A look at downtown Akron.
NBA star of the world champions Cleveland Cavaliers basketball team was born and raised in Akron.
In the downtown area of Akron, an area was developed to bring people into the city for free concerts and outdoor activities including ethnic festivals.

The term rock and roll began in Cleveland
Years ago, this river caught on fire because of the pollution in it. The city since has cleaned it up and made the area a tourist attraction with many stores and entertainment revenues.

This is the capital city of the state of Ohio.
One of the largest universities in the United States.
The stadium holds over 105,000 people for sporting and other events. The Ohio State football program is one of the best in the country.

From NBC News China -----------------------------------------------------------------------------------------------------------------------------------------------------------------
BEIJING — They say true loves waits — and one man who went looking for it online seemingly took that to heart.Alexander Pieter Cirk was due to arrive back home in Holland Tuesday after reportedly spending 10 days at a Chinese airport in a failed bid to meet a woman he'd fallen for on a dating app.
Apparently frustrated by the time and distance separating the couple, the 41-year-old decided to demonstrate his affection by applying for a visa and flying around 5,000 miles to visit her.
Prior to his July 17 departure, Cirk reportedly sent the 26-year-old woman a picture of his flight details.But thousands of miles and hours later when he landed in the Chinese city of Changsha, there was no sign of his online love.
Convinced that she would eventually come for him, Cirk decided to stay at the terminal and patiently waited for her.
Photos of him lounging around and wandering through Changsha Huanghua International Airport soon began to circulate on Chinese social media. Local news reports followed.
After 10 days, authorities reportedly took a frail-looking Cirk to a local hospital for treatment.
A spokesman for the Dutch Ministry of Foreign Affairs told NBC News Tuesday that Cirk had been hospitalized from "Friday 5:30 p.m. until [Monday] evening."
The spokesman added: "We contacted him [Cirk] and his doctor when he was in the hospital and of course we've asked if he needed our assistance but he declined the offer."Chinese and Dutch officials declined to discuss what Cirk was treated for.
Chinese state broadcaster CCTV reported that a local TV channel eventually tracked down the woman. She expressed surprise that her online boyfriend had been waiting for her to show up. She confessed that she thought Cirk was joking about the trip.
Zhang also claimed that she was scheduled to have plastic surgery and therefore hadn't been able to respond to Cirk's messages when he arrived in China.The woman reportedly added that she hoped to maintain her long-distance relationship with Cirk.

E = mc2. It's the world's most famous equation, but what does it really mean? "Energy equals mass times the speed of light squared." On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing. Under the right conditions, energy can become mass, and vice versa. We humans don't see them that way—how can a beam of light and a walnut, say, be different forms of the same thing?—but Nature does.
So why would you have to multiply the mass of that walnut by the speed of light to determine how much energy is bound up inside it? The reason is that whenever you convert part of a walnut or any other piece of matter to pure energy, the resulting energy is by definition moving at the speed of light. Pure energy is electromagnetic radiation—whether light or X-rays or whatever—and electromagnetic radiation travels at a constant speed of 300,000 km/sec (186,000 miles/sec).
Why, then, do you have to square the speed of light? It has to do with the nature of energy. When something is moving four times as fast as something else, it doesn't have four times the energy but rather 16 times the energy—in other words, that figure is squared. So the speed of light squared is the conversion factor that decides just how much energy lies within a walnut or any other chunk of matter. And because the speed of light squared is a huge number—90,000,000,000 (km/sec)2—the amount of energy bound up into even the smallest mass is truly mind-boggling.
Here's an example. If you could turn every one of the atoms in a paper clip into pure energy—leaving no mass whatsoever—the paper clip would yield 18 kilotons of TNT. That's roughly the size of the bomb that destroyed Hiroshima in 1945. On Earth, however, there is no practical way to convert a paper clip or any other object entirely to energy. It would require temperatures and pressures greater than those at the core of our sun.
