Puppies and CDs

Jen says...

Hi Jim,

Why does my roommate's puppy want to poop in my room instead of his? How can I train her to poop in his room instead?

Also, how do CD players work?



Jen, the question as to why a dog poops in one part of the house and how to make it poop in another part of the house is a misguided question. Dogs should not poop in the house anytime, anywhere, without some extenuating circumstance. Throughout the country there are farms that accept animals that don't behave. There they can live outside and poop anywhere and anytime. They are usually owned by a very nice elderly couple whose greatest joy comes from rescuing these wayward animals. Those dogs who insist on pooping in the house should be brought to one of these farms where they can romp freely and act badly. Tell your roommate to take his dog to the farm. If the dog poops in your room more than once, it is perfectly acceptable for you to take the dog to the farm. Remember, we have pets to bring joy to our lives. If we stop receiving joy from having pets, they need to be passed on to someone who they can bring joy to.


As far as how a CD works, there are plenty of web sites that get into the technical explanations of how they work, but let me give you the simple version. A laser is used to engrave "ridges" into the shiny CD media. During playback, the laser in your CD reflects off the high spots but not the ridges. A photo eye will pick up those reflections and turn that information into electronic pulses which in turn are turned into the music that you hear through the earphones or speakers.
