How advanced is humanity (Star Trek scale)?

How much has humanity advanced since the first episode of Star Trek? And how far are we from the world depicted in the show? This post tries to answer these questions. 54 years have passed since the first episode of Star Trek aired. Star Trek is set in an advanced [..]

Warp drive could be closer than you think

    Warp drive is, in essence, faster than light (FTL) travel. In 1916 we learned it’s not possible: relativity forbids it, and since we haven’t produced a better theory in 100 years, that knowledge still stands.But while FTL travel is not possible, there’s nothing wrong with effective FTL [..]

4 ways science can support ghosts

  I was in my bedroom at night, trying to sleep without much success, when I heard a strange noise. What was it? It sounded like whining. I stared at the ceiling trying to convince myself the sound had not been that strange; after all, houses make popping and [..]

A poor man’s Her

This tale is very closely based on real facts. I have been working recently on a new project based on artificial intelligence and neural networks. Nothing too fancy: just a proof of concept to check how advanced neural networks really are, especially those involved with natural language and human [..]

Inside the mind of an Artificial Intelligence

  Have you ever wondered how does an Artificial Intelligence think? What are the coincidences and the differences between robots and humans? How do they learn? How much can they learn? I’m going to tell you how a human, a traditional computer and an artificial intelligence tackle the same [..]

Does free will travel back in time?

Imagine that you’re going to raise your hand. Maybe you are in class, or maybe you see a friend on the street and want to beckon him. How much time passes between the moment your brain sends the signal and your hand raises? Guess. 1 second? 1/10th of a [..]

What is a neural network and how does it work?

In this video you can learn -in less than three minutes- how a neural network works.  

The journey from a coffee machine to bitcoin (II)

  In a previous post we learned how we needed a way to exchange goods and services and how our ideas, while growing on sophistication, wound up in catastrophic failures once and again. Until we discovered bitcoin.   Economic system number 6: Bitcoupon (yes, this is bitcoin)   Satoshi [..]

The journey from a coffee machine to bitcoin

How the need for a reliable monetary system leads to the discovery of blockchain through a series of catastrophic failures I remember when we moved to our new offices. They were spacious, bright and squeaky clean, but they weren’t cozy. Going from point A to point B was always [..]

How to discover multiplication using set theory

We have seen in another post that set theory is a good candidate to most fundamental theory of the universe. One of the reasons for it is that the rest of mathematics can be derived from it. Let’s see, as an example and mainly for fun, how to multiply [..]
