The Teddy Bear essays

The Teddy Bear essays There are many variations of the story explaining the origin of the teddy bear. Some believe it was completely a German creation. Others believe it was American. Some say it was a combination of the two. Still, others think it started in England. The first story is that of Margarete Steiff, a woman born in Giengen, Germany in 1847. When she was only two, she contracted polio and spent the rest of her life in a wheelchair (Margarete). That didn't stop her from being productive. She loved children and they visited her often (The). One day, she noticed a pattern in a magazine for a toy elephant. She started making a few elephants and gave them as gifts to friends and neighbors. Childrem loved it! Then, she started making other animals like a poodle, a bear, and a donkey (Margarete). Her nephew, Richard had been fascinated with bears. He had been watching a family of brown bears at Nills Animal show and sketching their antics for his aunt (Origin). He also helped her with designing her stuffed bears. In 1903, he brought some of her bears to the famous Leipzig fair (Margarete). This is where the story would end for one who believed the bear's origins were only in Germany. But, on the last day of the fair, a man named Hermann Berg, a buyer from a New York firm called Geo Borgfeldt went to the Steiff stand. He'd been complaining that there was nothing new at the fair. Then, he saw the bear and knew there'd be a market for it in the U.S. He placed an order for 3,000 bears (Margarete). That very year, Theodore Roosevelt, (known as "Teddy" to close friends), had gone to the backwoods of Mississippi hunting for bears. Several days passed and he and the rest of the expedition hadn't caught a bear. The guide then found a little bear cub in the brush and presented it to the President. He refused to kill it and ...

Examples of Radiation (and Whats Not Radiation)

Examples of Radiation (and What's Not Radiation) Radiation is the emission and propagation of energy. A substance does not need to be radioactive in order to emit radiation because radiation encompasses all forms of energy, not just those produced by radioactive decay. However, all radioactive materials do emit radiation. Key Takeaways: Radiation Examples Radiation is emitted whenever energy is propagated.A substance does not need to be radioactive to emit radiation.Not all isotopes of element emit radiation.Common examples of radiation include light, heat, and alpha particles. Radiation Examples Here are some examples of different types of radiation: ultraviolet light from the sunheat from a stove burnervisible light from a candlex-rays from an x-ray machinealpha particles emitted from the radioactive decay of uraniumsound waves from your stereomicrowaves from a microwave ovenelectromagnetic radiation from your cell phoneultraviolet light from a black lightbeta particle radiation from a sample of strontium-90gamma radiation from a supernovamicrowave radiation from your wifi routerradio wavesa laser beam As you can see, most of the examples on this list are examples from the electromagnetic spectrum, but the energy source doesnt need to be light or magnetism to qualify as radiation. Sound, after all, is a different form of energy. Alpha particles are moving, energetic helium nuclei (particles). Examples of Things That Are Not Radiation Its important to realize isotopes are not always radioactive. For example deuterium is an isotope of hydrogen that is not radioactive. A glass of heavy water at room temperature does not emit radiation. (A warm glass of heavy water emits radiation as heat.) A more technical example has to do with the definition of radiation. An energy source may be capable of emitting radiation, but if the energy doesnt propagate outward, its not radiating. Take, for example, a magnetic field. If you hook up a coil of wire to a battery and form an electromagnet, the magnetic field it generates (actually an electromagnetic field) is a form a radiation. However, the magnetic field surrounding the Earth is not typically considered radiation because its not detached or propagating outward off into space. Source Kwan-Hoong Ng (October 2003).
