Depression and Skewed Perception of Time

I have clinical depression and I have a skewed perception of time, which I hear is common in depressed people. I will wake up and want to do something productive, but instead if I can't find the energy or will power I will busy myself with unimportant things and watch the hours fly by. Hours turn to days, days to weeks, etc. One day I look up and it's March 8, 2013. On the flip side, on the days I do manage to do something productive time drags by at an agonizingly slow pace. Actually being productive exhausts me most days, and this dragging of time doesn't help at at all. I'm on an antidepressant and seeing a therapist, but I was hoping to find some way to better keep perspective of time? Instead of having all my days morph together. Also looking for ways to better cope with working since I work from home.

What does acceleration in deep space feel like?

Humans can supposedly sense acceleration. So what would piloting a spaceship in deep space feel like? General confusion about relativity inside. [more inside]

Special Relativity Question ;)

This one's for us physics nerds. - Is the speed of light our universe's only true constant? And does this explain why time dilation occurs most for extremely massive objects? - Does time dilation only occur when an observer is present?

A Problem of Scale: Halfway in size between an atom and the universe

"A human is halfway in size between an atom and the known universe"... This is a paraphrased quote I have come across several times. I like it. Who said it first? How true is it in the most literal sense? And, finally, what errors arrive in postulating a universe, or an atom, which can be measured AT ALL from our singular, relativistic, perspective? [more inside]

Time dilation and relative speed

Time dilation and relative speed. If the speed we travel is relative to the thing we're travelling away from, then how does the universe know which of the two things is actually moving? (so time dilation can occur) Is there a known universal "zero-speed"? If so, at what speed is the earth moving, and would it make a difference to the time dilation depending on the direction a spaceship moved away from the earth?

Explain Theory of Relativity

trying to get my head around special relativity filter: Can someone explain to me, in terms as devoid of mathematical formulae as possible, how something traveling less than the speed of light cannot be accelerated to the speed of light?

Quick, cheap poster of MC Escher's Relativity?

Ok, I want to get my friend a poster of MC Escher's Relativity. The catch is I need it by Sunday, and I can't afford to spend more than a tenner. Can anyone suggest anywhere either online or in London that I can get it?
