I have some data and in said data I had 2 peaks, to which I fitted 2 Lorentz functions. The sum of these 2 functions gives me a 3rd function. Now, I need to find the integrated area of the 3rd function. Originlab gives me the area of the 2 fits, but not of the 3rd function. Summing the area of...

Oh. It's sad that not everyone has access to that. Oh well.

@Greg Bernhardt, could you please explain something to me: What does "Live Alert Update" mean? It says that's a feature for gold members.

What kind of collaboration tools do you guys use in Physics? Let's say you need to work in a group for a class. How do you collaborate with the other members of the group? Do you use a special messaging app? Github? Trello?

I'm interested in finding the polarizability of NaCl. Let's say I have the polarizability of ##Na^+## and of ##Cl^-##. Can I sum these to get the polarizability of NaCl, that is: $$\alpha_{NaCl} = \alpha_{Na^+} + \alpha_{Cl^-}$$ Honestly, that does seem very accurate, but perhaps it's to a...

I remember browsing the general discussion and it had new and interesting posts/threads every day. Nowadays, it seems to be the same person creating new threads, perhaps in order to keep it alive? Even though my account is new, I've been with PF for some years. The change of forum-software was...

I don't think one should use mathematica as an alternative to pen/paper. It complements it. There are some stuff that you absolutely cannot do with pen/paper, for example, computational work. However, for managing some integrals and such, I'd say that pen/paper should be your 1st go-to.

So, I've heard from several people that Origin is used as a spreadsheet alternative in the scientific community. It seems to be a proprietary software (baah) and I couldn't find anything about a native linux solution so I ask: Do you use Origin in Linux? If so, how do you do it? Wine? VM?

I normally donate to wikipedia as well.. Not much though (5 or 10usd), since I'm a student and we're pretty poor, so the legend says.

Why not a news section for any physics related news?

wow, you really are giving that away? wow, that's nice of you. I initially expected a package from 1990 but that's not the case. Good on you.

So, according to several papers, after graphene's production via CVD, one wets the Copper-Graphene substract with DI water. I was wondering what's the point of doing that?

You would either need to encrypt the files before uploading or use a cloud service that has client-side encryption. I agree with that sentiment though. You've a 2TB SSD? Holly.. I didn't even know these existed yet.

Thank you for all the answers so far! You've been giving me some great ideas on how to do it myself.

Hey people, first post in these forums, though I've been lurking for quite a bit. I was wondering, how's your backup system? Do you use dropbox? Premium or free? Any alternatives? How do you do it?
