Time Lord technology is brilliant, which is unsurprising; the scientists of Gallifrey were second to none. Perhaps the Doctor is slightly biased; they were his people after all, even though he is the last survivor. His race may be extinct, but much of their technology remains, scattered across far off worlds.
The Doctor has in his possession the greatest of all Time Lord technologies, a TARDIS, designed to be bigger on the inside. It’s impressive, but what’s even more ingenious is the miniaturised version. Anything he might need he carries with him; his pockets are bigger on the inside too.
