"Biologists have traditionally modelled nature using Euclidean representations of natural objects or series. Examples include the representation of heart rates as sine waves, conifer trees as cones, animal habitats as simple areas, and cell membranes as curves or simple surfaces. However, scientists have come to recognize that many natural constructs are better characterized using fractal geometry. Biological systems and processes are typically characterized by many levels of substructure, with the same general pattern being repeated in an ever-decreasing cascade. Relationships that depend on scale have profound implications in human physiology (West and Goldberger 1987), ecology (Loehle 1983; Wiens 1989), and many other sub-disciplines of biology. The importance of fractal scaling has been recognized at virtually every level of biological organization (Fig. 1; Section 5).
"Fractal geometry may prove to be a unifying theme in biology (Kenkel and Walker 1993), since it permits generalization of the fundamental concepts of dimension and length measurement. Most biological processes and structures are decidedly non-Euclidean, displaying discontinuities, jaggedness, and fragmentation. Classical measurement and scaling methods such as Euclidean geometry, calculus and the Fourier transform assume continuity and smoothness. However, it is important to recognize that while Euclidean geometry is not realized in nature, neither is strict mathematical fractal geometry. Specifically, there is a lower limit to self-similarity in most biological systems, and nature adds an element of randomness to its fractal structures. Nonetheless, fractal geometry is far closer to nature than is Euclidean geometry (Deering and West 1992).
"The relevance of fractal theory to biological problems is dependent on objectives. To the forester interested in estimating stand board-feet, a Euclidean representation of a tree trunk (as a cylinder or elongated cone) may be quite adequate. However, for an ecologist interested in modelling habitat availability on tree trunks (say, for small epiphytes or invertebrates), fractal geometry is more appropriate. Using a fractal approach, the complex surface of tree bark is readily quantified. A forester's diameter tape ignores the surface roughness of the bark, giving but a crude estimate of the circumference of the trunk. For an insect 10 mm in length, the 'distance' that it must travel to circumnavigate the trunk is much greater than the measured diameter value. For an insect of length 1 mm, the distance travelled is greater still. This has consequences on the way that the tree trunk is perceived by organisms of different sizes. If the bark has a fractal dimension of D = 1.4, an insect an order of magnitude smaller than another perceives a length increase of 10D-1 = 100.4 = 2.51, or a habitat surface area increase of 2.512 = 6.31. By contrast, for a smooth Euclidean surface, D = 1 and both insects perceive the same 'amount' of habitat. The higher the fractal dimension D, the greater the perceived rate of increase in length (or surface) with decreasing scale."

Cattail plants are often seen on towels and kitchen decanters and placemats...but you might notice fewer of them along the roadways and creek beds. In their place, you might see an invasive plant, like Phragmites (tall waving grass-like fronds) or like loostrife (magenta flowers). But the cattails are part of the environment that belongs here. They clean the waterways and they provide food for many other living things in our environment. Help preserve the native species. "Dr. J"
You must have traditions, too: Favorite recipes, special songs, sledding down the hill at Smith's farm, hot chocolate by the fire...
The holiday season is just a few months away! First Halloween, then Thanksgiving, and before you know it, you'll be stuffing stockings! Christmas, Eid, Hannukah are special times families gather. Maybe you celebrate a special holiday that few others do. But, typically, the holidays are time to gather with family and friends, to think and reflect over the past year, and to look forward to the future year with goals and plans.
Many holiday traditions involve gift giving. It is important to pay attention to the family budget. No sense going into debt for the holiday gift giving. That will only bring stress. You can write a poem, or make drawings, or wash the car or bake a cake or in a million other ways let someone know you think he or she is special. Make jam, cook breakfast, keep your room clean without being asked. I am sure you can think of many ways. But if your budget allows for splurging a bit, don't worry, CouponChief* is here for you. Just remember not to over do it.
You can make a wish list of your household family members (and pets...) and think of the most amazing gift you would make or buy for them, if you could. These coupon offers may help:

