Classical unified field theories Classical unified field theories Since the 19th century, some physicists, notably Albert Einstein, have attempted to develop a single theoretical framework that can account for all the fundamental forces of nature – a unified field theory. Classical unified field theories are attempts to create a unified field theory based on classical physics. In particular, unification of gravitation and electromagnetism was actively pursued by several physicists and mathematicians in the years between the two World Wars. This work spurred the purely mathematical development of differential geometry. This article describes various attempts at formulating a classical (non-quantum), relativistic unified field theory.

Unified Task Force Unified Task Force The Unified Task Force (UNITAF) was a US-led, United Nations-sanctioned multinational force, which operated in Somalia between . A United States initiative (code-named Operation Restore Hope), UNITAF was charged with carrying out United Nations Security Council Resolution 794 to create a protected environment for conducting humanitarian operations in the southern half of the country. After the killing of several Pakistani peacekeepers, the Security Council changed UNITAF's mandate issuing the Resolution 837 that establishes that UNITAF troops could use "all necessary measures" to guarantee the delivery of humanitarian aid in accordance to Chapter VII of the United Nations
