Let's Kill Some Time!

Many scientists believe that time travel is possible by using wormholes. According to the theory of relativity a person that moves fast enough to open a wormhole will basicly open a portal to a different period of time and the wormhole will be it's gate. Let's say that two people that are in the same age are holding hands and one of them is going into a wormhole. The person that went into the wormhole will go out after a period of time while the other person will grow much older than the person that came out of the wormhole. because when the person went into the wormhole time moved slowly while for the person that waits for the person that went into the wormhole time moved normally.


Atomic clock is basicly the most exact clock that has been ever made. It is based on atomic energy levels that create a repitive signal that almost has no changes in it and by counting the changes it is possible to know what time is it.
.
Atomic clocks are used to show what time is it in some of the communication companies such as some of the television companies and the cellphone companies. - You need to specify more about this. This text is not enough to understand the device.

Writing Assignemt No.3: describing a place

I would like to tell you about an amazing city in Spain called Barcelona. The spoken language in Barcelona is spanish and the streets look the same except for the center of the city that is basicly a big traffic circle. Near the center of the city there's a beautiful fountain that lights the streets with the colors of a rainbow.

I recommand that if you ever visit in Barcelona also go to the Dali museum and see Salvador Dali's amazing arts. Another magnificent place that I think that you should visit if you're there is a place called Empuriabrava. Empuriabrava is located by the shore and it's main source of income is in giving tourists tours in the place with their boats. If you get to Empuriabrava notice the unique style of constructing.

And to conclude Barcelona is a great place to visit in and don't forget the most important thing:
choose a hotel carefuly because the way the spanish people give their hotels stars is not the same way the israelis do which may cause a few problems if you don't do as a I recomend.
