Common Errors in English Usage and More. New Physics Formula Links Quantum Mechanics And Pure Math. The notorious number Pi has succeeded in becoming even more prevalent in science.

Researchers from the University of Rochester discovered that a formula which approximates the energy levels of a hydrogen atom is the same as the one developed 360 years ago by English mathematician John Wallis to find the value of Pi. The pair of physicists realized that when the variational method was employed to calculate the energy levels of the hydrogen atoms, the formula could be simplified into the Wallis Product, the one used for Pi. The variational method is used to approximate the lower energy states of atoms, when the electrons are close to the nucleus. It is not usually used on the hydrogen atom, as hydrogen is simple enough so scientists can compute the energy levels precisely. WhyStaticClings. Ions in action.

Basic electricity. How and Why to Improve Your Cursive Penmanship. Calligraphy for Everyone!"Calligraphy, Lessons, Books, Tips, etc." Alligraphy is an art that just about anyone can do.

All you need is a pen and paper, and you're ready to do calligraphy! Indeed, it requires very few materials - you don't need very much space - and, since you can probably write anyway, you already know the basics! Calligraphy is an art form in which patience and attention to detail are more important than artistic talent. That means you don't have to be an "artist" to be good at calligraphy!

[Continued from above] . . . act as the functional units of the respiratory system by passing oxygen into the body and carbon dioxide out of the body.

Finally, the muscles of respiration, including the diaphragm and intercostal muscles, work together to act as a pump, pushing air into and out of the lungs during breathing. Nose and Nasal CavityThe nose and nasal cavity form the main external opening for the respiratory system and are the first section of the body’s airway—the respiratory tract through which air moves. The Respiratory System. What is the function of the respiratory system? The respiratory system is the group of tissues and organs in your body that enable you to breathe.

This system includes your airways, your lungs and the blood vessels and muscles attached to them that work together so you can breathe. The respiratory system's primary function is to supply oxygen to all the parts of your body. It accomplishes this through breathing: inhaling oxygen-rich air and exhaling air filled with carbon dioxide, which is a waste gas. Self-Directed Learning: A Four-Step Process. What Is Self-Directed Learning? Self-directed learning is not a new concept.

In fact, much has been written about it. Unfortunately, however, it is a notion that has a variety of interpretations and applications in the corporate training arena. Typical, narrow interpretations involve simply giving learners some sort of choice in their learning. For example, allowing learners to select one or more courses from a curriculum, or, in cases of structured on-the-job training, allowing employees to choose what pre-designed modules (e.g., a video tape, workbook, special reading, etc.) to complete. Literary Devices and Terms. The periodic table of education technology. We had a crazy idea over the weekend here at Daily Genius.
