Many, many times.
One semester I took an elective Intro to Theoretical Physics class which was very math intensive. I spent hours looking at very difficult problems, sometimes I could have those "aha!" moments on my own, other times I had to go to my professor's office hours. That was the...
I have no idea about the commercial/general aviation sector as that's not my expertise (I work on spaceships, and I'm not that far out of college). However, I do know that there were a lot of jobs at Boeing that were canceled when I was applying because of delays due to manufacturing issues (at...
I don't think that AE is any more difficult than EE. I'd say that AE would be harder than ME (which was part of the reason I went the AE route). AE and EE are difficult in different ways. AE typically uses some higher level math, but it can be physically easier to comprehend. AE's also tend...
(I'm an Aerospace Engineer by the way)
If I were to do it all over again, I would take a bunch of controls classes as either an AE or EE. I saw a lot more jobs available for EEs than I did AEs when I was looking, but that might not be the best way to pick a major.
But yeah, you can get...
Going by what I remember from the movie, they never said what it was that gave him propulsion, or what exactly came out of his hands when he was shooting things with them. The important part of his technology seemed to be the immensely energy dense power source located on his chest.
I...
IMPORTANT- Don't freak out go to grad school if you don't want to (I did this and ended up leaving grad school without a degree because I didn't want to be there)
I graduated in Aerospace Engineering without ever having an internship in anything other than some civil related internships (no...
Move. Simple enough.
I grew tired of grad school in engineering for various reasons, and the whole point of me going to grad school was to get a job in the private space industry. I found out I didn't need a graduate degree for that, and bailed. I moved across the country to do it as well...
To add to that, I wonder if you could take their turboprop set up, change the gearing, and drive a ducted fan with it. I don't know if you'd gain much from that modification or not.
It's been awhile since I've studied the subject, so don't take 100% of what I say to be valid.
JetCats, from what I know, are reasonably popular engines for RC aircraft, and thus have lots of hours on them, and I've heard of just about every variety of engines made by them except for...
Update:
The chicken thighs I recently got for whole foods, while still good according to their expiration date, smelled horrible when I opened the package. I had to toss them out and eat out instead. I also noticed that the bacon that I bought there only a few days ago actually expired in...
Yeah, the walmarts here are entertaining in their own ways. The first time I went to one when I moved here there was an old lady, wearing a dirty wedding dress (that was turning gray), in a wheelchair, pulling herself forward with her feet and hitting herself in the head while laughing...
Okay I'm jealous now. I'd love to have fresh eggs since I eat them every morning. I have to settle for supposed Omega-3 eggs. I've never had 'em fresh before.
I was upset because where I used to live there was a farmers market that sold fresh meat (but I couldn't afford it on a grad...
I don't think the meat had multiple stickers. What was weird was that it wasn't tough. It had almost no texture at all. There was no noticeable grain, like the muscles of the animal had never been used, it was almost homogeneous "meat substance" in the shape of strip/rib meat.
...I also...
I'll have to seek out a good market, because I've been wanting to fool around with meats aside from the standard beef/chicken/pork. I enjoy a good piece of lamb here and there but have never cooked it myself. Also maybe venison or something more exotic would be good for a change.
Las Vegas, demographic guaranteed to be weird. The difference between the poor and rich part of town is about a 1 mile, and I live on the boundary.
Snobby? I don't know if I'd call Whole Foods snobby except for a select few of the people that shop there and think they poop greener than...
See, I like buying cheap supplies like gallon sized bags and all the mundane things at walmart. I'd never buy furniture there or beef probably ever again unless something miraculous happens.
I thought their fruit/vegetable selection was good until I got sick off an avocado there that...
There are other grocery stores (like Trader Joe's and Von's) but Trader joe's selection is pretty limited and Vons doesn't have a good selection of beer, cheese, or vegetables/fruit. I like to grab random strange veggies and fruit that I haven't tried before and I just can't do that at a...
I have to admit, I liked the fact that when I moved out west here, there was a super walmart about a mile away from my apartment, and a walmart grocery the same distance in the opposite direction. However, I recently bought some steaks, frozen salmon filets, and scallops there that made me...
Ah, it does look like they are cut out of that green husk. It was so good though! Not at all like the dried coconut shavings I'm used to seeing.
I actually ate all of the flesh while I posted this...:uhh: Now I want more!
The white outside was relatively soft, and there was a thin, woody husk that was difficult to cut with a sharp knife. It had a pattern kind of like 3 eyes, but not like what I'm used to seeing (3 distinct, round, black eyes), instead it was kind of a much harder, triangular shape that I avoided...
