-Thermodynamics-branch of physics dealing with processes and laws governing the transformation of heat into other forms of energy, heat<--->mechanical work.
-Some names of thermo-Rumford, Davy, Carnot, R.J. Meyer, James Joule-Kelvin/Clausis-thermo theory, Gibbs.
-Thermo-study of macroscopic systems-micro systems include mass, velocity, and KE-marco level includes-temp, vol, pressure, thermoconductivity, viscosity, heat capacity.
-Maxwell-1859-distribution of the speed of molecules in a gas. .
-Statistical Mechanics-study of the avg. motion, looks at the distribution an example being Maxwell distrib.
-Kinetic theory-looks at the same thing as the above example but for each molecule per particle, describes the behavior of, and the velocity, mass, mom, KE,-1872 Boltzmann.
-Internal energy of a sys.-system-avg. collection of objects you want to consider, v, pi=mipi, PE, within the sys., internal to the sys. Ignore external factors, motion relative to each other, and the forces between parts of the system.
-3 ways to change internal E-1) add or remove heat, 2) doing work on it or it doing work on something, 3) adding or removing particles that undergo reactions.
-D.O.F. Characteristics-ways to describe a system, the energy, 8 usual d.o.f., translational, rotational, vibrational .
-Brownian Motion- size 1micrometer in liquid,size H20 1nanometer- the particle would jiggle-symmetric distribution- .
-Conduction-heat flow through a material.
-Convection-physical flow through a liquid or gas.
-Radiation-.
-Qin=heat into a system-Eint=3/2NKbT.
-Work-W=F**X-.
-Particle transfer- add 1 particle with an attractive interaction, example-water beading up-due to attractive force causes molecular vibration-.
-First Law of thermo-energy conservation-.
U-is path dependant- Q and W-are path independent-.
-State of a system-specify outcome of exper. or condition-i.e.-2 dice, 1 red, 1 white, 1 trial, throw dice-state= the number on the top of the dice not the sum of the two-.

He decided to position nuclear missiles there to protect Cuba and to balance the nuclear situation as U.S. had missiles in Turkey. ... Dulles was not afraid to threaten nuclear war to get American gains. ... Felt that MR tied hands of leaders to go to nuclear war or surrender. ...
These nominations included: the would-be Foreign Minister, Manouchehr Mottaki, who had continuously been critical of nuclear negotiations with the Europeans and also as Intelligence Minister, Gholam Hossein Mohseni Ejehei, a cleric whom reformist journalists regarded as a rigid opponent of press freedom. ... In a way, the stubbornness of the nuclear enrichment program was a sign of defiance against American hegemony for Iran. ...
Terrorists, for instance, can learn from the Internet a wide variety of details about targets such as transportation facilities, nuclear power plants, public buildings, airports, and ports, and even about counterterrorism measures.They use the Internet to collect intelligence on those targets, especially critical economic nodes, and modern software enables them to study structural weaknesses in facilities as well as predict the cascading failure effect of attacking certain systems. ... Bombmaking information is literally at the fingertips of anyone with access to a home computer equipped wi...
He decided to go to England and study with J.J. ... Scientists from all around the world came to study with Bohr. ... Meanwhile, he kept working actively for the control of nuclear weapons. ... Bohr and other theorists used this principle to guide them in their work. ... Nonetheless, he was aware of the long-term consequences of nuclear weapons. ...
The purpose of my study is to learn and educate myself about my major ahead of time so I find it uncomplicated in the feature. ...

"When you talk to generals and admirals today, you won't run into one who wants to bring back the draft" states Eliot Cohen, a professor of strategic studies at John Hopkins' Nitze School of Advanced International Studies (Sands, paragraph 10-11). ... It is believed that they are trying to develop biological, nuclear, and chemical weapons. ... In 1991's Desert Storm, precision-guided munitions accounted for 7% of bombs used. ... Most Pentagon officials state they believe that 100% of precision-guided munitions would be used in the opening days of a war with Iraq (Thompson, par...
He quarantines himself in his studies and disregards all else, becoming distant from the outside world. ... Victor states that with more research it may be possible for the subjects of the study to retain their memories and their identity post procedure, as opposed to the original subject who had no recollection of himself or language after re-animation (Chapter 5). This has huge potential to benefit society where the mind and body of great thinkers or leaders can be preserved for an extended period and continue to enlighten or guide humanity. A figure that comes to mind is Stephen Hawking, wh...
Military a) Missile Guidance System b) Laser Sights c) Nuclear Warheads IX. ... Scientists use lasers to study the structure of atoms and molecules. ... These systems currently need someone close to the target with a laser beam to point at the target to guide the missile to it. ... The laser is instrumental in the making of nuclear warheads. ... The laser has affected so many different fields of work and most (except for the nuclear warheads) have been positive. ...
Niels Bohr was a Danish physicist who made many contributions to nuclear physics and the understanding of the atomic structure. ... In March 1912, Bohr moved to Manchester, England, where he joined Ernest Rutherford and his group in studying the structure of the atom. ... Rutherford's nuclear model was unstable, until Bohr introduced the quantum theory. ... Bohr's work was guided by a principle that said that every transition process between stationary states could be coordinated with a corresponding component in the motion of the electrons. ...
