Last year, I took a number of vacations which involved cruising, diving, snorkelling and walking on glaciers. Thinking back on those trips, I could not help but notice that water and ice exhibited different colours in different settings. I decided to dive deeper into the colours of water. Finally, here are my findings. Water’s True Colour The colour of an object mainly depends on the colour of light emitted from it. In the case of water its colour is also affected by factors like light source, absorption, scattering, and suspended materials. Absorption by water is stronger for red light, but weaker for blue light. Water is therefore, intrinsically blue. However, this effect is only apparent when the water is reasonably deep. This is why a glass of water appears colourless whereas a big aquarium looks bluish through the thickness of water. Why is the Sea Blue? I did two cruises last year, one in the Caribbean and the other in the South Pacific. Owing to the depth of the wate...
I have long wanted to study Buddhism, because its teachings are quite cryptic in nature and to me, thought provoking. In fact, I took a trip to China's Shaolin Temple in recent weeks to soak in some zen. Shaolin is also known for its Chinese kung fu, so I also signed up for a private martial arts lesson with a warrior monk. That was a great experience in itself, but the story will have to wait for another day. Instead, I wanted to share a great read called Think Like a Monk by Jay Shetty. It portrays a few keystones of Buddhism and how a purposeful life can be led without subccumbing to the distractions we encounter on a daily basis. Reading the book provided an egaging experience as it uses real life examples to illustrate its points. Here is what I learnt: We are what we think people think we are: we often project the "right image" to impress others. This is the direct result of us overthinking our importance in t...
Ever wonder how fresh water is processed and delivered effortlessly into your home? Well for starters, it is not effortless! And, it is definitely not easy. Hong Kong's Water Supply Department (WSD) H2OPE Centre tells it all. It is yet another hidden gem that brings a great wealth of knowledge and interactive fun to your family. If you are visiting the city with young ones, and have a half-day of free time, this is the place to be. The centre covers all key topics one has to know about water. From collection, treatment, distribution, to conservation, you can readily choose content to skim through or deep dive into. Many displays combine visual/audio elements, along with interactive games that captivate your attention, and provide an amusing experience for children. Depending on your interest level, you can spend easily between 1 to 3 hours in the cosy facility. My favourite fun-fact takeaway was that Zebrafish is us...
