If the question is: "Will we have nanotech soon?"... we already have it.

If the question is: "Will we have working nano-bots soon?"... it's a vain hope, but there's a 50:50 chance of it happening in the next 50 years.
 
Not really Nano-bots but something within that realm. I am doing a research project about NanoMedicine. So far, I have found information on filtration masks and bandages. To think that they use nanotechnology on Kid toys.
 
We already have nanotech... the question has to be more specific... are we talking merely applied nano-tech or, say, wide-spread commercial-level or mass-market nanotech?

The problem with nanotech is that it's a much hyped and much abused term...
 
A basic quesetion...hmmm..I will have to get back at you on that one.. ( I could barely explain it to my teacher, with all my stutter words trying to prove it with my mixed information.He told me that it has to do with Biology then find the pros and cons.)

What does that even mean?

It's something to do with Atoms and Ions. The whole Protons and Electrons thingy. I think it's called that because at Atom is one nanometer in diameter, either that or it's several thousand times smaller.

EDIT: I didn't realize there was a whole other page. Why can't this damn website take you to the last page of the thread automatically?
 
No, I know full well what nanotech is – I’m (studying to be a) biotech engineer, and any biotech engineer worth anything will keep up with nanotech developments, as they have huge implications on medicine as a whole (e.g., highly-targeted drug delivery). I was asking what he meant, because his wording could have been interpreted as just about anything.
 
I have been wondering how your speedometer works on a conventional car and how accurate they are generally?, I know its hard to give figures on sure a general question but I have been rather curious. I am also curious would things like changing the gearing of your car affect your speedometer. Also a person I know in college has put some massive wheels on his car and whilst having low profile tyres it has increased the rolling radius of the wheels quite a bit, what affect will this have on his car, will it have the same effect as increasing the length of the gears, and will this throw his speedo out?
 
My uncle runs his own crash investigation team and there was a crash involving a Ferrari where the driver had put on tyres that the car wasn't designed for. It made the speedometer ineffective and probably got him off of a penalty.

I can't exactly remember the details of it, but it was along those lines.
 
Your speedo will tend to over-read by about 10%. But maybe greater at speeds of 20mph or less.

I don't think gearing would change the accuracy of the speedo, though increasing the radius will probably cause the car to under-read more (larger cirumference, fewer revolutions).
 
I will come back with a basic and general questions when I look into it more.
 
In older cars the speedometer was driven by a cable that came out of the transmission. The cable rotated in its housing, like a flexible drive shaft, and spun a magnetic assembly in the actual meter. The faster it spun, the higher the meter would read. If the car had a factory cruise control the speedometer cable went to that unit first (since it was under the hood), then another cable went to the instrument panel.

These days the transmission is still the source of the signal, but it drives an electronic sensor, basically a little generator, that increases voltage with vehicle speed. The reading is fed to the ECU, and the ECU in turn feeds it to the speedometer.

Speedomoters generally read just a little bit high because it's actually illegal for them to read low from the factory. Odometers, on the other hand, are pretty accurate.

Changing tire size or final drive ratio will affect the speedometer. Shorter gearing will make it read high, taller gearing will make it read low. A larger diameter tire will make the speedometer read low, and a smaller tire size will make it read high. Those changes also affect the odometer; shorter gearing or smaller tires will make the odometer read more miles than actually travelled.
 
It's amazing how often people seem to think that the speed of a car is measured by a vague tracking of the relative motion between the car and ground (I'm not talking about Stevisiov.). Most racing games do this, too.

Then a game comes along that gets it right, with burnouts affecting the speedometer, and people ask "why does it say 60mph when I'm barely moving?"
 
The gearing itself, by the way, won't affect the reading of the speedometer, since it's being taken off the final drive... a change of the final drive ratio will mess it up, though.

My speedometer reads perfectly. I've clocked it against a GPS performance box. But that might be because I've got tires that are about 2% taller than stock.

Disconnecting the speed sensor from the transmission makes the speedometer and odometer stop. Nasty, stinking, rotten car dealership trick to keep miles on test-drive units low. :D

A year or so back I heard about testing where they would inject sensors into athletes during practices and games on hot days in order to monitor body temperature and prevent heat related injuries, but I do not know if it was considered NanoMedicine or just tiny sensors. They would supposedly break down and be naturally removed as waste in 24 hours. If I can find a link I will pass it on.

