Who stop at femtotech? Physics also allows attotechnology and beyond to zeptotechnology. These “X-Tech” possibilities provide a potential solution to the Fermi Paradox (“where are all the nonhuman civilizations?”). We may need a paradigm shift from SETI to SIPI — the Search for Infra Particle Intelligence!
A recent paper from Dr. Lloyd discusses limits to digital computation as we now employ it, but he further shows that the universe itself is a sort of vast quantum computer.
Einstein famously said that imagination is more important than knowledge – but there’s more to it.
Since our recent work on finding the world’s simplest and cheapest memristor we set ourselves to demonstrate its applications. Scientists have discussed possibilities and efficiencies gained by using memristors in analog circuit design, such as reduction in area and power of a circuit. However, a demonstration using real memristor is missing. Let us see this for the case of an amplifier, a basic unit in analog circuit design.
Recently, there has been widespread confusion about digital physics relating it to the simulation argument. [updated]
There’s been a lot of buzz lately in the science blogosphere about a recent experiment where physicists created a gas of quantum particles with a negative temperature – negative as in, below absolute zero. This is pretty strange, because absolute zero is supposed to be that temperature at which all atomic motion ceases, where atoms that normally jiggle about freeze in their places, and come to a complete standstill.
Can we find evidence for quantum gravity? That’s a major puzzle in Physics. This might be possible using a simple table-top experiment, according to Jacob Bekenstein, at the Hebrew University of Jerusalem.
