The idea of kinetic art is getting a bit of a workout at the moment. MIT Museum recently hosted “year of kinetic art‚ including “5000 Moving Parts‚” a kinetic art exhibiton featuring large-scale works by Arthur Ganson‚ Anne Lilly‚ Rafael Lozano-Hemmer and John Douglas Powers. Plus the Kinetic Art Organization has published a digital “International Collection of Essays About Kinetic Art—2013—volume 1.” The two don’t overlap: The MIT show highlights a somewhat different segment of artists working

Hydrogen Summary * This is how hydrogen fuel cells work: 1. Gas stored in tanks 2. Atoms reach anode 3. Become hydrogen ion and a free electron 4. Ion goes through electrolyte layer 5. Hydrogen ion passes‚ but free electron does not 6. Free electron runs through external circuit from anode (-) to cathode (+) 7. Current of electrons creates electricity 8. Hydrogen ion enters cathode and combines with oxygen to become water which is better for the ecosystem because

In this essay I’m going to give a brief history of the hydrogen bomb‚ the chemistry behind the bomb‚ and how much destruction the hydrogen bomb can do. After the Soviet Union’s atomic bomb success during the cold war‚ the U.S wanted something bigger and stronger. In 1950‚ President Harry S. Truman announced work on the hydrogen bomb. A group of scientists led by Edward Teller created the first hydrogen bomb in

Functional Decomposition Diagram An analyst first must understand an organization’s business functions before he or she can begin developing information systems. The functional decomposition diagram (FDD) is a business planning tool that depicts the hierarchy of business functions‚ processes‚ and subprocesses within an organization that are later described in detail using process models (chapter 6). The exercise of breaking down‚ or decomposing‚ the business functions into processes makes complex

But I think it happened because the blow dryer only focuses on one point so it doesn’t effect the other vanes. When I used the power of wind‚ I realized that the result was so much

Looking back at the research question‚ the actual amount of reactant did not match the theoretical stoichiometric amounts according to the balanced equation‚ but the amount of catalyst matched the original value when uncertainty is taken into account. The percent yields for the reactants in the equation are very far from 100% yield. In the case of water‚ the percent yield came out to be meaning there were at least 2 times to 4 times more water than there should be. The percent yield of oxygen came

Dry friction is also subdivided into static friction between non-moving surfaces‚ and kinetic friction (sometimes called sliding friction or dynamic friction) between moving surfaces. * Lubricated friction or fluid friction resists relative lateral motion of two solid surfaces separated by a layer of gas or liquid. * Fluid friction
