Another great read called The World Without Us , this time on a best seller by Alan Weisman. This is a book that hypothesizes what would happen to Earth if mankind disappears overnight. It does not attempt to explain why and how humans can suddenly vanish.  Instead it tries to portray how cities and other man-made artifacts will collapse, in addition to how other lifeforms will adapt.  To illustrate its points, this piece utilizes vivid examples like the crumbling of New York City -- think Will Smith racing the red Camaro through a run-down and overgrown Times Square in  I Am Legend .  This publication has also inspired various TV series like  Life After People  on the History Channel.   Here are some interesting points: 1.    Our houses, built of the usual suspects (wood, clay, bricks), will fall easily to nature.  Their biggest enemy is water that seeps through the smallest cracks, thaws and freezes over time.  Although most roofs are waterproof, water can always find a way to rus

Here is an amazing footage taken by a tourist a few years ago at Kruger National Park in South Africa. A lion pride startled a buffalo herd, attacked and grabbed a calf near shore, only to be surprised by a sneaky crocodile. A tug of war then ensued and the lions claimed victory over the croc. However, the victors soon found themselves losers as the buffalo herd returned, fought off the lions and rescued the calf!  A whole show was produced by Nat Geo Wild based on this short film!  Here are some key points from the experts in the show: 1. Had the leading buffalo stood its ground, the lions might not have charged because the buffalo had numbers.  By turning and running, the herd immediately became prey. 2. The lions were well positioned nonetheless and attacked from three angles. 3. The lions tried to kill the calf by suffocating it. One lion bit its trachea, another its nostrils, but they did not get the job done. 4. The 600-pound croc battled against four 300-pound lions.

Happy New Year! This is my first post in 2010, after a brief hiatus celebrating year end festivities. Apart from watching the magnificent NYE fireworks in Sydney, I managed to do some sightseeing in Canberra and stumbled into the Canberra Deep Space Communication Complex (CDSCC). This place was a godsend as I have always had a deep obsession in astronomy. The CDSCC is part of NASA's Deep Space Network (DSN) and only one of three facilities around the world. The other two are in Goldstone, California and Madrid, Spain. There are four giant radio antennas in this complex.  Each are referred to by a "Deep Space Station" or DSS number. These "dishes" are enormous. The largest one, DSS-43, is 70m in diameter, and is a whopping 23 stories tall when standing on one end. It is the biggest of its kind in the Southern Hemisphere. Owing to high security, i.e. fences,  I could not get a close-up shot to do its monstrous size justice. Operating 24/7, the antennas provid

Here is a short clip on the known universe from the American Museum of Natural History. Starting from Earth zooming out to the solar system, the Milky Way, all the way to the outer frontiers of space that human technology can possibly detect.... and finally back to Earth! -PTS

This article  holds a rare strong argument on the creationist view of life.  It attempts to show us that  not enough time has elapsed from the birth of the universe to allow for all the necessary trial and error in spontaneously creating and then mutating life to where we are today .  Though well written, there is one fatal flaw with its primary argument.  The probability argument does not stand, because to beat it, all you need to do is to be "lucky." I will admit that in our case, we need to be really lucky. Despite the seemingly improbable odds however, it is still possible that one hits the jackpot on the first try.  Just look at the lottery, there is almost always a winner.  And we happen to be one of many lucky winners over time! -PTS

Back in August, I wanted to do a deep dive on the origin of life. Well, my hectic 9 - 5 delayed this exercise by four months. Anyway, I started off by reading  The God Delusion , a bestseller written by the famous Richard Dawkins . This book not only defends atheism, but it goes so far as to attack the religious position. Here are some of the main principles explained: The God Hypothesis - Dawkins contends that if god really created life, then who created god in the first place? He goes on to remind us that the whole problem we started with was to explain the statistical improbability on the origin of life. Thus it makes no sense to take the god position because there is the larger problem of who designed the designer. In comparison, evolution by natural selection becomes a more probable and hence preferrable theory. Evolution of complex organs is possible - creationists argue that complex organs like the eye could not have evolved in a piecemeal fashion over time. This is be

This year marks the 150th anniversary of the publishing of Darwin's On the Origin of Species . It is great that we humans have made it this far in the evolutionary journey. Where will we go from here?    Prediction 1 - Humans Cease to Evolve One condition for evolution to occur is the isolation of a species for beneficial mutations to become norms. In today's ever-shrinking world however, it is hard to find isolated human populations. Instead, cross-breeding over geographic distances is the norm. Thus Darwin's evolution machine has clogged and will eventually come to a complete halt. What is more, the concept of survival of the fittest is being discounted in our species. With medical advances in developed countries, almost everyone can live long enough to produce offsprings. It is not bad news to see people living longer, but don't expect to see X-men any time soon either. Prediction 2 - Humans Continue to Evolve A recent study suggests that due to ovulatory
