Topics I've Started

  1. Corollary to cylinder problem

    09 March 2008 - 04:17 AM

    Take a cork cylinder of unit radius and a height of 2 units. Mark a diameter NS. on the top surface. Mark a diameter WE on the bottom surface at rightangles to the marked diameter on the top surface. Placing a knife along the NS diameter pass the knife at an angle through the cork to exit at E (end of the diameter on the bottom surface. Repeat the action allowing the knife to exit at W. Each of the two sliced-off chips have the same form as the water in the cylinder problem. The volume of each is 4/3 cu.units and has the same relationship to the volume of the cork (0.2122..) as the water to the volume of the cylindrical vessel.

    The cute thing about the cork "stump" is that its different cross-sections are a circle, a square and a triangle, three shapes in one form, so to say. Reminds me of the Trinity.:hihi:

  2. Cylinder problem

    06 March 2008 - 04:08 AM

    A cylinder with water is tillted till the remaining water forms an apex at the rim of the cylinder and the water line at the bottom of the cylinder is flush with the diameter. Question: what is the relationshop of the remaining water to the total volume of the cylinder. I encountered this problem many years ago. As far as I can remember the solution is a constant so that the measurements of the cylinder do not play any role. Can anyone help me please?

  3. Zylinderproblem

    06 March 2008 - 03:51 AM

    Ein Zylinder mit Wasser wird solange gekippt bis das verbleibende Wasser eine Spitze am Rande des Zylinders bildet, während am Boden des Zylinders die Wasserlinie bündig mit dem Durchmesser ist. Frage: Wie ist das Verhältnis von der verbleibenden Wassermenge zum Gesamtvolumen des Zylinders. Diesem Problem bin ich vor vielen Jahren begegnet. So viel ich mich erinnern kann, ist die Lösung eine Konstante, deshalb spielen die Maße des Zylinders keine Rolle. Ich suche erneut diese Denksportaufgabe mit Lösung. Kann jemand bitte helfen?

  4. Hallo there

    I'm a Newby and still trying to get to terms with the hypography system.
    My pet theme is magic squares.
    My nick is written with 2 t's (not with 2 s's) by the way. I thought I'd mention it
    before somebody jumps the gun.

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

When we launched in May 2000, we wanted to create a site to share science-related content of all kinds on the web. As time passed, our site turned into a pure science forum with lots of cool people.

So we kept the name Hypography and the cool science forum community - and aim to be a friendly place for discussion of science topics of all kinds.
