The man suffering from the unquenchable desire to conquer the world is constantly engaged in the process of rising above others. All the modern technological inventions that we use today have made daily activities easier. With the rapid development of communication and transportation sectors, the entire country has become a global village today.

However, it must be acknowledged that the scientific and technological advancements we have achieved today did not happen overnight, but are the result of human efforts over thousands of years. The facts that reveal the scientific wisdom and technological knowledge of the ancients who lived in the world at that time are visible from all over the world. Current scientists are also surprised by this because they look like cosmic karmic creations. Many artefacts found in archaeological excavations reveal the historical and cultural value of each country to the world.

We all know that there are 383 days in a year. As a way to extend that conclusion, the surprise that scientists have been investigating for a long time is that the Yenes of the pre- Columbian civilization lived a year. The period is calculated as 365 days. The Sasara Passat of the Kuku Church, which has a pyramidal shape, has been used for this calculation.

There is also evidence that the ancients created cities in a more hygienic and orderly manner. The best examples of this are the city designs of Mohendajaro and Harappa civilizations. It is clear that the development of cities and housing at that time was seen not only in the period when dirty water was built so that the house was well ventilated, but also the remains of water pipes that had water even in the houses.

A petrified marvel designed to withstand the desert climate of the Arabian desert. Due to the buildings created in the stone itself, the unique characteristics of the Ghrukani craft of that time are revealed. According to the UNESCO declaration, it is included in the cultural heritage as well as the seven wonders of the world.

Such amazing designs have been found in many other countries of the world, and it is possible to understand how the scientific and technological development of this country was in the past in the ancient buildings of our country. Our old industrial sailors who built sky- spanning dagabs and sea- faring tanks can be called brilliant engineers and scientists.

We have heard on many occasions that the service rendered by our technicians to the tourism industry has surprised today's engineers.

Because it was in Anuradhapura, it is amazing that Jaya Gasa, which supplied water to the lakes, Kandy Lake and Navi Chaduwa, was built with one trench for each comfort. Moreover, under the Mahaweli Development Scheme, when the terrain was selected for the construction of the Maduru Oya Reservoir, the oldest dam was also found there. . Moreover, the kingdom of Sigiriya, which has the greatest archaeological value, has become a world heritage as a royal palace, a fort, a beautiful garden and a temple complex because of the advancement of science and technology that our ancients had at that time.

The power of imagination to observe and imagine a feeling that has arisen in the mind of a Pusiya person creates an object seed that leads to a creation. Self- strength, collateral commitment to reveal it successfully. The designer should have the skill of correct use of technical knowledge as well as restraint, irrepressible courage, and the ability to use technical knowledge correctly.

That is why ninety amazing designs with the above characteristics are found all over the world. Even the above- mentioned creations are the reasons that our ancestors used science and technology knowledge with the intention of using noble inventions for future generations. If so, follow the example of our ancestors and use the science and technology tools available to you in various guises for the good of you and the country and preserve your humanity.
