We are going to discuss how all this technology regarding reverse telephone number lookups later. But for now, just understand that this can be an invaluable tool for just about anyone to use. Are you a landlord who wants to check on a potential tenant, or perhaps a tenant that has not been paying rent and ran off? Are you wondering where your blind date really lives? It is easy to do a reverse number lookup on these people and find out the truth. There are a lot of people who are still amazed that this actually works, it is very easy, just logon to your favorite number search website, enter the details, then get your information. You can enter the number in a standard search engine, but you most likely will not find what you are looking for.

The telephone search directories get their information from databases that are not accessible by the search engines. Anytime someone buys a magazine subscription or puts their number anywhere in a database, it can be found in these databases. The system can determine whether it is a cell phone number by the digits that are contained in the number. Cell phones typically use a range of prefixes that identity them as cell phones. Once a match is made with a person’s name, the system can determine if it is a landline or cell phone.

The databases that contain the numbers are constantly changing and being updated. Now that you know that they work and understand what is going on, you may feel more comfortable in using one. If you get a lot of harassing calls, do not put up with it. Do your homework, there is power in knowledge, make sure you get yours.

There is little celebration for a science fiction or fantasy writer. Many of the greats were little noticed in their lifetimes. Though this is certainly not the case with Clarke, Philip K. Dick, Robert Heinlein, or Isaac Asimov, there are a hundred writer for each of them that have never seen a Nebula Award or an Oscar. Literary or even cultural obscurity is one thing, but to fail to recognize a scientific breakthrough is shameful.

Though those in the know are aware Clarke was a great writer, they are usually not aware of the fact he pioneered the concept upon which modern global satellite communication is based. Having served in the Royal Air Force from 1941 through 1946 as a radar instructor and technician, Clarke first proposed the idea of a satellite-based communications system in 1945. He proposed geostationary satellites could be used as telecommunication relays in a paper entitled Extra-Terrestrial Relays, which was published in Wireless World in 1945.

It is hard to fathom the profound affect his simple idea has had on our daily lives, especially with regards to GPS tracking systems. It is easy to take the technology that makes cellphones and instant driving directions possible for granted. By triangulating a receiver on a phone or GPS device, satellites can pinpoint our location and lead us, as it were, to the Promised Land. A bit much to ask of a cellphone? Perhaps.

It is impressive that he envisioned the potential of the satellite well before the computer was little more than conjecture. He claimed the idea came from his experience with radar systems, wherein objects and their direction and trajectory can be accessed by the bounce effect of radar waves off metallic objects. GPS tracking systems and wireless telecommunications work on the same principle of deflected and directed waves, all triangulated by the sea of satellites orbiting the earth. A debt is owed to this bold visionary.
