ann Posted March 12, 2010 Report Share Posted March 12, 2010 And I was hoping for something a little easier to understand . . . like fluid dynamics or something. Link to comment Share on other sites More sharing options...
Steph Posted March 12, 2010 Report Share Posted March 12, 2010 LOL. I got a B in fluid dynamics. That was a hard class. Link to comment Share on other sites More sharing options...
psia-antique Posted March 12, 2010 Report Share Posted March 12, 2010 Uh oh...now we're getting into calculus... ...I think... ...it's been a long time... We is a grammar error here.We aren't getting into calulus, they are. We who don't understand calculus are asking for the answers from those who do. I even heard that once upon a time, you could go out your way and find MBA programs without calulus. Link to comment Share on other sites More sharing options...
migbar Posted March 12, 2010 Report Share Posted March 12, 2010 This topic is more like geometry, I think. Calculus and trigonometry are stupid. Link to comment Share on other sites More sharing options...

roany poany Posted March 12, 2010 Author Report Share Posted March 12, 2010 Steph, thanks for splainin' that. There are three kinds of people here at Lou's marble Connection... those who are good at math, and those who arent. Link to comment Share on other sites More sharing options...
lstmmrbls Posted March 12, 2010 Report Share Posted March 12, 2010 Take a 1/2 inch marble and lay it beside another 1/2 inch marble now imagine how many more 1/2 marbles it would take to get that 1 inch into the shape of a sphere. That made it a little easier to imagine for me. Also I looked at how many marbles are packed into a glass globe I have and it is a whole lot more than I imagined would fit.

migbar Posted March 12, 2010 Report Share Posted March 12, 2010 m!b$.....What I meant by my dumb remark, was that calculus and trig rarely helped me out later in life, but algebra and geometry are useful quite often, and much more fun. Link to comment Share on other sites More sharing options...
I'llhavethat1 Posted March 12, 2010 Report Share Posted March 12, 2010 Yeah at first I thought we were talking about how many x" diameter marbles would fit into a y" diameter hollow sphere, where they are all only touching each other at one point. Calculating the volume might be easier by relating it to mass, so if a 1" marble weighs "X" and a 0.5" marble weighs "Y" than "Z" amount of 0.5" marbles are equivalent to an "X" marble. Assuming similar densities of course. I think Link to comment Share on other sites More sharing options...

ann Posted March 12, 2010 Report Share Posted March 12, 2010 Can we talk about plasma physics for awhile? I don't get this numbers stuff. "Steph, thanks for splainin' that.

marboman Posted March 12, 2010 Report Share Posted March 12, 2010 Just a guestion,do eight 1/2" marbles weigh the same as one 1" marble? or four 3/4" marbles? I can't find a proper scale. Link to comment Share on other sites More sharing options...
roany poany Posted March 12, 2010 Author Report Share Posted March 12, 2010 In my advanced astrophysics class at Harvard I did some further research.. I put water in a graduated cylinder and noted the level . I then placed a 1” marble in it, noted and marked the level again. I removed the 1” marble and added four 5/8” marbles. Sure nuff the water came even with the top mark. I then tried with various sizes of marbles . In conclusion, the calculations posted here matched my findings. (ok, I made up the part about Harvard, but it worked in the kitchen with a large shot glass and a sharpie) Link to comment Share on other sites More sharing options...

In conclusion, the calculations posted here matched my findings... Good method since there's "No replacement for displacement", when measuring volume as long as the densities are the same. Figure something like 1 Kg per L, or ~8.34 Lbs per USG for water or something like that if comparing by mass. Glass is pretty consistent but don't forget to account for the difference in mass if comparing a "hollow steelie" to a "solid steelie (ball bearing)... That could throw a wrench in the works. (Math can be dangerous. Handle with care) Laughing is healthy. lol Link to comment Share on other sites More sharing options...

That could throw a wrench in the works..... good point,I didnt consider that. so the glass need to make a run of nice bubbly 5/8" Peltier sunsets would be less than needed to make a run of say, NLRs.
