Wait a minute...Louisiana? The state that has drive-through daiquiri bars ?
Driving with a Big-Gulp sized Hurricane in your lap (no straw of course, *wink* *wink*), that's OK, but powdered alcohol is irresponsible?
Another symptom of the college bubble - paying more and more for less and less. Even with TAs there is such a flood of students that the grading is overloading the system. Students now can't even get a unambiguous assessment of their capability in a subject.
OK, so now when an employer wants to see grades and transcripts, what should they make of those grades? Was that person riding the coat tails of a smarter partner? Yeah, I'm sure partners would change class to class, but some students are pretty savvy and will know to sit next to the smart kid in class for this reason.
I wonder how many copies of The Anarchist's Cookbook sold this week!
It is not hard to make dangerous things that go boom. Heck, some of the things that I blew up behind my garage when I was 13 would probably send me to Gitmo now. Believe it or not, that doesn't make me a terrorist.
Maybe it would be smarter to examine why people might want to make bombs and kill people, and work to make a world where people don't want to make bombs and kill people, even if the The Anarchist's Cookbook was on every coffee table in the world.
The War in Terror, just like the War on Drugs, will not be won simply by "just saying No". Until human motivations are examined, it will all be a horrendous waste of life, effort, and resources for no gain.
Gosh, I'm sorry. Are any of your neighbors good for anything, or are they all hipsters too?
I guess Instagram and the aviator sunglass industry needs some love too.
The *only* folks who will go for this will be hipsters who would rather talk to an Amazon app on their iPhones than directly with a grubby blue collar contractor.
I have a neighbor who is a licensed construction foreman. When I need work done on my old house, I basically can assist with demo, site prep, and cleanup and he gives me a big break on the bill. He goes home with a case of my homebrew beer when it is all done.
That Amazon can even propose this business model really describes the sad state of affairs of the middle class, community, and humanity's ability to interact face-to-face. We need to put the fucking phones down and talk to each other.
Umm, rocket science is...rocket science?
Combustion CFD is a very difficult area. The problem is that there are so many interlinked phenomena all requiring special modeling methods that one really isn't quite certain of the accuracy of the result unless they can compare it to a physical model test, which is what is frequently done. Simply getting the correct boundary conditions can be very challenging. Failing to apply appropriate modeling and boundary situations leads to a garbage in/garbage out situation, but the numerical solution may look plausibly correct.
CFD is not use exclusively in design work except for very basic cases where the modeling accuracy is well understood. However, CFD for more complicated situations is still useful as it may illustrate behaviors and trends in performance in situations where physical observations are difficult (like in a rocket nozzle). The CFD results can be used to guide and interpret the results of physical testing.
Understanding CFD really requires PhDs who understand fluid dynamics as well as the limitations of the numerical models used. This is true in many industries, not just rocket surgery.

The Dream Chaser's advantage is that it can land on a runway. As long as the runway has sufficient length (Ellington's two runways are both over 8,000 ft in length) then Dream Chaser can land safely. The only real issues would be either a) a failure involving the landing gear, or b) FOD on the runway itself.
The plan for SpaceX's Dragon 2 is also a soft powered landing.
The old model for music distribution:
1. A song gets played on the radio.
2. A listener hears the song and would like to listen to it on demand, so they head down to the album store and buy a CD or record.
3. Listener pays for product, leaves happy! Music!
4. Distribution label PROFITS!!! (though cut has to go to artist, agent, CD/record production, etc.. ).
The new model for music distribution:
1. Listener hears artist's music on Youtube, can play on demand for free, can contribute to artist directly!
2. ??? - sound of crickets chirping -
Not seeing the need for big labels anymore myself. They are trying to coerce money out of a system that is rapidly realizing this new reality. Good luck with that!
Let's have someone running around the office wearing goggles and brandishing a weapon at invisible beasties falling through the ceiling.
Don't see a problem at all with this.
Fluid turbulence is actually well understood and very easy to visualize. Yes, direct simulation of turbulence is very computationally expensive, but good mathematical models for the effect of turbulence in flows have been around for a while and are used in CFD modeling in many industries.
I can actually see turbulence; if I just go down to the river or look up at the sky, there it is. It's complex, but it obeys simple rules and you can actually develop a physical intuition about turbulence.
Not so with quantum physics, at least not yet. I think part of the problem is people rarely get to see the actual experiments that illustrate where quantum physics and Newtonian physics part company. A picture book that illustrates the weirdness physically, maybe some experimental data, would be a help. I recently read a book called "A Quantum Moment" by Crease and Goldhaber; it wasn't bad where it was describing the history of quantum theory, and it actually contains some math, but it just gives up in some sections and starts getting really airy-fairy and weird.
