bee abilities.
Most people are completely oblivious to the existence of the many species of small solitary bees nesting in their lawns because they do not sting and don't match our mind picture of what a bee should look like. Some are as small as a grain as rice, while others have no stripes and do not sting – hardly fitting the common perception of what a bee is. While the most common varieties such as honey and bumble bees share a similar, distinctive colour pattern, hundreds of lesser known types have a completely different appearance.
