Every day more Ukrainian children become victims of war Russia is waging on Ukraine.
We urge to save them. Close the sky over Ukraine.

Incredible Georgian people who understand that friends must be supported! 🇬🇪🇺🇦 Grateful to everyone in Tbilisi and other cities who came out in support of Ukraine and against the war. Indeed, there are times when citizens are not the Government, but better the Government.
The rarest of a binary star system, a double pulsar, confirms Einstein's predictions and puts tight constraints on alternative gravitational theories.

@LeoPantsulaia and the last one is relates the integrated magnetic field around a closed loop to the electric current passing through the loop. J includes magnetization current density as well as conduction and polarization current densities.
@LeoPantsulaia The third is about how a magnetic field will interact with an electric circuit to produce an electromotive force (EMF) it also known as electromagnetic induction.where ∇ × is the curl operator and again E(r, t) is the electric field and B(r, t) is the magnetic field
@LeoPantsulaia The second law states that the magnetic field B has divergence equal to zero . where ∇ · denotes divergence, and B is the magnetic field.
@LeoPantsulaia The first one is a law relating the distribution of electric charge to the resulting electric field . ∇ · E is the divergence of the electric field and ρ is the volume charge density
@LeoPantsulaia თერმოდინამიკის მეორე კანონი არის როცა ენერგია გარდაქიმნება სითბურ ენერგიად, ხოლო პირველი კანონი ენერგიის მუდმივობის კანონს წარმოადგენს , ამ დროს ერთი სახის ენერგია გარდაიქმნება მეორე , სხვა სახის ენერგიად . შეგვიძლია ეს მოვლენა თერმოდინამიკის პირველი კანონით ავხსნათ .
