We are not hitting one physical limit. We are hitting several physical limits. Feature size, dielectric effective thickness, poly-Si depletion and band separation are the ones that I know aboot. We are seeing diminishing marginal returns, due to physical limitations.True, shrinking you feature size will give you more devices for the same size die. However, shrinking the feature size also increases power consumption. It does not increase efficiency as the article claims. When the feature size is shrunk, the gate dielectric thickness has to be reduced accordingly. As the dielectric shrinks, leakage (via tunneling) increases. This is why the idle power has increased dramatically over the years. Switching to HfO2 dielectric has helped. There is however, another problem, namely the poly-silicon contacts. A transistor is all about charging and discharging capacitance. The capacitor you want to charge and discharge is the one that's under the gate. All other caps are parasitic. The devices today are switching so fast that the poly-Si is being deplete of carriers. This causes an increase in parasitic capacitance. The next problem will be band splitting. As you reduce the length of the gate, you are using less atoms. As the number of atoms drops, the bands of each individual atom become "visible". It becomes difficult to tune the band gap as the bands split (to which band do you tune?). Hence the multi-core processors. Multi-core is the only way the industry can keep following Moore's rule.
First, check with your doctor before beginning any diet or exercise program. There are many ways to reduce unwanted pounds. Eating sensibly is number one. If you simply eat less calories, you will lose weight. This will shrink you stomach, but it will not shed (much) body fat. However, this means that whatever food you do eat must be good for you. Excess sugar (soft drinks), salt, and fat (deep fried foods) should be avoided as much as possible. Eating 5-10 servings of fruit and veg will help. Fruit is mostly water, but contains a lot of vitamins and minerals your body needs to function. The actual size of a serving is never clearly defined. I typically, treat a serving as half the size of my fist, but I do lean more towards 10 rather than 5 servings. Nutritionists are constantly finding new things in food. So I try to keep the variety high. Also, try drinking a cup of water before every meal. Drink plenty of water (6-10 cups a day). The signal for thirst and hunger are the same. You may think you are hungry, but in fact you are thirsty. Try drinking a cup of water when you feel hungry. wait 5-10 minutes, if you are still hungry, then you probably are hungry.
Running on a treadmill, elliptical, arc trainer will burn fat. Depending on your age, training will vary. Get a trial membership at a gym. They typically, offer an assessment, and a beginner program. Then cancel after the trial is done, and workout at home. The trainer will help you find exercises that work for you. If you are in your 30s, eventually you will want to be burning 500-1,000 calories per session. This is a lot! Shoot for 300, and work you way up. 500-750 should be a target, but you should be able to do a session at 1,000. You won't know this value unless you're running on a machine. Which you can use in a gym.
Yes, that's true, but that's not the focus of the article. The article is aboot replacing electrical lines on the PCBs. The biggest bottleneck in a PC is the front side bus. This is the connection b/w the memory, the HDDs, and the CPU. If you could switch these types of connections from electrical to optical then you could increase the communication bottleneck b/w the chips. The next step would be faster RAM and then faster HDDs, next a faster CPU, then a faster bus, and the circle continues.
One bit of material can be switched b/w four states. Thus Base 4 logic is possible. However, the article indicated that each cell will be used for 2 bits. In this arrangement capacity is only doubled.
That's why no one really care aboot the RIAA. Artists will begin to offer their music to the people via the internet. Groups of artist can get together and post songs. Initially, the songs can be free and low quality (128kbs) with web ads paying for the site. Once pop songs are found (via download numbers), then higher quality songs can be sold via an online store. Who needs producer? If you do hire one on a contract, and let him go the minute they are no longer useful.
Flame me if I'm wrong! ~:-)
It makes more sense to go to asteroid and pick up a couple of tonnes of Pt ore, and other rare earth material. If we can find (or have found) such an asteroid.
"It is enough if we think about the 19th century's slavery related laws: could we claim that it was immoral for a black person to break the law when he/she sought freedom?"
Well put!
Law's need to evolve with society. Sometimes they do. From my perspective, we seem to be diverging.
Political parties should also do the same.
Reading Word is almost useless (for me since I use pages, numbers, and keynote for work). I'd be interested if it could read PDF. The I could scan in a few things before leaving, and read them on the plane. Can some1 please make a PDF writer for the kindle. I can't do it because I'm not a programmer.
Cheers, KiwiCanuck
High dollar items are worlth fixing. For Mp3 players and digcameras, it's typically not worth it. You can buy a new one for the same price and get a better version, or buy a cheaper version with the same functionality of the one that broke. Although, I must admit that on more than a few occasions I spent some time fixing broken electronics that I should have replaced. I only did this because I had the extra time to spare, and I was curious about the inner workings. However, most electronics repair companies in my city are closing down, b/c everyone is buying new to replace the broken.

How about adding heath & well being, international policy, finance and grammar to the list. While your at it add Canadians.

Opps! I mean Benefit/Cost to high for a mouse. ~:-)
Cost/benefit of a mouse is too high. Please show me a touch screen LCD that costs $10.
are soon departed.
I could have sworn that our laws of physics didn't exist prior to the big bang. Thus, making it impossible to determine pre-bang events.

There are no [good looking] girls!
That's insane. How are you supposed to value a growing software company in 10 days. WoW! The people who write these laws have no business sense.
Seriously, headlines like this should not make it to print.
How funny would it be if they missed? ~:-)

This is the scariest statement ever made.

forced me to switch to firefox a "long" time ago. This news is just a reminded of why I use as little MS products as possible.
Does trolling count as patent development?
Yes, but the way it is currently worded will generate more hits, and thus more ad. revenue.

Change the name to the "I'm feeling stupid button". Link it to a trojan, and problem solved. ~:-)

How dare they bribe a non-gov official! But seriously, I'd love to see Penguins take over the world.
