The Life Cycles of Stars In the universe‚ there are hundreds of billions of stars. They are formed when gas and dust from space "clump" together. As the mass grows larger‚ gravity takes over and a core begins to form. The core becomes extremely dense and this compaction causes temperatures within it to rise to the point where nuclear fusion (the burning of hydrogen in a chain reaction) can begin. The heat generated by fusion can reach 24 million degrees F (Fahrenheit). "That amount of heat keeps

the core as a gaseous shell. The gas that surrounds the core is called a "Planetary Nebula". The core that is left then becomes a "white dwarf". After the white dwarf cools down enough it stops shining and dies‚ forming a "black dwarf". Another life cycle of a star involves a star with a mass of 10 solar masses or more. These stars evolve similarly to stars of about 1 solar mass until they reach "main sequence". The star shines bright until all of its hydrogen has fused to form helium. This takes

Are iPads and tablets bad for young children? Tablet ownership has more than doubled in the past few years – and as many parents are finding‚ children are highly proficient at using them. But are these devices harmful to their development? Or do they encourage ’technological intelligence’? Paula Cocozza The Guardian‚ Wednesday 8 January 2014 12.59 EST Meet the experts: children often find tablets more instinctive than adults.

Eventually though a passing star or shock wave from a supernova will disturb the gas and dust. The dust and gas may then start to clump together‚ gravity will then clump more and more gas together‚ this is when the star starts the next part of its life cycle. Protostar: A protostar is when the gas has clumped together and it getting hot but has not reached what is known as critical mass. At this point the gas will be hot enough to glow. but since there is still a large amount of dust su

George MOLDOVEANU Academ de Studii Economice din Bucureşti Abstract This paper proposes an analogy between rational biological model and the organizations’ development during their existence. So‚ organizations’ "born" or creation are considered the result of genetic algorithms‚ transformations are identified with changes that aim the adapting to the environment‚ and finally the ”death” treats the state of

episode of “60 minutes” that discusses autistics. In the episode‚ autistics who were thought to be unintelligent were proved to be as smart as normal kids their age through apps on the iPad. The problem wasn’t that the autistic weren’t intelligent; it was that they had no way to communicate their thoughts. The iPads kept them focused and they could easily communicate by tapping the buttons that corresponded with what they wanted to say. The author then tells us that she has Asperger’s Syndrome herself

Case study notes This case has been updated to include the Apple iPad. Principally this is case explores the issue of licensing and how successful firms can become unsuccessful. It is not a case about Apple and why it has become successful. This case study explores the rise of the Apple Corporation. The Apple iPod is one of the most successful new product launches in recent years‚ transforming the way the public listens to music‚ with huge ramifications for major record labels. More than 50 million

first time the school had faced the problem of inappropriate use of iPads‚ which were provided to students by STS. The students were taking advantage of the fact‚ that the school’s method of teaching was paperless; they were abusing the features of the technology by sharing answers during exams and cyber bulling. One of the main components of the iPads is the Air Drop feature‚ which is made to share the information between Apple Products. Air Drop allows users simultaneously and synchronously send files

LIFE CYCLE OF A STAR Stars are formed in nebulae‚ interstellar clouds of dust and gas (mostly hydrogen). These stellar nurseries are abundant in the arms of spiral galaxies. In these stellar nurseries‚ dense parts of these clouds undergo gravitational collapse and compress to form a rotating gas globule. The globule is cooled by emitting radio waves and infrared radiation. It is compressed by gravitational forces and also by shock waves of pressure from supernova or the hot gas released
