Getting Around Cosmic Variance

Cosmic microwave background (CMB) anisotropies probe the primordial density field at the edge of the observable Universe. There is a limiting precision (“cosmic variance”) with which anisotropies can determine the amplitude of primordial mass fluctuations. This arises because the surface of last scatter (SLS) probes only a finite two-dimensional slice of the Universe. Probing other SLSs observe...

Getting around the Halting Problem

The Halting Theorem establishes that there is no machine H that can decide in all cases if a machine n halts on input m. The conjecture of this paper is that nevertheless there exist a machine H such that it can identify all the cases it is unable to decide. This become possible if the Recursion Theorem is reinterpreted as mutual necessitation rather than equivalence.

Accurate Measurement of Small Execution Times - Getting Around Measurement Errors

Engineers and researchers often require accurate measurements of small execution times or duration of events in a program. Errors in the measurement facility can introduce important challenges, especially when measuring small intervals. Mitigating approaches commonly used exhibit several issues; in particular, they only reduce the effect of the error, and never eliminate it. In this letter, we ...

Super-accuracy and super-resolution getting around the diffraction limit.

In many research areas such as biology, biochemistry, and biophysics, measuring distances or identifying and counting objects can be of great importance. To do this, researchers often need complicated and expensive tools in order to have accurate measurements. In addition, these measurements are often done under nonphysiological settings. X-ray diffraction, for example, gets Angstrom-level stru...
