The Complete Idiot's Guide to the Science of Everything

“Why are such a lot vegetation eco-friendly? ”

Why doesn’t abdominal acid dissolve the tummy itself? Why are there extra tornados within the Midwest than at the coast? This quantity solutions those questions and over two hundred extra, laying off gentle at the technological know-how in the back of them. As informative because it is pleasing, it addresses each significant department of technological know-how, together with physics, chemistry, biology, geology, meteorology, astronomy, and cosmology. It highlights a number of the colossal rules that assisted in shaping technology as we all know it, and discusses the way forward for technological know-how on the subject of nanotechnology, genetic amendment, molecular drugs, and string theory.

Turning Points: The Nature of Creativity

Turning issues: the character of Creativity discusses theories and strategies targeting a severe idea of highbrow turning issues within the context of serious considering, clinical discovery, and challenge fixing typically. This e-book introduces a singular analytical and experimental procedure that offers not just new methods for retrospective reviews of clinical switch but additionally for characterizing transformative potentials of potential clinical contributions.

Integral Methods in Science and Engineering

"The current book…focuses at the answer of mathematical types from a number of actual domain names, utilizing imperative equipment at the side of approximation schemes. really, its target is to show…research paintings during which integration, in a single shape or one other, is the most investigative software. loads of difficulties are solved in parts equivalent to sturdy mechanics, fluid dynamics, thermoelasticity, plates and shells, liquid crystals, diffusion and diffraction idea, Hamiltonian structures, resonance, nonlinear waves, plasma, flight dynamics and structural networks.

1 Dragon capsule. Courtesy: SpaceX Commercial Orbital Transportation Services (COTS) 21 The SAAs also benefit the agency because, after 50 years of successful missions, LEO is no longer a real frontier but, by making transportation to and from the ISS the responsibility of private companies, NASA can be freed to develop the heavy lifters that will be needed to go to the asteroids and, hopefully, eventually to Mars. With the NASA budget expected to shrink over the next few years, the SAAs are a godsend for the agency because they will allow it to use what money it does get on science programs and exploratory missions.

In most cases, the US taxpayer would probably avoid having to pay for the entire cost of the damage, since US law requires launch services providers such as SpaceX to carry insurance covering precisely these kinds of accidents. Now, imagine a scenario that involved the launching of a nuclear-powered spacecraft. If SpaceX was the launch provider, their legal team would face some unique challenges in determining the scope of potential damage, due to the lasting effects of radioactive contamination in the event of a catastrophe.

TEA is a volatile, highly pyrophoric compound that ignites immediately upon exposure to air. , In a multi-manifested mission, a restart capability allows delivery of separate payloads to different altitudes and inclinations. Merlin variants 41 Industrially, the compound is used as an intermediate in the production of fatty alcohols, which are then converted to detergents. Since TEA is one of the few substances pyrophoric enough to ignite on contact with cryogenic liquid oxygen (LOX), the substance is especially desirable as a rocket-engine igniter.
