Particle Physics course follow up
I am just following up on my OpenLearn particle phyiscs course review follow up.
As part of this I had to work out the charge spectrum on groups of 3 quarks.
This short article explains (or tries to) how to do this. Firstly thank to the course creators, Open Learn and the Open University without whom the course would not have been possible. Thank you also to users on the physics irc channel who gave me some help with doing this.
So if we take a Proton as an example, this has 3 quarks
uud
so firstly I had to write down all the possible combinations
uuu uud udu udd duu dud ddu ddd
There are repeated combiations here so by removing these we get
uuu ddd duu ddu
From here we then need to list the charges associated with each, and calculate totals
uud = 2/3 + 2/3 + 2/3 = +2e ddd = -1/3 + -1/3 + -1/3 = -1e duu = -1/3 + 2/3 + 2/3 = 1e ddu = -1/3 + -1/3 + 2/3 = 0
Now list the totals
+2e -1e 1e 0
if we put them in some sort of order
-1e 0 1e +2e
We get the charge spectrum
The activity had a sort of frurt machine that would come up with combinations of all the 6 quarks
u d s c t b
Details of where they fit in to the standard model and associated charges can be found on the standard model table.
This may sound complex, which is perfectly fine, once it was explained to be, and someone worked through it, it was much clearer, I decided to write it all down, and then type up here, as this helps to reinforce learning.
Given there are 6 quarks, the number of different combinations of 3 quarks is huge. Then think there would be anti baryons, so the same combination but with antiquarks
Mesons have combinations of 1 quark and 1 antiquark.

So following on from Septembers lecture, the Space telescope science institute present their next lecture.
You can find more upcoming (monthly) lectures below.

Cheaper to prevent pandemics than 'cure' them -
note: This article contains my personal thoughts on the topics presented, I would, of course, welcome open discussion on this.
This is another interesting BBC news article, raises some interesting points on how humans interact with wildlife.
I would guess it also highlights we need to also provide clean, running water to everyone on the planet, in a way that is, of course sustainable.
In another news article, again from the BBC, Denmark are in the process of culling mink, this was after it was found there is a mutated covid strain that could be passed on to humans.
Perhaps the solution to all this is very simple, and will push for clean water for washing, cooking etc. But also access to alcohol handwash in all places that handle animals,including fish. Ultimatlythere are calls to eat less meats anyway, especially beef,due to the climate impact alone.
We need to do something, so this could make a really interesting field of research, incorporating many disciplines it may mean ending some industries, so that will need retraining.
I would guess, if we are going to produce more alcohol based hand gels we need to ensure that there are no implications of or risks of this getting in to water streams.
Enigmatic fast radio burst pinned on magnetised dead star
This is an interesting development, astronomers have found something they have been spending years searching for. Not sure where these stars appear on the The Hertzsprung-Russell diagram.

The paper for this can be found on Physics World. Reported on IOPScience on 4th November 2020.
Currently discussing on a OU Science forum.

The search for life on Mars
One of the advantages of being a higher education student or in my case alumni is you get to join groups. I have just been watching a live webcast on the experiments that are being used onboard Mars rovers to look for possible indicators that Mars once supported life.
Exploring the Habitability of Mars with the Curiosity and Rosalind Franklin rovers and Orbital Missions
I am not sure if there is a recording of this going up, but the link to a some more information is here.
I am currently undertaking Particle Physics but there is also a really interesting series of lecutures on AstroBiology I want to check out too.

Meteorites Talk
Just been watching a really interesting talk by Dr Tim Gregory – Meteorites from 8th October 2020 – YouTube.
This was really interesting and accessible people with both a science and non science background,
Briefly touched on how the solar system was formed, protoplanetary disks looked at the two different types of asteroids, how they are formed, what makes them up internally, and finished off with a quick look at some of the organic molecules that have been found and how these could have found their way to earth.
Well worth a look, the video can be found on Youtube.
Thank you to the OU Science Club for pointing me to this talk.

National Chemistry Week 2020
18th to 24th October is National Chemistry week, so there are a few activities listed on the American Chemistry Society website out reach pages.
In recent chemistry news ScienceMagazine has an article on a Globular cluster in the Andromeda galaxy that appear to be deficient in elements heavier than Hydrogen and Helium.
This is interesting, there isn't that much information due to the need to sign in, but I would suspect the research papers may be more widely available in due course.
