TO LIVE IS TO KNOW?
I think of this in many ways. I learn things by experience. Hands on. You can tell me how to transplant a sappling, but until I do it on my own and feel its roots, feel the soil, understand the sunshines effect, etc, I really don't know. Some people can grasp things without having to do it with their hands and sometimes I can almost..... but when I get it in my hands, is when I say I know it.
But to ask is to live to know? There are so many directions of that. As I live I know. But as I know more, the only thing I really know is that I know so little. Many people think that since they have lived it, they know, but in truth they may only know for themselves. We are so complex. And maybe they don't really know. Perhaps I know how to transplant a baby tree, but I have really only done that in michigan and california, so do I know how to transplant trees in africa?
I think to live is to be open to understanding. To at least know that there is no one way. But if we don't at least try one way we are so much further from knowing anything in the first place. I guess I know that I can't really stand people that think they know everything.
MEMORY AND MAGIC
A touch of irony that we just read this article as my housemate and I just relaxed to a blockbuster movie about magic called the illusionist. It was not great, but it did prompt a conversation about how come people are so facinated by magic. It makes sense that the great magicians had such insight to peoples psyches as they seem to all factor in how the common brain would react to a situation and alter it. We talked about how we are creatures of habit, and when someone comes in front of us to show us such a divergence from this habit, it is full of so much awe. The irony of the article it that the magic is using our habit of memory to trick us. And then we are amazed. In short, we are so backwards.

CELL BIOLOGY AND TCM STUDIES
Alas, you asked the question just when I decided that this weeks material would suit me for my final paper. I guess I'll give away some hints to what I was thinking about. What is this energy medicine? Perhaps it is linked to what is happening in each one of our cells. They are focused on producing energy for the entire body. Like Qi, this energy is not visible through a microscope, but it is accepted that the cells are making ATP to provide a usable energy. TCM shows this energy to flow in a more direct pathway (the meridians) much like biology shows the blood to travel through certain pathways. I believe that our needles and our herbs work with the ATP, boost the production of ATP and help guide it to the place in most need of healing.
HOW CELLS DIVIDE: Mitosis vs. Meiosis
I suppose in a battle of mitosis vs. meiosis, mitosis would win as it is producing a fully formed new cell while meiosis is making a zygote which requires another sex cell to reproduce with it. But I know this is not what you were getting at. For some reason, I really liked biology in high school and remember many things from it. I think I mentioned this in other blogs, but it was in this class (in a religious high school no less) that I first started thinking about my spiritual path. I was so amazed by the tiny details that made up living things and started to believe that this was all too genius just by chance. But that is not what you were asking about as well. In short, I am amazed by cell division. I am amazed that with each level of meiosis we come closer to the chance to form something totally unique when that cell finds its match. I am thankful for mitosis as my cells replacing themselves with new, healthy ones..... what could be better?

DIVERSITY OF SPECIES
When I think about diversity of species I automatically go to plants in my environment as I am installing a native garden in my home. And as the bay area has such a specific ecosystem, there are native plants that thrive here.... and they are not too limited to their number of species. I am amazed by the selection of plants/trees that are available and present in our parks. Here if you go for a stroll in tilden, it is shocking how many different plant species there are and I would guess over half of them are native. In michigan (where I used to live) a walk in the park was a game of trying to name that invasive plant, which left less diversity of plant species. Still, there are grasses and blackberries, ie, that get in the way. I read that before the invasive grasses came to these parts, even though we are rain free for seven months, all the hills were always covered with green. Now we have our usual browning.
Still it is important to note that we live in a city, and as humans populate an area they may bring a diversity of culture and races, they strongly diminish the diversity of plant species, as our footsteps are so large. I know we took the homes of hundreds of animals, and try to be friendly to the deers that seem at home (Even though two ate my entire veggie garden over the weekend).
The real neat thing to me is that the fog plays are very interesting role in the diversity of plant species. Redwoods, for example, know how to slap the fog with their needles onto the ground and water their roots (which need tons of water). Our live oaks need small amounts of water and learned to ignore the fog, or just not grow where it is too heavy. This gives me hope that as long as we don't cut them down, they will survive here over other invasive species.
LINKS ON CELLS
Ahhh, good old biology. It is always great revist the cells in living organisms as it is flat out amazing. Every detail has such a important function, and there are so so so many cells of this detail that makes us living things. How did this come to be? LIke I said in a previous blog, science is what makes me visit my spiritual questions. It is so awe inspiring. And when you put a human cell next to a plant cell, it is so neat to see the comparisons as we are all in this to live.
SPIKES GALLERY
Wow! These are works of art. It makes me think about images that we are drawn to in art or design, often already exist in nature. Perhaps there is something subtle in our subconcious that finds comfort with images that we share life with. My favorite is the Opercularia articulata as it looks like a beautiful flower. Neat.

