About me

I am a principal network architect at QTS Data Centers. I joined QTS when they acquired Carpathia Hosting in 2015.
I have over 24 years experience in network design, operation and Unix/Linux systems.

I am also an amateur physicist, programmer, photographer, independent film producer and AFOL (read more).

11/24/2018 I wrote a program to search for polynomial-like formulas that have the charged lepton masses as their roots. The hope is
that such a formula would explain why there are exaclty three generations of matter, being the three real positive roots of a polynomial.
The program searches for fractional exponent "polynomials" since using integer exponents would require six terms instead of three
for three positive roots. The program has found thousands of possible formulas that predict the non-input variables to within their experimental
uncertainty but none of them have looked "simple" or "interesting" enough to publish so far. Since there are so many possible search factors
I am publishing the source here so others can take a crack at it if they want.

Latest source: lepton-3.37.tar.gz | GitHub - released 2019/05/25, updated with CODATA 2018 reference values, n-ball surface area, symmetry score, bug fixes.

01/31/2018 Supermoon in enhanced color:

Taken a few hours before the Lunar eclipse the color saturation was pushed during processing to exaggerate and reveal the
subtle colors that are present on the moon even when it is not eclipsed. Orange areas are due to an abundance of Iron oxide,
and purple areas are due to Titanium oxide. Copyright (c) 2018 Kevin M. Loch licensed under the creative commons 4.0 CC-BY license.

11/23/2017 New Paper:

Emperically derived fermion Higgs Yukawa couplings and pole masses

Abstract: Empirically derived formulas are proposed for calculating the Higgs field Yukawa couplings and
pole masses of the twelve known fundamental fermions with experimental inputs me, mu, and the
Fermi constant G0F.

11/11/2017: Here is a physics paper I wrote about fundamental particle masses (original verion 2/27/2017):

A new empirical approach to lepton and quark masses

Abstract: A novel alternative to the Koide formula and it's extensions is presented. A new lepton ratio with
a small dimensionless residual k_e = m_e m_t^2 / m_u^3 and mass scaling factor alpha_f = 27m_e / m_t are used to
construct empirical formulas for charged leptons, left-handed neutrinos and quarks. The predicted
masses are in excellent agreement with known experimental values and constraints.


I'm a terrible web designer but here are some websites I've built (and poorly maintained) over the years:

  • A simple, ad-free "check your IP address" website that supports IPv6 with several easy to remember url's:,
      and This site gets about 1.4 Million hits per day, mostly automated queries from scripts and various dynamic dns clients like inadyn-mt
  • I launched one of the earlier image hosting sites in April 2000. It is restricted to just LEGO related images.
      Today Brickshelf has over 4.8 Million pictures of original LEGO creations. At it's peak in 2006 it was receiving over a million
      page views from over 100,000 unique IP addresses per day.
  • Brickshelf at one time also held the worlds most complete repository of LEGO instruction and catalog scans. For many years LEGO customer support
      sent people to Brickshelf if they had lost instructions to older sets. That repository now lives at
  • For a while Brickshelf operated a generic image hosting site at (later moved to but had to shut
      it down as it was extremely unprofitable.
  • Since 1997 my ham radio site has run a solar storm monitor. For several years the late 1990's the monitor gif's were deep linked
      to directly from the Art Bell radio show homepage. It was fun to watch the huge spike in traffic whenever he would say on the air "go to my
      website now!". It is stil gets over a million deep links per day from several ham related sites like and
  • I once built a tiny webserver out of an Atari 800 and a Bridge Communications (now 3com) CS-210 terminal server.

    Other hobby stuff:

  • I was co-founder of the original BrickFest, The world's first AFOL convention that operated from 2000-2005. Today there are over 35 AFOL
      conventions operating around the world.
  • What do I build with LEGO? Usually large city buildings.
  • I operate (along with other volunteer control operators) two Amateur radio repeaters in the Washington DC area using the call
      sign N3KL. 145.13 MHz and 1286.1 MHz


  • While at Carpathia I was the engineer who had to shut down network connectiviy to Megaupload when the FBI seized the file sharing site in 2012.
  • My father Frank J. Loch (1943-2008) worked for NASA during the Apollo program as an engineer for the spacecraft communications systems. In 1971
      he moved to Virginia and started working for the CIA. While he never told me anything aobut his work at the CIA, I've been able to reverse engineer from public
      sources that he likely worked on the Satellite Data System and KH-11spy sstellites. According to wikipedia the first KH-11 satellite was launched
      on my 5th birthday.
  • My grandfather's cousin invented the toaster oven. My father 1 and brother 1, 2, 3 also have patents.
