I'm sure you smarties know the answer. I didn't. It all came on the back of "Can you destroy a diamond easily?" question... And I learnt that you cannot dissolve them! No acid will apparently touch them. But yes .. they are hard to cut, however not strong and easily smashed with a hammer.
So what random questions have you found answers to recently? And did they made you go: oh, wow!  |

Strong is a generic term, and is very subjective. It isnt measurable where as hardness is. There are various technical ways to categorise strength.
Yes diamonds are hard. Their molecular composition is very unique, the molecular bonds are strong and hard to break, giving it it's 'strength'. |

Thank you ! That's some great learning today. |

And for the 2nd part. I didn't learnt his recently but it intrigued me.
Glass is technically a liquid and not a solid. Its a super cooled liquid. If you look at really old windows, like in churches, the glass is thicker at the bottom than it is at the top because gradually over time it lows towards the bottom. Very fascinating fact to me |

I did notice that ! Im a huge fan of an old window. Especially if it has a stained glass. 
I wish I paid more attention to science. Now I find these things fascinating I found myself lacking some knowledge too. Never too late to learn. |

Hat tip to DecadentDevon for this one from earlier today:
There is no species called 'seagull' - it's a generic name for any gull living mainly by the sea. The big evil buggers who want your chips are usually herring gulls. |

The strongest material known in proportion to its thickness is graphene.
Used to make carbon nanotubes which are only visible under a microscope but 100s of times stronger than steel.

Physics.
Google " nobody has Blue eyes". basically the same reason as the sky looks blue but isn't.
Although people with Brown eyes do have brown eyes |

It's an amorphous solid and the thicker at the bottom thing is a myth, that is down to manufacturing methods. |

So the older the glass the less reliable were techniques and the imperfections would have been due to that ? |

What are nanotubes used for?"
Batteries, car parts, electronics, coatings.
It's a small field at the minute but is growing rapidly |

Graphene was first isolated at the University of Manchester in 2004 by Professor Andre Geim and Professor Kostya Novoselov. They won the Nobel for their work. |

I've seen lots of newborns. And true that. |

I'm waiting for some fab Sheldon to pop in and explain;-) |
