The statement is absolutely correct when we talk about an 11 K change in temperature
Thank you for repeating verbatum what I said.
The only difference between the Kelvin and Celcius scale is where the zero i put
once again. I stated the conversion earlier. Nothing new here. I think you mean where you place the reference temperature, not "zero i put".
When we talk about a temperature difference it's completely irrelevant where you stick the zero
Once again repeating what I've already said.
If this is representive for the state of education in the US then we are so going to 0wn you
First off, I am not from the United States and no, you are not going to "0wn" me. you are not going to "0wn" anybody. If you think the state of education in the U.S.A. is very bad (I'm not saying it's great) then why is that country academically successfull when it comes to the "real world" problems.
A mouse or rat with a human brain would be a gold pot for research. Today, Neuroscientists are studying brain stroke by causing them in mice and watching how the brain responds. Studying plasticity and treatment techniques. Unfortunately, we don't want to cause a stroke in a test subject that is human just to study stroke.
Testing in animals is just an approximation to the human brain. Although a very good one. An animal such as this with human cells would optimal to study the effects of drugs, addiction, stroke, brain trauma, virtually any ailment that affects the human brain.
Are we killing people? no! These are mice and rats that we've been euthanising for a long time. They will not be intelligent, they will likely not function as well as normal mice (instincts and such would likely be absent). I think they would most likely be empty shells that have to be fed and watered to keep alive so that a few months down the road, we can use them to find a cure to stroke.
P.S. Note, this is my normal sig. I did not change it for this post. I think it fits well!
I understand that it's not that big a deal for this discussion, but I'm very concerned about mistakes. It's simple mistakes like this that result in a multi million dollar space vehicle becoming space garbage. Not enough fuel or not enough thermal insulation because someone conveyed the wrong conversion can be costly. That's an extreme example, but it illustrates my point.
Mistakes are expensive. I'd rather learn and not make mistakes than learn from my mistakes. When I see an error (be it my own or someone elses) I do something about it. Let them know. I'm not doing it out of arrogance or vanity, but my "mental dissorder" of being afraid of mistakes. And no, my learning curve doesn't suffer from this attitude. IMO it improves in the long run.
wrong.. 11K is not 11 degrees C.
11K is -262 degrees C. What I think you meant to say is that a difference of 11K is equal to a difference of 11 degrees C.
I can't possibly take that article seriously, the references are a joke. Only 4 references for the whole thing! The first one only references a journal but no author, no title, only a date. That's like saying for more information about computers, see slashdot.org. The fourth reference has a science fiction title in it "Star Trek: The Next Generation". Give me a break. The part saying "It's entirely possible I've made one or more mistakes of order-of-magnitude or greater significance" is not very reassuring. If you want to learn about physics, my first hint to you is not to use a "paper" like this, which has the feel of something that a high school student might write. Go and read a real book. I'm not trying to flame you, just wake you up.
If you want 3D and color on a hand held graphing calculator, I think you are missing the point. The fact that we have these graphing calculators now is a real folly of our education system. People feel that they don't have to learn mathematics because their calculator does it for them. This is going to get you into serious trouble down the road. I've been through it. My first year university I bought me a shiney new TI-89 thinking that calculus will be a breeze for me.
It sure was! Just plug in my integral for x^2 and wow, symbolic calculations. Let's fast forward 6 years. The problems I encounter in physics are not the most complicated, but complicated enough. I've quickly learned that you can't trust the result of these calculators. In fact, 90% of the time, the calculator can't even do the computation. Simple problems on paper are impossible on my Ti-89.
My advice: buy a $5 add/sub/mult/div calculator and save yourself alot of headache. Learn the math inside and out and visualize the graph yourself on a piece of paper. Not only will you understand what's going on in the mathematics, but you will also save yourself a few bucks which is better spent on beer.
My Ti-89 now is used solely as a paperweight. Seriously, worst purchase I ever made.
Well, this has got to be a true role model for movie geeks out there. I remember in elementary school that reciting The Grinch Who Stole Christmas was impressive. I could actually recite the whole thing word for word at 10 years old. If he could do that for LOTR, that is, word for word. I'll be impressed.
I live near Albert Kolk here in Southern Alberta and I didn't actually see Albert's plane, but I do personally know who he is. I heard that his plane had serious damage to the fuselage and that Albert figures that he can fix it and save the fuselage. I've had a chance to fly with him before, perhaps I should have taken it because I for some reason don't feel comfortable flying in a plane that he would have repaired. Although, if the repairs are successfull, then it would show that the system isn't so bad after all.
For your information, an SEM (Scanning electron Microscope) can not resolve atoms. In fact, it isn't even close. You need about 1000x more resolving power than an SEM to see atoms. Techniques are available now to resolve atoms, such as the AFM (Atomic Force Microscope), and it's predecessor the STM (Scanning Tunneling Electron Microscope.) My field of research involves STM and you should know that it's not an easy technique. You are limited to conductors and semiconductors and even then you usually need Ultra-High Vacuum to image surfaces as any oxide film will interfere with the technique. A few highly innate materials such as gold, platinum, and carbon can be imaged in atmosphere.
