BIOLOGY/WEEK 1

Our group had discussed the tetrachromatic phenomena of "super vision" in women today.  It is estimated that only 2 percent of women have the genetic mutation that results in the extra retina cone that allows them to see 100 million colors!  Most humans are "trichromats" meaning their eyes contain three kinds of cone cells which provides access to roughly one million colors.  I find it interesting that the tetrachromacy mutation appears in women with sons or fathers who are colorblind.  This could be categorized as a superhuman trait!

I was also fascinated by another group's topic of how sea mammals communicate with each other.  Clearly, we are still trying to figure out their communication using sound for orientation and group organization.  This is the first time I've heard that their sophisticated system of sound may actually project images to each other during communication.

    Oh cool! I wonder how much more prevalent this mutation will become in the future or if this will eventually die out since it is only passed by the male gene. I'm also curious how the women with this "supervision" can actually interpret colors. It's in a way that's not even possible for us "three coners" to even comprehend. A super painter's palette must be 100x the size of a normal painter!
    Also yes, I was also fascinated by the communication of sea mammals. It would be like having instantaneous communication of text pictures to someone else. I wonder if the pictures that are sent are perceived the exact same way from one animal to another or if there is some room for individualized interpretation. Great read!

When an object has symmetry, it can be divided into two pieces which are mirror images of each other.  Although we are always striving for symmetry, there is an underlying asymmetry within everything.  As an esthetician, I find this in my work on a daily basis.  Clients come to see me hoping that they can turn their brows into the perfect symmetrical work of art.  I do my best to perfect the mirror imaging of their brows but in reality, there is always some form of asymmetry no matter what.  I believe that we seek symmetry in our daily lives because it is built into our DNA.  We see this in art, music and all that we create.  Our animal instincts recognize that the symmetry reflected in facial features and bodily proportions is a better indicator of good health, so prospective mates may be chosen for healthier offspring.  Symmetry is also equated with the divine in many religions since it represents the ultimate perfection.  Through our cr...

RACHELLE'S PHYSICS BIO

I was born and raised in Honolulu, Hawaii and have been living in the Bay Area with my family since 2004.  I've worked an esthetician for the past decade by helping clients achieve their skin care goals.  I am now dedicated to being a student in Chinese medicine school and fulfilling an interest that was sparked long ago as a young child in my grandmother's kitchen.  She brought her knowledge of village medicine from China to the United States and used it in our household to treat various illnesses and ailments.  I am hopeful that my current journey will be a bridge for the knowledge of the inner and outer landscapes of the human body.

PHYSICS: WEEK 6

Organized chaos can be described as the process of gaining desirable outcomes through a state of disorder.  This might reveal a hidden natural order that governs all living things, even when the environment seems chaotic.  If we think of the principles of yin and yang, we see that there is always an element of both within each other.  Therefore, chaos resides in order and order resides within chaos.  Organized chaos provides an environment for unpredictability and ultimately, creativity.  The lack of a system of rigid order results in numerous creative possibilities and outcomes.  Chaos can be seen as an environment of freedom that provides a breeding ground for systems of natural order to arise A fractal system is a complex, non-linear interactive system which has the ability to adapt to a changing environment.  Such systems are characterized by the potential for self organization, existing in a non-equilibrium environment.  Chan...
