How many dimensions are there, and what do they do to reality?

Posted by in categories: mathematics, quantum physics

Yet the notion that we inhabit a space with any mathematical structure is a radical innovation of Western culture, necessitating an overthrow of long-held beliefs about the nature of reality. Although the birth of modern science is often discussed as a transition to a mechanistic account of nature, arguably more important – and certainly more enduring – is the transformation it entrained in our conception of space as a geometrical construct.

Over the past century, the quest to describe the geometry of space has become a major project in theoretical physics, with experts from Albert Einstein onwards attempting to explain all the fundamental forces of nature as byproducts of the shape of space itself. While on the local level we are trained to think of space as having three dimensions, general relativity paints a picture of a four-dimensional universe, and string theory says it has 10 dimensions – or 11 if you take an extended version known as M-Theory. There are variations of the theory in 26 dimensions, and recently pure mathematicians have been electrified by a version describing spaces of 24 dimensions. But what are these ‘dimensions’? And what does it mean to talk about a 10-dimensional space of being?

Musicians Wage War Against Evil Robots

Posted by in categories: entertainment, media & arts, robotics/AI

After the release of The Jazz Singer in 1927, all bets were off for live musicians who played in movie theaters. Thanks to synchronized sound, the use of live musicians was unnecessary — and perhaps a larger sin, old-fashioned. In 1930 the American Federation of Musicians formed a new organization called the Music Defense League and launched a scathing ad campaign to fight the advance of this terrible menace known as recorded sound.

The evil face of that campaign was the dastardly, maniacal robot. The Music Defense League spent over $500,000, running ads in newspapers throughout the United States and Canada. The ads pleaded with the public to demand humans play their music (be it in movie or stage theaters), rather than some cold, unseen machine. A typical ad read like this one from the September 2, 1930 Syracuse Herald in New York:

Tho’ the Robot can make no music of himself, he can and does arrest the efforts of those who can.

China Shows Off High-Powered Laser That Can ‘Write’ In The Air

Posted by in categories: holograms, particle physics

Movie plots often use holograms to give the scene a scientific or cooler essence. However, researchers have made these futuristic scenes a reality. According to reports, Scientists in China showcased a laser that can create Chinese characters out of thin air.

Although lasers often have a long-range, you can only see them when the light lands on a surface. However, dust particles made an exception. But this is entirely different and looks like something out of a sci-fi movie.

Scientists have already used lasers to create a range of optical illusions. However, it required mediums like dust and clouds to do so. But according to reports, with the new device, researchers are able to draw patterns using ultra-short laser pulses.

J. Robert Oppenheimer cleared of “black mark” against his name after 68 years

Posted by in categories: physics, security

😗


Nearly 70 years after having his security clearance revoked by the Atomic Energy Commission (AEC) due to suspicion of being a Soviet spy, Manhattan Project physicist J. Robert Oppenheimer has finally received some form of justice just in time for Christmas, according to a December 16 article in the New York Times. US Secretary of Energy Jennifer M. Granholm released a statement nullifying the controversial decision that badly tarnished the late physicist’s reputation, declaring it to be the result of a “flawed process” that violated the AEC’s own regulations.

Tiny New Genes Appearing in Human DNA Show How We’re Still Evolving

Posted by in categories: biotech/medical, genetics

We may have parted ways with our primate cousins millions of years ago, but a new study shows just how human beings continue to evolve in ways we never imagined.

Researchers from Biomedical Sciences Research Center “Alexander Fleming” (BSRC Flemming) in Greece and Trinity College Dublin, Ireland, have identified 155 genes in our genome that emerged from small, non-coding sections of DNA. Many appear to play a critical role in our biology, revealing how completely novel genes can rapidly evolve to become essential.

New genes typically arise through well known mechanisms like duplication events, where our genetic machinery accidently produces copies of pre-existing genes that can end up suiting new functions over time.

Healthy aging: Study identifies attributes linked to longevity

Posted by in category: life extension

Previous research, oftentimes, has used a narrow definition of what healthy aging can look like.

A recent study from researchers at the University of Toronto has provided new insights into healthy aging by observing two distinct demographics in Canada: immigrant and Canadian-born older adults.

The study’s authors identified several characteristics associated with positive experiences later in life that may contribute to healthy aging, thus revising the definition of what it means to age successfully.