GROWING BRAIN CELLS IN THE LABORATORY:
Ahhhh, sometimes I wish I could grow extra brain cells so I could process these complicated issues with more ease. When I was 20, it seemed that issues such as these were so much more black and white, and as I age, things increasingly have become grey. Perhaps part of it is having had more experience with life and even having to face some of these choices, and the other perhaps is the fact that all these issues that are under much debate, are in fact under debate because there are at least two valid sides.
In specifics to brain cell research, my initial reaction is to be awed, as our leaps in science flat out amaze me. My next reaction is to be scared, because how fast we are moving in the realm of science feels like a speeding train that might crash anywhere, anytime.... and there is no way to tell.
All I can say is now that I know I am motivated by love, if someone I loved dearly was blind, and had a chance to see again because of this research, I think I would be supporting its process. There is so much we take for granted, and as have being someone that was once quite ill, when you are sick you will do almost anything to find your health. I don't think it is my right to get up and say that this research is immoral at the stake of millions of people retaining their vision. I just hope that somewhere out there, some of the research is investigating possible future side effects.
And in the end, one of the cores of this research is to help people. Yes, perhaps many of the cores is to make money on a miracle drug to sure blindness. I have intentions in this world that have more than one core, and I think it is impossible to act in pure altruism. I think people lump technology with scienctists too often and forget that most of what is polluting the planet is in fact the huge businesses that decided it would be neat to design a new, bigger, faster, better something.....
One of the Definitions of the “Chemistry of Life”:
"Biochemistry is the study of the fundamental mechanisms of life at the molecular level"
Of all the definitions, this one helps me understand what biochemistry really is, as it combines how I understand biology and chemistry. Where biology is the study of life, and chemisty is the study matter at a molecular level. Together we get to study life at a molecular level. Ironically enough, when I studies this in high school, at a religious school no less, this was the first time in my personal path that I started to toy with the possiblity of a God. I love that a hard science provoked this.
One of the ANIMATIONS:
I tried to watch an animation of DNA cells replicating, but as usual, I could not get my computer to perform this function. But I could just picture all the spirals seperating and finding new pairs and new sprirals....... The lovely double helix.

