To convert from a numer base back into base 10 (that we all know and love)- take the number base that you are in, we'll use base 2, or binary for this example- for each place that you have a digit, take the number base, and raise it to the power of the digit you are at, and multiply that number times the actual value in that digit (sounds confusing, but is really simple, you'll see)- sum all the numbers, and you are finished!
For example:
Take the binary number 1101011. Here we have 7 digits or places. For each place, we have a value, broken down like this:
(Remember that "2" was our base, so all we did was raise to the power of the place location)-now look at the original number,
1101011. For each place we have a 1, we add the value of that place to the total. For each place we have a 0 we don't have to add anything:
1101011 = 64 + 32 + 0 + 8 + 0 + 2 + 1
1101011 = 107 (decimal)
Now a base 8 example:
467 (base 8) -> base 10?
Since
8^0 = 1
8^1 = 8
8^2 = 64
Then we have 4 of the third place, 6 of the second place, and 7 of the first place, or:
=(4 * 64) + (6 * 8) + (7 * 1)
=256 + 48 + 7
=311
So 467 (octal) = 311 (decimal)

Yes Ryan... perhaps my point I'm trying to make is between the lines. There are several "Ice bergs" in the field of
wanting to be an "...electrical engineer of some sorts" and having an interest "...in robotics and high power microscopes".
There are many many things to learn, but you can't let yourself get discouraged, I learn everyday. What you get out of
school are building blocks, what you decide to build is entirely up to you.
The thing is, electronics in school is very generalized, your question leans more specific but still very general. What is
it about robotics that you like? Are there specific areas of interest? Same goes for high power microscopes... Do you
want to look into space, or peer into the sub-micron world here on Earth? What makes you "jump" when you see
something you've never seen before in a microscope? ... Or putting 2 and 2 together in a way that makes you feel a
foot taller for a day? These are the types of things you should ask yourself.

Well, I saw a LEAP microscope in action and that was awesome. I really .like to the atomic structure of things my own eyes can't see, it is very cool. Robotics? If I went that route, I would probably want to make robots for deep space/mars. I would love to see the first man/woman set foot on Mars, but to be apart of that...wow. It all seems above me in a way, maybe it's normal, I just do my best to prepare just ya said. Does parallax use SEM, all of that is amazing too. Geeze, that's it really.
No matter what you go into, learn as much math as you can. If you are interested in learning more along the lines of my previous posts, let me know, I'd be happy to help you.

Don't worry about this, even very experienced people have vast realms in which thier knowledge is basic at best. This goes with the territory, no matter how much you learn, there are always things which lay just beyond your grasp at the moment. It is a truism that every answered question produces·ten more questions. What is important about education isn't what you learn, but learning how to learn, because you will be spending the rest of your life doing just that, learning what you don't already know. That is why math is so important, it is·a tool to understanding other things.
Is that guy (story of 1) King Aurther in Monty Python and the Holy Grail? Anyways, thanks. I went to the library, and found a HTML book, but it is from 1996, has it changed? If so, do you know of a site I can get the necessary software for it?
Yeah I would like to keep learning about the previous stuff. I will have to print it out and read it again, but it's pretty neat. Ok, here is a pretty simple question:
There is a baby bull on one side of these tracks, and a mama and pappa bull, train comes through and scares the baby bull, which parent does it run to first. Tell WHY (this was annoying to make by the way...)

This one is not a trick, it will make you think though.
A man is floating in a boat in a pool. There is also a large stone in the boat.
The man pushes the stone out of the boat and the stone sinks to the bottom of the pool.
Does the water level in the pool go up, down or stay the same (as when the stone was in the boat).
See if you can figure it out BEFORE you google it...

I know the answer, but I'll let others answer it. I first saw it on Mr. Wizard on Nickelodeon back in the early-mid 80's, though he posed it as: If you fill a glass with some ice cubes and water so that it is filled to the brim such that only the surface tension of the water prevents it from spilling (ie the height of the water is actually slightly above the level of the glass), the ice cubes protrude a fair amount above the surface of the water, when the ice melts will the glass overflow?

Bean - I say it depends on the size of the stone. The stone's displacement while in the boat is based on it's weight and the surface area of the boat. The heavier the stone the more water it displaces. When the stone is dropped overboard into the water; how much water it displaces is determined by the stone's volume. Therefore it depends on the density of the stone as to whether the water level goes up or down or stays the same.
I say no because the ice cube's volume is larger when frozen so if it melts the volume will actually decrease. water expands when hot or cold. The surface tention will not be greater.

For example:
Take the binary number 1101011. Here we have 7 digits or places. For each place, we have a value, broken down like this:
First digit: 2^0 = 1
Second digit: 2^1 = 2
3rd: 2^2 = 4
4th : 2^3 = 8
5th: 2^4 = 16
6th: 2^5 = 32
7th: 2^6 = 64
(Remember that "2" was our base, so all we did was raise to the power of the place location)-now look at the original number,

EBRN = (Sign * Mantissa) * (16 ^ Exponent)
Where:
S = Sign
E = Exponent
M = Mantissa
One Key to remember is that the Exponent is in excess-64 representation.

This is a standard used for GDSII files (Common·format used in many·IC layout·programs).
It basically is 64-bit double precision representation.
IEEE uses 11 bits for the exponent (excess 1023)·and 52 bits for the mantissa.
GDSII uses 7 bits for the exponent (excess 64) and 56 bits for the mantissa.

I think.
Doc
drop the rock then the water stays the same.
ice cubes are less dense than water, they float; hence the level drops.
