Finally, Something Good from Global Warming

The words global warming are often frowned upon. Amid the negative press, can this article help turn the tide? Scientists claim that climatic changes due to global warming has seen increased rainfall in parts of the Sahara Desert. More islands of green are beginning to show, especially in the southern borders. In time, these areas can be reclaimed for agricultural activities.

So why the phenomenon? One theory suggests warmer air being able to hold more moisture, which in turn creates more precipitation. However, it is too early to cast your vote. There are other competing climate models that predict decreased rainfall, pointing the finger at global warming. The split is virtually a dead heat.

Hong Kong's Hidden Gems #3 -- Hong Kong News Expo

Image
As Hong Kong is now fully re-opened to travellers, it is time to introduce yet another hidden gem in the city.  Hong Kong News Expo  (HKNE) is located in a unique neighbourhood in Mid-Levels .  It is a multimedia exhibition that showcases the history, evolution and current state of Hong Kong's news media. The establishment features a wide range of interactive exhibits, historical artifacts, and multimedia presentations.  It is a great niche gem for those interested in the news industry and the role it plays in shaping the city.  The exhibition is divided into several sections, each focusing on different aspects of Hong Kong's news media. For instance, one section is dedicated to the history of newspapers in Hong Kong, featuring how they have evolved over the years -- from the early days of colonial rule to the present day.

Another Earthquake in New Zealand

Image
A magnitude-6.3 earthquake today hit Christchurch, New Zealand. Although less powerful than the one that struck in September last year, it is much more devastating. Many buildings in the city were demolished, including its iconic cathedral. The casualty toll currently stands at 63, but is expected to climb above 100 in the next few days. Today's earthquake struck 45km west of the city and is only 5km below the surface. This aftershock is much closer than the quake that registered five months earlier. My condolences to those affected and I hope the city can rebuild from this unfortunate episode! -PTS

Book Review: Beyond Infinity

Image
Geeking out is something I yearn to do from time to time. Having seen a documentary on infinity from Netflix last year, I decided to pick up a book on the topic.  Beyond Infinity , by  Eugenia Cheng , is an excellent guide delving into this mind-boggling notion. In this book, Cheng explores some key aspects of infinity that challenge our intuition and understanding of mathematics: Numbers Numbers Numbers, natural, rational, irrational and real:   Cheng explains that these number sets are infinite in nature but some are "more infinite" than others.  For instance, the set of natural numbers are smaller than its superset of rational numbers, which in turn are smaller than the set of real numbers.  So far so good?  But...  Infinity is but an abstract notion: It certainly is not a number   to which the rules of arithmetics apply: ∞ + 1 = ∞ (addition/subtraction does not apply) 2  ⋅  ∞ = ∞ (neither does multiplication/division) 1/∞ = 0 (in the sense of limits which touches on the f
