Thomas Hector Schofield, nicknamed Hex, is a fictional character played by Philip Olivier in a series of audio plays produced by Big Finish Productions based on the long-running British science fiction television series Doctor Who. A staff nurse working for St. Gart's Hospital in London in the year 2021, he is a companion of the Seventh Doctor.
Hex first appeared in the play The Harvest (2004), where he met the Doctor and Ace while the two were investigating signs of alien activity at St. Gart's. Ace was going by her real name of McShane and working in Human Resources, striking up a conversation with Hex to gain information on the mysterious C-programme. When Hex gave Ace a ride to her "lodgings" in Shoreditch, he spied her going into a police box at Totter's Lane. Since Hex was hammering on the door and demanding to know what was going on, Ace let him inside the TARDIS, and Hex's world was transformed forever.
Hex aided the Doctor and Ace in their investigations at St. Gart's, uncovering the latest invasion scheme of the Cybermen and helping the time travellers defeat their old foes. At the adventure's conclusion, Hex asked if he could accompany them in their travels. The Doctor accepted him as his newest companion.
PiHKAL: A Chemical Love Story is a book by Dr. Alexander Shulgin and Ann Shulgin which was published in 1991. The subject of the work is psychoactive phenethylamine chemical derivatives, notably those that act as psychedelics and/or empathogen-entactogens. The main title is an acronym that stands for "Phenethylamines i Have Known And Loved".
The book is arranged into two parts, the first part being a fictionalized autobiography of the couple and the second part describing 179 different psychedelic compounds (most of which Shulgin discovered himself), including detailed synthesis instructions, bioassays, dosages, and other commentary.
The second part was made freely available by Shulgin on Erowid.org while the first part is available only in the printed text. While the reactions described are beyond the ability of people with a basic chemistry education, some tend to emphasize techniques that do not require difficult to obtain chemicals. Notable among these are the use of mercury-aluminum amalgam (an unusual but easy way to obtain reagent) as a reducing agent and detailed suggestions on legal plant sources of important drug precursors such as safrole.
