ScienceIsFunForum.com is available, but I wouldn't want to get in the way of the ScienceIsFun.com owner

ScienceSite.com ... they want $5,000 for it.

Scienceiscool.com is already taken, but some variation may work:
* ScienceIsGreat.com

NeedScience.com is available

#381 Re: Maths Is Fun - Suggestions and Comments » Science Website Names » 2012-12-08 12:22:11

Still negotiating on sciencehq.com

Sane Science    sanescience.com is available
Science Style    sciencestyle.com is available

ScienceIsFun.com is owned by Linda Froschauer, who is a leading light in the National Science Teachers Association. She intends to develop the site when she retires.

Excellent.

e^(sin(x)) is quite nice to scroll back and forth on

#386 Re: Maths Is Fun - Suggestions and Comments » Science Website Names » 2012-12-05 09:16:21

sciencelibrary.com is for sale I see, well done.

I need to add some new rules: no "_", and no numbers either.

#387 Re: Maths Is Fun - Suggestions and Comments » Derivative Plotter » 2012-12-04 22:20:34

New version 0.6, only minor changes, hopefully fixed the zoom bug that Bob found. (Use refresh!)

#388 Re: Maths Is Fun - Suggestions and Comments » Science Website Names » 2012-12-04 22:18:48

That is a cool story about 1564, Bob! 

And your and neolevans suggestion to brainstorm names sounds really good.

Must have the word "science" in it. Go.

#389 Re: Maths Is Fun - Suggestions and Comments » Science Website Names » 2012-12-04 18:00:26

These answers are "to the best of my knowledge" and I am no expert:

Is it less expensive for a name that hasn't been thought up yet?     => Yes indeed, like $10 to register a new name vs $1,000s that people want for names they already have.
Is it less expensive for a shorter name?      => not for new names, but people want heaps more for shorter names.
Are some dot-whatevers (vs .com .edu .org etc.) less expensive?          =>  .com is the most sought after,  .net is the "I couldn't get the name in .com" website
Are they not more flexible now in assigning the dot-whatevers?  Could something like fun.science be registered?       things like .science would be VERY expensive and needs to be specially applied for with reasons etc.

I wish there were a pricing formula! People buy up names and then just sit on them waiting for offers. Sometimes there is a fixed price, sometimes an auction, other times it is negotiation.

#391 Re: Maths Is Fun - Suggestions and Comments » Science Website Names » 2012-12-03 22:24:09

Another (similar priced) possibility:

Learn Science      learnscience.com

#392 Re: Maths Is Fun - Suggestions and Comments » Science Website Names » 2012-12-03 22:19:07

Nah, most expensive ...

(My luck in a nutshell)

But seriously, thanks smile

I want to start working on a Science website, the first step is to find a name. Most names are taken (such as ScienceIsFun), but I have these options so far (at differing prices):

Science HQ           sciencehq.com
Science Partner     sciencepartner.com
Unlock Science      unlockcience.com

Which do you prefer?

Good point about making an absurd example ... a useful tool.

#395 Re: Maths Is Fun - Suggestions and Comments » Bags of Marbles Flaw » 2012-11-27 15:27:15

Just for fun I ran some random trials in a spreadsheet, 1000 at a time, and got: 0.69, 0.67, 0.66, 0.67, 0.69, 0.69, 0.66

#396 Re: Maths Is Fun - Suggestions and Comments » Derivative Rules » 2012-11-21 08:16:49

I like f' because it is short and sweet. But dy/dx has the advantage of saying you are differentiating with respect to x.

Bob: thank you, those changes will make it better for sure!

Made a page on Derivative Rules

Lots of examples, possible errors (let me know!)

Also if you have any bright ideas on how to make it better.

#398 Re: Maths Is Fun - Suggestions and Comments » Derivative Plotter » 2012-11-19 21:45:09

Sounds like a glitch in the program ... will investigate, thanks.

I have made a Derivative Plotter

It plots the "derivative" by simply calculating successive points and working out the slope. I can't think of a simple phrase to say that ... "calculated slope"?

But a really cool feature is at the bottom where you get to plot a function in green to (hopefully) coincide with the "calculated slope".

Comments and Suggestions pretty please!

#400 Re: Maths Is Fun - Suggestions and Comments » Trying a new Introduction to Derivatives » 2012-11-17 23:18:56

Thanks guys.

I have also opted for f'(x) rather than dy/dx ... what are your thoughts on that?
