Quality, Entropy, Energy
As we experience life we can see everything we organized ends up in decay. Living things die and return to the atoms they come from. Man made things break and fall apart. The universe such as stars burn out and explode. The universe is expanding and cooling so sometime in the future is will have no light to view it.
Things are subject to entropy especially man made things, this is where engineering comes in. It takes energy to assemble machines and buildings. The engineer calculates the decay depending on the conditions and time they want something to last. Nature has its own laws and probability which manages decay.
Egypt made pyramids last thousands of years but in the south we build buildings that do not even last 50 years. Where is the quality?
