  • Guy locks eyes with me?

    So this guy I like, sometime we are a bit flirty with each other and stuff. We were saying bye at a dinner with friends and we side hugged and our eyes just locked for a while, both of us smiling. Does that for sure mean he likes me even though he may not be really ostentatious about it?

    I really don't understand why I am always single. Never been in a relationship and 21 years old. I'm smart, decently pretty and I know I'm a picky person. Reality is that I am hardly attracted to anyone and when I am I get really excited because I know theres nothing wrong with me. I don't have a lot of time to go out but when I do, I feel like there's not quality guys out there. People always say to wait and stop looking and it will happen. I feel like thats a huge web of lies. People are now starting to pressure me and question my sexuality because I am alone. Please offer suggestions.

  • Is it a good idea to ask a professor about reading other than what we are studying?

    My professor is a neuroscientist and I wanted to email him to ask him if he knows more about the music and brain connection and if he has any other reading on it. I have already been to his office hours once or twice to ask him about perfect pitch. Do professors get bothered by things like this or do they enjoy it?

I divided 106.42 by avogadro's to give me the mass of one atom which is 1.76 times ten to the negative 22nd. then I multiplied that by 4 since Pd has fcc structure, hence 4 atoms. Then I did v=m/d so 7.068 times 10 to the negative 22nd over 12.0 (it's given density) and I got the volume to be 5.89 times 10 to the negative 23rd. Then I cube rooted the volume to get 1.80 times 10 to the negative 4. The formula in my textbook says a= root 8 times R my A value is the 1.80 times 10 to the negative 4= root 8 times R I got my final answer to be 6.36 times ten to the negative 5th. Where did I go wrong? That's not the right answer. It should be .138 nm
