Key takeaways

  • Harold E. Puthoff belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Harold E. Puthoff to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Harold E. Puthoff from memory before moving on to harder problems.

Reference excerpt

Harold Edward Puthoff (born June 20, 1936), often known as Hal Puthoff, is an American electrical engineer and parapsychologist known for his work in laser physics, remote viewing research, and theories on zero-point energy.

Early life and career Puthoff was born in Chicago, Illinois. He received a BA and an MSc in electrical engineering from University of Florida. In 1967, Puthoff earned a Ph.D. in electrical engineering from Stanford University with a thesis, "The stimulated Raman effect and its application as a tunable laser". Puthoff then worked on tunable lasers and electron beam devices and co-authored (with R. Pantell) Fundamentals of Quantum Electronics (Wiley, 1969). Puthoff also published papers on polarizable vacuum (PV) and stochastic electrodynamics.

Parapsychology and pseudoscience

Puthoff took an interest in the Church of Scientology in the late 1960s and reached what was then the top OT VII level by 1971. Puthoff wrote up his "wins" for a Scientology publication, claiming to have achieved "remote viewing" abilities (called exteriorization in Scientology). In 1974, Puthoff also wrote a piece for Scientology's Celebrity magazine, stating that Scientology had given him "a feeling of absolute fearlessness". Puthoff severed all connection with Scientology in the late 1970s. In the 1970s and 1980s, Puthoff directed a program at the Stanford Research Institute (SRI) to investigate paranormal abilities, collaborating with Russell Targ in a study of the purported psychic abilities of Uri Geller, Ingo Swann, Pat Price, Joseph McMoneagle and others, as part of what they called the Stargate Project. Both Geller and Swann convinced Puthoff and Targ that they possessed psychic powers, though Geller employed sleight of hand tricks. Puthoff and Targ studied Uri Geller at SRI, declaring that Geller had psychic powers, though there were flaws with the controls in the experiments, and Geller used sleight of hand on many other occasions. According to Terence Hines:

Geller turned out to be nothing more than a magician using sleight of hand and considerable personal charm to fool his admirers. The tests at SRI turned out to have been run under conditions that can best be described as chaotic. Few limits were placed on Geller's behavior, and he was more or less in control of the procedures used to test him. Further, the results of the tests were incorrectly reported in Targ and Puthoff's Nature paper. Psychologists David Marks and Richard Kammann attempted to replicate Puthoff and Targ's remote viewing experiments. In a series of thirty-five studies, they could not replicate the results. While investigating the procedure of the original experiments, Marks and Kammann discovered that the notes given to the judges in Puthoff and Targ's experiments contained clues as to which order they were carried out. Examples included referring to yesterday's two targets or the inclusion of the date of the session written at the top of the page. They concluded that these clues were the reason for the experiment's high hit rates. Terence Hines has written:

Examination of the few actual transcripts published by Targ and Puthoff show that just such clues were present. To find out if the unpublished transcripts contained cues, Marks and Kammann wrote to Targ and Puthoff requesting copies. It is almost unheard of for a scientist to refuse to provide his data for independent examination when asked, but Targ and Puthoff consistently refused to allow Marks and Kammann to see copies of the transcripts. Marks and Kammann were, however, able to obtain copies of the transcripts from the judge who used them. The transcripts were found to contain a wealth of cues. Marks noted that when the cues were eliminated the results fell to a chance level. James Randi noted that controlled tests by several other researchers, eliminating several sources of cueing and extraneous evidence present in the original tests, produced negative results. Students also solved Puthoff and Targ's locations from the clues that had inadvertently been included in the transcripts. Marks and Kamman concluded: "Until remote viewing can be confirmed in conditions which prevent sensory cueing the conclusions of Targ and Puthoff remain an unsubstantiated hypothesis." According to Martin Gardner, Puthoff (and Targ) "imagined they could do research in parapsychology but instead dealt with 'psychics' who were cleverer than they were".

Business ventures In 1985, Puthoff founded The Institute for Advanced Studies at Austin (IASA), later incorporated under EarthTech International, Inc., in 1991, which pursues energy generation and propulsion research. Puthoff and EarthTech were granted a US Patent in 1998, with claims that information could be transmitted through a distance using a modulated potential with no electric or magnetic field components. While "the invention does appear to rest on solid, albeit somewhat obscure, physics principles", the case is used for educational purposes in patent law where "the examiner failed to make a prima facie case for inoperability or lack of enablement". According to the Wisconsin Law School case study, "The lesson of the Puthoff patent is that in a world where both types of patents are more and more common, even a competent examiner may fail to distinguish innovation from pseudoscience." In 2017, he co-founded the UFO-dedicated company To the Stars with Tom DeLonge.

Worked examples

Example 1 — a first encounter with Harold E. Puthoff

Start with the simplest possible case. Write down what Harold E. Puthoff claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Harold E. Puthoff before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Harold E. Puthoff ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Harold E. Puthoff

In research
Harold E. Puthoff appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Harold E. Puthoff in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Harold E. Puthoff is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1936 births, 20th-century American engineers, 21st-century American physicists, so understanding it makes those chapters shorter.
In everyday life
Look for Harold E. Puthoff outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
