They de-energized the power lines that feed our home so that they could replace a transformer down the street . It looks like they put splices, or fuse like things, in the hot lines just before our drop line. They replaced the de-energized transformer, but didn't come back to do anything to "fix" what they had done to de-energize the lines in the first place. Why didn't they have to do anything to energize the lines, from where they "cut" the power ?

I hope this makes sense to you AC power folks.

In the US, we are taught that there are 7 continents (North America, South America, Europe, Africa, Asia, Antarctica, Australia). We are taught this 7 continent rule as if it were law. (At least, that's how I was taught.)

In some parts of the world, they are taught that there are 5 or 6 continents (I believe they are taught as America, Europe, Asia, Africa, Oceania, and sometimes Antarctica).

What are your thoughts on this? What makes a continent a continent? How were you taught continents? Any informed geography majors out there want to weigh in on this?

I have my own thoughts on how they should be taught, as a Political Science grad student, but is there a general standard based on physical geography?

If this plain is extremely wide and big, then gravitational field lines will be parallel to each other (like the case with electromagnetic lines for parallel plains). In that case gravitational acceleration will be constant, independently of the distance to the plain. In that case, if some object is placed far from the plain and starts to accelerate, its acceleration will be constant and independent of mass and time. Why can't this object exceed the speed of light then?

Anything is:
1. a part and a whole,
2. an equivalence and a uniqueness,

Nothing can be defined without these ideas.

Could you list the things that can be defined, anayzed or understood without these ideas?

Okay space is the stuff without matter - matter is the end of space. So now we discover that the atom is more than 99% space. It's now a ratio game and some scientists tell us the ratio of space to matter in an atom is roughly the same as the ratio of planets to space in our solar syestem.So now instead of asking how big we also ask how small. The concept of space nw goes both ways.
Okay now for the question How many places can life exist and how many of them do you think we are in right now?

Please remember I am not well educated on this matter Keep it simple .............I am curious

Has this speed been measured in any way? Since mass increases towards infinity as speed is increased towards the speed of light, what happens to mass as speed is decreased towards zero?
