Will this way work?:
|x-y| < (2-x^s)/2
Substitute sqrt (2) for x, and you get
sqrt (2) - y < 0
- y < - sqrt (2)
y > sqrt (2)
y^2 > 2
sqrt (2) - y > 0
- y > - sqrt (2)
y < sqrt (2)
y^2 < 2
So therefore, y^2 does not equal 2, and you get your...
My 9th grade math teacher failed me on a square roots test because instead of saying "No solutions" for the square root of a negative number, I wrote "Imaginary". It's horrible how teachers can't just tell the class "Imaginary means no rational solutions".
Try adding Alligator clips to both ends of the split wire, and attach a paper clip to the ends of the Alligator clips, which are opposite the wire (Assuming a 2-way alligator clip). Then, put the paper clips in the water, and make sure the wire does not touch the water.
Also, try increasing...
Perhaps because if one goes back in time, before the time machine has been invented, they could end up causing a chain of events that causes the machine to not be invented. If the machine was never invented, the time-traveler never moved back in time, and you get a paradox.
It's a lot like the...
I would recommend that you take probably 30 minute breaks and do whatever you want, so that you don't get burnt out. If you do get burnt out, those next few hours are going to be worthless, since your body is going to be too tired to focus on studies and you'll find yourself most likely going to...

Ooohhh... An Ion Engine.... So, are there any stats out there on the engine? Such as, what fuel it uses, specific impulse and such?
And yes, I'm back after not posting for a long, long, long, long time... :biggrin:
More galaxies in the observable universe. Why?
As time progresses, we will be able to see more light from the furthest galaxies, numbering in the billions, and steadily increasing, compared to the number of stars in the Milky Way, which are decreasing.
That is the site of russwalters, who is one of the PF mentors who works on the Astronomy section of these forums. I think he has some tutorials about binocs somewhere on his page.
I'm not exactly a PF Mentor, but I do unofficially, and to the best knowledge of russ, do somewhat work with him on questions like these:
Yup... Math, and reasoning.
Imagine you are on a sphere, and you move in 2d. Eventually, you will move around the sphere, and come back to where you were...
