Re: [seul-edu] Phase 1 Science Evaluation

Hi folks,

My opinion: If you are learning how to convert units then 1) you should do it
manually so you know what you're doing,
I don't agree with Charlie, because the idea of computers is to help the
humans. IMHO if you are going to learn how to convert units, a unit
conversion tool will be very helpful.

         Not to me or any kids I know. Vote=NO.
Here I also don't agree with Charlie. I must admit, that I was very
disappointed to read that.

I'm the author of the NumericalChameleon and I get a lot of positive
feedback about this tool:

- hundreds of emails from school kids and parents how great the NC is,

so you can assume that the NC will be used all over the world (even
if it's not on the ISO ;-)
- mentioned at Sun's Swing Sightings:
http://java.sun.com/products/jfc/tsc/sightings/S13.html (at the bottom)
- mentioned in the c't (famous german IT newspaper)
- more than 7000 downloads at sourceforge.net
- more than 4700 downloads at chip.de (famous german IT newspaper)
- more than 3500 downloads at www.freeware.de
- more than 1900 downloads at www.freewarepage.de

The NC will help you to understand physical units, like length, volume,

time, electricity, magnetism, etc. (even if you are not at school
anymore). Currently 1600 units in 75 categories are supported. Also
roman numerals, bits&bytes and radixes can be converted.

It's not only a physics application; if you would like to learn a
foreign language, the NC will help you to learn reading and writing
numbers literally. The NC currently supports 15 languages (up to value
1e96). Examples:

12345678 [Decimal] = twelve million and three hundred and forty-five
thousand and six hundred and seventy-eight [English (US)]

12345678 [Decimal] = twelve million and three hundred and forty-five

12345678 [Decimal] = zw=C3=83=C2=B6lf Millionen

12345678 [Decimal] = doze milh=C3=83=C2=B5es trezentos e quarenta e ci=

The NC is absolutely free OpenSource (GPL) and due to Java it runs under
each Unix derivate (Debian, Mandrake, Suse, RedHat, MacOS X, even
Solaris are tested). For those how don't like UNIX, it runs also under
Windows.

Well, it's entirely up to you guys, if you found that a tool like the NC
is not worth to be on the Seul ISO.
