Search for creation and anihilation operators in second quantization. It's quite simple. I give you a field with some particles populating some modes, and applying the creation (annihilation) operator gives you a field with one more (l

"In their trial run, Julia was much faster than R. But I objected, because random walk is a sum. Thus one can generate the entire process in R as vector calls, one to generate the steps and then a call to cumsum(), e.g." You misse

I use ipython notebook daily for data processing and interacting with simulations. Works great. The problem is that I need SOMETHING that lets me draw diagrams and write equations by hand,

I have a surface pro 3 that I use exclusively for note taking. I'm a physicist and hand written notes are absolutely crucial. The fat iPad style stylii have way too thick a tip for anything useful. Surface Pros, Lenovo tablets with dig

Huh? What there suggests he's familiar with the theory of quantum measurement?
756.
by gaze 11y ago
The author doesn't seem familiar with quantum measurement. Yes of course the measurement apparatus disturbs the state... There's plenty of theory for this and how it works into computation.

From this you'll end up with the closed form in terms of the golden ratio. Might as well use that.

Grinding wheels wear from left to right. You dress it to a certain diameter and then particles come off the left part before they come off the right. That way SOME fraction of the width is at the proper diameter. This is why you never ever

Maybe it has something to do with all the garbage that the verge loads every time you load the page?

I enjoy the interactive development experience, but the idea of stashing all this code around a running system in a large team in a way that makes it hard to tell exactly what you have strikes me as dangerous.

I think we can all agree that LispWorks is really, really expensive.

Yeah, you're right. I apologize.

Can we PLEASE just work on writing a decent native GUI library for lisp? Making QT work better? Something?

You should first understand currying. If I have a function f :: A -> B -> C -> D, every time I apply an argument, as in f a where a is of type A (b :: B, c :: C, ...), you get a new function back of type B -> C -> D. Read ::

You should get over it. It's just syntax... and it's there for a reason (Makes more sense for curried functions, and it's a holdover from logic where you say that if you have a nameclass, you have an object that sense a qname

I think just as much as it's important to have intuition is to have a healthy relationship with your intuition. Knowing when to trust it and when not to. Intuition often happily leads you very far down the wrong path. Math can, too, ob

I've noticed that this is the perspective taken by most people up to date on this stuff.

I'm sorry, if you're going to break the laws of physics, please be professional enough to know VNA stands for vector network analyzer.

They really haven't shown that. See boixo's paper and troyer's work.

Yeah but if you're a company the price of something is completely different. Maybe that server needs really excellent realtime performance for some really specific business need (finance?) I just don't understand how 500 bucks is

Holy hell why is this still so expensive? 64-bit Lispworks is $3000 when visual studio professional is $1200? Visual studio community is FREE for COMMERCIAL USE in small teams! What student has 500 bucks to throw at something that can'

He doesn't seem to know THAT much about fractals. Not more than you could pick up reading about them on weekends for a while.

Could anyone hope to tell the difference at the time?

We don't see why it's not possible, we're just not sure exactly what it's gonna look like. Martinis believes it's gonna be surface codes. My group believes it's gonna be cat codes. Or something. Who knows? It&#

You know, I hear people use this excuse to justify bad behavior a lot. I once heard a bike messenger tell me that brakes gave him a false sense of security so that's why he didn't have a brake on his fixed gear bicycle.

In a damned material! If you have the right terms giving a coupling between the electromagnetic field and phonons, yes, yes that's what happens. No, in free space, there is no such coupling.

Is there any formalization of how to invert a formatter, or is this just something they're figuring out in code as they go along?
