“Spooky Action at a Distance” Makes Sense—in the Quantum World

Einstein never liked quantum mechanics but each transistor in your cell phone is a quantum device

In last week’s podcast, “Enrique Blair on quantum computing,” Walter Bradley Center director Robert J. Marks talks with fellow computer engineer Enrique Blair about why quantum mechanics is so strange. The discussion turned to why Albert Einstein, a brilliant but orderly mathematical thinker, did not really like quantum mechanics at all and what we should learn from that: https://episodes.castos.com/mindmatters/Mind-Matters-110-Enrique-Blair.mp3 The discussion of Einstein and “spooky action at a distance” (his way of describing quantum particles’ behavior) starts at approximately 27:45. The Show Notes and transcript follow. Excerpts from the transcript: Robert J. Marks: Albert Einstein didn’t like quantum mechanics or certain aspects of quantum mechanics. Dd he die thinking that quantum mechanics was a fluke? Enrique Blair (pictured): That’s an…

Could Carbon Computing Make Computers More Environment Friendly?

As a key component of life forms, carbon is abundant and energy efficient

Carbon, a very abundant chemical element, is one of the building blocks of life, partly on account of its stability. It is a minimalist element, compared to the silicon used in computing today: … carbon dioxide is is a small gaseous molecule consisting of two oxygens both forming a double bond with a single carbon while silicon dioxide is a massive behemoth of a molecule made of huge numbers of alternating oxygen and silicon atoms and is more commonly known as sand. S. E. Gould, “Shine on you crazy diamond: why humans are carbon-based lifeforms” at Scientific American (November 11, 2012) But there’s something else about carbon. As George Gilder puts it, carbon-based life forms, like humans, consume very little…

Will Your Next Water Outing Be on a Crewless Watercraft?

Crewless ships get much less attention than driverless cars but they are much more obviously practical

The new robot Mayflower, scheduled to set out across the Atlantic from Portsmouth next spring (tracing the voyage of the historic Mayflower in 1620), is one of a growing number of autonomous vessels. It must make many decisions based on its programming. Like most crewless ships at present, the Mayflower Autonomous Ship (MAS)’s mission is information, not transportation. That mission includes gathering data on plastic pollution and marine mammals, according to IBM, the technology partner of U.K.-based marine research organization, Promare. Here are some reasons autonomous (crewless) vessels offer advantages: ➤ With 70% of Earth’s surface covered by water, only 20% of which is mapped, there are too few humans trained to do the scientific, commercial, and patrol jobs. Much…
