By E J Spode – We need to talk about trust and its place in the fabric of our lives. Trust seems to be in short supply these days, although we have no choice but to rely on it.
We trust schools and babysitters to look after our children. We trust banks to hold our money and to transfer it safely for us. We trust insurance companies to pay us should we meet with some disaster. When we make a large purchase – such as a house – we trust our solicitors or an escrow company to hold the funds until the transaction is complete. We trust regulators and governments to make sure these institutions are doing what they are supposed to be doing.
A good way to wrap our minds around ‘blockchain’ concept is to think of its most famous application: Bitcoin. And the best way to think about Bitcoin is not in terms of coins at all but rather as a giant ledger.
Bitcoin is just one version of the blockchain. The fundamental technology has the potential to replace a much wider range of human institutions in which we use trust to reach a consensus about a state of affairs. It could provide a definitive record for property transfers, from diamonds to Porsches to original Picassos. It could be used to record contracts, to certify the authenticity of valuable goods, or to securely store your health records (and keep track of anyone who’s ever accessed them).
But there’s a catch: what about the faithful ‘execution’ of a contract? Doesn’t that require trust as well?
What good is an agr’ement, after all, if the text is there but people don’t respect it, and don’t follow through on their obligations? more> https://goo.gl/rW7huO

By Margaret Wertheim – The world is full of mundane, meek, unconscious things materially embodying fiendishly complex pieces of mathematics. How can we make sense of this? I’d like to propose that sea slugs and electrons, and many other modest natural systems, are engaged in what we might call the performance of mathematics.
Rather than thinking about maths, they are doing it.
In the fibers of their beings and the ongoing continuity of their growth and existence they enact mathematical relationships and become mathematicians-by-practice. By looking at nature this way, we are led into a consideration of mathematics itself not through the lens of its representational power but instead as a kind of transaction.
Rather than being a remote abstraction, mathematics can be conceived of as something more like music or dancing; an activity that takes place not so much in the writing down as in the playing out.
Since at least the time of Pythagoras and Plato, there’s been a great deal of discussion in Western philosophy about how we can understand the fact that many physical systems have mathematical representations: the segmented arrangements in sunflowers, pine cones and pineapples (Fibonacci numbers); the curve of nautilus shells, elephant tusks and rams horns (logarithmic spiral); music (harmonic ratios and Fourier transforms); atoms, stars and galaxies, which all now have powerful mathematical descriptors; even the cosmos as a whole, now represented by the equations of general relativity.
The physicist Eugene Wigner has termed this startling fact ‘the unreasonable effectiveness of mathematics’.
Why does the real world actualize maths at all? And so much of it?
Even arcane parts of mathematics, such as abstract algebras and obscure bits of topology often turn out to be manifest somewhere in nature. more> https://goo.gl/ifKV2Z
