Hi,

I have often browsed here. It's a good site. I may not post often. Sometimes I have questions about the universe. Sometimes, I just like to stretch my imagination a bit. I did my maths and science many years ago. I am learning them again as my children grow up. My 10 year old is very smart, she noticed that when a=bd2 and a,b and d are all integers then √a x √b is an integer. eg. √7 x √28 = 14. It got me scratching my head for a while, but I think I'm fine with it now! It is about my level :wink:. I'm not a scientist or a mathematician but I may ask you some questions sometime, if that is ok.

Thanks

Ayjay
