Quantum propulsion system for spacecraft invented
jkottke:
Aisha Mustafa, a 19-year-old Egyptian physics student, has invented a promising new quantum propulsion system for spacecraft.
Mustafa invented a way of tapping this quantum effect via what’s known as the dynamic Casimir effect. This uses a “moving mirror” cavity, where two very reflective very flat plates are held close together, and then moved slightly to interact with the quantum...

Code Simplicity » Software as Knowledge →
“Software is, fundamentally, a solid object that is made of knowledge. It follows all the rules and laws of knowledge. It behaves exactly as knowledge behaves in just about any given situation, except that it’s in concrete form. For example, when software is complex it tends to be mis-used. When software is wrong (i.e., has a bug), it tends to cause harm or problems. When people don’t...

The Static Quantum Multiverse. →
arxiv-cs:
Authors: Yasunori Nomura
We consider the multiverse in the intrinsically quantum mechanical framework recently proposed in Refs. [1,2]. By requiring that the principles of quantum mechanics are universally valid and that physical predictions do not depend on the reference frame one chooses to describe the multiverse, we find that the multiverse state must be static—-in particular, the...

The Return of the Mythical Man Month →
Underestimation of the cost, schedule, and risk of projects is common in software development and especially prevalent in mathematical software development. It is common to encounter extremely optimistic ideas about the duration and difficulty level of mathematical software projects, ironically one of the more difficult kinds of software development, as well as magical ideas about mathematics.

Abstract: Transformational music theory mainly deals with group and group actions on sets, which are usually constituted by chords. For example, neo-Riemannian theory uses the dihedral group D24 to study transformations between major and minor triads, the building blocks of classical and romantic harmony. Since the developments of neo-Riemannian theory, many developments and generalizations have...
First Simulation of Quantum Tunneling on a Quantum... →
Quantum tunneling had always been thought too complex to simulate on today’s simple quantum computers. Now a new approach to quantum computing has changed that and opens the door to more complex simulations.
