Law of gravitational pull
In my two previous posts, I explained how understanding the laws of the universe and the differences between perception and reality can help businesses to do better marketing. In this one, I take these concepts a bit further to show marketers how they can use gravity - the least understood of the four…
Higgs particle
[Updated slightly, to reflect the fact that a Higgs of some type has been discovered, as announced at the LHC on July 4th, 2012.] Most of us learned in school, or from books, that all the materials around us — everything we eat, drink and breathe, all living creatures, and the very earth itself — are…
Gravitational force Problems
Using physics, you can calculate the gravitational force that is exerted on one object by another object. For example, given the weight of, and distance between, two objects, you can calculate how large the force of gravity is between them. Here are some practice questions that you can try. Practice…
Theoretical energy
Group Overview The last decades have seen exciting progress in high energy physics with the establishment of the Standard Model of the quark and lepton constituents of matter and their interactions. A unified gauge theory of weak and electromagnetic interactions received experimental confirmation through…
Laws of Gravitation by Isaac Newton
Born in England, Isaac Newton was a highly influential physicist, astronomer, mathematician, philosopher, alchemist and theologian. In 1687, Newton published Philosophae Naturalis Principia Mathematica, what is widely regarded to be one of the important books in the history of science. In it he describes universal gravitation and the three laws of motion, concepts that remained…

Newtonian gravitational constant
Figures Figure 1: Sketch of the experiment. The Rb atom interferometer operates as a gravity gradiometer and the W masses are used as the source of the gravitational field. For the measurement of , the position of the source masses is alternated between configurations F and C. Plots of gravitational acceleration ( az ) produced along the symmetry axis by the source masses are…

Higgs boson LHC
Today during the 50th session of “Rencontres de Moriond” in La Thuile Italy, the ATLAS and CMS experiments presented for the first time a combination of their results on the mass of the Higgs boson. The combined mass of the Higgs boson is mH = 125.09 ± 0.24 (0.21 stat. ± 0.11 syst.) GeV, which corresponds to a measurement precision of better than 0.2%. The Higgs boson is an…
