As I am going to be writing posts that fall within the sciences, specifically Physics, Astronomy, Chemistry and related fields. I have decided to post here, the Greek and Hebrew Alphabet, which is used extensively in some of these fields.
In Overleaf, I have used a template letter file with an empty letter body area (or at least minimal). Copying this to a new file, keeps the original body empty for new files.
I have also created letters and letters-sent folders. This helps keep track of which letters are work in progress and which letters have been sent.
Once saved as pdf you can also attach to a e-mail if you wish to send a letter that way.
Use % at the start of a line (for example for the enclosures) to make the line a comment, if you are enclosing anything this can be put back in by removing the % from the start.
Using % makes that line a comment
$\LaTeX$ templates is a really useful website has templates that can help get you started.
I have just completed another OU / OpenLearn course, this time on The Evolving Universe. Despite its rather complex subject matter it was very interesting and expanded a little further on the 'How the universe works' course I undertook a few years ago.
The course looked at the early universe, the big bang, how particles, energy, time and temperature all changed over time and how all these are inter-related. How the matter we know today formed and why the universe is mostly matter and not antimatter. The fact there was more matter and what would have happened if the amount of antimatter and matter had been equal. Plus other interesting topics.
How sub-atomic particles such as Bosons, Leptons, Quarks etc interact. How research finds new particles and the huge energy levels required for this to take place.
This is a level 1 introductory course, and like the more formal course mentioned. The course also asks other questions which gets the reader thinking about different scenarios that could have occurred.
$\LaTeX$ is a typesetting system, that can be used to create professional looking documents. For example cover letters for employment, student applications, etc.
Its main use, however, is within academia. $\LaTeX$ excels at producing excellent looking reports, scientific papers, articles and has strong maths and science notation functionality.
for example:-
$CH_4$ for chemistry and $\frac{df}{dx}$ for maths as well as greek characters for example:-
$$\pi , \Sigma , \Omega , \alpha$$
I have been building some small electronics projects based on the 74HC/LS series of Integrated circuits. In essence these are small boards with a 14 pin IC holder soldered on, along with header pins of different colours for +V, GND, Input and outputs.
so far I have built two based on the 74HC00 Quad 2 input NAND gate and one based on the 74HC08 Quad 2 input AND gate. So far they work really well. I am hoping that these can be both powered by and used via a Raspberry Pi or Arduino. The intention is to build some boards up for use in teaching about digital logic.
I am setting up a new blog, to replace my existing [Wordpress blog] (http://www.zleap.net).
My current website / blog is hosted by a friend, who is moving and shutting down his web hosting operation(s). I am therefore using this as an opportunity to refresh my blogging activity and start again using what I would hope is a more efficient system.
I did look at Wordpress but this is very cumbersome and keeps e-mailing me regarding new features etc. I don't need anything special or spectacular.
What has attracted me to write freely is the fact it is federated. But this is built in with no need to install a word press plugin for activitypub.
I also like the look of the formatting options, as both Markdown and MathJax are supported. Which will make using LaTeX a lot easier within posts.
I will post more later. I need to set up a repository for pictures, so that I can include them in my blog.
