Is the Higgs boson doing its job?
At the heart of particle physics lies the Standard Model, a theory that has stood for nearly half a century as the best description of the subatomic realm. It tells us what particles exist, how they interact, and why the … Continue reading

A transistor for heat
Quantum technologies and the prospect of advanced, next-generation electronic devices have been maturing at an increasingly rapid pace. Both research groups and governments around the world are investing more attention in this domain. India for example mooted its National Quantum … Continue reading

New LHC data puts ‘new physics’ lead to bed
One particle in the big zoo of subatomic particles is the B meson. It has a very short lifetime once it’s created. In rare instances it decays to three lighter particles: a kaon, a lepton and an anti-lepton. There are … Continue reading

The awesome limits of superconductors
On June 24, a press release from CERN said that scientists and engineers working on upgrading the Large Hadron Collider (LHC) had “built and operated … the most powerful electrical transmission line … to date”. The transmission line consisted of … Continue reading

Atoms within atoms
It’s a matter of some irony that forces that act across larger distances also give rise to lots of empty space – although the more you think about it, the more it makes sense. The force of gravity, for example, … Continue reading

Good writing is an atom
The act of writing well is like an atom, or the universe. There is matter but it is thinly distributed, with lots of empty space in between. Removing this seeming nothingness won’t help, however. Its presence is necessary for things … Continue reading

‘Weak charge’ measurement holds up SM prediction
Various dark matter detectors around the world, massive particle accelerators and colliders, powerful telescopes on the ground and in space all have their distinct agendas but ultimately what unites them is humankind’s quest to understand what the hell this universe … Continue reading
