I have a guestbook:  Do you have comments?
I am interested in the dynamics of nonlinear systems, spatio-temporal phenomena, propagating waves, dissipative structures ... For people who are already aware of these are just general words, can say more definitely:
heart the heart, and the

Belousov-Zhabotinsky (BZ) reaction

The BZ reaction is a chemically active medium which maintains self-oscillations and propagating waves. For an observer this is seen as a periodic change of color from red to blue, or a propagating blue wave on the red background. Very impressive... Click here to read how the BZ reaction works and how to make it work.

here is an experimental record (mpeg movie, 236 k) of the dynamics in the system. Arrows point at the regions of interest: rotating spiral wave (chemical vortex), and zone of chaotic oscillations.

rotating vortex: Archimedian spiral rotating vortex: log spiralComputer simulations of the BZ reaction. Rotating vortices in the form of Archimedian spiral (left) and logarithmic spiral (right). ?Holes? in the centers - the cores of vortices. The dynamics  is described in refs. [17,20,24] of my reference list .

Scheme of a SAN Cell  A scheme of a cardiac cell, namely, a SAN cell. To properly simulate such a cell, we need to account for both membrane currents and balance of intracellular ions and the function of Sarcoplasmic Reticulum. My current interest in this is the effect of ACh on a cardiac myocite.

animated heart  Computer simulations of the heart.  A pulse is initiated at the bottom of the right ventricular. Only the front of the propagating pulse is shown.

Several more animations of heart dynamics with LR kinetics are here

N.B. above are animated pictures. If you see just static figs, please, upgrade your web browser.


Simple quiz in physics (my hobby)

Three balls are started to move with equal velocities v from the same position A. In what order the balls come to B if the landscape is as in the picture? (v is high enough for red ball to reach B; no friction or other bad things).

The solution does not require taking path integrals, just click below:


My schools: FMSh-18 and MFTI and around ...


My thanks

to Professor C. Frank Starmer who enabled me to compose this home page on his machine. He is also the coordinator of the project Laboratory Without Walls. This project includes free of borders communication between people having similar interests in science and beyond. These are not just words, LWW cooperation has yielded interested scientific results and is in progress.
