Measuring the value and the impact of a scientist on her field of research using as data her scientific papers, the number of citations these papers got, and the prestige of the scientific journals…

The fourth FQXi essay contest is underway. There is a lot questionable about FQXi and what it at times supports, but this year’s topic is just so clearly up my alley that I simply cannot resist:…

The deeper we look into the universe, the deeper we look back in time. When in the night sky you see planets like Jupiter and Saturn, you look about an hour back in time. Look at the stars, and you…

Was Einstein wrong about ?  No, the equation correctly relates an objects rest mass to its energy content. However, in 1952, Herbert Ives published Derivation of the Mass-Energy Relation in…

Top quarks are most often produced in pairs at hadron colliders. The reason of this fact is that the strong interaction, which produces most of the reactions between the projectiles, is flavor-blind…

In this blog I will derive the Einstein field equations starting from the Hilbert action.  Since there are only two terms in the Hilbert action, one of which is left alone, there is not that…

I like to explain stuff so that people like you and me think “aha!”, and not, “this guy knows a lot; I better agree though I have no clue what he is talking about”. In this manner, let me again…

Well, not really a "true" queen sacrifice, but it is still a nice little combination the one I played against a strong 1st category player today at the "Baracchi Memorial" in Venice, a one-day rapid…

QUATERNIONS AND GROUP THEORY

What I didn't account for in my last blog post was that there is a first order energy shift due to classical physics.. to IS NOT relativitstic in nature.  This can be understood using E=hf and…