Week #10
MY SEMICONDUCTOR OF THE WEEK:
I choose Aluminum (Al), atomic number 13, atomic weight 26.981538, because I am interested to follow up on the theories that aluminum is linked to alzheimers disease, and my lucky number is 13..... so I could not resist. It says that aluminium is the second most commonly used element in this world (right behind iron), and if it is unhealthy for us living creatures.... this can be scary. Here are some examples of where aluminum is used to show a bit how dependent we are on it:
Transportation (automobiles, aircraft, trucks, railroad cars, marine vessels, bicycles etc.)
Packaging (cans, foil, etc.)
Water treatment
Treatment against fish parasites such as Gyrodactylus salaris.
Construction (windows, doors, siding, building wire, etc.)
Cooking utensils
Electrical transmission lines for power distribution
MKM steel and Alnico magnets
Super purity aluminium (SPA, 99.980% to 99.999% Al), used in electronics and CDs.
Heat sinks for electronic appliances such as transistors and CPUs.
Powdered aluminium is used in paint, and in pyrotechnics such as solid rocket fuels and thermite.
In the blades of prop swords and knives used in stage combat.
(from wiki).
As for its link to alzheimers, I thought this site described it well:
http://www.alzheimers.org.uk/Facts_about_dementia/Risk_factors/info_aluminium.htm
In short, it is possible, but so hard to test as aluminnium is almost everywhere. Nonetheless, it is still important to know there is a possible link as it is not too hard to avoid at the very least injesting it or putting in on our boides.
LINK TO: Welcome to Chembalancer and Green Chemisty, balancing equations:
As usual, when you give me a game to play, especially with numbers, I will happily learn and digest the harder concepts of balancing equations and sorts. I don't know why we did not do it this way in high school. Maybe it is the libra in me, but i like finding balance in numbers.

Week #8
An Inconvenient Truth......
In my second viewing of this film, I am still so shaken by what it has to teach. Kudos for anyone who can get through this stream of thoughts. My bike ride home from class is a hard 30 minute climb and I don't even remember it as I was stewing over some details. Now two weeks later, I feel it is not consuming all my thoughts.
I am struck with so many emotions in reaction to this film. Fear, anger, sadness, frustration, and a tiny bit of hope.
This issue is flat out scary. The reference he made to the ice age happening in only ten years horrified me. This issue is pressing and it seems that we are doomed. I am so happy that Gore made a movie about this and I think it was very wise to make it a moral issue over a political issue. As it is a moral issue, and if it were political perhaps many more people would not have seen it. I flat out can't believe that there are skeptics to global warming. The signs are everywhere around us, and the statistics that he provided were pretty irrefutable. So I am scared. I don't think unless major political policies are changed that we have much hope. I am so curious what would have happened if Gore became our president. If we would all be driving electric cars. So, thank you Mr. Gore for making a movie that explained the issues in a mature way, and trying to show how pressing this is.
The anger comes from my personal hopes. I have devoted my life to living green. It really is a lifestyle. It effects what I eat, how I travel, how I want to raise my children, etc. I am floored by how many people are not doing anything. Being single and "dating" a bit, even in the bay area, I am considered eccentric for living this way. That is crazy! This is not an issue of race, class, or gender, this is our future. And the hardest part for me is I feel I am doing all that I can. I have to live with waste of all the millions that don't know or don't care. It seems unfair. Not that I am a saint, but sometimes I wonder why I try so hard.
Perhaps on a personal note, all that I really wanted out of this life is to be a good mom. And now it seems that a huge footprint is to have a child. So with my lifelong dream to bare a child one day, I am leaning towards adopting instead. This seems so backwards. Why do all the people that don't do anything about the problem get to pop out as many kids as they want, and then the people that know the issue have to make this choice. Furthermore, what do I want for my child's future? I don't want them having to make boats to find the only land that is left from the icecaps melting. And what if that happens in the next ten years, perhaps I won't even get to live my dream. (Its not like I asked to be a rock star, wanting to raise a child seems like a fair dream). So I am pissed.
Nonetheless, I love nature. It nourishes me, and for that I am so deeply thankful that it seems only natural to try to live in harmony with it. I am so scared of who we have become. So thank you al gore for putting us in our place (even if every single shot of you in the film is of you using some sort of fossil fuel..oops). I wish you could more people what to do.
Thank you Michael Moore for putting us in our place. Sicko was another important movie.
Thank you Leonardo Decaprio, I have not seen his new movie, but big cheers for a "heart throb" making a movie about serious green urban designs. I guess change is in the air. What makes us so numb? I have to believe that it is that we don't know how to help.
yikes, I am going to break this blog site.

