Back in the day, the two argue, alchemy was not the misguided pseudoscience that most people think it was. If two of the greatest scientists who ever lived were dedicated alchemists, then alchemy needs a makeover, a big one, contend Principe and his colleague William Newman, a historian of science at Indiana University. As it turns out, Boyle was a devotee of alchemy too. The recipe for the Philosophers’ Stone had come from his older contemporary, the famed British chemist Robert Boyle. Newton was not the only intellectual heavyweight from his era trying to make gold. Newton’s dabblings in alchemy are well known, but his belief that he had found the closely guarded blueprint for the Philosophers’ Stone was astonishing indeed. Today revered as the father of modern physics and the inventor of calculus, Newton was describing a recipe for the Philosophers’ Stone, a legendary substance that reputedly could turn base metals like iron and lead into gold. Holding the yellowed manuscript in his hands and studying the scribbled words, he understood that he was looking at one of the best-kept secrets in the history of science. Any Newton manuscript is of interest, but this one was worth its weight in gold, literally - as Principe, a chemist and historian of science at Johns Hopkins University, recognized immediately. For any question do not hesitate to contact your INT SA, Instrument Specialist or INT Manager.Lawrence Principe was sorting through a collection of old chemistry books at the Chemical Heritage Foundation in Philadelphia when he stumbled upon a forgotten manuscript handwritten by Sir Isaac Newton.

In WINTER time, before arriving to the telescope, read the recommendations and advices about Ice Safety. Please read carefully the information about filling the WFC or IDS cryostat. Please read through the Emergency Procedures for Visiting Astronomers, and if you have any doubt about it ask your INT SA. WFC programmes in the new scheme of INT Service-mode observations. PIs of regular proposals at INT now have the possibility to request service observations for their IDS or Service mode observations for regular INT programmes Please contact your INT SA to coordinate this. Observers with little (or long ago) experience at INT are encouraged to spend the previous night to the start of their run at the telescope. The SA will be at the telescope from the afternoon until about midnight of the first day of the run and will be reachable at ORM Residencia during the whole first night of the run. Health and safety documentation prior to the starting of the observing run.Īs there is no Telescope Operator (TO) at the INT, observers are responsibleįor all aspects of telescope and instrument operation during the night.Ī detailed introduction to the telescope and instrument is given by the INT Support Astronomers (SA), who will contact the PI in advance, to confirm the instrument configuration, discuss the observing plan, etc. Visiting observers at INT should have considerable end-to-end observing experience with medium-sized telescopes and be familiarized with the instrument, telescope and