I've also found out that coconut water can be used as an intravenous fluid, straight from the coconut :eek:!
I'm picturing some poor guy laid out on a bed with a coconut over him and a tube going straight from it to his arm.
Yeah, I've seen pictures of watermelons like that before, which made me think that it's some kind of "manufactured" variety. In fact, they look like this:http://www.healthydude.com/Resources/thai_coconutsa.jpg [Broken]
I couldn't find information on why they look the way they do with a...
The last time I remember opening a coconut was when I was younger than 5. I remember really disliking the taste. I also remember the coconut being round, and brown. I've always disliked the taste of dried coconut you find candy made out of, but regardless I decided to purchase a "white...
Was the life expectancy short because of diet or because of other factors?
I've run across a lot of experiments supporting low carb diets (which necessarily must be high in fat content because only so much protein can be processed by the body), and other things involving ketosis.
Here's...
I felt soo good today because after I cooked an awesome meal I managed to get myself to bleach the kitchen counters/stove and then did ironing.
I mean, I did some serious ironing. The mound was about 4 feet high and i got through it all in an hour and a half. I didn't hate it as much as I...
The base of the pyramid is composed of grains, so the obvious response that everyone I knew growing up was to eat lots of bread, pasta, etc. because it's good for you.
Why is a lot of fat bad for you? There have been cultures that subsisted mainly on fat and protein with very little vegetable...
Going by what has been classically considered "healthy" (lots of grains, etc.) did nothing but add fat all around my body and make me want to pass out after eating meals (sometimes the urge was irresistable).
I've experimented with and am currently doing a diet that is only fresh meat, veggies...
I could see getting a shave and the whole nine yards at a barber if I felt like being pampered, but 99% of the time I just want to buzz it all and then go relax in the shower. That and I love lathering up the shaving cream myself. It's relaxing.

One of my best investments has been a set of decent quality electric trimmers. When I get tired of my hair being too long, I just break them out, pick a guard, and go to town. They're only $20, and they usually last me at least a year or two depending on the quality.
Can you believe that you...
I finally moved into a place by myself, and although I got away from (sometimes) messy roommates, I'm learning how messy I am myself. It's a struggle just to do the basic things sometimes, like just keeping the kitchen clean after whipping up some dinner, and keeping the laundry manageable...
You guys are encouraging, but I know there has to be someone on this board who has done this!
Zz, I'd hope so. I think I'll have a solid understanding of engineering by the time I enter physics grad school if that's the route I choose. Knocking out shop drawings to standard will be no...
I was curious if anyone had experience with going for a physics PhD after having a decent engineering career. I've been considering the possibility of this, and am currently working and refreshing my memory on the physics I've learned (and eventually teaching myself more) in some of my free...
Oh, haha, it lists lbf as the thrust measurements. That should be read pounds force, as opposed to pounds mass. English units can be confusing that way. The way I calculate mass in english is either in Slugs or Blobs, because the whole lbm thing confuses me.
That sounds reasonable for C_D...
I would say yes, as flying at that speed at an altitude of only 700ft (dense, sea level air) requires a lot more thrust when the pressure is a fifth or tenth of that at altitude.
What I'm curious about though is your units, you have thrust written as Nm when it should just simply be N. Nm is...
I looked around for factor of safety information, and http://cat.inist.fr/?aModele=afficheN&cpsidt=4913559 mentions that the standard factor of safety for aircraft is around 1.5, meaning the structure is designed to be 50% stronger than it theoretically needs to be. However, the forces on an...
I'm not 100% sure about the terminology of VD but http://www.gps.tc.faa.gov/glossary.html says it's the design dive speed. I know that you do not want to exceed the Vne which stands for velocity (never exceed) because exceeding that means that the airplane's frame could become overstressed and...
If you want to work for a big company like Boeing, apply for internships about 12 months in advance, seriously, and as soon as you possibly can. Right around the start of your senior year in high school, they should probably have internship openings for the summer following your graduation...

Fixed pitch helicopters will have no collective (rotors rotating equally on each side to provide more/less lift) or cyclic (rotors rotating unequally on each side to provide tilt in any direction, be it forward, backward, or left and right). The tail rotor...
For my case (Aerospace Engineering), fresh out of college, I had the opportunity to do space vehicle structures (if I remember correctly, space shuttle components) because I had some experience in undergraduate in composite materials (an elective). I also had potentials with Boeing working on...
I once explained the idea of lagrange points to someone, and how if you placed an object equally distant from the Earth and sun, but separated from their axis such that the 3 points made an equilateral triangle, the object would orbit nothing. That really blew their mind and they were...
