We have been¬†mentioning Fusion 360 for the last couple of weeks. I had installed the trial a couple of months ago and got my account updated today. This doesn't seem too hard to use but it will take a little bit of time.... these guys make it look too easy.....ÔĽŅ

So NASA's Eagleworks laboratory has released what they say is confirming evidence for the proof of concept of an "impossible" engine configuration for spacecraft propulsion, a reactionless drive called a quantum vacuum plasma thruster. 

The last sentence of the first paragraph says it all:
"Either the results are completely wrong, or Nasa has confirmed a major breakthrough in space propulsion."

This baby is about to be either further validated or put to rest for good. Either way, let the party begin!ÔĽŅ
Nasa is a major player in space science, so when a team from the agency this week presents evidence that "impossible" microwave thrusters seem to work, something strange is definitely going on

Math Questions  - 
 
Okay I've decided to take my first steps in earnest into abstract algebra. I'm concerned about one of the solutions that the book gives. So the modulo addition group Z_20 the exercise is to find the inverse of 13. The book says that the answer is 17 when it seems that it should be 7 (ie (13+7)mod20=0). I can't find an errata for Gallian's Contemporary Abstract Algebra so...... am I right?ÔĽŅ

Don't let the title fool you. They say "limits" and then give hints at ways around those limits.ÔĽŅ

Problems With Code  - 
 
I am working on solving the Biot-Savart Law equation for the magnetic field around a charged ring of uniform current density. The expression that Mathematica gives is rather nasty, as expected. Notice that the limits of integration are not included in the solution. Mathematica rejects the bounds of integration by silently refusing to even consider a solution (literally, it sits there for several minutes "Running..." and then just stops like nothing ever happened). My idea was that since Mathematica didn't mind handing over the indefinite integral, that I could turn it into a function of theta and manually apply the first fundamental theorem of calculus. For some reason, I can't seem to convince Mathematica that I want this to be a function that I want evaluated at 2Pi and at 0 so that they can be subtracted. Here is the code up to the integration. Thanks in advance for any feedback.

s=1;
m=4*Pi*10^7;
l[Theta_]:={s Cos[Theta],s Sin[Theta],0};
R={x,y,z}-l[Theta];
r=R/Sqrt[R.R];
Deel=D[l[Theta],Theta];
Cross[Deel,r];
Integrand=%/R.R;
B=(m/4*Pi) Integrate[(Integrand),Theta,GenerateConditions ->False]ÔĽŅ

This is a strange idea for a hubless bike to get us thinking about alternative wheel construction. Can you imagine¬†someone showing¬†up to competition with wheels like that?ÔĽŅ

So this is basically what we are working with. We made a short test run to get a better idea of what we need to work on.ÔĽŅ

You bet!

Man, you should have seen it. We took it outside onto the parking lot and Me and Orcun tried to drive it. Dang thing didn't make it 10m and the left front wheel bowed out and the drive chain slipped..... Again.

The good news is that that is just about the worst of it in terms of it being technically competition worthy. She's got a sturdy frame if nothing else.... ÔĽŅ

To reach out and touch a star.....
Introduction
We must capture the spirit of the great pioneers, whose dreams have given to civilization all it has of value. It is that spirit which serves as the lifeblood of our race. Your opportunity and mine to develop what we have been told can never be built must not be allowed to pass us by for another generation. This is our task, here and now. We do not need to ask permission from anywhere and we do not have to buy into the lie that it is not a worthy goal. If you believe, as I do, that this is the time, and we are the people, then join me. Together, we will do all that is necessary to realize the dream of uniting and liberating humanity under the banner of claiming our eternal destiny among the stars.
