<p>

see his Royal Instit. lecture &nbsp;pub &nbsp;Feb 15, 2017.</p>

<p>

JJ Thompson; &nbsp;and Ernest Rutherford: &nbsp;&nbsp;nucleus &nbsp;(fly in the center of a cathedral;... per Rutherford)</p>

<p>

best theories... no particles...</p>

<p>

fluid like substances... &nbsp;fields....</p>

<p>

spread everywhere thruout the Universe... &nbsp;can change in time...</p>

<p>

this room is the home of Michael Faraday... Friday eve discourses right here!</p>

<p>

E and M...</p>

<p>

he moved the small coil thru the big coil.... the light all around us...</p>

<p>

quantum field theory...</p>

<p>

waves of EM are light... &nbsp;&nbsp;waves made of particles....</p>

<p>

and applies to every single other particle in the Univers.</p>

<p>

the electron field... fills the entire Universe!</p>

<p>

all electrons in yourbody...are part of the same underlying electron field.</p>

<p>

&nbsp;

The vacuum: &nbsp;&nbsp;empty a box... pure vacuum... &nbsp;he shows a video of what it looks like...</p>

<p>

computer simulation of absolutely nothing: &nbsp;empty space... &nbsp;not dull and boring!</p>

<p>

the field is governed by QM...quantum vacuum fluctuations...</p>

<p>

Casimir force... force btwn two plates... more of this stuff on the outside than the inside.</p>

<p>

a single particle is far more complex than this... and 1023 is even harder.</p>

<p>

6 open problems in math....</p>

<p>

can you understand this from first principles....</p>

<p>

when fluctuations are calm and tame.... like a mill pond &nbsp;than a raging storm...</p>

<p>

g = 2.00... property of the electron particle</p>

<p>

it spins &nbsp;like the Earth... &nbsp;electron precesses....</p>

<p>

12 signif figs for g...</p>

<p>

should be possible to figure out the mass of the proteon...</p>

<p>

trying to do it for 40 years... we can get it to within 3% &nbsp;&nbsp;(that's all!)</p>

<p>

we have right equation but cannot really solve it....</p>

<p>

electron the neurtrino the up quark adnt the down quark...</p>

<p>

they're everywhere: &nbsp;&nbsp;....</p>

<p>

but actually &nbsp;&nbsp;we've got two more rows...</p>

<p>

muon &nbsp;(200X &nbsp;the elctron)</p>

<p>

and the tau &nbsp;(3K * mass of electron)</p>

<p>

strong force &nbsp;&nbsp;hold together quarks....</p>

<p>

strong... gluon field</p>

<p>

weak force: &nbsp;W and Z fields...</p>

<p>

space and time itself.... &nbsp;to general relativey... assoc with gravity...</p>

<p>

filled with &nbsp;&nbsp;12 matter fields &nbsp;and &nbsp;&nbsp;4 &nbsp;force fields....</p>

<p>

The Standard Model...</p>

<p>

Peter Higgs... 10-22 seconds.... &nbsp;&nbsp;a little bump &nbsp;in the data...</p>

<p>

shows the eqn for the Std Model... long line...</p>

<p>

it predicts the result of every eqn!!!</p>

<p>

first term...</p>

<p>

just solve R &nbsp;&nbsp;&nbsp;to get strength of gravity... &nbsp;apples &nbsp;and black holes...</p>

<p>

just solve for R....</p>

<p>

next term is &nbsp;&nbsp;EM....</p>

<p>

current limit of Knowledge....</p>

<p>

there's extra stuff... &nbsp;DM, &nbsp;Dark Energy... inflation...</p>

<p>

13.8 B years old....</p>

<p>

do not know what kicked off at T = zero.</p>

<p>

first 380K &nbsp;yars.... &nbsp;&nbsp;ev'e seen the fireball &nbsp;filled the Univ....</p>

<p>

it cools down....</p>

<p>

why did it flicker.... &nbsp;it lasted for 380K years....</p>

<p>

what caused the flocikerin.... &nbsp;&nbsp;quantum fields/ vacuum fluctuations...</p>

<p>

these ripples &nbsp;are in the fireball...</p>

<p>

taking place &nbsp;10-32 seconds after t zero.</p>

<p>

but what field is it... &nbsp;could be the Higgs... but probl something new!</p>

<p>

we want the polarizaiton of the light.</p>

<p>

LHC is most impt...</p>

<p>

then closed down for 2 years</p>

<p>

in 2015 now 2X the energy...</p>

<p>

&nbsp;

patterns in periodic table....</p>

<p>

shows &nbsp;EM &nbsp;equation.... &nbsp;&nbsp;v similar to &nbsp;eqn for strong and for nuclear force...

they all look similar...</p>

<p>

all obey the Dirac equation.... &nbsp;&nbsp;same for tau and muon etc.</p>

<p>

I dea of Unification....</p>

<p>

GUT grand unification....</p>

<p>

&nbsp;

Supersymmetry... &nbsp;matter and fields &nbsp;&nbsp;... simialr...</p>

<p>

and &nbsp;we have string theory... &nbsp;alll &nbsp;just one concept...</p>

<p>

but are they right....</p>

<p>

string theory &nbsp;no way to test at the moment...</p>

<p>

LHC... want to test these... &nbsp;running for 2 years... a perfect machine...</p>

<p>

but absolutely nothing!!! &nbsp;none of them are showing up!!!</p>

<p>

three responses....</p>

<p>

first to LHC.... &nbsp;&nbsp;just wait...</p>

<p>

response #2: &nbsp;&nbsp;our theoriesw must be correct... but we need a machine 10X as big!!!

but a new machine woudl cost $10B... forget it!</p>

<p>

(but maybe &nbsp;in China)...</p>

<p>

maybe... &nbsp;&nbsp;may build it!!! &nbsp;&nbsp;would take 20 years!</p>

<p>

#3 &nbsp;(his opinion)... &nbsp;&nbsp;</p>

<p>

but lots of mystery in this eqn....go back to drawing board.</p>

<p>

condensed matter phsyics &nbsp;or quatum info science... &nbsp;all have new ideas.</p>

<p>

he is optimistic.... &nbsp;hope we can do better than the Stfd Model.</p>
