Science & Mathematics - 30 July 2007

Hey I live on the edge of a city and the light pollution around my area is not severe,but it's not really contributing to my astronomy either lol.But I was looking out of my window and I have actually seen two constellations!,the constellation Ursa Major and Bootes!,I made out Ursa Major by starting with the tail and working my way down the line of stars with the help of identifying each with Stellarium, it's pretty awesome and shocking in a way that each star is 55,0000 light years away in space!,then I had a treat in finding another constallation, yep I navigated south +30 degrees using my skill of Azimuthal Grid and found the Constallation of Bootes, and at the bottom Arcturus! however my question is involved in the constellation Ursa Major, -0(just above) there are two nebulas called Bode's Nebulae and M101,has any of you Astronomers seen these Nebulaes through your telescope?

Take prime numbers: 2,3,5,7,11,13,... and write the difference between any consecutive numbers: 1,2,2,4,2,...; then do the same with this new sequence: 1,0,2,2,...; and over and over...
Can you prove that the first number is always 1 (except the original sequence of primes of course)?

I have heard this term for many years. I have tried to find out the exact origin of this, but to no avail. I have seen it explained in reference to a flakiness found around a portion of the human male genitalia (which is discredited) and also in reference to a tree root fungus found in certain climates in Mongolia. Does anyone know the true (and serious-no jokes) answer to this?

If someone could dig a hole through the earth and dropped something in how would gravity affect it.

If God perfected all species of life on earth,(in the modern era), thru His advanced knowledge of cloning, genetic engineering, trans genetics and other means of creating and altering life that we,(humans), haven't discovered or perfected yet,(what we call evolution),doesn't that mean what ever genetic changes our scientists are making to any of these perfected creatures are actually recreating less advanced forms of these creatures that God allowed to become extinct,(thru evolution), because they weren't compatable to live together with us moden humans He was about to make as His last genetically perfected creation? Are we creating freaks of nature like those on the movie The Island of Dr. Moreau? We can only prey to God that He is not going to let this happen!

I was just wondering...since they do deal with electrons, are they thought any physics concepts or even formulae in "electrician school" or whatever they are called?
And I know there is a big difference between an electrician and an electrical engineer, but can someone sum up the differences so I can have a clearer idea?

Solve the problem.
Two angles are said to be complementary if their sum is 90. If one angle measures (27) / (x) degrees, find the measure of its complement.

( 90 x - 27 ) / ( x)
( 90 x - 63) / (x)
27
63
