Who invented the cell phone and when?
Martin Cooper invented the cell (mobile) phone. He was the first one to make a call and speak on his moble phone.
Mr Cooper, born December 26, 1928, wanted people to be able to carry their phones with them anywhere. While he was a project manager at Motorola in 1973, Cooper set up a base station in New York with the first working prototype of a cellular telephone, the Motorola Dyna-Tac. After some initial testing in Washington for the F.C.C., Mr. Cooper and Motorola took the phone technology to New York to show the public.

The idea of the cell phone began in the 1920's with police radios, but it wasn't until 1947 that the first one was made by Bell labs. In 1974 Dr. Martin Cooper is given credit for the cell phone that is most like the ones we have today. He was working for Motorola at the time. The phone was only for government use and in 1984 it was sold to the public for the first time. The early cell phones were large, heavy, and copied land line phones in style. They were carried in a zippered bag with the whole bottom as the battery.
The cell phone was first thought of in the 1920's when the use of police radios began. In 1947 Bell Labs made the first cell phone, but it took Dr. Cooper of Motorola to make a cell phone in 1974 for the government. The public use of cell phones began in 1984.

How much does it cost to recharge a cell phone battery?
Only running cost is the cost of electricity consumed to charge the battery through a charger. How many units of electricity is consumed will depend on the capacity of battery, efficiency of the charger (and so losses of energy in the charger in form of heat and radiation). You can estimate the power consumed by the voltage and wattage rating of the charger and how long it takes to charge the phone battery fully. - Neeraj Sharma

== == * Yes. If she is hiding something, then she is cheating on you in some form. She may not be sleeping with him, but it is still emotional cheating to be hiding. She is giving him her time and attention which belong to you. Get counseling if this marriage is worth saving. == == * Communication with your wife is the key. Considering you are married don't you think it wise to ask her about it. Unless you know for a fact this is her girlfriend's phone # then there is no reason to be suspicious (women talk a lot to each other.) My husband certainly doesn't know all my girlfriend's phone #'s. There is a possibility she may be cheating, but don't accuse her of anything, but ask her if she's unhappy in your marriage because you get a feeling she isn't being truthful to you. Get talking before you second-guess and get yourself into big trouble!
What are some good icebreakers for shy girls?
I'm assuming you're talking to a guy that you like. This is what I used to do: I'd just pretend that he was my guy cousin. I know it sounds stupid, but it really works! I just pretended I was talking to this cousin of mine, then suddenly I didn't feel that shy. After a little while I'd kind of remember that I wasn't talking to him, but it was fine because I wan't shy anymore! After a little while I didn't even have to use this little trick, but it really works.
If that doesn't work for you (it did for me, but hey, we're all different), I'd drag out some old things that work and have been repeated again and again. If you're in the same class or share teachers, talk about that, or mutual friends. If you don't know him that well, try asking him about his favourite football team, siblings etc. Don't let him do all the talking, but neither should you!
I'm not sure if that's exactly an icebreaker, but I hope it helps.

If it was a woman asking this question I'd tell her to be careful, but since you're a guy, you knew when you went into a chatroom you would probably meet someone there. Although not the safest way to meet people, I have heard of couples getting together and having a fairly successful relationship. The problem is, you haven't seen this person and have no way of knowing if they have a quirky personality, or what they look like or if they are married or cheating. You are going to have to decide whether you want to risk it or not. Meet in a public place NOT AT YOUR HOME and YOU SHOULD NEVER GIVE YOUR PHONE # OUT, EMAIL, ETC. until you know this person better. When you are talkingt to this girl don't "tell all" about yourself. Take it slow and easy and see how things go. Private information comes later in a relationship. I have to say that meeting the opposite sex can't beat the good old fashion way ... meeting at a party or public function or through friends. Good luck (be careful) Marcy
