Where can I find a tracking device detector? I need an electronic device that will detect for me if someone has hidden a tracking device in any of my things. Where can I find something like this? How does it work? How do the tracking devices work? Do they use UHF? Sattelite or the cell towers?

Thanks for the help.

My husband would like to take the PE exam for Mechanical in April of 08, here in California. He was told by a co-worker that unless you take a preparation course, the pass rate is only 25%. We would love for him to take the course but it's almost $1000 without the latest and greatest editions of the book. He bought the latest edition in June of last yr and that is the edition he has been studying out of.

25% doesnt seem like really good odds to me. I wondered if it was a marketing scheme for the company that was giving the course or if it really is that low. My husband would like to study on his own and also, the course is INCREDIBLY expensive but if it's the only way people can pass the exam successfully is it worth taking? He is a Cal Poly graduate in Mechanical Engineering and has worked in the industry for 3 yrs now. He is also doing a lot of project management and has been promoted a couple of times in his company. I think he can do it, but am I right?

How can he prepare?

This is something that I have been researching for the last few days after a strange thought ran across my mind.

Have we as humans really landed on the moon? If so, why has there not been an anniversary or second exploration of the desolate planet?

It is very weird to me that with so much technology such as GPS tracking, sonar, solar energy and a list of other magnificent technologies, that now in 2007 we are not building things on the moon, landing on other planets, and having space launches for folks across the globe to view space and other planets.

It is also strange to me how we can build space suites to withstand the pressure of outer space, but we can not develop a machine or humanoid suit to withstand the pressure of our deep blue seas.

Hopefully you guys can shine a little bit of light on the situation. What do you think?

So you have a lot of people on here that have PhDs and are even considered the top in their field. I know a lot of you ask homework questions and could care less, but do you realize that when choose as best, answers that; clearly don't understand what you are asking, or clearly don't understand the subject matter, or are merely repeating what someone more qualified has already said
that you drive away the more qualified people on here and lower the overall quality of answers you get?

Do you care?

I've noticed some of our best answerers have just slowly migrated away as they lose patience. I don't think they care if they get best answer, but when there are no other answers that are even good and they don't get chosen, why bother to keep answering?

I just turned 14 in june and i am a male asian. I am currently 5'6. When i was 10-11 i barely grew (i was 5'0) then when i was 12 i was 5'3 and when i turned 13 i was 5'6. I went to the doc. and he told me i had osgood schlatter disease and he told me my growth plates were still open.

My dad is 5'7 and my mom is 5'5 however the rest of my family is 5'10 and above. My mom and dads size are like that cuz they did not have the enough nutrients when they were young, the younger bros and sis were taller cuz my parents had to work so my uncles and aunts are way taller.

So these are my questions:
1. Did i have a growth spurt or am i gonna have between my 14-15?

2. Did i reach my adult height?

3. How much do u think ill grow?

4. What do u think will b my adult height?

5. Will i continue to grow?

1st of all, im just a 15 year old highskul student kid and im very curious about UFO's and stuffs...Before, I dont beliv about UFOs but due 2 my curiosity, i began 2 search on the net and I now beliv dat theres something out there. when u talk about ufo, people will laugh behind ur back and there goes ur carrer.

The Universe is built up of billions of stars and galaxy. Life and civilization is possible out there that is thousands of years ahead of us and also in termss of their technology..antigravity and etc.. Maybe some of u doesnt know that NASA, US military and other govt' are keeping the secrets and hiding them for decades & decades.

I recommend ya'll to see the video in youtube or search in wikipedia about "UFO DISCLOSURE PROJECT"

recently, i found some pictures of the moon and i noticed some were airbrushed by nasa. i looked like alien bases. then i visited youtube and found videos..so yea. NASA is hiding dirty secrets.

I mean summer, winter etc
I know some people will say Football season, that would be so funny in fact I would probably split my sides laughing at such witty responses but seriously I would love to know which season you love best, I really love winter, those crisp cold mornings, icy air, fresh snow, when I see such a morning I am in heaven.
