    Well Isn't That Interesting Thread

    I recently read an article about the approach to computers smarter than humans. One wag suggested that Moore's Law has been holding up for several decades and computers are approaching 1,000 petaflops. What is a petaflop, one might ask. Well it is 10 to the 15th operations per second. Up and down the scale these prefixes go. Let's familiarize ourselves with them, just for fun and edification.

    A milligram is one thousandth of a gram.
    What is one thousandth of a milligram?
    Of course that is a microgram.
    What is a thousandth of a microgram?
    That would be a nanogram.
    What is a thousandth of a nanogram?
    That would be a picogram.
    Does it get any lighter?

    Well, in a word, it most certainly, positively, absolutely, and certainly does.
    A thousandth of a picogram is a femtogram.
    And a thousandth of a femtogram is an attogram, or 10^ -18 grams.
    What about the other direction? I thought you'd never ask.
    1,000 grams is a kilogram.
    Moreover 1,000 hertz is a kilohertz. That's a lot of pain if you ask me, but
    then again, you didn't ask me.
    1,000 kilotons is a megaton, as in equivalents of TNT explosive power.

    Boom, boom.
    1,000 megagrams is a gigagram.
    1,000 gigameters is a terameter.
    1,000 terabaud is a petabaud.
    1,000 petajoules is an exajoule.
    That is a whole lot of joulery.
    1,000 exawatts is a zettawatt, which is 10 * 21 watts.

    From the attogram, 10 to the minus 18, to the zettawatt, 10 to the + 21 watts would be 39 orders of magnitude.
    That is greater by far than the diameter of the universe in feet, which is about 10 to the 28th.
    “The explanation value of the evolutionary hypothesis of common origin is nil! Evolution not only conveys no knowledge, it seems to convey anti-knowledge. How could I work on evolution ten years and learn nothing from it? It does seem that the level of knowledge about evolution is remarkably shallow. We know it ought not be taught in high school, and that’s all we know about it.” (Dr. Colin Patterson, senior Paleontologist at the British Museum of Natural History)

    I have had to measure capacitance in Femto-farads (10^-15). That required me to zero out the fixture used to make the measurement down into the Atto-farads (10^-18). Most capacitance measurements are in picofarads (10^-12).

    Islam is a religion of violence and terror as practiced by the Islamofascists. The Muslims that do speak out against terror are then terrorized by the Islamofascists and are ignored by the Lap Dog Media.

    I can still calculate the capacity of hot water cylinders and the associated pipework of heating systems.

    U B off a bit. A ton is 2000 #, a kiloton. Is 1000 tons or. 20,000,000#
    And a Google is 1x10 100 power a number. so large it is estimated to be greater than all the electrons in the universe.

    When scientists want to be funny, they say a "Michael Moore" instead of a kiloton.

    You KNOW what the diameter of the universe is?

    You mentioned "#", I didn't.
    1,000 kilotons is a megaton.

    Now for more interesting stuff.

    Ah.jpg

    We have all heard of the element of surprise. That got me to thinking about the surprise of elements, the pun and the reality.
    I combined them.

    The surprise of elements is that Nature's God used only three building blocks in ways so mysterious we still cannot understand them.
    Electrons are particles but they are also waves. I am told that but I can't comprehend it. Electrons bear up tall buildings without crushing. The nuclei of all atoms are deep inside and this strange stuff, impossibly tiny, resists enormous pressures in the form of steel, and rocks.
    From ultralight hydrogen to dense, valuable, and beautiful gold, how is it that the panoply of elements has such depth and breadth and utility? How is it that chemical reactions are 100% reversible on the atomic scale, permitting the carbon cycle, the nitrogen cycle, the oxygen cycle, and stability of our oceans, our atmosphere, and life overall? Mercury is a liquid metal. Who would have thought of such an elegant material except Nature's God.

    Metals are superlatively constructed to have great shear strength, tensile strength, electrical and heat conductivity, ductility, and alloyability to name but a few properties. What if there were only a few tons of iron and aluminum and magnesium and zinc and gold and silver on earth, and these few tons were evenly distributed in the soil on all continents? No cars. No aircraft. No computers. No jewelry. No electronics or motors. No fun.

    The more you think about the surprise of elements, the more you have to appreciate the genius of their Creator.
    “As a man who has devoted his whole life to the most clear headed science, to the study of matter, I can tell you as a result of my research about atoms this much: There is no matter as such. All matter originates and exists only by virtue of a force which brings the particle of an atom to vibration and holds this most minute solar system of the atom together. We must assume behind this force the existence of a conscious and intelligent mind.” Max Planck
    “The explanation value of the evolutionary hypothesis of common origin is nil! Evolution not only conveys no knowledge, it seems to convey anti-knowledge. How could I work on evolution ten years and learn nothing from it? It does seem that the level of knowledge about evolution is remarkably shallow. We know it ought not be taught in high school, and that’s all we know about it.” (Dr. Colin Patterson, senior Paleontologist at the British Museum of Natural History)
