What is the oldest recorded Kingdom in the Malaysian peninsula?

This is the 2nd quiz question I ran on my Facebook page. A few got it right.

Well the answer is Langkasuka which covered Kedah and parts of Patani (now in Thailand).

Historians believe the kingdom to have been founded around 1-2 AD. That's about 1400 years before the Malacca Sultanate.

Records of Langkasuka was found in the Book of Liang (Liáng Shū) compiled by a Yao Silian from the Chinese Liang Dynasty (502-557).

Archologists also refer to Kedah Tua to a civilization that existed in Kedah, which may be related to Langkasuka. Besides the famous ruins in the Bujang Valley, archeologists are now slowly uncovering relics from this ancient civilizations including ships and other amazing stuff.

However, not much is known about this civilization. In fact, not many Malaysians know that the Bujang Valley complex was declared as the home of the oldest civilization in South-East Asia.

Name the only Malaysian state which was once ruled by a Queen?

Many of my Malaysian friends are quite surprised when they find out that I know so many obscure fact about Malaysia even though I was not born here. So I thought it would be a great idea to share what I know about this beautiful country by asking you a Quiz about Malaysia regularly. This was my first quiz on my Facebook page.

The answer is Kelantan. It was the only place in Malaysia to ever have a Queen as a ruler - Cik Siti Wan Kembang. Here is a pic.
Also, Kelantan is the only place in Malaysia where the King was killed by his wife in anger. Puteri Saadong who was the adopted daughter of Cik Siti Wan Kembang, killed her husband Raja Abdullah with her hair pin, for not keeping his promise.

Sorry, I do not have a higher resolution image. Please let me know if have one.

Q&A series: is gold magnetic?

First in the series of questions that came to my head and possibly the answers.

I found out that pure gold is not magnetic - does not stick to a magnet either. If someone gives you an item which they say is gold and it sticks to a magnet, it is probably iron or some other ferromagnetic metal (iron, nickel, cobalt).

However, remember that besides Gold, platinum, silver, lead and aluminium does not stick to a magnet as well.
