FREE - AMULLETTE AFLAME ON KINDLE!!!

Posted by Rasheedah Prioleau on March 30, 2014 at 4:00am

Hey BSFS!!!! 

I just got Amullette Aflame back from the editor and wanted to give you all a chance to get it Free before the virtual launch May 1st.  

FREE Sunday March 30th - Tuesday April 1

http://www.amazon.com/Amullette-Aflame-Princess-Rasheedah-Prioleau-ebook/dp/B00D2XFHJG/ref=sr_1_3?ie=UTF8&qid=1396096635&sr=8-3&keywords=rasheedah+prioleau

 After three years in prison without trial, Amullette is given the opportunity for parole if she agrees to raise a stolen child named Mikaya as her own.  Another condition of parole is marriage to a high ranking soldier of the Universal.   As fate would have it, her selected spouse is her ex-fiancé, Admiral Semaj Kroan.

Adjusting to her new life is easier than she expected as she falls in love with Admiral Kroan and adores the little girl the Universal has asked her to raise.  However, as Amullette and Kroan begin to build a beautiful life together they must face making the ultimate sacrifice to get Mikaya back where she truly belongs.

Wild Space Saga

Posted by Brandon Hill on March 29, 2014 at 2:51pm

Hey there, BSFS!  

You know, it has come to my attention that I NEVER posted any updates to my comic here!

::le gasp!:: 

My friend and co-writer, Terence Pegasus and I have created a new Wild-West-in-space themed webcomic called WILD SPACE SAGA, a three-arc epic series in the far-flung future.  

The plot goes a little something like this: 

***

The Future.

Far From Earth.

Mankind has spread to the stars; Earth has been lost. Civilization has fallen and arisen.
Since the devastation of the Imperium Wars, the danger of internal conflict among the Alliance of free worlds has become a constant threat, while the Second Imperium, a cruel mockery of the fallen old civilization, licks its chops for more worlds to increase its growing war machine.
Faced with the superior technology of the Imperium, the Alliance knows that the only defense against the Imperial war machine is unity.

But that hope is bleak.
And an ancient evil is coming.

***

Sound epic?  It is! You like Gunslinging?  We got it!  Sexy catgirls (and boys)? Got that too!  Epic space battles and giant freaking robots?  We've got you hooked up! High stakes plot with the future of life as we know it on the line?  Oh, yeah!  

So the only question left is, is your body ready for awesome?

Of course it is!  

I should have been sharing this with you all for awhile now, but it completely slipped my mind for some reason (Don't judge me.  :-P  ).  But that means you're all in luck, as we have a good backlog of pages since this past August, when it began.  Our first story arc, "The Last Warship" is well underway, So come on down and check us out!  New Updates each week!  And we have big things in store!  

Wild Space Saga

Also, to double your pleasure, we have new concept art and updates posted on our official DeviantArt page.  I'll be sure to post some of our new works here as well, so follow my posts here on BSFS. But if you want to keep up with us a bit more closely, and especially if you have a DA account, devwatch us here:  

Wild Space Saga - Deviantart

If we've piqued your interest, thank you very much!  We hope you love the work we've done.  And all we ask is that you share the love if you love it!  We want our viewership to grow like the itchy spot on your foot that you told no one about.  So come on down for adventure, and stay for the free baklava.  And as we like to say, we hope you'll come along with us to follow the Northwest Passage!  

See you soon, space cowboys!

Cause It's Cap...

Posted by Reginald L. Goodwin on March 28, 2014 at 6:00am

...and, it's Friday! One more week to geek on "Winter Soldier." I'd buy on Fandango: after the east coast nuclear winter, people will be stir crazy from telecommuting and need to get out...and see real people again.

 The analysis below is the reason why you shouldn't take a physics person to the movies with you...just kidding, and my wife sadly has no choice in the matter. We'll behave, promise. Just don't ask questions like these.





At the end, Cap throws his shield at the Winter Soldier – because that’s what Captain America does. But wait! The Winter Soldier just catches the shield and throws it right back at Captain America. The real cool part is what happens when Cap catches the shield. The impact is strong enough to push him back a little bit. Is this enough to get an estimate for the mass of the shield? I think so.



Sliding Back

This is really a multi-part problem. First, the shield is thrown by the Winter Soldier. I don’t really care about the throwing motion. Next, the shield moves through the air to Captain America and collides with him. This gives him some recoil velocity. However, Cap is standing on the ground such that his recoiling body is slowed down to a stop by friction.



It might not seem to be the best place to start, but I am going to start backwards. Let’s look at Captain America sliding after the impact with the shield. By estimating the frictional force and the sliding distance, I can get a value for the recoil speed after the impact.