MY ALKALI EARTH METAL OF THE WEEK:
CALCIUM
Atomic number 20, atomic weight 40.078
I chose calcium as it has always been important in growing food. Adding calcium to the soil, in the form of dolomite, gave the plants more fibers in their vegetative states, and also helped balanced the ph of the soil.
When I was vegan, people always used to hound me with the question of how was I getting my protein, but the real question should have been how was I getting my calcium, as it often comes from dairy (and we all tend to eat too much protein). There were many foods that I was able to find that were high in calcium, which included: seaweed/ kelps, kale, broccoli, collards, almonds, dendelion greens and okra. When I grew these foods (other than the seaweed and almonds), I noticed upon soil testing that they absorbed more of the calcium from the soil than the other plants. Pretty neat.
THE FOODS IN OUR KITCHEN
This is a fun one, as we try to grow most of our own foods. Over the winter, we had a very green kitchen full of kale, collards, lettuce greens, broccoil. Our color variety came with the carrots and beets. But now we are moving into the season where the fruits of the veggies can grow and we are starting to have a more colorful kitchen. I love the summer colors in the garden. Our summer squash is blooming, adding some yellow. Soon we will have many different color tomatoes, and this year I planted three different color string beans. (While I ran the CSA I learned that giving out a colorful box of veggies was a treasure). I am addicted to eatting green food, but also enjoy a colorful plate. It is neat to think that there are certain cravings based on a chemisty basis..... I'll get back to you.
THE LINKS
Geez, I learned something new in just the first paragraph in the link about minerals. I love rocks and crystals, I am a novice on the subject, but find them healing to touch and view and always take time to examine them. I thought they were catagorized by their color and the article explained that the worst way to ID these minerals is by color, I guess when I think about it, it makes sense, but I am going to have to ask someone with more experience to ID the crystals on my alter.

WHAT IS A MOLE?
A mole is essentially a handy tool to tell us the numbers of atoms or molecules in a substance. It is handy, because the number of molecules in a substance is so so so large, that the number actually holds too many digits to even begin to record it. It is used in direct connection to avogadro's number, so when there is an avagadro's number of objects, it is called a mole. I like the comparison to a dozen bagels also equals 12 bagels (well, in NYC it is 13 bagels). It is a very helpful unit of measurement. We can save a massive amount of ink by not having to write all the zeros.
The link reported a way they use avagadro's number and moles in making glazes for ceramics. I was happy to read it as it is the first time I have seen the numbers being applied to something that I have an interest in and can apply it too. Though I am still happy to just follow a formula to make the glaze and glad someone else is doing the math. (Even though I like math, I don't love huge numbers).

Though I am still happy to just follow a formula to make the glaze and glad someone else is doing the math. (Even though I like math, I don't love huge numbers).

HYPOTHESES
I like having to write about what a hypothesis is, as so many people translate them as fact........ A hypthesis is an "idea" that someone has about how something "works" and then a series of test are done to prove or disprove this idea. For example, the theory of evolution by Darwin is a hypothesis, not a fact. Yes, the ideas of natural selection and adaptations prove true in many areas of nature, but that does not mean that there are no other reasons for why a marigold is orange or a redwood tree likes fog. When I get caught in talk with someone that is skeptical of chinese medicine and insists on having the scienticfic method applied to prove its worth, I try to remind them that most things in science are based on hyptheses. I think the truth can change all the time.
I just checked the link included for this question and was happy that it supported my rant. It answering the question, it stated it best, that if a hypothesis is proven true it DOES NOT become a law of science. Amen.

