Yale: Frontiers and Controversies in Astrophysics, Lecture 21

Class begins with a review of the mysterious nature of dark matter, which accounts for three quarters of the universe. Different models of the universe are graphed. The nature, frequency, and duration of supernovae are then addressed. Professor Bailyn presents data from the Supernova Cosmology Project and pictures of supernovae taken by the Hubble Space Telescope. The discovery of dark energy is revisited and the density of dark energy is calculated. The Big Rip is presented as an alternative hypothesis for the fate of the universe.

Marcus du Sautoy: Symmetry, reality's riddle

The world turns on symmetry -- from the spin of subatomic particles to the dizzying beauty of an arabesque. But there's more to it than meets the eye. Here, Oxford mathematician Marcus du Sautoy offers a glimpse of the invisible numbers that marry all symmetrical objects.

How Damaging is Radiation?

What is radiation? Are all types harmful? What are the most common sources of damaging radiation? Most people view radiation as harmful and negative without understanding what makes it potentially damaging and which forms should be avoided. For example, many felt radiation from mobile phones probably caused cancer but few focused on the carcinogenic effects of UV rays.

Whiter than White, Blacker than Black and Greener than Green: The Perception of Color - UWM Science Bag

What do we mean when we say that a geranium is red, an orange is orange or white white? When, in fact, and why is white white, and what is color? Answers to these and other intriguing questions about the nature of light, the color of common objects, and the way in which the human eye perceives color can be found in this program.

Charge and Electric Field of a Hollow Conductor

A conducting sphere is charged with a Wimshurst Machine. Charge is removed from the outside of the sphere and placed on an electroscope, which deflects outwards. When the procedure is done for the inside of the sphere, it is found that no charge resides there. Conducting balls are used to examine the effect of the sphere's electric field on the displacement of charge. The field induces opposite charges on the balls and, again, the effect is shown using the electroscope.

Plasma: The 4th State of Matter

Plasma is widely considered to be the fourth state of matter due to its unique properties. Plasma is a gas in which the atoms are ionized, meaning there are free negatively charged electrons and positively charged ions. This collection of charged particles can be controlled by electromagnetic fields and this allows plasmas to be used as a controllable reactive gas. The electronics industry uses this concept to etch very small patterns into silicon to make our modern day devices smaller and more efficient.

This movie was produced by students Bobby Bruce and Michael Sweatt for the A. James Clark School of Engineering's 2008 Vid/Terp competition.

Atoms and Isotopes

Most people recognize that atoms are the fundamental building blocks of all matter around us. An atom itself is composed of protons, neutrons and electrons. The simplest atom is the hydrogen atom because it consists of only one proton and one electron. If a neutron is added to the nucleus, the atom is still hydrogen, just a more massive version. Atoms of the same element (i.e. those with the same number of protons) but different numbers of neutrons are called isotopes.

Yale: Frontiers and Controversies in Astrophysics, Lecture 20

ASTR 160 - Frontiers and Controversies in Astrophysics
Professor Charles Bailyn
Spring 2007
Source: Yale University, Open Yale Courses

This lecture introduces an important concept related to the past and future of the universe: the Scale factor, which is a function of time. With reference to a graph whose coordinates are the Scale factor and time, the problem of dark matter is addressed again. Cosmological redshifts are measured to determine the scale of the universe. The discovery of the repulsive, anti-gravitational force of dark energy is explained. The lecture concludes with discussion of Einstein's biggest mistake: the invention of the cosmological constant to balance gravity.

Khan Academy and the Effectiveness of Science Videos

It is a common view that "if only someone could break this down and explain it clearly enough, more students would understand." Khan Academy is a great example of this approach with its clear, concise videos on science. However it is debatable whether they really work. Research has shown that these types of videos may be positively received by students. They feel like they are learning and become more confident in their answers, but tests reveal they haven't learned anything. The apparent reason for the discrepancy is misconceptions. Students have existing ideas about scientific phenomena before viewing a video. If the video presents scientific concepts in a clear, well illustrated way, students believe they are learning but they do not engage with the media on a deep enough level to realize that what was is presented differs from their prior knowledge. There is hope, however. Presenting students' common misconceptions in a video alongside the scientific concepts has been shown to increase learning by increasing the amount of mental effort students expend while watching it.

What's new @CERN ? n°3 GRID computing

Hundreds of millions of collisions per second -- Detectors collecting data to analyse 24/7 : the LHC and its experiements generate millions of gigabytes of data. The Computing Grid, a huge, worldwide network of computers was invented to manage, process and store these phenomenal volumes of data. How does it work? Who uses it ? What is its performance since the LHC started up nearly two years ago? What are its other applications outside particle physics ? We're going to review all this with Oliver Keeble, Computing engineer at CERN who works on the computing Grid.

MIT Physics Demo -- Magnetic Deflection of a TV Image

An cathode ray tube (CRT) television is connected to a video camera. When a strong magnet is brought close to the television screen, the image becomes warped and discolored.

While many new televisions use flat screen technology, older CRTs produced images by firing electron guns (one red, one green, one blue) through the television body onto the back of the screen. When a magnet is brought close to the screen, it deflects the paths of the electron beams and distorts the picture. A strong enough magnetic field can even create a hole in the electron beams, causing a black spot on the picture.

This TV has been subject to many magnet encounters, which has permanently damaged the picture.
