The Importance of Being Social with Your Pet Parakeet

Parakeets are extremely social birds. In the wild, they live in huge flocks, sometimes numbering up to thousands of birds. Even in pet store cages, these quirky little birds establish pecking orders, form bonds, and play follow the leader. They even socialize with birds in other cages or of different variety.

This is why before you decide to raise a pet bird, you need to know how much time you're able to spend with it. The ideal amount of birdie playtime per day is 30-60 minutes. At first, you may be overwhelmed by this, but you may find that like many new bird owners, one you start playing with your pet parakeet, you can't stop. After all, parakeets are intelligent, playful, energetic, and curious birds. Something fun you could do with you parakeet is to let him explore the area, tweet along to a favorite song, or reward him with pats and treats for learning a trick. Many parakeets also enjoy showing off their acrobatics, like doing backflips on their perches or climbing things. If you really put in the time and effort, you may even be able to teach him how to talk!

Research by avian specialists and animal behavior experts have proven that birds, especially parrots, can get depression. This condition may be caused by grief or loneliness. Symptoms of avian depression are similar to human depression. They may include loss of appetite, lack of interest, and neglect of personal grooming, and an overall droopy appearance.

Make sure you prevent this from happening by giving your parakeet lots of love and attention. If you find that you are not able to spend enough time with your parakeet to keep him happy, a good thing to consider is to get him a little friend of the feathered variety!

ENIAC~ Draft for translation into Chinese

Covering 1800 square feet of floor space and weighing over 30 tons, the ENIAC, Electronic Numerical Intergrator and Computer, made history in 1946 as the world's general purpose electronic computer.1 At the time, it was frequently heralded in the press as a "Giant Brain"2 When the ENIAC first came out, it was over a thousand times faster than any calculating machine to date and could solve 5,000 additions, 357 multiplications or 38 divisions within a second.3 It could also predict weather and do a variety of scientific tasks.4 What made the ENIAC special was that it was the first truly universal computing device, unlike any other machine before.5 Some of the ENIAC's competitors, such as the Z3 and the ABC were far slower and were capable of solving only small problems.6

However, what is known as ENIAC's biggest accomplishment was how it sparked the imaginations of scientists and industrialists worldwide.7 It inspired many to attempt to create even more powerful devices.8 Many scientists and engineers raced to create faster, smaller, lighter, cheaper, and more advanced hardware.9 Within a few years, computers were popping up everywhere- universities, government agencies, banks and insurance companies.10

Though it wasn't extremely powerful, the ENIAC was a huge advance leap from any computing device of its time.11 More importantly, it revolutionized computers and greatly influenced the development of later computers.12

The Science Behind a Bouncing Ball

When a ball is held in the air, it has potential energy. Potential energy is energy that is stored or "hidden in some way. When the ball is dropped, the potential energy is converted to kinetic energy. As the ball moves through the air, the air gives resistance. Resistance makes some of the kinetic energy inside the ball convert into heat, therefore slowing down the ball. When a ball bounces, it means that very little of the kinetic energy inside was lost. Then the ball would hit the ground, deform for a moment, and bounce up as it snaps back into shape. This ties into Newton's Third Law of Motion- every action has an equal and opposite force. This is because when a ball falls down, it has energy and pushes against the floor when it hits. The floor pushes back equally as hard and creates the deformation, snap, and bounce. However, sometimes all the energy in a falling object is lost to sound, heat, light, or something else. Then, the object will not have any force when it hits the ground and therefore will not bounce. The more energy is lost during a drop, the less an object will bounce. Finally, comes the bounce. The first bounce will be the highest, because the least amount energy has been lost. After the ball reaches its highest bounce point, it will repeat the bounce process (resistance, energy loss, deformation, snap, etc.) until it eventually loses all of its energy and stops.
