    en.wikipedia.org/wiki/Programming_and_Meta...

    Programming and Metaprogramming in the Human Biocomputer: Theory and Experiments is a 1968 book by John C. Lilly. In the book, "the doctor imagines the brain as a piece of computer technology." [1] More specifically, he uses "the analogy of brain being the hardware, the mind being the software and consciousness being beyond both." [2]

  4. Human brain - Wikipedia

    en.wikipedia.org/wiki/Human_brain

    The adult human brain weighs on average about 1.2–1.4 kg (2.6–3.1 lb) which is about 2% of the total body weight, [2] [3] with a volume of around 1260 cm 3 in men and 1130 cm 3 in women. [4] There is substantial individual variation, [ 4 ] with the standard reference range for men being 1,180–1,620 g (2.60–3.57 lb) [ 5 ] and for women ...

  5. Brain size - Wikipedia

    en.wikipedia.org/wiki/Brain_size

    The size of the brain is a frequent topic of study within the fields of anatomy, biological anthropology, animal science and evolution.Measuring brain size and cranial capacity is relevant both to humans and other animals, and can be done by weight or volume via MRI scans, by skull volume, or by neuroimaging intelligence testing.

    en.wikipedia.org/wiki/Biological_computing

    The invention was the final of the three components necessary to build a fully functional computer: data storage, information transmission, and a basic system of logic. [ 8 ] Parallel biological computing with networks, where bio-agent movement corresponds to arithmetical addition was demonstrated in 2016 on a SUBSET SUM instance with 8 ...

  7. Central processing unit - Wikipedia

    en.wikipedia.org/wiki/Central_processing_unit

    A CPU cache [71] is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. A cache is a smaller, faster memory, closer to a processor core , which stores copies of the data from frequently used main memory locations .

  8. List of human-based units of measurement - Wikipedia

    en.wikipedia.org/wiki/List_of_human-based_units...

    This is a list of units of measurement based on human body parts or the attributes and abilities of humans (anthropometric units). It does not include derived units further unless they are also themselves human-based. These units are thus considered to be human scale and anthropocentric.

  9. Air displacement plethysmography - Wikipedia

    en.wikipedia.org/wiki/Air_Displacement_Plethysmo...

    Air displacement plethysmography (ADP, also known as whole-body air displacement plethysmography) is a recognized and scientifically validated densitometric method to measure human body composition. ADP is based on the same principles as the gold standard method of hydrostatic weighing , but through a densitometric technique that uses air ...
