It’s a powerful technique, but small uncertainties at each step can add up, something critics argue may be behind the Hubble ...

"Precision in these measurements is critical, as even subtle discrepancies could signal deviations from the model — ...

During the mid- to late-twentieth century, quantum physicists picked apart the unified theory of physics that Einstein’s theory of relativity offered. The physics of the large was governed by gravity, ...

A research team from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) has directly measured the masses of two highly unstable atomic nuclei, phosphorus-26 and sulfur-27.

Why does lead behave so differently from every other atomic nucleus when struck by electrons? A team of physicists at ...

Recently in my physics lab, students were having trouble with the difference between mass and weight. I had ready answers---it’s a topic I’ve gone over hundreds of times. But after I explained that ...

This morning on BBC Radio 4, the mathematician Roger Penrose, physicist Basil Hiley, and philosopher Simon Saunders had a lively discussion about the “measurement problem in physics” with broadcaster ...

Any exam preparation is a rigorous process which requires an overall understanding of the concepts and basics discussed in a chapter. If we talk about the Class 11 Physics, then one thing to be ...

Uncertainty affects the accuracy with which measurements can be made in quantum physics. To reduce this uncertainty, physicists have learned to "squeeze" certain measurements. Researchers are now ...

Class 11 Physics Notes for Chapter 2 Units and Measurements (Class 11 Physics NCERT textbook) are available here. This part is the continuation of Part I, the topics covered in this part are: Order of ...
