When we measure things, most people are only worried about how accurate, or how close to the actual value, they are. Looking at the process of measurement more carefully, you will see that there is another important consideration: precision. Matt Anticole explains what exactly precision is and how can help us to measure things better.

  1. A recent paper was recently withdrawn based on this issue. Have not got time now to outline why. Nor to watch time video. But the topic is so important I have subscribed and saved to watch later.

  2. Landing something on Mars is more like curving an arrow around a corner and hitting a moving target that's not only spinning but moving horizontally, on top of that you are also spinning and moving while you take the shot.

  3. Mrs Richards: "I paid for a room with a view !"
    Basil: (pointing to the lovely view) "That is Torquay, Madam."
    Mrs Richards: "It's not good enough!"
    Basil: "May I ask what you were expecting to see out of a Torquay hotel bedroom window? Sydney Opera House, perhaps? the Hanging Gardens of Babylon? Herds of wildebeest sweeping majestically past?…"
    Mrs Richards: "Don't be silly! I expect to be able to see the sea!"
    Basil: "You can see the sea, it's over there between the land and the sky."
    Mrs Richards: "I'm not satisfied. But I shall stay. But I expect a reduction."
    Basil: "Why?! Because Krakatoa's not erupting at the moment ?

  4. Precision is more subjective. It is about the person.
    Accuracy is more objective. It is about the result.
    Usually they will cover each other. To reach accuracy you need precision. Or you are very lucky.
    A percise person or method usually results to accuracy. Unless you are in a really bad luck.

  5. Accuracy:closeness of your data to the true value
    Precision: closeness among your measured value
    Keep this in mind and watch the video to see if you got clear enough..

  6. Accuracy: How close you come to the correct result, improves with tools calibrated correctly and you're well trained with.
    Precision: How consistently you can get the same result using the same method, improves with more finely incremented tools, with less estimation.

  7. (1) Either some non-standard approaches to QUANTUM MECHANICS or (2) some pieces of the comparatively new and as if not entirely confirmed CONSTRUCTOR THEORY result in (at least) two EXPERIMENTALLY PROVED SEVERE violations of the law of conservation of energy, which are described in the two links below:
    You can carry out these simple experiments even in your garage or on your kitchentable.
    We (our team) are open to collaboration and joint work.

  8. too bad faucci, his wife, pfizer, and other medical "experts", aren't doing a true study of the mark of the beast. Because if they didn't care about the money and actually care about "saving lives", they would have accurate and precise studies in the virus and vaccines. I just hope sheeple wake up and become people again to overthrow these idiots and get our normal lives back.
