Amazing Science: Physics Postings

Amazing Science: Physics Postings | Learning Physics | Scoop.it

Physics is the natural science that involves the study of matter and its motion through space and time, along with related concepts such as energy and force. More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy. Over the last two millennia, physics was a part of natural philosophy along with chemistry, certain branches of mathematics, and biology, but during the Scientific Revolution in the 17th century, the natural sciences emerged as unique research programs in their own right.

Roller Coasters

Roller Coasters | Learning Physics | Scoop.it

Many extreme roller coaster these days have vertical loops. Have you noticed that these loops are never circular? Why is this?

They all, also, seem to have the same similar ‘inverted teardrop’ appearance. Why is this?

Clearly there is the same physics and mathematics involved in their designs. Let’s take a look and see if we can derive a formula to describe their shape.

Why are roller coaster loops not circular?

Microscale gravity: Gravitational energy measured with 100,000 times better precision than in previous experiments

Microscale gravity: Gravitational energy measured with 100,000 times better precision than in previous experiments | Learning Physics | Scoop.it
Bouncing neutrons probe dark energy on a table-top, measuring gravity's effects at the quantum scale finds no deviations from Newton's laws.

In this week's Physical Review Letters2, a team led by physicist Hartmut Abele at the Technical University of Vienna shows that the ordinary laws of gravity are still valid even when measured over the scale of a few micrometres. The researchers measured quantized gravitational energy levels with a precision that is 100,000 times better than in previous experiments3.


That precision is sufficient to test some proposed explanations for dark energy — the unknown force that seems to be accelerating the expansion of the Universe. Some models of dark energy put constraints on particular gravity-like forces that would subtly distort the quantum levels at these micrometre scales. “It’s really a beautiful experimental tour de force,” says Geoffrey Greene, a physicist at the University of Tennessee in Knoxville who was not involved in the study.


'Chameleon' dark energy is one such hypothesized force. It derives its name from the way the range over which it acts is reduced drastically for dense objects, which would account for why we fail to see it in Solar System measurements. Such a 'fifth force', existing alongside the known electromagnetic, strong, weak and gravitational forces, would tweak the neutrons' energy levels from those predicted by gravity alone, says Amol Upadhye, a theoretical physicist at Ewha Womans University in Seoul, who was not part of the research team.


The team’s results put a limit on how strong that force could be. “This limit is one hundred times better than the previous such limit,” says Upadhye. This does not eliminate chameleon theories as possible explanations for the dark energy, he adds. “There are still some seven orders of magnitude to cover … but this goes a long way towards closing that gap.”


The results also constrain the properties of a potential candidate for dark matter, the substance thought to make up 85% of matter in the Universe but which seems to be undetectable except for its gravitational pull at cosmic scales. Very light hypothetical particles called axions would cause a deviation from the ordinary law of gravity at short distances. The absence of such an effect in this latest study limits how strong these interactions could be.


"It's truly remarkable that experiments such as this are possible at all," says Upadhye. The researchers call the technique gravity resonance spectroscopy, because it mirrors other kinds of spectroscopy, which measure the energy states of electrons in the electromagnetic field of an atom. These have found a wide range of uses — from determining the composition of faraway galactic objects to atomic clocks. “This first application of the new technology is a big step," says Greene.

"Excellent educational content can be found on YouTube. However, not every teacher can access YouTube in his or her classroom. That's why a few years ago I compiled a big list of alternatives to YouTube. Over the years some of those sites have shut-down, started charging a fee, or have switched into another market. So this evening I went through and eliminated some sites from the list and added a few new ones."

* The National Film Board of Canada

* Vimeo

Each link provides a short description of what the site has to offer. You will also be able to access the fill list of sites through this post.
And if you are trying to search for a video you might want to try out the Custom Search Engine he has created through Google. This search engine is accessible at this link: http://www.freetech4teachers.com/2013/08/a-youtube-free-video-search-engine.html

Videos are a great tool to quickly engage students in learning and this list of websites as well as this search engine are great options to put in your toolbox.

Fox eBook's curator insight, July 26, 2013 7:17 PM

Balancing concise mathematical analysis with the real-world examples and practical applications that inspire students, this textbook provides a clear and approachable introduction to the physics of waves. The author shows through a broad approach how wave phenomena can be observed in a variety of physicalsituations and explains how their characteristics are linked to specific physical rules, from Maxwell’s equations to Newton’s laws of motion. Building on the logic and simple physics behind each phenomenon, the book draws on everyday, practical applications of wave phenomena, ranging from electromagnetism to oceanography, helping to engage students and connect core theory with practice. Mathematical derivations are kept brief and textual commentary provides a non-mathematical perspective. Optional sections provide more examples along with higher-level analyses and discussion. This textbook introduces the physics of wave phenomena in a refreshingly approachable way, making it ideal for first- and second-year undergraduate students in the physical sciences.
