Human Anatomy - Working of Neurons
This is a short (3:16), computer-animated video on the central nervous system.
The Central and Peripheral Nervous Systems and the Neuron
Professor George Wolfe discusses the central and peripheral nervous systems and the neuron in this video from Thinkwell's online Biology series. The video uses lecture format along with notes and illustrations on the board. Run time 08:21.
Matricism -part 1
The invention and use of a robotic system to create a painting in oils on canvas. Executed with small units or dabs of medium, the texture, pattern, and color geometries can play equal parts in expressing myriad levels of conciousness, abstraction, thought, motion, or being — beyond the obvious subject of the work.
This video offers an exploration of planet Mars, from early time up to Vicking Landing. Mars is the fourth planet from the Sun in the Solar System. The planet is named after Mars, the Roman god of war. It is also referred to as the "Red Planet" because of its reddish appearance, due to iron oxide prevalent on its surface. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the volcanoes, valleys, deserts and polar ic
Rotation, Seasons, and the Surface of Planet Mars
Mars is the fourth planet from the Sun in the Solar System. The planet is named after Mars, the Roman god of war. It is also referred to as the "Red Planet" because of its reddish appearance as seen from Earth.
A terrestrial planet, Mars has a thin atmosphere and surface features reminiscent both of the impact craters of the Moon and the volcanoes, valleys, deserts and polar ice caps of Earth. It is the site of Olympus Mons, the highest known mountain in the solar system, and of Val
Information and communication technologies (ICTs) systems now dominate our everyday lives. This unit will explain what constitutes such a system and how ICT systems work. You will also look at how ICT systems convey, store and manipulate data, and how they process data. Finally you will learn how these systems are used.
How to Determine the Value of a Coin
This clip shows how to determine the value of a coin. An antique store owner explains that it depends on several factors, including what the coin is made from, if the coin has a mint mistake and if the coin is rare. he gives tips for understand the grading system of coins.
The Real Number Set - Part 2
In this Language of Mathematics video the instructor continues his demonstration of the real number system and how it is broken down. He starts off by speaking of the number zero and the impact of the breakthrough of the 'discovery' of this number.
The Language of Mathematics (23): Cartesian Coordinate System
This video starts in an unlikely place, the instructor's car, where he begins his discussion of the Cartesian Coordinate System.
Coordinate Geometry Proof (Part 1)
The instructor uses a chalkboard to model the Cartesian coordinate system. Discussed is the midpoint of two points and how to find it using the formula for midpoint. This video is part of The Language of Mathematics series - Part 32.
The Language of Mathematics (33): Coordinate Geometry Proof, Part 2
In this segment, the instructor continues discussing the Cartesian coordinate system. Instructor uses a small chalkboard for demonstration. The viewer may want to open the screen to 'Full View' as the room the instructor is in is a little dark and his chalkboard has a lot if information.
Crohns Disease Module 10: Research
Learn about research currently focusing on abnormalities in the immune system, bacteria in the intestine, and genetics. This module will also address how you can help with research to find better ways to treat Crohns, how this will this help develop better medications, and what this research will provide.
How the Body Works: Body Frame
This is a brief video of still images with a voice that discusses the skeletal system.
Using still images, this is a brief overview of the musculoskeletal system (02:40).
In certain situations, microbial control is a necessity. For instance, our food system requires sanitary conditions and hospitals require sterilization techniques. Here we see the options available for various levels of microbial control.
An old momentum with a new twist. Kepler's second law of planetary motion, which is rooted here in a much deeper principle, imagined a line from the sun to a planet that sweeps out equal areas in equal times. Angular momentum is a twist on momentum -- the cross product of the radius vector and momentum. A force with twist is torque. When no torque acts on a system, the angular momentum
How To Completely Format A Hard Drive
Watch How To Completely Format A Hard Drive. How To Completely Format A Hard Drive. Sometimes your hard drive crashes and you need to reformat it to get it running again. Other times you might reformat it because you have a virus or you want to upgrade your operating system.
Perception: Inverted Vision
The peculiar image inversion process that takes place in the normal visual system is examined in this module. The program traces the experiences of an art student who volunteers to wear lenses that invert her visual world, connecting the adaptation process she undergoes with how the visual system functions. Graphic animations reinforce understanding of the mechanism invo
The Depression Began
By September of 1929, nervous investors began selling stocks in order to get out of the market while prices were still high. As the volume of selling increased, stock prices began to fall in October. On October 24 (Black Thursday) and October 29 (Black Tuesday), prices fell drastically as sellers panicked. By December, a staggering $40 billion in stock value had been lost. Hoover and business leaders attempted to calm Americans by assuring them that the country's economy was fundamentally sound.
