見風 Now I see the wind, Cheju Island Korea Oct 0 2004
When I slowly walked down to the shore from the cottage early in the morning. I didn't know that there was such a strong wind.. It's so windy that I even couldn't breathe well. The island of Cheju is very famous of three things, rocks, diving sea women and wind.
제주의 아침...
제주의 아침...한라산이 보이는 어느 오름의 중턱에 자리한 펜션에서
산책 삼아 해안가로 천천이 걸어 내려 왔다..
..풀..나무..거미..돌담..귤..
그리고 바람...
바람이 어찌나 세던지
가슴에 잔뜩 힘을 주어야 겨우 숨을 쉴 수 있는 정도 였다..
바람은 눈에 보이지 않는다.
항상 다른 사물을 통해 그의 존재를 알린다..
멀리 위에서 바라 볼때는 전혀 그가 있음을 알지 못했다.
나의 호흡을 힘들게 하고
그 뻣뻣한 야자수 잎을 사정없이 갈대처럼 나불거리게 하는
제주의 바람을 온몸으로 느끼며
상쾌하고 즐거운 wind shower를 즐겼다..
어떤 순간은 마치 무균실-무먼지실을 위한
Air Curtain을 지나는 듯 하기도 했다..^O^
敬 Marvelous neighbors, Southern part of Korea 2004
Everybody on earth will be thrilled by the news of 'Just one day before the fifth Earth-year anniversary of its landing on Mars, NASA's Mars Exploration Rover Opportunity found a tiny simple looking earth worm kind of living thing!!!" But nobody but few professionals cares on how beautifully created arthropods have been living with us such a long long time in our back yards.. ^,~
覺 Sometimes I need more Legs and more Eyes.., Somewhere in the Mountain in Korea 2004
(*wikipedia for spider)
Most spiders have four pairs of eyes on the top-front area of the cephalothorax, arranged in patterns that vary from one family to another. The pair at the front are of the type called pigment-cup ocelli ("little eyes"), which in most arthropods are only capable of detecting the direction from which light is coming, using the shadow cast by the walls of the cup. However the main eyes at the front of spiders' heads are pigment-cup ocelli that are capable of forming images. The other eyes are thought to be derived from the compound eyes of the ancestral chelicerates, but no longer have the separate facets typical of compound eyes. Unlike the main eyes, in many spiders these secondary eyes detect light reflected from a reflective tapetum, and wolf spiders can be spotted by torch light reflected from the tapeta. On the other hand jumping spiders' secondary eyes have no tapeta. Jumping spiders' visual acuity exceeds by a factor of ten that of dragonflies, which have by far the best vision among insects; in fact the human eye is only about fives times sharper than a jumping spider's. They achieve this by a telephoto-like series of lenses, a four-layer retina and the ability to swivel their eyes and integrate images from different stages in the scan. The downside is that the scanning and integrating processes are relatively slow.
As with other arthropods, spider's cuticles would block out information about the outside world, except that they are penetrated by many sensors or connections from sensors to the nervous system. In fact spiders and other arthropods have modified their cuticles into elaborate arrays of sensors. Various touch sensors, mostly bristles called setae, respond to different levels of force, from strong contact to very weak air currents. Chemical sensors provide equivalents of taste and smell, often by means of setae. Spider also have in the joints of their limbs slit sensors that detect vibration. In web-building spiders all these mechanical and chemical sensors are more important than the eyes, while the eyes are most important to spiders that hunt actively.
Like most arthropods, spiders lack balance and acceleration sensors and rely on their eyes to tell them which way is up. Arthropods' proprioceptors, sensors that report the force exerted by muscles and the degree of bending in the body and joints, are well understood. On the other hand little is known about what other internal sensors spiders or other arthropods may have.

力學 What a Dynamics, Lakeshore Toronto Feb 2008
Fluid dynamics is notorious for its complexity of mathematical manipulation. Taking-Off from the ground might be simple physics compared to the flying dynamics of the bird.
They fly whatever they like to.. gliding, hovering, diving, vertical landing, turning direction in the air at the same spot.. It's really amazing to see them how delicately created with such sophistication to fly..
美聲 Gekko, Hotel Robles Managua Nicaragua Oct 23 2005
One of the most cute tropical lizards.
They even sing like bird.. maybe a serenade..
I felt into sleep in the night and woke up in the morning upon their serenade.. ^,^

眞珠 Crystal Pearls in the Forest, Bayview Don River Summer 2008
On a rainy morning in spring time..
All the living things in the forest were chanting for the glory of life just rejuvenating again..
