Lee Kuan Yew: Singapore’s Founding Father and First Prime Minister – No More With Us

Singapore, 23 March, (

Lee Kuan Yew, the Founding Father and First Prime Minister of Singapore who transformed that tiny island outpost into one of the wealthiest and least corrupt countries in Asia, died on Monday morning. He was 91.

Lee Kuan Yew, who founded modern Singapore and was both feared for his authoritarian tactics and admired for turning the city-state into one of the world’s richest nations, died Monday,

“The Prime Minister is deeply grieved to announce the passing of Mr. Lee Kuan Yew, the founding prime minister of Singapore,” a statement posted on the Prime Minister’s official website said. “Mr. Lee passed away peacefully at the Singapore General Hospital today at 3:18 am.”

Mr. Lee Kuan Yew was Prime Minister from 1959, when Singapore gained full Self-Government from the British, until 1990, when he stepped down. Late into his life he remained the dominant personality and driving force in what he called a First World oasis in a Third World region.

Lee was admitted to Singapore General Hospital on Feb. 5 for severe pneumonia and was later put on life support.
The country’s first and longest-serving prime minister, Lee guided Singapore through a traumatic split with Malaysia in 1965 and helped transform what was then a sleepy port city into a global trade and finance centre.

Although he could have remained in office for much longer, he stepped aside and handed over leadership of the ruling party, and the country, to a younger generation in 1990. Still, he remained an influential behind-the-scenes figure for many more years until his health deteriorated. Read more of this post

Math Trick – Multiply Using Lines!

SINCE THE BIRTH OF THE ALPHABET in the Near East around 2000 BC, endless writing systems from different languages and cultures have thrived and perished. The classic example is Egyptian, a highly developed civilization whose legacy remains the form of a famous hieroglyphic writing system…which we’ve never been able to fully decipher.

Over the last 2,500 years, the Latin alphabet has become so popular it’s swept away writing systems of peoples once dominated by the Romans. However, more than two billion people still write in other formats, and a few of them display an impressive handmade beauty.

Below are five of the most aesthetically attractive alphabets in the world, and the reasons why you’re probably never going to read them.

1. Burmese (Myanmar)

The Burmese alphabet (from old Burma, now called Myanmar) is composed of circular shapes that must always be drawn clockwise. The mesmerizing script has a raison d’êtremore practical than aesthetic: The palm leaves in which the letters were traditionally carved were easily torn by straight cuts.

Even if it’s less threatened than other alphabets on this list, the Burmese script is more and more often being relegated to liturgies while, in daily usage, it’s being replaced by Hindi and even Latin writing systems. Myanmar, which until recently restricted foreign tourism, has just opened its borders to visitors, and left the exclusive group of nations where you couldn’t spot a Coca-Cola billboard (leaving only North Korea and, arguably, Cuba).

2. Sinhalese (Sri Lanka)

Considered one of the most expansive alphabets in the world, Sinhalese has more than 50 phonemes, though only 38 are frequently used in contemporary writing. Still taught in Buddhist monasteries and schools, the language is the mother tongue for more than half of Sri Lanka’s 21 million inhabitants.

Its low geographical relevance (confined to the island of Sri Lanka) is its greatest threat. Restricted to a piece of land surrounded by water, Sinhalese writing has will likely endure for a good while yet, even if its usage decreases over time. Read more of this post


An ovitrap is a device which consists of a black cylinder with a piece of cardboard submerged into the water in the cup. Ovitraps mimic the preferred breeding site for container breeding mosquitoes, including Aedes albopictus and Aedes aegypti.

The Ovitrap was first described in 1966[1] and was initially designed for monitoring Aedes populations. Researchers found that if they provided artificial breeding sites, they could easily collect and study the eggs found in the container. Since the original ovitrap was invented, lethal ovitraps have been developed, which kill the larvae and/or the adult mosquitoes that enter.

Ovitraps used for monitoring can detect Aedes mosquito populations thus acting as an early warning signal to preempt any impending dengue outbreaks.[2] Analysis can be done on the ovitrap breeding data collected weekly to identify mosquito breeding hotspots and risk areas when there is a danger of high Aedes infestation. This analysis is used to plan vector surveillance and control operations.

The extensive use of the ovitrap in a community can be used in Aedes population control and effectively reduce the Aedes population in that area. It has been used in countries like Singapore, United States and Hong Kong since the 1970s.
