  3. Hypothetical types of biochemistry - Wikipedia

    en.wikipedia.org/wiki/Hypothetical_types_of...

    The possibility of life-forms being based on "alternative" biochemistries is the topic of an ongoing scientific discussion, informed by what is known about extraterrestrial environments and about the chemical behaviour of various elements and compounds. It is of interest in synthetic biology and is also a common subject in science fiction.

  4. Germanium - Wikipedia

    en.wikipedia.org/wiki/Germanium

    Germanium is a chemical element; it has symbol Ge and atomic number 32. It is lustrous, hard-brittle, grayish-white and similar in appearance to silicon. It is a metalloid (more rarely considered a metal) in the carbon group that is chemically similar to its group neighbors silicon and tin. Like silicon, germanium naturally reacts and forms ...

  5. Materials science in science fiction - Wikipedia

    en.wikipedia.org/wiki/Materials_science_in...

    Materials science in science fiction is the study of how materials science is portrayed in works of science fiction. The accuracy of the materials science portrayed spans a wide range – sometimes it is an extrapolation of existing technology, sometimes it is a physically realistic portrayal of a far-out technology, and sometimes it is simply a plot device that looks scientific, but has no ...

  6. List of existing technologies predicted in science fiction

    en.wikipedia.org/wiki/List_of_existing...

    This list of existing technologies predicted in science fiction includes every medium, mainly literature and film. In 1964 Soviet engineer and writer Genrikh Altshuller made the first attempt to catalogue science fiction technologies of the time. Alongside first prediction of a particular technology, the list may include all subsequent works mentioning it until its invention. The list includes ...

  7. Isotopes of germanium - Wikipedia

    en.wikipedia.org/wiki/Isotopes_of_germanium

    Germanium (32 Ge) has five naturally occurring isotopes, 70 Ge, 72 Ge, 73 Ge, 74 Ge, and 76 Ge. Of these, 76 Ge is very slightly radioactive, decaying by double beta decay with a half-life of 1.78 × 10 21 years [4] (130 billion times the age of the universe). Stable 74 Ge is the most common isotope, having a natural abundance of approximately ...

    en.wikipedia.org/wiki/Protector_(novel)

    Protector is a 1973 science fiction novel by American writer Larry Niven, set in his Known Space universe. It was nominated for the Hugo in 1974, and placed fourth in the annual Locus poll for that year. [1] The work fleshes out a species called the Pak, originally introduced in a 1967 story called "The Adults", which forms the first half of the novel (there titled Phssthpok); the second half ...

  9. Germanium compounds - Wikipedia

    en.wikipedia.org/wiki/Germanium_compounds

    Germanium compounds are chemical compounds formed by the element germanium (Ge). Germanium is insoluble in dilute acids and alkalis but dissolves slowly in hot concentrated sulfuric and nitric acids and reacts violently with molten alkalis to produce germanates ([GeO. ).
