  2. Mandala - Wikipedia

    en.wikipedia.org/wiki/Mandala

    The Taima mandala is based on the Contemplation Sutra, but other similar mandalas have been made subsequently. Unlike mandalas used in Vajrayana Buddhism, it is not used as an object of meditation or for esoteric ritual. Instead, it provides a visual representation of the Pure Land texts, and is used as a teaching aid.

    Resonance made visible with black seeds on a harpsichord soundboard Cornstarch and water solution under the influence of sine wave vibration A demonstration of sand forming cymatic patterns on a metal plate. Cymatics (from Ancient Greek: κῦμα, romanized: kŷma, lit. 'wave') is a subset of modal vibrational phenomena.

    en.wikipedia.org/wiki/Sand_mandala

    Sand mandala (Tibetan: དཀྱིལ་འཁོར།, Wylie: dkyil 'khor, THL kyinkhor; Chinese: 沙壇城/壇城沙畫) is a Tibetan Buddhist tradition involving the creation and destruction of mandalas made from colored sand.

  5. Electromagnetic absorption by water - Wikipedia

    Water vapor concentration for this gas mixture is 0.4%. Water vapor is a greenhouse gas in the Earth's atmosphere, responsible for 70% of the known absorption of incoming sunlight, particularly in the infrared region, and about 60% of the atmospheric absorption of thermal radiation by the Earth known as the greenhouse effect. [25]

  6. Patterns in nature - Wikipedia

    Waves are disturbances that carry energy as they move. Mechanical waves propagate through a medium – air or water, making it oscillate as they pass by. [68] Wind waves are sea surface waves that create the characteristic chaotic pattern of any large body of water, though their statistical behaviour can be predicted with wind wave models. [69]

    Normally about 12–18 inches (300–460 mm) in length, they taper to a fine point and are made with varying diameter holes at the end in order to disperse the sand in a controlled way. A Tibetan monk will usually tap glide a piece of wood over the ridges in order to slowly allow the sand to emerge through the hole through the vibrations created.

    The Mandala of the Two Realms (Traditional Chinese: 両界曼荼羅; Pinyin: Liǎngjiè màntúluó; Rōmaji: Ryōkai mandara), also known as the Mandala of the Two Divisions (Traditional Chinese: 両部曼荼羅; Pinyin: Liǎngbù màntúluó; Rōmaji: Ryōbu mandara), is a set of two mandalas depicting both the Five Wisdom Buddhas of the Diamond Realm as well as the Five Wisdom Kings of the ...

  9. Ripple tank - Wikipedia

    en.wikipedia.org/wiki/Ripple_tank

    The speed of a wave in water depends on the depth, so the ripples slow down as they pass over the glass. This causes the wavelength to decrease. If the junction between the deep and shallow water is at an angle to the wavefront, the waves will refract. In the diagram above, the waves can be seen to bend towards the normal.
