Here’s sharing the photos I have taken so far with my iPhone before it got too dark to take good pictures. The nature walk was organised by the Nature Society of Singapore for their members on 24 August 2013.
The nature walk concluded at the edge of the rainforest and I walked for another 40 minutes or so to the bus stop near the foot of Bukit Timah hill to take a bus and transfer to another bus. Overall the walk was refreshing as it felt good being in Nature, and among the more familiar flora and fauna such as moths and mushrooms I encountered along the way, it was the first time I saw fireflies in this country, so it is quite a rewarding experience.
(The photos of the nature ramble below were taken using Canon PowerShot SD750.)
Regarding the intriguing quote about our origin, especially the origin of the iron in our blood being from distant stars billions of years ago, I was googling about this to get a better understanding, and came upon this article.
“Here’s an amazing fact for your next cocktail party: Every single atom in your body—the calcium in your bones, the carbon in your genes, the iron in your blood, the gold in your filling—was created in a star billions of years ago. All except atoms of hydrogen and one or two of the next lightest elements. They were formed even earlier, shortly after the Big Bang began 13.7 billion years ago.”
The article went on to say that after an ancient star died and exploded into a supernova, dispersing its elements into the surrounding space, the stardust may eventually form a solar system consisting of planets and the sun, such as the solar system we live. The mystery remains as to how the atoms and molecules on our planet eventually become alive as we know it.
“Just how those atoms and molecules that ended up on our planet went from non-living to living remains one of the great unanswered questions in science. But where the elements came from to start with has now been worked out, in broad strokes anyway, to astrophysicists’ widespread satisfaction. It is an amazing story, isn’t it?”
I am also reminded from health articles I read so far that iron is important in our blood as it carries oxygen in the red blood cells. For some reasons, dark green leafy vegetables and beans, among others, contain more of this stardust than other plants. Who would have thought iron in stars can become life sustaining mineral for us?
Perhaps a greater mystery as to what causes iron in stars to become life sustaining minerals in our body is what holds everything in the universe, including the atoms in our body, together. It may take a moment in time or an eternity to appreciate the wonders of this mystery.
