The worst offenders might be shampoo adverts, but egregious pseudo-science is not exactly rare in fiction. Joined by The Science Of Fiction regular Djuke Veldhuis, we take a look at what gets scribbled in beside the bits in the script marked “technobabble”.

Minimizing the edit distance from last week's show, Chris Smowton joins us to talk about androids, AI, the uncanny valley, and tiny fire extinguishing robots.

We take a look at reboots, remakes, re-imaginings, and other almost-synonymous new versions of old works. Are they made to take advantage of new technology; to update the plots for modern audiences; or maybe for no valid reason at all?

Needless to say, none of the music featured on this episode was as it was originally recorded:

Kat Arney—songstress, Naked Scientist, knitter—joins Andy and Will to chat about colliders, steampunk, lab-based literature, quacks and the ’Verse.

Fasten your tin-foil hats securely, as Andy and Will delve into the murky world of conspiracy theories. Assassination plots, Martian civilizations, mysterious ionosphere research—and how The Establishment will wipe your memory when you've finished listening.

Andy and Will take a (pseudo-)random walk around the scientific and/or fictional topics suggested by their music collections, from interdimensional transport using gravity pulses to musical trees via whistling at nuclear missiles.

Thomas Truax plays the Hornicator. It is Psapp who built and played the Bone-a-phone.

Djuke, guest star of last season's episode about stress, returns to the show to discuss hybrids, aliens and mutants across fiction and fact (and 16th century Scottish superstition, naturally).

Andy and Will correct their past selves’ on-air blunders, and take a look at shakey science in fiction and fact.

Bond, Neil Stephenson, Turing, and a real live Enigma machine in the studio!

Here are some photos: Andy, James, the Enigma machine, its instructions, and a video of James demonstrating the machine during the episode.

James Grime is the “resident tamed mathematician” of The Enigma Project.

Good Will Hunting, the bat sonar digital switchover, The Hunt for Red October, The Oxford Murders, A Beautiful Mind, Pi, Kevin Bacon, curing the world of Facebook, dinosaurs.

Your archivist believes that one host was struggling to remember the details of the Ramanujan-Hardy number on this episode.
