So you say you are interested in science?

Hi all stp students and teachers!

It's great to see that you have set up this blog -- let's make it a platform to share interesting ideas and things about science you've thot of or seen with each other...

for a start, let me post something interesting here from youtube... it's called a non-newtonian fluid (some of u have seen this already in the physics session)




An explanation in wikipedia here tells us that your moms have been making this non-newtonian fluid for years -- a simple cornstarch with water mixture gives such a fluid. The interesting thing is its shear-thickening property -- i.e. the viscosity increases with applied strain (or applied normal force).

I found it really entertaining, but it also set me thinking "hey, it's really science!" -- and found myself really not understanding fluids! You know how in school, we teach u that liquid molecules are in long chains, slide over each other, not bonded that tightly... but how does this non-newtonian fluid have such properties that we can deduce from its molecular nature, arrangement or whatever?

There's much to learn yet... :)

On a different note, hope you check out my blog and read it! Leave a comment or a tag k? Even if i dun teach u, u r welcome to leave a note in my blog...

Cheers!
Mr Koh Teck Seng

PS: can we add a tagboard? (cbox.ws or something?)

Also, can we change the name of this blog/forum? to something cooler... erm... like Cool Science Blog! or Science Rocks... or Physics is Phun... haha... :P or something serious but not as nerdy sounding... like Science, Thoughts & Principles or something... suggestions, comments please?!
