## General Statements

I hate (cr)Apple.
I love onions.
I do not like using coordinates.

## Coordinates

You can find me in room 430, if you really want to.
If you find me on my rocking chair maybe I'm sleeping, I should however be alive.
I have strange working habit, I prefer to work in the late evening or night. So it's very unlikely to find me in the early morning.

## Book Suggestion

### GR

• Straumann is my favourite book;
• Misner, Thorne and Wheeler is an outstanding book that make you feel the weight of the subject. If you are patient it is your book;
• De Felice and Clarke is a nice book discussing the problem of measurement in GR;
• Wald: if you get over the shock of its typesetting is a very deep book;
• Weinberg's book, even thought a bit old, is by Weinberg, after all;
• Siegel claims that his book can be used also as a reference for GR. If you agree with him let me know;
• Landau's Classical Field Theory is for the allergic to math;

### Against "negative energy solutions" and "Dirac sea"

I consider using these expressions a crime against humanity because mankind is, by its own nature, curious and the product of curiosity are well-posed question and, sometimes, answers. Dirac was a genius and he predicted the existence of antiparticle. Nowadays we perfectly know that the energy of a(n anti)particle is positive, and that the void contains no (anti)particle. So why to use name reminding an incorrect and outdated interpretations? If your answer is "for historical reason", I invite you to refer to the muon as "meson" and to the calculus as "method of fluxions".

### Against the belief of certain mathematicians that the only Math important for Physics is ODE and PDE

Perhaps two or three centuries ago (even if, even at that time, it wasn't completely true)! Look at some papers by Witten, which is a Field medallist. How many differential equations did he solve?

## Efficient LaTeX Typing

Here I will collect some advices that made my LaTeX typing faster and more efficient. The basic idea is:
• If I can type UTF8 symbols like α ∂ and ∫ instead of \alpha \partial and \int directly in my .tex file I'll save a lot of keypress;
• moreover the source file will be more human readable.
So the solution seems to be to type UTF8 symblos directly in source file. Let's explain how this goal can be achieved:

### Modify Keyboard Layout

This can be done in different way depending on your desktop envinronment. However the following way ought to be DE-indipendent, for sure it will work on SISSA PC (with US keyboard).
