Vertical Aircraft Navigation

After a short introduction into vertical navigation related terminology, the basic formulae are derived allowing a pilot of a fixed-wing aircraft to calculate the lateral distance needed to make a given descent and to calculate the rate at which the airplane has to descend to remain on a chosen glide slope.

Principles of Radio Astronomy and Ground Based CMB Detection

After an introduction to measures of electromagnetic radiation and the nature of blackbody radiation, an account is given regarding the discovery and origin of the cosmic microwave background (CMB). The basic concepts of radio astronomy are then explained, followed by a methodology to detect the CMB radiation from earth's surface.

Numerical Models for the Expanding Universe

This project gives an overview of the equations describing the expansion of a homogeneous and isotropic universe. Common mathematical software, which can be run on a standard computer, is used to numerically solve the equations. The results for different compositions of the universe are presented, identifying the model which best matches recent cosmological observations.

The Milky Way Experiment

The aim of this experiment is to observe the effects of the differential rotation of the Milky Way and to demonstrate that the hydrogen in our galaxy is concentrated in a disc and in arm like structures.
