RF: the first day I live in school
Today is my first day in college; I am very excited and open my mouth with a smile, because it is the school I dreamed of for many years.
When I first come into here, I felt everything is mine, every people is looking at me. Then soon I arrive in my bedroom, there are three people there, I think they are my classmates. I say hello to them and they say to me too. Then one of them come to me and say rf cp, I am surprise and staring at him, because I do not understand him and I do not know what is it that he said to me just now. After I finished tidying up all my things and go to ask him what he said to me just now. He says he said the game RF and wants to play the game with me. I tell him I never heard this game and even can not play. He says he will tell me how to play if I play the game with him. I agree with him.
Then he takes me to a place which can play the game. He gives me some rf gold, he says it is used to play the game. Each of us find a computer and sit down. He then tells me how to enter in the game and how to buy some weapons which will use some rf online gold and how to control the whole screen on the computer.
At first I can not handle it fluently, but with the help of him, I soon can play with ripe. When he sees my skill can play the game with him, he let me to play with him for a while. But I tell him I have lost all my game gold all just now, he has no idea and give me another rf money for the next game. Then we enter in the game together and play just as the partner. I soon find that the game is very funny and can make us excited. We still played for two hours. After that we come to a restaurant to have our supper and we still aftertaste the scene we played. We all have a good day on the game.
The next days in school I often play the game with him and we win back much more cheap rf gold than before.
I think it is a good game and I love it.
Here's the science of black holes, from supermassive monsters to ones the size of ping-pong balls.
- There's more than one way to make a black hole, says NASA's Michelle Thaller. They're not always formed from dead stars. For example, there are teeny tiny black holes all around us, the result of high-energy cosmic rays slamming into our atmosphere with enough force to cram matter together so densely that no light can escape.
- CERN is trying to create artificial black holes right now, but don't worry, it's not dangerous. Scientists there are attempting to smash two particles together with such intensity that it creates a black hole that would live for just a millionth of a second.
- Thaller uses a brilliant analogy involving a rubber sheet, a marble, and an elephant to explain why different black holes have varying densities. Watch and learn!
- Bonus fact: If the Earth became a black hole, it would be crushed to the size of a ping-pong ball.
From time-traveling billiard balls to information-destroying black holes, the world's got plenty of puzzles that are hard to wrap your head around.
- While it's one of the best on Earth, the human brain has a lot of trouble accounting for certain problems.
- We've evolved to think of reality in a very specific way, but there are plenty of paradoxes out there to suggest that reality doesn't work quite the way we think it does.
- Considering these paradoxes is a great way to come to grips with how incomplete our understanding of the universe really is.
In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.
- The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
- Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
- Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.
