A beacon of light in an otherwise gloomy world...

Pigs express their gratitude for humans keeping them alive in large numbers by becoming even more tasty.

Great, now need to keep even more pigs.

So US-Americans really are as crazy as they make themselves look on TV... terrifyingly hilarious :-/

The Varoufakis Effect: 70 billion Euros extra debt?

Must be the financing need to roll over the debt. And some capital flight. Can't be this worse.

The surprising conclusion after 300 billion Euros worth of Greek drama might be that the Eurozone system works.

And I changed my mind again. Looks like they'll end up with the ESM for the coming fifteen years just to roll over the debt. And maybe the Greeks are reducing their expenses too much.

This argument comes up once every while on Lambda the Ultimate. I want to know where the flaw is.

*TMs generating bitstream correspond with a subset of the reals within [0,1], therefore uncountable. Proof by contradiction:*

*Take a countable number of TMs all generating different bitstreams. Construct a Cantor TM which runs every nth TM upto the nth bit and outputs the reversed bit.*

*Now I have established there are uncountably many TMs.*

(The argument is that every bitstream is a unique real in the set [0,1]. Since every TM can be seen to be represented by that real, we can use Cantor's construction to prove that there are uncountably many TMs.)

Where does it go wrong?

Well. I am still not pleased either. I thought that without loss of generalization one can *choose* an enumeration. Someone convinced me otherwise, but now I have doubts again.

Oh great. Real physicists actually agree with my uninformed musings.

Leading on from the last post that discussed Informational Structural Realism as a way of looking at the world and doing away with both digital and continuous views of reality I thought I'd share this essay

This essay won second prize in the Foundational Questions Institute contest

I first encountered

The image / GIF below depicts a representation of a Spin-1/2 fermion that needs to be rotated through 720⁰ in order to return to its original state and was lifted from Wikipedia: https://en.wikipedia.org/wiki/Spin_(physics). It was mentioned in the essay a few times as an example of of a property - which the forces of nature treat differently depending if it spins one way or another - that suggests reality is continuous and analogue.

For +John Baez. I reduced the number of colors and ran a compression algorithm on the gif. Please give all credits to GIMP (Gnu Image Manipulation Program), a great piece of free software.

Same for Egan. You guys are good at this...

My estimate of what went wrong here:

1. The load was top heavy.

2. The land cranes were placed on two pontoons, effectively 'doubling' the degrees of freedom leading to a highly unstable design.*

3. Land cranes aren't capable of handling the horizontal forces which come with working on water.

4. The pontoons lack the stabilization mechanism found in the pontoons where water cranes are build upon.

*) A boat has six degrees of freedom, but you can also look from the front and simplify it to a 2d-system of a mass attached to bars. With a second pontoon you go from two (already unstable) to four bars (unmanageable with land equipment.)

This is what you get when land engineers try to work on water. Pretty lousy results.
