Catastrophe theory studies dynamical systems that describe the evolution [5] of a state variable over time : ˙ = = (,) In the above equation, is referred to as the potential function, and is often a vector or a scalar which parameterise the potential function.
For example, some unicellular organisms have genomes much larger than that of humans. Cole's paradox: Even a tiny fecundity advantage of one additional offspring would favor the evolution of semelparity. Gray's paradox: Despite their relatively small muscle mass, dolphins can swim at high speeds and obtain large accelerations.
In geology, catastrophism is the theory that the Earth has largely been shaped by sudden, short-lived, violent events, possibly worldwide in scope. [1] This contrasts with uniformitarianism (sometimes called gradualism ), according to which slow incremental changes, such as erosion , brought about all the Earth's geological features.
A positive check is any event or circumstance that shortens the human life span. The primary examples of this are war, plague and famine. [31] However, poor health and economic conditions are also considered instances of positive checks. [32] When these lead to high rates of premature death, the result is termed a Malthusian catastrophe.
A biotechnology catastrophe may be caused by accidentally releasing a genetically engineered organism from controlled environments, by the planned release of such an organism which then turns out to have unforeseen and catastrophic interactions with essential natural or agro-ecosystems, or by intentional usage of biological agents in biological ...
Sacrifices of “sun stones” occurred around the same time a volcanic eruption in 2900 BC dimmed the sun throughout Northern Europe, according to a new study.

A decade later, with AI more prevalent than ever, Professor Bostrom has decided to explore what will happen if things go right; if AI is beneficial and succeeds in improving our lives without ...
