Knowing and Uncertainty

Photos this week have nothing to do with my essay - Here are a collection of doors seen in Peru...

Most Americans, when asked how they gain understanding of the world, will tell you that they rely on “good reasoning”, “follow common sense”, think  “critically” or “logically”.

But for some, this only goes so far… The issue between creationists and evolutionary biologists keeps resurfacing… The Pew Research group found that 42% of Americans see themselves as creationists.  This creates an issue in our schools and what we teach our children.
 

First lets get one thing clear – Science is not about “proving” things to be true.  Science is about seeking available information and finding the most probable solution to a problem based on the evidence. As new knowledge becomes available, explanations are adjusted and corrected.  For something to be a “theory” – does not make it unreliable.  It simply tells that “it is the best conclusion” to fit the known facts.  No one study or test “proves” or “disproves” something. It is abhorrent to scientists to think of manipulating data to support a desired outcome.


The belief in creationism is a “belief”… created by people of faith to explain the origins of the earth, and all life…passed on my tradition over the centuries… but not based on ongoing tests or scientific research. This interpretation is not open to question and examination.


It is not fair, and not possible to have an open debate between the two positions.  One system disregards anything that does not support the faith position.  The other is open to all new tests and results to reach a conclusion. 

Far from all Christians support the literal stories of Genesis. Many modern day Christians see Genesis as an allegorical story – a metaphor. These Christians see Genesis as the ancient explanation of an early people…. The story tells how these people experienced God active in their world.  In the Genesis story, God says that creation is “good”.


My goal as a science teacher is to encourage students to investigate – to examine, to learn how to design tests, to gather new verifiable information.  People who base their position purely on “belief” are very limited in how far they can engage in these actions.

I am concerned for young Americans who are prevented from learning how to think critically.  News articles this week pointed out that Bob Jones University Press sells a Life Science textbook (used by many voucher eligible schools).  This book teaches students that dinosaurs and humans lived at the same time…. And many have even lived side by side within the past few thousand years.  Great dragon-like-beasts are mentioned in the Bible, and this is offered as “evidence”.  The books advocate that the student must decide between belief in God and belief in evolution.  This misses the point that for many Christians today, it is enriching to combine a belief in evolution with an understanding of a God for whom creation is ongoing.


It is recognized by biologists today that life on earth is undergoing constant change.  Evolution is a continuous process – natural selection in allowing the most fit organisms of all species to survive. Understanding the impact of the rapid human population expansion, global climate change, and human impact on our planet are imperative for our survival as a species.


I have a fear that the US is producing a population that is not competitive with much of the rest of the world in scientific knowledge.  Not only does the pursuit of deeper knowledge depend on producing individuals training for new cutting edge research; but the national policies, that support new programs, depends on an educated population to encourage and support the programs.  Schools in much of the rest of the world do not face the conflict over teaching rigorous scientific knowledge and the pursuit of scientific reasoning methods.


Someone recently told me “I’m not sure that I believe in evolution”.  This person is an example of someone confusing their beliefs with their ability to logically assess evidence.  The evidence is there – we can choose to ignore it but that doesn't remove the existence of the evidence.

How can people without scientific knowledge understand the major biological issues of today?  - Genetic engineering, emergence of new microorganism by mutation, new crop development, medical treatments, the rule of mutations and adaptation resulting from human impact.  Those people that say they don't trust scientific problem solving are going to be left behind in the competitive global economy of the future. The question is are we training students to be ready for the new world economy…

I am curious why many people mistrust science.  For those without knowledge, they don't understand how science works.  Concepts are growing increasingly complex - and in depth understanding requires long study – and this is not possible in all the important topics of current study.  Also scientific knowledge is constantly changing – so no one explanation is the final “truth”. Most of these changes are minor ‘tweaks’ – but for many we want final definite answers.  At times we discover that our explanation is inadequate and then it is necessary to return to basic questions and seek more complete answers. But this is how science works – new questions – demand new research – and better more inclusive interpretations. 

