History
Studying paths of evolution of technical systems has been a primary research method of TRIZ since its inception. But until the 1970s the discovered recurrent patterns of evolution were not consolidated into a separate section of TRIZ and were scattered among other sections. In the 1970s Altshuller consolidated them into a new section of TRIZ that he called "the laws of technical systems evolution". It included both previously discovered recurrent patterns of evolution and newly discovered ones. Studying "laws of evolution" became an independent research topic in TRIZ. The following authors, besides Altshuller, contributed most to it: Yuri Khotimlyansky (studied patterns of energy conductivity in technical systems), Vladimir Asinovsky (proposed principles of correspondence of various components of technical systems), Yevgeny Karasik (co-authored with Altshuller the law of transition from a macro-level to a micro-level, introduced the notion of dual technical systems and studied the patterns of their evolution).

Famous quotes containing the word history:
“It gives me the greatest pleasure to say, as I do from the bottom of my heart, that never in the history of the country, in any crisis and under any conditions, have our Jewish fellow citizens failed to live up to the highest standards of citizenship and patriotism.”
—William Howard Taft (1857–1930)
“The History of the world is not the theatre of happiness. Periods of happiness are blank pages in it, for they are periods of harmony—periods when the antithesis is in abeyance.”
