This is a list of the Goa'uld characters that appear in "Stargate", "Stargate SG-1", and "Stargate Atlantis".
 In the "Stargate" fictional universe, the Goa'uld are a parasitic alien race that use other beings as hosts.
 Ra had stated in the original "Stargate" film that he had used humans exclusively as hosts for millennia, because Goa'uld technology can repair human bodies so easily that by inhabiting human forms they can be in effect ageless, though they can still be injured or killed.
 Most Goa'uld pose as gods in order to control slave armies, and are considered evil, egocentric megalomaniacs by those who do not worship them.
 The Goa'uld are extremely intelligent and have an aptitude for understanding, working with, and using technology that is superior to that of humans.
 They each have full access to their species' genetic memory from the moment of birth.
 As a result, no Goa'uld has to learn how to operate any technological device; they 'know' how to do so innately.

A positronic brain is a fictional technological device, originally conceived by science fiction writer Isaac Asimov (1920–1992).
 It functions as a central processing unit (CPU) for androids, and, in some unspecified way, provides them with a form of consciousness recognizable to humans.
 When Asimov wrote his first robot stories in 1939 and 1940, the positron was a newly discovered particle, and so the buzz word "positronic" added a contemporary gloss of popular science to the concept.
The Black Sun is a 2005 historical novel by British author James Twining dealing with Nazism and occultism, Die Glocke and stolen Jewish art.
Mindfulness and technology is a movement in research and design, that encourages the user to become aware of the present moment, rather than losing oneself in a technological device.
 This field encompasses multidisciplinary participation between design, psychology, computer science, and religion.
 Mindfulness stems from Buddhist meditation practices and refers to the awareness that arises through paying attention on purpose in the present moment, and non-judgmentally.
 In the field of Human-Computer Interaction, research is being done on "Techno-spirituality" — the study of how technology can facilitate feelings of awe, wonder, transcendence, and mindfulness and on "Slow design", which facilitates self-reflection.
 The excessive use of personal devices, such as smartphones and laptops, can lead to the deterioration of mental and physical health.
 This area focuses on redesigning and creating technology to improve the wellbeing of its users.
