The main difference is that electrons are readily available while muons have to be created. I think there are some experiments with high energy muons, but for the proton radius, you want low energy. PSI creates them accelerating protons and

I don't think ROOT is very common in the atomic community. For experimental control, LabView is quite common, and it seems to have pitfalls too. But from what I know, the experiment itself is very straight forward, there are not so many pla

I second that. The aim of root is certainly good. But the implementation of that idea, especially the overall design, is absolutely awful. It's understandable, it has grown over a long time and was written by physics experts, not software

In my PhD, I measured the proton form factor and, from that, calculated the radius. So let me explain my view :) There are essentially three ways to measure the radius: 1) Electron-proton scattering. This gives you the form factors (related

The first problem is to produce low energy muons. There are only few facilities in the world which can do that. The second problem is getting the muons slow enough to bind with the protons, and making sure the muonic atoms are at the right

I guess the possible magazine sizes play a role here. I can't imagine a hunting rifle with a 100 round mag. And aren't most of them bolt action, that is, not even semi-automatic?

BMW started to include more configurable buttons. I think that is a good idea having the best of both worlds: Keys for the functions /you/ need most often, and not a ocean of keys for every possible thing. Too often usability is sacrificed

I feel they did improve with later versions. For example, they now have keys you can program with arbitrary functions.

But even a async database should be able to write something to its log after it discarded the write request. From what I understand from the original article, this did not happen.

Maybe stupid question, but isn't there mmap64 and mmap2 with which you can map larger files? You are limited to 2 gigs at a time, but that shouldn't be a complete show stopper.

Doesn't solve the problem how to find the gold nuggets, but if you want all the details: http://arXiv.org has the real preprints/articles. At least in the fields covered there, most articles appear here first.

That was very interesting, thank you! You mention this "wasting" thought, which I have too. But it's good to know that despite this, you are still very happy with your choice. I always wonder whether this thought is real, or implanted by in

Oh yeah, this is great! Also interesting: Traveling Wave Reactors ( https://en.wikipedia.org/wiki/Traveling_wave_reactor ). Bill Gates invested quite a lot in TerraPower.

Thanks for your long answer! I agree that Wall St. is not an option. I wouldn't want to develop risk analyses or the next ultra fast trading bot anyway. Not that I don't like thinking about finance, but not all day :) I don't want to make t

There are also two very different group of answers to the questions. However, the point is that the never ending chain of why exists in both religion and science. The claim that religion can provide more than science in this regard is wrong

by davrosthedalek 14y ago
One often hears the argument that science never can give a why, and only religion/philosophy can give that. In my opinion, this is simply not true. In this case, the Higgs mechanism explains, in some sense, why particles have mass (N.B., mo
