Scientific Calculator ZENO-5000 is a lightweight web application (<40kb), utilizing latest HTML5/CSS3 features and client-side jQuery/Java scripting. Application does not include any graphic files. It is portable, capable of running in online/offline modes
on PC/mobile devices
Calculators software are extremely powerful tools, complementing/replacing their hardware counterparts. Calculators implemented as the web “thin client” type of application require the “live” Internet connection. There are certain
pros and cons in such approach: “thin client” web applications are “zero-installable” and platform/OS independent, which make them portable, capable of running within any major web browser (it’s relevant to mention, that web browsers
are rapidly becoming de facto a “virtual OS”, kind of substitute for real OS in regards to the web applications and services). The need for open Internet connection is certainly a disadvantage in many cases, thus it would be highly desirable
Such web application could either run in online mode as usual, or it could be downloaded and cached on the client’s platform.
Project contains 4 files to be placed in the same virtual directory:
1. Main file: zeno.htm (file contain dynamic link to jQuery library online)
2. Style sheet (CSS) file: oscZeno.css
4. Reference file: oscZenoRef.js
Fully compatible with Mozilla/Webkit based Web Browsers, presumably with IE 9. Tested on iPod Touch (Safari) and Windows Phone 7 platforms.

About this project
as rich internet application (RIA) with extremely small digital footprint. It does not use any graphic files: all aesthetic enhancements, like color gradients, rounded corners, box shadows, etc. are achieved via new features available in HTML5/CSS 3, thus
dramatically simplifying the page layout design and ensuring fast application load. Project ZENO provides deep insight into web applications client-side coding technique. Though intended primarily for the didactic purpose, it could be well suited and customized
for many practical computational tasks.
