Product Information

A variation of self replication is of practical relevance in compiler construction, where a similar bootstrapping problem occurs as in natural self replication. A compiler ( phenotype) can be applied on the compiler's own source code ( genotype) producing the compiler itself. During compiler development, a modified ( mutated) source is used to create the next generation of the compiler. This process differs from natural self-replication in that the process is directed by an engineer, not by the subject itself. The U.S. should take a lesson from Ukraine to innovate and deploy technology fast or potentially miss the boat, according to several witnesses at a House Armed Services subcommittee hearing on the Defense Department’s Replicator program, which aims to scale drones within the next two years.

In 2004, Robert Freitas and Ralph Merkle published the first comprehensive review of the field of self-replication, in their book Kinematic Self-Replicating Machines, which includes 3000+ literature references.

One form of natural self-replication that isn't based on DNA or RNA occurs in clay crystals. [11] Clay consists of a large number of small crystals, and clay is an environment that promotes crystal growth. Crystals consist of a regular lattice of atoms and are able to grow if e.g. placed in a water solution containing the crystal components; automatically arranging atoms at the crystal boundary into the crystalline form. Crystals may have irregularities where the regular atomic structure is broken, and when crystals grow, these irregularities may propagate, creating a form of self-replication of crystal irregularities. Because these irregularities may affect the probability of a crystal breaking apart to form new crystals, crystals with such irregularities could even be considered to undergo evolutionary development.Kemeny, John G.

Eric Drexler's 1986 book Engines of Creation. [7] Replicators aboard Starfleet vessels would not produce fatal poisons. ( VOY: " Death Wish") Furthermore, replicators had biofilters which automatically screened out all contaminants. ( DS9: " Babel") Although clothing could be replicated for general wear, they would not allow non-Starfleet crewmembers to replicate official Starfleet uniforms. ( VOY: " Caretaker") They produced synthehol versions of alcoholic drinks by default, but they could easily be manually readjusted through their control panel to make real alcohol instead.

A more speculative, more complex microchip fabricator was specified to produce the computer and electronic systems, but the designers also said that it might prove practical to ship the chips from Earth as if they were "vitamins."

Replicator technology, even if produced on a larger scale, had not been able to be used to create complex objects such as shuttlecraft or starships (the production staff felt that being able to replicate entire starships "at the push of a button" would severely impact dramatic potential). However, in the Star Trek: Deep Space Nine episode "For the Cause", industrial replicators are used to replicate large components of ships, shuttlecraft, and other pieces of this sort, which are later used in shipyards to construct such vessels. In this manner, as few as 15 industrial replicators are enough to replicate the components needed to build a fleet of starships or to help a civilization recover from a planet-wide natural disaster. Starfleet's safety protocols prevent unauthorized replication of dangerous objects, such as weapons and poisonous substances.

When the USS Voyager was pulled to the Delta Quadrant, it became clear that replicator technology was unknown to some of the indigenous peoples of that region.
