Two New Sciences . ... I greatly doubt that Aristotle ever tested by experiment whether it be true that two stones, one weighing ten times as much as the other, if allowed to fall, at the same instant, from a height of, say, 100 cubits, would so differ in speed that when the heavier had reached the ground, the other would not have fallen more than 10 cubits. ... Galileo Experiements: . ... Class Discussion: How can Galileo "slow down gravity" so he can accurately time it? ...

Context. Thermal emission by stochastically heated dust grains (SHGs) plays an important role in the radiative transfer (RT) problem for a dusty medium. ... Aims: We define an appropriate problem for benchmarking dust emissivity calculations in the context of RT simulations, specifically including the emission from SHGs. ... It also includes a series of analytically defined radiation fields to which the dust population is to be exposed and instructions for the desired output. ...

... Perhaps the most important thing to note in this context is that SM has a command line editor, which allows you to recall previously typed commands (use the up arrow to scroll back through them) and either them, or edit them. ... identification plots an identification line at the top of the graph, giving the date and some other information, of your choice. label allows you to plot a label on the graph, at the current location. ... You can change the size of the plot window with the location command....

... Portrait of Galileo Galilei (in 1636) by Justus Sustermans. ... We are about three-quarters of the way through the IYA, the International Year of Astronomy. It is thus timely to think about the successes of the year and, as this ASP annual meeting title indicates, forge a path to a future of continued public engagement in astronomy. In this context of public understanding and appreciation of science, it is important to note the world view into which Galileo Galilei was born (1564). ...

... One of the most obvious features of the plasma state is the rich variety of wave motions which plasmas can support. ... Some important wave parameters in general are: . ... The way the dispersion relation is calculated depends on the adopted plasma theory , which also determines the available wave modes. ... the more complicated the medium is, the more wave modes it support (we cannot have, e.g., ion plasma waves if ion motion is neglected in the first place, no matter how hot plasma is considered!)...

... Armagh Observatory, College Hill, Armagh BT61 9DG, +44 (0)28 3752 2928 . ... Polarimetric measurements of six Jupiter Trojans asteroids. ... Trojan asteroids orbit in the Lagrange points of the system Sun-planet-asteroid. ... We have obtained high-accuracy broad-band linear polarization measurements of six Jupiter Trojans of the L4 population and tried to estimate the main features of their polarimetric behaviour. ...

... Development of the CATS, connected with the fast inreasing of data, direct our interests to the search systems to accelerate a search for information with keywords. Via Internet we have looked for a system of the fast index search GLobal IMPlicit SEarch adn its hypertext extension WebGlimpse (U. Manber et al., 1997). ... It is even possible for the search to efficiently cover remote pages linked from your pages (WebGlimpse will collect such remote pages to your disk and index them). ...

Next: Student Briefing Up: Case Study 1: The Previous: Case Study 1: The . This PBL exercise was used as the principle assessment item for a 1st year introductory cosmology course. About 40 students were enrolled. These students were required to have a reasonable high-school maths and physics background. Students were required to do the exercise in their own time: little class time was made available for it. ... Paul Francis 2001-06-21 ...
