i'm trying to decide whether to go for an md/PhD program but I cannot imagine working in a lab full of mice even for medical endeavors. i don't have a problem with potentially messy human things, just rodents.

The distance between neighbors of a set of equally spaced atoms in crystalline sodium is 3.72 angstroms. If x-rays with a l=1.579 angstroms are diffracted by this set of parallel planes, calculate the angle 2q at which first-order Bragg reflection is observed.

A friend of mine had radical 360 surgery (on her back and sides) and I was wondering, will sleeping longer help her heal faster? How many hrs of sleep/day is optimum? How many hrs of sleep is too many/not effective?

I really appreciate your help!

I was in touch for a few months with a very close friend (the love of my life) for quite a few months, during a very pressing time in my life. He gave me advice and messages and told me things I could not possibly know as affirmation. He also liked to turn the televisions off and on and once even played with the doorbell on my daughters doll house. He also came to me 3 days before he died to tell me that I can not go where he was going. His words not mine. of course in the dream I had interpreted it differently than I did 3 days later. Chills. He stopped coming around often after awhile.... less and less. Now I hear from him very infrequently. Has any one else had an experience like this?

Why is it that particles can defy logic, as in the Double-slit experiment? How can an electron go through two slots at once, and interfere with itself? And why, through the act of observing, does the result change? Are subatomic particles aware of their surroundings??

(a) Vector a =?
(b) Vector b= 25 N
(R) Resulting Vector= 30 N
Theta= 104degrees

i need to solve for vector 'a' and i put it into the equation

b² + R² - 2bR cos(theta)
or
25²N + 30²N - 2(25)(30) cos(104)

but when i put the answer back into the regular equation:
a² + b² - 2ab cos(theta)

it doesnt work out >.< please help! i do best answers!