 

Perhaps it is the loss of certainty that leads many to feel uncomfortable with the scientific process, and sends people back into reliance on a comfortable set-in-stone belief system.  But just because such beliefs are more comfortable doesn't make those approaches more honest or effective.

Good resolves!

Thomas Wolfe - said " You can never go home again!"  What I think he meant was that as we live our lives we are changed and we can never return to the way we saw things before the new experiences occurred.  That applies to travel as well...

When I return from a trip,  I come home with a fresh perspective. It is a chance to look again at my habits - of - life and see in a fresh perspective what I might want to change.  

For one, I want to know what is going on in the world – but it is so easy for me to become compulsive about seeking out excessive news programs.  In Peru, I checked headlines, read a little… and that was all.  At home there are newspapers, in depth investigative reports, internet, TV, radio… Now that I’m home, I resolve to not once more overdose on ‘news’ just because it is available.

When I am at home, with a kitchen loaded with good food, it is so easy to “go hunting for a little snack” – In Peru we ate a good satisfying breakfast, a midday “comeda” and a snack in the evening for “Cena”.  I wasn't aware of feeling hungry and I lost a few pounds!  Can I follow this pattern at home?  I am full of resolve.

In Peru, when we needed to travel, many of our excursions involved walking- far more than at home.  Here my car beckons to me from the driveway. “Take me” it says…  I do walk the dogs– I am active in my garden – Part of the problem at home is that my city is not designed for walking to the places that I need to go… When I do walk – I see more, often find interesting people to talk to, and feel good about myself. Perhaps the issue is really how I choose to allocate time.

There are opportunities for new adventures every day here as well as Peru.  Routine schedules eat up my day…  “Come on, John, what can we do today to change the routine?” What fresh experiences are just waiting to be discovered?    

Will I keep my good resolve?  Will old habits draw me back?  Judging from past experiences. i would say - partly, probabily... but not entirely.  Travel does change the way I see the world.

For right now I can say that I  experience the most  'culture shock' when I come home.  I like the stimulation of travel and I feel a little "ho hum" to come home...  Oh well - Adventures come in all sizes and flavors... I just have to be open to seeing them...

Video link of the week:  We shared breakfast with an Australian couple in Cusco... They recommended this video series - After watching them - I do too!  https://www.youtube.com/playlist?list=PLOKWcH1zBl2kfnCwyyZWk5MW28lgaNa7L


A sampling of photos from the many I brought home

Those Inca folks knew how to make a trail that lasts!

Hats give clues to identify- The women with tall white hats are "mestizo" (part Spanish, part Indian), the others belong to distinct regional groups.

Massive Inca stones - each stone shaped to fit exactly - no mortar required... The large stone is over 3.5 ft. in length and shaped without metal tools.

Notes de Peru - 5

Whether it was the Andean herbal tea prepared by the cook of our hostel in Pisac or the vegetable soup from the German expat friend – Judy is feeling better on Monday. “Something she ate” is the general diagnosis.  Still, since she is not up to full speed yet, we decided that it would be a good time to move on to Cusco. Every day her energy level improves.  By Thursday, food is again looking interesting to her.

6.17… Cusco is a ‘tale of two cities’. – If you visit the San Blas district there are wall to wall-fancy boutiques selling to the visiting tourists – much of the merchandise is identical between shops, and prices are high.  The artisanal market is much the same… One of the leading industries in Southern Peru is tourism – mostly people headed to Machu Picchu. Wherever in the world you go, when you have a large number of tourists present, the culture and the economy change in an effort to make a profit from the visitors.

Cusco elevation 11,000 ft.

There is nothing wrong with traveling as a tourist – for some, time is limited, it may suit those who don’t know the language, or feel intimidated by a culture that they don't understand.  Judy and I are tourists, but we have our own way of traveling.  To see more, we limit the area that we hope to visit… We have sources like the Lonely Planet and Moon Guidebook series for each country to be a good starting point in planning our journey. We try to find a balance between  planning time for cities and small towns, nature, and foot-travel rather than spending our time being led around by guides. Our goal, as we travel, is to connect with the local culture and people.  We enjoy the process of fending for ourselves in a culture different from our own – solving problems and finding our way.

