These are organized by a classification scheme developed exclusively for Cosma. More…
Branches of science (also referred to as “sciences”, “scientific fields”, or “scientific disciplines”) are commonly divided into three major groups:
- Natural sciences the study of natural phenomena (including fundamental forces and biological life)
- Formal sciences the study of mathematics and logic, which use an a priori, as opposed to factual, methodology)
- Social sciences the study of human behavior and societies.
Natural and social sciences are empirical sciences, meaning that the knowledge must be based on observable phenomena and must be capable of being verified by other researchers working under the same conditions. — Wikipedia
science : (1) a department of systematized knowledge as an object of study (2) knowledge or a system of knowledge covering general truths or the operation of general laws especially as obtained and tested through scientific method — Webster See also OneLook, Free Dictionary, Wiktionary, Urban Dictionary
See also Access Science (McGraw-Hill)
Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Contemporary science is typically subdivided into the natural sciences, which study the material universe; the social sciences, which study people and societies; and the formal sciences, which study logic and mathematics. — Wikipedia

- Yellowstone, Beauty & Beast (4/30/2018) - If you have been Yellowstone National Park, then you know it is a vast, beautiful place with some fairly odd geologic features that smell bad, like rotten eggs. If you’ve never been there, then you might just have a fairly apocalyptic view of it because of the supervolcano under it that has been featured in … Continue reading Yellowstone, Beauty & Beast

- Visioning Spacesteads (8/8/2018) - Space, the final frontier… Humans have been imagining what it would be like to setup homesteads and live in space for about as long as they’ve been imagining how to get there, but the process didn’t really take off until after we actually got there. Back in the 1970’s NASA dedicated some resources to the … Continue reading Visioning Spacesteads
- Under the Ice (6/14/2019) - To paraphrase J.R.R. Tolkien’s famous words in The Lord of the Rings, “It’s a dangerous business, clicking on a link.

Better yet, they are beginning to share what they learned by doing it! Before we get into all of that, let’s go back and start at the … Continue reading Touch the Sun
- Too many sharks? (8/1/2018) - If you watch a lot of television, then you know that last week was the Discovery Channel’s Shark Week. Last year I did a post that coincided with it (Jaws vs. Jellies). However, this year I was leaning towards not doing more of something that is already a tad overdone. The Discovery Channel did add … Continue reading Too many sharks?

For example, Phys.org did a nice … Continue reading Super Bowl of Astronomy
- Strange Things (11/12/2016) - There’s been a ton of cool stuff going on in the 3D/360°/AR/VR hardware and software universe lately, and there’s about to be even more (more on that soon). On the other hand, the 3D/360°/AR/VR content front has been “relatively” static (unless you love Halloween’esque horror, of course). When I went looking for something interesting to … Continue reading Strange Things
- Spooky Space Sounds (10/30/2017) - NASA has a fun, albeit geeky, sense of humor sometimes. For example, this week they’ve released a compilation of “Spooky Sounds from Space.” Of course, since there is no air in space, there is no “real” way for humans to hear sound there. Instead, these are sounds generated by different types of scientific instruments when … Continue reading Spooky Space Sounds

Here’s a YouTube video … Continue reading Panda’s Playtime
- Octopuses from Space! (5/20/2018) - Did you hear the one about the octopuses from space? It sounds like the title of a cheesy sci-fi movie, doesn’t it? But it isn’t, this time, or at least, yet.

- Bird’s-eye Views (1/29/2019) - Humans tend to interact with animals as if they see the world in pretty much the same way that we do. However, the more scientists study animal vision, the more they tell us that’s just not the way that it is. Furthermore, what scientists know about animal vision goes way beyond the fact that our … Continue reading Bird’s-eye Views
- Barnum’s Critters (8/24/2018) - Barnum’s animals have escaped! Here’s an update about the situation from Inside Edition.
