why do commercial ads usually offer products at $19.99 and offer a second product with it for free?
In my area, commercial ads about products always have the products at $19.99. I have never seen it higher. Also in the commercial they also offer you the same product for free if you buy it! Like buy 1 get 1. Plus, the commercial is on the air for a few weeks and you never hear of the product again.

what's the difference between a real image and a virtual image? and why does it matter?
This is something that I just could not understand at school, no matter how many people tried to explain it to me or how they explained it. It didn't exactly seem "too difficult" to understand, it just didn't seem to be logically coherent, i.e. it didn't make sense. 25 years later, can anyone put an end to my mental to...

mercury passing in front of the sun
So, today Mercury is passing in between the sun and the earth. However, a year on Mercury is 88 earth days. Does that not mean that this event should happen 4 times an Earth year?

the difference between software engineer(ing) and software developer(ment), if there is one.
Just wondering what the difference is, if there is one. It seems that people that I know in software engineering tend to have slightly different roles than other friends who are software developers. I can't put my finger on the difference though, so I thought I'd ask. Many thanks!
