Problem: On the first day of school, Jack found a little old lady with a warm smile."Hi, handsome. My name is Rose. I'm 87 years old."she said. "Why are you in university at such a YOUNG age?" Jack asked. "I'm here to meet a rich husband, get married, have a couple of kids, and then retired and travel." she answered. Jack knew she's joking but he was surprised what encouraged her to be here at her age. "I always dreamed of having a university education and now I'm getting one!" she told me. We became friends. Every day they would talk after class. Jack always enjoyed listening to this "time machine" as she shared her wisdom and experience with him. And Rose easily made friends wherever she went. At the end of the term, Rose was invited to make a little speech. She said, "We don't stop playing because we're old. We grow old because we stop playing. Being happy and achieving success may keep you staying young. If you have a dream, hold on. When you lose your dreams, you die." "Anybody can grow older. _ doesn't take any talent or ability. The idea is to grow up by always finding the chance in change..."

Problem: Gamma rays (also called gamma radiation), denoted by the lower-case Greek letter gamma ( or formula_1 ), are penetrating electromagnetic radiation of a kind arising from the radioactive decay of atomic nuclei. It consists of photons in the highest observed range of photon energy. Paul Villard, a French chemist and physicist, discovered gamma radiation in 1900 while studying radiation emitted by radium. In 1903, Ernest Rutherford named this radiation "gamma rays". Rutherford had previously discovered two other types of radioactive decay, which he named alpha and beta rays.

Gamma rays are able to ionize atoms (ionizing radiation), and are thus biologically hazardous. The decay of an atomic nucleus from a high energy state to a lower energy state, a process called "gamma decay", produces gamma radiation.

Natural sources of gamma rays on Earth are observed in the gamma decay of radionuclides and secondary radiation from atmospheric interactions with cosmic ray particles. There are rare terrestrial natural sources, such as lightning strikes and terrestrial gamma-ray flashes, that produce gamma rays not of a nuclear origin. Additionally, gamma rays are produced by a number of astronomical processes in which very high-energy electrons are produced, that in turn cause secondary gamma rays via bremsstrahlung, inverse Compton scattering, and synchrotron radiation. However, a large fraction of such astronomical gamma rays are screened by Earth's atmosphere and can only be detected by spacecraft. Gamma rays are produced by nuclear fusion in stars including the Sun (such as the CNO cycle), but are absorbed or inelastically scattered by the stellar material, reducing their energy, before escaping and are not observable from Earth as gamma rays.

Problem: Once upon a time there were a zebra and a monkey in a zoo. The zebra and the monkey had many napkins. What did the zebra and the monkey do with all the napkins? They didn't know. They ate the napkins. The zebra felt good. The monkey got a stomach ache. Why did the monkey get a stomach ache? The napkins were make out of straw. Straw is good for zebras. Straw is not good for monkeys. The monkey did not like eating the napkins. The zoo worker came and gave the monkey a pill. The pill made the monkey feel better. Now the monkey does not eat napkins. The monkey eats bananas instead of napkins. Now the monkey is always happy and feels good. The zebra does not like to eat bananas. The zebra eats all the napkins and feels good. The zebra and the monkey are both very happy.

Problem: Mary and Peter were having a picnic with some friends near a river when Mary shouted,"Look!That's a spaceship up there and it's going to land here." Frightened by the strange spaceship,all the young people got into their cars and drove away as quickly as possible except Peter and Mary. They were more curious than frightened. They watched the spaceship land and saw a door open,but nobody came out,so they went to look into it. In the center of the floor,there was a lot of food. Peter followed Mary into the spaceship and did not hear the door close behind him. The temperature fell in no time and very soon the two young people didn't know anything. When they came to themselves,they were surprised to see that the spaceship disappeared, their car was near them. "What happened?"asked Mary. Peter scratched his head,saying slowly,"Don't ask me. Perhaps we had a problem. Come on. It's time to go home." After driving about fifty meters,they found a thick wall made of something like glass stood in their way. On the other side of the wall,a few strange aliens were looking through the wall and reading a notice,it said,"New comers at the zoo: a pair of earth villagers with their _ ."
