Why Does BitTorrent Work So Well?
BitTorrent (BT) is currently the most popular file-sharing peer-to-peer (P2P) clients [1]. Several reports have shown that it accounts for the majority of peer-to-peer traffic, up to one third of the global Internet traffic. However, leaving the media attention aside for one moment, we ask the question: Why does BT work so well? BT attempts to build robustness to freeloading (i.e. downloading w...
متن کاملDoes God so Love the Multiverse? *
Monotheistic religions such as Judaism and Christianity affirm that God loves all humans and created them in His image. However, we have learned from Darwin that we were not created separately from other life on earth. Some Christians opposed Darwinian evolution because it undercut certain design arguments for the existence of God. Today there is the growing idea that the fine-tuned constants o...
متن کاملSo How Does the Mind Work?
In my book How the Mind Works, I defended the theory that the human mind is a naturally selected system of organs of computation. Jerry Fodor claims that ‘the mind doesn’t work that way’ (in a book with that title) because (1) Turing Machines cannot duplicate humans’ ability to perform abduction (inference to the best explanation); (2) though a massively modular system could succeed at abductio...
متن کاملWhy does deep and cheap learning work so well?
We show how the success of deep learning depends not only on mathematics but also on physics: although well-known mathematical theorems guarantee that neural networks can approximate arbitrary functions well, the class of functions of practical interest can be approximated through “cheap learning” with exponentially fewer parameters than generic ones, because they have simplifying properties tr...
متن کاملWhy Is Saline So Acidic (and Does It Really Matter?)
Commercial 0.9% saline solution for infusion has a pH around 5.5. There are many reasons for this acidity, some of them still obscure. It is also true that infusion of normal saline can lead to metabolic acidaemia, yet the link between the acidity of saline solution and the acidaemia it can engender is not straightforward. This commentary draws together the known and putative sources of acidity...