MY INERT GAS OF THE WEEK
This week, I choose the element: NEON. With an atomic number of 10. And an atomic weight of 20.1797.
I choose to investigate neon, because as I child my whole family was allergic to animals but we are allowed to have fish. My favoite were the small neons, that we called "glow in the dark fish" because of their amazing metallic bright colors. I though it would be neat to see if there is a connection.
Here is what I found about neon:
(I like this one).... A very common element in the universe, it is rare on Earth.
We are all familiar with neon lights often advertising some sort of beer or cola, well there is a relation. Neon is a colorless, inert noble gas under standard conditions but gives a distinct reddish glow when used in vacuum discharge tubes and neon lamps.
Wiki tells me that it is also used in
vacuum tubes
high-voltage indicators
lightning arrestors
wave meter tubes
television tubes
Neon and helium are used in helium-neon lasers
Liquefied neon is commercially used as a cryogenic refrigerant in applications not requiring the lower temperature range attainable with more expensive liquid helium refrigeration.
As for the neon fish, I could not find a direct connection to the element on the periodic table, but it was fun reading about them.

EXTRA CREDIT
MY GREEN HOME
My housemates and I take pride in trying to keep our home as green as possible. Each month we strive to pick a new area in the house to be more green. It is fun and easy, especially since we all want to leave small footprints. Here are some things we make an effort to use:
Only green, biodegratible cleaning products, i.e. dishsoap, shampoos, laundry deterg, etc.
We use lead free paints and deck sealers.
We use recycled toilet paper, and have cloth napkins...so no paper towels.
We use tupperware, so no need for plastic wrap of foil.
All our lights are the new energy saver bulbs.
We have air pressures on all the shower heads to save water.
We keep bricks in toilets to save water.
We buy bulk organic foods.
This month we are trying to figure out a way to reuse the bath water to water our garden (a grey water system). And as we are all students, we are trying to figure out ways to use less paper.
I think we are doing well.

Class #4
CATALYST OF THE WEEK
A catalyst is a substance that increase in rate of a chemical reaction that is itself not consumed by the overall reaction. I think of it in terms of "a catalyst for change." For example, Martin Luther King Jr's efforts were a catalyst for change in the civil rights movement. He physically did not change through all his work, but his words triggered major "reactions" in this country for change.
My catalyst of the week is: Platinum, atomic number 78, atomic mass 195.
Many musical bands hoped to get a "platinum" record, which would act as a catalyst to reach more fame.
From a chemisty point of view, platinum is used in many chemical reaactions as a catalyst. It is used in jewelry, has been used as a catalyst to make crucibles (I love this one), also used to make "special containers" (not sure what they mean), a catalyst for laboratory equitment, dental crowns, as an anti-tumor agent and to make standard weights and measures.
And as I felt this is relevent to green chemistry, Platinum acts:
As a catalyst in the catalytic converter, an optional (though often mandatory by law) component of the gasoline-fueled automobile exhaust system.
As a catalyst in fuel cells. Reducing the amount of platinum required (and thus cost) is a major focus of fuel cell research.
So, I am not sure I am thrilled with what platinum is the catalyst for, but I am very excited about the catalyst for change.

REVIEW OF WATER CONCEPTS:
When exploring carbon, there are many quotes that says it is the element that is the basis for all life. Well, from my own experience in life, I would argue that perhaps water, H2O, is the most important chemical bond that makes up life. This link showed how two elements of hydrogen are stongly linked to an element of oxygen.....forming our famous water molecule. This site says how these molecules move around alot, and find that a nice image when I think of the ocean. It is hard to believe that the ocean, that is alive in its own right, is made up of these small molecules that do their own dance. Perhaps helping to explain the magic of the ocean.

MOLECULAR STRUCTURES OF CARBON
They say that carbon is the basis of all life on earth. In looking at its elemental makeup, it is clear that carbon has many differnet molecular structures and has a great affinity for bonding. Because it has this potential to form many bonds (mostly stable covalent bonds), it is said that carbons is "known to form nearly ten million different compounds" and seems to be present in most chemical compounds. It makes sense that carbon is so present as it forms the hardest substance in the world, diamonds, and one of the softest substances, graphite. Its own yin/yang perhaps.
I often think of carbon as one of the three elements in making up glucose, which when we ingest it, we convert it to energy. In this process, we form ATP, which Dr. Yeh pleased me to give a western view of what Qi is. He said, ATP = Qi. The basis of life, and finally a way I can explain all this to my family (who are all firm science nerds).

