Math and Multimedia

Math and Multimedia is a great site for your mathematical curiosities and graphical pretties!  You can easily lose yourself learning from post to post.  I know I did.

For example, A Fascinating Introductory Video to Mathematical Proofs.  It contains a short, entertaining TED video about math proofs and why we need them.

(Honestly, I was looking for a reason to share this video but still provide the reference).

Enjoy the Mathy Goodness!

Happy Mother’s Day!

Ready to save some money on batteries?

1.5 AAA batteryLet’s say:

You have a TV remote or a small book light that uses three AAA batteries.  The TV remote no longer sends signals to the receiver and the book light does not turn on.  What do you do with the batteries?  Do you roll them around?  Do you rearrange the position of the batteries until the device works?  What if neither of those methods work?

An Imaginary Tale: De Moivre’s Formula in a Gif

I’ve been reading the book, An Imaginary Tale: The Story of i [the square root of minus one] by Paul J. Nahin and it’s really interesting!  I’m almost to chapter 4 and so far it’s been introducing some nifty ideas about complex numbers.  Among the content, we find a very convenient way of calculating the value of a complex number when multiplied by itself an integer amount of times.  That is, z^n=(a+bi)^n=r^n \cdot \left[ \cos\left(n\theta\right)+i\sin(n\theta)\right]\mid n\in \mathbb{Z}^+.  This is De Moivre’s Formula.

As a medically induced diabetic who drinks coffee, I can say this. LOL

Creativity Meets Math

Ever wonder if there’s any creativity in logic and math?  Do left-brained people struggle to be creative?  Where does creativity and logic come from?

Try out my Circular Design Maker.
* This seems to work better with the Mozilla Firefox browser

I was curious what it would look like if rotated rotating points around center points around another center point.  LOL. Try saying that 5 times fast!

Using GeoGebra, I made this worksheet for us to see.

Try making some designs and take pictures of them!

Creativity and Logic come from Curiosity.

Hate Math Love My Glasses by roxagrama

I happened to find this on Deviantart.com. This piece comes from roxagrama on Deviantart.   Although it has an ironic name, I think it shows a nifty perspective through the eyes of a mathematician.  Love it!  I’m curious what the formulas are describing?

Why Do We Need Math?

I know this is probably more of a reblog but I felt it was really important to show math students and teachers. Carl Sagan makes great points about who will be calling the shots in your life and in the real world when it comes to Science and Technology and this clip is less than 3 minutes long.

How to Calculate the Value of e

ever wonder how the calculator seems to know the numeric value of e ?  How could it possibly know?  e is an Irrational Number which means its decimals don’t repeat! (Specifically e is a Transcendental Number but it falls under the category of an irrational number).  So how can you fit an infinitely large number in a small box?  Or for that matter, how did Leonhard Euler manage to calculate e to 23 decimal places without a calculator?
