understanding light

[Hrusai]

lol woops xD hey ho, if it teaches 1 person 1 thing im happy

aye, i think understanding pH its necessary to go into a bit more detail, its all very well and good to know how something works, but understanding it will make it alot easier to work with and allow more flexibility in knowledge etc.

heh, im a massive geek dude and proud of it! read new scientist every week and lots of other stuff on the internet besides


thanks for clarifying those terms for me mate! never come across them before, though i've never researched water specifically in any depth before.

presumably then as tds is all dissolved solids this would be the main measurement to determine water hardness? giving rise to the so called soft and hard water you get in different areas of the country....actually that would make alot of sense as having more dissolved solids would make the water feel different and cause harder water to be more abrasive and therefore better for cleaning, and the by-product of having more minerals and such like making it simultaneously more healthy to drink then.

ok thinking out loud now lol