To see the second city of Cusco visit the San Pedro Mercado and the narrow streets below that point.  This is where the indigenous community comes to buy vegetables, meat, beans, bread, cooked food, herbs and clothing, a place for shoe repair, a place to sell surplus goods, a section for the over 100 varieties of Peruvian potatoes, iron work, coca leaves, & chocolate. At the moment, in the market there are vast supplies of sugar cane and coconuts being offered. It is a vibrant place for meeting and talking, sharing and laughing.  All prices are flexible and bargaining is expected.  This style of market has changed little since ancient times.  Judy is having a fine time selecting a variety of goods and bargaining for a sales price.  Bargaining here is a friendly back and forth exchange – and if you don't like the final offer you can always walk away. 

Peru is not a 3rd world country but a developing one – sections of cities and towns have growing   middle class homes and well stocked shops…However the middle class people we have met still remain connected to their cultural roots. 

It feels like an old friend for us to return to Cusco - In some ways it is a city version of the Incan villages we have been visiting…We are staying in a charming place – the Ninos Hotel – where profits go to support street children.  A Dutch woman started the program years ago – and they now have 2 hotels and the Hacienda where we first stayed.  By the front door is a wicker basket for left over buns from the hotel café. Any child can knock on the door and ask for bread – they get their choice.

The city itself was a center of early Incan culture in pre-Spanish times – it was a city of great riches, looted by the Spanish… who removed vast amounts of gold and other riches to Spain. Incan origins are apparent in the large closely fitted stone-work in walls and walk ways - an Incan landmark, in the layout of older streets, and the remaining indigenous cultural patterns among the people.

For the month of June, the city is celebrating three things: Its' history, both' Catholic , and Incan traditions.  All of these are manifest in daily events, parades, concerts, and exhibitions.  Each day there are a variety of special activities.   We thought the parades in Ollantaytembo were grand – but here they are spectacular.  An endless sequence of parade units go by – each unit has a 10-foot figure of a saint figure mounted on a large wooden frame carried by 16-20 strong men, who dance their way under their heavy load.    The figures are brightly colored and surrounded by flowers.  Each unit is followed by a brass band playing loud Peruvian music… (I will miss the variety of music here when we return home.) The streets are packed so full with people that movement is impossible. There is also an event called “Platos typicos de Cusco” that appears to provide food for all –donations accepted…  I see piles of cooked guinea pig, chicken, cheese, bread, and the drinks popular in Peru… I asked who is buying all this food – and was told anyone who wants to contribute… they have tables set up to feed several hundred people at a time.

And to make it more interesting– Cusco is like a city following the ‘American world series’ - on steroids… now is the time of the World Cup of “football” (soccer to the US).  This is truly an international event – and followed here with intense energy.  It’s really nice that even smaller countries can compete well against larger countries.  The blockbuster event so far has been that previous champion Spain has lost two times to be removed early from competition.

6/20 One last excursion today … Negotiated with cab driver to take us to the location to catch a 'collectivo' – found bus instead of collectivo to Pisac – got out at the 13,500 ft. mountain pass – explored three important ruins.  It felt good to walk free in the mountains with strange birds, llamas, many wooly sheep, and the music of flowing water.  The high mountains here are so different from our Sierra mountains in California.  The people are so willing to be helpful when we don't quite know the way.  Snow of the peaks above us, flowers along our way, llama and sheep noises as they graze.

