Frontier Of Physics: Theories of Everything Mapped

Frontier Of Physics: Theories of Everything Mapped
“Ever since the dawn of civilization,” Stephen Hawking wrote in his international bestseller A Brief History of Time, “people have not been content to see events as unconnected and inexplicable. They have craved an understanding of the underlying order in the world.” In the quest for a unified, coherent description of all of nature — a “theory of everything” — physicists have unearthed the taproots linking ever more disparate phenomena. With the law of universal gravitation, Isaac Newton wedded the fall of an apple to the orbits of the planets. Albert Einstein, in his theory of relativity, wove space and time into a single fabric, and showed how apples and planets fall along the fabric’s curves. And today, all known elementary particles plug neatly into a mathematical structure called the Standard Model. Our map of the frontier of fundamental physics, built by the interactive developer Emily Fuhrman, weights questions roughly according to their importance in advancing the field.

Rewilding Our National Parks By Paula Mackay and John Davis Rocky Wilson and his wife had settled into camp for the evening when they caught sight of a bear emerging from the brush. It was late September 1968 and the Wilsons were hunting in Fisher Basin, one of their favorite places in Washington State's North Cascades mountains. Avid outdoors people, they were no doubt accustomed to seeing black bears in the surrounding alpine meadows, where huckleberries glowed like beacons signaling the winter to come. But this bear was much bigger than the average black bear—almost seven feet long from nose to tail. Humans Have a Lot More Than Five Senses Today I found out humans have a lot more than five senses. It turns out, there are at least nine senses and most researchers think there are more like twenty-one or so. Just for reference, the commonly held definition of a “sense” is “any system that consists of a group of sensory cell types that respond to a specific physical phenomenon and that corresponds to a particular group of regions within the brain where the signals are received and interpreted.” The commonly held human senses are as follows:

Astronomers Have a Plan to Slow Down a Spacecraft When it Gets to Our Neighboring Star Planetary Habitability Laboratory/University of Puerto Rico at Arecibo The Breakthrough Starshot Initiative, announced by billionaire Yuri Milner last April with support from Stephen Hawking and Mark Zuckerberg, proposes to send a tiny spacecraft to the Alpha Centauri system, our closest neighboring stars. The craft would accelerate to around 20 percent the speed of light using a technology called photonic propulsion.

Rewilding the Future New research shows that the loss of large animals has had strong effects on ecosystem functions, and that reintroducing large animal faunas may restore biodiverse ecosystems. Rewilding is gaining a lot of interest as an alternative conservation and land management approach in recent years, but remains controversial. It is increasingly clear that Earth harbored rich faunas of large animals -- such as elephants, wild horses and big cats -- pretty much everywhere, but that these have starkly declined with the spread of humans across the world -- a decline that continues in many areas. A range of studies now show that these losses have had strong effects on ecosystem functions, and a prominent strain of rewilding, trophic rewilding, focuses on restoring large animal faunas and their top-down food-web effects to promote self-regulating biodiverse ecosystems. - - Circuit Simulator This electronic circuit simulator is highly interactive giving the feeling of playing with real components. It's very helpful for experimentation and visualization. Best of all, thanks to the power of HTML5, no plug-ins are required! Jheronimus Bosch - the Garden of Earthly Delights About this project The interactive documentary Jheronimus Bosch, the Garden of Earthly Delights provides an in-depth tour though The Garden of Earthly Delights. In a web interface the visitor will be taken on an audio-visual journey, including sound, music, video and images to enrich the storytelling. Synopsis Simulation suggests 68 percent of the universe may not actually exist According to the Lambda Cold Dark Matter (Lambda-CDM) model, which is the current accepted standard for how the universe began and evolved, the ordinary matter we encounter every day only makes up around five percent of the universe's density, with dark matter comprising 27 percent, and the remaining 68 percent made up of dark energy, a so-far theoretical force driving the expansion of the universe. But a new study has questioned whether dark energy exists at all, citing computer simulations that found that by accounting for the changing structure of the cosmos, the gap in the theory, which dark energy was proposed to fill, vanishes. Published in 1915, Einstein's general theory of relativity forms the basis for the accepted origin story of the universe, which says that the Big Bang kicked off the expansion of the universe about 13.8 billion years ago.

Humans Have Already Reached a Natural Lifespan Limit Human beings have a natural limit to their lifespan which means it is highly unlikely anyone will ever live for more than 125 years, according to new research. Scientists carried out a statistical analysis of the trends in the UK, US, France and Japan, the countries with the largest number of “super-centenarians” – those aged 110 or more. They found the average age at death for this group had not increased since 1968 and the chances of anyone exceeding 125 in any given year were less than one in 10,000, according to a paper in the journal Nature.
