MTS is the worse company in Canada (IMO) when it come to overcharging and nickel and dimming. I'll stop here, but know that I could write an awesome rant. ~:-)
The force required to deflect/bend a beam is proportional to the cube of the thickness. Each time you fold the paper you make it twice as thick, and therefore 8 times stronger.
I thought they said it was cold? It was -38F when I left for work this morning. Check out the weather for Winnipeg Canada @ http://www.theweathernetwork.com/weather/camb0244 Note: -40F =-40C and 1C ~ 1.5F.
Spinning resist on paper works well. However, as the paper is flexed (after deposition) the resist begins to crack. It might be better to use cardboard. Incidentally, this process would not have worked well in the past. Typical resist thickness was 0.2-2um. The roughness of paper is around 0.5-3um (depending on the paper). Now, many people are using thick resist (as molds for electoplating for example). These resist can be 10-20, 20-60, 40-80 micron and thicker. Some SU-8's can be 100-800um thick (a 4" wafer is 500um thick). I've also sputtered Chromium onto paper. Unfortunately, the layer wasn't thick enough to conduct (I just wanted to see if it would work). Also, you can use a sharpie maker en lieu of resist for a lift-off process. Semiconductor equipment + office supplies = fun stuff!
Here in Canada, I've notice that newly constructed homes are build using polyeth tube en lieu of Cu. Anyone know if any houses in the USA are plumbed with polyeth?
This is the real deal people! Stop the presses! Push the financial crisis aside! Set the terror level to RED, and panic panic PANIC! Ahhhh! (Sorry, I didn't get much sleep last night ~:-)
How do you know someone's normal heart and breathing rates? They're not seriously going to take an avg are they? Also, increased heart rate & breathing are common for people with high blood pressure, and/or overweight. So does than mean every American is a terrorist? Good job, people! Also, if people are stressing about generating a false positive, they will generate a false positive. Just a few thoughts.
I'm guessing that/.'ers know that the LHC is not going to form a black hole. In case you don't here's the math.
Mass of a intermediate black hole = 1000x the mass of the sun
Mass of the sun = 332,946x the mass of the Earth
Mass of the Earth = 6x10^24 kg
Therefor mass of black hole = 2x10^(33) kg
Mass of a proton = 1.67x10^(-27) kg
The crushing force of a black hole is caused by its density, a large mass in a small volume (1000x the mass of the sun in a 1,000km diameter ball -> ~size of the Earth).
So flinging around 40 or so protons in a 27km diameter tunnel is not going to destroy our solar system (or reshape the galaxy).
I have yet to see an opto-actuated opto-switch. I haven't been paying attention to the opto domain for a while, but this was the case the last time I was searching. Anyone here know a potential (pure opto) switch technology?
Twice a year, we can expand out small talk to the DST/ST debate. If you live in the US there isn't much point to DST. However, the further North you live the more convenient DST becomes. Here in WPG, in summer we get 16.5 hours of sunlight at our peak. It is more convenient to have the sun go down at 10pm instead of rise at 4am. Perhaps originally, it saved some energy as people used less incandescent lighting. With the information age (cable TV, internet, etc..), I image that less energy, as a percent of total consumption, is used for lighting. Any thoughts?
Just buy a cheap laptop, and/or an USB stick. Put your pix on the USB key and put it in your checked bag. Nuke the laptop b4 you come back, I've typically cross the US border 3-4 times a year. I've never had a problem with carrying a USB key along with my camera. I've only brought my laptop across once, and had no problems. The thing I get questioned on is my underwater camera housing, but they just ask what it is. Then they say cool, and ask if their camera will fit. ~:-) To which I say "No, each housing is made for a specific camera." Hope this helps.
The real question is where you can make the structure strong enough to withstand a tsunami. Physics work against you. This will most likely have to be built on the ocean floor, and have to be hight enough to break a tsunami wave. Deflection of a beam is proportional to (length)^4. Deflect to far, and SNAP!
2 points.
Getting the intensity of 326 suns on my roof isn't going to happen.
GaAs wafers are not cheap. Here is are some recent prices, 3" n-type GaAs are $125 each (per batch of 25), 4" n-type Ge are $344 each (per batch of 25), 4" 100) n-type Si are $35 each (again per batch of 25). Note: 3" (4"?) is as big as you are going to find a GaAs wafer. The growth method does not allow for larger wafers. Also, this price for Ge seems a bit high.
Either use progressive marking (later tests are worth more marks). Or allow student to repeat tests. My Electronics II prof did something like the latter. There was a test every month (4 in total plus final exam). Each test had 5 sets of of short questions. You selected the 3 sections you knew the best. In order to pass the test, you needed to get 85% or better on your sections. If you failed a test, you had a chance to redo them on the final exam (the questions were modified). This seemed to work well. Each test is small enough such that you didn't feel swamped when studying. This did make for a long final if you are a lazy student. Typically, there are 2 ways to borderline pass a course. You either have a very good understanding of half the material, or half an understanding of all the material. Our prof's reasoning was this "I'd rather you had a good handle on some of the topics,as opposed to a half-assed approach one everything in this course. Why? Because one day one of you may design my pacemaker, and I want the damn thing to work!"

And get Shaw high speed internet! I only have internet through Shaw. I get my local TV news, and hockey from some good old rabbit ears.

it just heated up too fast and expanded too quickly. ~:-)

Then their probability will increase to 50%! j/k.
Into the atmosphere? Good plan!

Ok so I got some time b4 I need to break out the popcorn for the show.
Give us a case of beer, and we'll call it even.

The amount of gold in a NIC is minimal. It would literally take tonnes of NICs to get 1oz. of gold.

Build a faster computer. User's expands simulation parameters (which bogs down the faster computer). Rinse. Repeat.
