Red Cloud

(noun)

A war leader and a chief of the Oglala Lakota (Sioux). He led as a chief from 1868 to 1909. One of the most capable Native American opponents the U.S. Army faced, he led a successful campaign in 1866–1868 known as "Red Cloud's War" over control of the Powder River Country in northeastern Wyoming and southern Montana.

  • Aurora Borealis and the Aurora Australis

    • Clouds in the sky and any light (natural sunlight or man-made light) can prevent the possibility of seeing the aurora from the ground.
    • Oxygen emissions are green or brownish-red, depending on the amount of energy absorbed.
    • Oxygen is unusual in terms of its return to ground state: it can take three-quarters of a second to emit green light and up to two minutes to emit red.
    • This is why there is a color differential with altitude: at high altitudes, oxygen's red emissions remain; then, oxygen's green emissions and nitrogen's blue and red emissions; and finally, only nitrogen's blue and red emissions are left, because collisions prevent oxygen from emitting any light at all.
    • Green is the most common color of all auroras, followed by pink, a mixture of light green and red, pure red, yellow (a mixture of red and green), and pure blue.
  • Atomic Radius

    • The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the nucleus to the boundary of the surrounding cloud of electrons.
    • Red numbers are ionic radii of cations, black numbers are for neutral species, and blue numbers are for anions.
  • The Decorative Arts under the Ming Dynasty

    • A Ming Dynasty red lacquer box with intricate carving of people in the countryside, surrounded by a floral border design.
    • A blue and white porcelain vase with cloud and dragon designs, marked with the word "Longevity," Jiajing period of Ming Dynasty
  • Types of outliers in linear regression

    • Outliers in regression are observations that fall far from the "cloud" of points.
    • (3) There is one point far away from the cloud, and this outlier appears to pull the least squares line up on the right; examine how the line around the primary cloud doesn't appear to fit very well.
    • (4) There is a primary cloud and then a small secondary cloud of four outliers.
    • There might be an interesting explanation for the dual clouds, which is something that could be investigated.
    • You will probably find that there is some trend in the main clouds of (3) and (4).
  • The Human Toll

    • Drought and massive wind storms that threw up giant clouds of dust continued throughout the 1930s, leading to the period being called “the Dirty Thirties.”
    • In 1934, an estimated 75% of the United States felt some effect from the storms, including New England, where red snow fell.
    • As the 1930s progressed, the soil continued to dry, turn to dust and blow eastward and southward in large, dark clouds.
    • At times, these clouds blackened the sky, reaching all the way to East Coast cities such as New York and Washington, D.C.
  • Electrolytic Properties

    • As a result, a negative charge cloud develops in the electrolyte around the cathode, and a positive charge develops around the anode.
    • Two mnemonics for remembering that reduction happens at the cathode and oxidation at the anode are: "Red Cat" (reduction - cathode) and "An Ox" (anode - oxidation).
    • Chlorine gas on the other hand is much more likely to be reduced under normal conditions, as can be inferred from the value of $E_{red}^0 (V)$= +1.36 V in the table.
  • Introduction

  • Metallic Crystals

    • The solid produced is held together by electrostatic interactions between the ions and the electron cloud.
    • Because outer electrons are less affected, blue-light absorption is increased, resulting in enhanced reflection of yellow and red light.
