requires very low vibration so that the ultra fine tip does not drift with time
The vibrations have absolutely NOTHING to do with drift. The drift is caused by temperature gradients in the microscope. One part of the microscope thermally expands/contracts more than another part and the tip and sample will drift. The vibration issue is another matter related to image noise. The feedback used to maintain a tunneling junction has limited bandwidth and excessive vibrations will show up in images as noise. Minimizing vibrations does nothing more than make quieter images allowing smaller features to be observed.
Just what I needed. ANOTHER computing standard to learn. Which standard is next to join the act? Maybe the next one will be more standard than all the other standards.
OK, a VERY rough estimate: Chamber/Vacuum parts $25K Control electronics $40K Pumps $10K computer $2K. Vibration Isolation $4K. So in all, for about $80K you can get set up with a very decent system. Those crazy christmas lights people spend almost that on just a display. For a more wealthy hobbyist, a home brew world class STM system is not far from reach. Or, you can buy a really nice car.
Nah, I don't need that, I have a UHV VT STM (at 3e-11 torr). I designed/built the custom STM head for under $1000. It uses low resonance springs and eddy current dampening for vibration isolation. I am able to resolve not only atoms, but using spectroscopic imaging, I can study the bonding of individual molecules to surfaces. The coolest part is that I can break certain chemical bonds at will. I know chemists claim they've been doing this for years, but to be able to see the bond, and so precisely control it down to the individual molecule is quite amazing. As far as I know, STM is the only technology capable of doing this. Anyways, that's just my pointless rant:)
Oh so many times I've heard this arguement. I'm a researcher in Surface Science and I look at atoms and molecules all the time. Chemical synthesis is very amazing, I give you that. Being able to attatch specific functional groups to complex molecules is no small task. However, the controlled manipulation of these molecules and atoms in physical space is not something that classical Chemistry can do. It's tools developed by engineers and physicists that are now allowing the next generation of nano-technology. STM and AFM are examples of two very powerful (but each with its own weaknesses) tools. The state of the art can be described as cave men tools trying to build a sky scraper. It's not going to happen. But we continue to use these tools and develop them until we have tools good enough to do what we need. Now, back to chemistry. There are now several groups in chemistry who use the tools developed by physicists to study chemical properties. An example is controled chemical reactions on surface step edges, very interesting stuff. Now I ask you, what is the difference between this reaction and the reaction done in a beaker 100 years ago?
The key difference is that we have nano-scale control of the atoms/molecules. I would hardly call mixing two beakers of solution together (OK, a bit simplified, but you get my message) nano-scale control.
Well, for one thing, we can now observe intemediate states and control reactions like never before. We can induce reactions at will and hopefully, (the big one) Manipulate (with control) reactions in a way we could never do before. Imagine building DNA without enzymes to cut and paste like a Frankenstein. COMPLETE control of the nano and sub-nano scale is far from here. But we are making progress like mad. 25 years ago, nobody would have thought this possible, but it's now happening. It's a bit scarey to think of the materials we can make, but it's exciting to think of the possibilities. Sure Chemistry has been good to us, and yes we need it, but there is no possible way that Chemistry alone, as practiced for so long can accomplish what modern Physical Chemistry (or Chemical Physics) can do.
This is what I expect in Canada. You know, the low crime rates and all, the cops tend to get bored. They need something now and then to put some excitement into their day.
Yes, I agree! Very messed up. And yes, calling someone gay is just as common here as anywhere else. I would say the rules are like this: If the person isn't gay, go ahead and "insult" him and call him a gay loser or something like that. If the person IS gay, don't call im gay in front of friends like.... Stay away from that gay guy there. Or something like that. That can get you into trouble. Me, well I don't care if a person is gay or not as long as they don't try force it on me. My philosophy is that well, gay people can't produce children. If they don't feel comfortable living in Canada or the U.S. they should find their own island and start a country. Of course, if we visit 100 years later, they'll all be dead and they will have no offspring to show for it. The way things are now, with gays and aids, they'll die faster anyways.
