In which I explain the Higgs Boson to my girlfriend, who is a biologist not a physicist.
Alex Wright: ok, so, first I should explain what a Boson is
Krista: ok
coles notes version please
Alex Wright:
alright, so, a boson is a field mediating particle, like a photon
are you familiar with the electromagnetic field?
Krista:
yes
Alex Wright:
ok, so the photon is the boson that mediates the electromagnetic field.
the field, and force, doesn't exist without and is made up of photons. If you excite the field to a certain energy, photons are released.
and we can observe them
Krista:
yes I understand that
Alex Wright:
it's like when you slosh around a bucket of water and some of the water at the surface splashes up into a drop separate from the larger body of water
ok, so that's the basics of bosons
the Higgs boson is a very special type of boson
You know that atoms are essentially 98% empty space, yes?
Krista:
ok
Alex Wright:
you've got your nucleus, and the electrons are floating around about as far away as jupiter from the sun, if we're talking scale here.
Krista:
yes
I know that
Alex Wright:
so most of the universe is about 98% nothing
but this doesn't really make sense, because if it was truly empty, everything would be zooming around at the speed of light
einstein's general relativity tells us that the thing that keeps particles form zooming about at light speed is mass.
some particles don't have mass, like photons and electrons, which obviously travel at light speed.
Krista:
ok
Alex Wright:
but what creates mass?
50 years ago, a smart guy named Peter Higgs suggested that that 98% of empty space wasn't empty at all, he hypothesized that this empty space was actually completely saturated with the Higgs Field
the Higgs field acts like a quantum molasses which slows down these particles as they travel through space.
Krista:
ooo cool
Alex Wright:
so, he proposed this 50 years ago, and described the phenomenon with mathematics, and it made sense
but the problem was, the Higgs field has such high energy, and because of Einstein's E=mc^2 equation, such high mass properties, it takes an immense amount of energy to excite the field enough to observe the particle
and then they did
Krista:
ohhh
Ok. wow I actually get it.
a few seconds ago
Alex Wright:
Yay
Krista:
you should post that explanation.
because every other one makes no sense.

Size of Earth compared to size of all Earth’s water,including obvious sources like oceans and lakes, but also from your atmosphere, you, your dog, and your tomato plant…,if the water were formed into one globe
The blue sphere (representing all Earth’s water) sitting on USA, reaching from about Salt Lake City, Utah to Topeka, Kansas, has a diameter of about 860 miles (about 1,385 kilometers) with a volume of about 332,500,000 cubic miles (1,386,000,000 cubic kilometers). 
About 3,100 cubic miles (12,900 cubic kilometers) of water, mostly as water vapor, is in the atmosphere at any time. If it all precipitated at once, Earth would be covered with only about an inch of water.
If all the world’s water was poured on USA, it would cover land, 90 miles deep (145 kilometers).

I would have guessed that the water globe would be bigger. What would you have guessed?
