		<description>This is my first visit to your site and I am fascinated by the amount of particle physics I read here. I have read Leon Lederman&#039;s book &quot;The God Particle&quot; and I think I grasp the concepts behind Peter Higgs and his search for the elusive boson that imparts mass to other particles.

As an adherent to Francis Collins&#039; principles of theistic belief in the midst of scientific truth,
I am not  antagonistic to science, but much in accord with its  requirements of evidentiary testimony that explain the natural world. Inasmuch as many scientists had hedged their bets in the 1920&#039;s  on George LeMaitre&#039;s theory of the Big Bang because of his Catholic priesthood, it was necessary for me to know that he had based his research directly on Einsteins field equations to arrive at his concept of the primeval atom.

The reason is abundantly clear in both scientific and religious disciplines - that man should find signifcant meaning to his existence both in the natural and spiritual worlds. But it does not help to have a Nobel Laureate in particle physics announce to the world that he finds the universe &quot;meaningless.&quot;It is only by cooperation in the most  cosmic sense of the word, that we can mitigate the hostility that has been generated by the current crop of atheists who themselves are not scientists and have no connections to the scientific world.  There is evil apparent in all human endeavor, and we need to seek the paradise together that demonstrates our own human capacities to achieve this ideal world.</description>

		<description>It all depends upon the precise Inflaton mass (unknown), but the nearest natural scale is,
Mh = 2pi*alpha^8*Mp = 122.8 Gev, just ~ 2 Gev below the preliminary indication.
We shall see !</description>

		<description>Sounds like a great book, I can&#039;t wait to buy it.

Since you asked for input, here is one of my great wants:
An explanation of quantum entanglement and waveform collapse in such a fashion that I have some slam-dunk material to use next time my annoying new age friends and family start trying to talk about energy fields healing them, and their thoughts directly influencing the cosmos.  Ugh!
Even if this does not go in your book, please do a blog post.

Or if a fellow reader knows of somewhere something like this already exists, please post a link.
Thank you!</description>

		<description>The big problem I&#039;ve always had is - what&#039;s up with this bit about the vacuum not actually being a vacuum at all - and what happens if you take the stuff that makes up the vacuum out?  I know they keep saying you can&#039;t do that - but ... then you run into them talking about &quot;false vacuums&quot; and &quot;dirac seas&quot; where &quot;holes act like particles&quot;, and at some point, you have to wonder about Michelson-Morley experiments and the difference between this sea of negative particles and the aether - the difference is kinda sketchy!</description>

		<description>I think one of the bigger helpers I&#039;ve had in understanding the Higgs field is that slowing a particle down &lt;em&gt;is the same as&lt;/em&gt; granting mass because of the relativistic invariant m²=E²/c²-p²c². That is, suppose you have a particle that moves at the speed of light. It is necessarily massless because of the contraction of its four-momentum. As soon as &lt;em&gt;anything&lt;/em&gt; slows it down, that particle has mass. So the Higgs field doesn&#039;t &quot;give&quot; particles mass, it just slows them down. I feel like that&#039;s easier to understand than saying the interaction itself is directly responsible for mass. I think some people would say this is a semantic issue but it helped me a bit.

Maybe I&#039;m just proving why I don&#039;t write books on particle physics myself...</description>

		<description>I doubt the subject hasn&#039;t been explained &quot;well&quot; to a lay audience.  Rather, I suspect it&#039;s very difficult to explain to a lay audience better without high-level mathematics.

But I&#039;ll put it out there, nonetheless:  An explication of the role of gauge invariance and the Lie groups at the heart of the Standard Model.  Is there any way to intuitively grasp the nature of these symmetries as they relate to the forces the SM describes?  I&#039;ve never felt like I could.  I sort of get the idea that spatial rotations don&#039;t change certain laws, yadda yadda, but there are many kinds of &quot;local transformations&quot;.

This is the real meat of particle theory, it seems, what really makes it remarkable.  It&#039;s these symmetries that confer beauty, and it&#039;s arguably this kind of beauty most theorists search for as they attempt to go beyond the SM.  And for all that I&#039;ve read about it, I&#039;m convinced that I don&#039;t really understand it at all.  Maybe I never will, but I&#039;m always open to new takes on that subject.</description>
