Dear Editor-in-chief, Matthew Chalmers:

First, we thank you for your fascinating account from 10 September 2018,
The Large Hadron Collider: 10 years and counting and for your 31 August 2018 article,
The day the world switched to particle physics.

We also found Ruth Leopold’s posting of Lucio Rossi’s work from 31 August 2018,
Viewpoint: Lessons from the accelerator frontier. It is all quite fascinating.

In the photograph of the proton tracks, could you tell us at what resolution are they measuring? What would be the size of each of the two protons? How much smaller can the Large Hadron Collider see?
Can it “see” things smaller than 1×10^-16 meters? (certainly below 10^-15m, the proton radius)
Might you know at what resolution do the scientist-scholars believe we will begin to “see” strings as in string theory? (10^-34 meters was Matt’s answer.)

Thank you.

Most sincerely,

Bruce

PS. Matt gave us permission to use the image of the two proton tracks on our website.  Of course, he expect that credit is given. Apparently he does not have his own personal homepage or homepage at CERN.