In this first problem, I can just consider Captain America as a block with some initial speed moving across the ground. Here is a force diagram while he is slowing down (after the impact).


The forces in the vertical direction must add up to zero since Cap doesn’t accelerate up or down. This means that I can find the force the ground pushes up on him:


Why do I need this force pushing up (usually called the Normal force)? If I use the typical model for sliding friction, the magnitude of the frictional force can be determined by:

Nano Fingerprints...

Posted by Reginald L. Goodwin on March 26, 2014 at 5:00am
The process of producing anti-counterfeit nano-fingerprints based on randomly distributed silver nanowires.
[1] Silver nanowires (AgNWs) are prepared by the self-seeding method and an amorphous silica shell is coated on the surface using tetraethyl orthosilicate (TEOS).
[2] Fluorescein isothiocyanate (FITC) and rhodamine B-isothiocyanate (RITC) are attached covalently to the surface of the pre-formed silica shell by allowing the formation of covalent bonds between the silica surface and 3-aminopropyltrimethoxysilane (APTMS).
[3] A photolithographic process is used to inscribe the direction and target markers on the surface of the PET film. The orientation marker (“KAIST”) can be used to determine the correct direction of the PET film. The target marker (“X”) has an empty space in its central region where AgNWs are loaded to generate fingerprints.

Counterfeiting is a steady and increasingly important problem that occurs in nearly every trade and industry. Recognizing the difficulty in distinguishing counterfeit goods from genuine products, new nanoscale technologies are being developed to prevent and identify this illegal practice. Using dye-coated one-dimensional (1D) nanowires, researchers at the Korea Advanced Institute of Science and Technology (KAIST) in South Korea have demonstrated that randomly distributed nanowires can generate unique and simple barcode patterns readily applicable by many to anti-counterfeiting.



Reporting in Nanotechnology, nanoscale fingerprint patterns are generated by simply casting fluorescent dye-coated silver nanowires onto a transferrable flexible polyethylene terephthalate (PET) film. The direction and target markers ("KAIST" and "X") are patterned by a photolithographic technique to provide positional information for identification and the nanowires are cast onto it. Then, using an optical microscope, the resulting unique fingerprint patterns can be visually authenticated in a simple and straightforward manner, as shown fully in the figure above.

Nuclear Quantum Computers...

Photon-shaping technique could lead to "nuclear" quantum computers. (Courtesy: iStockphoto/polygraphus)

A way of modulating the waveforms of individual, coherent high-energy photons at room temperature has been demonstrated by researchers in the US and Russia. The advance opens the way for new quantum-optics technologies capable of extremely high-precision measurements, as well as the possibility of <>quantum-information systems based on nuclear processes. The new approach could also be useful for those doing fundamental research in a variety of areas, ranging from the role of quantum phenomena in biological processes to fundamental questions in quantum optics itself.



The technique was developed by Olga Kocharovskaya, Farit Vagizov and colleagues at Texas A&M University and the Kazan Federal University. Their set-up bears some similarity to a Mössbauer spectroscopy experiment. A sample of radioactive cobalt-57 decays to an excited state of iron-57, which then decays by emitting a 14.4 keV "soft" gamma-ray photon. This photon can then be absorbed and re-emitted by a nearby stainless-steel foil containing iron-57. Because of the Mössbauer effect, no energy is lost in the recoil of the stainless-steel lattice and the photon is emitted at 14.4 keV with very little spectral blurring.



As the foil absorbs and re-emits the photons, it is vibrated at megahertz frequencies. By making clever use of the Doppler effect, the team is able to shape a single photon into a double pulse and even a train of ultrashort pulses. This makes it possible to use the gamma-ray photons to encode quantum information in a "time-bin qubit" – quantum bits in which information is encoded in terms of the relative arrival time of pulses.

#TheWalkingDead Season #Finale Predictions #amc

Posted by Gerald Dean Rice on March 24, 2014 at 9:30pm

The following is a list of people who will die:

  1.        Maggie
  2.        Sasha
  3.        At least 2 guys in Darryl’s group
  4.        Some guy you see in the background once

 

Now what’s going to actually happen? After the events following the group’s hasty exit from the prison, surprisingly few people died. For a show that has no compunctions about killing main characters, there’s been too much build-up for all these main characters to make it. Combo that with the fact that Terminus looks quiet (one might say almost too quiet) that can only be foreshadowing that something grizzly is going to happen.

RGDX...

Posted by Reginald L. Goodwin on March 24, 2014 at 6:39am

A little something to do while vegging on the couch (nothing on the "boob tube" except COSMOS, really).



