Re: [physicsnorthyork] Physics App

Hi Larry,

Thanks for your comments. I'm a big fan of Wolfram Alpha and the shortcomings of it inspired me to create this app.
Wolfram Alpha is great, but it's too generic and the end user is expected to know a large amount of concepts.

If you look at the below equation to calculate the work done in an Adiabatic process, Wolfram Alpha solved the equations brilliantly, but it expected the end set to enter the equations manually.

You can argue that one can make another search asking the equation and copying the results as new search item. But it had few shortcomings too.

It simply didn't solve the equations.

I couldn't find much luck with natural language processing tools too.

Probably it might work for linear equations.

As you can see, the Wolfram Alpha provides too much of options making it complicated and difficult for the end users to use it for simple things like calculation of certain equations in Physics.

This is where Physics Tutor comes into picture. As you can see in the above screenshot, it provides a simple interface to enter the unknown values and provides the result with detailed description.

3D plotting of graph is great, but in most cases, it's a premium feature in Wolfram Alpha. In Physics Tutor, end user can plot 2D graphs and can specify the range of X-Axis and plot the corresponding co-ordinates on Y-Axis.

With respect to support of images in definitions, I agree with you completely and shall work on an Update that will add the support of it.
Currently, the app provides link to the respective Wikipedia page of the topics and should help the reader.


Of course, Wolfram Alpha excels in its domain, but the main motive of Physics Tutor is not to compete/replace Wolfram Alpha in any way. The primary objective of Physics Tutor is to ease the learning of Physics, especially for the students who are often intimidated by the amount of Mathematics involved in it.

Also, as others have pointed out, all the services offered by Wolfram Alpha are not free.
I'll be happy to give this app for free, but I'm an Indie Developer and need certain amount to keep the servers for this app up and running, so I'm charging the minimal amount of $0.99.

I also have a Free app. It's called High School Physics - Free. It can be downloaded at https://play.google.com/store/apps/details?id=com.asb.full.highschoolphysics I highly encourage you to try this free app and provide your valuable comments and suggestions on the same.

@All,


Regards,
Arjun S Bharadwaj