Week #3
MY TRANSITIONAL METAL OF THE WEEK: MERCURY
Before I chose my metal of the week, I thought it would be helpful to reasearch what makes an element a transitional metal. This is what I found: (Points taken from wikipedia)
"Transition elements tend to have high tensile strength, density and melting and boiling points. As with many properties of transition metals, this is due to d orbital electrons' ability to delocalise within the metal lattice. In metallic substances, the more electrons shared between nuclei, the stronger the metal."
The characteristics that most transitional elements have in common is that they often form colored compounds, have a variety of different oxidation states, at least one of their compounds has an incomplete d-electron subshell, they are often good catalysts, they are silvery-blue at room temperature (except copper and gold), they are solids at room temperature, they form complex ions, they are often paramagnetic.
When I think about a "metal", I often think about gold, iron or many of the elements that fall into this catagory.....all elements that seem to be very solid at room temperature. Then I looked at the periodic table and saw that Mercury was part of this group. I chose this element because I never think of it as a solid metal, and I also thought this would be a good time to find out what all the fuss is about mercury poisoning amoung eating fish (one of my favorite foods.
Alas, Mercury:
Atomic mass of 201, atomic number of 80, meaning 80 protons and electrons and 121 neutrons. Its symbom is Hg.
I was correct to assume that it seemed strange that mercury is solid at room temperture, as this is the one element in the transitional metal group that is not.
In searching about mercury poisoning in fish, I found that it is not mercury alone as an element that is harmful but it is poisonous in soluble forms such as mercuric chloride or methylmercury, and something to be careful of while eating fish. Most articles say that eating a small amount each week is safe, but like everything.....who is to know? Here is what I found:
"Mercury enters streams, rivers, lakes and oceans primarily through rain and surface water runoff. Bacteria can then convert it to an organic form called methylmercury -- the form that is dangerous to people. Although mercury levels are almost always low in water bodies, methylmercury biomagnifies up the food chain. When small fish with low mercury levels get eaten by bigger fish, the amount of mercury biomagnifies. For this reason, long-lived fish and top-level predators like swordfish and shark often have the highest mercury levels. According to EPA, mercury concentrations in fish can be 1 to 10 million times the mercury concentration in the water."

Week #2 continued
REVIEW OF THE LINKS:
Of course I chose the third link, "Elemenets, Compounds, and Mixtures" because it provided moving pictures of what it was explaining. I tend to absorb information better when there are diagrams to help me visualize the material. This link was defining some basic terms of chemisty. Basically, an element is only one kind of atom. A molecule is two or more of the same element. A compound is two or more of different elements bound together, such as H2O (water). And a mixture is two or more differnet elements and/or compounds physically intermingling.

Week #2
ELEMENT OF THE WEEK
This week, I am Nitrogen. It was not hard to pick, as over the last 12 years as a farmer, Nitrogen has been a big part of my life. Most vegetables and flowers need a large amount of nitrogen in the soil in order to produce. When I have had beds lacking in nitrogen, I noticed that the "grow" stage of the plant is dwarfed and the plant never fully matures. There are other elements that are needed to complete the healthy cycle of a cultivated farm plant, but in my experience, without nitrogen, there is no hope.
The two ways I have worked on getting nitrogen into the soil is by ammending the soil and by crop rotation. Ammending the soil means adding nitrogen rich "products" to the soil and mixing it all together. On the farms I have worked on, we used manure heavy compost as a main ammendment. Cows, horses and chickens produce a very high nitrogen manure, which in time breaks down to usable compost. I have also used bat guano (a chinese herb, no less), as they can harvest it and seperate out the nitrogen part of the manure from the other elements. Bloodmeal is another ammendment rich in nitrogen.
Crop rotation is very common in organic farming, and also practiced on large scale corn and soy commercial farms. Legumes, which are plants with a pod (such as beans), "fix" nitrogen in the soil. What that means is they are one of the few plants that thrives on carbon, and while they grow, their roots omit nitrogen in the soil. (Thank you legumes). I use them often to fix nitrogen in our soils by planting fava beans, snow peas and vetch. Large scale farms plant soybeans the year after they plant corn, as corn is a "heavy feeder" or nitrogen and omits carbon in the soil. So the next season, soybens are planted, which thrive on the carbon and feed the soil with nitrogen. It is a nice marriage.
OZONE DISCUSSION
Some of the buzz words that came up when I talked about "the ozone layer" with some friends over dinners were: CFCs, styrofoam, hairspray, refrigerators, air conditioners, sunburns, Antartica, and the 1980s. Most people at dinner thought that the environemtal issue of the ozone layer being distroyed, was a problem solved. One person said, they were not sure if the problem was fixed, but thought that the status was improving. My friend, who studies history, informed us that there was an international agreement in the early 90s, banning things that were hurting the ozone. He thought that this global effort was in fact a success story. All were surprised that the issue is still present. I showed them the articles that we got in class as I was not very clear on how the issue of ozone still is something to work on. I will have to do more research before my next discussions to support my knew knowledge.