Controlling a lab from home



The Remote Control Glow Discharge (RGDX) is a plasma that you can control from the comfort of your browser. YOU have control of the entire experiment including the gas pressure inside the tube, the voltage produced by the power supply that makes the plasma, and the strength of an electromagnet surrounding the plasma. You can perform experiments from any computer anywhere in the world!




In 2002, we began developing plasma sources for educational purposes and one of our devices won 2nd place in the National Apparatus Competition sponsored by the American Association of Physics Teachers. In 2003, we began controlling our plasma sources by computer for a plasma exhibit in a science museum. The progression of this has led to remote control of a plasma from any location by anyone with an internet connection. This type of control could serve as an experimental component of an online physics class or for a school that typically does not have plasma physics equipment.



As with all other Science Education Department labs, the RGDX has been developed in large part by high school and undergraduate interns.



The Remote Glow Discharge Experiment was officially released to the public on 3/12/2014. The story can be found here.

Children's Home...

Posted by Reginald L. Goodwin on March 23, 2014 at 5:51am


Established in 1847, the Children's Home provides a range of services and programs giving hope and healing to abused and neglected children in the Hudson River Region. The Children's Home served 397 children and their family members last year. The Home provides a full range of residential services including campus-based care, community-based group homes and boarding homes, and independent living apartments. It also provides regular foster care and intensive therapeutic foster homes.



Throughout our 167 year history, the underlying mission of the Children’s Home of Poughkeepsie has remained the same: The Home is dedicated to providing a safe and nurturing environment that improves lives and empowers at-risk children and families in the Hudson Valley and surrounding communities.



I did this presentation on Saturday, 22 March at the behest of the local Alpha Kappa Alpha alumni chapter. I have done such presentations before. I was more than happy to do it.



It was a focused audience of five young men and three young women. They participated well, and at least a few of them said they were going to purchase electronics snap kits from "The Shack." I came away encouraged and inspired by the curiosity of these young people in spite of their challenging circumstances. Especially in an era of error and pseudoscience propagated as alternate "truth" more outreach like this is needed: these are the "meek who will inherit the earth" and will need the tools to manage it.



Physics teachers: all the links in the embed are active, including those in the pictures of slides 8 and 12. If you want the Power Point version with all the "bells and whistles" of this embed, email: physics4thecool@gmail.com. Please attribute the source. My reference to Korea on slide 4 was a quote from "The Smartest Kids in the World and How They Got That Way," by Amanda Ripley and not meant to be derisive: the Korean children spend 16 hours a day in school M-F and 8 hours on Saturday. They are brilliant via focus and immersion.

 I used parts from Electronics 101 and Electronics 303 kits purchased from Radio Shack. Apparently, Radio Shack only carries the Electronics 101 snap kit. I'd try their service number for the more advanced Electronics 303. However, Amazon carries comparable manipulatives: SC-100,  SC-300 and SC-750. Good luck.

The Moon's North Pole...

Posted by Reginald L. Goodwin on March 22, 2014 at 12:02pm


On 18 June 2009, NASA launched the Lunar Reconnaissance Orbiter (LRO) to map the surface of the Moon and collect measurements of potential future landing sites as well as key science targets. After two and a half years in a near-circular polar orbit, LRO entered an elliptical polar orbit on 11 December 2011 with a periapsis (point where the LRO is closest to the surface) near the south pole, and the apoapsis (point where LRO is furthest from the surface) near the north pole. The increased altitude over the northern hemisphere enables the two Narrow Angle Cameras (NACs) and Wide Angle Camera (WAC) to capture more terrain in each image acquired in the northern hemisphere. As a result, the Lunar Reconnaissance Orbiter Camera (LROC) archive now contains complete coverage from 60°N to the north pole (except of course for areas of permanent shadow) with a pixel scale of 2 meters.



The LROC team assembled 10,581 NAC images, collected over 4 years, into a spectacular northern polar mosaic. The LROC Northern Polar Mosaic (LNPM) is likely one of the world’s largest image mosaics in existence, or at least publicly available on the web, with over 680 gigapixels of valid image data covering a region of the Moon (2.54 million km², 0.98 million miles²) slightly larger than the combined area of Alaska (1.72 million km²) and Texas (0.70 million km²) -- at a resolution of 2 meters per pixel! To create the mosaic, each LROC NAC image was map projected on a 30 m/pixel Lunar Orbiter Laser Altimeter (LOLA) derived Digital Terrain Model (DTM) using a software package called Integrated Software for Imagers and Spectrometers (ISIS). A polar stereographic projection was used in order to limit mapping distortions when creating the 2-D map. In addition, the LROC team used improved ephemeris provide by the LOLA and GRAIL teams and an improved camera pointing model to enable accurate projection of each image in the mosaic to within 20 meters.

