A Reuleaux triangle is built from three circles. As it rolls, its height is always the radius of one of the circles - a constant. This makes it a curve of constant width, just like a circle. [more] [code]
There are many optional features included in this theme. And when I say optional, it means that you can choose to make them appear or not from the appearence section. All you have to do is enable/disable them. SO please read this post carefully.
Sidebar picture width:200px. You have the option to give it a circle shape,it will automatically be resized to 150x150px.
3 navigation icons (home, ask and archive) also optional. If you choose to disable them, the two columns on the left including the icons will disappear and those links (and the pagination) will appear as text under the description.
6 optional links under the “+ MORE”.
Pop-up askbox (optional).
You can show/hide the blog title.
Like and reblog buttons on posts (optional).
The right sidebar pictures will be resized automatically to 120x120px. This sidebar is also optional.
I also included in this theme the possibility to change the description font and font-size and the posts font and size from the appearence section. You’ll also be able to change the quote font size and include a Google Web Font name.
As usual, colorized scrollbar and selection.
All colors are customizable.
You can edit it as much as you want but please don’t claim as your own, don’t use as base and don’t remove my credit.
Please like if you use/like the theme. Thank you and Enjoy!
How to use the pop-up askbox:
The theme has a pop-up askbox (try it on the preview). It is optional, so if you don’t feel comfortable with it, all you have to do is disable it on the appearence section.
If you want to use the pop-up askbox, you’ll need to enter your url so that it works properly. To do so, go to customize, scrolll down and you’ll see this: “ASKBOX URL”. You’ll have to enter your url without http:// so it will look like this: username.tumblr.com.
Then you have the option to customize the pop-up askbox title, as seen in the preview. Again, you just have to type it on the appearence section, you’ll see “Askbox Title”, here it is.
Since this theme offers a lot of possibilities, I decided to make different static previews to give you some ideas of what you can do.
The circumference of a circle of radius r is given by the formula 2πr, where π is the famous constant whose value is approximately 3.14159265. This graphic by Margaret Nelson illustrates a simple way in which the formula for the circumference can be used to obtain the formula for the area of a circle, πr^2.
The idea is to cut the circle into a large, even number of equal sectors, as if you were slicing up a pizza. These sectors can then be rearranged into an approximately rectangular area. The upper edge of this area is made out of pieces of exactly half of the circumference, and the same is true for the lower edge. Half the circumference is πr, and the width of the area is approximately equal to the radius of the circle, which is r. The area of the roughly rectangular area is the same as the area inside the original circle. This area can be approximated by a rectangle of dimensions πr by r, which would have an area of πr^2. In the limit as the number of sectors tends to infinity, this approximation will converge to the exact value of the area.
Nowadays, formulas like this for area and volume are proved using calculus, but this elegant argument is a much older idea and goes back as far as Archimedes. It is not so important that the circle be cut into an even number of sectors, because an odd number of sectors will still give a good approximation if there are enough sectors.
The picture comes from an article in the February 2014 edition of the Mathematical Association of America’s magazine Math Horizons. The article is an interview by Patrick Honner of the mathematician Steven Strogatz. Strogatz is a professor at Cornell University who likes to cite this proof as a good argument with which to convince people of the beauty of mathematics.
A little sketch to look at sound waves from a moving source and the Doppler effect. I’d love to extend this and have a movable ‘Listener’ and emit frequencies based on the wavelengths the listener experiences.

↬sidebar image can be defaulted aspect ratio, circle, or hidden
↬long sidebar approximately 300px x 1600px
as long as you’re around that size its fine, the width could be bigger or smaller it really doesnt matter it will auto resize but if the image is a lot smaller than intended, the image is blurry and if the image is a lot larger then some gets cut off
↬posts can be with colour, with translucent colour, or without colour
