Theory of Relativity in Space
Albert Einstein's theory of special relativity explains how space and time are linked, but it doesn't include acceleration. By including acceleration, Einstein later developed the theory of general relativity, which explains how massive objects in the cosmos distort the fabric of space-time. The theory explains how this distortion is felt as the force of gravity, as it predicts how much the mass of an object curves space-time. Scientists test relativity by observing objects in space and seeing if their behaviors match up with Einstein's explanations of space-time and gravity, for instance by observing how light bends around massive objects as it travels towards Earth.

Challenge yourself with new goals
Every year, my climbing has progressed to new levels and I challenge myself with new goals.
You're out there taking big, dangerous falls. You're going up there and causing a ruckus on the wall, defying gravity, defying fear. It’s a new form of rebelliousness.
Obama’s Speech at the U.N - America & Iran
I don’t believe this difficult history can be overcome overnight – the suspicion runs too deep. But I do believe that if we can resolve the issue of Iran’s nuclear program, that can serve as a major step down a long road towards a different relationship – one based on mutual interests and mutual respect.
We are not seeking regime change, and we respect the right of the Iranian people to access peaceful nuclear energy. Instead, we insist that the Iranian government meet its responsibilities under the Nuclear Non-Proliferation Treaty and UN Security Council resolutions.
Meanwhile, the Supreme Leader has issued a fatwa against the development of nuclear weapons, and President Rouhani has just recently reiterated that the Islamic Republic will never develop a nuclear weapon.
We are encouraged that President Rouhani received from the Iranian people a mandate to pursue a more moderate course. Given President Rouhani’s stated commitment to reach an agreement, I am directing John Kerry to pursue this effort with the Iranian government, in close coordination with the European Union, the United Kingdom, France, Germany, Russia and China. The roadblocks may prove to be too great, but I firmly believe the diplomatic path must be tested. For while the status quo will only deepen Iran’s isolation, Iran’s genuine commitment to go down a different path will be good for the region and the world, and will help the Iranian people meet their extraordinary potential – in commerce and culture; in science and education.
The artificial lake at Chitgar Park - Tehran
The artificial lake at Chitgar Park is one of the big projects in Tehran which has been designed on the basis of expert aptitude and studies of domestic specialists. Now, after its opening, it provides a new opportunity in the area of tourism in Tehran.The project for construction of an artificial lake in Tehran was raised as an urban law in the Comprehensive Plan in 1970 and was followed in 1976 and 1988 but was later abandoned. Finally in 2007 urban managers decided to implement the project after 40 years in the same geographical location which is now District 22 of Tehran Municipality. After completing the study phase, ground was broken for the project in the month of February 2012. Now after 15 months the first phase of the project has been launched in an area of 123 hectare and its massive recreational complex has been completed. Tehran Mayor Mohammad Bagher Ghalibaf opened the Persian Gulf Martyrs Lake.

Many critics believe that Argo is an attempt to describe Iranians as "overemotional, irrational, insane, and diabolical while at the same, the CIA agents are represented as heroically patriotic."

Chabahar Free Trade Zone Commercial
Chah Bahar is a city in and capital of Chah Bahar County, Sistan and Baluchestan Province, Iran. Chah Bahar is a free port (Free Trade Zone) on the coast of the Gulf of Oman. Chabahar is situated on the Makran Coast and is officially designated as a Free Trade and Industrial Zone by Iran's government. Due to its free trade zone status, the city has increased in significance in international trade.
Chabahar is Iran's closest and best access point to the Indian Ocean. For this reason, Chabahar is the focal point of Iran for development of the east of the country through expansion and enhancement of transit routes among countries situated in the northern part of the Indian Ocean and Central Asia.
It has the same latitude as Miami in Florida, USA, and weather conditions are very similar to those in Miami.

UWB RADAR
Ultra Wideband (UWB) radar systems transmit signals across a much wider frequency than conventional radar systems and are usually very difficult to detect. The transmitted signal is significant for its very light power spectrum, which is lower than the allowed unintentional radiated emissions for electronics. The most common technique for generating a UWB signal is to transmit pulses with very short durations (less than 1 nanosecond).
The spectrum of a very narrow-width pulse has a very large frequency spectrum approaching that of white noise as the pulse becomes narrower and narrower. These very short pulses need a wider receiver bandwith as conventional radar systems.
The amount of spectrum occupied by a signal transmitted by a UWB-radar (i.e. the bandwidth of the UWB signal) is at least 25% of the center frequency. Thus, a UWB signal centered at 2 GHz would have a minimum bandwidth of 500 MHz and the minimum bandwidth of a UWB signal centered at 4 GHz would be 1 GHz. Often the absolute bandwidth is bigger than 1 GHz.

روش تهیه لیموناد تابستانی کلاسیک
نوشیدنی خنک لیموناد را برای روزهای گرم تابستان انتخاب کنید.
دستور تهیه:
• ابتدا لیموها را پوست کنده سپس به آنها را به شکل حلقههای نازک برش دهید.
• درون کاسهای جداگانه، برشهای لیمو را قرار داده و روی آنها، شکر بپاشید و آنها را به مدت یک ساعت در دمای اتاق قرار دهید.
• درون یک قابلمه دربدار، آب را جوش آورده و آن را فورا روی حلقههای لیمو بریزید و 20 دقیقه صبر کنید تا خنک شوند سپس آن را صاف کرده و حلقههای لیمو را بیرون آورید.
• حلقههای لیمو را درون کاسهای دیگر فشار داده و آب آن را خارج کنید. آب لیمو حاصله را به مخلوط شکر اضافه کرده و آن را هم بزنید بگذارید خنک شود، سپس آن را میل کنید.

The Great Radio Spectrum Famine
Mobile broadband is consuming the available radio spectrum. Serving up more won't be easy Not even sci-fi writers foresaw what we'd be doing with our phones once technology put color screens and a lot of computing power in our pockets. Now we know: We use them to stream YouTube and Facebook videos; we watch TV shows; we download and store songs and movies; we take pictures of everything going on around us; we read (and some of us even write) novels; we play video games; we surf the Web. Sometimes we even talk to each other. These days you can unleash a gusher of bits over the air that would have choked even a wired connection to the Internet not so long ago.These transmissions consume radio bandwidth—lots of it. And they will take increasing amounts of this precious commodity as the iPad and its Androidgenous kin proliferate. People are already feeling the pinch. read more
