there through the characters of a crystal merchant an Englishman and Santiago. The crystal merchant is one who lives in a dream world because he does not go after his personal legend. The Englishman faces reality because he is always reading books and never interacts with others or takes interest in his surroundings. Santiago turns dreams into reality because he goes after his personal legend by going through many obstacles until reaching the endpoint. The Crystal merchant is described when Everett

experimental technique that exploits the fact that X-rays are diffracted by crystals. It is not an imaging technique. X-rays have the proper wavelength (in th Å t ö (i the Ångström range‚ ~10-10 m) t be scattered by the electron cloud of an atom of 10 10 ) to b tt d b th l t l d f t f comparable size. Based on the diffraction pattern obtained from X-ray scattering off the periodic assembly of molecules or atoms in the crystal‚ the electron density can be reconstructed. Additional phase information must

Observations: *Many crystals formed at the bottom of the jar as well as on the string *Thick layer of crystals on the bottom of the jar *More/thicker crystallization around the paper clip area *Equal width/size around the string *Higher altitude of crystals only on the right half of the jar *Slight crust of crystallization on the top solution (along the rim of the jar) *Solution without movement/stiff and very viscose Discussion Questions: 1. Why does the string need to be soaked

Making Rock Candy Question/Hypothesis: How does the presence of seed crystals change the growth rate of rock candy? If you add seed crystals to the rock candy than they will grow faster because molecules will attract faster. Procedure: 1. Cut out 6 pieces of yarn. Two strings one inch‚ two strings two inches‚ and two strings three inches. 2. Soak one measurement of each string in water for five minutes. 3. Squeeze excess water and roll each onto a tablespoon of water. 4.

HISTORY: 1882 Daniel Swarovski (1862-1956) invents a revolutionary machine that allows crystals to be cut more precisely than with existing manual methods. 1895 Daniel Swarovski founds the company in Wattens‚ Tyrol‚ with the vision of bringing joy to people through crystal. His guiding principle is still followed by the company today: “To constantly improve what is good.” 1949 SWAROVSKI OPTIK is founded‚ and goes on to become

water that are used to build up a crystal lattice in some ionic compounds.In copper II sulphate the blue crystals would be impossible without using water molecules to act as ’scaffolding’ within the structure CuSO4.5H2O. When this is heated the water molecules are driven off and the blue crystals become a white powder. As most crystals are made by evaporation from an aqueous solution‚ it makes sense that water molecules can incorporate themselves into the ionic crystal structure. Water‚ after all‚

the time we return to the initial temperature‚ nearly all of the original material has formed crystals‚ which can be removed from the solvent by filtration. Now‚ suppose that the original solid contained small amounts of impurities. These would go into solution as well‚ but since the impurities are present only in small amounts‚ they remain soluble when the temperature is lowered again. Thus‚ the crystals‚ which come out of solution‚ are more pure than the original sample. This is the essence of purification

sugar to the same amount of boiling water and allow it to be cooled‚ than the one with the additional cup of sugar will be the one that grows more crystals. Therefore‚ the hypothesis was correct. The chosen glass to add the pure cane sugar did grow much more crystals at a more rapid pace. The purpose of the experiment is to grow a large amount of crystals on a wooden skewer. Rock candy is a candy made with sugar that to attempt to grow on a wooden skewer. This delicious candy is actually crystallized
