Steve Myers was born in West Belfast, Northern Ireland and was taught mathematics and physics by priests, one of whom was the younger brother of the Cardinal of Ireland.
He more or less stumbled into electrical engineering at Queen’s University Belfast. He and four other friends were applying to the University. Only one of them had an idea of what to study. That young man’s father was an engineer who said electrical engineering was a profession under demand. All five of the young men, including Steve, put electrical engineering on the top of their applications.
This was a fortuitous choice for Steve as he eventually received a PhD from Queen’s University in Belfast.
He had another brush with synchronicity when his invitation to CERN was delayed by a long postal strike until the day before he was due in Geneva. He rushed to the interview and while waiting to be invited before the interviewers, he picked up a paper lying on the waiting room table. He noticed the term and concept of the "head tail instability" which has to do with electrons hitting the walls of the particle accelerator causing more electrons to leave the wall, creating an electron cloud that reduces the quality of the beam. Unknown to Steve at the time, this was a prime concern of his interviewers.
The resulting job, which he started in 1972, was Engineer-in-Charge of the operation of the Intersecting Storage Rings Collider (ISR). In 1979 he started working on the Large Electron–Positron Collider (LEP) which was the most ambitious collider to be built in its day. The design, approval, and construction took 10 years. A 27 km tunnel was excavated about 100 m underground with four large underground expansions of the cavern to house the detectors.
In the 1990s, he was chosen to be the Deputy Leader of the SPS (Super Proton Synchrotron)-LEP (SL) Division in charge of preparing the LEP Collider for physics. From 1996 until 2000, he was Project Leader of the LEP upgrade (LEP2). In 2000 Myers became Leader of the SPS-LHC (Large Hadron Collider)(SL) Division and in 2003 he rose to be Head of the Accelerator and Beams (AB) Department.
In 2009, he was appointed to be in charge of all the accelerator and technology activities at CERN as Director of Accelerators and Technology. Thus, he is in charge of the organization that has produced these groundbreaking results while it simultaneously uses all its colliders and develops new projects.
Through all these changes and challenges within the organizational hierarchy, he has stayed intimately familiar with how to coax the particles successfully around all the rings at CERN. Not bad for a young man from West Belfast who barely knew what electrical engineering was when he launched onto that career path.

Part 2: Northern Irish Scientist Works to Prove Higgs Boson Exists
In the last blog post, I discussed how Steve Myers is a physicist from Northern Ireland who is part of the team which is accumulating evidence of the Higgs boson. Then we found out some things about elementary particles that are smaller than electrons, protons, and neutrons, those old standbys of the particle world.
At the end, I said we ought to look at why we should care about finding the Higgs boson and while we are at it, see if the technologies on Star Trek are really possible.
As to why we should try to find the Higgs boson, let's look at the contributions of looking at small particles and elementary forces have produced in the past.
For instance, when radio waves were discovered, one of their discoverers thought they had no useful purpose. Now of course we have cell phones, microwave ovens, broadcast receptive radios and TVs, weather radar, wireless computing, and radar enabled speed traps! Or have they totally moved on to lasers?
Also, I joked/implied that Higgs boson might make some of the technologies in Star Trek possible.
I don't really know that, but imaginations and technology development have a habit of leap frogging off each other's backs.
Today's cell phones look suspiciously like the communicators on Star Trek. I've often said into my cell, "Scottie, beam me out of here."
The other side of the physics of elementary particle research is the implications beyond our confined lives.
I find spiritual comfort in the fact that each time we press the curtain to one side, we discover the creator of the universe has another exquisite wonderous layer which was working to make this universe the way it is.

Northern Irish Scientist Works to Prove Higgs Boson Exists
Steve Myers is a physicist from Northern Ireland who is part of the team which is accumulating evidence of the Higgs boson.
What is the Higgs boson?
It's an elementary particle.
It is really, really small. It's smaller than atoms, electrons, protons, and neutrons.
If you took science classes in the late 60s or early 70s, you probably remember the pictures of atoms as little balls called electrons circling a cluster of protons and neutrons. The cluster was the nucleus of the atom. The idea was much like planets going around the sun.
Then when you took chemistry in college, the professor and textbooks told you electrons traveled in orbitals. Some orbitals were spheres around the nucleus which seemed like the old model of electrons but the orbits could be anywhere at a set distance from the nucleus so you got a sphere the electron moved in, instead of a flat circular orbit.
But some of the orbitals looked like water balloons oriented around the central nucleus. Those looked odd, but then you really got your mind stretched because the professor told you the electrons weren't really particles and the orbitals were sort of clouds of positions of where the electron might be. The electron was a cloud? You probably thought, "Where did my particles go?"
To make matters worse, scientists continued to call electrons particles, even though they really meant they were clouds of where the electron might be if you forced it to become a particle for an instant.
But the clouds were really useful because if you brought two atoms together and their electrons could share the orbital clouds and satisfy the maximum number of electrons which that orbital liked to have, then you would have a really strong chemical bond. Also, if you excited the electrons to higher orbitals and then they electrons would fall back to their lower original orbitals and release energy in the form of light.
So it was tough to argue with clouds because they explained all the bond strengths and energy states so well. And the artists could show me the shaped clouds called orbitals, so I eventually got comfortable with them.
Fast forward to today, and all these particles have been determined to be made of smaller particles that again are not really tiny balls at all, at least no one thinks they are.
From Wikipedia, here are some particles that appear to make up the things we see or otherwise perceive:
"The 12 fundamental fermionic flavours are divided into three generations of four particles each. Six of the particles are quarks. The remaining six are leptons, three of which are neutrinos, and the remaining three of which have an electric charge of −1: the electron and its two cousins, the muon and the tau."
Stay with me.
These particles have properties called things like charge (like the property assigned to electrons, and protons), spin, and color. Spin isn't really what you are thinking of and color is definitely an odd term used to describe the nearly unexplainable. I haven't seen an artistic rendition of all these things yet. Do you have one?
Just a little more and we'll get to the Higgs Boson.
All 24 elementary particles are either fermions or antiparticles (depending on their spin). Don't ask. Just accept it.
The bosons either mediate forces or are the Higgs Boson.
If the Higgs boson exists, it has a spin of 0 and is responsible for the intrinsic mass of particles.
If it exists, the Higgs boson would most likely explain the existence of the Higgs Field.
The Higgs Field is suspected to exist everywhere, including in a perfect vacuum.
Here is what blows my mind:
My high school physics textbook was innovative for its time. It taught about the history of physics as well as the theories then present. In the 1800s there was this theory of aether (or 'ether' was another spelling) being a field that penetrated all space as a transmission medium for the propagation of electromagnetic or gravitational forces. It was an invisible lattice that allowed all elements and forces to work. In 1905, Albert Einstein himself shot down the whole theory of aether with his special theory of relativity.
Most physicists concluded that this theory of an aether was not a useful concept.
What amazes me is that after more than 100 years, the theory of physics has returned back to a field that exist everywhere, even in a vacuum!
