By V.L. Ginzburg

In approximately technological know-how, Myself and Others, Vitaly Lazarevich Ginzburg, co-recipient of the 2003 Nobel Prize in Physics and Editor of the assessment magazine Physics-Uspekhi, offers an perception into smooth physics, the lives and works of different renowned physicists he has identified, and perception into his personal existence and perspectives on physics and past.

Divided into 3 components, the booklet begins with a assessment of the most important difficulties in modern physics, astrophysics, and cosmology, analyzing their historic improvement and why they pose this type of problem to present day physicists and for society. half One additionally comprises information of a few of Professor Ginzburg's paintings, together with superconductivity and superfluidity. half encompasses a number of articles at the lives and works of a number of in demand physicists, together with the writer. The 3rd half is a set of articles that supply a private view of the writer, describing his own perspectives and reminiscences on a number wider issues.

Taken jointly, this selection of articles creates an stress-free overview of physics, its philosophy, and key avid gamers in its smooth improvement within the twentieth Century. certainly, it will likely be an relaxing learn for pro physicists and non-scientists alike.

5, which corresponds to a distance of 11×109 light years [154] from us. It should be emphasized that gamma-ray emission from gamma-ray bursts is most probably anisotropic. Additional strong evidence for this that z = (λobs − λsource )/λsource , where λobs is the observed wavelength of the spectral line and λsource is the wavelength in the source. 11 Remember Copyright © 2005 IOP Publishing Ltd. Some comments (astrophysics) 37 has recently been obtained [209]. Then, of course, the energy emitted is smaller than these values.

The quantity H varies with time; in our epoch, H = H0 . This quantity H0 has been measured all the time since the Hubble law was established in 1929 (Hubble assumed that H0 ≈ 500 km s−1 Mpc−1 ). Now the value H0 ≈ 55–70 km s−1 Mpc−1 has been reached using various techniques (for example, the value H0 = 64 ± 13 km s−1 Mpc−1 has been reported [75], H0 = 71 ± 8 km s−1 Mpc−1 has been obtained in [177]). 07 × 10−18 c−1 , the critical density is ρc0 = 3H02 8πG 8 × 10−30 g cm−3 . 5) Note that, from considerations of dimensionality, the Planck density is ρg ∼ c3 ∼ 4 ≈ 5 × 1093 g cm−3 .

Hence, if it were possible to trace the star motion Copyright © 2005 IOP Publishing Ltd. 32 Problems of physics and astrophysics (thirty years later) near the nucleus up to distances comparable with rg , everything would immediately become clear. 4 × 1022 cm from the Sun. Nevertheless, in this case it has been determined, using a radio interferometer, that the radiation source was of the order of astronomical unit. Optical observations of the velocity field of stars near the galactic center have shown that the motion proceeds around a mass with dimensions smaller than a light week, i.
