Dye sensitized solar cell

An introduction of Dye sensitized solar cell Energy resources: As we know there are some ways to get energy so that electrical can be generated, like fossil fuel, solar power, nuclear power, wind power, tidal power, geothermal power etc.1 In all these reso ...

ATLAS vs CMS On The Dimuon Resonances

Just a quick post today, to show the invariant mass distirbution of pairs of opposite-sign muons collected by the ATLAS and CMS experiment. Such plots are incredibly rich in information, as they contain the signal of ten different resonant states, and allo ...

On The Origin Of Physical Dynamics And The Reason Of Existence Of Special Relativity

The origin of physical dynamics and the reason of existence of special relativity are explored. This endeavour is started by analysing the logic of nature. Next, only mathematics is used in order to explore the dynamics of this model of physical reality. T ...

The Fundamental Nature Of Light

Did you ever wonder why both, Einstein’s relativity theory and quantum physics, in theory as well as experiment, seem obsessed with the nature of light? The velocity of light, light clocks, entangled photons, and so on – why is it always light? This preoc ...

LHCb Observes Bs Decays To J/psi F0 Pairs!

A recent paper in the arxiv describes the observation, in 7 TeV proton-proton collisions produced by the LHC collider in the core of the LHCb detector, of a new decay mode of the particle called "B-sub-s", a meson which is a bound state of a anti ...

Galileo And Relativity- But More About Inclined Planes And Fun Simulations.

Talking about relativity one should not forget Galileo's great contributions to - or perhaps in fact foundations of- physics. But more fun are Galileos researches on falling bodies and motion of projectiles, all mainly carried out by either real or Ge ...
