Handbook of Physics

tellmaine.org – For a number of college and high school students, studying physics lessons that can be quite difficult and complicated to understand the different laws, theories, mathematical equations, and the like. Sometimes, students find lessons that are less by a teacher in wikipedia site online. To listen attentively to instructional lectures, and to pay attention to what the professors are trying to convey to help facilitate the internalization of knowledge held. One of the more important things students can do is learn to discipline focus on textbooks.

Learn from one book is not enough to be able to master the material well. So, it helps you buy the book Physics by Douglas C. Giancoli as your handbook. Look for the handbook that you understand the explanation is easy. No doubt that some physics books written in a style that is difficult to understand students. That’s why looking for a book that communicative and easy to understand is a must if you want good physics.

Learning to Create a Website Using PHP

Learning to Create a Website Using PHPLearning PHP can be done at the institute computer course or if you want a cheaper cost and faster, you can download the PHP tutorials and how it works on the internet.

Personal Home Page Tools (PHP) is a commonly used programming language for web development and can be incorporated into the Hyper Text Markup Language (HTML). You can visit php.net to learn and get ideas on how to work and tutorials.

In making a website, it takes two kinds of files, which is the main file and supporting files.

Main file

Some of the main file that needs to be known, as follows:

  • add.php, used to add data and also represented INSERT in SQL functions.
  • update.php, Used to edit the data and also represented on the SQL UPDATE function.
  • delete.php, Used to delete data and also represented on the SQL DELETE function.
  • search.php, used to display data and also represented on the SQL SELECT functionality.

 

Supporting files

In the supporting files there are 2 types, namely: (1) file supporting a general nature and (2) supporting files that are commands.

  • general.Php, Serves to store a variable of a general nature, including the server name, database name, user name, password and name.

 

  • command.Php, Serves to store functions that are mandatory, including functions to create an HTML page, the function to identify the error in the program, and the function to return to the main menu.

Integrating PHP, MySQL, Apache

PHP programs cannot walk alone in the web, thus requiring a database and web servers. Example of the database used is MySQL, while its web server is Apache. PHP program, Apache MySQLdan as his server will run on Linux.

Some basic operations are used in making the database:

  • Display data by using the SQL SELECT.
  • Entering or saving data using SQL INSERT.
  • Deleting data using the SQL DELETE.
  • Edit and update data using SQL UPDATE.

The Collapse of Darwin’s Theory (Evolution)

The collapse of Darwin's Theory (Evolution)

Charles Darwin (1809-1882) has a long name “Charles Robert Darwin” is a scientist who came from England, who found the results of research in the Galapagos Islands to support the theory of evolution. Charles Darwin called the father of evolution because it has more complete data to corroborate the theory of evolution.

Two basic core of Darwin’s theory:

1. Species that live in the present comes from the creatures that live in the past.

2. Evolution occurs because of the process of natural selection (natural selections)

Darwin’s theory has been broken by the findings of Harun Yahya, is strengthened by the publication of related research and important discoveries about early man on December 31, 2009.

Based on the results of research for many years, the entire team of researchers headed by Tim White of the University of California revealed a proof that humans and chimps have evolved separately. Indirectly, this finding has been toppled Darwin’s theory which argues that humans came from apes!

“Ardi” the Human Ancestor

Fossils of prehistoric human female sex was discovered in 1994 in Ethiopia. This is the skeleton of the oldest primate that reportedly issued a bright spot in our study of human evolution.The collapse of Darwin's Theory (Evolution)

The scientists named the fossil “Ardi”, short for “Ardipithecus ramidus”. Following the findings of the scientists on these ancient human fossils:

  • Ardi summed up as an actual human ancestors. So we are not the ancestors of apes such as Darwin said.
  • Ardi lived about 4.5 million years ago. He lived in a region in Ethiopia which is now called Aramis.
  • Ardi was a century older than Lucy, the skeleton of primates other parents who had also been found in Africa in 1974.
  • Ardi has a height of four feet or about 1.2 meters.
  • Ardi fossil consists of 125 pieces of the framework that includes the skull, teeth, pelvis, hand bones and foot bones.
  • Ardi is estimated to weigh around 110 pounds or 49 kilograms.
  • Ardi’s brain estimated with the size of a chimpanzee brain. But the ability to stand upright on two legs is a characteristic that causes this species closer to humans.
