Thank you Definition and 70 Threads

Is it really common practice to send a thank you email after a job interview? At all of my interviews I have concluded by thanking the interviewer for their time etc., but never sent a thank you email. To me, it seems redundant, pushy, and smarmy. Or is this common practice? What would you think...

I just stumbled upon a post I made when I was a kid here (16 then, I'm 33 now). Rudely, seems I never followed up and I can no longer reply in that thread. Wherever you are today @FredGarvin and @Artman, the hovercraft worked. In fact it worked better than expected and we immediately crashed it...

I am not sure whether this thread will get many responses, nor am I sure that any nurse will ever see it. Maybe @Greg Bernhardt can promote it on facebook. Anyway, I strongly feel the urgent need to acknowledge what they all do for us. I had the chance to closely observe the work nurses have to...

Thank you for your time and consideration.

Dear all, I officially passed all of my exams yesterday. It seemed very unlikely but now I get to study physics and hopefully pursue my childhood dreams. I want to really thank you. I quit my job and was on a budget so that I couldn't afford tutoring, but I don't think I would have been able to...

I think a ray is electromagnetic, is mass-less, and could be described as a photon. A ray must travel at the same speed as "c" in the same medium. I think the term particle is used in atomic studies as a physical piece of matter, one that has mass and could hold a charge or be neutral. Being...

Hey there! This is Mayank Bhandare, from India. I am a recent graduate in Mechanical Engineering from the University of Mumbai. Though it's a strange switch as many would say, I am planning to pursue a career as a Theoretical Physicist/Cosmologist. I have a couple of entrances the next month...

∫x^2(√(x^3 + 1)) u = x^3 + 1 du = 3x^2dx (1/3)du = x^2dx ∫√(u)*(1/3)du = 2/3(u)^3/2 *(1/3) = 2/9(x^3 + 1)^3/2 Is this the correct answer? Thank you.

Dear all, I am a lover in astrophyics, however, I have not got much knowledge in it. Recently, I read a book and it says " the mass (of an object) increases as its velocity goes up", I don't think my brain works for this sentence... I seem to remember that P=M*V, so literally, if velocity...
