    A rose or rhodonea curve is a sinusoid plotted in polar coordinates. These curves can all be expressed by a polar equation of the form: r = cos(kθ) If k is an integer, the curve will be rose-shaped with: -2k petals if k is even -k petals if k is odd

    The joy of in high latitudes. We can learn so much about the beauty and dynamics of these regions from satellite imagery. But we need complementary microwave radiometry to see through clouds is being developed for this purpose see

    A solid ring will be caught by a loop of chain if it tumbles during its fall. By Newton's Third law, when the ring twists into and hits the chain, the impact transfers momentum to the end of the chain, which rises up and over the ring
