6 FREE and open-source programmes that might help you make great presentations

 You don't necessarily need to shell out a tonne of cash to get decent presentation software. There is no shortage of free, web-based or desktop-based programmes that may help you make professional-looking presentations for any event. We may examine a number of possibilities, some of which are open-source.

OpenOffice

Quite comparable to Microsoft Office, OpenOffice is a free suite of productivity applications. You can discover programmes that can help you make presentations, spreadsheets, and text documents, among other things. The UI isn't great, but it's easy to pick up and use. If you have experience with Microsoft Office, you will be able to get going fast.

Regarding presentations, OpenOffice lets you make expert-level slideshows with features seen in paid programmes. Additionally, there are dozens of community-created templates to help you get started right away, as this is one of the most downloaded free programmes in the world. Additionally, it works well with Microsoft PowerPoint, so you won't have any trouble opening PPT and PPTX files.

OpenOffice is open-source software, which is something else to keep in mind. Simply put, this implies that you are welcome to access and make changes to the OpenOffice GitHub page where the project's source code is located. Additionally, you may submit feature requests and bug reports on this website for the community to review.

Reveal.js

Using web technologies like as HTML, CSS, and JavaScript, Reveal.js allows users to create presentations that can be seen in a web browser. The application is free and open-source. Do not assume that you must be an expert web programmer in order to utilise it; in fact, the opposite is true. The fundamentals of HTML are all you need; they're not hard to pick up and use. It is recommended that you learn CSS, while it is not required.

From YALE UNIVERSITY: Yale scientists made an unusual discovery: The tree with 1,000 billion living beings VIDEO

A group of scientists from Yale University in the United States, who conducted a large study published in the prestigious journal Nature on August 6, 2025, made an amazing, completely out-of-the-ordinary discovery.

The scholars found that a single tree can host a trillion (1,000 billion) living things (microbes). The researchers took samples from 150 living trees of 16 species in the northeastern United States and found that these internal communities of microbes are not random.

A single living tree can host about a trillion microbes in its wood, with distinct communities in the inner and outer layers. This is not a rounding error - it forces a rethinking of what tree health and forest function really means, according to Earth. Jonathan Gewirtzman, a doctoral candidate at the Yale School of the Environment, led the study with the support of collaborators from several disciplines at Yale University in the United States.
