Ancient Innovations (3rd Century BC – 12th Century AD)
Ancient Sinhalese civilization is most renowned for its “Hydraulic Civilization,” featuring engineering feats that remained unmatched in the West for nearly 2,000 years.
- Biso Kotuwa (Valve Tower): Invented in the 3rd century BC, this is the ancient equivalent of the modern valve-pit. It allowed for the regulation of water flow from massive reservoirs without the high pressure destroying the embankment.
- Jaya Ganga (Giant Canal): Built by King Dhatusena in the 5th century AD, this 87 km canal maintains an incredible gradient of just 6 inches per mile (1:10,000), a feat of precision surveying that challenges even modern engineers.
- Tank Cascade System (Ellangawa): A sustainable water management network that connected series of small and large tanks to manage silt, toxins, and water distribution, recognized today as a Globally Important Agricultural Heritage System.
- Wind-Powered Steel Production: As early as 300 BC, Sinhalese engineers used monsoon winds to power furnaces, producing high-quality steel exported to the Islamic world for making famous swords.
- World’s First Hospitals: Literary evidence from the 4th century BC during King Pandukabhaya’s reign marks the earliest recorded institutions dedicated specifically to the care of the sick.
Innovations in Cricket
Sri Lanka has played a pivotal role in modernizing the sport through both technological concepts and tactical revolutions.
- Decision Review System (DRS) Concept: The “Player Referral” concept, which is the foundation of the modern DRS, was conceived by Sri Lankan lawyer Senaka Weeraratna to make umpiring fairer.
- ODI Batting Revolution: In the mid-1990s, Sanath Jayasuriya and Romesh Kaluwitharana revolutionized One Day International (ODI) cricket by introducing an aggressive strategy of hitting over the infield during the first 15 overs, a tactic that led to their 1996 World Cup victory and is now a global standard.
- Bowling Techniques: Unique “slinging” actions, such as those of
, were developed through local “beach cricket” and tennis-ball play, influencing modern limited-overs bowling.
Modern Scientific Breakthroughs
Contemporary Sinhalese innovators continue to make significant contributions to global science and medicine.
- Room-Temperature Superconductors:
led a team that discovered the world’s first room-temperature superconductor, a major breakthrough in physics.
- Medical Devices: Recent inventions include a Video-Laryngoscope by
Dr. Anupa Herath
and a Laparoscopic Knot Applicator by
Dr. Thilanka Ratnapala
, both receiving gold medals at international exhibitions.
- Nano-Technology:
Manju Gunawardana
patented the Nano Bulb, which uses nanoparticles to eliminate bacteria and viruses from the air to curb the spread of diseases.
- Mathematical Instruments:
Dinesh Katugampala
invented the world’s first radius meter based on his own “Square Dual Theorem” to measure the radius of any sphere or arc.
