Atheists who love Science!

A group for science enthusiasts of all types -- professionals, amateurs, students, anybody who loves science.

Members: 1580
Latest Activity: on Sunday

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! :)

I'm familiar with mass and inertia, and a mass of people. 

Look up mass, weight, density, and volume under shipbuilding to see another definition.

Maybe this will help.

And now for the rubber myth (or should I say now for the truth about rubber):

I just found a better answer to the question: Does mass change when water freezes?

@Chris G I quickly found this definition and it jives with what I know and sorry to say, it does not jive with what you know.

Here's a more complete explanation of why water expands when it freezes. Wikipedia link

Comment by Chris G on December 11, 2011 at 10:51pm

Ice has less mass than water that's why it floats. Ice at the bottom of a glacier compresses from the ice above so has more mass that ice you would get out of your freezer. Think of a concrete hulled ship. Concrete has more mass than water, but because of the shape the mass per volume is less than water allowing it to float. 

Mass is weight-volume-density. Sorry, I haven't found a good web site to explain it yet.

I never though of it before, but rubber must expand as water does when it gets colder giving it less mass. As rubber gets hot - to the melting point is gets less porous.

Comment by Lary9 on December 11, 2011 at 9:17am

That has always fascinated me...the anomalous reaction of water and rubber. They both behave contrary to the laws of physical science and expand when cooled below 0 centigrade degrees. Does anyone know why? Is it something about the nature of crystals? Then why rubber? BTW. This exception is one reason why I became "hooked" on science at a young age...that and Euler's Constant for the sq root of negative numbers. I love counterintuitive stuff.

I found Miles Power by accident. He is on YouTube doing experiments. He is serious about science, but has a lot of fun with science. Check out this typical video:

One cup of water that freezes to ice has the same mass that it had when it was liquid. You can say the one cup water is more dense than the resulting ice because when the water freezes, its atoms are spread out in an orderly crystal formation which make it less dense than the water. That's why ice floats in water. In the special case of a glacier, the lower layers are less dense the higher you go. The ice at the top of a glacier is more or less the same as the ice in your glass of water. But the combination of being very heavy and solid and mobile, the glacier can erode the land much faster than wind and rain.
