... Stellar Evolution is driven entirely by the never ending battle between Pressure and Gravity . As imbalances are reached, the star is driven to find a new Energy source. ... Pressure and gravitational forces are equal, the star is stable and its core is sufficiently hot to fuse Hydrogen into Helium More about main sequence stars . ... The luminosity generated by the core fusion of Helium into Carbon is far greater than the shell luminosity associated with the fusion of Hydrogen into Helium. ...

. This schematic diagram shows how scientists think the universe has evolved from the Big Bang to the present day. Data from the UKIRT, VLT, and Subaru observatories allowed astronomers to take four precise and comparable snapshots of the universe when it was, 2, 4, 6 and 9 billion years old, each containing hundreds of star-forming galaxies. By comparing the different snapshots, astronomers were able to accurately track what has changed over the past 11 billion years. // illustration by CXC/NASA/NOAO/KIPAC

... Several attempts to discover the FICN signal in VLBI nutation series made during last years failed. ... We investigated several VLBI CPO series by means of spectral and wavelet analysis. It has been shown that there are several periodic signals with close amplitude around the expected FICN period without any prevailing one that can be reliably associated with the FICN. ... DATA ANALYSIS We analyzed several CPO series obtained in IVS analysis centers by means of spectral and wavelet analysis. ...

... The goal of this course is to introduce some -- very interesting -- basic examples and notions of combinatorial game theory, following the book "How to win your mathematical games", by Berlekamp, Conway and Guy. ... So, for every game there is a winning strategy, and to find one one can use the well-known idea of winning/losing positions. ... Temperature theory. We will see the limits of the association of numbers and games: some positions can not be associated to a single real number! ...
