The Lightbulb

In from 1750 of all inventions that were created during the 1900 year, light bulb might be one of the most effective in the daily life of people. That invention was invented by Thomas Alva Edison, an American inventor and businessman who founded it in 1879. The design of his bulb is the carbonized filament inside the glass bulb with the screw base. When current passes through it, it becomes bright, has high resistance, and lasts much longer than the previous source.

Many people think that Thomas Edison is not the inventor of a light bulb. Others have created an initial bulb, but Edison has completed a durable incandescent bulb. Before he found a carbonized bamboo wire, he tried various wires. Why is he so successful? Because he showed the secret power of the inventor. The inventor's secret is experimentation. I recently exchanged email with Brian Gardner. He is the chief product officer of Copyblogger Media, a competent designer and author. I like a simple approach to his website design. In particular, I asked if it is a bad idea to put the e-mail registration form at the bottom of the site's website. Normally bloggers place their email registration near the top of the page to get the maximum exposure. However, some people think that if you like your content, you just register. Among Brian 's reply, he suggested that I try the bottom of the page. In other words, experiment

Learning is not a light bulb. The light bulb is very simple. They illuminate the dark. As a technological innovation, light bulbs are changing the world, but what they do is not complicated by experience. In contrast, learning is a complex human activity that is influenced both outside and inside the university. Then compare Edison and Dewey and talk about the way you learn. For Edison, learning involves adults who teach their children knowledge in an "attractive and fun way". For Dewey, learning includes the questions that children ask, because it is important to them, they will be able to "things actually." For Edison, the textbook of the problem, they are boring, of life is that it is not possible to capture the "more accurate, more vivid" reality. Dewey would say that the textbook hindered "active cooperation in the construction of students" in her research. As Dewe wrote in his slim experience and education later,

Imagine connecting the bulb to the digital compass. First of all, we need to choose the destination and purpose. I will start walking now. If you go to the destination, the bulb will remain glowing. But as you depart from the way, the energy supplied to the bulb will slowly dissipate. The light bulb gets dark. This is how happiness works. In order for your happy light bulb to light, you must keep moving toward your goal. When approaching the destination you may find it useful to remember another goal. When happening without arrival, the bulb of happiness starts to disappear. In addition to myth and philosophy, modern psychology and neuroscience also point out this deep truth. To pursue meaningful goals, happiness shines most