Peer Review...

Posted by Reginald L. Goodwin on March 21, 2014 at 5:00am
Timberwood Park, San Antonio, TX: Caveat emptor

Yesterday (17 March), researchers from the Background Imaging of Cosmic Extragalactic Polarization (BICEP2) telescope at the South Pole revealed that they have detected the first evidence for the primordial B-mode polarization of the cosmic microwave background (CMB). The astronomers claimed that the primordial B-mode polarization signal – which is related to primordial gravitational waves that flowed through the early universe – is the first direct evidence for cosmic inflation and has been measured to a statistical certainty of 3σ. Now, cosmologist and Perimeter Institute director Neil Turok, who worked on an inflationary model of his own with Stephen Hawking in the 1990s, urges caution and says that extensive experimental confirmation is necessary before BICEP2's results can be considered as evidence for inflation.



"If...and it's a big if...this is true, it would be spectacular evidence for what happened at the Big Bang," Turok told physicsworld.com. While he agreed that at first glance, the BICEP2 observations are in keeping with inflation "as suggested over 30 years ago, wherein space–time would resonate with the aftershocks of inflation and would ring like a bell", a closer look at the discrepancy between the new results and previous data from the Planck and WMAP telescopes is what worries Turok. Indeed, the tensor-to-scalar ratio of 0.20 that BICEP2 measured is considered to be significantly larger than that expected from previous analyses of data. But the BICEP2 researchers said in their press conference yesterday that they believe certain tweaks could be made to an extension of the ΛCDM cosmological model that could make the two results agree.



"But these tweaks would be tremendously ugly....and in fact, I believe that if both Planck and the new results agree, then together they would give substantial evidence against inflation!" exclaims Turok, further explaining that "[we] must be careful before we treat them as true".



"Extraordinary claims requires extraordinary evidence." Carl Sagan.

 Even though Tuesday's announcement was exciting news, and I really want it to be true, it might not be. After the Scientific Method, this is the rigor of peer review and the necessity of it. Without it, we march down the primrose path of pseudoscience and created entities like the Discovery Institute ("intelligent design") and World Science Database (which purports that the Special and General Theory of Relativity have been "disproved"  despite yesterday, I was discussing superconducting quantum interference devices - SQUID's). Both organizations are of "sounding brass and tinkling cymbal" to quote Corinthians. The Science Channel - when it's not suggesting UFO close encounters - promotes the tagline "question everything." We really should.

SQUID...

Posted by Reginald L. Goodwin on March 19, 2014 at 2:58pm
Micrograph of a SQUID amplifier, made at NIST in 2012, that is part of a circuit used to read signals from arrays of superconducting sensors. Small currents generated by the sensors are carried and amplified in the coils, which create magnetic fields detected by the SQUID (two small squares in the center of the image).

From humble beginnings in a series of accidental discoveries, SQUIDs have invaded and enhanced many areas of science and medicine, thanks, in part, to the National Institute of Standards and Technology (NIST).



SQUIDs—short for superconducting quantum interference devices—are the world's most sensitive magnetometers and powerful signal amplifiers, with broad applications ranging from medicine and mining to cosmology and materials analysis.



Physicists from around the world celebrated last week* to mark the 50th anniversary of the first journal paper introducing the SQUID, published in February 1964.

Celebrants heard about the use of SQUIDS to measure brain activity in Finland, discover mineral deposits leading to a large silver mine in Australia, and detect faint light from the early moments of the universe from telescopes all over the world.



SQUIDs measure magnetic fields based on quantum properties created when a superconducting circuit loop, in which electricity flows without resistance, is interrupted with one or two short sections of resistive material. The current across the resistive section varies predictably, based on the strength of the external magnetic field, making the device an exquisitely sensitive detector of magnetic fields. Typically, SQUIDs need to be cooled to cryogenic temperatures below 4 kelvins (-269 degrees Celsius) with liquid helium.



The SQUID was invented at Ford Scientific Laboratories in the 1960s but was further developed at NIST (then called the National Bureau of Standards). James Zimmerman co-invented one type of SQUID (the RF-SQUID) and coined the term while at Ford, before joining NIST where he worked in the 1970s and 1980s.

AfroFuturism?

Posted by Arnold L. Johnson on March 19, 2014 at 1:21pm

I will ask the question.

What is Afrofuturism?, the crux and purpose of it? Is it a perspective or a cultural designation?

My interest is on material culture, cultural immersion, perhaps an ideal that embraces us all but not necessarily a racial/cultural identifier.  So, what's the vibe?

I ask because I am an artist, interested in design (material culture) that we live with day to day. And I'm tired of waiting for the future to come, thinking about contrasting with the present.
