How to Be Happy?

 So happiness - isn't that the thing that all of us strive to find and keep? Nobody is happy all of the time, but some people are definitely more fulfilled than others. Studies on what makes people happy reveal that it doesn't have much to do with material goods or high achievement; it seems to whittle down to your outlook on life, and the quality of your relationships with the people around you.

Automotive Illustrations by Kevin Hulsey: Toyota Supra

Retrieved from www.khulsey.com
 Toyota Supra is a sports car or grand tourer that was produced by Toyota Motor Company from 1979 to 2002. The styling of the Toyota Supra was derived from the Toyota Celica, but it was both longer and wider. Starting in mid-1986, the Supra (in its third generation, Mark III) became its own model and was no longer based on the Celica. In turn, Toyota also stopped using the prefix Celica and began just calling the car SupraDue to the similarity and past of the Celica's name, it is frequently mistaken for the Toyota Supra, and vice versa.

Statistics - Hypergeometric Distribution

 Hypergeometric distribution is a discrete probability distribution that describes the number of successes in a sequence of n draws from a finite population without replacement, just as the binomial distribution describes the number of successes for draws with replacement.

Here's an example problem number 5.29 retrieved from Scientists and Engineers guide to probability & statistics eighth edition by Walpole, Myers and company.

 Ferrari used its 2 L (1995 cc/121 in3V12 engine in a number of models, all called 166 for the displacement of a single cylinder. Most early 166es were sports cars built for racing, though a later line of GT cars launched the company's street model line.
The following models used the 166 name:

History of Solar Panel

history of solar power

What is a Solar Panel?

A Solar Panel is a device consisting of flat-shaped collection of solar cells or thermal collectors that is connected to each other and is intended to convert solar energy into heat or electric power.

Solar Panel as the name denotes is a gadget intended to gather and capture the energy from the sun. The solar cells are also referred to as the photovoltaic cells. The term photovoltaic means light and electricity.

History of Solar Panel: Its Invention

Since the early times, man has seen the great potential in the sun as an enormous source of power and energy. And in the course of history, he has devised means to tap into this great energy source in the heavens. Indeed, the sun is an ideal power giver: the solar energy is ever-flowing and inexhaustible and free from creating pollution.

In ancient Europe, the Romans and Greeks realized the vastness and availability of the power from the sun, and they used this power through the designs in their houses. They also used solar energy to compliment the available means of energy then, which was twigs, logs and lumber for burning.

During the period of the industrial revolution, scientists and engineers searched to tap on the solar power as an effective alternative to the coal-dependent steam engine.

Auguste Mouchout is the inventor of the first solar motor – in the early 1960’s he was able to invent a steam engine that will run on solar energy. But because coal was becoming a cheap source of energy, his invention as an important landmark in the Industrial Revolution history came and went unnoticed.

John Ericsson in the United States is one of the pioneers in the development of solar power. He is the inventor of the parabolic trough collector, design still in use until today.

In 1921, Albert Einstein’s research on the photoelectric effect garnered for him the Nobel Price in Physics. The creation of energy from solar cells is the concept of the photoelectric effect.

In 1941, Russell Ohl is awarded the patent for the modern solar cell.

Kinematics - Spur Gears

 Spur gears or straight-cut gears are the simplest type of gear. Sometimes, many spur gears are used at once to create very large gear reductions.They consist of a cylinder or disk, and with the teeth projecting radially, and although they are not straight-sided in form, the edge of each tooth thus is straight and aligned parallel to the axis of rotation. These gears can be meshed together correctly only if they are fitted to parallel axles. 

Retrieved from Wikipedia.org
Two meshing gears transmitting rotational motion. Note that the smaller gear is rotating faster. Although the larger gear is rotating less quickly, its torque is proportionally greater.
