Israeli contributions to science and technology have been significant. Since the establishment of the State of Israel, Israel has worked in science and engineering. Israeli scientists have contributed in the areas of genetics, medicine, agriculture, computer sciences, electronics, optics, engineering and other high-tech industries.

Israeli science is particularly well known for its military technology, from simple submachine guns like the Uzi, ranging to advanced anti-ballistic defense systems - like the Arrow. Moreover, Israel is among the small group of nations in the world that have the capability to launch satellites into orbit (the others include the USA, Russia, China, Japan, India, and some European nations through the ESA).

As a dry land, Israel has pioneered in advanced agricultural technology such as water-conserving irrigation methods, salinity research, enriched compost, irrigation, and enhanced genetic engineered crops. Dry lands which have peace with Israel have received aid from and/or collaborated with Israeli experts in order to improve desert agriculture and produce more food. Israel has a world-wide reputation in this area.

Israel also has a high reputation in theoretical physics. Israeli physicists tend to deal more with theoretical and conceptual aspects of physics, especially in questions of time and space, and the paradoxes and strange phenomena of quantum mechanics.

Israel is also known for its well-developed and revolutionary medicine. Israel medical researchers and surgeons have worldwide reputation, in searching for new cures as well in high technology and reliability. Recently, a group of researchers from the Weizmann Institute developed a molecular biocomputer that may help cure cancer.
