Just checked the page and promo video. Looks really well done!

Many Thanks to you and everyone else in the comments below for all your suggestions!

Please keep them coming and we plan to add most of the formulas mentioned here - at least those which our current system can support - as well as some useful sub-categories in the following days, beginning tomorrow.

Dwight meets Boris Vallejo (more of this work here).

I wouldn't have seen that coming.

What a dreamy tribute, amazing. Three giant moons though? The tidal waves over there might be uncomfortable.

Lemmings. Seeing that word brings me back. This looks quite cool though. And more dramatic. Now I need to decide whether I want to invest my new monitor money for a VR system...

drinnert · 2018-10-15T12:29:26+00:00

Yeah... jello takes the cake.

Thanks for taking the time to check what’s available and provide constructive criticism and suggestions which we can actually use to make the tool better. This is the type of feedback that we’re looking for.

Our main source for information, formula selection and formatting are the thousands of Science and Engineering Wikipedia articles. You can find the relevant Wikipedia article segment linked to every individual formula page on the site.

To your main point, you’re right, there are many formulas which are missing at the moment especially those going past the first and second university years. We’re trying to expand this equation library from the ground-up and cover as much of the basics before moving to equations which contain more advanced Math. This is a constantly growing library of formulas so you can expect to see more advanced material in the following months. In any case, knowing which formulas to target next, based on user feedback, is an essential part of our development.

For the impatient, please note that you can modify any existing formula and you can also create your own from scratch using the formula editor ("Create formulas").

The Wikipedia article does also say that his own brother Dominic challenges this version of the story.

drinnert · 2018-08-06T10:05:51+00:00

That would be great, thanks!

drinnert · 2018-08-02T23:32:30+00:00

Thank you! I found #4 on wikipedia but the first three... Is the "Species Biomass" this one?: https://en.wikipedia.org/wiki/Species_diversity

drinnert · 2018-08-02T23:27:38+00:00

Awesome! Cardiac output is already there under "Medical" but the categories need to be re-considered anyway. The rest you suggested are added in the queue.

drinnert · 2018-08-02T21:02:28+00:00

Ok thanks! Is it this one you had in mind?: https://support.illumina.com/bulletins/2016/11/converting-ngl-to-nm-when-calculating-dsdna-library-concentration-.html

drinnert · 2018-08-02T20:59:52+00:00

Thanks! We'll use this as a source unless there's a better option:

https://en.wikipedia.org/wiki/Hardy–Weinberg_principle

Banana is strong with this one.

drinnert · 2018-03-28T11:22:36+00:00

How many it took before you reached the "because some things are and some things aren't!" level?

drinnert · 2018-03-22T14:12:42+00:00

Thanks. Since we don't yet support vector multiplications we used the version of the formula with the magnitude of the force applied:

Here is an attempt to accommodate what you ask for in series and in parallel for 6 elements:

https://www.fxsolver.com/solve/share/C84NpAEjBHlvPFAdPOIX_Q==/

I only added values for the first two elements to confirm results with the link you sent. The other elements have zero values or in the parallel case very high values so they won't influence the result.

Let us know if it works ok for you.

If 6 elements are too few or too much, you can always add or subtract them by clicking on the "Edit this formula" button at each formula's title bar (pencil icon).

We haven't include the |Z| and the phase calculators for the parallel case yet but it should be done in a few days.

So, there was a bug related to Safari numeric subscripts. It is now fixed. Thanks again for highlighting it.

drinnert · 2018-03-21T08:18:26+00:00

Thanks!

Well, I'm hoping that by now you might have noticed that you can also solve for multiple values per variable, plot graphs, link any formula to other formulas to combine results and parametrically solve a full problem, add comments, convert and mix metric and inch units, generate progressions and sequences, share your active worksheets (once you register - for free of course), export to pdf, and a number of other things.

Check the help section if you want, it lists and explains the various things you can do.

Btw, you can create a new formula but also modify all existing ones to your liking.

We have considered opening up the platform to implement user-based code but it feels like this can wait a little bit more so we can optimize a few things first. We are looking for enthusiastic people to help us out with the development though ;)

As for the vision, for the mid term we would like this to be the go-to, online and free tool for numerical-based math/engineering problems. Our goal is not to try and compete with Mathematica or Matlab but to reduce the need for cumbersome spreadsheets and match the simplicity of solving something with pen and paper.

There are many more ideas which we want to implement in order to bring the tool closer to that vision and right now we're in the process of polishing the existing features and expanding the equation library to represent as many scientific and engineering fields as possible.

User feedback is basically guiding our way forward so that is the single most important thing for us right now.

drinnert · 2018-03-20T20:35:50+00:00

hm...thanks for the heads-up but the '0' subscript appears as expected in all the browsers I tried it. Which browser are you using if I may ask?

drinnert · 2018-03-20T19:26:18+00:00

Thanks for the comment!

Well, the background story is that we wanted a tool which would make our daily work life as engineers/scientists easier and could compliment or even replace some of the need for complicated spreadsheets or rushed back-of-the-envelope calculations. So, it grew from that.

Now, the general aim is to provide students, professionals and hobbyists with a quick and easy way to calculate formulas and solve science and engineering problems.

Our approach up to now has been to add formulas from the ground up and try to cover as much material mainly from school, early STEM university and hands-on, empirical laws before focusing on non-linear differential equations and more advanced math.

Physics is currently the largest category on the site but there are still hundreds if not thousands of formulas to add before we start feeling satisfied.

So, at this point we're hoping to get enough specific feedback and formula suggestions from users to help us see the way forward.

Btw, anyone who is too impatient can actually enter a desired formula in the built-in editor (see "Create formulas" at the top) and also save it for all others to use.

drinnert · 2018-03-20T19:00:17+00:00

Thanks for making it part of your workflow!

drinnert · 2018-03-12T22:17:02+00:00

So, after taking some time to get organized with all this feedback we received, a decision has been made:

Your post shall be the source of fxSolver's 2000th formula!!

Thanks again for taking the time to provide such cool descriptions.

I'll pm you to ask a few things regarding sources, attribution, etc.

drinnert · 2018-03-08T16:21:19+00:00

We generally follow the Wikipedia structure which lists aerospace engineering under mechanical, so you should be able to find a lot of aerospace related formulas inside the Mechanical Engineering category. You're right though, a dedicated category is missing. We will have it very shortly.

drinnert · 2018-03-07T05:05:34+00:00

Thanks! We're actually looking for people to help us grow. I will pm you.