Bottom line, don't go around saying you've seen 1 atom thick objects in an electron micrograph. It's not true.
Perhaps you don't understand my point. I mean that the number of Watts required to pump water for irrigation is so large, that the sun may not be a viable source.
Why would this benefit the poorest people? It still takes energy to pump the liquid. If they are poor, they need power to pump water and in case you don't know, water is heavy. Ever tried lifting a barrel full of water? The only benefit over conventional pumps is that it has a long lifetime and fewer parts. The cost is probually much higher and the energy to run it is not free.
On the other hand, if you can run this off solar power (assuming you can generate enough power), this would be great!
I find the list in the article incomplete. Where is Physics?
I would assume Physics would be quite high. It's not an easy subject and there aren't very many of us. The demand, however, is there and so the pay should be good.
If IT Jobs are really earning more money than there must be a few things going on. Firstly, The industry may be seeing increased profits, Secondly, There may be increased demand for IT Professionals. Thirdly, There may be a decreased supply of IT Professionals.
The salary paid to those working is not just something that is nice to have high. It is calculated from the state of the system. If the pay is bad then do something about it. Sometimes the only thing you can do is find a different job as there are too many workers in the industry.
Also, the industry can regulate this more if IT people want more money. Take the Medical Profession for example. They place a limit on the number of accepted students every year. If CS education did this as well, then the decreased supply (I don't think the demand is going anywhere) will force employers to pay the workers more money. On the reverse side, not as many people would have jobs. This is almost like the question on Socialism vs. Capitalism. If you want everyone to be working and be marginally content, then don't expect alot of money. Judging from this article, that is not what people want but infact the Capitalistic prespective in that they want more money.
Watching the press conference on NASA TV, It appears they were having problems with the batteries that fire the chutes overheating. The guy in charge of return said that they tested the batteries to be safe for 5 degrees hotter than the probe experienced on re-entry. I'd say that that's a mighty small margin of error.
It was also said that the Hyugens probe due in January, of older design, doesn't use batteries and will not be faced with this problem. When will NASA learn?? Keep it simple and don't fix it if it isn't broken.
Rutan can barely escape the atmosphere. I don't think his little "space pod" of a toy rocket will ever make it into orbit. The amount of energy required is immense. Just look at the space shuttle, It's a cock pit strapped onto a giant fuel tank. What you really need is an all purpose space craft (maybe like Rutan's??) to be docked at the ISS for these little missions so that you don't have to come into orbit for every little mission.
Fusion power is available today to heat your homes, put electricity on the grid and more!
You may think I'm joking, but I'm serious. In case anyone hasn't noticed, there is a HUGE fusion reactor located exactly 1 AU (Astronomical Unit) from your position.
The sun!
Just like in a small fusion reactor, you need some way to turn the radiant energy into useful energy. Why would we want to make another fusion reactor when we still can't fully take advantage of the energy that is radiating out into space every night.
We have a few billion years of fuel left so why not spend the $$ on developing more efficient means to use that energy, rather than building a lab reactor.
What do you expect? To see little aliens holding up signs?
The images were aquired ussing the ESA's VLA telescope with ground based observing. You can see details of the surface of the moon from the ground. Don't criticize the images unless you understand them. From your post, I am not convinced you understand what was involved in taking these images.
Did you read the article? The images were aquired by the ESO's VLA Telescope. Which is an array of smaller telescopes. Bottom line is that this is Ground Based Observing.
I can also see that you know nothing or very little about astronomy. Atmospheric aberration is a big problem in ground based observing. There is really no solution yet, but there are solutions comming up soon (Infa-Red measurement corrections). The fact that surface DETAILS of a moon of a foreign planet were observed is quite amazing. I would wager that this experiment performed in space would provide images quite a bit crisper.
I don't understand why you want to drag the HST into this, other than to discredit it without reason. As for replacement, I ask, WHY? You don't throw away something that works for something new. You can keep both. I don't see why Americans think this way. Keep the HST and let research continue in parallel with newer telescopes.
Step 1: purchase the Ark of the Covenant on eBay
Step 2: travel up Ararat with your purchase
Step 3: Seek the power of the Ark to find the Ark
Step 4: use the Ark to ask for another flood in which you use the other Ark to live (repaired) provided the first Ark works and you find the Ark with the Ark in the first place.
If you can store potential energy in a spring (nano-springs?) Why not make use of this concept in modern cars much as hybrid cars do. Use braking to "wind-up" the spring, then energy from which can be used to give a good boost to acceleration.
Of course, the question is how much energy can we store in a spring and is it practical? Perhaps some research is required.

Now they need to make the power supply and electronics smaller, and the display bigger (at least 8.5x11). Add the ability to be able to roll it up or fold it and put it in your pocket and I might think about getting one.
