About the Fuss: Is Bitcoin really important?

Posted by in categories: bitcoin, cryptocurrencies, economics

This afternoon, an automated bot at Quora suggested that I answer a reader question. Quora is essentially an “Ask the expert” web site. It is the world’s largest, cataloged and indexed Q&A repository.

This is the question I was asked to answer:

Some pundits believe Bitcoin is a fad, while others seem to feel that it is better than sliced bread. I like sliced bread.* Is Bitcoin really that cool? —Or is it just a lot of Geeky hype?

One other columnist answered before me. Normally, I pass on an invitation, if a question has already been answered. But in this case, the individual answering the question has yet to see the light. He has wandered into the Church of the Blockchain, but he just didn’t realize that the man sweeping the floor is the prophet.

Non-Linear Junction Detectors (NLJDs)

Posted by in categories: computing, mobile phones

The ORION™ Non-Linear Junction Detector (NLJD) detects the presence of electronics, regardless of whether they are radiating, hard wired, or even turned off. Electronics containing semi-conductor properties return a harmonic signature the ORION NLJD can detect when radiated with RF energy. An NLJD detects physical properties, and not energy emissions. Therefore, devices that contain circuit boards and their components, like cell phones, video cameras, and microphones can be detected by the ORION NLJD.

How does a non-linear junction detector work?

The NLJD antenna head is a transceiver (transmitter and receiver) that radiates a digital spread spectrum signal to determine the presence of electronic components. When the energy encounters semi-conductor junctions (diodes, transistors, circuit board connections, etc.), a harmonic signal returns to the receiver. The receiver measures the strength of the harmonic signal and distinguishes between 2nd or 3rd harmonics. When a stronger 2nd harmonic is represented on the display in red, it indicates an electronic junction has been detected. In this way, a hand-held ORION is used to sweep walls, objects, containers, furniture, and most types of surfaces to look for hidden electronics, regardless of whether the electronic device is turned on.

Russia Launches Telescope Into Space To Map The Cosmos In ‘Outstanding’ Detail

Posted by in categories: cosmology, evolution

It would be the first-ever map of the universe in high-energy X-rays, Nature magazine noted.

Such a map “will be essential to solve the core questions of modern cosmology,” Roscosmos said in a press release. “How do dark energy and dark matter affect formation of the large-scale structure of the Universe? What is [the] cosmological evolution of supermassive black holes?”

The agency added that the telescope, which has reportedly taken decades to develop, is expected to find about “100,000 massive clusters of galaxies” and millions of supermassive black holes ― many of them new to science ― over a four-year survey period.

Before You Take a Mail-In DNA Test, Brace Yourself for Family Secrets

Posted by in category: biotech/medical

Like many people, Barbara Greenberg wasn’t looking to unlock any deep, dark family secrets when she spit into a tube a few years ago and sent her DNA off to be analyzed. “I was just curious to see if I would find anything a bit interesting,” Greenberg says.

And at first, there were no real surprises; she was, as expected, 100 percent Eastern European Jewish. But she’d check back into her account now and then, looking for new matches to distant cousins, and eventually someone else popped up—an unknown female relative with a DNA match significant enough to indicate it was likely a half-sister.

As Greenberg and the other woman began communicating, their shared story took shape. Although the other woman had very little information about who her biological father might have been, Greenberg says the timing, location, and certain clues the woman’s mother had given over the years indicated that they did, indeed, share the same father.

Milestones in space travel: An illustrated timeline

Posted by in categories: engineering, space travel

We’ve come a long, long way since the U.S. first launched fruit flies into space in 1947. Since then, we’ve sent astronauts to the moon, installed an International Space Station in orbit and landed spacecraft on Mars. In the past couple of decades, private corporations such as SpaceX and Blue Origin have joined the fray and will likely play instrumental roles in aerospace engineering and space exploration. Here’s a look at some major advancements we’ve made in spacecraft technology and space exploration milestones over the past seven decades.
