A New Map of All the Particles and Forces

A New Map of All the Particles and Forces

This is an interesting new way to look at the standard model of particle physics that re-arranges things to better illustrate how different particles relate to each other.

The current diagram to present the standard model is below, this just shows the normal matter. I have one that shows anti matter too. In some ways this follows a similar layout to the periodic table

standard model

As an intermediate, diagram I actually like this diagram

standard model

Both the above diagrams are sourced from [1].

The new model called the 'double simple model' does look far more complex. However it has far more detail and better illustrates the relationship and interactions between the different forces / particles. You can view this at [1], while the paper describing how the team came up with this is at [2].

I have printed this, so it is something to discuss at the next STEM group meeting on the 12th March.

I think the paper at [2] has been around for a while, so this article is more on the Quanta Magazine article.

In a recent update it seems the mass of the W boson could throw a real spanner in the works regarding the standard model.

LibreOffice 7.3

LO 7.3

Version 7.3 of the Free, Libre, Open Source office suite is now available. You can read more about this here.

Documentation for 7.3 will be available shortly, in the meantime you can still download books for 7.1 & 7.2.

For those of you who dismiss LibreOffice. This is from the blog post.

LibreOffice offers the highest level of compatibility in the office suite market segment, starting with native support for the OpenDocument Format (ODF) – beating proprietary formats in the areas of security and robustness – to superior support for DOCX, XLSX and PPTX files. In addition, LibreOffice provides filters for a large number of legacy document formats, to return ownership and control to users.

Microsoft files are still based on the proprietary format deprecated by ISO in 2008, and not on the ISO approved standard, so they hide a large amount of artificial complexity. This causes handling issues with LibreOffice, which defaults to a true open standard format (the OpenDocument Format).

New Features Video

LO 7.2 install on Debian 11

*This worked for me, please use common sense and think before you do stuff, I am not responsible for damage to your system**

I have now downloaded and installed LibreOffice 7.2 on Debian 11.

  1. Goto https://www.libreoffice.org/
  2. Click Download Now
  3. For Debian 11, I selected the 7.2 deb file from the options
  4. LibreOffice7.2.5Linuxx86-64deb.tar.gz Save or move this to a sensible location, so maybe create a sub folder in downloads called Libreoffice
  5. Extract the gz file – this should be unzip *.gz
  6. Extract the tar file this should be tar -xf *.tar
  7. cd in to LibreOffice7.2.5.2Linuxx86-64deb 7a type ls to list files (for me I had 42 deb files)
  8. Goto a terminal
  9. Switch to root, with su - and enter password
  10. You will probably need to check working directory pwd
  11. cd to where your deb files are
  12. dpkg -i *.deb
  13. This should install everything
  14. You will find Libreoffice 7.2 on the menu (I am using xfce)

As always Your Mileage May Vary

Note, the LibreOffice 7.2 menu entries will be BELOW those for the previos install, my video here illustrates how to use menu editor to move them above the previous version.

Effect of long term space flight on the Brain

Study explores effects of extended spaceflight on brain

Scientists from the U.S., Europe and Russia are part of a team releasing the results of a large collaborative study involving the effects of long duration spaceflight on the brain.

Page citation : Medical University of South Carolina. “Study explores effects of extended spaceflight on brain.” ScienceDaily. ScienceDaily, 12 April 2022. www.sciencedaily.com/releases/2022/04/220412141100.htm

Positive note: Despite the current situation in Ukraine, those involved in science can still carry on working and collaborating, for the benefit of everyone.

LibreAdventure Testing 3

LibreAdventure Testing 3

libreadventure

Lots of work behind the scenes to iron out some bugs & problems with the software. I was involved with further testing on 15/3 and there is further testing planned for 17/3. This testing has also included load testing so we know the server will stand up to the number of users expected.

Looking good for the weekend. There will be a LibrePlanet post on Saturday with a link to this.

Building a ping pong ball shooter – part 2

Building a ping pong ball shooter

Further to the previous post, the ball shooter is now built up. I do need to solder this together, at some point. For now, it works as it is. This is the test I did at the library (more space).

Building a ping pong ball shooter

Building a ping pong ball shooter

As part of an order from Better Equipped, I sent for a ping pong ball shooter. This consists of two rotating disks, which propel a ping pong ball forward.

So far, I have only partly built this. I need to do some soldering to complete. I also want to find a safe place to test it. This project will be demonstrated at the Paignton Library STEM group, but could be used in a school too. This would support, Science, Maths, Design & Technology and possibly other subjects.