extra credit week #1
1.
I took the fun brain game. They gave me the element, and I had to choose the correct symbol. On the medium level, I got an 8 out of 10. I was able to guess well based on others that I knew. If I had to do it in reverse, I would have gotten one right for sure (iron), and maybe three right with guessing the first letter. Yikes.
2.
I took the element table quiz. I am confused a bit and I thought to go by the equation for the atomic mass which is protons plus neutrons. I guess I was wrong, because #3 would have been 14 if that was true. Perhaps I got lucky on the others. Oh, this is so much more fun than memorizing herbs.
1. 6 ... CORRECT
2. 12 ... CORRECT
3. 14 ... INCORRECT... the correct answer is 7
4. 53 ... CORRECT
You got 3 out of 4 correct

BIO
I am an organic veggie farmer turned acupunture studend, and I am in awe. All the things I have done in my wonderful life thus far have all been harder and more amazing then the last. I grew up in New York City and knew from a young age that I wanted something different. I think I have granted that wish as I have been so forturnate to see the world, learn to grow food, dwell in wonderful communities and most of all, continue learning. I feel very lucky to be 31 years old, and be immersed in something that makes my brain think in so many new ways. I also know that this field will provide learning for the rest of my life, so I am at peace. The love of my life is my dog, muna, who turns five on saturday.
THOUGHTS ON LAST WEEKS LECTURE
I am always happy to talk with people about the growing concern for our need to make serious change for the survival of our species. As I said in class, sometimes I feel like I am doing so much as an individual to make concious choices about the environment and it feels like I am not going to make any difference. But I also remember when I got into growing organic food people thought it was just bug filled, dirty food, and now, 12 years later, it is available in most stores and prefered by more people than I ever imagined. I have faith that most people want to do the right thing, only they don't always know the truth of their impact. I continue to hope for more education on what individuals can do to lighten their footprints, as I continue to try to find ways to make mine even lighter. I also have learned that I have to make these changes and do this work without anger, as I don't thing change responds well to that. I anxiously await for a government that steps in and educates us. If things keep going the way they are, unless you know how to make a boat out of dollar bills, money just ain't what it claims to be. ;-)
RESULTS OF QUIZ
1. chemical or physical change:
burning wood-chemical change
crushing rock-physical change
disolving sugar in water-physical change
rusting of iron-chemical change
2.pure substance or mixture:
Sugar in the only pure substance. I got the other three wrong. After milking cows, I am a bit surprised by that one. Perhaps if it was not "table" salt, it would be pure. And steel?,,,,,,,,,glad this is not the final.
3.cup of black coffee.
b. homogenous and impure. I got it right, which was a relief after the last question.
4.The boiling of water:
d. physical....physical. I got it 50% correct. I thought the boiling of water was a chemical change...but I stand corrected.
