  • The planet Dune is special, because only there Spice, the most important chemical in the universe, is found.

    Several noble families and organizations battle to gain control over the Spice.

    —SPOILERS below for parts 1 & 2 of the series—

    One of the families is set up to be murdered, but their young son survives. He is rescued by the planet’s locals.

    These locals are fierce, and they are many.

    —SPOILERS for part 3 & the rest of the books—

    Lead by the noble son, the local people rise up and conquer the universe. The son becomes the new emperor.

    He realizes that the universe – and mankind – is vulnerable because of the single source of Spice. Under the influence of Spice, he sees and enforces a Golden Path, which will eventually ensure mankind’s survival but destroy the empire.





  • Good question. So, perform an experiment: put an ice cube without air bubbles in a glass containing a mixture of ice and cold water. The temperature should become 0°C (just before it freezes), measure it.

    Your hypothesis: ice is heavier than water, so it will sink

    Execute the test several times, preferably 10 times or more. More is better.

    Please share your experiment results. Interesting data to know for each test would include:

    • sequence number of the test
    • temperature of the mixture before and after you put the ice cube in
    • method of ice cube creation
    • volume of the ice cube
    • volume of water/ice mixture
    • depth of the water/ice mixture (should be > size of the ice cube)
    • type of water used (tap, bottled, …)
    • did the ice cube sink
    • if no, what volume of the cube remained above the surface level

    please also share your conclusion.
