Time Teleportation

I guess this should not be a surprise...given the space-time continuum. However, for some reason it is harder to contemplate time entanglement than space entanglement.

In space entanglement, I can measure either entangled particle, and the other will be the same.

In time entanglement it makes sense that I can measure a particle in the past, and its future partner will have the same value...but this also implies that if I measure the future of a particle, I force its past into the same state. Is there a way to change the past hidden in here?

The Fourth R.

Reading, wRiting, aRithmetic, and algoRithms.  My wife and I were just brainstorming about this: how coding should be the next "basic" skill.  Of course, someone was ahead of us and posted this .  It is awesome to see Mozilla Hackasaurus referenced in this article.  It is a small world. In the early days of the printing press, scholars wrote the books; the press was simply used for production (see this article ).  As time went on, "average" people became familiar with the medium, and used it for their own messages.  We are at just that point with the Web.  Software Engineers write the code, and the Web distributes it.   Software Engineers are the algoRithm scholars of today.  They won't be for long.  Soon algoRithms will be taught starting in elementary school, along with the other three R's.

Connectome as a Book

Your Connectome is a map of your brain.  Every neuron, every synapse. I am only a few pages into Connectome, but was intrigued by a sentence: "Human DNA....has three billion letters....would be a million pages long if printed as a book."  The companion question, "How many pages for the Connectome?" might be answered later in the book, but I thought I would take a shot at it here. Here is the punchline: Your Connectome book is 6.7 million times longer than your DNA book. That human DNA is about a million pages is not too surprising, although it probably is not optimized. According to quora there are between 1500 and 1800 letters per page.  I am going to use round numbers, namely 2000.  Then, the 3x10^9 DNA letters would actually be 1.5 million pages.  But this is very wasteful.  Even using just ASCII we can encode four DNA letters per character, so the book should really only be about 400K pages.  And, this book is much more interesting; in...
