We humans have again and again underestimated not only the size of the cosmos—a planet, a solar system, a galaxy, a universe, maybe a hierarchy of parallel universes—but we’ve also repeatedly underestimated the power of the human mind to understand our cosmos.
Physicists don’t all agree on the solution to the measurement problem. A penel of experts discuss the three most popular candidates and one neecomer to the scene, QBism.
In earlier essays I conceived the idea of X-Techs, i.e. technologies at the “X scale”, where X could be femto, atto, zepto, etc. The next logical step is to speculate on what hyper intelligent synthetic creatures (artilects), which are x-tech based, might have done with themselves over billions of years, given that our sun, our star, is billions of years younger than most stars in the observable universe.
You might not have have heard that physicists want $1 billion US for a project to detect neutrinos that includes building an underground tunnel, 800 miles long, between Chicago and South Dakota. The recently released Depart of Energy plan includes funding for the Long-Baseline Neutrino Experiment (LBNE) which includes an experiment to “send the world’s highest-intensity neutrino beam 800 miles through the Earth’s mantle”.
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.