Stevisiov.

My speedometer is off by between 3mph and 5mph over, according to police speed signs.

I knew some guys in the 90's who put those horrible small tires on their cars and when I commented on the affect on their speedometer one of them said the custom shop he used actually recalibrated his speedometer for him. Don't take that as fact though.

Probably a medical expansion on thermo-chromic smart technology. Which I don't believe is nano-tech.
 
Well this is rather more of an opinion than a question.....

How long does it take for a normal person to learn Japanese? (including learning how to read and write) I really do want to learn, but I have no idea where to start. Only know one or two phrases like that, but nothing else....... just wonder how hard could it be to learn a foreign language. :nervous:

If you're serious, research & buy a language tool like Rosetta Stone, or find a class. RS isn't cheap by any means, but it's been called amazingly quick & effective.

Well, wouldn't be stuck in the place of origin be better. Like students of a Spanish class could learn better in some parts of South America or living with certain families that speak the language but understand English.
To learn Japanese, is pretty from what I have heard of. Probably the thing that stuck with me was the ending titles like -sensei, - dono, -san,-chan, - kun. Otherwise, try to learn from what you got. Some fans just get dictionaries and look up the words.

I think it varies from person to person. A part of it is your determination, but I really believe that there is more to it than that.

I took four years of Spanish and can barely translate a few words to English. I took two years of German and could probably stumble through a conversation.

In looking at other languages I have found that romantic languages, like Spanish, French, and Italian do not stick well in my mind, but the Germanic languages come to me much more naturally. I completely gave up on East Asian and Middle Eastern languages because their alphabets are so far from even looking similar to English that I just feel overwhelmed.

I have also found that the languages I am able to pick up on are also the ones that I have the least trouble pronouncing. I am almost positive I have some kind of mental barrier that holds me back.

However, with you living in Malaysia I am going to assume you can speak Malay (official language?) and I don't know how large of a difference there is between that and Japanese, but I have to assume it would be easier for you than it would be for me.

Well it does seem quite good, but paying 200+$ (about RM709+) just seems a bit too much for me.... :guilty: Would be good if I really wanted to know more about the Japanese language. 👍

Well I get your point, but for me to move to Japan without knowing proper words is going to be tough. I mean I do get a few words from reading anime subtitles but lets face it, you will not learn anything like that. :p

Yeah, much easier for me. :) Weird as it seems, I do understand English a little better than Malay.......... :irked: But at least its probably easier to learn Japanese than to learn Mandarin or Cantonese.

Is there something abnormal about being Japanese?
Click to expand...
Huh? Well what is wrong for me to learn Japanese? I mean I do want to work and live in Japan, I watch a lot of Japanese anime, I do play a lot of Japanese video games (which I could barely understand or read) and learning Japanese has probably more benefits........

That's how I've learned English actually. Except it was movies and series instead of animes.
 
I too will be learning Japanese as of next year, although my first choice was German, my parents made me take Japanese. I've learned Italian for around 7 years when I was younger, and can't remember anything. I've learned French for 2 years now, and can't remember a thing. I've never had an incentive to learn those 2 languages, but I do with German and Japanese. I think that makes a difference, since Muzzy you're wanting to learn it'll be easier.
 
I'm going to learn Japanese as well. It seems that I have a natural flair for languages, despite not being able to stick to one. But, I plan on going to Japan for high school, as America's aren't as good. My local library used to have all languages on Rosetta Stone, for free, but it got stopped a few months ago.
 
Well apply to what you know. My friend was a anime fan for a good years, applied everything, he would sound off the same type of dialect of Japanese to various sentences and bam, he got it. Though most of the lines came from Cowboy Bebop. Just don't over do it....

I think I could do that as well. :p But be careful on which word you use when you talk with someone. I learn that saying "watashi" is for girls and saying "ohayou" or "konnichi wa" more than once to the same person would be weird.......

I don't know, I guess you have to learn all of these if you want to be good in Japanese. :p
 
How do we know what stars contain/produce what metals?

The question may not be worded right, but I'm hoping you get what I mean!
