I’m currently hard at work trying to adapt Judea Pearl’s causality theory to quantum mechanics. I believe I’m making lots of progress, maybe enough to come out eventually (soon?) with a paper with my findings. But until then, I have to talk about something, right? So let me mention a device that has delighted me very much of late.
I recently bought an e-reader—Amazon’s Kindle “Paperwhite” $119 model. This model just came out on Oct 1, 2012. Its screen is 6 inches, 2-point touch sensitive, black/white e-ink and illuminated. I absolutely love it.
I bought it mainly for reading research papers in pdf form, downloaded from arXiv or elsewhere. I find I no longer have to make paper copies of research papers I want to read. I just download their pdfs from my computer onto the e-reader and read them there. I find that reading them on the e-reader is more comfortable than reading them on a computer screen, and almost as comfortable as reading a paper copy. But the e-reader beats paper copies in that you can carry a huge number of papers in one lightweight, sleek, compact device, and you can do computer searches on them. My device has a 2 GB storage (some of that is used up by the operating system). That’s enough memory to store more than a thousand papers. ArXiv papers that were written originally in LaTex and turned into pdf, are quite legible on my e-reader, including all the mathematical symbols, and you can change the viewing size.
Of course, I also use my e-reader to read novels. I’ve done quite a lot of that too. I find my e-reader to be a MUCH MORE convenient and pleasant way of reading novels than paper-backs or hard-backs. I believe this for many reasons that I won’t go into here, since this is a blog devoted to quantum computing.
Talking about quantum computing, let me mention that Jeff Bezos, the visionary founder of Amazon.com, is a believer in the future of quantum computers; so much so that in 2012, he invested in D-Wave. So I am proud to use this blog to throw in a plug for his e-reader, although I would recommend it even if Jeff Bezos had no interest in quantum computers. Even if Jeff were a computational complexity theorist, I would still recommend this e-reader.
