Very long timescale stress relief in glass
If someone scratches a glass, it is becoming weaker at this point, and more prone to cracking.
But with time (tens and hundreds of years ) glass looses its shape because glass has amorphous structure. ...

Explaining refraction of light through a glass slab
Let's consider a glass slab ABCD.
Now a light ray is incident on the near end of the air-glass interface AB and is emerging from the glass-air interface BD. In such a manner:
Is there something wrong ...
