    I used to get this weird sensation in my head when I had fever in my childhood.  You may call it a natural high.  Let me try to describe it as much as I can remember.  I could see a part of the wall in the room I was sleeping, but the wall starts to move slowly, at first, moving away from me.  The wall accelerates to enormous speed, and places itself to a very large distance away from me.  In retrospect, it is just like Starship Enterprise going to Warp 8 from stand still, and going to the other side of the sector.  Then, next minutes, the wall comes back to where it was, again, accelerating from standing still to enormous speed.  The sensation I felt was a mixture of fear of the speed and fear of being alone in the vastness of space; simultaneously it was strangely exhilarating because of the speed and the vastness of space.  
    This wasn’t all.  A small imperfectly spherical organic object lands on my forehead.  The object at times can bounce on my forehead at low speed, much like larva-lamp’s oil goes back and forth between the top and the bottom.  And, at times, it speeds up and travel the vast space, as I described for the wall, but this object on return from the trip, it becomes incredibly heavy, and crushing my head.  The object can shrink to a very very tiny occupation in space, but kept its heaviness.  The object also expands itself in like a balloon, but without a bound.  It expands to engulf the size of universe.  These motions comes back and forth, as if it had its own life cycle.  
    My father had always told me the next morning recovering from the fever that I must have had a nightmare.  As I got older, I got fewer and fewer episodes, and eventually I lost the sensation nearly all--adulthood takes the romance of pure sensations.  We have instead a fear of unpaid bills, and accumulating debt and pressure to perform, etc., becomes your nightmare!  
    Anyway, yeah, it’s weird!

Tadpole Shrimp
    You just have to look at it!  It is a weird-cool creature!  I just love its shape!  Go google yourself on tadpole shrimp.  You will find a lot of hits.  When you see its shape, you will understand why I like it.
    I had to walk about a mile on a country road to my elementary school everyday.  Nature was plentiful.  On the way to school, I walked through cultivated mulberry trees for silk worms and rice fields, and crossed  two creeks and two small foot hills.  There were plenty to see and play with.  
    Among many interesting things to see, my favorite was tadpole shrimp.  The name is misleading.  It looks more like a miniaturized  horse shoe crab; it is about an inch in length.  The shape of this creature is so primeval.  In fact, its ancestors have been found in Germany from a layer of rocks some 300 million years ago, i.e. Carboniferous Period of Paleozoic era.
    Later I learned that tadpole shrimps live in its adult stage only for few days.  Those little creatures really made an impression on me.  The tadpole shrimps I saw, perhaps only few times, fill a large part of vivid memories of my childhood, as if I sat at a side of the small puddle for days on end.
    In one sense, tadpole shrimps drew me into the world of science, giving me a set of eyes to look at nature in more details.  I remember I was so fascinated by these little creatures.  
Things that drove me into science:  Tadpole Shrimp and Saturn
Majestic heavenly body, Saturn
    I had a friend whose family was seemingly richer than most of the kids I hang around with.  He had a telescope!  One night, he invited several kids in the neighborhood to show us the heavenly bodies.  I had a book about the space given to me when I was 4th grade or so.  I knew little more than most of the kids who went to see his telescope that night.  I can name all planets, and I can describe how they look, including the ring of Saturn.  
    We looked at some stars.  OK.  Good, but it was just flickering lights.  This attitude quickly changed when I saw the ring of Saturn!  I was completely mesmerized at the field of view in the eye-piece.  Wow!   Saturn had its beautiful blue-green soft glow on the ring!  I suppose the feeling is similar to the one that encounters a painting of Rembrandt or a beautifully crafted jewel.  I began to wonder how and why Saturn looks the way it does.
    When Hubble space telescope was launched and started to send those awesome pictures of celestial bodies, I had very similar feeling about the images to that of Saturn that night.  Now I have a larger body of knowledge and appreciate those images more than ever.  I even thought that I may have made mistake in choosing my career path to chemistry.  Why didn’t I choose astronomy?
