HAM, A Space Pioneer

The Clifford Space Geometry behind the Pioneer and Flyby Anomalies

It is rigorously shown how the Extended Relativity Theory in Clifford spaces (C-spaces) can explain the variable radial dependence ap(r) of the Pioneer anomaly; its sign (pointing towards the sun); why planets don′t experience the anomalous acceleration and why the present day value of the Hubble scale RH appears. It is the curvature-spin coupling of the planetary motions that hold the key. The...

Parnham—A Pioneer Venture

A parasite pioneer

The concept that infectious biological agents were responsible for many diseases was controversial in the midnineteenth century. But key experiments by famed scientists such as Louis Pasteur and Robert Koch eventually won over sceptics. However, some other researchers, equally convinced by this notion, and who also carried our convincing experiments in its support at the same time, have failed ...

Before then, patients with clinical problems of the locootor apparatus were treated by surgeons or pediatricians, nd those with problems resulting from trauma by surgeons r curious individuals ...

A Kosher Source of Ham

Testing content-based anti-spam systems requires a plentiful source of both spam and ham. We examine the viability of Usenet postings as a ham source. While Usenet postings have been used before for this purpose, we refine the idea and show empirically that it is the text of Usenet replies that provides the best cut of ham.
