Spontaneous glass breakage is a phenomenon by which tempered glass may spontaneously break without any apparent reason. The most common causes are: [13] [14] Internal defects within the glass such as nickel sulfide inclusions. Nickel sulfide defects can cause spontaneous breakage of tempered glass years after its manufacturing. [15]
The adult glasswing butterfly can be identified by its transparent wings with opaque, dark brown borders tinted with red or orange. Their bodies are a dark brown color. The butterflies are 2.8 to 3.0 centimetres (1.1 to 1.2 in) long and have a wingspan of 5.6 to 6.1 centimetres (2.2 to 2.4 in).
Wings may have evolved from appendages on the sides of existing limbs, which already had nerves, joints, and muscles used for other purposes. These may initially have been used for sailing on water, or to slow the rate of descent when gliding. Two insect groups, the dragonflies and the mayflies, have flight muscles attached directly to the ...
The butterfly isn't just an elegant emblem in Ree's world. In Greek mythology, psyche (which means "soul" or "butterfly") is often depicted with butterfly wings. Butterflies are thus connected to ...
M. confusa and M. curvifascia have similar larval appearances. M. confusa has 12 stripes on the body while M. curvifascia has 11. [5] M. confusa as an instar has dark brown and yellow stripes transversely across the body. As a pupa, it has a black cremaster and the wing pads have a black and gold color a couple days before emerging as an adult. [5]
The flapping wing represents a small change in the initial condition of the system, which causes a chain of events that prevents the predictability of large-scale phenomena. Had the butterfly not flapped its wings, the trajectory of the overall system could have been vastly different.
This neotropical butterfly is found in Central and South America, including the Cerrado which is a vast tropical savanna in Brazil. [5] Other locations include Mexico [2] and Venezuela. [6] Ancestors of the Morpho menelaus butterfly may have been distributed in the Andean regions. [4] Morpho menelaus is one of the six species of Morpho in Costa ...
The Virginia junior rewrote the record books in the women's 100-yard butterfly, blowing the rest of the competition out of the water with a 47.42-second finish. The next-fastest was Emma Sticklen ...
