  • Cassini’s Finale (5/1/2017) - The Cassini space probe has got a serious date with Saturn coming up in the Fall on September 15th, but she’s got a very busy schedule between now and then making a series of dives through the space between Saturn and its rings.

  • Dark, Deep & Spooky… (8/8/2017) - Today’s physics is “probably” not the kind of thing that you, or at least your parents and grandparents, learned about in school (unless you happen to be a Physicist).

  • Ring o’ Fire, South (8/15/2017) - Song titles and colloquial terminology aside, you probably have an idea of what scientists mean when they talk about the “Ring of Fire” (National Geographic, Wikipedia). However, even if you do, a bit of review will be useful for this post. Here’s an imaginative 360° Video that provides a top-level introduction. Here’s a more mundane, … Continue reading Ring o’ Fire, South
  • RIP Rossetta! (10/1/2016) - The “Little Mission that Could” has come to an end, but what a mission it was to watch!

  • 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
  • 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).

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

Roget’s II (, Merriam-Webster Thesaurus, Visuwords


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
