https://medium.com/@DaleBeran/4chan-the-skeleton-key-to-the-rise-of-trump-624e7cb798cb#.jmnimypj1 contains the answer to that puzzle.  Be warned: it is a long, thoughtful piece with some uncomfortable ideas for both left and right alike (but not alt-right).

HR 8799 Image Animated With Hot Jupiters January 28, 2017

Posted by stuffilikenet in Awesome, Geek Stuff, Photography, Science.
add a comment

Scientists have detected thousands of exoplanets in recent years, by watching varying brightness as they occlude their stars. This animation comes from direct imaging methods (not radio telescopes), meaning that the telescopes saw the Jupiter-sized planets directly (hot Jupiters are young planets that still glow in the infrared portion of the spectrum).

Jason Wang at the University of California, Berkeley has combined several observations of HR 8799 into the delightful GIF below. This is years of optical data, folks. “In this video you’re seeing real data,” he told Gizmodo1 of the video above. “I smoothed out the orbits so that it’s as if we’re watching [the planets] constantly in real time.”

Open the Alexa app on your phone.

Use the More icon (the hamburger) in the upper left corner.

Select Settings.

Select the device whose wake word you wish to change.

Tap the Wake Word setting.

Select Computer from the drop-down.

You are done.

I would like to point out that Star Trek has so influenced culture that the United Federation of Planets is likely to happen any time now…we just need more planets.  We already have Majel Barret’s voice phonemes.  Now we need Google to sync up, a bit better response to voice meaning (the voice vector thing should help), a truthiness evaluator and bingo! Star Trek in your phone/home/office/laboratory/dungeon/whatever.

Too Much Science to Read, Let Alone Review November 15, 2016

It’s been a banner week for science geeks, nerds, and squints. The locked-in lady gets to at least shout from her prison quietlyGoogle has radar sensitive enough to not only find objects but identify them by their radar signature and perovskite is once again breaking solar-conversion efficiency records.

Ordinarily I would give you a breakdown of each of these nifty developments, but more are coming and I may want to return to these later when I am not pressed for time.  Follow the links above; there are others as well that you will find more well constructed than my chicken scratchings, I’m sure.

Brain-Computer Interface Now in Use at Home!!! November 15, 2016

A 58-year-old woman (“HB”) with ALS has had a functioning brain-computer interface (BCI) for a while now, and is able to communicate (slowly) with the outside world. She was facing total lock-in Real Soon Now, so any device which offers communication ability is welcome.

What it is:

A diagram illustrating the setup and use of the ECoG implant.

Electrode strips at the top laid across her brain like band-aids read faint electrical signals.  With training HB was able to “type” fairly quickly (words per minute, but still).  More work remains to be done on the interfacing software (I am imagining more inputs and a neural network to interpret her thoughts more and more efficiently), and HB is ecstatic to have a way t live in the world.  She would like to use the interface to control a wheelchair, for example, but that is a ways off.

Update: New Scientist has an excellent writeup as well.

What I said about living in a forest meadow?  It’s pretty much the truth. Yesterday I went for an evening constitutional and found some traces of fungus among us:

I’m not sure any of them are edible; after all, the bear doesn’t seem to have eaten any of them.

As far as I can tell with, uh, casual observation, those are Manzanita berries.

A friend gave this to my wife today (the egg mold, not the scotch). I couldn’t wait for breakfast to enjoy it (hence the scotch).  Turns out you can get them sent to your house by tomorrow if you have Amazon Prime.  Hurry up! We can all commune tomorrow morning with pirate eggs.

Better Neutrino Detection Through Beta Decay November 9, 2016

Posted by stuffilikenet in Awesome, Geek Stuff, Japan, Science, Toys.
add a comment

Once upon a time scientists studying the sun couldn’t have the faintest idea of the internal activity of the Sun. One bright (see what I did there) scientist realized that monitoring neutrinos, the massless, chargeless, non-interacting particles that zip through the universe barely interacting with anything at all, might give a useful clue to the machinations therein.  I mean, they knew neutrinos are part of the solar flux,so it’s just a matter of detecting massless, chargeless, non-interacting particles.

Oh, crap.

Well, luckily neutrinos do not remain neutrinos forever; they decay into detectable particles…eventually.  Not often to be sure, as billions pass through a square centimeter every second without leaving any decay particles. Those decay particles can be detected with rather elaborate photomultipliers in a huge cavern in Japan somewhere: “It consists of a tank filled with 50,000 tons of ultra-pure water, surrounded by about 13,000 photo-multiplier tubes. If a neutrino enters the water and interacts with electrons or nuclei there, it results in a charged particle that moves faster than the speed of light in water. This leads to an optical shock wave, a cone of light called Cherenkov radiation. This light is projected onto the wall of the tank and recorded by the photomultiplier tubes.1“ Despite the heavy hardware only a few thousand are detected every year, which should tell you something about the likelihood of a decay event…not very damn likely.

Thing is, the theoretical number and the actual number didn’t match; the experimental result was one-third of theoretical, indicating something must be wrong with the theoretical understanding, or the experiment is crap. It turned out that neutrinos oscillate among three forms (electron, muon and tau) and detectors were primarily sensitive to only electron neutrinos.

Here’s where science gets really intricate; pour another shot and I’ll tell you why. In a distantly-related field, other scientists observed variations in the rate of beta decay of radioactive elements.  Once again, either the data is crap or the theory, and the theory says the decay rate should be constant.  Looking at the data over time, they found that the beta-decay rate matched the neutrino data, indicating a one-month oscillation attributable to solar radiation. Many now believe that neutrino emissions from the Sun are somehow affecting beta decay.

If that’s not strange enough for you then feature this: the same guys who figured this out are going to use beta-decay experiments here on Earth to monitor massless, chargeless, non-interacting neutrinos, and thereby the Sun.

You heard me. Watch the video and be amazed.

The researchers think it could be ready for human trials by the end of the decade.

If it sounds familiar, it might be because Star Trek thought of it first:
