Dear Colleagues
Today Wednesday, at 17:15, the Kolloquium series of SS05 will terminate
with a talk on
Astrophysics (see abstract below). From 16:45, there will be tea and
coffee in front of the
lecture hall 16 G 05 at the Irchel Campus of the University (the usual
place!).
For directions or further information, go to

Please note: There will be no talk in the last week of the semester.
With best regards,

In the context of the new scientific orientation of the Laboratory of
Astrophysics of the EPFL, I will present three interconnected topics in
extragalactic astrophysics: (i) COMOGRAIL is a photometric monitoring
program of already known lensed quasars. Started in September 2004, it
will provide, within 3 years, Ho determination with a precision better
than 2%, including systematics. The project also involves VLT and HST
follow up and the use of the most advanced image deconvolution
softwares. (ii) Strong lensing can be efficiently used in the study
(lensed) quasar accretion disk, by following the microlensing chromatic
variations induced by the lensing galaxy. Our VLT spectrophotometric
monitoring of the Einstein Cross is currently searching for chromatic
microlensing events in order to constrain the energy distribution of
the quasar accretion disk, at a resolution of a few micro, possibly
even nano arcseconds. (iii) I will present the first results of a
direct spectroscopic VLT and HST study of quasars hosts galaxies at low
redshift (z<0.3).

Dear Colleagues
Today Wednesday, at 17:15, the Kolloquium series of SS05 will feature
again an Einstein-related talk:
Prof. Jarlskog will tell us more about how Einstein got his Nobel Prize.
From 16:45, there will be tea and coffee in front of the lecture hall
16 G 05 at the Irchel Campus of the University
(the usual place!).

How Did Einstein Get the Nobel Prize ?
Cecilia Jarlskog
Lund University
The talk will address the following items:
-Alfred Nobel and his Prizes
-Selection of the laureates and a few examples
-A more detailed discussion of the Prize to Einstein
-Future prospects

Dear Colleagues
Today at 17:15, the Kolloquium series of SS05 will continue with the
Abschiedsvorlesung of Peter F. Meier (see
abstract below).
From 16:45, there will be tea and coffee in front of the lecture hall
16 G 05 at the Irchel Campus of the University
(the usual place!). For directions or further information, go to
http://www.physik.unizh.ch/teaching/kolloquium05/kolloquium.html
Note that tomorrow there will be a Workshop dedicated to Peter F. Meier
(for program see attachment).
You will notice that there is still one slot of the Kolloquium program
open: June 29, the last date before SS05 ends.
Suggestions for a speaker are welcome.
With best regards,

Abstract:
Computer Simulations in Science (Abschiedsvorlesung)
Peter F. Meier
Physik-Institut, Universität Zürich
A critical examination of advantages and limits of computer simulations
in science is presented. The interplay between reality, model, and
treatment is of essential relevance and must be addressed. Do numerical
calculations help us in understanding nature, or do they perhaps hide
away the essential issues or even mislead us ? Some of these questions
are examined using well known examples from statistical mechanics and
solid state physics. In particular, the usefulness of computer
simulations for an explanation of high temperature superconductivity is
discussed.