Yes, Recently The Canadian government passed a bill called bill C250 which makes it a hate crime to disaprove of gays. It's rediculous IMO. Look at this news article http://montreal.cbc.ca/regional/servlet/View?filen ame=mon_humanrights20041011 which says how a person was fined from that very law. If you don't want to read it, the case is as follows... Two men walked into a used car lot. The car salesman told one of those men to "watch out" for his friend there because he is gay. And that's all he did. For that, he was fined $1000. Welcome to Canada, home of the gays.
Freedom of expression is not freedom of speech. Freedom of expression is, for example, expressing your beliefs by wearing a turbin. Or practicing religeous holidays. You can't say that gays should not be permitted to be married. That's not expression, that's speech, and that lands you a $1000 fine or jail time.
I hear a lot of bullshit coming from people out there about how this "publication ban" is a suppression of freedom of speech and how "hypocritical" we are up here in Canada.
Well, fellow Canadian, I have some news for you! Up here in Canada, we do not have freedom of speech as a fundamental right. It is nowhere in the Canadian constitution that citizens of Canada have the right to free speech. In fact, there are laws in Canada that prohibit certain subjects in public. For example, you are not allowed to publically express your disatisfaction with gays and lesbians. Here is an example. This is all possible because of bill C-250 which was passed in Canada.
Section 2(b) of the Charter states that "Everyone has the following fundamental freedoms:... freedom of thought, belief, opinion and expression, including freedom of the press and other media of communication." [www.constitutional-law.net] But we do not have the right to free speech.
Of course, the arguement that the freedom of the press and other media of communication is the same as freedom of speech, the law is often bent both ways. This results in a tangible opression of speech. For example, if someone has done you an injustace, you can not publically tell people about it in Canada as you can be charged with slander in court.
Ok, Ok, I'm laying it on a little thick, but we don't have the same right to free speech as in the U.S. We have a different form of it. Maybe it's for the better, or maybe not. Our constitutions are quite a bit different, but we still enjoy the same high quality of life.
I hope their phone system is built better than their webserver.
I can't RTFA right now, so my only concern is the ability to adapt to different cell phone manufacturers, and what about newer cell phones after purchase. Otherwise, this actually doesn't sound like too difficult a project, but it's the idea that counts. This kind of device can easily be created with a few components and a PIC for under $10.
Good! you sound like an enlightened and informed person. I have a question then. If a person gives a note of permission (with signiture) that a person can use his/her card, are you allowed to accept it? What about permission over phone or if the last names are the same (son/daughter)? I would assume that there must be some way to allow someone else to use my credit card if I so wished. I often lend money with my credit card to friends with on-line purchases, but what if I want to lend my card to my family?
That is quite normal.
A few years ago, a friend of mines mother is a Doctor with her own practice. She uses her visa for buisness purchases, mainly large transactions $1000+ and had been doing that for over a year. One time my friend needed some money for gas so his mom just gave him her credit card. He went to safeway, bought gas and then went in to the store and bought some snacks for his trip. The same day, his mother got a phone call form the credit card company asking if she was missing her credit card. They noticed that my friends purchaces were out of pattern and thought that someone stole the card.
When thieves steal a card, they usually make a few small purchases first to test it out before sucking the card dry. Visa was quick to act on this to prevent theft. It is in their best interest to do this. That kind of action is very normal.
Look what they say:
a medicine or therapy that cures disease or relieve pain relieve pain? that's in the defenition. that's not what you claim.
provide a cure for, make healthy again Make healthy again! Well darn it. Make healthy again doesn't sound like prevention.
When I say cure stroke that means that you either stop it from happening or repair the damage done. That is exactly what cure means. Think about it. I think you would agree that a statement like "you can cure AIDS" is correct. having or catching AIDS is also an event. How is saying that you can cure stroke or cure cancer any different? Fact is: you don't know what the defenition or meaning of cure is.
So you understand: You can cure diabetes You can cure AIDS You can find a cure for the Flu You can cure hemorroids You can cure cancer You can cure stroke.
