Excellent book for autodidacts
Book pros: +Very clear information just as I have read from other reviews.
+Many exercises to try
+Beautiful illustrations
+Excellent for autodidacts
Book Cons: - This is the standard edition, so it does not include "modern physics" chapters (ch 38-43), but you do not need it unless you are going into research or advanced physics courses

Great projector. Just keep it cooled with a fan and laptop cooler
I bought this projector because I was looking for something easy on my wallet and of equivalent quality to modern LED projectors.
The first thing I loved about this InFocus W240 DLP projector was the resolution of the image; a nice 720p approximate, maybe more. There are plenty of settings built-in to adjust the image to my needs. The colors are vivid. I like the fact that it has a power saving mode, so it turns off automatically at a desired time, and as a result prevents over-heating. I like the fact that it heats up, makes it useful for winters (it doubles as a heater and projector)
The only thing I do not like is the fact that it heats up within an hour. Heating itself I have read causes the lamp to burnout faster, so I must have a fan focus on the intake vent to help cooling of the internals as I use it. I also use a laptop cooler to help it cool from underneath, which is where the lamp is actually located. If your eyes are tired you will begin to see what is called a "rainbow effect" where the colors projected seem to separate as you move your eyes, but that usually only happens during the night. Make sure you have plenty of ventilation because a small closed room will heat up within two hours with this projector.
