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!
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. Continue reading
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.
I recently came a cross with a great introductory video about mathematical proofs titled How to Prove a Mathematical Theory. The video which was produced by TED explains what is a mathematical proof, discusses a very brief history, and illustrates with an example. I hope you enjoy it as much as I did.
After introducing Primo, a new math game, I would also like to introduce Robocompass app, one of the latest online apps for compass and straightedge construction. It was only released three weeks ago.
Robocompass is an application that allows users to type commands and then turn those commands into an animated compass and straightedge construction. What is good about this application is that it has a 3d environment which allows the user to view the construction in any perspective. Constructions in Robocompass can be saved in Google drive and can be embedded in websites. Watch the introduction video and see the embedded file below. Continue reading
