Chemistry (the etymology of the word has been much disputed)[1] is the science of matter and the changes it undergoes. The science of matter is also addressed by physics‚ but while physics takes a more general and fundamental approach‚ chemistry is more specialized‚ being concerned with the composition‚ behavior (or reaction)‚ structure‚ and properties of matter‚ as well as the changes it undergoes during chemical reactions.[2] It is a physical science which studies various substances‚ atoms‚ molecules

Role Models influence our lives Colby Burns Do role models influence our lives? Every person in this world will have someone in their life that they look up to‚ these people are considered as “role models.” Role models influence our lives by inspiring us to set certain goals and motivating us to achieve them.

In fact‚ I didn’t see another computer until

Key Questions Lesson 1 1. One argument against continuing research on the atom is that the cost continues to increase at an alarming rate‚ and the benefits seem to be declining. Whereas quantum chemistry experiments as early as 80 years ago were very cheap and yielded considerable practical results‚ now very few if any practical results are emerging‚ but the costs of experiments continues to increase. On the other hand a common argument for the continued

How technology has changed our lives Throughout the years technology is in constantly changing. It’s almost impossible just to think how different the technology was. I noticed how rapidly the technology change in our classrooms. For example‚ a video recorder or a side projector is almost obsolete now in days. We can now rely on most efficient technology. There are some good sides to this‚ for example we are no longer held captive by the prime-time schedules of a handful of networks. Now‚ with cable
