Corona discharge the electron-liberation is a high-energy photon from an atom within the plasma body relaxing after excitation from an earlier collision. The use of ionized neutral gas as a source of ionization is further diminished in a negative corona by the high-concentration of positive ions clustering around the curved electrode. Under other conditions, the collision of the positive species with the curved electrode can also cause electron liberation. The difference, then, between positive and negative coronas, in the matter of the generation of secondary electron avalanches, is that in a positive corona they are generated by the gas surrounding the plasma
Negative and positive atheism Negative and positive atheism Negative atheism, also called weak atheism and soft atheism, is any type of atheism where a person does not believe in the existence of any deities but does not explicitly assert that there are none. Positive atheism, also called strong atheism and hard atheism, is the form of atheism that additionally asserts that no deities exist. The terms "negative atheism" and "positive atheism" were used by Antony Flew in 1976 and have appeared in George H. Smith's and Michael Martin's writings since 1990. Because of flexibility in the term "god", it is possible that a person
