Pseudo-medicine, a placebo, ineffective.

Homeopathy is very expensive water. (full marks on the mid-term, any other materially different answer gets zero).

Homework: go to http://www.randi.org/site/

  1. -The purpose of the organization is to promote rational and critical thinking as well as fighting with pseudoscientific and paranormal claims.

    -James Randi is a retired magician, founder of the James Randi Educational Foundation. He calls himself an “investigator”, for years studying the paranormal, supernatural etc. and debunking it along the way.

    -“In chemistry and physics, the Avogadro constant is defined as the number of constituent particles (usually atoms or molecules) in one mole of a given substance. It has dimensions of reciprocal mol and its value is equal to 6.02214129(27)×1023 mol−1” –NO IDEA WHAT THIS MEANS

  2. Sceptical articles.

    "Mission statement:

    Our mission is to promote critical thinking by reaching out to the public and media with reliable information about paranormal and supernatural ideas so widespread in our society today."

    "James Randi has an international reputation as a magician and escape artist, but today he is best known as the world's most tireless investigator and demystifier of paranormal and pseudoscientific claims."

    "Avogadro’s limit basically says you can only dilute so far before you lose the original substance altogether. The standard homeopathic dilution, advocated by the founder of homeopathy for most purposes, is not 3X, not 6X, not 10X, but 60X or 1 in 1060, an absurdly big number. A 60X dilution is supposed to mean a concentration of 1 part per:

    1,000,000,000,000,000,000,000,000,000,000,
    000,000,000,000,000,000,000,000,000,000,
    000,000,000,000,000

    But this is chemically impossible."

    - the number of particles (eg, molecules, atoms, ions, electrons) in one mole of any substance: Avogadro's number equals 6.022137 · 1023 mol-1.

  5. -The purpose of this organization is promotion of critical thinking about paranormal and supernatural ideas.
    -James Randi was used to be known as a magician and escape artist, but he forfited deciving people and started organizaton promoting critical thinking against, so called, magic.
    -Avogadro's limit is constant numerical value equal to quantity of substance's atoms or molecules in mole of this substance.

  6. -Purpose of the website is to expose out the silliness that some people pass off as real as well as promoting rationality and critical pondering (the word 'thinking' was getting stale), in a similar vein, the show Bullshit (featuring the mighty Penn Jillete, and his silent minion, Teller) does it in a lighthearted way, some of the episodes are NSFW

    -James Randi is a former magician and escape artist who is on the warpath against pseudo-science. And apparently there was a program on 'Nova' about his investigations of Uri Geller, the problem, THEY DIDN'T PUT THE NAME IN.

    -Avogadro's limit is the SMALLEST amount of molecules of a substance that can still be considered that substance. In layman's terms, if you spill a drop of orange juice in the ocean, it's still the bloody ocean and not an orange juice ocean.
