I recently saw for sale (from China) cordless anti-static wrist straps.  Apparently you just slip the bracelet on - no grounding required - and any static charge you might have disappears.  How on earth do they work?

Hypothetically, if a child was brought up without any reference to our human measurements of time (seconds, minutes, hours, days etc.), would it affect his/her concept of time passing?

For instance, we all have a general idea of how long 30 minutes is, but if someone was brought up without the ability to estimate how many minutes have passed, would they percieve time differently to the rest of us?

How can a body so far away from earth be so influential?

What is really meant by 'the moon controls the tides'?

We have been fascinated by the heroics of the Invisible Man.Off and on we keep hearing about the breakthroughs in the field of developing some kind of magic substance that will confer upon us the power of becoming invisible. But as soon as we apply basic physics there is a problem. Retina needs to be opaque to let the image be formed on it before the optic nerve takes the neural signals to the visual cortex.... which simply means that a completely invisible man will be Blind!! Isn't IT SO??

What makes a substance sticky?  Is it a macro property or a property of the molecules?

These are the photographs of a strange bug I came across during my stay in Manipur state of North East India. The dorsal view of the insect resembles a human face.  This semblance to human face doesn't appear to be by chance. What evolutionary advantage could have favored such an adaptation.

The convex side of the moon cresent indicates the lighted aspect facing the Sun, which means it points to the direction where the Sun is.

Can we then presume that the Convex side points to the West in night and the East in Early Mornings before sunrise. (Provided the moon is in Crescent phase of course!!)

Being a student of physics, reversal of magnetic poles of Earth has been quite a topic of concerned for me. But I didn't know that it's now shifting so fast.

The thing which I wanna know is, would this, shifting of magnetic poles of Earth, result in sun rising and setting from the opposite directions, I mean, after that Sun will rise from West and will set in East. I'm not very sure but what I've studied so far from that I think YES it would. Can anyone explain this?
