Once you've hauled in your boxes of electronics, clear the entertainment room and lay everything out. Take inventory of what you have, and if you've forgotten something, go back out and get it before you start setting up. Before you plug anything in, place your receiver in front of (or underneath) your TV, then do a walk-through of where you want to place your speakers accordingly. For example, if you have a 5.1 system, consider placing 1 speaker directly in front of your TV, 2 on either side of the TV, and 1 on either side of the seating area. Leave your subwoofer alone for now. Your setup will differ based on how many speakers you have, the layout of your room, and the height of your seating; this is simply a general reference. The 2 speakers on either side of the TV should be placed firmly on the ground or a stand. If you have a larger speaker system, place surplus speakers around or behind the seating area in an arc; this will enhance your surround-sound experience. From a top-down perspective, your front speakers should form an equilateral triangle with the center of your seating placed at the apex. Take the width of your room and the general number of people you hope to seat into account here--your speakers will need to be placed farther apart from one another if you hope to engage each member of a crowded room equally, whereas they can be fairly close together if you're the sole occupant. Surround-sound speakers are best place to the immediate left and right of your seating arrangement, with the speakers elevated to roughly standing ear level. If you don't have enough room to the left and right, you can always mount the speakers behind your viewing area. Once you've determined roughly where everything should go, attach your receiver to your TV and any existing pieces of hardware (consoles, Blu-ray, etc.). You should have a general A/V input (i.e., HDMI cable, optical cable, coaxial cable) to connect your TV to your receiver--this will differ based on your hardware, especially if you have older TV and receiver models. You may want to pull your TV away from the wall while you do this for ease of access. This is where you'll need your speaker cable; though some brands include these cables by default, you're better off buying your own. If you have a system higher than 2.1, plug in your remaining speakers to your receiver using speaker cable. Listen to a DVD or some music that you're familiar with; to figure out how to tweak your speakers' placement, walk around the room and take note of where the audio quality dips or otherwise sounds different than normal, then adjust the speakers accordingly. Pay special attention to sound distortion; this can be especially indicative of poor speaker placement. To avoid distortion, make sure your speakers have plenty of room all around them to broadcast sound--don't place them in a corner or between objects. You may also need to play with your TV's audio settings to even out bass and treble. Since your subwoofer's sound quality will likely change based on the size and shape of your room, there isn't one universal way to place it, so experiment until the sound is balanced and refined. A good rule of thumb with subwoofers is never place them directly against walls or in corners. Even with the right audio adjustments, this can distort your bass. Entertainment systems with limited space usually resort to placing the subwoofer on one side of the TV, facing the seating area but not angled toward the viewer's head height like the other speakers. Walk around the room one final time to ensure your TV's audio is even and balanced throughout, experimenting with different bass settings to eliminate distortion as you go. Remember that your end goal is to distribute the audio equally to everyone in the room; therefore, ensuring that the audio is consistent throughout the seating area should be your top priority.

Summary: Unbox everything and lay it out. Do a dry run. Place your speakers. Plug in your receiver. Plug your front speakers into your receiver. Plug in your other speakers. Turn everything on. Connect your subwoofer. Double check your calibrations.

You can take the same actions at work or school that you'd take at home to reduce water pollution. Look into the policies at your workplace or school and find out if there are changes you could help to facilitate to create a pollution-free environment. Getting classmates, teachers, and coworkers involved is a great way to educate others and make a difference. For example, you could recommend that your office or school switch to eco-friendly cleaning supplies, and make suggestions as to which ones work well. You could also put up signs reminding people to conserve water in the bathroom and kitchen areas. This could include reminders never to leave a sink running longer than necessary and encouraging the men or boys to use urinals rather than toilet stalls. If you live near a local body of water, there's a lot you can do to help reduce pollution there. See if there's a group working to clean up local beaches, lakes, rivers or oceans. Many cities host clean-up days during which volunteers can come help clean up trash to purify local waterways. If you can't find a local group working to reduce water pollution in your area, you might be just the person to start one! Consider hosting a cleanup day. Set a date, publicize the event, and have a plan in place for collecting and disposing of the trash. Corporations that allow industrial waste to seep into waterways are the biggest culprits when it comes to water pollution. There are regulations in place to prevent this from occurring, but it's still a common occurrence. Find out if there's a certain factory or energy plant in your area responsible for polluting local waterways, and speak up about the problem. Learn about local and national laws against water pollution and join up with groups working to protect water in your area. Voting for political candidates who strive to protect waterways is a great way to do your part to reduce pollution.

Summary: Get involved at school and work. Help clean up litter in water-filled areas. Speak up about water issues that affect your community.

You can find a silly GIF to send via chat or post a cute meme on their social media. Humor is a fun way to share an inside joke or a smile even when you aren't together. You don't always have to try to be "romantic" to stay connected. Sharing laughter is a good way to avoid becoming depressed due to being apart. Pictures are a fun way to include each other in daily life and can be sent instantly. They can also help to keep the other person from getting jealous as they are regularly included in daily life. Celebrate the times you are together and countdown to the next time you will visit each other. A slideshow with a special song can be a fun way to save memories. This doesn't need to be something "romantic", instead a sign that you are paying attention and know him better than anyone else. As a special way to count down to an upcoming visit, you can also send special gifts he can use while traveling or for the visit. If he is flying send him a survival kit for the flight or a new scarf in his favorite color for a winter visit.

Summary: Send a funny e-card. Send a silly picture of yourself. Make a slideshow that features photos of you two. Mail him a care package of his favorite things.

The laptop's height is measured with a closed screen. If your laptop slopes when closed, measure the thickest part. Laptops aren't usually taller than two inches. If you need to know the height in centimeters but only have the inches measurement, multiply the inches by 2.54 to find the measurement in centimeters. For example, a 1.5 inch tall laptop is 3.8 centimeters (1.5 x 2.54 = 3.81).
Summary: Close the laptop screen. Start your tape measure at the bottom of one of the sides. Measure up to the top of the closed screen. Convert inches to centimeters (if necessary).
