During the Second Industrial Revolution, the rate of technological progress, commonly defined as productivity, increases and so does the improvements in product quality, which depends much specifically on the smaller, anonymous changes known as micro-inventions . These path-breaking inventions in energy, materials, and almost everything else were important not because they necessarily had a huge impact on production, rather it was because they increased the efficiency of research and development in such aspects.
Because such activities will eventually, like everything else, run into the same problem of diminishing practice and product, these new inventions open up new horizons, and that was the inventions’ impact. In essence, technology is
