Before I get to the main topic of this post, I'd like to mention something. shortly after my last post, my girlfriend and I celebrated out 1 year dating mark! I'm not going to take up a bunch of this blog post with with rambling on about how awesome she is, so go check out her blog here.

So yes, now for the main topic. In the spare time that I've had, I've been working on...an app! Specifically, I've been working on an equation reference app for the iOS platform. I thought to myself, "how can I use my years of physics experience to make an app?" and this is the idea I came up with! I know that I can provide a more comprehensive solution than the few other similar apps on the store, so why not?

After investigating a few of current apps available, I found the following: the majority of them cover the basics well, have a limited physics section, and include some completely useless material (did you know that x+0=x ?? ). Now granted, I understand that not everyone knows everything, but I feel that some concepts don't require an entry in an app like this. That's why I'm not going to include stuff like that in my app just to "pad the equation count".

For launch, I'm aiming to include material that would be useful for a senior high school / early university student. Currently, the following has already been implemented:

- Physics
- Newtonian Mechanics
- Electricity and Magnetism
- Optics
- Fluid Mechanics
- Thermal Physics
- Quantum (basics such as photo-electric effect)
- Math
- Tables of derivatives
- Trigonometric identities
- Electronics
- Capacitors
- Resistors
- Inductors
- Error Calculations

Heck, I'd someday like to have equations from much more advanced material included (equations for time-dependent perturbation theory anyone?). For now, some more fleshing out of the math section is important.

So although a lot of the current apps have a number of the equations that I already have, their organization of the material is very poor. I'm approaching the problem from the perspective of someone who would actually find this information useful, so I'm able to organize the equations in a more optimal way.

I should also note that I haven't seen others with the error calculation equations. That alone could probably be packaged into an app. I know that every time I have to write a lab report, I constantly forget these ones.

There's a bunch I want to add into the math section before launch (integrals, geometry, taylor series, etc) and some tables (eg coefficients of friction for common materials). If there is anything that you would like to see included in the launch version, or in a future version, please let me know in the comments below, via twitter, or by email.

TL;DR

Making equation reference app for iOS, send me stuff you want included.

Thanks!

Any chance to have equations within the realm of probability and statistics? Things like Combinations and Permutations are easy and basic. Things like Binomial distributions and Bernoulli trials would be pretty cool!

Some basic probability distributions would be an excellent edition! I'll be sure to include the basics for the initial release.