In the nearly empty lot of a McDonald's not far from the coast one stormy summer's day a Sea Gull was trying to open his lunch sack.It had been conveniently left there by the previous guest, Mr. Litterbug. A Crow passed by, then alighted on the nearby macadem, pausing to say, "Hello," to Sea Gull and then watching him.
The Sea Gull picked up his lunch bag and flew up in the air. When he was high enough, he dropped the bag. Then, quickly flew down to look at it. Again and again Sea Gull flew up in the air, dropped his lunch sack and flew down again. Ever so patiently Sea Gull tried again and again. Finally he gave up, said Goodbye," to Crow and decided to fly farther in-land since the clouds over the sea looked ominous.
"Do you want help with your lunch," asked the Crow before the Sea Gull left?
"No, I'm going to find something else to eat," and the Sea Gull flew away.
"Why bother to look elsewhere?" said the Crow; "We have plenty of food right here." But the Sea Gull was already too far away to hear. The Crow walked over to the lunch sack and using the long toes as a hand, gently unfolded the top of the bag and then tipped the bag over and ate the lunch. Then the Crow knew:
It is best to wait patiently than to give up before reaching your goal.
This is a true story, except for the anthropomorphism at the end (And of course, the talking.) The actual incident, which the author watched, took place around 1999. Of course there are many other morals that could be drawn by the reader, such as...
- "Then the reader knew:
- 'Littering is frustrating to wildlife and drastically alters their diet," or,
- "Sea Gulls eat shell fish that they drop from the air, smash on the rocks and then, nibble on the pieces, while Crows use there feet and their minds to help them get their food," or,
- "Old technologies need to be updated as situations change, or,
- "Science education helps us preserve our environment, save our wildlife and sustain the Earth."

Breathe in the silence
Then open your eyes.
Look at all the evidence,
Breathe out in sighs.
Look up above and
See the clouds, sun, moon,
Or stars numerous as sand
In desert dune.
Smell the scented wood,
Aroma of pine.
Lift your heart toward all that's good.
Feeling just fine.
Go to the city,
Visit children's schools,
Also schools town and country
Learning not fools.
Many things to learn and see
One, two, three
If you're a living to earn.
Math, Science, History . . .
Theater, Art and Music.
Balanced with reading.
Listen well when teachers speak

Many people are traveling at this time of the year. Even if you are at home all summer, you can act like a tourist for a day or two. Try new restaurants, go to museums. What about going to the botanical gardens, the park or the zoo? Talk or write about what you see. Draw pictures, too. You don't have to be a great speaker, writer, or, artist, yet. Just enjoy the process. Develop ideas. Write a persuasive essay about where you'd like to go, or, a descriptive essay about where you've been. Focus on one aspect, such as science...what scientific things did you learn on your trip? Did you see lichens (http://ocid.nacse.org/lichenland/ ), for example?
Remember travel, whether local or global, is a great part of education. Vocabulary is developed as you see new things and learn what they are. Traveling across states and or countries contributes to geography knowledge. And, in a car full of people, skills for getting along are developed. "Geography," is a classic car game: http://www.liveandlearn.com/cargame.html.
If you are you looking for hotels, motels, resorts, or vacations rentals. Check out this web site. It may have something just for you and the pricing on Hotel Reservations seems competitive, ... Great discounts are available, even for global travel.
Remember the famous back-to-school essay that focuses on your summer vacation...before you go away think up some questions that will give you something interesting to write about. Check out this: (http://www.abcteach.com/free/w/writingbrainstorm_summervacation.pdf) after you have thought up some of your own ideas. Discuss the similarities and differences with those found here.
Have a great trip. Relax. Eat, sleep and play well. Go back to school rested and full of ideas. Post some of your trip events, drawings, and essays here. I can’t wait to hear of your adventures.
Has anyone else got any tips? Add them to the comments.
You can learn about organisms that indicate clean air. You will learn many other things about these organisms and you will learn about the sustainability of the Earth.
Here is a site to help learn the jargon of lichens is a FUN WAY!

Here's a web site on a talk from the Botanical Society of America meetings 2002 . People keep requesting it, so I posted it here. If it doesn't link automatically type in the address. http://www.noblenet.org/bhcc/league/BSA2002ShipmanSmith.ppt
PayPerPost is a unique way to fund college. It is a good way to improve writing skills, too. You can review a product, write about it and earn money ( get paid to blog). Once you have a blog, you can get it approved and can then start making money. You'll get the message, "You are our newest Postie..."
I am just such a new, "Postie." What I love best about PayPerPost, is that I get to write about new things. I signed up initially to help pay for my son's college and other expenses. I heard about PPP on a blog my son wrote and linked to .
There is a strong community at PayPerPost that I am just getting to know. I haven't made any friends yet, but, I believe I will soon. I have learned how to Blog, what a tag is, how to post links. I have updated my computer skills so that I know what the teen-agers are doing...
I hope you will try PayPerPost and get paid to blog! Then, tell your friends about it.
What are you going to do with all the money you earn!?!?!?! As for me, I am going to help fund my son's college and if any is left over, I will pay off any other outstanding bill(s). Once I am financially independent, I will set up a foundation involved in sustainability of the Earth and will also help fund scholarships, if I make enough.
