Extra dimensions, gravitons, and tiny black holes

Posted by in categories: cosmology, particle physics

Why is gravity so much weaker than the other fundamental forces? A small fridge magnet is enough to create an electromagnetic force greater than the gravitational pull exerted by planet Earth. One possibility is that we don’t feel the full effect of gravity because part of it spreads to extra dimensions. Though it may sound like science fiction, if extra dimensions exist, they could explain why the universe is expanding faster than expected, and why gravity is weaker than the other forces of nature.

In our everyday lives, we experience three spatial dimensions, and a fourth dimension of time. How could there be more? Einstein’s general theory of relativity tells us that space can expand, contract, and bend. Now if one dimension were to contract to a size smaller than an atom, it would be hidden from our view. But if we could look on a small enough scale, that hidden dimension might become visible again. Imagine a person walking on a tightrope. She can only move backward and forward; but not left and right, nor up and down, so she only sees one dimension. Ants living on a much smaller scale could move around the cable, in what would appear like an extra dimension to the tightrope-walker.

Rolls Royce plans to deploy fully autonomous cargo ships by 2020 — By Matthew Griffin | Global Futurist Magazine

“Ten years ago the very idea that you could manage your life through a small glass screen, was considered almost impossible. Now few of us would want to be without one. Two years ago talk of intelligent ships was considered by many as a futuristic fantasy. Today, the prospect of a remote controlled ship in commercial use by the end of the decade is a reality.”

A Flexible Evolving Approach To Computing

Posted by in categories: computing, nanotechnology, singularity

To truly reach a fully connected world/ singularity we have to move tech into more and more bio-computing world. I do believe QC will assist us in getting the fundamental infrastructure we need for singularity.


We already must deal with computers too much rather than too little, and there is already lots of advanced computing done also for example in materials science and nanotechnology, for example molecular dynamics (MD) and Monte Carlo simulations.[2] The molecular biologist’s programs for predicting protein folding can also count as nanotechnology. Nevertheless, all of our previous articles concluded that we need more computing, and several mentioned statistics. This would sound predictable if coming from a statistical physicist with a background in computing, advertising his skills. However, we mean a more efficient computing rather than simply more.

We started the type of computing we do only recently and for reasons not yet mentioned: Given complex nano-micro compounds, materials’ characterization is difficult due to the three-dimensional complexity of the structures. We originally integrated image analysis with simulation in order to derive 3D structure from 2D images (SEM) and projections (TEM).[3,4] The most fruitful result was however the insight into how easy it is to create adaptable software that analyzes images and keeps track of all the data, calculating anything desired such as comparisons with numerical simulations, all in one integrated system.[5,6] Many of the previously discussed issues, for example error reporting, are thereby basically already automatically solved!

Adapting software sounds prohibitively difficult: Who in my lab can modify software? Nowadays everybody! Today, programming is done partially graphically, for example with LabView™, where no programming language appears anymore. We work with Mathematica and therefore with programming code, but we mostly just download parts of code and adapt them playfully until they behave as desired. To whomever such does not count as the ability to program, we cannot program!

We might finally have a way to build circuits for the world’s first quantum computers

Posted by in categories: computing, quantum physics

Another article on QC where the author is not well connected or knowledgeable about the details on QC’s advancement on entanglement. I suggest the author to learn about the use of Synthetic Diamonds in controlling and managing entanglement plus we now have a way to detect & trace high-dimensional entanglement that I shared 20 days ago. I suggest if authors wish to write on QC please make sure that you have the latest information so that your better informed.


The computers of today have just about hit their limits, and scientists around the world are scrambling to build the first viable quantum computer — a machine that could increase processing speeds 100-million-fold.

The biggest challenge in scaling up a quantum computer is figuring out how to entangle enough quantum bits (qubits) to perform calculations, but a team of engineers in the US say they might finally have a solution.

Researchers improve catalyst efficiency for clean industries: Method reduces use of expensive platinum

Posted by in categories: nanotechnology, particle physics

Nice.


Abstract: Researchers have developed a way to use less platinum in chemical reactions commonly used in the clean energy, green chemicals, and automotive industries, according to a paper in Science.

Led by the University of New Mexico in collaboration with Washington State University, the researchers developed a unique approach for trapping platinum atoms that improves the efficiency and stability of the reactions.

New record in microwave detection

Posted by in categories: computing, nanotechnology, quantum physics

Aalto University scientists have broken the world record by fourteen fold in the energy resolution of thermal photodetection.

The record was made using a partially superconducting microwave detector. The discovery may lead to ultrasensitive cameras and accessories for the emerging quantum computer.
