How to Create Soap Bubbles Polyhedra

Art and Math, Beauty of Math, Math Lite

Mathematical beauty is most of the time enjoyed and appreciated by those who have knowledge mathematics. It can only be appreciated by the common person in tangible things or perhaps things that can be seen by the naked eye. Symmetry, tessellations, and patterns are several of the mathematical beauty who can be shared by math and non-math persons. Well, let’s add one more: bubbles.

The video above shows how to create soap bubbles polyhedra and other 3d shapes. Some of the polyhedra shown in the video above are tetrahedron, hexahedron, octahedron as well as some truncations. It also shows some strange behavior of bubbles when they are suspended in the air.

Enjoy watching and share the fun!

Understanding Hilbert’s Grand Hotel Paradox

Calculus and Analysis, College Mathematics, High School Mathematics

Long ago, in a land far away, there was a grand hotel where there were infinitely many rooms. This hotel was attended by a brilliant manager.

One night, a guest arrived, but  the hotel was full — each room was occupied by one guest. The newly arrived guest asked if a spare room was available. “Of course we have, we are the Infinite Grand Hotel. There is always a room for everyone,” the manager said proudly.

Now since each room was occupied by a guest, the manager requested the guest in Room 1 to move to Room 2, the guest in Room 2 to move to Room 3, the guest in Room 3 to move to Room 4, and so on. Basically, he told every guest in Room n to move to Room n + 1. Since the hotel had infinitely many rooms, there was no problem in moving, there was always a room to move to. This left Room 1 vacant, and therefore, the guest was accommodated. The guest was happy. The manager was happy.  » Read more

Notable Posts in Elementary School Mathematics

Elementary School Mathematics

Mathematics and Multimedia has grown extensively since I first created in 2009, and honestly, I have stopped updated the pages or have created categories. There are many interesting posts that have been buried in this blog. Therefore, I will slowly post these categories in the days to come.

As part of this long term goal, I am now creating a list of topics under one category and create them as posts. This way, it will be easier for you to navigate them later. This is the first among these category posts.

In this post, I am going to share to you my notable posts in Elementary School Mathematics.

Area Derivation Series

I hope you enjoy these posts.
