Carnot Principle:
The maximum efficiency of a real cycle is the efficiency of a Carnot cycle operating over the same temperatures

Work
- work
- Force acting through a distance
Energy
- Energy
- Capacity to do work
- Internal Energy
- The total energy of the system[1]
Heat
- Heat
- Energy transferred due to a temperature difference
- Adiabatic
- No heat transfer between a system and its surroundings
- Exothermic process
- A process which releases heat
- Endothermic process
- A process which adsorbs heat
- Pressure
- Force divided by the surface area it is applied to
- SI unit is the Pascal (Pa) = 1 N/m2
- SI unit is the Pascal (Pa) = 1 N/m2
- SI unit is the Pascal (Pa) = 1 N/m2
- SI unit is the Pascal (Pa) = 1 N/m2
- SI unit is the Pascal (Pa) = 1 N/m2
- SI unit is the Pascal (Pa) = 1 N/m2
Observations
The laws of thermodynamics are based on observations of the natural world. The first law is based on two observations concerning energy:
- Energy can be transferred between a system and its surroundings by only two ways: work and heat
- The total energy of a system and its surroundings is always constant (The conservation of energy)
First Law
These two observations can be combined into the First Law of Thermodynamics:
The internal energy of a system is constant unless changed by doing work or by heating
Computers and Software
I use a computer for almost all of my work. I consider myself to be a power user. By that I mean that I spend a lot of time configuring the computer so that it suits my needs. I am not a really a programmer, even though I do write short scripts in shell language, awk, sed, and recently lisp.
Here is a snapshot of my system:
(colors?)
OS: By now I think you have figured out that I use Linux.
Distribution: Gentoo. This is what is called a source distribution, it builds all its software from source. That has two advantages, all the programs are built for my specific architecture and I can only install the packages I want. (reword?)
Window Manager: Stumpwm (primary), Xmonad, Fluxbox. Notice I do not use KDE or Gnome. I consider them bloated. I prefer a tiled window manager as I find it more productive. I actually prefer Ion, but I do not care for its license.

shell: z shell
text editor (and kitchen sink): Emacs
browser: firefox (+Adblock&NoScript, Zotero), w3m (offline)
