Odic force

Odic force is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Odic force rather than just read about it. In short: Odic force (also called Od , Odyle, Önd, Odes, Odylic, Odyllic, or Odems) was a hypothetical vital energy or life force believed in by some in the mid-19th century. The name was coined by Baron Carl von Reichenbach in 1845 in reference to the Germanic god Odin.

Key takeaways

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

Reference excerpt

Odic force (also called Od , Odyle, Önd, Odes, Odylic, Odyllic, or Odems) was a hypothetical vital energy or life force believed in by some in the mid-19th century. The name was coined by Baron Carl von Reichenbach in 1845 in reference to the Germanic god Odin.

History As von Reichenbach was investigating the manner in which the human nervous system could be affected by various substances, he conceived the existence of a new force allied to electricity, magnetism, and heat, a force which he thought was radiated by most substances, and to the influence of which different people are variously sensitive. He named this vitalist concept Odic force. Proponents say that Odic force permeates all plants, animals, and humans. Believers in Odic force said that it was visible in total darkness as colored auras surrounding living things, crystals, and magnets, but that viewing it required hours first spent in total darkness, and only very sensitive people had the ability to see it. They also said that it resembles the Asian concepts prana and qi. However, they regarded the Odic force as not associated with breath (like India's prana and the qi of Chinese martial arts) but rather mainly with biological electromagnetic fields. Von Reichenbach did not tie Odic force into other vitalist theories. Baron von Reichenbach expounded the concept of Odic force in detail in a book-length article, Researches on Magnetism, Electricity, Heat and Light in their Relations to Vital Forces, which appeared in a special issue of a respected scientific journal, Annalen der Chemie und Physik. He said that (1) the Odic force had a positive and negative flux, and a light and dark side; (2) individuals could forcefully "emanate" it, particularly from the hands, mouth, and forehead; and (3) the Odic force had many possible applications. The Odic force was conjectured to explain the phenomenon of hypnotism. In Britain, impetus was given to this view of the subject following the translation of Reichenbach's Researches by William Gregory, professor of chemistry at the University of Edinburgh. These later researches tried to show many of the Odic phenomena to be of the same nature as those described previously by Franz Mesmer and even long before Mesmer by Emanuel Swedenborg. The French parapsychologists Hippolyte Baraduc and Albert de Rochas were influenced by the concept of the Odic force. Von Reichenbach hoped to develop scientific proof for a universal life force; however, his experiments relied on perceptions reported by individuals who claimed to be "sensitive", as he himself could not observe any of the reported phenomena. The "sensitives" had to work in total or near-total darkness to be able to observe the phenomena. Reichenbach stated that, through experimentation, possibly one-third of the population could view the phenomenon, but far less otherwise.

Scientific reception The concept of Odic force was criticized by the scientific community as there was no reliable or replicable data for its existence. It was described as quackery by critics and is regarded today as an example of pseudoscience. Science writer Martin Gardner in his book Fads and Fallacies in the Name of Science (1957) noted that "scientists were unable to duplicate the baron's experiments." Robert Todd Carroll in The Skeptic's Dictionary has written:

The baron had no training in psychology or psychopathology and no training in devising experiments involving people. He applied many standard scientific techniques and followed standard practices of data collection and recording, including graphs and charts. But he seems to have had no sense of how to do a controlled experiment with so-called "sensitives," people who might better be described as neurotics or delusional. (Jastrow says that for the most part, his subjects were "neurotic young women.") Given the fact that he deceived himself so thoroughly over such a long period of time, it seems reasonable to assume that he was (at the very least) unconsciously suggesting behaviors to his subjects. His enthusiasm for the project undoubtedly biased his subjective observations. That he came to think that the odic force could explain dozens of disparate phenomena, while being unable to convince other scientists that he had discovered anything, signifies the pathological nature of his investigations. Reichenbach's pursuit of the odic force is a classic example of pathological science. Scientists have abandoned concepts such as the Odic force. In western popular culture the name is used in a similar way to qi or prana to refer to spiritual energies or the vital force associated with living things. In Europe, the Odic force has been mentioned in books on dowsing, for example.

Worked examples

Example 1 — a first encounter with Odic force

Start with the simplest possible case. Write down what Odic force 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 Odic force 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 Odic force 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 Odic force

In research
Odic force 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 Odic force 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
Odic force is common in secondary-school and first-year university syllabi. It links to neighbouring topics Consciousness–matter dualism, Energy (esotericism), Hypnosis, so understanding it makes those chapters shorter.
In everyday life
Look for Odic force 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.

Frequently asked questions

What is Odic force in simple terms?

Odic force (also called Od , Odyle, Önd, Odes, Odylic, Odyllic, or Odems) was a hypothetical vital energy or life force believed in by some in the mid-19th century. The name was coined by Baron Carl von Reichenbach in 1845 in reference to the Germanic god Odin.

Why does Odic force matter?

Because it connects several physics ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Odic force?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
