Whether you're a professional, a student, an amateur, an enthusiast, whatever! Lots of atheists love science. Might as well have a group for it!

Feel free to nerd out, link articles, talk about your favorite field of research, whatever!

I've been super busy with school this semester -- no time for Atheist Nexus, sadly!!
If anyone who's around here a lot wants me to toss them moderation privileges to run this group or anything, just send me (Sara) a message! Thanks!

Removed ability to send mass messages to everyone in the group. At 1000+ members, that seems like asking for spam.

Offer still open if anyone active in the group wants moderation privileges, but it appears everything has been going smoothly with all kinds of great discussions without moderation. Fantastic! :)

First off....it's not the AREA that's changing, it's the VOLUME.  I can't say that loudly enough.

 

Re. "Frost Heave"...typically a vertical movement is called "heave."  When it's caused by water freezing into ice and expanding....well, there's your frost.

 

@Joan: Are you freezing your too-full grape juice jars, or are they "just breaking" somehow?  A jar with a re-entrant top (one that "narrows back down") is at greater risk of breaking when the liquid inside it expands than, let's say, a glass that tapers outward from the botom to the top.

If water in a glass freezes and does not change, what changes?  

"In the example of the freezing of half a glass of water, the water does not lose or gain any mass. The Mass stays the same, but the Density and Area change. 

When I fill my grape juice jars too full, they break ... huge mess!What am I not getting here?

Driving up the Alcan highway I encountered many, huge frost-heaves; was it not the water that caused them?

Parts of Spokane are built on basalt and water flows through it like a sieve.  Our homes and buildings dance all over the place during change from summer to winter and back again. Part of my driveway lifts 3 inches every winter.  Is it water changing to ice? or something else that makes it have greater volume?

What I want to know is: if you take a half-full glass of water and put it in the freezer, is it still half full, or is it now half empty?

Thanks, Clarence; I was about to step in, myself......

Cool link. Thanx, Ruth.

mass/atom vs mass/ unit of volume .
Comment by AtheistTech on December 12, 2011 at 3:49am

Yes sir, Chris G, we are in agreement. I took a look at your profile and did not see math as one of your fortes. If you understood algebraic math better, I could give a better explanation why a 1/2 glass water has the same mass as the ice created from that 1/2 glass water, but surely has a different density. I am not an educator either, but I feel I have a good handle on Mass, Weight, and Density. Merry Hanukkah! Oops! Is it Happy Christmas? Or maybe Pleasant Kwanzaa? Oh shit on it! Happy Holidays! (including Happy New Year!)

We probably are in agreement.

Check this out.
