After the acquisition of Phenix Systems, 3D Systems has been slow to roll out its metal 3D printing technology, an issue raised in a class action lawsuit against the company. Nevertheless, the company has been making progress and, today, 3D Systems announced the availability of their newest system, the ProX DMP 320.

Some people take the new year as an opportunity to contemplate their goals; Alan Lightman, writing in the January issue of Harper’s magazine, takes the opportunity to contemplate the creation of the universe.

It’s a topic too vast and unimaginable for most of us to wrap our brains around, but Lightman brings his considerable skills as both physicist (he teaches at MIT) and novelist (“Einstein’s Dreams”) to introduce us to a “small platoon of physicists” who focus on figuring out such things as what happened at the very first moment of the big bang, whether time or anything else existed before it, and exactly how we distinguish the future from the past.

And they expect, sometime in the next 50 years or so, to have some real answers.

I administer the Bitcoin P2P discussion group at LinkedIn, a social media network for professionals. A frequent question posed by newcomers and even seasoned venture investors is: “How can I understand Bitcoin in its simplest terms?”

Engineers and coders offer answers that are anything but simple. Most focus on mining and the blockchain. In this primer, I will take an approach that is both familiar and accurate…

Terms/Concepts: Miners Blockchain Double-Spend

First, forget about everything you have heard about ‘mining’ Bitcoin. That’s just a temporary mechanism to smooth out the initial distribution and make it fair, while also playing a critical role in validating the transactions between individuals. Starting with this mechanism is a bad way to understand Bitcoin, because its role in establishing value, influencing trust or stabilizing value is greatly overrated.

The other two terms are important to a basic understanding of Bitcoin and why it is different, but let’s put aside jargon and begin with the familiar. Here are three common analogies for Bitcoin. #1 is the most typical impression pushed by the media, but it is least accurate. Analogy #3 is surprisingly on target.

In a not too distant future, societies of all countries come to rely on an intricate network of artificial intelligence devices designed to bring efficacy to man’s life. Yet, man continues to devour himself in useless wars. A strong political hierarchy now divides all powers into three factions, and A. I. devices rapidly gain ground as efficiency becomes a priority.

As social revolts grow worse everyday, authorities seek ways to control their citizens. They decide to carry out a series of tests that will determine not only whether some crucial powers can be transferred to non human entities, but also whether man is ready to yield those powers.
