Article: Search university and college job boards for available positions. Apply for research or teaching positions if you have a Ph.D. and a couple fellowships under your belt. Also let your former professors know that you are looking for a job. They may have information about schools who are seeking candidates for open positions. If you only have a master's degree, then apply for professor-in-residence or visiting professor positions in fields such as geology, chemistry, applied math, atmospheric science, and engineering. Public or private technology-based companies typically hire astrophysicists as technicians or technical staff members. Search for jobs at technology-based companies such as Apple, Raytheon, IBM, Microsoft, Intel, Google, Oracle, and Cisco Systems. Because astrophysicists have advanced data analysis skills, financial firms often hire them to do market modeling. These jobs involve analyzing data in order to predict financial markets. Search for jobs at the World Bank, MasterCard, ING, Goldman Sachs, GE Capital, and Standard Chartered Bank, to name a few. These agencies typically hire astrophysicists with Ph.D.s and master's degrees as technicians for satellite development, space programs, Exo-planet research, and galactic and stellar observations. Look for these jobs at national observatories like Magdalena Ridge, Arecibo, or the Argentine Institute of Radio Observatory. Also look for these jobs at agencies like the Jet Propulsion Laboratory, NASA, and Keck Telescope.

Problem: Article: Look for the main volume control on the bottom right side of the mixer, which is usually labeled "Main Mix" or something similar. The faders are knobs or sliders that control the volumes of individual inputs found along the bottom of the mixer and are either knobs or sliders. If the controls are knobs, turn them counterclockwise until they don't go any further. If the controls are sliders, pull them down as far as you can to lower the volume. If you turn on the mixer without turning the volume and faders down, you could create loud feedback or damage the mixer. The main volume control and faders usually have a different color than the other controls so you can easily tell them apart. XLR cables are used to plug microphones in, and the ends have 3 pins inside a metal cylinder. Your mixer will either have XLR ports along the top edge or on the back side of the mixer. Plug the end of the XLR cable into the microphone you're using. Put the other end of the XLR cable in one of the ports on the mixer that has 3 small holes inside a circle The number above the port determines the input channel, which is a column on your mixer with knobs that controls that single input. You can buy XLR cables from a music supply store or online. The number of inputs you can have on your mixer depends on how many channels it has. An 8-channel mixer can have up to 8 different inputs while a 32-channel mixer can have 32 sources. The line inputs on your mixer are found near the XLR ports for each channel and fit 6.35 mm audio jacks. Plug the end of your audio cable into the instrument you're hooking up. Then choose a channel on your mixer that doesn't have another cable attached to it, and attach the other end of the audio cable to the line input. The number above the input tells you which channel controls the audio for the instrument. You cannot plug an instrument into a line input on a channel that already has an XLR cable plugged into it. You can also buy audio cables for instruments that attach to a mixer with an XLR cable. Either will work for your audio. TRS cables are a balanced audio source, meaning you'll get less feedback and noise from your inputs, and they look like 6.35 mm headphone jacks on the end. Locate the master output ports near the top of the mixer or on the side by the other ports. Plug one of the cables into the port labeled "L" and a second cable in the port labeled "R." Run the cables to your audio interface and plug them into the matching input ports on the back of the interface. You can get an audio interface and TRS cables online or from a music store. Interfaces allow you to play the audio from your mixer through speaker monitors or on a computer. Listening to your mixer through headphones allows you to hear the levels clearly so you can tweak them later on. Use a 6.35 mm headphone jack to plug in your headphones to the mixer. Make sure the headphone cord doesn't tangle around any of the knobs. You don't need to use headphones if you don't want to. The power switch is usually on the back of the mixer or on the top right by the other knobs. Check that all of the volume and fader controls are still turned down before flipping the switch to turn it on. You will see a light turn on as soon as the power is connected. Some mixers may have a switch labeled "phantom" which supplies electricity to microphones that require it. If you have a microphone that uses phantom power, also turn on the switch.
Summary: Turn the master volume and channel faders down completely. Plug microphones into channels using XLR cables. Attach instruments to the line inputs on your mixer. Connect the mixer output to an audio interface with TRS cables to use monitors. Plug headphones into the "Phones" port on the mixer. Turn on your mixer using the power switch.

If your vehicle was built prior to 1996, you will need an OBD I scanner. Vehicles made after 1996 will need an OBD II scanner. Connect the code scanner to the port beneath the dashboard and turn it on. Once connected, use the scanner to bring up the error codes making the check engine light come on. In some code scanners, it will provide the English description of the error code on the read out. If your code scanner does not, you will need to look up the code the scanner shows you to find out what it is. Insert the key into the ignition and start the engine. Wait a minute for the engine idle to level off, then use a pen and paper to write down the RPMs that your engine settles and idles at. You may need to let the engine run for a few minutes in order for it to come down to its normal idle speed. Keep the paper you write the RPMs on handy so you can compare it to the engine's idle as you continue the test. With the idle RPMs noted, shut the vehicle back off and remove the key from the ignition. Open the hood and locate the Idle Control Motor. Once you locate it, disconnect it. The way to disconnect your Idle Control Motor will vary from application to application; refer to your vehicle's service manual for more specific instruction as to how to disconnect it. You can usually disconnect the idle control motor by unplugging the wiring clip going into it. With the Idle Control Motor disconnected, get back into the vehicle and start the engine again. The engine should still start and run without any issue despite the idle control motor being disconnected. Be sure to tuck the wiring you disconnected up in the engine bay so it doesn't get caught in any moving parts. Allow the engine to run for a minute so it settles to a consistent idle, then take note of any difference in the idle RPMs versus the idle you observed earlier. If the idle has not changed at all, it's likely because your idle control motor has not been functioning. If the idle control motor was working, disconnecting it should have created a difference in the engine's idle. This test confirms there's an issue with the idle control motor, but not what the issue may be. If you identified a difference in engine idle RPMs with the Idle control motor connected and disconnected, confirm your hypothesis by reconnecting it and starting the engine again. The idle should go back to what it was when the idle control motor was last connected. Refer to the note you took about idle RPMs to compare it to your first reading.
