Can a Singularity Exhibit an Electrostatic Field ? Answered

What is wahh.......  a small black hole ...........  that's a singularity. If you bombard  it  with electrons ( which carry a negative charge ) will the tiny Black hole be attracted to your pet cat.   Cat fur looses electrons easily and acquires a positive charge.

Grammar nazi time

I wasn't sure if this would be considered a bug or feedback. "This author has not updated their profile." "Author" is singular, "their" is plural. It should be something like "This author has not updated his/her profile." The devs could probably make that match the account's gender.

fake nixie tube clock

I was wondering is I could use the same system of using a 7 segment display to wire up a digital clock using el wire since nixie tubes are so much more expensive and limited to small size, or if i should wire it so that it is like a singular l.e.d.  and where could i get smaller metal chicken wire fencing to further increase the nixie tube effect. Sorry for the bad grammar when I get an idea I tend to lack the proper way to describe it even though I can see it plain as day in my head

Arduino Controlled LED "Aircraft Runway" lights?

Excuse me Please: I have a project with a specific need, which I "think" an Arduino and LED strips can meet. The effect I would like is to have the LEDs all dimly lit, and have a single/few run along the length of the strip with increased brightness and returning to the dim intensity once past. think: aircraft runway lights. also, which I think may overly complicate the project, I need like ten strips all running concurrently, each with singular/few brighter LEDs running the length and randomly repeating. does what I explain make sense?

Does anyone have any info or resources that can help me with ODE's and Frobenius' theorem?

I'm studying Frobenius' theorem in school and am having trouble understanding my foreign teacher. His method differs from the one in the book, and I'm having trouble with that too. Most of the examples I've found on the net have been special cases like Bessel's equations or ones that can be solved with Fuch's theorem. (series solutions about an ordinary point, within a radius of convergence) What I'm having trouble with is EQ's that involve series solutions about regular singular points I plan on writing an instructable to decipher how to do this once I understand it better (teaching others helps me learn much faster) so any info would be greatly appreciated.

Okay, so i see religion seems to be a hit here. while I've tried not to add to this irrelevant subject, i think its time the world heard my views. Religion is another form of government with each sector having its own capital, rules, leaders, and history. it is one of the three "G's" by which all wars are fought. (God, Ground, Gold). it holds billions of people fixated on a singularity, a possibility that with proper deduction can be reasoned. While no self respecting Scholar of God (and i mean god of any religion) will denounce his faith, its a quite perplexing subject, for both the religious and secular Humans. In order to truly understand it, you must first examine yourself, leaving aside any beliefs instilled in you. When you feel yourself free from prejudice, open your minds eye to the world around you. everyone has one, and everyone knows how to use it. examine the facts that you already know to be true with those not yet proven by anyone. Please don't misinterpret this post as me siding with anybody. I merely want you to use Deductive reasoning to make your own decisions. there are a few questions you can ask yourself that may help you in your quest.1) Is the juice worth the squeeze? if any religion is right, death brings about great rewards(or penalties) in the afterlife. if science is right, than were just going to die. (gloomy, i know)whichever the case, ask yourself if the effort your putting in is really worth your TIME. (I capitalize time because it is only a concept, an invention much like those on this site. learn to live without it and life will be so much more rewarding. )if you just die, than "...all (your) yesterdays will (light) fools a way to dusty death"- shakespear2) Do you believe everything in your Book (bible, quran,etc.)? if you question even one, than there are definitely more you havent gotten to yet.3) Do you trust your fate to another human?Some Religious leaders are corrupt in every sense of the word. Make a decision.there are plenty more, of which i do not have time to post, but that should be enough topic to discuss for now. I will return later to answer questions and delve a bit deeper. Just remember, "the absence of knowledge is the absence of existence" -Nick Disney (Me!!!!)

