Science Mark is an attempt to put the truth behind benchmarking. In an attempt to model real world demands and performance, SM2 is a suite of high-performance benchmarks that realistically stress system performance without architectural bias.
The benchmarks in wide use today fail to accurately reflect system performance due to the following:
1.Relevance: The benchmarks test only 1 application and dont address a wider array of
applications more representative of the users market.
2.Abstraction: They are entirely comprised of synthetic tasks that dont perform a complex meaningful task.
3.Quality: May be poorly constructed from a C or Fortran perspective and limited in their ability to measure the true potential of a system.
4.Objectivity: The test is developed on or tuned for one architecture resulting in implicit performance bias.
Synthetic benchmarks are useful, and can tell the user valuable performance characteristics about their systems performance, but they should not be used in entirety to measure system performance; this role is reserved in greater part to real applications performing real tasks. Science Mark 2.0 is comprised of 7 benchmarks, each of which measures a different aspect of real world system performance.

Science Data Reference System 2.6 is considered as a comprehensive program which contains a range of data reference tables for Chemistry, Physics and Biology, as well glossaries and a number of calculators and science tools. These include a scientific calculator that can calculate molecular mass, a molar mass calculator, triangle calculator, angle converter, over 60 equation calculators that can solve for any variable in the equation and an extensive measurement converter with over 50 categories. Numerous data reference tables can be quickly called, as well as glossaries and lists of acronyms. The system is easy to use and will readily run from a USB.

Half-Life Science & Industry Mod 0.97 beta is a feature-rich and trustworthy Science & Industry mod which puts you in the role of a security officer in one of two rival research and development firms.

Science and Industry is a team-play mod for Half-Life, in which players assume the role of Security Officer in one of two rival corporations striving for domination in the cutthroat world of chemical and weapons research and development. As security officer, it is your job to acquire and protect your company's most valuable human resources - scientists. Scientists conduct research and develop new products, bringing your company profit.

Conveniently, the products your company's scientists develop take the form of new weapons that you and your fellow security officers can use to pound the other company into submission. Stealing scientists from your rivals is a great way to boost productivity and keep those new weapons coming, but of course your competition has the same tactics in mind. So defending your company's scientists is just as important as 'finding' new ones.
