As far as I can tell, residual strong nuclear force is just another name for the strong nuclear force?

Are you talking about quantum chromodynamics?

Interactions are not dimensions. Same as electricity is not distance and horses are not cardinal directions.

Not in terms of spatial dimensions, no. But like I said, it could be a misinterpretation, since I'm just starting college. Just a musing I had. I was thinking in terms of fields and things that seem to be constant to all matter. Like gravity being caused by all energy, not just mass, and thus why it's separate from the Higg's Field.

I don't pretend to think it's accurate, it was mostly a way for me to understand how the universe could exist in 11 dimensions, or 26(!?!) in terms I could comprehend.

I'm pretty sure the extra dimensions in string theory are literal spatial dimensions, though small ones.

The reason for keeping electricity together with magnetism is actually pretty clever - it's because one is another, depending on the velocity relative to the observer. It would make no sense if an actual physical phenomena was dependent on the observer, hence electromagnetism as a single thing.

Also, magnetism can be pretty accurately described as a relativistic effect of electricity.

A team Swiss scientists of the EPFL technology institute has managed to let a monkey regain mobility after partial paralysis, using an electronic device implanted in the brain that records motoric brain activity, and sends it to the leg using wireless signals. They've already started trials with human patients.

The monkey tests were done in China, to circumvent strict EU regulations on monkey testing.

Who needs a spine when you can have wifi, right?

Heh, wow. Microsoft must want this guy really bad:

The Dutch quantum computer expert and professor at Delft Technical University, Leo Kouwenberg, has been hired by Microsoft. But instead of coming to work everyday, work will come to him. He will keep teaching at the Delft University, and Microsoft is going to build a quantum computer lab in our university for him to do research at.
Currently, the professor does his research in an already existing quantum lab at the university, of which he is one of the founders, and which curently sees over a hundred scientists and technicians doing fundamental research on the building blocks of quantum computers.

Damn, building a whole new lab just to employ one guy. Makes sense though, Delft University is where the breakthroughs were and are being made.

With Trump as head of state, we should be wary of industrial espionage though.. /sarcasm

EDIT: together with Kouwenberg, Microsoft also hires the Danish phycisist Charles Marcus. Marcus and Kouwenberg have been working for years, doing research mainly into so called 'topological quantumbits', which are less susceptible to discturbance than ordinary quantum bits.

Kouwenberg was the first, a few years ago, to realize superconductive nano wires, which would be very suitable for topological quantum bits. Marcus is working on something similar.

Kouwenberg says even he himself is somewhat surprised by his career step. "I started work here as a student. I never thought that what we did would ever be of use for anything at all"

EDIT: hmm. perhaps Microsoft wants to upgrade Deep Mind to a quantum network and would rather it be across the atlantic so they can nuke it when it awakens  :D

That reminds me of one interesting article I read a little while back; apparently, nanotubes are a promising avenue for a single photon light source. This would be very useful for developing an optical quantum computer, which would be a nice way to do a lot of quantum calculations at relatively benign conditions, versus the current need for heavy chilling etc. with physical qubits.

The New York Times wrote an article about Microsoft's plans with the scientists. They're going to try and build an actual topological quantum computer using Kouwenhoven's nanotubes.

It seems logical to me. Quantum expert works in two places simultaneously, one of them being at a distance, and it is currently unknown what the end result will be...   :P

Spooky peer review at a distance.

Anyway, its nice seeing that there's so much investment going into quantum computing. I was scared interest in it would've down a bit after D-Wave was pitted against intel machines and didn't quite perform in a way convincing enough to prove it is actualy making productive use of quantum phenomena, though it was still rather impressive in its own right.

Wouldn't this be affected by the recent fabricated results controversy?

"There are two kinds of scientific progress: the methodical experimentation and categorization which gradually extend the boundaries of knowledge, and the revolutionary leap of genius which redefines and transcends those boundaries. Acknowledging our debt to the former, we yearn nonetheless for the latter."

I have tried to explain this so many times, unsuccessfully. Thanks, Sid!