How to Go to Maker Heaven

Dear Pier 9, You are a place like no other, and I’m so glad you came into my life.  I was a full time Artist in Residence at the Pier for 4 months, and I doubt I have ever been so simultaneously intellectually stimulated, inspired and intimidated at any other point.  When I came to the Pier I had been living in New York for 8 years, and I had just decided to make a permanent migration back to my homeland on the West Coast.  I’d heard rumors about the rampant culture of innovation in the Bay Area, but I was still totally unprepared for the explosion of creative energy and excitement that is the nerdy artist heaven called Pier 9. Maybe I’m just getting older and less jaded… but in the last few years, I have felt a change in the world, a shift in attitude from angst to optimism, from critique to creation, and I think places like the Pier exemplify this new positive force.  The fact that a multinational corporation like Autodesk has allocated a significant amount of resources to giving the imaginations of a bunch of madcap inventors, artists, engineers and other creatives free reign in a beautiful lab with a bunch of cutting edge machines… well, to me that says good things about the direction of the world.  But what really makes the Pier special, I think, is the fact that all the creativity taking place there is fundamentally motivated by the philosophy of Instructables; by the idea that knowledge should be shared.  I have never encountered a group of people so willing to share their ideas and skills, and so excited to help make other people’s dreams a reality.  And the feeling was really infectious!  Everyone was so ridiculously helpful, that on the rare occasion I had the opportunity to teach someone else a skill, it felt like a treat. That’s not to say that my experience at the Pier was all sunshine and roses.  It was exhausting and draining, and very ego challenging.  When I first arrived I was incredibly overwhelmed by all the new information I was intaking.  I had projects in mind, but those ideas were quickly swept away in the tide of new ideas that arose with every fascinating technology, and possibility I encountered.  Having nearly unlimited options can be paralyzing, and I fell pray to this paralysis many times at the Pier.  One of the pitfalls of having so many amazing minds in one place is that someone always has a new idea that will either revolutionize the project you are working on, or cause you to completely change direction and start working on something new.  That can be great, but if you aren’t careful it can cause acute artistic ADD. I think most creative journeys have a similar arc.  When you are learning new skills, it can take a while for the quality of the work you are producing to catch up with your creative vision.  I definitely felt that way at the Pier.  During my time there, my work ended up going on a journey from two dimensions to three dimensions.  I started out by experimenting with laser cutting.  I am a costume designer, and was interested in creating a wearable mechanical flower that would illuminate and open and close in response to its environment.  My first attempts to create this form felt very flat and lifeless to me, so I stepped away from the flower project and focused on figuring out how to create something much more three dimensional with the two dimensional process of laser cutting.  The result was a costume constructed from laser cut leather and el wire.  After that I decided I was ready to tackle 3D modeling and 3D printing, so I went back to my flower idea, and spent the rest of my time at the Pier testing and developing this form.  It was a really new and interesting process, 3D modeling and prototyping with the amazing Objet printers.  It also gave me the chance to work closely with two other awesome Artists in Residence, Paolo Salvagione and JoeJoe Martin.  It really underlined for me that the most important resource at the Pier is the people.  No matter how many incredible machines you have under one roof, they are only as good as the minds running them.  Noah Weinstein and the other amazing innovators who run the Pier have done such an incredible job of gathering together a diverse, brilliant, exciting, and truly kind-hearted group of people… the place practically buzzes with welcoming creative energy as soon as you walk through the door.  Also, putting relatively self-actualized creators in an environment where there are so many options and resources results in some incredibly interesting glimpses into individual human passion and curiosity.  I might not have fully understood why some of my fellow AiRs were so fascinated by stacking tetrahedrons, drawing graphically detailed pictures of intestinal parasites, or creating physical bodies for virtual bots, but witnessing each artist’s commitment to their singular pursuit was in itself a fascinating and beautiful experience. So much of our lives are spent trying to make practical things happen, it’s an rare opportunity to get to spend a dedicated amount of time just exploring the potential of creative ideas.  I really think that is what Pier 9 is about, providing a place that nurtures our human desire to create, explore and learn… with a kick ass set of resources to facilitate that exploration.  Honestly, during my time there I wish I had been able to let go and enjoy that process more.  It’s not always easy to escape the concepts of deadlines and expectations, but sometimes freeing yourself from those constraints is the only way to create anything truly new.  I very much believe that what is growing at Pier 9 is a new and exciting kind of creative ecosystem, and I hope it will inspire the creation of many more similar environments.  I feel incredibly lucky to have gotten a chance to be an explorer on the frontiers of Maker Land.  Thank you so much Noah and Vanessa.
