Welcome Back To School- 1st blog assignment

I am very excited to be your science teacher and share with you my joy for scientific inquiry and thinking. There is so much we can learn from the field of science and yet so much to be discovered. Let the journey begin.

Your first blog assignment is to read about and explain any one unit of measurement from the dictionary of measurement and explain it in your post.  Some are quite complicated others are quite simple just choose any one of your liking  and tell us about it.   Maybe you want to choose something you have always heard about but never really knew what it meant.  Ex:  What is a terabyte?  See Below.


You will be graded on grammar and that you properly put your name on your post (follow directions tab at the top of blog - how to post.)

tera- (T-)

a metric prefix meaning 10¹², or one trillion. The prefix was derived from the Greek word for monster, teras. (Our words "terrible" and "terrific" have this same root.) The three prefixes mega-, giga-, and tera- thus mean something like "huge," "gigantic," and "monstrous," respectively. But also, and apparently by coincidence, the prefix tera- suggests the Greek tetra, meaning 4. This is significant because tera- is the fourth prefix, following kilo-, mega-, and giga-, in the list of SI prefixes for multiples of 1000ⁿ. This coincidence was exploited in defining the subsequent prefixes peta-, exa-, zetta-, and yotta-, corresponding to the powers n = 5 through 8 in 1000ⁿ, so that they suggest the Greek numbers penta, hexa, hepta, and okta for 5, 6, 7, and 8, respectively.

byte (B)

a unit of information used in computer engineering. Technically the byte is a unit of addressable memory, and its size can vary depending on the machine or the computing language. However, in most contexts the byte is equal to 8 bits (or 1 octet). This means that a byte has 2⁸ = 256 possible states. The unit was named by IBM engineer Werner Buchholz in 1956, and the 8-bit size was popularized starting in 1964 by IBM's System 360, a top-selling mainframe computer. The spelling "byte" is used instead of "bite" in order to avoid confusion with the bit.
