What is a Higgs boson?
The discovery of the Higgs boson was a triumph for particle physics. Its discovery completes the tremendously successful Standard Model of particle physics. Of course, we know there are other phenomena — like dark matter, the dominance of matter over anti-matter, the mass of neutrinos, etc. — that aren’t…
Who discovered Higgs boson?
When Paul Glaysher was approaching the end of his master’s degree in 2012, everyone was talking about the Higgs boson. After two years of smashing protons together, CERN’s Large Hadron Collider was about to bring the mysterious particle—it helps explain how the universe got its mass—out of the theoretical…
Scientific theories vs laws
Words like “fact, ” “theory, ” and “law, ” get thrown around a lot. When it comes to science, however, they mean something very specific; and knowing the difference between them can help you better understand the world of science as a whole. In this fantastic video from the It’s Okay To Be Smart YouTube…

Latest News on Higgs boson
Figure 1: The observed signal strengths (μ) and uncertainties for different Higgs boson decay channels and their combination for mH=125.36 GeV. Higgs boson signals corresponding to the same decay channel are combined together for all analyses. The best-fit values are shown by the solid vertical lines…

Gravitational pull between Earth and Moon
F = G m M / r2 in which F is the gravitational force between the two bodies, m and m are their masses, and r is the distance between them, has the same value regardless of which object is thought of as pulling on the other. In other words, both Laws imply that the force the Earth exerts on the Moon is…

Higgs field and gravity
One of the questions I get most often from my readers is this: Since gravity pulls on things proportional to their mass, and since the Higgs field is responsible for giving everything its mass, there obviously must be a deep connection between the Higgs and gravity… right? It’s a very reasonable guess, but — it turns out to be completely wrong. The problem is that this statement…

Gravitational field strength Definition
This is a way of measuring how much gravity there is. The formula is: weight/mass = gravitational field strength. Gravitational field strength = Weight/mass unit is N/kg Weight = mass x gravitational field strength unit is N On Earth the gravitational field strength is 10 N/kg. Other planets have different gravitational field strengths. The Moon has a gravitational field strength…
