Theory of everything differ both from gravity and from electromagnetism. A further hurdle was the acceptance that in a TOE, quantum mechanics had to be incorporated from the start, rather than emerging as a consequence of a deterministic unified theory, as Einstein had hoped. Gravity and electromagnetism could always peacefully coexist as entries in a list of classical forces, but for many years it seemed that gravity could not even be incorporated into the quantum framework, let alone unified with the other fundamental forces. For this reason, work on unification, for much of the twentieth century, focused on understanding the three "quantum" forces:
Unified Patents Unified Patents Unified Patents is a member-based organization whose goal is reducing the number of non-practicing entity (NPE) assertions in specific technology areas. Instances of NPE patent litigation have grown recently: NPEs (commonly referred to as patent trolls) accounted for the majority of patent infringement litigation in the U.S. in 2012, compared to less than a quarter in 2007. This is because NPEs can achieve a quick return on investment since most companies settle rather than fight, even if they believe the assertion to be invalid. Unified permits small and large companies alike to become members. Smaller members act as