Snapshots de Peru - 4

6/13
Last day in Ollantaytambo. The ’dueno’ in our pension suggested that we ‘had’ to go to “Naupaiiglesia”…other local people helped us refine the trip to make it even more interesting… and so after another incredible breakfast we walked down our narrow street with the flowing water in the stone lined ditch.  We went to the Mercado (market area) and climbed into a collectivo about ready to leave – and off we went… We were dropped roadside near a small pueblo and walked steadily uphill for a couple of hours up another of the amazing canyons of the Andes.  Incredibly steep walls, a river forming bends and turns in a narrow flood plane, a narrow gauge railway, and a very narrow road.  
Today the sun was extraordinarily hot – and we were relieved to climb high enough to find a breeze.  Farmers along the way kept us on the correct path…and we inquired frequently.  Finally the site.  We left the “camino” and walked along narrow gauge rail lines for a distance, until we located a trail that led up to the ruins.  At first it was easy going, but it became progressively steeper until we were climbing hand over hand past steep terraces and rock walls.   This site is different from others here – it predated the time of the Inca – and represents a different belief system.  For these people, when the earth was formed there was no light and no dark – only a constant twilight. During these times the spirits were very strong in the land.  When the Sun God “Inti” brought night and day, the Naupa spirits were forced to retreat to the high mountains. Here the spirits lost much of their power at all times except dawn and dusk.  The grotto we visited was considered a “portal” for the spirits – and was a place of worship.  It is said to be dangerous to health to visit the site in dawn or dusk, when the spirits were most active. (The sun was shining bright when we were there).  When I entered the grotto I found a fresh earthen pot containing a libation for the spirits, also burnt Palo Santo – a local wood burned as sweet incense, along with shells from the ocean. Such evidence indicated that the spirits are still held in high regard by some of the local people.  Here in the grotto it was cool and pleasant to look down on the valley below.
After a rest it was time to climb down from the heights to the trail and we started back to the main road… we were hoping to hitch hike – but not a single vehicle came by… So we walked back to the main road  where we had more luck and got a collectivo back to town  - just in time for a late comida. Note – here we are eating 2 big meals a day – one in the early morning, one about 2-3, and a light snack in the evening.

 6.14     The large  unified Incan nation was only possible because of the excellent foot trail system that united the communities.  A system of human runners could deliver a message from one end of the kingdom to a far distant region within days.  (Much like our pony express – but with human runners).  Yesterday we hiked 6 hours along a trail from Qantus Racca down to Acchapata and on to Pisac. There is a great elevation change in the trail so we started the day early with a taxi ride to the top - Qantus Racca. Here the elevation is well over 11000 ft.  We found masses of tourists from busses at the trailhead – but lost them quickly as we got a short distance along our way.   Along our trail we visited a variety of Incan sites – some centers of residence, others military centers, government, astronomy/science, and religious sites.  The entire trail offered us incredible views of the Andes; much of the trail was carved into rock with an intense cliff drop-off to one side, with a drop of several hundreds of feet, and a wall rising high above us on the other side. The trail was wide enough to lead a string of heavily laden llamas.  It has been said that next to Machu Picchu this is the greatest Incan site.  We came away with the thought that this is different but in many ways equal in grandeur of Machu Picchu… it certainly offers more variety of communities and structures, and offers grand vistas for the entire region.  At one point I was taken aback to look over the edge of the trail and realize that I was inches away from ‘yikes’!… with no rail or warning of any kind. Today’s experience was incredible! And we went immediately to a favorite restaurant for a grand comida, however a bit late.  It is operated by a German expat woman, Ulrike’s – she has a great take on Peruvian dishes – but also wonderful German deserts.

6/15
Today is market day in Pisac.  Many indigenous people come down from the high lands to sell vegetables, herbs, and craft items.  However much of the regular items for sale are tourist schlock – the kind of stuff you see in all tourist centers …much of it is mass-produced.   The tourists are rushed around on a “few hours here and a few there” tours, and they miss so much of the real Peru.

Judy seemed to pick up a strange ‘bug’ today – so she has slept a lot and I have been doctoring her.  Our favorite restaurant in town is the previously mentioned Ulrike’s. She helped me select food for Judy’s sick tummy. (Not cheese cake).

We are generally sleeping over 8 hours a night here – nights are cold as air moves down from the higher mountains… most hotels are providing us with thick down comforters – and we have often been so warm we open a window.  Our current hotel supplies thick heavy wool blankets – we are sleeping under the great weight of 3 or 4 of them…
